Description

Technical Field

[0001] This utility model belongs to the field of gate valve technology, and in particular relates to a gate valve that is easy to disassemble and assemble. Background Technology

[0002] A gate valve is a shut-off valve that controls the flow of media (such as water, steam, oil, etc.) in a pipeline by the up-and-down movement of a gate. Its core function is to fully open or fully close the fluid, and it features low fluid resistance, low opening force, and unrestricted media flow direction.

[0003] Traditional gate valves are typically installed and fixed to pipelines using multiple bolts. This method is inefficient for both installation and disassembly, and the installation process requires frequent adjustments to the position of the gate valve and the pipeline to align the mounting holes. It also requires two people to work together to insert the bolts and tighten them, making the operation quite complicated. Utility Model Content

[0004] The purpose of this invention is to provide an easily detachable gate valve. The gate valve is connected to the connecting pipe, and the positioning block on the second convex ring is inserted into the positioning groove on the first convex ring to position the gate valve. Then, the fitting is inserted into the connection, and the locking nut is rotated to compress the fitting, thus locking the connection. When disassembly is required, the locking nut is loosened, the fitting is pulled out, and finally, the gate valve is pulled upwards for disassembly. This method allows for quick installation and disassembly, is simple and fast, and can be operated by a single person. It solves the problem of traditional gate valves, which are typically installed and fixed with multiple bolts when connected to pipes. This method is inefficient for both installation and disassembly and requires frequent adjustments to the position of the gate valve and the pipe to align the mounting holes.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an easily detachable gate valve, comprising a gate valve, wherein connecting pipes are provided on both the left and right sides of the gate valve, and a protective shell is fitted over the connection between the gate valve and the connecting pipes, and further comprising:

[0007] A locking mechanism is provided at the connection between a gate valve and a connecting pipe. A first convex ring is provided on the side of the connecting pipe facing the gate valve, and second convex rings are provided on the left and right ends of the gate valve. The locking mechanism includes a kit fitted onto the first and second convex rings. The kit has slots on both the left and right sides. Several threaded shafts are fixedly connected to the sides of the first and second convex rings that are furthest from each other. Locking nuts are threaded onto the threaded shafts. The threaded shafts are all welded onto the first and second convex rings.

[0008] A limiting mechanism is provided at the bottom of the connecting pipe and is used to support the gate valve.

[0009] The kit is U-shaped, and the inner diameter of the slot is slightly larger than the diameter of the threaded shaft.

[0010] Furthermore, a positioning groove is provided on the top of the first convex ring, and a positioning block is fixedly connected to the left side of the second convex ring. The shape of the positioning block is adapted to the positioning groove, and the positioning block is inserted into the positioning groove. Both the positioning groove and the positioning block are square, and their sizes are adapted to each other.

[0011] The positioning block and the positioning groove are used to position the gate valve and the connecting pipe when they are connected.

[0012] Furthermore, the kit is inserted into the threaded shaft through the slot, and after the gate valve is positioned by the positioning block, the threaded shaft on the first convex ring will be in the same straight line as the threaded shaft on the second convex ring.

[0013] Furthermore, the limiting mechanism includes a bracket fixedly connected to the bottom of the connecting pipe. The bracket is U-shaped, and an arc-shaped limiting plate is fixedly connected to the side of the bracket facing the gate valve. The inner arc surface of the arc-shaped limiting plate is adapted to the bottom surface of the gate valve. The bracket is installed on the connecting pipe by welding, and the arc-shaped limiting plate is integrally formed with the bracket.

[0014] The arc-shaped limiting plate and the bracket work together to limit and support the docked gate valve.

[0015] Furthermore, the second convex ring has an annular groove on the side facing the connecting pipe, and a sealing ring is fitted inside the annular groove. After the connecting pipe and the gate valve are connected, the sealing ring will contact the surface of the connecting pipe.

[0016] Furthermore, the protective shell has positioning rings on its inner left and right sides.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 As shown, this utility model is an easily disassembled gate valve, including a gate valve 1, with connecting pipes 11 on both the left and right sides of the gate valve 1, and a protective shell 12 covering the connection between the gate valve 1 and the connecting pipes 11. It also includes:

[0031] Locking mechanism 2 is located at the connection between gate valve 1 and connecting pipe 11. A first convex ring 111 is provided on the side of connecting pipe 11 facing gate valve 1, and second convex rings 13 are provided on the left and right ends of gate valve 1. Locking mechanism 2 includes a kit 21 sleeved on the first convex ring 111 and the second convex ring 13. The kit 21 has slots 24 on both the left and right sides. Several threaded shafts 22 are fixedly connected to the sides of the first convex ring 111 and the second convex ring 13 that are far apart from each other. Locking nuts 23 are threaded onto the threaded shafts 22. Valve 1 is connected to the connecting pipe 11, and the positioning block 131 on the second convex ring 13 is inserted into the positioning groove 112 on the first convex ring 111, thereby positioning the gate valve 1. Then, the fitting 21 is inserted into the connection, and the locking nut 23 is rotated to compress the fitting 21, thus locking the connection. When disassembly is required, the locking nut 23 is loosened, the fitting 21 is pulled out, and finally the gate valve is pulled upwards for disassembly. This method allows for quick installation and disassembly, is simple and fast, and can be operated by a single person.

