| Clamp type QOC characters | |
Have the function of secure self-locking (blind plate self-locking,shock proof, anti-looseness. secondary relief ). Its not only prevent blind plate loose during the locking but also avoid the dangerous happen when open the blind plate under the pressure. | |
Taking coaxial double structure, Between the sealing ring and sealing surface without relative rotation. the sealing ring is not easy to damage. the sealing surface is not easy wear by impurities. | |
Triple clamp can realize action at the same time and uniform strength . Reduced the open screw transmission length, make the switch more flexible and reliable. | |
| Above 90% occlusal contact areas , its suitable for high pressure and large diameter natural gas pipeline. the pressure parts take 20# or 16Mn forged steel and main parts no weld assembly. |
