Problems solved by technology

[0002] At present, the quick-connect pipes used for water heaters and plumbing fittings generally consist of two parts, the installation part and the pipe part. The sealing groove; its production process is to process the pipeline part and the installation part separately, and then weld them to form a finished product. The steps are cumbersome, which increases the production cost; second, the finished products formed by welding are prone to defective products. After a long period of use, the welding points are easy to be damaged and the service life is short

Embodiment Construction

[0023] The present invention will be further described below with specific embodiment, see Figure 1-7 :

[0024] The production process of the quick-connect pipe comprises the following steps:

[0025] 1) One-time flaring: flaring one end of the round pipe, so that one end of the round pipe is a large-diameter round pipe 2, and the other end is a small-diameter round pipe 1;

[0026] 2) Shaping: the round tube made in step 1) is shaped, and two sections of round tubes with different diameters are adjusted in place according to the length requirements;

[0027] 3) Swivel groove: carry out swirl groove in the middle of the large-diameter circular tube 2a made in step 2), and divide the large-diameter circular tube 2a into three parts, from right to left, the large-diameter circular tube 2b, the sealing groove Groove 4 and large convex ring 3;

[0028] 4) Closing: closing the large-diameter round pipe 2b of the round pipe in step 3) to form a closing section 2c;

[0029] 5) ...

Description

Technical field: [0001] The invention belongs to the technical field of connecting pipes, in particular to a production process of quick connecting pipes. Background technique: [0002] At present, the quick-connect pipes used for water heaters and plumbing fittings generally consist of two parts, the installation part and the pipe part. The sealing groove; its production process is to process the pipeline part and the installation part separately, and then weld them to form a finished product. The steps are cumbersome, which increases the production cost; the second is that the finished product formed by welding is prone to defective products. After the product is used for a long time, the welding point is easy to be damaged and the service life is short. Invention content: [0003] The object of the present invention is to provide a production process of quick-connect pipes with low cost, convenient use, reliability and long service life. [0004] The present invention...
