What is the qualification of the damping performance of the metal pneumatic butterfly valve
Pneumatic butterfly valves include rubber pneumatic butterfly valves, metal pneumatic butterfly valves, wire rope pneumatic butterfly valves, etc. In previous articles, we introduced more rubber pneumatic butterfly valves. Today, let's talk about metal pneumatic butterfly valves! What determines the shock absorption performance of metal pneumatic butterfly valves?
The shock absorption performance of metal pneumatic butterfly valve shall be verified through the shock absorption test. The vibration reduction experiment usually stops only when the shock absorber is newly designed and manufactured, and it is not necessary to stop the experiment on the shock absorber one by one after mass consumption; Just stop the typing experiment. However, for particularly important shock absorbers, or shock absorbers that need to stop conditioning in the shock absorption test before reaching the technical request, they should be tested one by one. The vibration reduction experiment is better stopped on the whole machine, so the experimental condition is the practical working condition; The vibration reduction experiment can also be stopped on a special vibration reduction test bench, that is, to imitate the practical working conditions, artificially manufacture the vibration source, and compare the difference between the shock absorber without it and the shock absorber installed, so as to evaluate the advantages and disadvantages of the shock absorber.
The failure or damage of the pneumatic butterfly valve will directly affect the ride comfort and comfort of the car, and will also affect the service life of the car parts. Therefore, the inspection and maintenance of pneumatic butterfly valves are also essential. If there is abnormal continuous vibration during the driving of the car, carefully check whether the pneumatic butterfly valve can leak oil, and if it does, clean it up.
Different industrial departments and different machine products have different requirements for vibration. Our company designs different detection methods and selects different detection equipment according to the use of different products, so as to achieve better quality and shock absorption effect.
There are many detection methods for metal pneumatic butterfly valve detection, and we will stop detection according to different products. If you are very interested in our products, you can call us to consult, waiting for your call. Thank you for your reading!

Hose pressure operating range
It is the main pressure bearing part in the pressure pipeline, with compensation function, and also acts as a sheath for the bellows. It is commonly used for the walk pipe with sufficient flexibility, which is equipped in places where vibration is avoided. Its operating temperature range is extremely wide, - 196-600 degrees.
The pressure range is generally PN0.6 － 32.0Mpa, up to 42.0MPa. One or more layers of stainless steel wires or strips can be selected to stop weaving according to the pressure in the pipeline and the application site; The corrosion resistance of the hose can be guaranteed by selecting the appropriate stainless steel brand according to the corrosivity of the medium through the pipe.
Compared with other hoses, metal bellows has a longer service life, good flexibility, fatigue resistance, high pressure resistance, upper and lower temperature resistance, corrosion resistance, etc., and high comprehensive economic benefits.
With the development of modern industry, there is a higher demand for hose performance, such as higher temperature resistance, higher pressure resistance, etc. Why the pneumatic butterfly valve fails?
Cause 1: The wire mesh sleeve is pulled off due to poor welding quality. The wire mesh sleeve is used to maintain the medium pressure of the pneumatic butterfly valve box. Therefore, if the welding quality of the screen sleeve is too poor, the screen sleeve is easily pulled off, and the pneumatic butterfly valve will have no effect. Therefore, strict water pressure and air tightness tests must be stopped before the hose leaves the factory.
Reason 2: The wire mesh was broken due to improper installation. In the process of installation, the problem of faulty welding of steel wire occurred when the welding of bellows, ring and wire mesh sleeve was stopped. After the pneumatic butterfly valve device, due to the uneven stress of the steel wire, under the pressure of the medium, the phenomenon of fracture appears, which forms the failure of the white steel stainless steel pneumatic butterfly valve.
