A cylinder type gas valve cut-off device

Abstract

The invention relates to the technical field of gas safety and protection devices, in particular to a cylinder type gas valve cutting-off machine. The cylinder type gas valve cutting-off machine comprises a ball valve on a gas pipeline and a deceleration base, a passive gear is arranged on a valve shaft of the ball valve, a sliding groove is formed in the deceleration base, a piston cylinder and acontroller are arranged on one side of the deceleration base, a rack is arranged at the front end of an output shaft of the piston cylinder, and the rack is engaged with the passive gear to conduct transmission; and a three-way magnetic valve is arranged on the piston cylinder, one end of the three-way magnetic valve communicates with the gas pipeline, the controller is electrically connected with the three-way magnetic valve, and a combustible gas concentration sensor, a power source and an alarm are arranged on the controller. According to the cylinder type gas valve cutting-off machine, the structure is reasonable, when a detection value of the combustible gas concentration sensor exceeds a standard, the three-way magnetic valve is switched in the gas pipeline to obtain pipeline pressure, a piston drives the rack to drive the ball valve to be close the gas pipeline, and information interaction can be conducted by a wireless module; and the controller sends out alarm prompting information, auxiliary power is not needed, the integral structure is stable and reliable, and the gas leakage risk can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of gas safety devices, in particular to a cylinder type gas valve cut-off device. Background technique [0002] With the development of society, people's material and cultural living standards have been significantly improved. As a household energy device to improve people's living conditions, gas stoves have been widely used in both urban and rural areas. However, in the process of using gas, accidents such as gas explosions and poisoning caused by gas leakage and exhaust gas have occurred from time to time, which have brought serious threats to people's lives and property safety. Gas leakage alarms can effectively monitor combustible gas in the environment. The concentration of gas or toxic gas can be controlled, and the gas supply can be automatically cut off to prevent further leakage of gas, which plays a role of safety precaution. There are various styles of gas leakage alarm devices on the market. Th...
