Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipeline connectors, and specifically relates to an internal thread quick joint. 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 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 locks it to quickly achieve the purpose of leak stoppage. 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. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an internal thread quick joint with relatively low cost and short production cycle.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] An internal thread quick joint, comprising a nut, an internal thread quick joint main body, a gasket and a sealing member, characterized in that: the internal thread quick joint main body contains a nut connection sealing member, an internal thread quick joint connecting pipe and an internal thread connecting member, one end of the internal thread quick joint connecting pipe is welded with the nut connection sealing member, and the other end of the internal thread quick joint connecting pipe is welded with the internal thread connecting member.
[0006] Further, the welding method of the internal thread quick joint connecting pipe and the nut connection sealing member is specifically laser welding, and the welding method of the internal thread quick joint connecting pipe and the internal thread connecting member is specifically laser welding.
[0007] Further, the materials of the nut connection sealing member, the internal thread quick joint connecting pipe and the internal thread connecting member are specifically stainless steel.
[0008] The beneficial effects of the utility model are:
[0009] In the present utility model, the nut, the sealing member, the internal-thread quick-connect pipe, and the internal-thread connecting member 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, without opening 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 the description of the embodiments or the prior art:
[0011] Figure 1 is a three-dimensional structure schematic diagram of the present utility model;
[0012] Figure 2 is a three-dimensional exploded structure schematic diagram of the present utility model;
[0013] Figure 3 is a three-dimensional structure schematic diagram of the internal-thread quick-connect main body of the present utility model;
[0014] Figure 4 is a three-dimensional exploded structure schematic diagram of the internal-thread quick-connect main body of the present utility model;
[0015] Figure 5 is a sectional view of the internal-thread quick-connect main body of the present utility model.
[0016] The reference numerals in the drawings are: 1 - nut, 2 - internal-thread quick-connect main body, 2a - nut connection sealing member, 2b - internal-thread quick-connect pipe, 2c - internal-thread connecting member, 3 - gasket, 4 - sealing member. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following will illustrate the detailed embodiments of the present utility model with reference to the drawings.
[0018] Referring to the attached Figure 1 — Figure 2 as shown:
[0019] An internal-thread quick-connect includes a nut 1, an internal-thread quick-connect main body 2, a gasket 3, and a sealing member 4. The nut 2 is threadedly connected to one end of the internal-thread quick-connect main body 2, and a gasket 3 and a sealing member 4 are installed between the nut 2 and the internal-thread quick-connect main body 2.
[0020] Referring to the attached Figure 3 — Figure 5 as shown:
[0021] The female quick-connect body 2 includes a nut connection seal 2a, a female quick-connect connecting pipe 2b, and a female connecting member 2c. One end of the female quick-connect connecting pipe 2b is welded with the nut connection seal 2a, and the other end of the female quick-connect connecting pipe 2b is welded with the female connecting member 2c.
[0022] In the present utility model, the materials of the nut connection seal 2a, the female quick-connect connecting pipe 2b, and the female connecting member 2c are specifically stainless steel. 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 oneself through mold opening. Moreover, there is no need to open a mold separately, so the cost is even cheaper, with obvious economic benefits.
[0023] 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 using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
