Telescopic device
The expansion device is composed of expansion seat, sealing ring, expansion pipe, etc., which can be expanded and retracted within a certain range to reach the connection length required on site, and also can overcome the offset caused by different shaft butt joint of pipeline within a certain angle range, which can greatly facilitate the installation and disassembly of valve pipeline.
1. The valve body adopts full channel and streamline design, with small fluid resistance and large flow rate.
2. The joint of body, cover and piston rod is double sealed by sealing gasket and sealing ring without leakage.
3. Double guide of valve body, piston cylinder and piston ensures stable and reliable movement.
4. All stainless steel piston cylinder, integral casting piston and NBR sealing ring. Perfect combination greatly prolongs service life.
5. The detachable valve seat with advanced technology has ingenious structure, novel conception and convenient maintenance and replacement.
6. For the piston cylinder with guide hole, properly increase the resistance to make the piston movement more stable.
