[0002] Coal gas is a gas containing combustible components processed from coal as raw material. According to the processing method, coal gas properties and use, it is divided into: water gas, semi-water gas, and air gas (or producer gas) obtained by coal gasification. These gases have a low calorific value, so they are collectively called low calorific value coal gas; the gas obtained by coking in coal dry distillation is called coke oven gas and blast furnace gas; it is a medium calorific value coal gas and can be used as civilian fuel in cities; the carbon monoxide and hydrogen in coal gas are important chemical raw materials.

[0003] In the process of gas transmission and distribution, pipelines are usually required for transportation, and the connection between pipelines is usually done by using valves. Because gas contains impurities during transportation, the impurities will have a certain impact on the valve over time, thereby reducing the service life of the valve. In addition, the existing valve mechanism is simple, and if gas leaks after the valve is closed, it will be impossible to promptly alert the staff to take emergency measures. Therefore, those skilled in the art provide a gas safety control valve to solve the problems raised in the above background technology. Utility Model Content