[0032] The limiting mechanism 3 is located at the bottom of the connecting pipe 11 and is used to support the gate valve 1. The kit 21 is U-shaped and the inner diameter of the slot 24 is slightly larger than the diameter of the threaded shaft 22.

[0033] The top of the first convex ring 111 is provided with a positioning groove 112. The left side of the second convex ring 13 is fixedly connected with a positioning block 131. The shape of the positioning block 131 is adapted to the positioning groove 112. The positioning block 131 is inserted into the positioning groove 112. The positioning block 131 and the positioning groove 112 are used to position the gate valve 1 and the connecting pipe 11 when they are connected.

[0034] The assembly 21 is inserted into the threaded shaft 22 through the slot 24. After the gate valve 1 is positioned by the positioning block 131, the threaded shaft 22 on the first convex ring 111 will be in the same straight line as the threaded shaft 22 on the second convex ring 13.

[0035] The limiting mechanism 3 includes a bracket 31 fixedly connected to the bottom of the connecting pipe 11. The bracket 31 is U-shaped, and an arc-shaped limiting plate 32 is fixedly connected to the side of the bracket 31 facing the gate valve 1. The inner arc surface of the arc-shaped limiting plate 32 is adapted to the bottom surface of the gate valve 1. The arc-shaped limiting plate 32 and the bracket 31 cooperate to limit and support the gate valve 1 when it is connected to the connecting pipe 11. When the gate valve 1 is connected to the connecting pipe 11, the bottom of the gate valve 1 will contact the arc-shaped limiting plate 32 to limit the gate valve 1, so that the gate valve 1 is placed and connected more stably. At the same time, it does not require the staff to continuously support the gate valve 1. This method allows the staff to operate more easily during the installation process.

[0036] The second convex ring 13 has an annular groove 132 on the side facing the connecting pipe 11. A sealing ring 133 is fitted inside the annular groove 132. After the connecting pipe 11 and the gate valve 1 are connected, the sealing ring 133 will contact the surface of the connecting pipe 11.

[0037] The protective shell 12 has positioning rings 14 on both the left and right sides of its inner side. The two positioning rings 14 are fixedly connected to the surface of the connecting pipe 11 and the surface of the gate valve 1, respectively. The positioning rings 14 are used to position the protective shell 12 and push and squeeze the protective shell 12.

[0038] One specific application of this embodiment is:

[0039] In use, first, fit the sealing ring 133 into the annular groove 132 on the second convex ring 13. Then, connect the gate valve 1 to the connecting pipe 11 and insert the positioning block 131 on the second convex ring 13 into the positioning groove 112 on the first convex ring 111. This positions the gate valve 1 without requiring the operator to align the holes. The bottom of the gate valve 1 will contact the arc-shaped limiting plate 32, limiting the gate valve 1 and making it more stable when connected. This also eliminates the need for continuous support from the operator. Next, insert the kit 21 into the threaded shaft 22 on the first convex ring 111 and the second convex ring 13 through the slots 24 on both sides. Finally, use a wrench to turn the locking nut 23 clockwise. The groove 24 will be squeezed, thereby locking and fixing the gate valve 1 and the connecting pipe 11. At this time, the sealing ring 133 is squeezed to achieve a good sealing effect. The other components 21 can be installed and locked in sequence. This method can quickly complete the installation. Finally, the protective shell 12 is put on the connection between the gate valve 1 and the connecting pipe 11, and the inner side of the protective shell 12 will contact the surface of the positioning ring 14, thereby restricting and fixing the protective shell 12. The positioning ring 14 will be tightly attached to the protective shell 12 and will push and deform the protective shell 12 slightly, thereby fixing the protective shell 12 by squeezing. By installing the protective shell 12, when buried in the soil, the soil can be reduced to prevent soil from entering the connection and reduce the corrosion of the connection.

[0040] When the gate valve 1 needs to be disassembled for maintenance and replacement, pull the protective shell 12 upwards to remove it, then loosen the locking nut 23 so that the kit 21 is not squeezed, and then pull the kit 21 out. At this time, the gate valve 1 and the connecting pipe 11 are released. After the kit 21 is completely removed, pull the gate valve 1 upwards to detach it from the connecting pipe 11, thus quickly completing the disassembly. This method is simple and convenient to operate.
