Description

Technical Field

[0001] This utility model relates to the field of steel wire mesh reinforced pipe technology, and more specifically, to a steel wire mesh reinforced pipe assembly structure. Background Technology

[0002] Steel wire mesh reinforced pipe, also known as steel wire mesh reinforced polyethylene composite pipe, is a composite pipe that uses high-strength steel wire mesh as a reinforcing skeleton, with high-density polyethylene as the matrix for the inner and outer layers, and is firmly bonded together by high-performance hot melt adhesive. In the existing technology, flanges are usually used for bolting, or a pair of detachable clamping or snap-fit ​​structures are used for connection.

[0003] For example, the patent with announcement number CN116972239A discloses a steel wire mesh reinforced pipe and its connection structure. Specifically, it uses upper and lower arc-shaped clamps to externally clamp the connection points at the ends of the pipe sections. However, since the steel wire mesh reinforced pipe has a multi-layer structure, its ends are extremely susceptible to influence, causing the layers to separate and fall off, such as in cases of media penetration and corrosion, alternating pressure impacts inside the pipe, or external extrusion. Therefore, even if clamps are only applied to the connection points of the pipe sections, there is still a situation where the layers of the pipe section gradually begin to fall off from the end connection points, thereby shortening the service life.

[0004] Based on the above description, there is an urgent need for a steel wire mesh skeleton tube assembly structure that can provide a stable connection and ensure that each layer is not easily detached. Utility Model Content

[0005] The purpose of this utility model is to provide a steel wire mesh reinforced pipe assembly structure, which aims to solve the technical problem that the existing clamp-connected steel wire mesh reinforced pipe structure still has the problem of the pipe sections separating from the connection point, resulting in a shortened service life.

[0006] The embodiments of this utility model are achieved through the following technical solutions: A steel wire mesh reinforced pipe assembly structure includes a first ring cover and a second ring cover; a first limiting groove is provided at the end of the first ring cover away from the second ring cover; a second limiting groove is provided at the end of the second ring cover away from the first ring cover; the first ring cover is connected to the second ring cover through a connecting component.

[0007] Preferably, the first ring cover extends to the end away from the second ring cover and is provided with a first elastic ring piece and a second elastic ring piece; the first elastic ring piece and the second elastic ring piece are disposed at the groove end of the first limiting groove and form a first annular groove communicating with the first limiting groove.

[0008] Preferably, the radial width of the first annular groove is smaller than the radial width of the first limiting groove; a first buffer washer is provided inside the first limiting groove.

[0009] Preferably, the second ring cover extends away from the first ring cover and is provided with a third elastic ring piece and a fourth elastic ring piece; the third elastic ring piece and the fourth elastic ring piece are provided at the groove end of the first limiting groove and form a second annular groove communicating with the second limiting groove; the radial groove width of the second annular groove is smaller than the radial groove width of the second limiting groove; a second buffer washer is provided in the second limiting groove.

[0010] Preferably, the cross-section of the second buffer washer is U-shaped.

[0011] Preferably, the connecting assembly includes a first flange and a second flange screwed to the first flange; the first flange is disposed on the outer side wall of the first ring cover; the second flange is disposed on the outer side wall of the second ring cover.

[0012] Preferably, the first ring cover has a first groove recessed at the end away from the first flange; the second ring cover has a second groove recessed at the end away from the second flange; the first groove and the second groove communicate to form a cavity; the cavity is used for embedding the sealing ring.

[0013] Preferably, the sealing ring has an I-shaped cross-section; one end of the sealing ring is embedded in the cavity; and the other end of the sealing ring is attached to the inner wall of the first ring cover and the inner wall of the second ring cover.

[0014] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects: When splicing the ends of each pipe segment, this utility model first covers the connecting ends with ring caps and embeds the ends of the pipe segments into the corresponding limiting grooves. Then, the connection between the ring caps is achieved through the connecting components, thereby indirectly achieving the connection between the pipe segments. Compared with the existing technology that uses a pair of arc-shaped plate clamps for holding, this embodiment can prevent the layers of the pipe segments from separating from the connection point, thereby extending the service life.

Detailed Implementation

[0017] The specific implementation method is described below with reference to the accompanying drawings.

[0018] Example 1 Please see Figures 1 to 3 The present invention provides the following technical solution: a steel wire mesh skeleton pipe assembly structure, which is suitable for splicing or connecting various pipe sections.

[0019] Specifically, such as Figures 1 to 3 As shown, a steel wire mesh skeleton tube assembly structure includes a first ring cover 1 and a second ring cover 2; a first limiting groove 11 is provided at the end of the first ring cover 1 away from the second ring cover 2; a second limiting groove 21 is provided at the end of the second ring cover 2 away from the first ring cover 1; the first ring cover 1 is connected to the second ring cover 2 through a connecting component 3.

