Description

Technical Field

[0001] The utility model relates to the field of pipeline connectors, and specifically relates to a pipeline quick connector. Background Art

[0002] A pipeline quick joint is a joint that can achieve the connection or disconnection of pipelines without tools. During the use of pipelines, due to factors such as building or road construction, the pipeline may leak or be damaged, and emergency repairs are required. Usually, a pipeline repairer is used to repair the damaged part of the pipeline; the pipeline repair section uses its shell and the sealing ring inside the shell to wrap the damaged part of the pipeline, and then locks it to quickly achieve the purpose of plugging. At this time, the pipeline quick joint can be quickly installed for emergency repair without tools. Traditional metal pipeline connectors are generally obtained by separately casting metal blank parts and then processing and assembling them. However, some metal castings are relatively expensive, and molds need to be developed before casting, so the production cycle is relatively long. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a pipeline quick connector with relatively low cost and short production cycle.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions;

[0005] A pipeline quick connector includes a quick-connecting main body, a locking gland, a sealing member, and a gasket. It is characterized in that: the quick-connecting main body is provided with a connecting body welding main body and a connector connecting end, and the quick-connecting main body and the connector connecting end are fixedly connected by welding.

[0006] Further, the welding method between the quick-connecting main body and the connector connecting end is specifically laser welding.

[0007] Further, the materials of the connecting body welding main body and the connector connecting end are stainless steel or copper.

[0008] Further, the surface of the connecting body welding main body is subjected to wire drawing treatment.

[0009] The beneficial effects of the utility model are:

[0010] In the utility model, the quick-connecting main body before turning is fixedly connected by welding the two ends of the connecting body welding main body with the end face cylinder of the connector after the first processing. This structure and process have a shorter sample-making cycle compared with the traditional casting method, because the mold-opening cycle is omitted, and the welded pipe fittings can directly purchase the existing pipe fitting materials on the market, so the cost is cheaper.

Specific embodiments

[0025] The following describes the specific embodiments of the present utility model with reference to the accompanying drawings.

[0026] Refer to the attached Figure 1 — Figure 3 as shown:

[0027] A pipeline quick connector includes a quick - connect main body 1, a locking gland 2, a seal 3 and a gasket 4. The locking gland 2 is thread - connected to the left and right ends of the quick - connect main body 1, and a seal 3 and a gasket 4 are installed between the locking gland 2 and the quick - connect main body 1.

[0028] Refer to the attached Figure 4 — Figure 7 as shown:

[0029] The unprocessed cylindrical body b1 of the connector end face becomes the cylindrical body b2 of the connector end face after the first processing through machining, and a positioning groove b21 is provided at the right end of the cylindrical body b2 of the connector end face after the first processing.

[0030] Refer to the attached Figure 8 — Figure 12 as shown:

[0031] Both ends of the connecting body welding main body 1a are fixedly connected to the connector end face cylinder b2 after the first processing through welding to form the quick-connection main body A1 before turning. The position of the junction 1ab between the connecting body welding main body and the processed connector end face cylinder is at the junction when the connecting body welding main body 1a is connected to the connector end face cylinder b2 after the first processing. By welding at the junction 1ab between the connecting body welding main body and the processed connector end face cylinder, the connecting body welding main body 1a and the connector end face cylinder b2 after the first processing are fixedly connected. The welding method can be electric welding, laser welding or argon arc welding, and laser welding is preferred. The inner diameter of the inner cylinder 1a1 of the connecting body welding main body is 0.1 - 0.2 mm larger than the outer diameter of the positioning groove b21 to facilitate the precise insertion of the inner cylinder 1a1 of the connecting body welding main body into the positioning groove b21, thereby ensuring the welding accuracy of the connecting body welding main body 1a and the connector end face cylinder b2 after the first processing. The quick-connection main body A1 before turning becomes the quick-connection main body 1 after turning processing. Among them, the connector end face cylinder b2 after the first processing becomes the connector connection end 1b after further machining, that is, the connector connection end 1b is machined from the connector end face cylinder b2 after the first processing. The quick-connection main body 1 is provided with a connecting body welding main body 1a and a connector connection end 1b. The surface of the connecting body welding main body 1a is treated by wire drawing, and the appearance is delicate and beautiful.

[0032] In the present utility model, the materials of the connecting body welding main body 1a and the connector connection end 1b are stainless steel or copper. In the traditional manufacturing method, the method for obtaining a large quantity of the quick-connection main body A1 before turning is to first open a mold and then cast it, which is costly and time-consuming. The quick-connection main body A1 before turning is formed by fixedly connecting both ends of the connecting body welding main body 1a to the connector end face cylinder b2 after the first processing through welding. Compared with the traditional manufacturing method, the sample-making cycle of this structure and process is shorter because the mold-opening cycle is omitted, and the welded pipe fittings can directly purchase the existing pipe fitting materials on the market, so the cost is cheaper.

[0033] The above is only the specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
