Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, in particular to a skeleton rubber heating ventilation part used for pipeline sealing interfaces. Background Art

[0002] Pipe connectors refer to pipeline components that are used for connecting pipelines or installed at pipeline connection locations and play a certain role in the connection between pipelines. Common ones include pipe clamps, joints, valves, gaskets, etc., which are widely used.

[0003] The existing gasket structure for pipe connection has the following disadvantages when used: the gasket is made of paper, rubber sheet or copper sheet, and is placed between two planes to strengthen the seal. In order to prevent fluid leakage, a sealing element is set between static sealing surfaces. Rubber gaskets are often used as pipe connectors in pipes. The existing gasket structure for pipe connection is generally an ordinary circular structure, which is prone to deformation and other problems during long-term use. Therefore, we propose a skeleton rubber HVAC component for pipe sealing interfaces. Utility Model Content

[0004] The main purpose of the utility model is to provide a skeleton rubber HVAC component for pipeline sealing interfaces. By improving the gasket body, the gap between two adjacent coupling surfaces is controlled below the minimum gap through which the liquid to be sealed can pass, which plays a reinforcing role and enables the seal to maintain its shape and tension, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A skeleton rubber heating ventilation part for pipeline sealing interface includes a gasket body, wherein the inner circumference of the gasket body is integrally formed with a convex ring and slots are opened between adjacent convex rings, and the inner circumference of the gasket body is provided with serrated grooves at positions inside the slots.

[0007] Furthermore, flange docking holes are equidistantly opened inside the gasket body, and plug rings are inserted into the flange docking holes; when normally used in ordinary pipe docking, the plug rings are inserted into the flange docking holes. At this time, the gasket body is directly installed at the connection between the pipes to play a sealing role. When the gasket body needs to seal the pipe with the flange joint, the plug ring can be taken out from the flange docking hole to expose the flange docking hole. When installing, it is aligned with the internal mounting hole of the flange joint at the end of the pipe, which can facilitate the penetration of the fastener.

[0008] Furthermore, the gasket body is made of rubber material, the length of the convex ring is 2 mm, and the radial width of the convex ring is 2 mm; the rubber material has the characteristics of good elasticity, reliable sealing, resistance to high temperature and high pressure, and anti-aging.

[0009] Furthermore, end rings are integrally formed at both ends of the plug ring surface, and the end rings are both fitted to the surface of the gasket body; the end rings at both ends of the plug ring can be fitted to the surface of the gasket body after the plug ring is inserted into the flange docking hole, thereby improving the sealing of the connection.

[0010] Furthermore, the plug ring and the end ring are both made of rubber; the plug ring and the end ring made of rubber can be squeezed and deformed, and are convenient for installation and removal.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the interior of the gasket body is processed with a convex ring structure and slots are provided between the convex rings, and the inner wall of the slot is provided with a serrated groove. Compared with the existing ordinary circular ring-shaped gasket structure, after the gasket body is installed in place, the non-smooth surface of its inner circumference makes the bonding surface between the gasket and the pipe interface rough, thereby enhancing the area and bonding force between the two. At the same time, the internal slots and serrated groove structure control the gap between the two adjacent coupling surfaces to be below the minimum gap that the liquid to be sealed can pass through, thereby playing a reinforcing role and enabling the seal to maintain its shape and tension, not easily deformed, thereby improving the service life and sealing effect. When normally used in ordinary pipe docking, the plug ring is inserted into the flange docking hole. At this time, the gasket body is directly installed at the connection between the pipes to play a sealing role. When the gasket body needs to seal and dock a pipe with a flange joint, the plug ring can be removed from the flange docking hole to expose the flange docking hole. When installing, it is aligned with the internal mounting hole of the flange joint at the end of the pipe, which can facilitate the insertion of the fastener. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-3As shown, a skeleton rubber heating and cooling component for pipe sealing interfaces includes a gasket body 1, wherein a convex ring 2 is integrally formed on the inner circumference of the gasket body 1 and slots 3 are opened between adjacent convex rings 2, and a serrated groove 4 is opened on the inner circumference of the gasket body 1 at a position inside the slot 3.

[0018] Among them, flange docking holes 5 are equidistantly opened inside the gasket body 1, and plug rings 6 are inserted into the flange docking holes 5; when normally used in ordinary pipe docking, the plug rings 6 are inserted into the flange docking holes 5. At this time, the gasket body 1 is directly installed at the connection between the pipes to play a sealing role. When the gasket body 1 needs to seal the pipe with a flange joint, the plug ring 6 can be taken out from the flange docking hole 5 to expose the flange docking hole 5. When installing, it is aligned with the internal mounting hole of the flange joint at the end of the pipe to facilitate the penetration of the fastener.

[0019] Among them, the gasket body 1 is made of rubber material, the length of the convex ring 2 is 2mm, and the radial width of the convex ring 2 is 2mm; the rubber material has the characteristics of good elasticity, reliable sealing, high temperature and high pressure resistance, and aging resistance.

[0020] Among them, end rings 7 are integrally formed at both ends of the surface of the plug ring 6, and the end rings 7 are both attached to the surface of the gasket body 1. The plug ring 6 and the end rings 7 are both made of rubber; the end rings 7 at both ends of the plug ring 6 can be attached to the surface of the gasket body 1 after the plug ring 6 is inserted into the flange docking hole 5, thereby improving the sealing of the connection. The plug ring 6 and the end ring 7 made of rubber can be squeezed and deformed, which is convenient for installation and disassembly.

[0021] It should be noted that the present invention is a skeleton rubber heating ventilation part for pipe sealing interface. When in use, the interior of the gasket body 1 is processed into a convex ring 2 structure and a slot 3 is provided between the convex ring 2. The inner wall of the slot 3 is provided with a serrated groove 4. Compared with the existing ordinary circular gasket structure, after the gasket body 1 is installed in place, the non-smooth surface of its inner circumference makes the bonding surface between the gasket and the pipe interface rough, thereby enhancing the area and bonding force between the two. At the same time, the internal slot 3 and the serrated groove 4 structure control the gap between the two adjacent coupling surfaces to a level that the liquid to be sealed can pass through. The minimum gap between the two flanges is less than 5, which plays a reinforcing role and enables the seal to maintain its shape and tension, not easily deformed, and improves its service life and sealing effect. When normally used in ordinary pipe joints, the plug ring 6 is inserted into the flange joint hole 5. At this time, the gasket body 1 is directly installed at the connection between the pipes to play a sealing role. When the gasket body 1 needs to seal the pipe with the flange joint, the plug ring 6 can be taken out from the flange joint hole 5 to expose the flange joint hole 5. When installing, it is aligned with the internal mounting hole of the flange joint at the end of the pipe to facilitate the penetration of the fastener.
