Clamp type quick opening blind plate

Structure characteristics:

1, the blind plate sealing surface and the sealing ring without relative rotation, the sealing ring is not easy to damage, so that the whole system to achieve a better sealing effect.

Three, 2 valve clamp to achieve a lock at the same time action, force uniform, reducing the length of the opening of the screw, so that the switch becomes more flexible and reliable.

3, while increasing the bite force (occlusal area, area of more than 90%), more suitable for large-diameter high-pressure natural gas pipeline, the main pressure parts of blind plate made of integral forging steel 20#16Mn and welding parts, main bearing parts.

4, has the self-locking function (blind self-locking, shockproof, relax, open two times relief), not only to prevent the blind plate in the locking process of loosening, while preventing the dangerous situation of system with pressure to open the blind plate.
