The specific embodiment
Below in conjunction with specific embodiment, the technology of the utility model is described.
The structural representation of the discharge assembly that Fig. 1 provides for the utility model, Fig. 2 is the structural representation of main discharge, Fig. 3 is the structural representation of blocking.
Like Fig. 1, Fig. 2 and shown in Figure 3.Discharge assembly 107 as agent structure, is processed with several steps 11 by main discharge 1 on the tube wall of main discharge 1, main discharge 1 can be like illustrated employing straight tube structure, also can be according to the connection needs at one end or the two ends bend pipe.
According to the needs that air-conditioning system connects, the arm 2 of Design and Machining different spaces structure, as in the present embodiment, arm 2 is the different bent tube type (also can be straight pipe type certainly) of angle of bend.One end of arm 2 is deep into and implements welding affixed (such structure is convenient to welding procedure in the disposable stove of each parts, then will introduce in detail) in the step 11 of this main discharge 1.
End at main discharge 1 has expansion mouth 12, constitutes scolder accommodation section 13 at the end of expansion mouth 12 through the chamfering form.Fairlead 3 extend into and implements welding affixed (such structure is convenient to welding procedure in the disposable stove of each parts, then will introduce in detail) in this expansion mouth 12.
Fig. 4 is blocking and main discharge syndeton sketch map.Tubular blocking 4 is welded on the end of main discharge 1; And cooperate (such structure setting with the inwall of said main discharge; Be convenient to after main discharge 1 and arm 2 and fairlead 3 form weld assembly through furnace brazing; When making up with blocking 4 gas brazings again, can reduce the heat affecting of secondary welding).
In the present embodiment, main discharge preferably adopts the stainless steel material, and under identical wall thickness condition, the chamber pressure that can bear is bigger like this, and corrosion-resistant reliable.Certainly, main discharge also can adopt carbon steel material to process, and improves its corrosion resistance through electro-plating method; Same arm can adopt steel to process, and improves its corrosion resistance through methods such as electroplating surfaces.
The fairlead of the utility model preferably adopts the material consistent with air-conditioning duct spare to process, and is convenient to follow-up and the convenience that is welded to connect air-conditioning duct spare like this, fairlead can adopt straight tube also with the structure of bend pipe.Blocking of the present invention preferably adopts the material consistent with main discharge to be convenient to be welded to connect reliability.
Fig. 5 is the discharge assembly assembling flow chart of the utility model.
As shown in Figure 5.The preferred combined method of discharge assembly of the utility model is following:
Step 1: use stainless pipe tubing to process main discharge 1; Be included in stretch on the tube wall (flange) and go out several boss 11, the endoporus aperture of boss 11 and the cylindrical aperture of arm 2 be (main discharge also can carry out bend pipe and handle according to the assembling needs) quite; End processing enlarging 12 at main discharge 1; The endoporus aperture of its enlarging 12 is suitable with the cylindrical aperture of fairlead 3, and forms accommodation section (certainly, also can not process the accommodation section) in the end of enlarging 12 through chamfering or flared method.
Process some arms 2 of given shape on request; The material of arm 2 preferably uses carbon steel material and carries out copper plating treatment to be convenient to weld with the main discharge 1 of stainless steel material like this; Can certainly use copper material (as using copper material, just need not electroplating processes).
Use stainless steel or carbon steel material processing tubular blocking 4.
Adopt the materials processing fairlead 3 consistent with air-conditioning duct spare.Certainly, fairlead 3 can promptly adopt straight tube also with the structure of bend pipe.
Step 2: each arm 2 is inserted in the boss 11 of main discharge 1 through interference or interference fits mode; Fairlead 3 is inserted in the enlarging 12 of main discharge 1 through interference or interference fits mode, main like this discharge 1, arm 2 and fairlead 3 have been accomplished the pre-determined bit combination.
Step 3: referring to Fig. 6, the pre-determined bit sub-assembly is roughly lain on the machine frame 201, put into the weld-ring 202 of high temperature melting material respectively at the main discharge 1 and the connecting portion of arm 2 and fairlead 3.Promptly, on the arm of vertically placing 2, be inserted in weld-ring 202, and weld-ring 202 is inserted in the accommodation section 13 of the main discharge of laterally placing 1 respectively referring to Fig. 6 A and Fig. 6 B.Because the accommodation section effect makes weld-ring 202 be difficult for moving, and is convenient to follow-up delivering to through the driving-chain mode and carries out soldering in the stove.
Need to prove that main discharge 1 also can not process the accommodation section, that kind is as shown in Figure 9, and tilting frock can be set, and makes weld-ring 202 be difficult for moving, and is convenient to follow-up delivering to through the driving-chain mode and carries out soldering in the stove.
Step 4: deliver to through the discharge sub-assembly of driving-chain mode after and to carry out soldering in the stove, form weld assembly with pre-determined bit.
Step 5: sealing cap 4 is inserted on the inside pipe wall of main discharge 1 through interference or interference fits mode, forms the discharge assembly of gas collection chamber through gas brazing with airtight connection.
In this operation, because the tubular blocking is welded on the end of main discharge, and cooperates with the inwall of main discharge, certain distance is arranged apart from main discharge and Zhi Guanlu weldering link position, can reduce the heat affecting of secondary welding, improve the airtight reliability of welding.
Step 6:, the discharge assembly is charged into detection gas carry out leak detection at the terminal welding procedure sealing cap of fairlead 3.
In said structure and combined method; Because main discharge, arm and blocking all adopt carbon steel or stainless steel material; And the weld-ring of high temperature melting material adopts copper or silver-based material; Both molten temperature regions are different, are convenient in the stove weldering, control temperature range, can realize the disposable stove weldering of discharge assembly critical piece.
It below only is the preferred implementation of giving an example for the technical scheme that can better set forth the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, all these improvement and retouching also should be regarded as the protection domain of the utility model.
