This valve seat has the following characteristics:
(1) There is an angle in the sealing surface 40&
(2) There is an R2 semicircular groove at the bottom of the sealing valve seat;
(3) Clearance shall be reserved for fitting with valve body; It can increase elasticity.

How to explain the principle of noise elimination and shock absorption of stainless steel pneumatic butterfly valve
Everyone knows that the stainless steel pneumatic butterfly valve has the function of shock absorption and noise reduction, and has good flexibility. How about its principle?
The exhaust pipe is composed of two pipes with different lengths, which are separated first and then intersected. Since the length difference between the two pipes is equal to half of the wavelength of the sound wave emitted by the car, the two rows of sound waves cancel each other when they intervene when they are superimposed, which weakens the sound intensity and reduces the sound, thus achieving the effect of silencing.
The sound is caused by vibration. To reduce the sound, shock absorption of the vibrating object is required. The principle of the muffler is: exhaust gas enters through the inlet, is cut and compressed by a perforated baffle in front, enters the second stage, and the third and fourth stages are finally discharged into the atmosphere. The stainless steel pneumatic butterfly valve is mainly used to compensate for the axial, transverse and angular displacement of the pipeline, It can also be used to absorb noise. It is generally composed of receiving flange
The stainless steel corrugated pipe is formed by its own expansion absorption pipe deformation and convenient installation, and the sealing pump is connected with the hose to play its own advantages. It has been widely used in the water treatment workshop of steel plants, petrochemical wharves, refineries, shipyards, high-rise buildings, etc.
In the pipeline system composed of pumps or compressors, valves, instruments, etc., vibration often damages key components such as instruments, affecting the normal operation of the system, causing resonance of the pipeline system, destroying the system and equipment, and causing serious noise pollution. The pump connected hose developed by our company can effectively absorb pipeline vibration and reduce noise.
