Heavy hammer type safety working principle of pneumatic valve

what is the job of the pneumatic valve safety hammer? Security pneumatic valve, also known as hammer lever pneumatic valve. It consists of pneumatic valve, pneumatic valve seat, pneumatic valve, rod, hammer, etc. Pneumatic hammer safety valve working principle is: through the fulcrum hammer rod and dry, the pneumatic valve core seat and close the pneumatic valve agent size, the weight of steam pressure from the bottom of the spool, when steam pneumatic valve agent in force on the formation of the fulcrum, over time of hammer from pneumatic seat be top, steam discharge waste gas, the fulcrum pneumatic valve to open the safe. Adjust the position of the rod hammer, can be achieved from pressure pneumatic valve seat adjustment. Hammer type pneumatic valve has simple structure, convenient adjustment, reliable work, but the size and weight is bigger, to the low voltage, small boiler used as pulse pneumatic valve large capacity boiler suitable high parameter.