[0020] In this embodiment, when splicing the ends of the first pipe segment 8 and the second pipe segment 9, the first ring cover 1 is first applied to the end of the first pipe segment 8, and the end of the first pipe segment 8 is embedded in the first limiting groove 11. Similarly, the second ring cover 2 is applied to the end of the second pipe segment 9, and the end of the second pipe segment 9 is embedded in the second limiting groove 21. Thus, the ends of the two pipe segments to be connected are protected and reinforced. Furthermore, the first ring cover 1 and the second ring cover 2 are connected by the connecting component 3, thereby realizing the connection between the first pipe segment 8 and the second pipe segment 9. Compared with the prior art which uses a pair of arc-shaped plate clamps for clamping, this embodiment can avoid the separation of the layers of the pipe segments from the connection point.

[0021] Specifically, such as Figure 2 and Figure 3 As shown, the first ring cover 1 extends away from the second ring cover 2 and is provided with a first elastic ring piece 4 and a second elastic ring piece 5; the first elastic ring piece 4 and the second elastic ring piece 5 are provided at the groove end of the first limiting groove 11 and form a first annular groove communicating with the first limiting groove 11.

[0022] In this embodiment, the first elastic ring 4 and the second elastic ring 5 are both concentric rings, and their materials can be existing corrosion-resistant elastic steel sheets or elastic plastic sheets. The first annular groove formed by the first elastic ring 4 and the second elastic ring 5 not only has a certain radial groove width, but also a certain axial groove depth, thereby fully ensuring the limiting and reinforcement of the first pipe section 8, and effectively avoiding the influence of axial stress caused by internal pressure and temperature changes or external loads during the connection and use with the second pipe section 9.

[0023] In this embodiment, the radial width of the first annular groove is smaller than the radial width of the first limiting groove 11; a first buffer washer 6 is provided in the first limiting groove 11. The first buffer washer 6 has the characteristic of compressive elastic deformation, which can further effectively absorb and buffer most of the axial stress. Specifically, the material of the first buffer washer 6 can be commonly used EPDM rubber, neoprene rubber, etc.; furthermore, since the radial width of the first annular groove is smaller than the radial width of the first limiting groove 11, it can play a positioning role for the first buffer washer 6.

[0024] In this embodiment, in order to further enhance the stability of the connection between the first ring cover 1, the second ring cover 2 and the pipe segment, multiple openings for the insertion of positioning pins can be further opened on the side wall of the first ring cover 1, that is, the groove side wall of the first limiting groove 11. The stability between the first ring cover 1 and the first pipe segment 1 can be further strengthened by multiple positioning pins. Similarly, the second ring cover 2 and the second pipe segment 9 are also reinforced by multiple positioning pins.

[0025] Specifically, such as Figure 3 As shown, the second ring cover 2 extends away from the first ring cover 1 and is provided with a third elastic ring piece and a fourth elastic ring piece; the third elastic ring piece and the fourth elastic ring piece are provided at the groove end of the first limiting groove 11 and form a second annular groove communicating with the second limiting groove 21; the radial groove width of the second annular groove is smaller than the radial groove width of the second limiting groove 21; a second buffer washer is provided in the second limiting groove 21.

[0026] In this embodiment, the second ring cover 2 and its connection relationship with each structure are the same as the first ring cover 1. It reinforces the second pipe section 9 with the same structure and principle and can be connected to the first ring cover 1 through the connecting component 3.

[0027] In this embodiment, the cross-section of the second buffer washer and the cross-section of the second buffer washer are both U-shaped.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the connecting assembly 3 includes a first flange 31 and a second flange 32 screwed to the first flange 31; the first flange 31 is located on the outer side wall of the first ring cover 1; the second flange 32 is located on the outer side wall of the second ring cover 2.

[0029] In this embodiment, the flange bolt connection provides an effective and uniform axial locking force. This force is used to tighten the first ring cover 1 and the second ring cover, improving the sealing performance at the connection.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the first ring cover 1 has a first groove recessed at the end away from the first flange 31; the second ring cover 2 has a second groove recessed at the end away from the second flange 32; the first groove and the second groove communicate to form a cavity; the cavity is used for the sealing ring 7 to be embedded. The sealing ring 7 has an I-shaped cross-section; one end of the sealing ring 7 is embedded in the cavity; the other end of the sealing ring 7 is attached to the inner wall of the first ring cover 1 and the inner wall of the second ring cover 2.

[0031] In this embodiment, when the first flange 31 and the second flange 32 are tightened, the first ring cover 1 and the second ring cover are axially pulled closer, squeezing the middle I-shaped sealing ring 7. When it is under axial pressure, it will simultaneously generate radial expansion. The upper and lower horizontal ends of the "I" shape are tightly attached to the upper and lower walls of the cavity, forming the first static seal to prevent leakage at the interface between the two ring covers. After radial expansion, the middle vertical edge of the "I" shape is tightly attached to the inner side wall of the first and second ring covers, forming the second dynamic seal. It tightly holds the outer wall of the pipe, preventing the transported medium from seeping out along the pipe wall. Finally, it forms a double-lip, double-acting sealing structure, which effectively improves the stability of the seal, completely isolates external moisture and oxygen, protects the internal wire mesh from corrosion, and extends its service life.
