El acoplamiento de prueba de presión del sello cónico está compuesto por un núcleo de válvula cónico, un sello cónico y un resorte.

El sello cónico y el núcleo cónico de la válvula están firmemente unidos a la superficie de acoplamiento cónica del cuerpo de la válvula bajo el empuje de precompresión del resorte.

Estructura interna de la prueba de presión sellada con cono

Características del sello cónico: el núcleo de la válvula cónica y el sello cónico funcionan juntos, el sellado es de contacto superficial, el efecto de sellado es mejor y el gas y el líquido son universales;

El resorte está integrado en el cuerpo de la válvula y no es fácil de aflojar; pero la precisión de procesamiento del cuerpo de la válvula y el carrete es relativamente alta.

Como equipo de uso común en la industria, los puntos de prueba de presión de fluido son conocidos por su amplio rango práctico y conexión y muestreo convenientes. Especialmente cuando el fluido se usa a alta presión y caudal, tiene muchas ventajas y muchas comodidades.

Entonces, cuales son sus ventajas:

Ventaja 1: la operación se puede completar manualmente a alta presión

Cuando el fluido está a alta presión, si la operación es descuidada, la presión más alta puede hacer que el líquido se escape fácilmente, provocando accidentes de proceso irreversibles e incluso potencialmente mortales.

Sin embargo, el conector de la manguera de prueba de presión tiene esto en cuenta por completo, de modo que el conector se puede desconectar y cerrar simplemente usando ambas manos a alta presión.

Ventaja 2: estructura pequeña

Debido a que las ubicaciones de muestreo y prueba de presión a menudo no son fijas, el trabajo debe realizarse de acuerdo con condiciones y requisitos específicos.

Por lo tanto, la forma compacta brinda una gran comodidad en la ingeniería de transporte y operación.

Luego está la capacidad de conectarse fácilmente con el medidor.

Debido a su propósito único, la conexión con el instrumento se considera completamente en el diseño, por lo que la operación es fácil y la conexión es firme.

3. Resumen

Los adaptadores de punto de prueba son un componente muy pequeño en el sistema hidráulico, pero juegan un papel importante en la depuración, prueba y diagnóstico del sistema hidráulico.

A través del manómetro o sensor, se pueden completar varias pruebas de presión sin desmontaje y montaje y sin fugas.

El ajuste razonable de los accesorios de los puntos de prueba de presión en el sistema hidráulico aporta mucha comodidad a la depuración, prueba y diagnóstico.

Para garantizar un buen efecto de aplicación, es muy importante elegir un producto fiable y de alta calidad.

La evaluación actual del punto de prueba de presión es muy buena y el diseño del producto es excelente.

Al tiempo que garantiza una gran salida de flujo, también puede garantizar estrictos estándares de detección de calidad, de modo que los productos puedan tener un mejor valor de uso.

A juzgar por la situación actual, los acoplamientos de prueba de presión también se aplican principalmente de manera flexible a varios sistemas de fluidos.

Sin embargo, el cableado interno de los diferentes sistemas de fluidos y el tamaño de los conectores son diferentes, por lo que debe realizar el control de flujo con anticipación antes de comprar el punto de prueba de presión correspondiente.

Si el tamaño no coincide, también es un problema.

¿Cuáles son los tipos de accesorios y conjuntos de mangueras hidráulicas?

Con el rápido desarrollo de la maquinaria de construcción de China, la confiabilidad de los conjuntos de mangueras hidráulicas se ha convertido en uno de los temas más preocupantes de la industria.

El conjunto de la manguera hidráulica es un elemento básico en el sistema de transmisión hidráulica. La calidad del conjunto de mangueras afecta directamente el rendimiento del sistema hidráulico y el motor principal. Parte de la falla del conjunto de la manguera proviene de la estructura del núcleo de la junta.

El núcleo del conector de la manguera se divide principalmente en dos partes, una es la estructura de conexión, basada principalmente en las normas SAE, ISO y KES; La otra parte es la estructura de la parte de engarzado (estructura de la cola), que se combina con la chaqueta exterior y las capas de goma interior y exterior de la manguera para formar una deformación de engarzado confiable para cumplir con el rendimiento del conjunto de la manguera.

Si la estructura de la pieza de engarzado del núcleo de la junta no es razonable en el diseño de diferentes tipos de mangueras, se producirán problemas de calidad del producto en gran medida.

Por lo tanto, los tipos de núcleos de unión (diseñados) seleccionados para mangueras en diferentes entornos de trabajo también son diferentes, y un diseño razonable puede evitar o reducir la aparición de fallas.

1. Tipos y características de los racores de manguera

En toda la industria del ensamblaje de mangueras, existen principalmente dos tipos de conexiones confiables entre las juntas de manguera y las mangueras: juntas de manguera de retención total y juntas de manguera desmontables.

La junta de engarzado completo es un proceso en el que el módulo de engarzado de ocho partes de la máquina engarzadora aprieta uniformemente la junta de la manguera hasta cierto punto después de ensamblar el núcleo de la junta, la manguera y la camisa exterior, de modo que la junta de la manguera y la manguera se conviertan en un todo .

