[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0023] Example: Figures 1 to 4 As shown, the utility model gas leakage isolation joint comprises a gas leakage isolation joint body 2, one end of the gas leakage isolation joint body 2 is connected to a gas bellows 1, and a gas leakage isolation three-point sealing ring gasket 3 is arranged between the gas leakage isolation joint body 2 and the gas bellows 1, the gas leakage isolation three-point sealing ring gasket 3 can enhance the anti-static isolation effect and prevent safety accidents caused by leakage, and a gas leakage isolation joint locking cap 4 is threadedly arranged on the outer surface of the gas leakage isolation joint body 2 close to the gas bellows 1, and a gas leakage isolation insulation locking clamp 5 is clamped on the end of the gas leakage isolation joint locking cap 4 away from the gas leakage isolation joint body 2, and the gas leakage isolation insulation locking clamp 5 is clamped on the outer surface of the gas bellows 1.
[0024] During the installation process, the gas leakage isolation insulating locking spring 5 is clamped on the surface of the gas bellows 1, so that quick installation can be achieved. The gas leakage isolation insulating locking spring 5 and the gas leakage isolation joint locking cap 4 on the surface of the gas leakage isolation joint body 2 can have a locking effect, thereby enhancing the tightness of the connection between the gas leakage isolation joint body 2 and the gas bellows 1.
[0025] The material of the gas leakage isolation three-point sealing ring gasket 3 is one of EPDM rubber or nitrile rubber. EPDM rubber has excellent heat resistance, anti-aging performance, electrical insulation performance, chemical stability, wear resistance and tear resistance, while nitrile rubber has excellent oil resistance, flame retardancy, antistatic performance, insulation, wear resistance, corrosion resistance and high temperature resistance. Therefore, using one of these two materials can achieve the anti-static insulation performance of the gas leakage isolation three-point sealing ring gasket 3.
[0026] The gas bellows 1 is made of stainless steel, which can enhance its corrosion resistance, improve safety during use, and extend its service life.
[0027] An external thread is provided on the outer surface of the gas leakage isolation joint body 2 close to the gas bellows 1, and an internal thread is provided on the inner wall of the gas leakage isolation joint locking cap 4. The gas leakage isolation joint locking cap 4 is threadedly connected to the gas leakage isolation joint body 2 through the internal thread, and the two are connected by threads for easy disassembly and assembly.
[0028] The gas leakage isolation joint locking cap 4 is located outside the gas leakage isolation three-point sealing ring gasket 3, thereby also protecting the gas leakage isolation three-point sealing ring gasket 3 and preventing it from being affected by the external environment and shortening its service life or affecting the use effect.
[0029] The gas leakage isolation insulating locking clip 5 is made of nylon, which is strong and durable, light and flexible, and easy to use.
[0030] One end of the gas leakage isolation insulating locking spring 5 close to the gas leakage isolation joint body 2 is arranged between the gas bellows 1 and the gas leakage isolation joint locking cap 4, and the end of the gas leakage isolation insulating locking spring 5 close to the side of the gas bellows 1 is clamped between the corrugated grooves of the gas bellows 1. Due to the threaded connection relationship between the gas leakage isolation joint locking cap 4 and the gas leakage isolation joint body 2, and the clamping relationship between the gas leakage isolation joint locking cap 4 and the gas leakage isolation insulating locking spring 5, the gas leakage isolation insulating locking spring 5 can be driven to move by the gas leakage isolation joint locking cap 4, and the gas bellows 1 can be clamped by the gas leakage isolation insulating locking spring 5.
[0031] During operation, by setting a gas leakage isolation three-point sealing ring gasket 3 between the gas bellows 1 and the gas leakage isolation joint body 2, the leakage isolation function can be enhanced, and the safety during use can be improved. There is no need to manually install the anti-static isolation joint for a second time, and the cost of installing the anti-static isolation joint is also saved. In the installation process, the gas leakage isolation insulation locking spring 5 is clamped on the surface of the gas bellows 1, so that quick installation can be achieved, and the surface of the gas leakage isolation joint body 2 and the gas leakage isolation insulation locking spring 5 is locked by the gas leakage isolation joint locking cap 4 to enhance the tightness of the connection.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
