Description

Technical Field

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

[0002] A gate valve, also known as a stop valve, is a type of forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to ensure that the sealing surface does not leak.

[0003] In the existing technology, a shut-off valve for easy and quick disassembly and assembly of pipelines is disclosed in application number CN202321648884.2. This application involves aligning the inner tube of the connecting pipeline with both ends of the valve seat, slowly inserting the inner tube into the valve seat, and allowing the connecting pipeline to abut against the connecting plate. At this time, pressing two moving blocks causes the slide rod to slide in the slide groove, driving the moving blocks to move and bringing the two moving blocks closer together, while simultaneously bringing the two limiting blocks closer together, and the spring is stretched. After the two limiting blocks are inserted into the limiting groove, the moving blocks are released. When the moving blocks lose pressure, the spring deforms again and pulls the two moving blocks away from each other, so that the two limiting blocks are respectively engaged on the two sides of the limiting groove, completing the fixation of the connecting pipeline. However, sometimes the connecting pipeline is installed relatively fixedly and is not easy to move, making it inconvenient to disassemble the shut-off valve from the connecting pipeline, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a gate valve that can be easily replaced and maintained, thereby solving the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a gate valve that can be easily replaced and maintained, comprising a valve body:

[0006] A connecting assembly, which is installed on the left and right sides of the valve body;

[0007] The connection component includes:

[0008] A connecting pipe is fixedly installed on the left and right sides of the valve body. A connecting pipe is attached to the side of the connecting pipe away from the central axis. A limit ring is slidably connected to the outside of the connecting pipe. A fixing plate is fixedly installed on the outside of the connecting pipe. A first rubber pad is adhered to the side of the fixing plate near the central axis. Fixing blocks are fixedly installed at the front and rear ends of the limit ring. A first threaded column is rotatably connected between the fixing blocks.

[0009] By adopting the above technical solution, rotating the nut on the first threaded post causes the limiting ring to slide towards the fixing plate and fit tightly against the fixing plate, thereby achieving the connection between the connecting pipe and the connecting pipeline.

[0010] A further feature of this invention includes:

[0011] A docking component is installed inside the connecting component to improve the stability of the connecting component during use.

[0012] The docking components include:

[0013] A stabilizing ring is fixedly installed inside the connecting pipe. A sleeve is fixedly installed on the side of the stabilizing ring away from the central axis. A push rod is slidably connected inside the sleeve. A connecting ring is fixedly installed on the side of the push rod away from the central axis. A spring is provided between the push rod and the sleeve.

[0014] By adopting the above technical solution, the spring pushes the push rod to slide out of the sleeve, thereby pushing the stabilizing ring to engage in the connecting pipe, ensuring the stability of the connection between the connecting pipe and the butt joint pipe.

[0015] A further feature of this invention includes:

[0016] The control component is installed inside the valve body.

[0017] The control components include:

[0018] A mounting base is snapped into the upper part of the valve body. An adjusting column is threaded inside the mounting base. A sealing block is rotatably connected to the lower end of the adjusting column. A rotating handle is fixedly installed on the upper end of the adjusting column.

[0019] By adopting the above technical solution, rotating the handle drives the adjusting column to slide down in a spiral, thereby pushing the sealing block down and adjusting the size of the connecting holes on the left and right sides inside the valve body, thereby achieving the adjustment of the liquid flow rate.

[0020] A further feature of this invention includes:

[0021] A locking component, which is installed on the outside of the valve body, is used to lock the internal structure of the control component.

[0022] The locking component includes:

[0023] A docking block is fixedly installed on the lower outer side of the mounting base. The lower end of the docking block has a docking groove. An mounting block is fixedly installed on the upper outer side of the valve body. A second rubber pad is adhered to the upper end of the mounting block. A locking block is slidably connected to the upper end of the docking block on the outer side of the mounting base. Limit blocks are fixedly installed on the left and right sides of the locking block. Second threaded columns are fixedly installed at the front and rear ends of the valve body.

[0024] By adopting the above technical solution, rotating the nut on the outside of the second threaded column causes the limit block to slide down, and the locking block follows, thereby squeezing the mating block tightly against the valve body, thus achieving the installation and locking of the control component.

[0025] The beneficial effects of this utility model are:

[0026] The connecting component of this utility model uses a limiting ring and a fixing plate to facilitate the disassembly and installation of the gate valve, making it easier to replace and repair the gate valve and improve work efficiency. At the same time, the docking component uses a push rod and a connecting ring to ensure the stability of the connection between the connecting pipe and the docking pipe, while reducing the probability of leakage at the connection between the docking pipe and the connecting pipe.

[0027] The control component of this utility model cooperates with the adjusting column and the sealing block to adjust the size of the connecting part on both sides inside the valve body, which facilitates the adjustment of the flow rate and velocity of the liquid. At the same time, the locking component cooperates with the mounting block through the docking block, which facilitates the disassembly and assembly of the mounting seat, facilitates the inspection of the inside of the valve body, and improves the service life of the shut-off valve.

