Stainless steel water heating joint and production process thereof

Abstract

The invention discloses a stainless steel water heating joint and a production process thereof. The joint comprises a hexagonal shaft sleeve, a first connecting sleeve and a second connecting sleeve,wherein the first connecting sleeve and the second connecting sleeve are inserted in the hexagonal shaft sleeve, a first welding ring is formed between an outer ring of the end face of the first connecting sleeve and the inner wall of the hexagonal shaft sleeve through circumferential welding, and a chamfer is formed in the end face of the second connecting sleeve; and a second welding ring is formed between the outer wall of the second connecting sleeve and the end face, away from the first connecting sleeve, of the hexagonal shaft sleeve through circumferential welding, the first connectingsleeve abuts against the end face of the second connecting sleeve, and a containing space is formed between the chamfer and the end face of the first connecting sleeve and used for containing the first welding ring. The joint has the following advantages and effects that the scheme utilizes a new mechanical structure, and has the effects of environmental protection, simple technological process, high processing efficiency, low production cost and light finished product weight.

Description

technical field [0001] The invention relates to the technical field of joints, in particular to a stainless steel plumbing joint and a production process thereof. Background technique [0002] The plumbing joint is a standard component that can be used to connect water pipes and water meters. It is mainly composed of one end of the main body with an R1 thread and the other end with a G1 thread. The G1 thread section is threaded with a G1 nut, and the R1 thread passes through the raw material tape and Water pipe connection, the G1 thread is connected to the water meter through the G1 nut, and the nut is used to abut and fix. The existing production process for manufacturing plumbing joints is mainly divided into two types: 1) Brass is used as the main production material of the joint, and then Then the joint is integrally formed by red punching process (hot forging). The disadvantage of this production process is that the cost is high and the process is relatively complicated...

[0002] The plumbing joint is a standard component that can be used to connect water pipes and water meters. It is mainly composed of one end of the main body with an R1 thread and the other end with a G1 thread. The G1 thread section is threaded with a G1 nut, and the R1 thread passes through the raw material tape and Water pipe connection, the G1 thread is connected to the water meter through the G1 nut, and the nut is used to abut and fix. The existing production process for manufacturing plumbing joints is mainly divided into two types: 1) Brass is used as the main production material of the joint, and then Then the joint is integrally formed by red punching process (hot forging). The disadvantage of this production process is that the cost is high and the process is relatively complicated; 2). Stainless steel is used as the main production material of the joint, and then the lost wax casting process is used for the joint. The joints are integrally formed. The disadvantage of this production process is that during the lost wax casting process, a large number of pollution sources will be generated, which will pollute the environment to a certain extent.

[0003] The plumbing joints in the prior art are all made of one-piece molding, which has the disadvantages of complicated processing, low production efficiency, heavy weight and high production cost
