The characteristics of the electric pneumatic wedge gate valve

two electric pneumatic wedge gate valve sealing surface and pipe axis, namely two wedge check pneumatic valve, water generally 'Angle' of the seal face,, and wait for a few kinds, size according to the Angle of the high and low temperature, generally the higher the temperature, the Angle should be taken to reduce the temperature, the possibility of a wedge introduction. Electric pneumatic valve pneumatic wedge gate valve is a straight line, it's on the Z - Match the rotary actuator, and intelligent switch type. The pneumatic valve is the most common simple open breath valve, use the up and down the door opening and closing of the working fluid pipe. Widely used in electric power, metallurgy, petroleum, chemical industry, paper making, sewage treatment and other industries. First, the characteristic. Fluid resistance small, erosion and erosion by the media, Halls open) Sealing surface. Open the more powerful, sealed performance is good, the media flow is not restricted, don't add flow, not downward pressure. 。 A simple shape, excellent manufacture process, use range. 。 Low precision requirements for sealing surface Angle; 。 The temperature rise will not cause the phenomenon of wedge; 。 Sealing surface can join the pad wear compensation. 。 Close the pneumatic valve requires less torque.
