Importance of spring and shock absorber
The two major components of the suspension system include spring and pneumatic butterfly valve. The main function of the spring is to play a supporting role. The function of the pneumatic butterfly valve is to reduce the vibration of the spring. It ensures that the car is driven all the time. But the shock absorber is easy to wear. The shock absorber has to be replaced after only 60000 km driving on one side. How do you know when to change the shock absorber? In fact, the most clear signal is the feeling of dizziness when driving. In addition, it is another signal that the car will be stable for a long time after driving over the roadblock.
When encountering this problem, the car owner can do the following tests:
(1) Press down hard on the car shell (part above the wheel).
(2) Then let go. If the car keeps swinging, the shock absorber is worn.
Selection criteria and precautions of shock absorber:
1. Determine the specification and quantity of vibration isolator according to the total amount of vibration isolation system, including the weight of mechanical equipment, base, local pipelines, cables, etc., and the size of the base;
2. The working temperature of the product is - 20 ℃ -+80 ℃, which is not suitable for use in the environment with heavy acid and alkali gas;
3. The load of each shock absorber shall not exceed 20% - 30% of the rated load;
4. When the adjustable pneumatic butterfly valve is installed, if it is found that the unit is not good enough, the bolts can be adjusted to make the unit good enough;
5. If it is not an anti shear damper, maintenance and installation shall be enhanced during unit transportation.

What are the advantages of corrugated pneumatic butterfly valves
Stainless steel wire mesh is made by installing the pneumatic butterfly valve on the main bearing part and maintaining the pressure pipe of the pneumatic butterfly valve. According to the pressure of the pipe and its application, one or more layers of stainless steel wire or steel belt can be selected for weaving. Y According to certain parameters, a high pressure resistant pneumatic butterfly valve is formed. The pressure range of the metal woven hose produced by our company is PN0.6 32 MPa, up to 42 MPa. Stainless steel mesh covers mainly include steel mesh and steel mesh cover.
The maximum allowable expansion per wave is: all high type α within α;= P; 24 mm half height EXPAT and alpha= And PumMn; 12mm. Dust board: dust board shall not be used for wind dust pipe or smoke dust pipe, and dust board shall be used for dust removal. In order to reduce the number of wave joints of bellows, 50% cold drawing shall be considered.
The standard half height corrugated pneumatic butterfly valve is applicable to the situation where the sectional area is less than 4.6 square meters and the flue side is less than 1.5 meters but more than 0.6 mm. Standard full height corrugated pneumatic butterfly valve for the whole chimney.
The corrugated pneumatic butterfly valve has many characteristics, such as excellent flexibility, fatigue resistance, high pressure resistance, high temperature resistance, low temperature resistance, corrosion resistance, etc. Its service life related to other hoses (rubber and plastic hoses) will be much higher, so it has high economic benefits. With the development of modern industry, the demand for high-temperature and high-pressure corrugated hoses is growing.
