Description

Technical Field

[0001] This utility model relates to the field of flat plate valve technology, specifically a flat plate valve with a support component. Background Technology

[0002] Flat plate valves, as a common pipeline control element, are widely used in various fluid transport systems. Their core working principle lies in the opening and closing of the pipeline through the rising and falling movement of the valve plate within the valve chamber, thereby controlling the flow of the medium. A typical flat plate valve mainly consists of a valve body, valve plate, valve seat, and an operating mechanism (such as a handwheel, gearbox, or actuator) that drives the valve plate.

[0003] In existing technologies, during the actual installation of flat valves, in order to ensure that the connection ports at both ends can be precisely aligned with the pipe ports to be connected and fixedly connected, it is usually necessary to adjust the installation height appropriately. Currently, common practices include temporarily placing objects such as wooden boards or bricks under the flat valve as supports to raise the valve body to the required height; or having the operator directly lift the flat valve body and manually adjust its position to align with the pipe port to complete the installation.

[0004] However, existing support installation methods have certain limitations. Relying on wooden planks or bricks to support the valve body often requires operators to repeatedly move and stack materials to match the required pipe height, limiting operational efficiency and making it difficult to guarantee the stability of the support structure. Furthermore, manually lifting heavy valve bodies for height adjustment and connection places high demands on the operator's physical strength, poses potential safety hazards, and is difficult to sustain for extended periods. Utility Model Content

[0005] The purpose of this invention is to provide a flat plate valve with a support component to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flat plate valve with a support assembly, comprising: a valve body, a set of relatively movable flat plates arranged on both sides of the bottom of the valve body, one end of the upper surface of the flat plate being fixedly connected to the bottom of an L-shaped plate, the top of the L-shaped plate being fixedly connected to a support clamp, and one end of the lower surface of the flat plate being connected to a first driving assembly for driving the relative movement of the flat plates.

[0007] The flat plate is slidably mounted on the upper surface of the vertically movable lifting plate. Guide grooves are provided on both sides of the lifting plate. The guide grooves are slidably connected to the guide strips that are fixedly connected to the inner side wall of the support frame. Second drive components for driving the lifting plate to move up and down are connected to both sides of the lifting plate.

[0008] Preferably, the first drive assembly includes a worm gear, with both ends of the worm gear rotatably sleeved in a set of support seats fixedly connected to the lower surface of the lifting plate. One side of the worm gear meshes with a worm wheel for transmission, and the worm wheel is fixedly connected to the bottom of the drive shaft.

[0009] Preferably, the top of the drive shaft passes through the lifting plate and is fixedly connected to the middle of the rotating plate via a connecting bearing. Both ends of the rotating plate are rotatably connected to one end of a connecting rod via connecting pins, and the other end of the connecting rod is rotatably connected to the plate via a fixing pin.

[0010] Preferably, the lower surface of the flat plate is slidably connected to the upper surface of the lifting plate via a slider that is fixedly installed, and a first handwheel is fixedly sleeved on one end of the worm gear.

[0011] Preferably, the second drive assembly includes a threaded rod, which is threadedly sleeved on one side of the lifting plate, and the other side of the lifting plate is slidably sleeved on the limiting rod. The threaded rod is rotatably sleeved in the limiting seat fixedly installed on the support frame, and the bottom end of the limiting rod is fixedly connected to the support frame.

[0012] Preferably, a second handwheel is fixedly sleeved at the bottom of the threaded rod, and an anti-slip arc plate is provided on one side of the second handwheel.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a flat plate valve with a support assembly, comprising: a valve body 1, a set of relatively movable flat plates 2 arranged on both sides of the bottom of the valve body 1, the two flat plates 2 can move towards each other or away from each other, one end of the upper surface of the flat plate 2 is fixedly connected to the bottom of an L-shaped plate 3, the top of the L-shaped plate 3 is fixedly connected to a support clamp 4, one end of the lower surface of the flat plate 2 is connected to a first driving assembly for driving the relative movement of the flat plates 2, the flat plates 2 are slidably mounted on the upper surface of a vertically movable lifting plate 5, the two side walls of the lifting plate 5 are provided with guide grooves 6, the guide grooves 6 are slidably connected to guide strips 8 fixedly connected to the inner side wall of a support frame 7, the guide strips 8 slide in the guide grooves 6, thereby driving the lifting plate 5 to move up and down, and the two sides of the lifting plate 5 are connected to a second driving assembly for driving the lifting plate 5 to move up and down.