[0036] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] Reference Figure 1-6 A gate valve that can be easily replaced and maintained includes a valve body 1, a connecting component 2, a docking component 3, a control component 4, and a locking component 5. The connecting component 2 is installed on the left and right sides of the valve body 1, and the docking component 3 is installed inside the connecting component 2 to improve the stability of the connecting component 2 during use. The control component 4 is installed inside the valve body 1, and the locking component 5 is installed on the outside of the valve body 1 to lock the internal structure of the control component 4.

[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting component 2 includes: a connecting pipe 201 fixedly installed on the left and right sides of the valve body 1; a connecting pipe 202 is attached to the side of the connecting pipe 201 away from the central axis; a limiting ring 203 is slidably connected to the outside of the connecting pipe 201; a fixing plate 204 is fixedly installed on the outside of the connecting pipe 202; a first rubber pad 205 is adhered to the side of the fixing plate 204 near the central axis; fixing blocks 206 are fixedly installed at the front and rear ends of the limiting ring 203; a first threaded post 207 is rotatably connected between the fixing blocks 206; the docking component 3 includes: a stabilizing ring 301 fixedly installed inside the connecting pipe 201; a sleeve 302 is fixedly installed on the side of the stabilizing ring 301 away from the central axis; a push rod 303 is slidably connected inside the sleeve 302; a connecting ring 304 is fixedly installed on the side of the push rod 303 away from the central axis; and a spring 305 is provided between the push rod 303 and the sleeve 302.

[0039] In this invention, when disassembling the shut-off valve from the external pipeline, the nut on the first threaded post 207 is tightened to disengage it from the fixing plate 204. Then, the first threaded post 207 is rotated to disengage it from the slot on the fixing plate 204, releasing the locking of the limiting ring 203. The limiting ring 203 is then slid towards the center to disengage it from the fixing plate 204, releasing it from the first rubber pad 205 on the fixing plate 204. Finally, the shut-off valve is pulled upwards to remove it from the connecting pipeline 202. This facilitates the disassembly and installation of the shut-off valve, making it easier to replace and repair, thus improving work efficiency. When installing between connecting pipelines 202... When the shut-off valve is in operation, it slides down between the connecting pipes 202. The connecting ring 304 has a beveled design on its side. The connecting pipes 202 on both sides squeeze the connecting ring 304 and slide it into the connecting pipe 201, thereby pushing the push rod 303 to slide into the sleeve 302 on the stabilizing ring 301 and compressing the spring 305. When the shut-off valve is installed in the designated position, the spring 305 returns to its original position, pushing the push rod 303 out of the sleeve 302, thereby pushing the connecting ring 304 into the connecting pipe 202. This facilitates the covering of the connection gap between the connecting pipe 202 and the connecting pipe 201, ensuring the stability of the connection between the connecting pipe 202 and the connecting pipe 201, and reducing the probability of leakage at the connection between the connecting pipe 201 and the connecting pipe 202.

[0040] Reference Figure 1 , Figure 4 and Figure 5 The control component 4 includes: a mounting base 401 that is snapped into the upper part of the valve body 1; an adjusting column 402 is threadedly connected inside the mounting base 401; a sealing block 403 is rotatably connected to the lower end of the adjusting column 402; and a rotating handle 404 is fixedly installed on the upper end of the adjusting column 402. The locking component 5 includes: a docking block 501 fixedly installed on the lower part of the outer side of the mounting base 401; a docking groove 502 is opened at the lower end of the docking block 501; a mounting block 503 is fixedly installed on the outer side of the upper end of the valve body 1; a second rubber pad 504 is adhered to the upper end of the mounting block 503; a locking block 505 is slidably connected to the outer side of the mounting base 401 at the upper end of the docking block 501; limit blocks 506 are fixedly installed on the left and right sides of the locking block 505; and second threaded columns 507 are fixedly installed at the front and rear ends of the valve body 1.

[0041] In this invention, when using the shut-off valve, rotating the handle 404 causes the adjusting column 402 to spiral down on the mounting base 401, thereby pushing the sealing block 403 down. This allows the sealing block 403 to adjust the size of the connection between the two sides inside the valve body 1, facilitating the adjustment of the liquid flow rate. When the valve body 1 needs to be disassembled for maintenance, rotating the nut on the second threaded column 507 removes the nut, then sliding the locking block 505 upwards releases the pressure on the docking block 501. Then, pulling up the mounting base 401 causes the limiting block 506 to slide upwards from outside the second threaded column 507, pulling the lower end of the mounting base 401 out of the valve body 1. Simultaneously, the mounting block 503 disengages from the docking groove 502 on the docking block 501, thereby disengaging the second rubber pad 504 from the docking groove 502, thus enabling the disassembly of the mounting base 401. This facilitates the disassembly and assembly of the mounting base 401, makes it easier to inspect the inside of the valve body 1, and improves the service life of the shut-off valve.
