Safety alarming type circulating gas guide valve

Abstract

The invention discloses a safety alarming type circulating gas guide valve. The guide valve comprises a left valve block and a right block valve block, and the left valve block and the right valve block are spliced left and right to form an integrity; a gas importing short tube is communicated with the center of the right end of the right valve block, a conical mobile block is arranged at the outlet of the left end of the tube body of the gas importing short tube, and a horizontal gas circulating channel is formed in the left side directly facing the conical mobile block, in the middle of theright side of the block body of the left valve block; a reset spring is further arranged on the left rod body of a guide sliding rod in a sleeving mode, the spring left end of each reset spring is fixedly arranged on the left wall of an inner cavity of a rectangular groove, the spring right end of each reset spring is fixedly arranged on the left wall surface of a sleeve body of a guide sliding sleeve, and an alarm is further arranged on the upper surface of the left valve block. The safety alarming type circulating gas guide valve solves the problem that traditional overpressure gas cannot beinformed and serious safety accidents can be caused, effectively guarantees the safety of workers and meets higher gas valve application requirements.

Description

technical field [0001] The invention relates to the technical field related to valves, in particular to a safety alarm type circulating gas pilot valve. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Among them, gas valves, valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in ext...

AI Technical Summary

Problems solved by technology

Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems. When it is large, it can lead to serious safety accidents due to the inability to know the real-time pressure situation, which can cause the occurrence of serious safety accidents to be unguaranteed and affect the actual application effect. Such problems need to be solved
