Introduces a heavy hammer pneumatic valve type safety is how to work

heavy hammer type safety pneumatic valve is also called lever type pneumatic valve, it consists of pneumatic valve, pneumatic valve seat, pneumatic valve core, leverage, composed of main components such as a heavy hammer.
heavy hammer type safety working principle of pneumatic valve:
the weight of the heavy hammer through leverage and pivot role in pneumatic valve stem, the air pressure in the pneumatic valve core seat, to close the pneumatic valve, steam pressure by lower effect on the pneumatic valve core, when the force acting on the pneumatic valve core steam to force moment, which is formed by the fulcrum is greater than the weight of torque, which is formed by the fulcrum pneumatic valve core were jacked up to leave the seat, steam to emissions, the security of pneumatic valve to open. Adjust the position of the hammer on the lever of security can be realized pneumatic valve pressure adjustment.
heavy hammer type safety pneumatic valve has the advantages of simple structure, convenient adjustment and reliable work, but its size, weight is large, suitable for medium and small boiler, in large capacity boiler high parameters used for pulse pneumatic valve. （ Yue feeds)
