Description
Technical field
The utility model relates to brass liquid-dividing head, is specifically related to a kind of brass liquid-dividing head assembly.
Background technology
Brass liquid-dividing head assembly is the main accessory using for separatory in air-source heat pump hot water group evaporimeter, and it is mainly welded by separatory house steward 4, liquid-dividing head 2, liquid-dividing head annex 3 and Duo Gen separatory arm 1, as shown in Figure 1.And the normal separatory arm using has the copper tube of TP2M φ 6.35 × 0.75, TP2M φ 4.8 × 0.65 equal-specifications, the separating tube caliber that some producers are used is even less.
In soldering, just occur that than being easier to separating tube weldering is stifled and separatory arm is less than normal, once occur that liquid-dividing head weldering is stifled, can affect the performance of whole unit.In welding process, bring difficulty to heating for reducing bulky liquid-dividing head, in the time of the pitch-row of design liquid-dividing head, make its compactness as far as possible, so also can save accordingly material cost.
The welding of existing separatory arm and liquid-dividing head is generally by each separatory weld-ring 5 being enclosed within on separatory arm one by one separately, in the time of welding, liquid-dividing head outer surface there will be overlap, and because weld-ring is less than normal, more loaded down with trivial details in being socketed on each separatory arm, increase a lot of workloads, simultaneously, for weld-ring being enclosed within to each separatory arm root, must must ensure the spacing between each circular hole and circular hole on liquid-dividing head, so just need to strengthen the external diameter of whole liquid-dividing head, cause liquid-dividing head overall dimensions larger, waste material, increases production cost.
Utility model content
The purpose of this utility model is to provide a kind of brass liquid-dividing head assembly, described brass liquid-dividing head assembly is provided with circular groove at liquid-dividing head head, by the weld-ring in circular groove and separatory branch pipe welding, liquid-dividing head can be done as far as possible little, larger in order to solve the spacing of existing liquid-dividing head head circular hole, cause liquid-dividing head size large, thereby cause the problem that production cost is high.
For achieving the above object, scheme of the present utility model is: a kind of brass liquid-dividing head assembly, described brass liquid-dividing head assembly comprises liquid-dividing head, one component liquid arm, liquid-dividing head annex and separatory house steward, the periphery of described liquid-dividing head head end is evenly provided with the circular hole equating with described separatory arm number, a described component liquid arm lays respectively in the circular hole that liquid-dividing head head is corresponding, fix as one with described liquid-dividing head head welding, described liquid-dividing head afterbody and the welding of the head of liquid-dividing head annex fix as one, the afterbody of described liquid-dividing head annex and separatory house steward welding fix as one, it is characterized in that:
The head end of described liquid-dividing head is provided with circular groove one, the lateral wall of described circular groove and each described circular hole join, in described circular groove, be provided with a weld-ring, described liquid-dividing head head fixes as one by the weld-ring and the each separatory branch pipe welding that are arranged in described circular groove.
According to brass liquid-dividing head assembly described in the utility model, described weld-ring is phosphor-copper weld-ring.
According to brass liquid-dividing head assembly described in the utility model, the head of described liquid-dividing head is umbrella-shaped structure.
The beneficial effect that the utility model reaches: (1) the utility model is due to without be all inserted in weld-ring on every separatory arm, can ensure that each separatory arm has a less caliber, and the pitch-row that liquid-dividing head head arranges is as far as possible compact, liquid-dividing head can do little as far as possible, can save accordingly material cost, meet production requirement.And adopt common phosphor-copper weld-ring, also greatly reduce welding material cost.
(2) the utility model only need to be placed a large weld-ring in the circular groove of liquid-dividing head head, has greatly saved labour, has improved production efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, welding method of the present utility model is described in more detail.
As shown in Fig. 2～Fig. 5, brass liquid-dividing head assembly of the present utility model comprises a component liquid arm 1, liquid-dividing head 2, liquid-dividing head annex 3 and separatory house steward 4, the periphery of described liquid-dividing head 1 head end is evenly provided with circular hole 7, one component liquid arm lays respectively in corresponding circular hole 7 and welds with liquid-dividing head head, described liquid-dividing head afterbody and the welding of the head of liquid-dividing head annex, the afterbody of described liquid-dividing head annex and separatory house steward welding, described liquid-dividing head head end is provided with circular groove 6 one, described circular groove 6 outsides and each circular hole join, described liquid-dividing head head welds with each separatory arm 1 by the weld-ring 8 being arranged in described circular groove 6.Weld-ring of the present utility model adopts phosphor-copper weld-ring, saves the cost of welding material.
The utility model is provided with the circular groove for placing weld-ring at the head of liquid-dividing head, when liquid-dividing head and separatory arm are welded, by welding position homogeneous heating, the scolder of fusing flows between every separatory arm mutually by circular groove, realize the welding of liquid-dividing head and separatory arm, without be all inserted in weld-ring on every separatory arm, can ensure that each separatory arm has a less caliber, meet production requirement, and owing to being all inserted in weld-ring without each separatory arm, the pitch-row that liquid-dividing head head arranges can be tried one's best compact, liquid-dividing head can do little as far as possible, reduce cost.
