Description

Technical Field

[0001] The utility model relates to the technical field of compressor sealing, in particular to a sealing pad for a gas compressor. Background Art

[0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. Its main principle is to increase the gas pressure by reducing the gas volume and increasing the interaction force between gas molecules. It is often used to provide gas power for pneumatic tools. It is also commonly used to pressurize oxygen, hydrogen, ammonia, natural gas, coke oven gas, inert gas and other media in the petrochemical, drilling, metallurgy and other industries.

[0003] Gas compressors use flanges to connect pipelines. A gasket needs to be installed between the two flanges to ensure the sealing of the connection. However, existing gaskets are usually circular ring structures with average sealing effects and are prone to air leakage, especially after long-term use. Utility Model Content

[0007] As a preferred solution of the present invention, the second sealing tube is provided with a chamfer at one end away from the sealing gasket body.

[0008] As a preferred solution of the present invention, recessed portions are further provided on both sides of the sealing gasket body.

[0009] As a preferred solution of the present invention, the sealing gasket body, the first sealing cylinder, the oblique convex ring and the second sealing cylinder are an integrally formed structure.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figures 1 to 3 The utility model provides a technical solution: a sealing gasket for a gas compressor, comprising a sealing gasket body 1, a first sealing cylinder 2 is provided in the center of both sides of the sealing gasket body 1, the first sealing cylinder 2 is inserted into the pipeline after passing through the mounting hole in the center of the flange, and the oblique convex ring 3 is in close contact with the inner wall of the pipeline, playing a first sealing role. When the two flanges are in close contact, the sealing gasket body 1 is squeezed, and the sealing gasket body 1 plays a second sealing role between the two flanges, and the second sealing cylinder 4 is inserted into the bolt hole on the flange. When the bolt and nut are tightened, the bolt and nut will squeeze the second sealing cylinder 4, so that the second sealing cylinder 4 can seal the bolt hole on the flange, playing a third sealing role. Compared with traditional sealing gaskets, the sealing effect is greatly improved, and a plurality of oblique convex rings 3 are equidistantly provided on the outer side of the first sealing cylinder 2 along the length direction, and a plurality of second sealing cylinders 4 are equidistantly distributed in an annular shape on both sides of the sealing gasket body 1.

[0017] The inner wall of the second sealing cylinder 4 is provided with an internal thread 6, which is used to cooperate with the bolts of the fixed flange, thereby increasing the sealing between the second sealing cylinder 4 and the bolts.

[0018] The end of the second sealing cylinder 4 away from the sealing gasket body 1 is provided with a chamfer 5 , and the chamfer 5 makes it easier for the second sealing cylinder 4 to be inserted into the bolt hole on the flange.

[0019] The two sides of the gasket body 1 are provided with recessed parts 7, which are used to cooperate with the flanges on the flange so that no movement occurs between the gasket body 1 and the flange.

[0020] Among them, the sealing gasket body 1, the first sealing tube 2, the oblique convex ring 3 and the second sealing tube 4 are an integrally formed structure. The integrally formed structure not only ensures that the various components are firmly connected without gaps, but also facilitates production and manufacturing. The sealing gasket body 1, the first sealing tube 2, the oblique convex ring 3 and the second sealing tube 4 are all made of rubber. Rubber has excellent elasticity, can achieve a good sealing effect, and has a long service life. After long-term use, it can still maintain good sealing performance.

[0021] Specifically, during installation, align the first sealing sleeve 2 with the mounting hole in the center of the flange and insert the second sealing sleeve 4 into the bolt hole on the flange. After the first sealing sleeve 2 passes through the mounting hole in the center of the flange, it will be inserted into the pipe. The oblique convex ring 3 will be in close contact with the inner wall of the pipe, playing the role of the first sealing. Then, the two flanges are pressed together, and the bolts are passed through the bolt holes on the flanges and the second sealing sleeve 4. The nuts are screwed onto the bolts, and the bolts and nuts are tightened to achieve fixation between the two flanges. The two flanges will squeeze the sealing gasket body 1, playing the role of the second sealing. At the same time, the bolts and nuts will squeeze the second sealing sleeve 4, playing the role of the third sealing, thereby achieving a good sealing effect.
