Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline technology, and in particular to a rubber flange gasket for chemical pipelines. Background Technology

[0002] Chemical pipelines are pipeline systems used to transport chemical raw materials, intermediate products, final products, and by-products. These pipelines play a vital role in the chemical production process, ensuring the safe and efficient transmission of various fluid substances.

[0003] Rubber flange gaskets for chemical pipelines are sealing components used at flange connections in chemical pipelines, and they are typically made of high-performance rubber materials.

[0004] The existing rubber flange gasket for chemical pipelines has the following shortcomings:

[0005] Flange gaskets, as sealing elements in pipe flange connections, are used to ensure a tight seal between two flanges. However, in the existing technology, the installation process of flange gaskets is relatively complicated and prone to falling off, resulting in an unstable and inconvenient connection. This not only wastes a lot of installation time but also significantly reduces connection efficiency. Utility Model Content

[0006] This utility model anti-slip mat utilizes the elastic force of a compression spring to apply force to the flange. With the cooperation of the arc-shaped block, it can initially fix the gasket body and prevent the gasket body from falling off during installation, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a rubber flange gasket for chemical pipelines, comprising a connecting mechanism, wherein an auxiliary fixing mechanism is slidably connected inside the connecting mechanism; the connecting mechanism comprises a gasket body, wherein fixing blocks are fixedly connected to both sides of the outer wall of the gasket body, and arc-shaped blocks are fixedly connected to opposite sides of the two fixing blocks; a first sliding rod is fixedly connected to the outer wall of each fixing block; a first connecting plate is fixedly connected to the extended end of the first sliding rod; a second sliding rod is fixedly connected to the outer wall of each first connecting plate; a compression spring is sleeved on the outer wall of the second sliding rod; an anti-slip pad is fixedly connected to the shaft end of the second sliding rod; a guide rod is fixedly connected to the outer wall of each arc-shaped block; and a second connecting plate is fixedly connected to the outer wall of each first connecting plate.

[0008] Preferably, the outer wall of the arc-shaped block is fixedly connected to the outer wall of the gasket body, and the inner wall of the second connecting plate is slidably connected to the outer wall of the guide rod, so as to avoid interference with the movement of the second connecting plate. Furthermore, the guide rod can improve the stability of the second connecting plate, the second sliding rod, the compression spring, and the anti-slip pad during horizontal movement.

[0009] Preferably, one end of the compression spring is fixedly connected to the outer wall of the anti-slip pad, and the other end of the compression spring is fixedly connected to the outer wall of the first connecting plate, so that the compression spring will not detach under any state.

[0010] Preferably, a sealing ring is fixedly connected to the inner wall of the gasket body. In actual use, the sealing ring will be inside the pipe body, thereby improving the sealing performance of the connection and preventing leakage of the medium inside the pipe.

[0011] Preferably, the auxiliary fixing mechanism includes a pipe body, the outer wall of which is provided with a flange, and the outer wall of the pipe body is slidably connected to the outer wall of the sealing ring and the arc block. The flange facilitates the user to connect the two pipe sections together.

[0012] Preferably, each of the pipe bodies has a fixedly connected positioning block on its outer wall, and a bolt is threaded through the outer wall of the positioning block. The positioning block and the bolt ensure that the gasket body can be stably positioned between the two pipe bodies. By using the tightening force, the flange can be made to fully contact the gasket body, thereby improving the sealing performance.

[0013] Preferably, each bolt has a handle fixedly connected to its outer wall, which allows the user to easily tighten the bolt.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when the positioning mechanism is placed between the two flanges, the second connecting plate is pulled, causing the first sliding rod to be stressed, and driving the first connecting plate, the second sliding rod, the compression spring and the anti-slip pad to move, so as to avoid interference during placement. After placement, the anti-slip pad can exert force on the flange by utilizing the elastic force of the compression spring. With the cooperation of the arc block, it can play a preliminary role in fixing the gasket body, and at the same time, it can prevent the gasket body from falling off during installation, making the connection more stable and convenient for installation.

[0016] 2. In this utility model, the threaded fixing mechanism can achieve a secondary fixing effect on the gasket body, and the twisting force can make the gasket body fully contact the outer wall of the flange, thereby improving the sealing performance. The sealing ring will be located inside the body, thereby improving the sealing performance at the connection. Attached Figure Description

[0024] Please see Figures 1-4 This utility model provides a technical solution: a rubber flange gasket for chemical pipelines, including a connecting mechanism 1, with an auxiliary fixing mechanism 2 slidably connected inside the connecting mechanism 1; the connecting mechanism 1 includes a gasket body 101, with fixing blocks 107 fixedly connected to both sides of the outer wall of the gasket body 101, and arc-shaped blocks 110 fixedly connected to opposite sides of the two fixing blocks 107; a first sliding rod 102 is fixedly connected to the outer wall of each fixing block 107, a first connecting plate 103 is fixedly connected to the extended end of the first sliding rod 102, a second sliding rod 111 is fixedly connected to the outer wall of each first connecting plate 103, a compression spring 109 is sleeved on the outer wall of the second sliding rod 111, an anti-slip pad 108 is fixedly connected to the shaft end of the second sliding rod 111, a guide rod 104 is fixedly connected to the outer wall of each arc-shaped block 110, and a second connecting plate 106 is fixedly connected to the outer wall of each first connecting plate 103.

[0025] like Figure 3 and Figure 4As shown, the outer wall of the arc-shaped block 110 is fixedly connected to the outer wall of the pad body 101, and the inner wall of the second connecting plate 106 is slidably connected to the outer wall of the guide rod 104, so as to avoid interference with the movement of the second connecting plate 106. Furthermore, the guide rod 104 can improve the stability of the second connecting plate 106, the second sliding rod 111, the compression spring 109, and the anti-slip pad 108 during horizontal movement.

[0026] like Figure 3 As shown, one end of the compression spring 109 is fixedly connected to the outer wall of the anti-slip pad 108, and the other end of the compression spring 109 is fixedly connected to the outer wall of the first connecting plate 103, so that the compression spring 109 will not detach in any state.

[0027] like Figure 3 As shown, a sealing ring 105 is fixedly connected to the inner wall of the gasket body 101. In actual use, the sealing ring 105 will be inside the pipe body 201, which can improve the sealing performance of the connection and prevent the leakage of the medium in the pipe.

[0028] like Figure 2 As shown, the auxiliary fixing mechanism 2 includes a pipe body 201. The outer wall of the pipe body 201 is provided with a flange 202. The outer wall of the pipe body 201 is slidably connected to the outer wall of the sealing ring 105 and the arc block 110.
