Abstract

The invention discloses a slope double-seal vacuum stop valve structure, which relates to the technical field of vacuum stop valves, and comprises a valve body and a connecting shell, and a sealing mechanism penetrating into a sealing stop block is arranged on the outer wall of the sealing stop block and the output end of an air cylinder. By arranging the sealing mechanism, the output end of the air cylinder pushes the sealing piston block to drive the sealing check block to move downwards, when the sealing check block plugs the interior of the valve body, the first spring pushes the fixing rod to reset, the fixing rod is inserted into the fixing hole, the sealing check block is fixed to the connecting shell, and meanwhile the fixing rod is separated from the sealing piston block; then the output end of the air cylinder continues to push the sealing piston block to move in the sealing bin, and air in the sealing bin is conveyed into the first air bag through a first air guide pipe and conveyed into the second air bag through a second air guide pipe; and the first air bag and the second air bag are expanded to block the gaps of the contact parts of the sealing check block, the valve body and the connecting shell, so that the overall sealing performance of the device is improved.

Description

technical field [0001] The invention relates to the technical field of vacuum cut-off valves, in particular to a structure of a slanted double-sealed vacuum cut-off valve. Background technique [0002] Vacuum globe valve is a relatively new type of gate valve. It has some unique advantages of its own structure, such as no friction on the switch, less wear and tear on the seal, and small opening and closing torque, which can reduce the size of the actuator. The multi-turn electric actuator can realize the adjustment and strict shut-off of the medium. [0003] The existing vacuum globe valve generally connects the sealing ring through the outer wall of the movable seal, intercepts the inside of the vacuum globe valve through the movable seal, and then seals the surrounding of the movable seal through the sealing ring, but the sealing ring is used for a long time. It is easy to cause wear and tear during the process, resulting in poor overall sealing of the device, so that the...
