Desuperheating decompression pneumatic valve technology is introduced

desuperheating decompression is pneumatic valve adopts pneumatic control valve body of the opening of the opening and closing of regulating the flow of medium, the medium pressure is reduced, desuperheating decompression pneumatic valve at the same time with the aid of the role of the pneumatic valve after pressure adjust the opening of open-close part, keep the pneumatic valve after pressure in a fixed range, and the spray after pneumatic valve body or pneumatic valve into the cooling water, reduce the temperature of medium, the pneumatic valve is called decompression desuperheating pneumatic valve. The characteristics of the pneumatic valve, is under the condition of the inlet pressure changing, keep exports to pressure and temperature in a certain range. Vacuum pneumatic regulating pneumatic valve pneumatic valve is a necessary accessories, main effect is to air pressure decompression and stability to a fixed value, in order to regulate the pneumatic valve to obtain stable gas source power for regulating control. According to the structural form can be divided into the diaphragm, diaphragm spring, piston, lever and bellows type; According to the pneumatic seat number can be artificial single-seat type and two-seater type; According to the position of the pneumatic disc different can be divided into positive action and reaction type. According to the working medium can be divided into the steam pressure pneumatic valve, air pressure pneumatic valve, gas pressure pneumatic valve, etc.
