Problems solved by technology

[0002] Vacuum-sealed valves are generally composed of two parts: a valve box and a valve plate; the currently used vacuum-sealed valve plate is a single structure, and the vacuum-sealed valve uses the movement of the valve plate in the valve box to achieve vacuum isolation and sealing; the current vacuum-sealed valve And its sealing method will face the shortcomings of large movement distance of the valve plate and long travel time in the large diameter vacuum sealing valve, which is difficult to meet the requirements of fast sealing

Embodiment 1

[0018] Such as figure 1 , 2 As shown, a fast sealing vacuum valve plate structure includes a sealing moving plate 2 and a sealing static plate 1, the sealing static plate 1 is installed in the vacuum valve box, and the surrounding area of ​​the sealing static plate 1 and the vacuum valve box are For vacuum sealing, a certain number of rectangular diversion holes 3 are opened on the sealed static plate 1, and the surroundings of the diversion holes 3 on the side of the sealed static plate 1 facing the sealed movable plate 2 are vacuum sealing surfaces; the sealed movable plate 2 is installed in a vacuum In the valve box, it can slide left and right on the sealed static plate 1. There are a certain number of rectangular guide holes 4 on the sealed movable plate 2. The number of guide holes 4 is the same as that of the guide holes 3 on the sealed static plate 1. The quantity is the same, and the middle position of each diversion hole 4 on the side of the sealing moving plate 2 f...

Embodiment 2

[0020] Such as image 3 , 4 As shown, the sealing moving plate 2 and the sealing static plate 1 adopt a circular structure, and the flow guide holes 3 and 4 of the sealing static plate 1 and the sealing moving plate 2 are made into a circular distribution, and the structure is symmetrical about the center of the circle, and the sealing moving plate 2 passes through The transmission mechanism rotates on the sealed static plate 1. When the diversion hole 4 on the sealed movable plate 2 coincides with the diversion hole 3 on the sealed static plate 1, the vacuum valve diversion channel is opened; when the sealed movable plate 2 slides When the positions of the sealing groove and the diversion hole 3 on the sealing static plate 1 coincide, the diversion channel of the vacuum valve realizes the closed state.

Abstract

The invention discloses a valve plate structure for a quick sealing vacuum valve. The valve plate structure comprises a sealing moveable plate and a sealing static plate, wherein the sealing static plate is mounted in a valve box of the vacuum valve; the space between the periphery of the sealing static plate and the valve box of the vacuum valve is vacuum-sealed; a certain quantity of first rectangular flow-guiding holes are formed in the sealing static plate; vacuum sealing surfaces are arranged on the periphery of the first rectangular flow-guiding holes in one side, facing to the sealing moveable plate, of the sealing static plate; the sealing moveable plate is mounted in the valve box of the vacuum valve and can slide left and right on the sealing static plate; a certain quantity of second rectangular flow-guiding holes are formed in the sealing moveable plate; the quantity of the second flow-guiding holes is equal to the quantity of the first flow-guiding holes; sealing slots are respectively formed in the middle parts on the certain sides of the second flow-guiding holes in one side, facing to the sealing static plate, of the sealing moveable plate; sealing rings are mounted on the sealing slots. A double-valve plate structure is adopted by the invention, the moving distance of a vacuum valve plate is effectively reduced under the condition of realizing the same area of the flow-guiding holes, and the corresponding action time of the vacuum valve is shortened.

Description

technical field [0001] The invention relates to the field of vacuum sealing valve structure, in particular to a fast sealing vacuum valve plate structure. Background technique [0002] Vacuum-sealed valves are generally composed of two parts: a valve box and a valve plate; the currently used vacuum-sealed valve plate is a single structure, and the vacuum-sealed valve uses the movement of the valve plate in the valve box to achieve vacuum isolation and sealing; the current vacuum-sealed valve And its sealing method will face the shortcomings of large movement distance of the valve plate and long travel time in the large diameter vacuum sealing valve, and it is difficult to meet the requirements of fast sealing. Contents of the invention [0003] The invention provides a fast sealing vacuum valve plate structure, which can effectively reduce the moving distance of the valve plate and improve the sealing speed of the vacuum sealing valve. [0004] The technical scheme adopte...
