Wheel type quick opening blind plate

Wheel pulp type fast opening blind plate is our company's exclusive patented products.

1) with safety interlock function. Close can be achieved when positioning, can be achieved when the two unloading pressure.

2) using multi head screw drive. Switching time is short and flexible.

3) protect the sealing ring. The coaxial double plate structure is adopted, and the sealing ring and the sealing surface have no relative rotation, the sealing ring is not easy to damage, and the sealing surface is not easy to be worn by the impurities.

4) the structure is simple and clear, open and close quickly and conveniently. The wheel type structure ensures that a blind plate is opened in one minute without any special tools, and is safe, convenient and free from leakage.
