Technical Field
[0001] This utility model belongs to the technical field of single-drive split-type anti-leakage flat plate valve, and more specifically, it relates to a single-drive split-type anti-leakage flat plate valve. Background Technology
[0002] Valves are control components in conveying systems, used to control the direction, pressure, and flow rate of the medium being conveyed. The main functions of valves include connecting and disconnecting the medium, preventing backflow, regulating medium pressure and flow rate, separating, mixing, or distributing the medium, and preventing the medium pressure from exceeding specified values, ensuring the safe operation of pipelines or equipment.
[0003] Based on the above, the inventors have discovered the following problems:
[0004] Current single-drive split-type anti-leakage flat valves have complex structures and are generally manually driven, making operation quite cumbersome.
[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a single-drive split-type anti-leakage flat valve in order to achieve a more practical value. Utility Model Content
[0006] The purpose and function of this utility model of a single-drive, split-type anti-leakage flat valve are achieved by the following specific technical means:
[0007] A single-drive, split-type anti-leakage flat valve includes a valve body, a mounting box, a rotating shaft, and a hydraulic telescopic rod. The mounting box is located at the upper end of the valve body, and a hydraulic telescopic rod is located on one side of the mounting box. The output end of the hydraulic telescopic rod passes through the mounting box and extends into the mounting box, where a moving component is located. The upper end of the rotating shaft is movably located at the top of the mounting box, and the lower end of the rotating shaft passes through the mounting box and extends into the valve body, where it is movably connected to the bottom end of the valve body. An opening and closing component is located on the rotating shaft, and the upper end of the opening and closing component is connected to the moving component.
[0008] Furthermore, the movable component includes a movable slot, a movable block, a movable frame, a support plate, and a movable frame. The mounting box has movable slots on opposite sides of the hydraulic telescopic rod. The output end of the hydraulic telescopic rod is connected to the movable frame. Movable blocks are provided on both sides of the movable frame. The movable blocks are movably disposed in the movable slots. A support plate is provided on the movable frame on the side away from the movable blocks. A movable frame is provided on the support plate.
[0009] Furthermore, the opening and closing assembly includes a first sleeve shaft, which is sleeved on the rotating shaft. A second sleeve shaft is sleeved on the first sleeve shaft. A right valve is provided on the first sleeve shaft and inside the valve housing. A left valve is provided on the second sleeve shaft and inside the valve housing. A first connector is provided at the upper end of the first sleeve shaft, which penetrates the top of the valve housing. A second connector is provided at the upper end of the second sleeve shaft, which penetrates the top of the valve housing. A first limiting frame is provided on the first connector. A second limiting frame is provided on the second connector. The first and second limiting frames are movably connected to a pair of movable frames, respectively.
[0010] Furthermore, both the left and right valves have a rubber layer at the point where they fit against the inner wall of the valve body.
[0011] Furthermore, a telescopic dust cover is provided between the left valve and the right valve.
[0012] Furthermore, the sleeve shaft two is provided with a sealing element at the contact point with the valve body.
[0013] Furthermore, the surfaces of the left and right valves are provided with an anti-corrosion layer.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] In this invention, by activating the hydraulic telescopic rod to extend, the moving frame moves along the moving groove, causing the relative position of the movable frame to move. This, in turn, moves the first and second limiting frames, causing the first and second connecting pieces to rotate around the axis of the rotating shaft. This causes the first and second sleeve shafts to rotate in the same direction, and the right and left valves to rotate around the central axis of the rotating shaft. When the right and left valves rotate to the same plane, the single-drive split-type anti-leakage plate valve closes. When the right and left valves are close to each other, the single-drive split-type anti-leakage plate valve opens. Operators can easily and conveniently control the opening and closing of the single-drive split-type anti-leakage plate valve by controlling the extension and retraction of the hydraulic telescopic rod, thereby reducing labor costs.
[0016] The design incorporates rubber layers at the points where both the left and right valves contact the inner wall of the valve housing, which enhances the sealing performance between the left and right valves and the inner wall of the valve housing when they are extended to the same plane.
[0017] The design of a telescopic dust cover between the left and right valves can prevent the medium inside the valve body from entering the gap between the left and right valves when the left and right valves are opening and closing, thus avoiding affecting the opening and closing of the left and right valves.
[0018] The design of providing seals at the contact points between the sleeve shaft 2 and the valve body can prevent the medium inside the valve body from entering the mounting box and affecting the operation of the moving components when the sleeve shaft 2 is rotated.
[0019] The design of having anti-corrosion layers on the surfaces of the left and right valves can prevent them from being corroded and oxidized by air, thus extending their service life. Attached Figure Description

[0029] Example:
[0030] As attached Figure 1 To be continued Figure 4 As shown:
[0031] This utility model provides a single-drive split-type anti-leakage flat valve, including a valve body 1, a mounting box 2, a rotating shaft 17, and a hydraulic telescopic rod 3. The mounting box 2 is provided at the upper end of the valve body 1, and the hydraulic telescopic rod 3 is provided on one side of the mounting box 2. The output end of the hydraulic telescopic rod 3 passes through the mounting box 2 and extends into the mounting box 2, where a moving component is provided. The upper end of the rotating shaft 17 is movably located at the top of the mounting box 2, and the lower end of the rotating shaft 17 passes through the mounting box 2 and extends into the valve body 1, where it is movably connected to the bottom end of the valve body 1. An opening and closing component is provided on the rotating shaft 17, and the upper end of the opening and closing component is connected to the moving component.