El conector de manguera desmontable comprime la manguera a través del núcleo del conector con el cono exterior y el núcleo del conector, de modo que la manguera está cerca del cono interior del manguito del conector, formando una conexión con una mayor fuerza de unión.

1.1 Forma y características del engarzado de la manguera

El tipo de retención de la manguera depende principalmente del tipo de manguera (o del tamaño de la goma interior y exterior) y el entorno de presión del conjunto de la manguera.

Se divide principalmente en tres categorías: engarzado de caucho que no se despega, engarzado de caucho exterior que se despega y engarzado de caucho interior y exterior.

Las características de cada tipo son:

(1) No se pela ni se engarza: no es necesario pelar el caucho interior y exterior de la manguera, y el producto se puede completar engarzando después de instalar la manguera. La tecnología de procesamiento es simple.

Este tipo de engarzado se utiliza a menudo para mangueras trenzadas de alambre de acero con capas externas de caucho relativamente delgadas, como las normas GB / T3683, EN853 y SAE.

(2) Pelado y prensado: es necesario quitar la capa de goma exterior de la manguera a una cierta longitud (la capa de goma exterior es más gruesa), que se utiliza para hacer que la capa de refuerzo de alambre de acero entre en contacto con la ranura del diente de la chaqueta.

Cuando la chaqueta se contrae y se deforma bajo una fuerza externa, doblará firmemente el alambre de acero, evitando así que la junta se salga cuando se somete a un impacto de alta presión.

Este tipo de engarzado se aplica principalmente a mangueras enrolladas con alambre de acero, como las normas GB / T10544, EN856 y SAE.

(3) Pelado y engarzado de caucho interno y externo: las capas de caucho interna y externa deben pelarse a una cierta longitud (el grosor del caucho interno y externo), la capa de alambre de acero y la capa de caucho interna se extruyen en una onda forma, generalmente adecuada para GB / T10544, EN856-R13, R15, etc. Especificaciones (32 o más incluyendo 32) manguera espiral de alambre de acero de ultra alta presión.

1.2. Conector de manguera tipo retención

La junta de manguera de tipo de retención se compone principalmente de un núcleo de junta, una camisa exterior (la tuerca es una parte opcional) y otras partes.

1) Materiales, tipos y características del núcleo de la junta

Los materiales comúnmente utilizados para núcleos de juntas son aceros 20, 35 y 45. Para núcleos de juntas rectas, a menudo se utilizan aceros 35 y 45, que tienen una gran resistencia a la deformación. Teniendo en cuenta la capacidad de fabricación de los núcleos de juntas por flexión, generalmente se utilizan aceros 20 o 35.

Con la popularización de la tecnología de doblado en caliente, los aceros 35 y 45 también se pueden utilizar para núcleos de articulaciones de codo.

Las características estructurales del núcleo de la junta están estrechamente relacionadas con la forma de engarzado de la manguera y, según la regularidad de la estructura, los tipos de núcleos de la junta se dividen a grandes rasgos en: estructura en zigzag, estructura rectangular, estructura de bloqueo interno, etc.

(1) El núcleo de la articulación con estructura de diente de sierra, comúnmente conocido como tipo de púas, se compone principalmente de ranuras en diente de sierra, y el ángulo entre la hipotenusa y el eje generalmente no supera los 20 °.

La parte superior del dentado tiene forma de arco o plana, y el plano y el lado corto del dentado son esquinas redondeadas lisas (0,2 ~ 0,5 mm) para evitar daños en la capa de goma interior de la manguera durante el montaje y el engarzado.

El núcleo de la junta de esta estructura tiene una fuerte resistencia al sellado y al arrancamiento, y se utiliza principalmente para mangueras de caucho enrolladas con alambre de acero.

(2) Núcleo de junta de estructura rectangular: compuesto principalmente de varias ranuras rectangulares, los cuerpos de 5 ~ 7 ranuras forman una ranura de sellado y la profundidad de la ranura es generalmente de 0,3 ~ 0,6 mm.

La superficie de transición entre la parte superior de la ranura y la parte inferior de la ranura es generalmente lisa con esquinas redondeadas, con un radio de 0,1 mm ~ 0,3 mm.

Evite que se dañe la capa de goma interior de la manguera durante el montaje y el engarzado. La estructura general es simple, con buen rendimiento de sellado, pero baja resistencia a la extracción. Esta estructura se usa a menudo para mangueras de resina, mangueras trenzadas de alambre de acero y otros tipos de mangueras.

Con la popularización de la tecnología de doblado en caliente, los aceros 35 y 45 también se pueden utilizar para núcleos de articulaciones de codo.

Si la estructura de la pieza de engarzado del núcleo de la junta no es razonable en el diseño de diferentes tipos de mangueras, se producirán problemas de calidad del producto en gran medida.

(3) Núcleo de la junta de la estructura de bloqueo interno, también conocida como estructura anti-extracción.

Este tipo de estructura está especialmente diseñada para evitar que la manguera se salga de la junta de la manguera, y la estanqueidad está asegurada por la estructura rectangular.

