Adjustment characteristics and use methods of the pneumatic valve, pneumatic valve adjustment, the characteristics of triple eccentric butterfly characteristics of pneumatic valve

the connection type can be divided into flange and clamp connection; According to the transmission can be divided into manual, gear transmission, pneumatic, hydraulic and electric several
butterfly pneumatic valve ( Butterflyvalve refers to shut down a ( Pneumatic disc or disc to disc, revolve around pneumatic valve shaft to a pneumatic valve open and close, mainly in the line cut off and throttling. Butterfly pneumatic valve opening and closing is a disc-shaped butterfly plate, the pneumatic valve body around its own axis of rotation, so as to achieve the aim of opening and closing or adjust. Butterfly pneumatic valve fully open to the barrier is usually less than °, pneumatic valve and butterfly butterfly pole itself has no self-locking ability, in order to butterfly plate positioning, in the pneumatic valve stem with worm gear reducer. The use of worm gear reducer, can not only make the butterfly plate with self-locking ability, make the butterfly plate to stop at any position, can also improve the aerodynamic performance of the valve. Industrial special high temperature the characteristics of the pneumatic valve adjustment ability, apply pressure range is higher also, large nominal diameter pneumatic valve, pneumatic valve body is made of carbon steel, pneumatic valve plate seal using metal ring instead of rubber ring. Large high temperature butterfly pneumatic valve USES the steel plate welding manufacturing, mainly used for the duct smoke and gas of high temperature medium. Adjusting the advantages of the pneumatic valve is as follows:, easy opening and closing rapidly, energy saving, small fluid resistance, can often operate. , simple structure, small volume, light weight. , can transport the mud, and the apertures least accumulated liquid. , low pressure, can achieve good sealing. And good regulation performance. Adjustment of the pneumatic valve faults are as follows:, working pressure and working temperature range is small. Poor, sealing. Butterfly pneumatic valve can be divided into the form of the structure offset plate, vertical plate, inclined plate and leveraged. Can be divided into the form of the sealed type seal and hard seal type two kinds. Soft seal type generally use rubber ring seal, metal hard seal type usually adopt ring seal. According to the connection type can be divided into flange and clamp connection; According to the methods can be divided into manual transmission, gear transmission, pneumatic, hydraulic and electric. Adjustment of the pneumatic valve installation and maintenance should be paid attention to the following:, when installation, pneumatic disc to stop in the closed position. , open position should be according to the butterfly plate to determine the Angle of rotation. , with the ventilation valve the pneumatic butterfly valve, open before you by the first open the vent valve. , should be in accordance with the manufacturer's installation instructions for installation, big weight the pneumatic butterfly valve, should set up a solid foundation.
