The pneumatic valve gate of shallow condition and operation?

in recent years, with the development of science and technology in our country and the people's livelihood, pneumatic bellows gate valve not only influence on industry is gradually expanding, corrugated pipe gate pneumatic valve in the field of civil awareness has also been gradually improve. Today small make up take you to understand the application of the pneumatic valve bellows gate under working condition and operation.
pneumatic bellows gate valve is closed ( Ram) Along the pathway of the center line of the vertical direction of the pneumatic valve. Pneumatic bellows gate valve in the pipeline can only be fully open and close to cut off the use, not for adjusting and throttling. Pneumatic bellows gate valve is a kind of pneumatic valves use range is very wide, average diameter DN of mm or cutting device to choose it, sometimes diameter small pneumatic bellows gate valve is used in the cutting device also.
pneumatic bellows gate valve sealing face has two gate, the most commonly used pneumatic bellows gate valve two sealing surface form of wedge, the wedge Angle vary with parameters of pneumatic valve, usually, when the medium temperature is not high for ° '. Pneumatic wedge bellows gate valve disc can be made into a whole, is called a rigid disc; Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic disc.
pneumatic bellows gate valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the pneumatic valve seat sealing surface pressure to ensure that the seal face seal, this is the seal. Most of the pneumatic valve is to use force sealed bellows gate, the pneumatic valve is closed, to rely on outside force forced the ram pressure to the pneumatic seat, to ensure the sealing surface sealing.
pneumatic bellows gate valve gate for linear motion with pneumatic valve stem, called lifting lever pneumatic bellows gate valve ( Also known as pneumatic rod bellows gate valve. Usually in lifting lever on the trapezoidal thread, through the nut at the top of the pneumatic valve and pneumatic valve guide groove, the rotary motion to linear motion, which is the operating torque thrust into operation.
open the pneumatic valve, corrugated pipe gate when the gate hoisting height is equal to the pneumatic valve size: The Times, the fluid channel open completely, but at runtime, the position cannot be monitored. Actual use, is a pneumatic valve stem apex as a sign, that is fixed position, as its full open position. To consider locking phenomenon in a temperature change, usually in the open to the vertex positions, then rewind / - circle, as the position of the pneumatic valve fully open. As a result, corrugated pipe gate pneumatic valve fully open position, according to the location of the damper ( > the trip.