Por lo tanto, el núcleo de la junta de la estructura de bloqueo interior es en realidad una combinación de la estructura anti-extracción y la estructura rectangular.

Este tipo de junta tiene las características de alta confiabilidad y larga vida útil. Se utiliza principalmente para mangueras de bobinado de alambre de acero de gran diámetro y presión ultra alta y ensambles de mangueras de bobinado de alambre de acero dinámicas en condiciones de trabajo duras.

2) Material, tipo y características de la tapa exterior

El material de la camisa exterior es generalmente acero 20, y la buena deformación plástica del material se utiliza para hacer que el tubo de caucho extruido con dientes de la camisa exterior y el núcleo de la junta se ajusten.

También hay muchos tipos de tapas exteriores, principalmente para diferentes núcleos de juntas, diferentes entornos de trabajo, diferentes condiciones de trabajo específicas y diferentes formas estructurales requeridas.

Por lo general, el lado interior de la chaqueta está formado por algunas ranuras o estrías. Hay ranuras cuadradas, trapezoides, zigzags, etc., que deben usarse junto con diferentes tipos de núcleos de juntas.

Los tipos de estructura de tapas exteriores comúnmente utilizados se dividen aproximadamente en los siguientes tres tipos:

(1) Revestimiento de ranura de diente en forma de onda. La superficie exterior de la chaqueta ondulada es principalmente un cilindro liso, y el ángulo entre la hipotenusa del diente interior y el eje es de 25 ° ~ 45 °.

El lado radial y la hipotenusa están conectados por esquinas redondeadas de 0,2 ~ 0,5 mm, generalmente compuestas por 3 ~ 5 dientes internos. Principalmente adecuado para conjuntos de mangueras de presión media y baja que no se pelan, como tubos de resina y mangueras trenzadas de alambre de acero; Se puede usar junto con la estructura de diente de sierra y el núcleo de la junta de la estructura rectangular, con una débil resistencia a la extracción y una tecnología de procesamiento simple.

(2) Revestimiento de ranura de diente trapezoidal. La superficie exterior es un cilindro liso y la superficie interior es una ranura con un cierto número de dientes trapezoidales.

El ángulo entre la hipotenusa y el eje es de 25 ° ~ 45 °, y cada dentado es una ranura rectangular. La parte superior del dentado es un plano con un ancho de 1 a 2 mm, y las esquinas afiladas tienen una transición con una esquina redondeada de 0,2 mm.

Se puede utilizar junto con un núcleo de junta de estructura rectangular para formar una resistencia de extracción efectiva, adecuada para pelar tuberías trenzadas de media y alta presión y tuberías enrolladas.

(3) Cubierta alveolar compuesta. La superficie exterior es una ranura en forma de T correspondiente a la dislocación del diente interno, y la superficie interna es una ranura con un cierto número de dientes trapezoidales bilaterales.

Es adecuado para su uso con el núcleo de la junta de la estructura de bloqueo interno y se usa para el ensamblaje de mangueras de alta presión y gran caudal.

Con el desarrollo gradual de la maquinaria de construcción a gran escala, el sistema hidráulico también se desarrolla constantemente en la dirección de alta presión, y la aplicación de esta forma estructural se está volviendo cada vez más extensa.

2. Selección de la cantidad de prensado de juntas

De acuerdo con los diferentes tipos de mangueras y tipos de juntas, la cantidad adecuada de prensado también es un factor clave para garantizar que el conjunto de mangueras no presente problemas.

La cantidad de prensado afecta directamente el rendimiento del sellado, la resistencia al arrancamiento y la vida útil.

Generalmente, al juzgar la calidad de la deformación por engaste, observe si el espacio entre la superficie del diente interno del manguito externo y la ranura del diente del núcleo de la junta se llena con el tubo de goma.

Solo cuando se satisface la deformación se puede garantizar la resistencia a la extracción y el rendimiento de sellado.

En términos generales, la cantidad de prensado de la manguera de goma interior, como el caucho de nitrilo, debe hacer que la capa de goma interior se comprima (40% ~ 45% para manguera trenzada de alambre de acero, 50% ~ 55% para manguera enrollada de alambre de acero de cuatro y seis capas); La cantidad de prensado del tubo de resina y la manguera de PTFE asegura que la cantidad de compresión de la capa de caucho interior sea de 25% a 30%.

En el caso de asegurar el precinto, cuanto menor sea la retención, mejor. Mediante cálculo y verificación, se selecciona una cierta cantidad de retención.

3. Conclusión

El artículo analiza los tipos de núcleos de unión y tapas exteriores que se utilizan en el conjunto de manguera de retención.

Cuando el engarzado de la manguera tiene problemas de calidad y los tipos de fallas.

Analicé las razones y cómo utilizar una configuración de prensado razonable y juntas de prensado, para evitar el problema del bajo rendimiento del ensamblaje de la manguera causado por una estructura de prensado de manguera irrazonable.

Mejore y controle de manera efectiva la confiabilidad del conjunto de mangueras, y también brinde un fuerte apoyo para el rápido desarrollo de diversas maquinarias de ingeniería hidráulica.
