Gas pipeline detection valve structure

Abstract

The invention relates to the field of pipeline gas valve equipment, in particular to a gas pipeline detection valve structure capable of detecting the pressure of a gas pipeline in time and cutting off a gas source in time. A pressure control device slides in the range of a guide groove and comprises a magnetic component, the magnetic component and a membrane attract each other to form magnetic attraction, and the pressure control device drives a gas inlet closing system to realize opening and closing through a torsion spring lever; when the gas pressure in a main shell is larger than the magnetic attraction, the membrane is away from the magnetic component, and the pressure control device descends and drives the gas inlet closing system to achieve closing of a gas inlet; and when the gaspressure in the main shell is smaller than the magnetic attraction, the membrane is close to the magnetic component, and the pressure control device descends and drives the gas inlet closing system toachieve closing of the gas inlet. The gas pipeline detection valve structure is particularly suitable for being used in the gas pipeline.

Description

technical field [0001] The invention relates to the field of pipeline gas valve equipment, in particular to a gas pipeline detection valve structure. Background technique [0002] With the development of society, gas has become a necessary fuel energy for industry and life. However, in the process of residents using gas, various leakage, poisoning, fire or explosion accidents occur almost every day, especially due to gas micro-leakage or out-of-control pressure regulation of gas pressure regulators and soft hoses falling off and breaking, etc. Most of the accidents caused by poisoning, fire or explosion have seriously affected the harmony and stability of the society. The existing gas pipeline detection valves often cannot accurately detect the pressure, and cannot automatically close and cut off the gas source in time. It is more difficult to prevent the occurrence of gas leakage and fire and explosion accidents well, and it is impossible to better guarantee the safety of ...

However, in the process of residents using gas, various leakage, poisoning, fire or explosion accidents occur almost every day, especially due to gas micro-leakage or out-of-control pressure regulation of gas pressure regulators and soft hoses falling off and breaking, etc. Most of the accidents caused by poisoning, fire or explosion have seriously affected the harmony and stability of the society. The existing gas pipeline detection valves often cannot accurately detect the pressure, and cannot automatically close and cut off the gas source in time. It is more difficult to prevent the occurrence of gas leakage and fire and explosion accidents, and it is impossible to better guarantee the safety of gas consumption.
