High temperature check structure characteristics and working principle of the pneumatic valve

high temperature and check the working principle of pneumatic valve:
check pneumatic valve is by open-close part by medium flow and power on or off, in order to prevent the backflow medium pneumatic valve is called check pneumatic valve. Check pneumatic valve belong to automatic pneumatic valve class, mainly used for medium on the one-way flow of pipeline, only allowed to medium flows in one direction, in order to prevent accidents.

the structure characteristics of high temperature check pneumatic valve:
check pneumatic valve according to its structure, can be divided into the lift check pneumatic valve, swing check valve and butterfly check three kinds of pneumatic valve. Aerodynamic lift check valve can be divided into vertical and horizontal two kinds. Swing check pneumatic valve is divided into single type, more than double disc type and disc type 3 kinds. Butterfly check pneumatic valve as straight through, the above several check pneumatic valve in the connection form can be divided into the threaded connection, flange connections and welding of three.
