Description

Technical Field

[0001] This utility model relates to the field of metal gasket technology, specifically a metal gasket for pipe connections. Background Technology

[0002] Metal gaskets are made from high-precision, high-hardness sheet metal materials and are commonly used in the connections of pipes, valves, and other components to ensure the tightness and safety of the system and prevent liquid or gas leaks. They are widely used in piping systems in petrochemical, oil, natural gas, power generation, and many other industrial sectors. Common materials for metal gaskets include copper, steel, aluminum, and stainless steel. These materials have excellent high-temperature and high-pressure resistance, allowing metal gaskets to maintain a stable seal even in extreme environments. Furthermore, metal gaskets have good corrosion resistance and wear resistance, enabling them to adapt to a variety of harsh working environments.

[0003] However, existing pipe connection metal gaskets are not convenient to align their through holes with the through holes on the flange during actual use. During installation, a lot of time is required to adjust the position of the through holes. To address this problem, a pipe connection metal gasket is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a metal gasket for pipe connections to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a metal gasket for pipe connections, comprising a gasket, positioning cylinders provided on both sides of the gasket, a plurality of through holes formed on the gasket, a fixing ring provided in the inner cavity of each through hole, an elastic component provided in the inner cavity of the through hole, a positioning tube provided at the other end of the elastic component, a limiting component provided in the inner cavity of the through hole, the limiting component being fixedly connected to the outer wall of the positioning tube, and the positioning tube being slidably inserted into the inner cavity of the through hole.

[0005] Preferably, the end of the positioning cylinder away from the gasket is tapered.

[0006] Preferably, the elastic component includes a spring, one end of which is fixedly connected to the outer wall of the fixing ring, and the other end of which is fixedly connected to the bottom end of the positioning tube.

[0007] Preferably, the limiting component includes a limiting groove and a limiting block. The limiting groove is formed on the inner wall of the through hole, and the limiting block is slidably embedded in the inner cavity of the limiting groove and fixedly connected to the outer wall of the positioning tube.

[0008] Preferably, the inner cavity of the limiting groove and the outer wall of the limiting block are adapted to each other and are both in the shape of a "T".

[0009] Preferably, the outer walls of the gasket are provided with adhesive backing on both sides.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. By setting the positioning tube, the gasket can be positioned relative to the flange, ensuring that the central axis of the gasket and the flange are aligned. Squeezing the gasket moves it towards the flange, causing the flange to squeeze the positioning tube. Under the limiting action of the limiting groove and the limiting block, the positioning tube contracts along a straight line into the inner cavity of the through hole and squeezes the spring, causing the spring to undergo corresponding elastic deformation and generate corresponding elastic force. At this point, rotating the gasket causes it to rotate around its central axis. When the through hole on the gasket coincides with the through hole on the flange, the spring force allows the positioning tube to quickly reset and insert into the inner cavity of the through hole on the flange. This achieves the purpose of positioning the flange and the through hole on the gasket, facilitating gasket installation. This solves the problem of existing pipe connection metal gaskets where it is difficult to align the through hole on the gasket with the through hole on the flange during actual use, requiring a significant amount of time for adjustment during installation.

[0017] 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.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a pipe connection metal gasket, including a gasket 1, with positioning cylinders 2 on both sides of the gasket 1. The gasket 1 has several through holes 4, and each through hole 4 has a fixing ring 5 inside its cavity. An elastic component is provided inside the through hole 4, and a positioning tube 7 is provided at the other end of the elastic component. A limiting component is provided inside the through hole 4, and the limiting component is fixedly connected to the outer wall of the positioning tube 7. The positioning tube 7 is slidably inserted into the cavity of the through hole 4. Through the positioning cylinders 2, the position of the gasket 1 relative to the flange can be positioned, ensuring that the gasket 1 and the flange's central axis are aligned. Squeezing the gasket 1 moves it towards the flange, causing the flange to squeeze the positioning tube 7, thus limiting the positioning tube 7 within the limiting component. The inner cavity of the gasket 1 is contracted along a straight line to the through hole 4, and the elastic component is squeezed, causing the elastic component to produce corresponding elastic deformation, thereby generating corresponding elastic force. At this time, the gasket 1 is rotated, causing the gasket 1 to rotate around its central axis. When the through hole 4 on the gasket 1 coincides with the through hole 4 on the flange, under the action of the elastic force of the elastic component, the positioning tube 7 can be quickly reset and inserted into the inner cavity of the through hole 4 on the flange, thereby achieving the purpose of positioning the flange and the through hole 4 on the gasket 1, which facilitates the installation of the gasket 1. This solves the problem that in the actual use of the existing pipe connection metal gasket 1, it is not convenient to align the through hole 4 on it with the through hole 4 on the flange, and a lot of time is required to adjust the position of the through hole 4 during installation.

[0019] In this embodiment, the end of the positioning cylinder 2 away from the gasket 1 is tapered, which makes it easy for the positioning cylinder 2 to be inserted into the inner cavity of the flange.

[0020] In this embodiment, the elastic component includes a spring 6. One end of the spring 6 is fixedly connected to the outer wall of the fixing ring 5, and the other end of the spring 6 is fixedly connected to the bottom end of the positioning tube 7. When the through hole 4 on the gasket 1 coincides with the through hole 4 on the flange, under the elastic force of the spring 6, the positioning tube 7 can be quickly reset and inserted into the inner cavity of the through hole 4 on the flange, thereby achieving the purpose of positioning the flange and the through hole 4 on the gasket 1.

[0021] In this embodiment, the limiting component includes a limiting groove 8 and a limiting block 9. The limiting groove 8 is opened on the inner wall of the through hole 4. The limiting block 9 is slidably embedded in the inner cavity of the limiting groove 8 and fixedly connected to the outer wall of the positioning tube 7. Under the combined action of the limiting block 9 and the limiting groove 8, one end of the positioning tube 7 can always be inserted into the inner cavity of the through hole 4.

[0022] In this embodiment, the inner cavity of the limiting groove 8 and the outer wall of the limiting block 9 are adapted to each other and are both in the shape of a "T". This ensures that one end of the limiting block 9 is always embedded in the inner cavity of the limiting groove 8, thereby improving the stability of the limiting component during use.

[0023] In this embodiment, adhesive 3 is provided on both sides of the outer wall of the gasket 1. After the flange and the through hole 4 on the gasket 1 are aligned, the gasket 1 is pushed to make the gasket 1 and the flange come into close contact. Under the action of the adhesive 3, the gasket is connected to the flange. When installing the connecting bolts, there is no need to hold the gasket 1 to prevent it from falling off.
