General as long as the qualified factory hydraulic lifting platform will be set explosion-proof valve, it's main role in the pipeline burst, to prevent the rapid decline in the elevator table accident.
Hydraulic system pipeline explosion-proof valve is normally open valve, in the free stream direction are normally open, in reverse, when the oil back flowing through the explosion-proof valve, through the orifice differential pressure is smaller than the spring of the spring force, so the valve port, and keep it always open, and when one end of the valve pipeline burst, making orifice at one end of the pressure is zero, so at this point, spring is far less than pressure loop, the explosion-proof valve is closed. Therefore, to prevent the heavy object to decrease risk.
