Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 5, the present utility model provides a three-way assembly, which comprises a main pipe 10 and an extrusion pipe 20, wherein the extrusion pipe 20 is formed by extrusion of a part of the middle part of the main pipe 10, a first end of the extrusion pipe 20 is communicated with the main pipe 10, and a second end of the extrusion pipe 20 and two ends of the main pipe 10 are respectively used for connecting with other pipelines or devices.

In this scheme, extrusion pipe 20 in this tee bend subassembly is passed through extrusion process shaping by the part structure at the middle part of being responsible for 10, the second end of extrusion pipe 20, the both ends of being responsible for 10 have formed three intercommunication respectively and have been joined to three way construction has been formed, because be responsible for 10 and extrusion pipe 20 integrated into one piece, and the intercommunication joint that is responsible for 10 and form directly satisfies the length requirement, compare with current tee bend subassembly, can reduce the rethread pipe welding in order to satisfy the intercommunication joint length demand, consequently reduce the overburning that the welding tee bend caused among the prior art, weld stifled and leak risk, reliability and life are high.

Of course, the length of extruded tube 20 cannot be too long due to the extrusion process and product quality requirements. In some use environments, the length of the extruded tube 20 itself may meet the use requirements so that the tee assembly has no welds; in some circumstances, where the length of the extruded tube 20 itself is relatively short, it is desirable to connect a length of the extended length tube to the extruded tube 20 by welding, in which case the tee assembly also has only one weld. Therefore, the tee joint assembly provided by the method has no welding spot or only one welding spot in the whole structure, so that the problem caused by repeated welding is avoided or reduced, and the product quality is improved. And moreover, the tee joint assembly has the advantages of less material investment and larger cost advantage.

As shown in fig. 1, for the case where the length of the extruded tube 20 itself cannot meet the use requirement, the tee assembly further includes an extension tube 30, the extension tube 30 being welded to the second end of the extruded tube 20. Because of the process requirements, the extruded tube 20 has a diameter not greater than the diameter of the main tube 10, and the length, diameter and extension direction of the extension tube 30 are selected as desired to improve the application range.

For example, the diameter of the extension pipe 30 is equal to the diameter of the main pipe 10, or the diameter of the extension pipe 30 is larger than the diameter of the main pipe 10, or the diameter of the extension pipe 30 is smaller than the diameter of the main pipe 10. The extension tube 30 may be a straight tube or a curved tube.

Specifically, in fig. 2, for the case where the diameter of the extension pipe 30 is greater than or equal to the diameter of the main pipe 10, the second end of the extruded pipe 20 is of a flared structure, and one end of the extension pipe 30 is inserted into the flared structure and welded, so that reliable connection of the two is achieved, and the three-way assembly provided by the scheme has fewer welding points.

Or in the case where the diameter of the extension pipe 30 is larger than that of the main pipe 10, the second end of the extruded pipe 20 is inserted into one end of the extension pipe 30 and welded.

As shown in FIG. 3, the extruded tube 20 is a straight tube, and the included angle between the extruded tube 20 and the main tube 10 is a, and a is more than 0 degrees and less than or equal to 90 degrees. In this scheme, can be according to reducing and improving the angle of liquid velocity of flow adjustment extrusion pipe 20 to satisfy the air conditioner structure and to the requirement of control liquid velocity of flow.

In this embodiment, the length of the extruded tube 20 is less than 50mm. The length of the extruded tube 20 formed by the extrusion process should not be too long, and if the length is too long, the thickness of the extruded tube 20 will be relatively thin, so that the strength requirement is not satisfied. By adopting the existing mature extrusion process, the length of the extrusion pipe 20 can be in the range of less than 50mm, and the use requirement of the air conditioner is met.

Wherein the outer diameter of the main pipe 10 is 6mm to 19mm, and the wall thickness of the main pipe 10 is 0.5mm to 2.0mm. The technical scheme is suitable for pipelines with smaller diameters, particularly suitable for connecting pipelines of air conditioners, and has the advantages of saving materials, being low in cost and high in strength. The wall thickness of the main pipe 10 is limited to 0.5mm to 2.0mm, so that the wall thickness and the compression resistance of the extruded pipe 20 can be ensured to meet the use requirements of the air conditioner.

As shown in fig. 1, the main pipe 10 includes a first pipe 11 and a second pipe 12 connected to each other, the diameters of the first pipe 11 and the second pipe 12 are equal, a first end of the extruded pipe 20 is located at a joint between the first pipe 11 and the second pipe 12, and the extruded pipe 20, the first pipe 11, and the second pipe 12 are connected in pairs. In this scheme, before the main pipe 10 is as raw material pipe extrusion, select length can be longer, and extrusion pipe 20 back like this, the length of first pipe 11 and second pipe 12 satisfies the operation requirement, need not to take over again, has consequently reduced the solder joint, has avoided the back of many times high temperature welding, and the product takes place the risk of overburning, welding stifled and leakage easily.

After extrusion is completed, the first pipe 11 and the second pipe 12 are initially straight pipes, the pipe can be bent according to the use requirement, and the position and the angle of the bent pipe can be flexibly selected. In fig. 1, a portion of the first tube 11 remote from the extruded tube 20 is bent, and the bent first tube 11 includes a first straight tube 111 and a first bent tube 112 connected to each other; a portion of the second tube 12 remote from the extruded tube 20 is bent, and the bent second tube 12 includes a second straight tube 121 and a second bent tube 122 connected to each other; the first straight pipe 111 and the second straight pipe 121 are coaxial and are both communicated with the extruded pipe 20, and the first bent pipe 112 and the second bent pipe 122 are respectively used for being connected with other pipelines or devices. The bending direction and angle of the first bent pipe 112 and the second bent pipe 122 are selected according to the use requirement.

In this embodiment, the main pipe 10 is made of copper alloy, aluminum alloy or stainless steel, and the extruded pipe 20 can be manufactured by extrusion process.

In another embodiment, as shown in fig. 4, unlike the above embodiment, a portion of the extruded tube 20 away from the main tube 10 is bent, and the bent extruded tube 20 includes a first extruded section 21 and a second extruded section 22 connected to each other, the first extruded section 21 and the main tube 10 being in communication, and the second extruded section 22 being for connection with other pipes or devices. The extending direction of the second end of the extruded tube 20 can be changed by bending to meet the use requirements. This embodiment is particularly suitable for the case where the length and diameter of the extruded tube 20 itself satisfy the use requirements, so that there is no need to weld an extension tube, and there is no problem caused by welding. The three-way component has obvious advantages, no welding leakage hidden trouble, no welding blockage caused by welding and influence on the flow of the whole machine, and the three-way component has less investment of structural materials and larger cost advantage.

As shown in FIG. 5, the angle between the first pressing section 21 and the main pipe 10 is b,0 DEG < b.ltoreq.90°. That is, in this embodiment, the angle of the squeeze tube 20 can be adjusted according to the decrease and increase of the liquid flow rate, so as to meet the requirement of the air conditioning structure for controlling the liquid flow rate.

as shown in fig. 1 and 2, when the pipe diameter (main pipe 10) of the selected raw material is equal to or larger than the pipe diameter required by the extrusion part (extrusion pipe 20), other pipes are welded by adopting flaring for the extrusion part. As shown in fig. 3, if the air conditioning structure has a high requirement for controlling the flow rate of the liquid, the angle of the pressing portion may be adjusted according to the decrease and increase of the flow rate of the liquid.
