wet type alarm valve -tsmj-101371
Operation principle:Condition of a fire takes place in some area in the protected system, glass ball of the sprinkler head (temperature sensing component) is broken, when the sprinkler head open and spray water to put out the fire, the water pressure of wet type alarm valve’s exit side pipe network drops; Valve petals of upper and lower both sides form difference of pigeonholing, when the difference reach certain value, the valve petals are opened, the source of water is filled and enter into the pipe network to put out the fire constantly. The aperture that water flows through in the seal groove flows into the delay device at the same time, after delayed by 5-90S, the alarm bell of excited water conservancy is given out and called the police sound; The pressure switch operates and send out alarm to the warning control system, start the fire control pump to begin to supply water of the pipe network at the same time. Reach the result of scheduling to put out the fire
