What are the reasons why the rubber pneumatic butterfly valve is ineffective?
Any pneumatic butterfly valve has its limitations. For example, spring pneumatic butterfly valves cannot be used for vibration isolation of machines with similar frequencies in many places, and air cushion pneumatic butterfly valves may not be used for vibration isolation of on-board equipment. But this does not mean that they have no shock absorption effect, only that they are not suitable for use in some places. The same is true for rubber pneumatic butterfly valves. Rubber pneumatic butterfly valve is suitable for high-frequency vibration equipment, and also suitable for some stamping type vibration. The effect is very good! Finally, many rubber pneumatic butterfly valves on the market only need the appearance, no lining! Their design premise is not designed according to the vibration reduction requirements at all. Such products cannot be called pneumatic butterfly valves at all, which is the root cause of rubber pneumatic butterfly valves.
Finally, rubber pneumatic butterfly valves are widely used;
To sum up, let's not misunderstand that rubber pneumatic butterfly valves have no damping effect. Assuming that the expected effect is not achieved, it must be that you have not selected the rubber pneumatic butterfly valve that is suitable for you.

What is the difference between high-pressure hose and pneumatic butterfly valve
Difference between high-pressure rubber hose and pneumatic butterfly valve:
According to the manufacturing process, the high-pressure hose is mainly divided into high-pressure steel wire braided hose and high-pressure steel wire wound hose:
High pressure steel wire wound hose The structure of high pressure steel wire wound hose is mainly composed of inner rubber layer, middle rubber layer, four or more layers of alternately wound steel wire reinforcement layer and outer rubber layer.
High pressure steel wire braided hose The structure of high pressure steel wire braided hose is mainly composed of liquid resistant synthetic rubber inner rubber layer, medium rubber layer, I, II, III steel wire braided layer and weather resistant synthetic rubber outer rubber layer.
1 The manufacturing methods of braiding and winding are different. Because the braided steel wire is reticular, the wound steel wire is in the form of roller.
2 The braided layer can be odd layer, while the twined layer must be even layer. Because the twined layer must be clockwise twined on one layer and counterclockwise twined on the other, so that the steel wire will not be loose.
3 For the steel wire with the same number of layers, the winding pressure is greater than the braiding pressure.
Pneumatic butterfly valve uses two kinds of bellows, one is spiral bellows; The other is annular bellows.
Spiral bellows
The spiral corrugated pipe is a pipe shaped shell with spirally arranged corrugations. There is a spiral rising angle between two adjacent corrugations, and all corrugations can be connected through a spiral line.
Connection mode of pneumatic butterfly valve:
The connection mode of pneumatic butterfly valve is divided into flange connection, screw thread connection and quick coupling connection. Small diameter pneumatic butterfly valve generally adopts screw thread and quick coupling connection, while large diameter pneumatic butterfly valve generally adopts flange connection.
The above is related to pneumatic butterfly valve, and I hope it can help you.
