Ball joint

Product Overview

The ball joint is mainly suitable for pipe connection with large ground settlement, large vibration and complex terrain.After being installed on the pipe, the ball can rotate freely within the range of 8 angles with rotation * to compensate the deflection caused by foundation settlement and thermal expansion and cold contraction.It has the advantages of large compensation amount, small space occupied, small fluid resistance, easy installation and low comprehensive cost.

Structural characteristics

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.