[0021] In use, the valve body 1 is placed between the two support frames 7. Driven by the first drive assembly, the two flat plates 2 move relative to each other, thereby driving the L-shaped plate 3 to move synchronously. The L-shaped plate 3 then drives the support clamp 4 to move closer to the side walls of the valve body 1 until it is in close contact with the side walls of the valve body 1, thus quickly fixing the valve body 1 in place. When it is necessary to adjust the height of the valve body 1, the second drive assembly drives the lifting plate 5 to slide in the cooperation of the guide groove 6 and the guide bar 8, thereby causing the lifting plate 5 to lift the valve body 1, thereby adjusting the height of the valve body 1, facilitating the connection of external pipelines and improving the installation flexibility of the valve body 1.

[0022] Example 2: Based on Example 1, the first drive assembly includes a worm gear 9. Both ends of the worm gear 9 are rotatably sleeved in a set of support seats fixedly connected to the lower surface of the lifting plate 5. The support seats provide limiting support for the worm gear 9, thereby improving its rotational stability. One side of the worm gear 9 meshes with a worm wheel 10 for transmission. The worm wheel 10 is fixedly connected to the bottom of the transmission shaft 11. The top end of the transmission shaft 11 passes through the lifting plate 5 and is fixedly connected to the middle of the rotating plate 12 through a connecting bearing. The transmission shaft 11 is rotatably sleeved at the center of the lifting plate 5. Both ends of the rotating plate 12 are rotatably connected to one end of a connecting rod 13 through connecting pins. The other end of the connecting rod 13 is rotatably connected to a plate 2 through a fixed pin. The lower surface of the plate 2 is slidably connected to a slide rail 15 fixedly connected to the upper surface of the lifting plate 5 through a fixedly installed slider 14. The slide rail 15 guides and limits the slider 14. A first handwheel 17 is fixedly sleeved on one end of the worm gear 9.

[0023] When the valve body 1 needs to be initially fixed and installed, place the valve body 1 between the two support clamps 4. First, turn the first handwheel 17. The first handwheel 17 drives the worm 9 to rotate. The worm 9 meshes with the worm wheel 10, causing the worm wheel 10 to drive the transmission shaft 11 to rotate. The transmission shaft 11 then drives the rotating plate 12 to rotate. The rotating plate 12 then pulls the plate 2 to move through the connecting rod 13 rotatably connected to its two ends. The plate 2 moves towards each other under the guidance and limitation of the slide rail 15 and the slider 14. Then, the plate 2 drives the support clamps 4 fixedly connected to the L-shaped plate 3 to move relative to each other, so that the support clamps 4 clamp the two side walls of the valve body 1, thereby completing the quick installation and fixing of the valve body 1.

[0024] Example 3: Based on Example 2, the second drive assembly includes a threaded rod 16, which is threadedly sleeved on one side of the lifting plate 5. The other side of the lifting plate 5 is slidably sleeved on a limiting rod 18. The limiting rod 18 further limits and supports the movement of the lifting plate 5. The threaded rod 16 is rotatably sleeved in a limiting seat fixedly installed on the support frame 7. The limiting seat limits and supports the threaded rod 16. The bottom end of the limiting rod 18 is fixedly connected to the support frame 7. The bottom end of the threaded rod 16 is fixedly sleeved with a first... The second handwheel 19 has an anti-slip arc plate 20 on one side. The arc surface of the anti-slip arc plate 20 is adapted to the outer ring surface of the second handwheel 19. Several anti-slip rubber strips are fixedly connected to the anti-slip arc plate 20 near the side wall of the second handwheel 19. The anti-slip arc plate 20 is fixedly connected to one end of the T-shaped rod 21. The anti-slip arc plate 20 is slidably connected to the groove opened in the inner side wall of the support frame 7. One outer side wall of the support frame 7 is fixedly connected to the end of the T-shaped rod 21 away from the anti-slip arc plate 20 by a spring 22.

[0025] When the height of valve body 1 needs to be adjusted, in the initial state, the anti-slip arc plate 20 is attached to the outer ring surface of the second handwheel 19. Pulling the T-shaped rod 21 outward causes the T-shaped rod 21 to pull the spring 22 outward, thereby driving the anti-slip arc plate 20 into one end of the groove opened in the side wall of the support frame 7, thus releasing the limit on the second handwheel 19. By twisting the second handwheel 19, the second handwheel 19 drives the threaded rod 16 to rotate. Since the threaded rod 16 is threadedly connected to the lifting plate 5... This will drive the lifting plate 5 to move. The lifting plate 5 moves under the limiting guide of the limiting rod 18, and then the lifting plate 5 moves up and down in the support frame 7 through the cooperation of the guide bar 8 and the guide groove 6, thereby adjusting the height of the valve body 1. After adjusting to the appropriate height, the T-shaped rod 21 is released. Under the reverse elastic force of the spring 22, the T-shaped rod 21 will drive the anti-slip arc plate 20 to abut against the outer ring surface of the second handwheel 19, thereby limiting the second handwheel 19 and preventing it from rotating randomly.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
