Ensure That The Opening And Closing Action Of The Closing Damper Is Foolproof

The closing baffle door is mainly composed of several parts such as frame, blade, sealing sheet, main shaft, bearing, shaft seal, crank connecting rod mechanism, and actuator (optional). The frame adopts steel plate compression forming, section steel welding forming or casting forming, and the blade adopts steel plate compression forming or casting forming. The streamline blades of the cross section ensure minimal pressure loss of the medium. A special elastic sealing structure is set between the blade and the blade, and between the blade and the frame, to ensure that the sealing rate before and after the blade is closed can reach more than 99%, and the sealing rate can reach more than 99.5% for special orders. The blade and the main shaft are connected by special fasteners. After closing the baffle and installing it on the pipe, any part can be disassembled, and it is guaranteed that the parts can be easily repaired or replaced under working conditions. The journal adopts a special sealing structure and special bearings. The special sealing structure has good sealing performance, no leakage, and high temperature resistance. The special bearings have automatic centering and automatic compensation functions, which can automatically compensate for the coaxial deviation of the front and rear shafts to ensure closure The baffle flap has low resistance, no jams, and flexible rotation. The crank connecting rod mechanism is equipped with special bearings to ensure low transmission resistance. For the giant closing flap doors, a double-arm heavy-duty crank connecting rod mechanism is used to ensure that the opening and closing action of the closing flap flap is foolproof. Manual, electric or pneumatic actuators can be directly connected to the drive spindle or a crank connecting rod mechanism can be used to form a remote transmission. The actuator can also be configured by the user.
