Description

Technical Field

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

[0002] A three-way quick connector is a connector 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 joint 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 leak stoppage. At this time, the pipeline quick connector 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. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a three-way 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 three-way quick connector includes a nut, a three-way quick connector body, a gasket and a seal. The three-way quick connector body includes a three-way body and a connecting pipe. The two ends of the three-way body are respectively welded with the connecting pipe. The connecting pipe includes a straight pipe and a threaded part. The straight pipe and the threaded part are connected together by welding.

[0006] Further, the welding method between the three-way body and the connecting pipe is specifically laser welding, and the welding method between the straight pipe and the threaded part is specifically laser welding.

[0007] Further, the materials of the three-way body, the straight pipe and the threaded part are specifically stainless steel.

[0008] The beneficial effects of the utility model are:

[0009] In the utility model, the three-way body and the connecting pipe are combined together by welding. 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 for combined welding and processing. The existing pipe fitting materials on the market are usually cheaper than the castings made by oneself by opening molds. In addition, there is no need to open a mold separately, so the cost is cheaper, and it has obvious economic benefits. Description of the Drawings

[0010] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art:

[0017] The following will describe the detailed implementation manners of the present invention with reference to the drawings.

[0018] Refer to the attached Figure 1 — Figure 2 as shown:

[0019] A tee quick-connect includes a nut 1, a tee quick-connect main body 2, a gasket 3 and a seal 4. The nut 2 is connected to both ends of the tee quick-connect main body 2 by means of threaded connection, and a gasket 3 and a seal 4 are installed between the nut 2 and the tee quick-connect main body 2.

[0020] Refer to the attached Figure 3 as shown:

[0021] The tee quick-connect main body 2 includes a tee main body 2a and a connecting pipe 2b. The connecting pipes 2b are respectively welded to both ends of the tee main body 2a, and the welding method is preferably laser welding.

[0022] Refer to the attached Figure 4 - Figure 5 as shown:

[0023] The connecting pipe 2b includes a straight pipe 2b1 and a threaded part 2b2. The straight pipe 2b1 and the threaded part 2b2 are connected together by welding, and the welding method is preferably laser welding.

[0024] In the present utility model, the materials of the tee main body 2a, the connecting pipe 2b and the nut connection seal 2c are specifically stainless steel. The tee main body 2a and the connecting pipe 2b are combined together by welding. Compared with the traditional casting method, the sample-making cycle of this structure and process is shorter because the mold-opening cycle is omitted. In addition, the welded pipe fittings can directly purchase the existing pipe fitting materials on the market for combined welding processing. The existing pipe fitting materials on the market are usually cheaper than the castings made by oneself through mold opening. Moreover, there is no need to open a mold separately, so the cost is cheaper and there is obvious economic benefit.

[0025] The above is only the specific implementation manner 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 by using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
