Description

Technical Field

[0001] The utility model relates to the field of pipe connectors, in particular to a quick elbow joint. Background Art

[0002] A quick elbow joint is a joint that can connect or disconnect pipelines without tools. During the use of pipelines, due to factors such as building or road construction, pipelines may leak or be damaged, and emergency repairs are required. Usually, a pipeline emergency repair device is used to repair the damaged part of the pipeline; the pipeline emergency repair section uses its shell and the sealing ring inside the shell to wrap the damaged part of the pipeline and then lock it to quickly achieve the purpose of plugging leaks. 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 machining 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 an external thread quick joint with relatively low cost and short production cycle.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions;

[0005] A quick elbow joint includes a nut, a quick elbow joint body, a gasket, and a seal. It is characterized in that: the quick elbow joint body includes an elbow body, a connecting pipe, and a nut connecting seal. The two ends of the elbow body are respectively welded with the connecting pipe, and one end of the connecting pipe is welded with the nut connecting seal.

[0006] Further, the welding method between the elbow body and the connecting pipe is specifically laser welding, and the welding method between the connecting pipe and the nut connecting seal is specifically laser welding.

[0007] Further, the materials of the elbow body, the nut connecting seal, and the connecting pipe are specifically stainless steel.

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

[0009] In the present utility model, the materials of the elbow main body, the connecting pipe, and the nut connecting seal are specifically stainless steel, and they 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 self-opening molds. Moreover, since there is no need to open molds separately, the cost is even cheaper, having obvious economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for description in the embodiments or the prior art:

[0015] The following will describe the specific embodiments of the present utility model with reference to the drawings.

[0016] Refer to the attached Figure 1 — Figure 2 as shown:

[0017] An elbow quick-connect includes a nut 1, an elbow quick-connect main body 2, a gasket 3, and a seal 4. The nut 2 is connected to one end of the elbow 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 elbow quick-connect main body 2.

[0018] Refer to the attached Figure 3 as shown:

[0019] The elbow quick-connect main body 2 includes an elbow main body 2a, a connecting pipe 2b, and a nut connecting seal 2c. Connecting pipes 2b are respectively welded to both ports of the elbow main body 2a, and the welding method is preferably laser welding. A nut connecting seal 2c is welded to one end of the connecting pipe 2b, and the welding method is preferably laser welding.

[0020] In the present utility model, the materials of the elbow main body 2a, the connecting pipe 2b, and the nut connection seal 2c are specifically stainless steel, and they are combined together by welding. This structure and process have a shorter sample-making cycle compared to the traditional casting method because the mold-opening cycle is omitted. Additionally, the welded pipe fittings can directly use 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 one's own mold. Moreover, without the need to open a separate mold, the cost is even cheaper, showing obvious economic benefits.

[0021] 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 of the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
