Abstract

The present invention relates to a gap automatic safety pressure regulator. Said pressure regulator includes leather cover, upper cover gas chamber, pressure-regulating gas chamber, gas inlet tube, gas outlet tube, clamping plate, pressure-regulating spring, pressure bar, control chamber and safety spring. Said invention also provides the connection mode of all the above-mentioned components and its working principle. If the gas is leaked, the gas source can be automatically cut off by means of safety pressure regulator.

Description

Technical field [0001] The invention relates to a gas automatic safety pressure regulator. Background technique [0002] At present, the popularity rate of household gas use in our country is getting higher and higher. While gas brings many conveniences to people, it also endangers people's life and property safety at all times. Now, gas leakage, poisoning, fire, explosion, etc. are caused by the use of gas. Various safety accidents are also increasing day by day. Although there are some security products developed for the safety of gas pressure regulators on the market, these products all have defects that cannot be ignored: some have introduced gas sensing electronic devices in their structures, and their structures are both Complicated and impractical, once there is no electricity, all security functions will be lost; some will only alarm but will not automatically cut off the gas source when an air leakage accident occurs. Therefore, it can be said that in the existing...