[0032] The movable component includes a movable slot 9, a movable block 10, a movable frame 20, a support plate 11, and a movable frame 12. The mounting box 2 has movable slots 9 on opposite sides of the hydraulic telescopic rod 3. The output end of the hydraulic telescopic rod 3 is connected to the movable frame 20. Movable blocks 10 are provided on both sides of the movable frame 20. The movable blocks 10 are movably disposed in the movable slots 9. A support plate 11 is provided on the movable frame 20 on the side away from the movable blocks 10. The movable frame 12 is provided on the support plate 11.
[0033] The opening and closing assembly includes a first sleeve shaft 19, which is sleeved on the rotating shaft 17. A second sleeve shaft 18 is sleeved on the first sleeve shaft 19. A right valve 4 is provided on the first sleeve shaft 19 and inside the valve housing 1. A left valve 5 is provided on the second sleeve shaft 18 and inside the valve housing 1. A first connector 14 is provided at the upper end of the first sleeve shaft 19, which passes through the top of the valve housing 1. A second connector 13 is provided at the upper end of the second sleeve shaft 18, which passes through the top of the valve housing 1. A first limiting frame 15 is provided on the first connector 14. A second limiting frame 16 is provided on the second connector 13. The first limiting frame 15 and the second limiting frame 16 are respectively movably connected to a pair of movable frames 12.
[0034] By extending the hydraulic telescopic rod 3, the moving frame 20 moves along the moving groove 9, causing the relative position of the movable frame 12 to move. This, in turn, moves the first limit frame 15 and the second limit frame 16, causing the first connector 14 and the second connector 13 to rotate around the axis of the rotating shaft 17. This causes the first sleeve shaft 19 and the second sleeve shaft 18 to rotate in the same direction, and causes the right valve 4 and the left valve 5 to rotate around the central axis of the rotating shaft 17. When the right valve 4 and the left valve 5 rotate to the same plane, the single-drive split-type anti-leakage plate valve closes. When the right valve 4 and the left valve 5 come close to each other, the single-drive split-type anti-leakage plate valve opens. Operators can easily and conveniently control the opening and closing of the single-drive split-type anti-leakage plate valve by controlling the extension and retraction of the hydraulic telescopic rod 3, thereby reducing labor costs.
[0035] Both the left valve 5 and the right valve 4 have a rubber layer 8 at the point where they fit against the inner wall of the valve body 1;
[0036] By incorporating a rubber layer 8 at the contact points between the left valve 5 and the right valve 4 and the inner wall of the valve housing 1, the sealing performance between the left valve 5 and the right valve 4 and the inner wall of the valve housing 1 can be increased when the left valve 5 and the right valve 4 are extended to be on the same plane.
[0037] A telescopic dust cover 21 is provided between the left valve 5 and the right valve 4;
[0038] By providing a telescopic dust cover 21 between the left valve 5 and the right valve 4, the medium inside the valve body 1 can be prevented from entering the gap between the left valve 5 and the right valve 4 when the left valve 5 and the right valve 4 are opening and closing, thus preventing the opening and closing of the left valve 5 and the right valve 4 from being affected.
[0039] Among them, the sleeve shaft 18 and the valve body 1 are both provided with sealing elements at the contact points;
[0040] By providing seals at the contact points between the sleeve shaft 18 and the valve body 1, the medium inside the valve body 1 can be prevented from entering the mounting box 2 and affecting the operation of the moving components when the sleeve shaft 18 is rotated.
[0041] The left valve 5 and the right valve 4 are provided with anti-corrosion layers on their surfaces;
[0042] The design of the anti-corrosion layer on the surface of the left valve 5 and the right valve 4 can prevent the left valve 5 and the right valve 4 from being corroded and oxidized by the air, thus extending the service life of the left valve 5 and the right valve 4.
[0043] The specific usage and function of this embodiment are as follows:
[0044] In this invention, by extending the hydraulic telescopic rod 3, the movable frame 20 moves along the movable groove 9, causing the relative position of the movable frame 12 to move. This, in turn, moves the first limiting frame 15 and the second limiting frame 16, causing the first connecting piece 14 and the second connecting piece 13 to rotate around the axis of the rotating shaft 17. This causes the first sleeve shaft 19 and the second sleeve shaft 18 to rotate in the same direction, and causes the right valve 4 and the left valve 5 to rotate around the central axis of the rotating shaft 17. When the right valve 4 and the left valve 5 rotate to the same plane, the single-drive split-type anti-leakage plate valve closes. When the right valve 4 and the left valve 5 come close to each other, the single-drive split-type anti-leakage plate valve opens. Operators can easily and conveniently control the opening and closing of the single-drive split-type anti-leakage plate valve by controlling the extension and retraction of the hydraulic telescopic rod 3, thereby reducing labor costs.
