Double eccentric butterfly pneumatic valve installation gas quantitative analysis

the double eccentric butterfly pneumatic valve gas in real life has been very widely used, double eccentric butterfly pneumatic valve gas is usually by the Angle of travel electric actuators and control pneumatic valve as a whole through the mechanical connection, after installation and debugging. Double eccentric butterfly pneumatic valve gas according to the movement pattern classification are: switching type and external regulation. Will come here to do further about electric pneumatic valve regulating butterfly.

double eccentric butterfly pneumatic valve installation points gas analysis:
) Double eccentric butterfly pneumatic gas valve installation position, height, import and export direction must comply with the design requirements, pay attention to the direction of the medium flow shall conform to the direction of the arrow by pneumatic valve body, connection should be firmly connected. The best and most practical bo combustion website to provide you with a better platform for the gas industry.
) Double eccentric butterfly pneumatic valve gas appearance inspection must be conducted before installation, pneumatic valve nameplate shall comply with the current national standard 'general pneumatic valve symbol' GB regulation. Pressure is greater than for the job. MPa and pneumatic valve with the function of cutting on ZhuGanGuan, strength and strict performance test should be done before the installation, qualified rear must use. Strength test, the test pressure for the nominal pressure. Times, duration of not less than min, pneumatic valve shell, packing should be no leakage as qualified.

double eccentric butterfly pneumatic valve gas 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.

double eccentric butterfly pneumatic valve gas 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.

double eccentric butterfly pneumatic gas valve installation and maintenance:
, when installation, pneumatic disc to stop in the closed position.
and open position should be according to the butterfly plate to determine the Angle of rotation.
, with the ventilation valve the pneumatic butterfly valve, open the ventilation should be taken before opening valve.
