It is a kind of Quick Opening Closure that through the disengaging or banding of hoop realizes
quick open or closed.
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. |

Structure and formulation of lock ring QOC
Locking-ring quick opening closure consists of blind plate cover, barrel flange, integral scalable
locking ring, self-tightening sealing ring, opening structure and safety locking device.
Please check the following detail structure:

It has the function of safety interlocking. When the Quick Opening Closure closed, the safety interlocking can realize positioning. When the Quick Opening Closure opens, the safety interlocking can realize secondary pressure relief. | |
Protect sealing ring. 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. | |
Lcoking Takes multisurface structure. when locking can realize the action, translational contacts and uniform strength. meanwhile, Increasing the occlusal contact areas.The cover and base of blind-plate osslusal contact areas 90% larger than contact size. | |
Using long lead screw transmission. Short time and Flexible characteries of opening and closing. | |
Simple structure. Quick and convenient when open or close. Using LSM structure ensures one operator can open blind plate within one minutes without any special tools. Its safe, convenient and no any leakge. |
