Since the production of the first bottom unheading device in 2006. The device is designed for the automatic opening and closing the bottom of coke drum during the coke production.
The flange sealing technology is adopted, and the flange is connected with the hydraulic bolts through the hydraulic cylinder to drive the flatbed unheading device.
The use of elastic loaded metal seat, hard seal design.
The use of single valve plate, double sealing surface, pressure chamber design, simple structure.
Can provide manual, local, remote operation control mode, to meet the functional requirements of on-line intelligent control.
Gas nitriding treatment on sealing surface to prolong service life.
Fully closed operation, reduce the operator labor intensity, improve the working environment.
Valve face to face distance is small (670mm), suitable for smaller installation space.
Atmospheric pressure valve chamber, if there is coke in the chamber, it could be removed online.
Electric and hydraulic drive mechanisms are interchangeable.
