Gas clamping valve

Abstract

The invention discloses a gas clamping valve, which is characterized in that: a valve body is provided with a valve cavity with a cavity structure, a soft diaphragm is arranged in the valve cavity, the diaphragm is supported by a diaphragm connecting rod mechanism and sealed and covered by a valve cover, the diaphragm connecting rod mechanism consists of a diaphragm connecting rod fixedly arranged in the center of the diaphragm and an adjusting rod for adjusting the diaphragm connecting rod, and adjusting rod sealant particles for sealing a nozzle in the valve cavity are arranged on the adjusting rod; a valve core of an air outlet adjusting device is a cone valve core; a safety device is an explosion-proof device and consists of an explosion-proof ejection rod, an explosion-proof ejection rod spring and explosion-proof rod sealant particles; and the matched surface of the explosion-proof rod sealant particles and the valve body is circular. The clamping valve structure of the invention has the advantages of excellent low-pressure performance, high gas utilization rate, stable output pressure, good leakage-proof effect in safe pressure and high explosion-proof sensitivity over safe pressure.

Description

technical field [0001] The invention relates to a valve body device for a stove, in particular to a gas cassette valve which combines the functions of a pressure reducing valve and a gas valve. Background technique [0002] Cassette stove is a well-known tank-type gas cooker. Because of its small size, easy to carry and easy to use, it has been widely used by people. However, there are many safety hazards in portable cassette stoves, and explosions sometimes occur. Cassette stoves There are many reasons for the explosion, but in the end it was because the internal pressure of the liquefied gas tank installed on the stove was higher than the safety standard, and the user continued to use it without knowing it. The explosion was not the stove but the gas tank, and the consequences were very serious; At present, the valve bodies of cassette furnaces on the market generally have the phenomenon that the bottom gas of the bottle cannot be used up. It is difficult to control the fl...

[0002] Cassette stove is a well-known tank-type gas cooker. Because of its small size, easy to carry and easy to use, it has been widely used by people. However, there are many safety hazards in portable cassette stoves, and explosions sometimes occur. Cassette stoves There are many reasons for the explosion, but in the end it was because the internal pressure of the liquefied gas tank installed on the stove was higher than the safety standard, and the user continued to use it without knowing it. The explosion was not the stove but the gas tank, and the consequences were very serious; At present, the valve bodies of cassette furnaces on the market generally have the phenomenon that the bottom gas of the bottle cannot be used up. It is difficult to control the flow rate. , easy to flameout, summing up the above shortcomings, it is obvious that the valve body of the existing cassette furnace does not meet the safety requirements of people
