The invention provides a safety
system for preventing gas leakage and explosion, and belongs to the technical field of gas conveying
control equipment. The problems of complex structure, complex internal operation and the like in the prior art are solved. The safety
system for preventing gas leakage and explosion is arranged between
combustion equipment and a gas main pipeline which is communicated with the
combustion equipment and is used for conveying gas, and comprises a gas valve arranged on the gas main pipeline, the safety
system further comprises a gas
exhaust pipe which is connected tothe position, located between the gas valve and the
combustion equipment, of the gas main pipeline, communicates with the gas main pipeline and is used for discharging gas located in the position ofthe gas main pipeline. The safety system for preventing gas leakage and explosion has the advantages that one of the gas valve and the
gas explosion-proof valve is selectively pressed through left-right swing of the swing arm on the electric swing
assembly to selectively control one of the gas valve and the
gas explosion-proof valve to be in an open state, the safety system is simple in structure,convenient to operate and control, good in sealing performance, good leakage-proof and explosion-proof effect, and convenient, safe and reliable to use.
