Description

Technical Field

[0001] This utility model relates to the field of engineering valve well technology, specifically to a valve well socket pipe anti-slip structure. Background Technology

[0002] Valve wells are spaces provided for underground pipelines and valves to facilitate opening and closing of sections of the pipeline network or for maintenance work. In valve well pipe connections, socket-type pipes are a commonly used flexible or semi-flexible connection method. The core of this method involves the nesting of a "socket" (the grooved end) and a "spigot" (the protruding end) with a sealing element to achieve the connection. This method offers both ease of installation and resistance to settlement, making it particularly suitable for connecting underground pipelines (such as water supply, drainage, and gas) to valve wells. However, socket-type pipes may slip off at pre-reserved connection points. The anti-slip structure of the socket-type pipe is crucial for ensuring the stable operation of the pipeline system and can be achieved through optimizing the pipe connection structure and properly configuring pipe supports. However, a key challenge is how to construct an anti-slip structure for the socket-type pipe without affecting the connection operations at the pre-reserved ports in the valve well. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-slip structure for the socket pipe of a valve well. By connecting the socket pipe to the well wall of the valve well, an anti-slip structure is constructed while avoiding interference with the pipe connection at the reserved port. To achieve the above objective, this utility model adopts the following technical solution: This utility model discloses a socket pipe anti-slip structure for a valve well. The valve well contains a valve, and at least one side of the valve well has a port. One end of the socket pipe is connected to the valve, and the other end extends from the port and connects to an external pipeline. The socket pipe anti-slip structure for a valve well includes: a first flange, a second flange, a limiting plate, and multiple sets of limiting screw assemblies.

[0004] The first flange is disposed at the end of the valve, and the second flange is disposed at the end of the socket pipe.

[0005] The first flange and the second flange are respectively provided. The limiting plate is inserted into the socket pipe and is fixedly connected to the first flange and the second flange through a connector. One end of the limiting screw assembly is fixed inside the well wall of the valve well, and the other end is connected and locked to the limiting plate.

[0006] The limiting plate is composed of at least two arc-shaped plates assembled together.

[0007] Furthermore, the limiting plate is assembled from two semi-circular annular plates, and the two semi-circular annular plates are evenly provided with multiple inner ring connecting holes and multiple outer ring connecting holes along the circumference. The limiting plate is connected to the first flange and the second flange through a connector on the inner ring connecting hole, and the limiting screw assembly is connected to the outer ring connecting hole.

[0008] In some other embodiments, the limiting plate is integrally formed with the second flange.

[0009] Furthermore, the connecting member comprises a first bolt and a first nut threadedly connected to the first bolt. The limiting screw assembly includes a limiting screw and two nuts threadedly connected to the limiting screw.

[0010] Preferably, the limiting screw is a chemical anchor or an expansion bolt.

[0011] Furthermore, the port is located on one side of the valve well, the well wall on the side where the port is located is the first well wall, and the well wall on the side opposite to the first well wall is the second well wall, and the limiting screw is connected to the first well wall and / or the second well wall.

[0012] In some other embodiments, the valve well is provided with ports and socket pipes on opposite sides, both socket pipes are connected to the valve, and each socket pipe is provided with the socket pipe anti-slip structure of the valve well.

[0013] Preferably, a sealing ring is provided between the socket pipe and the valve. The sealing ring is one of neoprene rubber, EPDM rubber, or nitrile rubber, and the thickness of the sealing ring is 10-30 mm.

[0014] Preferably, the socket pipe is a ductile iron pipe.

Based on the anti-slip structure of the socket pipe, the other end of the socket pipe can extend out of the valve well for pipe connection operation. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Example 1 like Figures 1 to 6As shown, this utility model discloses a socket pipe anti-slip structure for a valve well. A valve 2 is installed inside the valve well 1, and the valve well 1 has a port 11 on at least one side. One end of the socket pipe 3 is connected to the valve 2, and the other end extends from the port 11 and connects to an external pipeline. The socket pipe anti-slip structure for the valve well includes: a first flange 21, a second flange 31, a limiting plate 5, and multiple sets of limiting screw assemblies 6.

[0032] The first flange 21 is located at the end of the valve 2, and the second flange 31 is located at the end of the socket pipe 3.

[0033] The first flange 21 and the second flange 31 are respectively provided. The limiting plate 5 is inserted into the socket pipe 3 and is fixedly connected to the first flange 21 and the second flange 31 through the connector 4. One end of the limiting screw assembly 6 is fixed inside the well wall 12 of the valve well 1, and the other end is connected and locked to the limiting plate 5.

[0034] In this embodiment, the well wall of the valve well 1 on the side of the set port 11 is the first well wall 12A, and the limiting screw assembly 6 is connected to the first well wall 12A.

[0035] The limiting plate 5 is composed of at least two arc-shaped plates assembled together.

[0036] Combination Figure 7 As shown, in this embodiment, the limiting plate 5 is assembled from two semi-circular annular plates, and the two semi-circular annular plates are evenly provided with multiple inner ring connecting holes 51 and multiple outer ring connecting holes 52 along their circumference. The limiting plate 5 is connected to the first flange 21 and the second flange 31 through the connecting piece 4 via the inner ring connecting hole 51, and the limiting screw assembly 6 is connected to the outer ring connecting hole 52. In some other embodiments, the limiting plate 5 and the second flange 31 can also be integrally formed.

[0037] Secondly, in this embodiment, the connecting parts are a first bolt and a first nut threadedly connected to the first bolt. The limiting screw assembly includes a limiting screw and a double nut threadedly connected to the limiting screw, the double nut consisting of a second nut and a third nut. The limiting screw is a chemical anchor, and the connection end between the limiting screw and the well wall 12 is provided with an anchoring adhesive layer (not shown in the figure), and the anchoring adhesive layer is epoxy resin. In some other embodiments, the anchoring adhesive layer may also be vinyl ester resin or unsaturated polyester resin.

[0038] In some other embodiments, the limiting screw can also be an expansion bolt.

[0039] In addition, a sealing ring 7 is provided between the socket pipe 3 and the valve 2, and the socket pipe 3 is a ductile iron pipe. The sealing ring 7 is made of neoprene rubber and has a thickness of 25 mm. In some other embodiments, the sealing ring 7 can also be made of EPDM rubber or nitrile rubber, and the thickness of the sealing ring 7 can be in the range of 10-30 mm.

[0040] Example 2 The difference between Example 2 and Example 1 is that the limiting screw assembly 6 and the well wall 12 connected to the valve well 1 are different.

[0041] like Figures 8 to 10 As shown, in this embodiment, port 11 is located on one side of valve well 1. The well wall 12 on the side where port 11 is located is the first well wall 12A, and the well wall 12 on the opposite side of the first well wall 12A is the second well wall 12B. The limiting screw assembly 6 is connected to the second well wall 12B.

[0042] In some other embodiments, the limiting screw assembly 6 can also be alternately connected to the first well wall 12A and the second well wall 12B, but the structure is relatively complex, the implementation cost is too high, and it will not significantly increase the stability of the structure, so it will not be described in detail here.

[0043] Example 3 The difference between Embodiment 3 and Embodiments 1 and 2 is that: the valve well 1 is provided with multiple ports 11, and the limiting screw assembly 6 at each port 11 is connected to the well wall 12 on the side where the port 11 is located.

[0045] The above description is only a preferred embodiment of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
