The specific embodiment
Based on problems of the prior art, the utility model looks for another way, its core is to be optimized improvement for the connecting hole of welded unit in prior art, a kind of welded unit of effectively guaranteeing that insertion end external diameter matches with the connecting hole internal diameter size of link is provided, and improves weld strength and air-tightness.Another core of the present utility model is to provide a kind of valve body.
In order to make the operating personnel of the art understand better the utility model scheme, below in conjunction with Figure of description, the utility model is described in further detail.
Refer to Fig. 4, Fig. 5 and Fig. 6, wherein, Fig. 4 is the structural representation of the connecting hole in welded unit described in the specific embodiment; Fig. 5 is the axial cutaway view of connecting hole shown in Fig. 4; Fig. 6 is the structural representation of taking in welded unit described in the specific embodiment.
The welded unit that the utility model provides, comprises link 12 and the insertion end 21 coordinating with connecting hole 13 plug-in mountings of described link 12.Interference fit between the interior perimeter surface of this connecting hole 13 and the outer surface of insertion end 21, shown in Fig. 4 and Fig. 6, the interior perimeter surface of connecting hole 13 is provided with a plurality of inner fovea parts of accommodating scolder, so, can effectively evade the insertion end 21 of butt tube 2 in prior art and process processing, thereby eliminate to take over the phenomenon of 2 outside dimensions distortion, to guarantee to take over the reliable fit of 2 insertion end 21 and the connecting hole 13 of valve body 1.
And the interior perimeter surface processing of connecting hole 13 inner fovea part for valve body 1, only needs to adopt corresponding drift to process processing, without set special-purpose equipment for processing technology.So, can significantly cut down finished cost, and can guarantee under the fit dimension of connecting hole 13 connecting hole 13 of convenient easy processing valve body 1.
Known in conjunction with Fig. 5, projection between adjacent two inner fovea parts contacts with the outer surface of taking over 2, formation interference fit connects, limit valve body 1 and take over the relative position between 2, can eliminate in welding process and adopt auxiliary clamp to support the complicated procedures of forming of taking over 2, strong fix, thereby, simplify welding process, effectively improve welding production efficiency.Meanwhile, when valve body 1 coordinates with connecting hole 13 plug-in mountings, between insertion end 21 outer surfaces of the inner fovea part of connecting hole 13 and adapter 2, form the gap of filling scolder, to guarantee that sufficient scolder is distributed in the surrounding of welded unit, improve the reliability of welding.
It should be noted that, inner fovea part can be specially straight burr, or burr 131.But, inner fovea part be not only confined to this, this inner fovea part can be realized the interference fit of connecting hole 13 and insertion end 21, and version that can accommodating scolder all can.
In order to illustrate present embodiment, the inner fovea part in this programme is specially the version of burr 131, shown in Fig. 4 and Fig. 5.
Further, connecting hole 13 is provided with the guide angle inserting for insertion end, on the axial direction of connecting hole 13, burr length L 3 is less than connecting hole length L 4, that is to say, the axial direction that burr length L 3 directions and connecting hole 13 be set is in the same way, and, make this burr 131 lower than the inner side certain length of connecting hole 13 ports.Obviously, when assembling press-fits, can be convenient to insertion end inserts in connecting hole smoothly, the inflow that is conducive to scolder is filled, simultaneously, can guarantee to be filled in and take over 2 and be connected the scolder at position with valve body 1 in weld seam, avoid extending out non-insertion end 21 positions to adapter 2, thereby promoted the aesthetic property of welded unit outward appearance.
In addition, the inner fovea part degree of depth is arranged between 0.05-0.2mm.In this programme, the summit that the burr 131 of take protrudes position is set to 0.08mm as example to the radial distance between connecting hole 13 inner surfaces, and certainly, can be understood as burr height H is 0.08mm.
It should be noted that inner fovea part depth value refers to the peak position of the formed inner fovea part of connecting hole 13 inner surface and the distance between lowest point.Therefore, for burr 131, can be understood as burr height H.Particularly, the inner fovea part degree of depth is to set according to the relevant parameter of connecting hole 13, and the parameters such as the diameter of Main Basis connecting hole 13, material are determined.Certainly, inner fovea part depth value is more more conducive to scolder fills, and contributes to improve the intensity of welding.Consideration based on factors such as practical application and process operations, when the quantity of the inner fovea part of setting is more, can suitably reduce the inner fovea part degree of depth, when the negligible amounts of the inner fovea part of setting, can increase the inner fovea part degree of depth.
Further, inner fovea part is uniformly distributed in the interior perimeter surface of connecting hole 13 so that valve body 1 with take over 2 junctions even weld be distributed in this welded unit circumferentially, thereby effectively improve valve body 1 and the reliabilities of taking over 2 welding.
For the adapter 2 in welded unit, the outer peripheral face of its insertion end 21 is the circumferential surface coordinating with inner fovea part.Compared with prior art, the insertion end 21 of this adapter 2 is processed processing without employing special equipment, thereby can avoid the distortion of insertion end 21, guarantees valve body 1 and takes over effective cooperation the between 2.
Except above-mentioned welded unit, the utility model also provides a kind of valve body 1, this valve body 1 is provided with the connecting hole 13 coordinating with the insertion end 21 of taking over 2, and, interference fit between the interior perimeter surface of connecting hole 13 and the outer surface of insertion end 21, the interior perimeter surface of connecting hole 13 is provided with a plurality of inner fovea parts of accommodating scolder.
Further, in order to promote the manufacturability of processing valve body 1 during inner fovea part, and guarantee the reliability of valve body 1 service behaviour, this valve body 1 is block copper material.Meanwhile, the adapter 2 coordinating with valve body 1 is copper pipe or stainless steel tube.
Optimal Structure Designing for this valve body 1 can be referring to the elaboration to welded unit, and meanwhile, other part-structures of valve body 1 please refer to prior art, repeat no more herein.
It should be noted that, the valve body of only take is herein example with the position of taking over welding mutually, is understandable that, this welded unit is not limited in being connected of the connecting hole of valve body and the insertion end of adapter, is equally applicable to the connection that is welded to each other of two parts of above-mentioned form.
To welded unit provided by the utility model and with the valve body that adapter is welded to connect, be described in detail above.Only for object lesson of the present utility model, set forth herein, the explanation of above specific embodiment is just for helping to understand method of the present utility model and core concept thereof.It should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model feature, if can also make these improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
