Abstract

The utility model discloses a distributor for connecting air-conditioner pipelines. The distributor for connecting the air-conditioner pipelines comprises a distributor body. Two through holes matched with the pipe diameter of a copper pipe are formed at one end of the distributor body in a flaring mode. A single hole matched with the copper pipe is formed at the other end of the distributor body in a mouth shrinking mode. Prismatic table positioning circular grooves are formed in welding points of two end portions of the distributor body and the copper pipe. The distributor for connecting the air-conditioner pipelines has the advantages that due to the fact that the prismatic table positioning circular grooves are formed at positioning positions on the periphery of the distributor body in an encircling mode, the positioning contact area between the distributor and the matched copper pipe is enlarged. When the copper pipe is welded and heated, the copper pipe can not pass through the prismatic table positioning circular grooves easily, and therefore the damage to the thickness of a copper pipe wall by a point location in the process of processing and positioning is effectively eliminated in the prior art. Location dimension is enabled to be accurate, and welding quality is stable. Hidden danger of refrigerant leakage is avoided, and product quality is improved.

Description

Allotter for air-conditioner pipeline connecting

Technical field

The utility model relates to a kind of distributor; Particularly relate to a kind of allotter for air-conditioner pipeline connecting.

Background technology

Allotter for air-conditioner pipeline connecting is parts of the inner copper pipe bond pads of air-conditioning, Fig. 1 to Fig. 3 is the schematic diagram of existing copper pipe distributor, as shown in Figure 1 to Figure 3, main distributor 1 one two of end enlarging punching presses meet the diameter through hole 2 of welding copper pipe caliber, other end reducing is to the through hole 3 that meets the copper pipe weld size, for accurate soldering copper pipe, at main distributor and the punching press of copper pipe weld locations recessed bubble anchor point 4 is arranged, at the both ends of main distributor welding copper pipe.But copper pipe passed through recessed bubble anchor point easily when existing distributor heated in the actual welding with copper pipe, thereby can't guarantee location dimension; In addition, locate the distributor wall thickness at recessed bubble point place, because the effect of extruding makes the wall thickness of this place's copper pipe less than original distributor wall thickness, in transportation, produce easily secondary refrigerant leakage, security-hidden trouble occurs.Distributor and copper pipe multi-point welding, workload is large, and efficient is lower.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the prior art defective, provides a kind of accurate positioning, without the allotter for air-conditioner pipeline connecting of coolant leakage hidden danger.

The technical scheme that the utility model adopts is: a kind of allotter for air-conditioner pipeline connecting comprises main distributor; An end enlarging of described main distributor be formed with two with the suitable through hole of copper pipe caliber, the other end reducing of main distributor is formed with the single hole suitable with copper pipe; Be formed with the terrace with edge positioning ring groove at described main distributor both ends and copper pipe weld.

Described terrace with edge positioning ring groove is around the outer peripheral face of main distributor.

The beneficial effects of the utility model are: owing to be formed around with the terrace with edge positioning ring groove at the place, location of main distributor outer peripheral face, distributor is increased with cooperating copper pipe location contact area, during weld heating, copper pipe is not easy to pass through the terrace with edge locating slot, eliminated effectively that the point location in the processing position fixing process also makes the location dimension more accurate to the damage of copper pipe wall thickness in the prior art, welding quality is more stable, avoid coolant leakage hidden danger, promoted product quality.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done into lower detailed description:

Such as showing of Fig. 4-Fig. 6, the utility model allotter for air-conditioner pipeline connecting comprises, main distributor 10; An end enlarging punching press of main distributor 10 be formed with two with the suitable through hole 11 of copper pipe caliber, the other end of main distributor 10, reducing is formed with the single hole 12 suitable with copper pipe, distributor is that refrigerant flowed out from two through hole after a single hole flowed into coolant distribution, namely, distributor is " Y " type minute stream mode, and arrow points wherein is the direction that refrigerant flows; Be formed with terrace with edge positioning ring groove 13 at main distributor 10 both ends and copper pipe weld, described terrace with edge positioning ring groove 13 is around the outer peripheral face of main distributor 10, terrace with edge positioning ring groove 13 can make distributor and cooperate copper pipe location contact-making surface larger, it changes to ring surface supporting and location power f by existing some supporting and location power F, eliminated in the prior art, point location during the processing location has effectively been avoided leakage hidden danger to the damage of copper pipe wall thickness; Simultaneously, reduced the operation of stamped female bubble anchor point, improved production efficiency, also made location dimension more accurate, welding quality is more stable, has avoided leakage hidden danger, has promoted product quality.

It is worthy of note; protection domain of the present utility model is not limited to above-mentioned instantiation mode; according to basic fundamental design of the present utility model; also available essentially identical structure; can realize the purpose that this is novel; as long as those of ordinary skills need not through creative work, the embodiment that can associate all belongs to protection domain of the present utility model.
