Problems solved by technology

[0002] Some systems need to use pipe fittings to control the confluence or diversion of fluids, so as to control the fluid in the flow path, such as air conditioning systems. Generally, the pipe fittings and the pipes of the system are made of the same material, which is conducive to welding and connection. Relatively convenient, the general air-conditioning system uses copper pipes for connection, but the processing of the connection device of copper pipe fittings may require surface treatment such as pickling, which has a certain impact on environmental protection

Abstract

The invention discloses a pipe fitting connecting device and a manufacturing method. The pipe fitting connecting device comprises a main pipe made of a stainless steel material, a connecting pipe made of a copper material and at least one submerged pipe, one of the connecting pipe and the first matching part of the main pipe is provided with a concave-convex part at the matching welding part; at least part of the submerged pipe is located in the main pipe cavity, the submerged pipe and the main pipe are welded in a matched mode, and a concave-convex part is arranged at the matched welding position of one of the submerged pipe and the main pipe, so that assembling and subsequent welding of the main pipe, the connecting pipe and the submerged pipe are facilitated.

Description

【Technical field】 [0001] The invention relates to the field of fluid control, in particular to a pipe fitting connecting device and a manufacturing method. 【Background technique】 [0002] Some systems need to use pipe fittings to control the confluence or diversion of fluids, so as to control the fluid in the flow path, such as air conditioning systems. Generally, the pipe fittings and the pipes of the system are made of the same material, which is conducive to welding and connection. Relatively convenient, the general air-conditioning system uses copper pipes for connection, but the processing of copper pipe fittings connection devices may require surface treatment such as pickling, which has a certain impact on environmental protection. 【Content of invention】 [0003] In order to provide a new connection device for pipe fittings, the main body of which can be made of stainless steel and can be welded with the copper pipes of the system, etc., the present invention provid...
