The rubber soft joint is composed of fabric reinforced rubber parts and flat joints, metal flanges or threaded pipe flanges. It is used for vibration isolation, noise reduction and displacement compensation of pipes.
Rubber soft joint has the advantages of reducing pipe noise, good sealing, light weight, convenient installation and maintenance, long service life and so on.
The rubber soft joint can solve all kinds of pipe migration through the mouth, axial expansion and different concentricity role, its use is commonly used in civil construction water supply and drainage engineering, fire pipe network pump room unit pipeline to undertake, sewage treatment pipeline connection, high pressure gas liquefaction medium transport, petroleum, ships and so on.
1. The valve body adopts full channel and streamlined design, with small fluid resistance and large flow rate.
2. The joint of body, cover and piston rod is sealed by sealing gasket and sealing ring with no leakage.
3. Valve body, piston cylinder, piston double guide, smooth and reliable movement.
4. All stainless steel piston cylinder, monolithic cast piston, NBR sealing ring.The perfect combination greatly extends the service life.
5. Removable valve seat with advanced technology, with clever structure, novel conception and convenient maintenance and replacement.
6. The piston cylinder with diversion holes can increase the resistance properly to make the piston motion more stable.
