Butterfly pneumatic valve characteristics and performance of 3)

butterfly pneumatic valve closing member ( Pneumatic disc or disc) Disk around the axis of pneumatic valve, realize the opening and closing, the main purpose of the pneumatic valve from closed and throttling. Pneumatic valves open and close, is one of the CD disc, around its axis of rotation, or adjust the pneumatic valve body, achieve the goal of opening and closing. Pneumatic valve is fully open to the barrier is usually less than °, pneumatic valve and butterfly butterfly itself is not self-locking ability, in order to install the CD in pneumatic valve stem and worm reducer. Worm gear reducer, not only can make with self-locking ability, CD, the CD in any position to stop, but also improve the aerodynamic performance of the valve. The characteristics of specific industry, the high temperature butterfly higher pressure range pneumatic valve, pneumatic valve nominal diameter, carbon steel pneumatic valve, pneumatic valve plate rubber seals, metal ring ring instead. Large manufacturing high temperature with steel plate, used for high temperature smoke duct and the gas pipe welding the main media of the pneumatic valve. Butterfly pneumatic valve has the following advantages:, open/close convenient and rapid, saving energy, fluid resistance small, can often operate. , simple structure, small volume, light weight. , portable, apertures mud water at least. , low pressure, can achieve good sealing. And good regulation performance. Faults are as follows: brake pneumatic valve, working pressure and temperature range is small. , poor sealing. The butterfly structure can be according to the deflection plate, vertical plate, inclined plate and leverage. Can be divided into two kinds of seal, according to the form than the seal. Soft seal type commonly used rubber ring seal, seal type commonly used metal ring seal. Can be divided into the circular wafer is depending on the type of connection flange connection; Transmission mode can be divided into manual, gear transmission, pneumatic, hydraulic and electrical several differences. Adjustment of the pneumatic valve installation and maintenance should be paid attention to the following:, when installation, pneumatic valve in the closed position. , the open position to the disc rotation should be determined. , with the ventilation valve the pneumatic butterfly valve, open the vent valve should be taken before opening. , the installation instructions shall be installed in the factory a big butterfly, the weight of the set a solid foundation.
