Description

Technical Field

[0001] This utility model relates to the field of flat gate valve technology, and in particular to a flat gate valve that can be quickly disassembled and repaired. Background Technology

[0002] A flat gate valve is a type of valve that controls the opening and closing of pipeline media through the linear lifting and lowering motion of a flat gate. In pipeline systems, flat gate valves are key components for controlling fluid flow and are usually connected to pipelines via flanges.

[0003] Currently, when sealing and installing a flat gate valve to a pipeline, workers need to continuously and manually support the valve and align its flange with the pipeline. However, this installation method not only increases the workload of workers, but also makes the valve position prone to shift due to factors such as fatigue from prolonged manual support, especially in confined spaces, thus affecting the actual installation efficiency. Therefore, to solve this problem, designing a flat gate valve that can be quickly disassembled and repaired is something we need to consider. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a flat gate valve that can be quickly disassembled and repaired. To address usage issues, it is equipped with multiple positioning mechanisms. By controlling the movement of the positioning blocks, in conjunction with the rotating shaft, spring, and mounting holes, the flange and pipeline can be easily positioned and fitted together, improving installation efficiency. Furthermore, no manual support is required for the gate valve body during installation and subsequent disassembly, reducing the actual workload.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flat gate valve capable of rapid disassembly and maintenance includes a gate valve body, with flanges on both the front and rear sides of the gate valve body, and multiple mounting holes on each flange; multiple positioning mechanisms, each positioning mechanism including a fixing block fixedly connected to the side wall of the gate valve body, a columnar connecting rod extending through the fixing block, a pressing block fixedly connected to one end of the columnar connecting rod, a rotating shaft rotatably connected to the other end of the columnar connecting rod, and a positioning block fixedly connected to the other end of the rotating shaft.

[0007] Preferably, each of the cylindrical connecting rods is slidably connected to a corresponding fixed block.

[0008] Preferably, each pressing block is elastically connected to its corresponding fixing block by a spring.

[0009] Preferably, each of the positioning blocks is a U-shaped rod.

[0010] Preferably, a valve stem is rotatably mounted on the upper end of the gate valve body, and a handwheel is fixedly connected to the upper end of the valve stem.

[0011] Preferably, each of the positioning blocks mates with a corresponding mounting hole.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] Multiple positioning mechanisms are set up. By pressing the pressing block, the positioning block is moved, and then the positioning block is rotated to pass through the connection hole and installation hole on the pipeline. With the help of the spring, the flange and the pipeline can be easily fitted and pre-positioned, so that there is no need to align the installation hole during subsequent installation, which facilitates quick installation. At the same time, there is no need to hold the gate valve body during installation and subsequent disassembly, which effectively reduces the actual loading and unloading workload. The overall operation is convenient, efficient and practical. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A flat gate valve that can be quickly disassembled and repaired includes a gate valve body 1. Flanges 2 are provided on both the front and rear sides of the gate valve body 1. Multiple mounting holes 3 are provided on both flanges 2. By using multiple bolts to pass through the corresponding mounting holes 3 and the connection holes on the pipeline, and with the help of nuts, a stable connection between the flanges 2 and the pipeline can be achieved. A valve stem 4 is rotatably provided on the upper end of the gate valve body 1, and a handwheel 5 is fixedly connected to the upper end of the valve stem 4.

[0021] It also includes multiple positioning mechanisms. The positioning mechanism includes a fixed block 6 fixedly connected to the side wall of the gate valve body 1. A columnar connecting rod 7 is provided through the fixed block 6. The columnar connecting rod 7 is slidably connected to the fixed block 6. A pressing block 8 is fixedly connected to one end of the columnar connecting rod 7. The pressing block 8 and the fixed block 6 are elastically connected by a spring 11. The spring 11 can improve the stability of the positioning block 10 when pre-positioning the pipeline and flange 2.

[0022] The other end of the cylindrical connecting rod 7 is rotatably connected to a rotating shaft 9, and the other end of the rotating shaft 9 is fixedly connected to a positioning block 10. The rotating shaft 9 ensures the rotation of the positioning block 10. The positioning block 10 is a U-shaped rod that mates with the corresponding mounting hole 3. After one end of the pipe is fitted to the flange 2 and all the mounting holes 3 are aligned with the connection holes on the pipe, the corresponding positioning block 10 is moved by moving the pressing block 8. Then, the positioning block 10 is rotated so that its outer side aligns with the connection hole on the pipe. Subsequently, the pressing block 8 is released, and with the elastic force of the spring 11, the outer side of the positioning block 10 can penetrate the connection hole and the mounting hole 3 on the pipe, thereby achieving the pre-positioning between the flange 2 and the pipe (e.g., Figure 4 (as shown), so that subsequent installation operations can be performed.

[0023] In this utility model, during use, firstly, one end of the pipe is fitted with the front flange 2, aligning the multiple mounting holes 3 on the flange 2 with the connection holes on the pipe. Then, the right front pressing block 8 is pressed, causing the corresponding cylindrical connecting rod 7, rotating shaft 9, and positioning block 10 to move forward synchronously to the bottom. At this time, the spring 11 will be compressed. Then, the positioning block 10 is rotated so that its outer side aligns with the connection hole on the pipe. Subsequently, the pressing block 8 is released. Under the elastic force of the spring 11, the outer side of the positioning block 10 will sequentially penetrate the connection hole and mounting hole 3 on the pipe, and the inner side of the positioning block 10 will abut against the pipe. This completes the initial pre-positioning between the front flange 2 and the pipe. Similarly, referring to the above operation, the outer side of the left front positioning block 10 is controlled to sequentially penetrate the corresponding connection hole and mounting hole 3 on the pipe, thus achieving a stable pre-positioning between the front flange 2 and the pipe. At this time, the multiple mounting holes 3 on the flange 2 will align with the connection block on the pipe, and the flange 2 will be stably fitted with one end of the pipe (e.g., Figure 4 (as shown)

[0024] After completing the above operations, the flange 2 on the rear side can also be pre-positioned and connected to another pipe. After all the pre-positioning operations are completed, the staff can use multiple bolts and nuts to complete the stable connection between the two flanges 2 and the corresponding pipes. In this way, before installing the gate valve body 1 and the pipe, the flange 2 and the pipe can be conveniently fitted and pre-positioned by using multiple positioning mechanisms. This allows the staff not to align the mounting hole 3 again during the subsequent installation process, and not to continuously hold the gate valve body 1 by hand, which effectively reduces the workload during installation and allows for quick installation operations in the future.

[0025] It is worth mentioning that when disassembly is required, first remove multiple bolts and nuts in sequence. After all bolts and nuts are removed, press all pressing blocks 8 in sequence to release the corresponding positioning blocks 10 from the pre-positioned flange 2 and pipeline, thus completing the disassembly operation. During the entire disassembly process, the staff does not need to hold the gate valve body 1 by hand, which reduces the actual disassembly workload and improves the disassembly efficiency.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
