Background technique
In refrigeration industry, adopt welding between connecting tube and the pipe joint that is connected usefulness, welding manner commonly used is manual welding and two kinds of welding automatically.In the manual welding mode, there is the low and uppity shortcoming of quality of efficient, particularly for the tubule footpath connecting tube of φ below 6, stifled problem appears welding in manual welding easily.
The mode that automatic soldering technique adopts at present is shown in Fig. 1 a and 1b; A sheathed weld-ring 30 on connecting tube 20; Again sheathed behind the connecting tube 20 insertion tube joints 10 of weld-ring 30; Heat whole or parts to the connecting tube of pipe joint 10 and sheathed weld-ring 30 20, makes weld-ring 30 fusing backs flow into the gap between connecting tubes 20 and the pipe joint 10, thereby realize connection.Present pipe joint is shown in Fig. 2 a, 2b, 3a, 3b, and an end of pipe joint has cannula port 11.
Automatically welding has improved welding efficiency and welding quality; But present automatic welding manner also has deficiency: with sheathed behind the connecting tube 20 insertion tube joints 10 of weld-ring 30; Need the position of adjustment weld-ring 30, make weld-ring 30 be positioned at pipe joint 10 upper edges, with the stroke of control scolder; And then heat welded, the operation of adjustment weld-ring position has reduced manufacturing efficiency.In addition, the position of weld-ring also is difficult for confirming in the process of adjustment weld-ring position, if the weld-ring position is too high; Then can cause the flow of solder material stroke long; Scolder is not in place, causes fusion penetration not enough, reduces welding quality; Be easy to generate leakage, the operation of adjusting the weld-ring position has simultaneously also reduced manufacturing efficiency.
The model utility content
The utility model aims to provide a kind of air conditioner and dehumidifier that improves the pipe joint of welding manufacturing efficiency and have it, needs the problem of adjustment weld-ring position before to solve weld heating.
The utility model provides a kind of pipe joint; First end of pipe joint has the cannula port that extends axially and be used for cooperating with connecting tube along it; Cannula port is provided with annular weld-ring receiving groove towards the opening end of connecting tube, and the internal diameter of weld-ring receiving groove is greater than the internal diameter of cannula port.
Further, pipe joint also comprises the transition cone hole part that is arranged between cannula port and the weld-ring receiving groove.
Further, the end face of pipe joint first end has circular step, and the weld-ring receiving groove is arranged on the circular step.
The utility model also provides a kind of air conditioner, comprises aforesaid pipe joint.
The utility model also provides a kind of dehumidifier, comprises aforesaid pipe joint.
According to the pipe joint of the utility model, be provided with the weld-ring receiving groove in the end of cannula port, during welding; Earlier weld-ring is put into the weld-ring receiving groove, and then insert connecting tube, need not adjust the position of weld-ring during welding; Thereby the saving operation improves welding manufacturing efficiency.

Embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.
As shown in Figs. 4a and 4b; Pipe joint according to the utility model; First end of pipe joint has the cannula port 11 that extends axially and be used for cooperating with connecting tube 20 along it; Cannula port 11 is provided with annular weld-ring receiving groove 12 towards the opening end of connecting tube, and the internal diameter of weld-ring receiving groove 12 is greater than the internal diameter of cannula port 11.During welding, earlier weld-ring 30 is put into weld-ring receiving groove 12, and then insert connecting tube 20.The pipe joint 10 that is provided with so need not adjusted the position of weld-ring 30 during welding, thereby practices thrift operation, improves welding manufacturing efficiency.
Preferably, pipe joint also comprises the diameter that is arranged between cannula port 11 and the weld-ring receiving groove 12 cone hole part 13 that increases of transition gradually.After the heating, weld-ring 30 fusings, cone hole part 13 makes melting solder flow into the gap between cannula port 11 and the connecting tube 20 quickly and easily, guarantees welding quality.
According to another embodiment of the utility model, shown in Fig. 4 b, the end of pipe joint first end has circular step 14, and weld-ring receiving groove 12 is arranged on the circular step 14.Adopt the design of circular step 14; In material saving, deepened the degree of depth of cannula port 11; Guarantee that pipe joint 10 and connecting tube 20 have enough length of thread engagement; And increase scolder and flow into the Clearance Flow stroke between cannula port 11 and the connecting tube 20, make welding more reliable, effectively prevent to weld defective leakage.In addition, change the degree of depth of cannula port 11, can adjust the relative position of weld-ring receiving groove 12; With control flow of solder material stroke, can prevent the mouth of pipe place of the end of too much flow of solder material to connecting tube 20, thereby prevent that weldering is stifled; Be prone to the stifled defective of weldering thereby overcome under the situation of tubule footpath, after welding quality is guaranteed, can widen the specification of pipe joint 10; Increase the pipe joint specification that the tubule footpath connecting tube of φ below 6 used, help the miniaturization development of this pipe joint.
Preferably, circular step 14 adaptive, and length of thread engagement is moderate with connecting tube, the degree of depth of circular step can not be crossed deeply also can not be shallow excessively, and dark excessively pipe is taken over most of ring-shaped step that inserts, and causes waste of material; The shallow excessively pipe joint of circular step and the welding degree of depth of ring-shaped step are not enough.
Shown in Fig. 5 a, 5b; The pipe joint of the utility model and the welding method of connecting tube; May further comprise the steps: the weld-ring receiving groove 12 of at first weld-ring 30 being put into aforesaid pipe joint 10; Then connecting tube 20 is passed in the cannula port 11 of weld-ring 30 and insertion tube joint 10, accomplish assembling, again the pipe joint that assembles 10, connecting tube 20, weld-ring 30 are sent into the automatic welding machine welding.
The utility model also provides a kind of air conditioner and dehumidifier that comprises the aforementioned tubes joint.Adopt aforesaid pipe joint 10 and connecting tube 20 welding, weld-ring 30 is placed in the weld-ring receiving groove 12, makes things convenient for the location of weld-ring 30, does not need to adjust once more the position of weld-ring 30, thereby reduces operation, improves the efficient of assembly process.In addition, the fixed-site of weld-ring 30, thus can effectively control the stroke of flow of solder material, guarantee that the connecting tube and the welding of pipe joint fuse the degree of depth.Can prevent that also too much stacked solder from causing weldering stifled at connecting tube 20 mouth of pipe places.
From above description, can find out that the utility model the above embodiments have realized following technique effect:
According to the pipe joint of the utility model and have its air conditioner and dehumidifier, be provided with the weld-ring receiving groove in the end of cannula port, during welding, earlier weld-ring is put into the weld-ring receiving groove, and then insert connecting tube.The pipe joint that is provided with like this, the weld-ring fixed-site need not adjusted the position of weld-ring during welding; Thereby the saving operation improves welding manufacturing efficiency, the weld-ring fixed-site; Also help controlling the mobile stroke of fusing back scolder, improve welding quality, prevent that weldering from leaking and weldering is stifled.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
