Problems solved by technology

[0002] At present, due to the structural characteristics of the existing valves, it is impossible to effectively solve the problems of resource loss and environmental damage caused by pipe bursts, especially the traffic problems, production problems, life problems and environmental problems caused by pipe bursts in tap water systems in cities all over the world. problem, a worldwide problem
The existing one-way pipeline burst control valve abroad can only control the upstream medium through the actuator and the energy system, and the resources in the downstream pipeline are still uncontrollable
Casualties and economic losses caused by bursting of high-temperature and high-pressure steam pipelines are also disastrous

Abstract

The invention discloses a core tube valve capable of achieving automatic cutting duringbothway pipeline burst. The core tube valve is a sub series of conventional core tube valve plate blocks in the original core tube valve mother series. The valve core tube is a fixed part which coaxially penetrates through a sleeve tube I of a valve body, an inner cavity of the valve body and a sleeve tube II ofthe valve body; an axial partition layer is arranged on the middle part of the valve core tube; two axial adjacent sides of the partition layer are separately equipped with at least one radial circulating hole of an input section and an output section; a ring-shaped valve element which surrounds the partition layer and a ring-shaped valve seat on the throat part of the sleeve tube I and the throat part of the sleeve tube II define a sealing pair; the input section and the sleeve tube I are in shaft hole type fit, and the output section and the sleeve tube II are in shaft hole type fit; a pressure element is arranged between the input section and the end part of the sleeve tube I, aninner cavity of the pressure element communicates with front pressure of the valve through a channel; a pressure element is arranged between the output section and the end part of the sleeve tube II, and aninner cavity of the pressure element communicates with back pressure of the valve through a channel; and when a pipeline in any direction is burst, the valve body instantaneously moves axially to cut off medium flow. The core tube valve is simple in structure, is flexible in opening and closing, is safe and reliable, and protects resource, life and environment.

Description

technical field [0001] The two-way pipe burst self-cutting core pipe valve of the present invention belongs to the field of valves, and is a sub-series of the conventional core pipe valve plate in the core pipe valve mother series invented by myself. Background technique [0002] At present, due to the structural characteristics of the existing valves, it is impossible to effectively solve the problems of resource loss and environmental damage caused by pipe bursts, especially the traffic problems, production problems, life problems and environmental problems caused by pipe bursts in tap water systems in cities all over the world. The problem is a worldwide problem. The existing one-way pipeline burst control valve abroad can only control the upstream medium through the actuator and energy system, and the resources in the downstream pipeline are still uncontrollable. Casualties and economic losses caused by bursting of high-temperature and high-pressure steam pipelines are ...
