Description

Technical Field

[0001] The utility model relates to the technical field of metal gaskets, and specifically relates to a square metal gasket. Background Art

[0002] In municipal construction, pipelines are laid on the ground. Valves are provided between two adjacent pipelines, and the valves and pipelines are connected by flanges. In order to ensure the sealing performance of the flange connection, a metal gasket needs to be installed between the two flanges. The existing metal gaskets have various shapes, such as square metal gaskets, circular metal gaskets and other shapes.

[0003] The outer surface of the square metal gasket is in a flat state. During the use of the flange, its inner wall will be damaged due to wear by foreign objects or impact by external forces, resulting in an uneven contact surface between the flange and the square metal gasket. When the flange and the square metal gasket are assembled later, there will be a gap between the square metal gasket and the flange. At the same time, for the worn square metal gasket, there will also be a gap when it contacts the flange. When the medium in the pipeline passes through the flange, leakage will occur, affecting the safe transportation of the medium by the pipeline. In view of the deficiencies of the existing technology, we propose a square metal gasket to solve the above problems. Content of the Utility Model

[0027] The embodiments of the present utility model disclose a square metal gasket.

[0028] As shown in the attached Figures 1-4 It includes a metal gasket body 1. A support ring 11 is provided on the inner wall of the metal gasket body 1. A filling ring 12 is provided between the metal gasket body 1 and the support ring 11. Components such as the metal gasket body 1, the support ring 11, and the filling ring 12 form a square metal gasket. The outer shape of the metal gasket body 1 is square, a circular hole is opened inside the metal gasket body 1, the outer shape of the support ring 11 is circular, and the filling ring 12 is filled between the metal gasket body 1 and the support ring 11 by winding to form a sealing structure. And the support ring 11 is made of metal material, and the filling ring 12 can use graphite or polytetrafluoroethylene material according to different use environments. Installation holes 2 are provided at the four corners of the connecting metal sheet 31 and the metal gasket body 1. When the pipe body is connected to the valve cover, a flange will be used as an auxiliary. Before the two flanges are connected, a square metal gasket will be installed between the two flanges. Other shaped metal gaskets can also be installed between the two flanges, specifically according to actual needs. When the square metal gasket is arranged between the two flanges, it can further seal the connection between the two flanges, and a set of screws 33 can be installed at the installation holes 2 of the square metal gasket, so that the square metal gasket is fixedly connected to the flange through a set of screws 33, increasing the connection stability between the square metal gasket and the flange.

[0029] An auxiliary mechanism 3 is provided on one side of the metal gasket body 1. When the installation surface of the square metal gasket is an uneven surface, there is a gap between the smooth surface of the square metal gasket and the uneven surface. At this time, through the provided auxiliary mechanism 3, the gap between them can be filled and sealed. The auxiliary mechanism 3 includes a connecting metal sheet 31, and the shape of the connecting metal sheet 31 is equal to that of the square metal gasket. The connecting metal sheet 31 is connected to one side of the metal gasket body 1. A rubber part 32 is arranged on the side of the connecting metal sheet 31 away from the metal gasket body 1. The rubber part 32 fills and seals the gap between the metal gasket body 1 and other equipment parts. That is, the rubber part 32 with elastic deformation function fills and seals the gap between the smooth surface and the uneven surface of the square metal gasket, increasing the connection tightness at the joint of the square metal gasket and the square metal gasket. Thread teeth 34 are provided inside the connecting metal sheet 31. A round hole is provided on the inner wall of the connecting metal sheet 31, and the thread teeth 34 are provided on the inner wall of the round hole. One end of the rubber part 32 is fixedly connected with a thread ring 35, and the outer wall of the thread ring 35 is threadedly connected with the outer wall of the thread teeth 34, enabling convenient disassembly and replacement between the connecting metal sheet 31 and the rubber part 32 when any one of the rubber part 32 or the connecting metal sheet 31 is damaged. The inner diameter of the support ring 11 is equal to the inner diameter of the thread ring 35.

[0030] A screw 33 is rotatably arranged on one side of the connecting metal sheet 31. The connecting metal sheet 31 and the metal gasket body 1 are disassembled and assembled through the screw 33. A through hole 331 for the threaded installation of the screw 33 is provided on one side of the connecting metal sheet 31, and a threaded groove 332 for the threaded insertion of one end of the screw 33 is provided on one side of the metal gasket body 1. After the connecting metal sheet 31 and the metal gasket body 1 are assembled through the screw 33, the end of the screw 33 away from the threaded groove 332 will be located inside the through hole 331, so that the screw 33 will not protrude on one side of the connecting metal sheet 31, ensuring the flatness of one side of the connecting metal sheet 31.
