The specific embodiment
Below in conjunction with specific embodiment, technology of the present invention is described.
Fig. 1 is the structural representation of the collecting pipe component that provides of the present invention, and Fig. 2 is the structural representation of main discharge, and Fig. 3 is the structural representation of big envelope.
Such as Fig. 1, Fig. 2 and shown in Figure 3.Collecting pipe component 107 as agent structure, is processed with several step 11 at the tube wall of main discharge 1 by main discharge 1, and the employing straight tube structure that main discharge 1 can be as shown also can be according to connecting needs at one end or the two ends bend pipe.
According to the needs that air-conditioning system connects, the arm 2 of design processing different spaces structure, as in the present embodiment, arm 2 is the different bent tube type (certainly also can be straight pipe type) of angle of bend.One end of arm 2 is deep into the interior enforcements welding of step 11 of this main discharge 1 affixed (such structure is convenient to welding procedure in the disposable stove of each parts, then will introduce in detail).
End at main discharge 1 has expansion mouth 12, consists of scolder accommodation section 13 at the end of expansion mouth 12 by the chamfering form.Fairlead 3 extend into this expansion mouth 12 interior enforcements welding affixed (such structure is convenient to welding procedure in the disposable stove of each parts, then will introduce in detail).
Tubular big envelope 4 comprises hermetic terminal 41 and is connected the circumferential part 42 that cooperates with the pipe outer wall of main discharge 1, is provided with scolder accommodation section 43 at the end of circumferential part 42.In the present embodiment, the accommodation section 43 of big envelope 4 is by the end formation of falling the interior angle at circumferential part 42, certainly also can as shown in Figure 4, obtain accommodation section 43 by material expanding method.
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 larger like this, and corrosion-resistant reliable.Certainly, main discharge also can adopt carbon steel material to make, and improves its corrosion resistance by electro-plating method; Same arm can adopt Steel material to make, and improves its corrosion resistance by method for electroplating surface.
Fairlead of the present invention preferably adopts the material consistent with air-conditioning duct spare to make, and is convenient to so follow-up and the convenience that is welded to connect air-conditioning duct spare, fairlead can adopt straight tube also with the structure of bend pipe.
Big envelope of the present invention preferably adopts the material consistent with main discharge to be convenient to be welded to connect reliability.Certainly, when main discharge adopted stainless steel or carbon steel material, big envelope also can adopt copper material to be convenient to be connected with the copper pipeline fitting of system.
Fig. 5 is the preferred collecting pipe component assembling flow path of the present invention figure.
As shown in Figure 5.The preferred combined method of collecting pipe component of the present invention is as follows:
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, quite (main discharge also can be according to the assembling needs for the endoporus aperture of boss 11 and the outer Circular Aperture of arm 2, carrying out bend pipe processes), end processing enlarging 12 at main discharge 1, the endoporus aperture of its enlarging 12 is suitable with the outer Circular Aperture of fairlead 3, and forms accommodation section (certainly, also can not process the accommodation section) in the end of enlarging 12 by chamfering or flared method.
Process on request some arms 2 of given shape, 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 sealing cap 4, the endoporus aperture of the circumferential part 42 of sealing cap 4 is suitable with the outer Circular Aperture of main discharge 1, and it is certain to form accommodation section 43(in the end of circumferential part 42 by chamfering, also can not process the accommodation section).
Adopt the materials processing fairlead 3 consistent with air-conditioning duct spare.Certainly, fairlead 3 can namely 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 by interference or interference fits mode, fairlead 3 is inserted in the enlarging 12 of main discharge 1 by interference or interference fits mode, by interference or interference fits mode sealing cap 4 is inserted on the pipe outer wall of main discharge 1.Main like this discharge 1, arm 2, fairlead 3 and sealing cap 4 have been finished 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 respectively the weld-ring 202 of high temperature melting material at main discharge 1 and the connecting portion of arm 2, fairlead 3 and sealing cap 4.Namely respectively referring to Fig. 6 A, Fig. 6 B and Fig. 6 C, be inserted in weld-ring 202 at the arm 2 of vertically placing, and weld-ring 202 is inserted in the accommodation section 13 of the main discharge 1 of laterally placing; Weld-ring 202 is inserted in accommodation section 43 at the sealing cap of laterally placing.Because it is mobile that the accommodation section effect is difficult for weld-ring 202, is convenient to follow-up delivering to by the driving-chain mode and carries out soldering in the stove.
Need to prove that sealing cap 4 and main discharge 1 also can not process the accommodation section, like that, as shown in Figure 9, tilting frock can be set, it is mobile that weld-ring 202 is difficult for, and is convenient to follow-up delivering to by the driving-chain mode and carries out soldering in the stove.
Step 4: deliver to by the discharge sub-assembly of driving-chain mode after with pre-determined bit and to carry out soldering in the stove, form the collecting pipe component of the gas collection chamber with airtight connection.
Step 5: at the terminal welding procedure sealing cap of fairlead 3, collecting pipe component is filled with detection gas carries out Leak Detection.
In this combined method, preferably main discharge, arm, fairlead and sealing cap are soldered into by disposable stove.Equally, also can only main discharge, arm and fairlead be welded by disposable stove, have equally useful effect, not repeat them here.
In said structure and combined method, because main discharge, arm and sealing cap 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, be convenient in the stove weldering, control temperature range, the disposable stove weldering of collecting pipe component can be realized.
It below only is the preferred embodiment that exemplifies for setting forth technical scheme of the present invention; 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 improvements and modifications, all these improvements and modifications also should be considered as protection scope of the present invention.
