What are the components of double-ball rubber vibration-proof joints
The flexible double-ball rubber shockproof joint is also called rubber soft joint, rubber soft joint, rubber expansion joint, pipe shock absorber, shock absorbing throat and so on. The sphere of this product consists of rubber tube and inner rubber layer, and the reinforcement layer adopts multi-layer scraped nylon cord fabric and outer rubber layer. It is a kind of pipe joint with high elasticity, high air tightness, media resistance and weather resistance. According to different media, different rubber materials are used, such as natural rubber, styrene butadiene rubber, butyl rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on. They are heat-resistant, acid-resistant, alkali-resistant, corrosion-resistant, wear-resistant, oil-resistant, etc., respectively.
 
Scope of application of double sphere rubber vibration-proof joints:
Due to the good comprehensive performance of double sphere rubber vibration-proof joints, they are widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, water supply and drainage, fire fighting and electric power. Double sphere rubber vibration-proof joints connection methods:
Generally there are thread connection, flange connection, clamp connection, etc.
 
Installation method of double sphere rubber vibration-proof joints:
1 . When installing double-ball rubber vibration-proof joints, the installation super displacement must be strictly limited.
2 . Installation bolts should be symmetrical and gradually tightened with pressure to prevent local leakage.
3 . For working pressure above 6MPa, the installation bolts should have elastic pressure pads to prevent the bolts from loosening in the work.
4 . For vertical installation, the joint pipe should be supported by vertical force at both ends, and an anti-pull-off device can be used to prevent the work from being pulled off under pressure.
5 . The installation site should be far from heat source, ozone zone, strict, strong radiation and the use of media that do not meet the requirements of this product.
6 . It is strictly forbidden to use double ball rubber vibration-proof joints during transportation and loading and unloading. Sharp instruments scratch the surface and sealing surface.
