Air Shut-off Valve
Internal combustion engine overspeed is inevitable, especially in the petroleum and chemical industry, when the equipment is running, combustible gas into the engine will cause overspeed, not only damage the engine and the driving system equipment, and even cylinder explosion accidents, resulting in casualties of terrible consequences.
Description
Working principle:
Meter set, quickly close the valve and mechanical lock, cut off the engine intake circuit, so that when the valve receives the control signal, the electromagnet drive valve of the trip motor speed immediately decreased and stopped.
After the valve is triggered to close, it must be manually reset (the ordinary electric parking design has safety risks: when the diesel engine pump group is automatically reset after the power failure) in line with the requirements of the national standard mechanical reset.
