Utility model content
The utility model aims to provide a kind of pipe joint welding nitrogen charging device, to solve when welding pipe joint, easily producing shake, causing pipe joint to split the hidden danger of quality of leakage; And when carrying out high-temperature soldering to pipe joint, easily produce oxide skin in copper pipe inside, cause producing in air-conditioning system inside leaking stifled hidden danger.
To achieve these goals, the utility model provides a kind of pipe joint welding nitrogen charging device, and principal character is that it comprises: discharge; Pipe joint, described pipe joint is connected with one end of described discharge; Fill nitrogen mould: described in fill nitrogen mould upper end be provided with groove, bottom is provided with can for the through hole of nitrogen circulation.Fill the groove of nitrogen mould described in described pipe joint embeds, nitrogen fills the through hole in nitrogen mould by described and be full of copper pipe.
Further, the cross sectional shape filling the groove of nitrogen mould upper end described in is hexagonal.
Further, the cross sectional shape filling the groove of nitrogen mould upper end described in is quadrangle, pentagon, circle.
Further, the through hole filling nitrogen mould bottom described in runs through whole and fills nitrogen mould.
Further, discharge is connected by the mode of welding with pipe joint.
Further, described in fill nitrogen mould be cylindrical, and the diameter of upper end is greater than the diameter of bottom.
Further, the material of filling nitrogen mould described in is stainless steel.
Application the technical solution of the utility model, when welding pipe joint, pipe joint can firmly put into the groove filling nitrogen mould, effectively ensure that the stability of pipe joint in welding process, reduce the scrappage of Product jointing, reduce cost, improve the welding quality of pipe joint.Of the present utility modelly filling nitrogen mould, pipe joint can also being realized when carrying out high-temperature soldering, adopt nitrogen filled protection, avoid copper pipe inside to produce oxide skin, eliminate air-conditioning built-in system and leak stifled hidden danger of quality.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 diagrammatically illustrates the schematic diagram of pipe joint welding nitrogen charging device in the utility model;
Fig. 2 diagrammatically illustrates the sectional view filling nitrogen mould in the utility model;
Fig. 3 diagrammatically illustrates in the utility model the structural representation filling nitrogen mould.
Detailed description of the invention
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
As shown in FIG., when welding discharge 1 and pipe joint 2, first discharge 1 is put into one end of pipe joint 2, then the other end of pipe joint 2 is put into fill in the groove 5 of nitrogen mould 4.Pipe joint so both can have been made to keep stability when welding; nitrogen can be made again through overcharging the through hole 6 of nitrogen mould 4 bottom; be full of whole discharge and pipe joint; thus realize when carrying out high-temperature soldering to copper pipe; the protection of copper pipe owing to there being nitrogen, and avoid the phenomenon producing oxide skin.
In an embodiment wherein, block and fill through hole in nitrogen mould 46 in order to effectively control flux powder and (need to increase scaling powder when brass connects red copper welding to weld, scaling powder can produce flux powder in welding process), the diameter of the through hole 6 filled in nitrogen mould 4 is increased to 6mm by spy.Such through hole 6 will be not easy to be blocked by flux powder, both decrease the time needing artificial constantly cleaning through hole, effectively ensure that again when welding, to the nitrogen protection of copper pipe.
In an embodiment wherein, during welding, place a weld-ring 3 at discharge and pipe joint junction, and use automatic welding machine to carry out automatic welding to discharge and pipe joint.Welding adopts welding gun preheating and welding 2 steps, after having welded, pipe joint can not cooled and solidified in time, after using welding of the present utility model to fill nitrogen mould, fill in the groove 5 of nitrogen mould 4 owing to pipe joint can be placed on completely, effectively can ensure the stability of pipe joint, effectively eliminate the Product jointing mass defect that solder joint splits leakage and generation.
In an embodiment wherein, described in fill the groove 5 of nitrogen mould 4 cross sectional shape be hexagon; Special
In an embodiment wherein, the cross sectional shape of groove is quadrangle, pentagon, circle.
In an embodiment wherein, described in fill the groove 5 of nitrogen mould 4 width range be 15mm to 28mm; Depth bounds is 15mm to 20mm; The described whole height filling nitrogen mould 4 is 50mm to 55mm, and the length range of through hole 6 is 15mm to 20mm.
In an embodiment wherein, described in fill nitrogen mould 4 and adopt stainless steel material to make.
From above description; can find out; the above embodiments of the present invention achieve following technique effect: weld nitrogen charging device by adopting pipe joint of the present utility model; make pipe joint when welding; achieve the nitrogen filled protection to pipe joint and steadiness during welding, decrease the trouble needing often cleaning nitrogen through hole, reduce the labour intensity of workman; effectively eliminate solder joint to split burst and fall into, improve the welding quality of pipe joint and the quality of product.
