Abstract

Una estructura de válvula de compuerta, que comprende: un cuerpo de válvula dotado de unos pasos de flujo de entrada y de salida, con una c¿ñamara de válvula ente ambos, una compuerta montada en la camara de válvula entre ambos, una compuerta montada en la camara de válvula, con movimiento entre unas posiciones de abierta y cerrada respecto a dichos pasos de flujo o de circulación, un vástago de válvula que se extiende a partir de la compuesta y es movible dirección axil, en sentidos opuestos, para mover la compuerta de una a otra de sus posiciones de abierta y cerrada, un embolo conectado con dicho vástago de válvula, un cilindro que recibe a dicho embolo ajustado en su interior y presenta una camara cerrada de presión por uno de los lado del embolo, destinada a recibir un fluido a presión que obligue al embolo y al vástago de válvula a ir en un primer sentido, en la dirección axil del vástago de válvula, unos medios elásticos flexibles par amover dichos embolos y vástago de válvula en unsegundo sentido ,opuesto a dicho primer sentido, en ausencia de presión de fluido, en dicha camara de presión por encima de un nivel prefijado, un miembro de tuerca conectado a rosca con dicho vástago de válvula, un apareja de topes separados a cierta distancia y situados de modo que dicho miembro de tuerca tome contacto de aplicación con ellos, impidiendo que el miembro de tuerca se mueva en sentido axil sobre dicho vástago de válvula mas alla de unas posiciones de limite, moviendose de ese modo dicho vástago de válvula en sentido axil al seguir girando dicho miembro de tuerca después de alcanzadas dicha posiciones de limite, un manguito recibido en dicho miembro de tuerca, en relación corrediza o de acción telescópico con el y destinado a poder girar movido desde el exterior del cuerpo de válvula y unos medios de acanaladura so estiras de chaveta que conectan dichos manguitos y miembro de tuerca de manera que la rotación de dicho manguito se traduce en una rotación de dicho miembro de tuerca, pero que permite el movimiento relativo entre dichos manguito y miembro de tuerca en la dirección axil de dicho vástago de válvula, de tal modo que dicho manguito puede hacerse girar en sentidos opuestos para efectuar el movimiento axil de dicho vástago en ambos sentidos primero y segundo citados, con el fin de mover dicha compuerta de una a otra de sus posiciones de abierta y cerrada.
