Let us know the scope of application and structure of pneumatic butterfly valve?
Do you know what the pneumatic butterfly valve is used for and what structure it is composed of? Here is a detailed introduction.
Pneumatic butterfly valve (VibrationDamper), which is mainly used to restrain the shock of spring rebound after shock absorption and impact from the road surface. When passing uneven roads, although the shock absorption spring can filter the vibration of the road, the spring itself will have reciprocating motion, and the pneumatic butterfly valve is used to restrain the spring jumping. If the pneumatic butterfly valve is too soft, the body will jump up and down. If the pneumatic butterfly valve is too hard, it will bring too much resistance. The barrier spring works normally. During the modification of the suspension system, the hard pneumatic butterfly valve should be matched with the hard spring, and the hardness of the spring is closely related to the vehicle weight. Therefore, the heavier vehicles usually use the hard pneumatic butterfly valve. The device connected with the vibration inducing crankshaft is used to counter the vibration of the crankshaft.
The structure of the shock absorber is that the piston rod with the piston is inserted into the cylinder to flush the oil in the barrel. The piston is provided with an orifice so that the oil in the two spaces separated by the piston can supplement each other. Damping is generated when viscous oil passes through the orifice. The smaller the orifice, the greater the damping force. The greater the oil viscosity, the greater the damping force. Assuming that the size of the orifice is unchanged, when the working speed of the shock absorber is fast, excessive damping will affect the impact absorption. Therefore, a disc shaped leaf spring valve is set at the outlet of the orifice. When the pressure increases, the valve is jacked open, the orifice opening increases, and the damping decreases. Because the piston moves in both directions, leaf spring valves are installed on both sides of the piston, which are called contraction valves and extension valves respectively.
The above content was organized and started by Songxia Xizhen Pneumatic Butterfly Valve Co., Ltd. If anyone who is interested in our metal pneumatic butterfly valve can leave a message on this website, or often pay attention to this website, we will have a detailed introduction.

4. Because the impurities in the medium or the welding slag of the new pipeline scratch the sealing surface of the single pneumatic control valve, causing internal leakage. Solution: The new pipeline must be purged, or a filter must be installed in front of a single pneumatic control valve. Once internal leakage occurs, the single seat pneumatic control valve can be disassembled, the valve core and valve seat can be reground, and then assembled for use.
