Description

Technical Field

[0001] The utility model relates to the technical field of gas valves, in particular to a new type of gas emergency cut-off valve device. Background Technique

[0002] The gas emergency cut-off valve is mainly a safety product used in gas pipelines. It is connected to a combustible gas alarm. When the combustible gas alarm detects gas leakage, the combustible gas alarm will send a pulse signal to the gas emergency cut-off valve at the first time, and the gas emergency cut-off valve will perform a valve closing action to cut off the gas source from the source to ensure safety.

[0003] However, the existing new type of gas emergency cut-off valve device has the following disadvantages:

[0004] (1) At present, this kind of gas emergency cut-off valve is aimed at the situation of gas leakage. Once leakage occurs, its cut-off valve can cut off emergently. However, for the situation where gas is ignited by an open flame, the open flame is likely to damage the electronic components that turn off the cut-off valve, resulting in the inability to turn off the cut-off valve. Professional personnel are required to turn it off, and it takes a lot of time for professional personnel to arrive at the scene, delaying the rescue process. At the same time, when some electrical electronic components are in use, there is a risk of fire when they meet gas, which has a certain safety hazard.

[0005] Therefore, the utility model provides a new type of gas emergency cut-off valve device. Content of the Utility Model

[0006] (1) Technical problems to be solved

It solves the problem that the current gas emergency cut-off valve is aimed at the situation of gas leakage. Once leakage occurs, its cut-off valve can cut off emergently. However, for the situation where gas is ignited by an open flame, the open flame is likely to damage the electronic components that turn off the cut-off valve, resulting in the inability to turn off the cut-off valve. Professional personnel are required to turn it off, and it takes a lot of time for professional personnel to arrive at the scene, delaying the rescue process.
