squib restrictor valve

Abstract

The invention belongs to a control device on a medium pipeline and particularly relates to a pipe explosion flow-limiting valve which can effectively control the flow rate of a medium in the pipeline after the pipeline has a pipe explosion accident. The pipe explosion flow-limiting valve comprises a valve body of which the two ends are provided with medium runner pipes, a mounting hole is formed in a housing of the valve body, a valve cover is arranged outside the mounting hole for sealing with the valve body, and the pipe explosion flow-limiting valve further comprises a diversion body, a flow-limiting body, a support and movement structure, a sliding block and a sliding rod which are arranged in the valve body, as well as a damping device for movement of the sliding block and a tension trigger structure for the movement of the sliding block which are arranged outside the valve body. The pipe explosion flow-limiting valve disclosed by the invention has the advantages of reasonable and simple structural arrangement and flexibility in action, and is particularly suitable for pipe explosion flow-limiting of large-scale water pipelines in powerless regions.

Description

technical field [0001] The invention belongs to a control device on a medium pipeline, and in particular relates to a bursting flow limiting valve capable of effectively controlling the flow rate of a medium in the pipeline after a bursting accident occurs in the pipeline. Background technique [0002] Long-distance medium output pipelines, such as large-scale water supply pipelines, are laid along geographically long distances. The existing pipeline control design adopts conventional control valves such as valve opening and closing. When accidents such as pipe rupture and pipe burst occur on the pipeline, the medium in the pipe will be ejected from the rupture and burst quickly, causing the pipe flooding accident; at the same time, the pressure in the pipe changes sharply, which will cause extreme damage in the pipe. Ground impact, for water pipelines, will produce water hammer impact, affecting the safety of other parts of the pipeline. How to solve the above problems, t...
