Válvula de bola Trunnion

A válvula de bola de muñón es un importante dispositivo utilizado para regular el flujo de fluidos como gas, petróleo o vapor en una tubería. Una válvula de bola de muñón consta de un disco en forma de esfera en el centro. Gira para regular el ciclo de flujo. Algunas de estas válvulas también vienen con un dispositivo antiestático, antivuelco y de bloqueo que garantiza su estabilidad. Somos líderes fabricante de bolas de muñón y ofrecer productos duraderos y de alta calidad.

Estructura de la válvula de bola de muñón

La estructura de un válvula de bola de muñón es la siguiente:

Cuerpo: El cuerpo de la válvula mantiene en su sitio la parte interior de la válvula de bola. Su cuerpo puede estar hecho de varios materiales, como dúplex, superdúplex, inconcluso, acero inoxidable, acero al carbono y acero al carbono de baja temperatura.
Bola: Un disco inicia o detiene el flujo en un movimiento de rotación. La bola permanece fija en una posición cuando gira.
Asiento: El asiento de un válvula de bola de muñón alrededor de la bola. Garantiza que la bola esté en su sitio cuando se enciende el actuador. Los hay de dos tipos: blandos o de teflón y metálicos.
Muñón: El muñón es un eje adicional presente en la válvula de bola de muñón, que impide que la bola se mueva desde abajo. La función principal de esta pieza es mantener la bola en su posición. En el caso de una válvula de bola flotanteEl muñón se fija al disco esférico mediante uniones soldadas.
Vástago: el vástago asegura la conexión entre el actuador y la bola. El vástago se conecta a la bola y el eje la mantiene fija en su sitio.
Inyección: está presente en la zona del vástago y el asiento. Cuando se produce una fuga, actúa como sello parcial para detenerla.
