Clamp type quick opening blind

Advantage

1. It has the function of safe self-locking (blind plate self-locking, shockproof, anti-loose, and secondary pressure relief when opening), which not only prevents the blind plate from loosening during the locking process, but also prevents the danger of opening the blind plate when the pressure is re-pressed. The situation happened.
2. The sealing ring and the sealing surface are not rotated, and the sealing ring is not easily damaged, thereby better protecting the sealing system.
3. The external locking ring changes the old blind plate to three-petal type, which realizes simultaneous action and uniform force during locking, which reduces the length of the opening screw and makes the switch more flexible and reliable.
4. At the same time, the area of the bite force is increased. (The occlusal area of the screw-type blind plate is nearly 50%, and the occlusal area of the lock ring type blind plate is more than 90%.) It is more suitable for the high-pressure large-diameter natural gas pipeline.
