Embodiment 1

[0016] The solder ring of the present invention comprises two solder ring main bodies 1, each solder ring main body 1 is circular, the two solder ring main bodies 1 are coaxially arranged in parallel, and the two solder ring main bodies 1 are connected by a plurality of connecting columns 2. A plurality of connecting posts 2 are vertically connected between two solder ring main bodies 1, and the number of connecting posts 2 may be 4-6. The connecting column 2 is vertically connected between two adjacent solder ring main bodies 1, and the structure is stable.

Embodiment 2

[0018] The solder ring of the present invention comprises two solder ring main bodies 1, each solder ring main body 1 is circular, the two solder ring main bodies 1 are coaxially arranged in parallel, and the two solder ring main bodies 1 are connected by a plurality of connecting columns 2. A plurality of connecting posts 2 are obliquely and rotatably connected between two solder ring main bodies 1, and the number of connecting posts 2 may be 3-5. The connection post 2 is connected between the two solder ring main bodies 1 with an oblique rotation, so that the melting connection of the solder is more uniform.

Embodiment 3

[0020] The solder ring of the present invention comprises two solder ring main bodies 1, each solder ring main body 1 is circular, the two solder ring main bodies 1 are coaxially arranged in parallel, and a helical ring is connected between the two solder ring main bodies 1. Connecting column 2. A helical connecting column is connected between the two solder ring bodies, and the melting and welding of the solder is more uniform, and has certain toughness and is not easy to deform.

[0021] The solder ring of the present invention uses a plurality of solder ring bodies arranged in parallel on the same axis, and a connecting column is arranged between the plurality of solder ring bodies to form the entire solder ring. The structure of the entire solder ring is stable. The area is large, the solder is large, and the guiding performance is good, so it is not easy to cause missing soldering or uneven soldering.

Abstract

The invention discloses a solder ring which comprises at least two solder ring bodies. Each solder ring body is in a shape of circular ring. Several solder ring bodies are arranged coaxially and in parallel. Every two adjacent solder ring bodies are connected through one or more connecting poles. According to the solder ring of the invention, the whole solder ring is formed by utilizing several solder ring bodies arranged coaxially and in parallel and arranging the connecting poles among several solder ring bodies; the whole solder ring is steady in structure, has bigger contact area and more solder than the solder ring with the single ring and has good guiding performance; the solder skips or nonuniform welding is not easy to cause.

Description

technical field [0001] The invention relates to the technical field of copper pipe welding, in particular to a solder ring used for welding fillers. Background technique [0002] When the copper tubes in the heat exchanger are closed, the opening ends of the large bent tubes are generally connected by a small bent tube, and then fixed by welding. Welding needs to add welding filler, generally a welding ring is put on the small elbow to act as welding filler. The existing welding ring is a ring-shaped copper material. The material is small and the contact area is small, which cannot meet the welding requirements. It is easy to cause missing welding or uneven welding, which affects the quality of the product. Subsequent repair welding is required, which increases the labor cost. , affecting production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing welding ring is a ring-shaped copper mat...
