Description
Technical field
The invention belongs to valve technology field, the linkage structure of turnover water pipe in particularly a kind of water tap.
Background technique
In water tap, one or two intake pipes and an outlet pipe are arranged generally.Intake pipe and outlet pipe all communicate with the valve body of water tap.Current enter the valve body from intake pipe, behind the spool in valve body, outwards flow out from outlet pipe.
In common structure, the turnover water pipe of water tap all is connected as a single entity with valve body.With outlet pipe and valve body integral cast, though this mode has solved the problem that both connect, and does not influence its outward appearance, the complex manufacturing of valve, also higher to the requirement of mould.Simultaneously, in case careless manipulation is scrapped with regard to causing easily in its production process, yield rate is not high, thereby causes the raising of cost of production.In addition, polishing and electroplating processes are also cumbersome.
For this reason, the someone adopts turnover water pipe and valve body is made respectively, and links together by welding manner, and then through polishing and plating.Though this mode is simple, exists many defectives:
Because surface temperature is very high, pore appears in workpiece easily in course of working, and conformity is poor when 1, adopting welding procedure;
2, by the surface irregularity of product after the welding procedure, polishing difficulty height makes the profile of product not attractive in appearance;
If 3, product surface local defectiveness after plating just needs to change whole valve body, cause cost of production to improve.
In addition, long term exposure is also damaged easily at the weld part of product surface, and shortened the working life of water tap.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of reasonable in design, simple in structure, outlet pipe is connected with valve body closely, the joint any surface finish, and the product quality height is easy to polish the linkage structure of the watertap discharging tube of plating; Having solved the existing outlet pipe of prior art and the joint of valve body, to be connected vestige obvious, has a strong impact on the quality of product, and it is big that difficulty is electroplated in polishing, and joint is technical problem such as fracture easily also.
Another object of the present invention is at the problems referred to above, provides a kind of fabricating cost cheap, saves material, make simple and convenient, the linkage structure of the watertap discharging tube that yield rate is high; It is comparatively loaded down with trivial details to have solved the existing in prior technology preparation process, and mould structure complexity, yield rate are not high, consumable quantity big, cost of production high-technology problem.
For achieving the above object, the present invention has adopted following technical proposal: the linkage structure of this watertap discharging tube, be arranged between the valve body and outlet pipe of water tap, osculum is arranged on the valve body, and osculum communicates with outlet pipe, it is characterized in that, the aperture of described osculum is provided with a connecting tube, connecting tube and valve body are connected, and are provided with a columnar back-up ring at the inner side surface of outlet pipe connecting end, and back-up ring and outlet pipe are connected; Be provided with a connecting body that both are connected between above-mentioned connecting tube and back-up ring, connecting body is cylindrical; Described shield ring sleeve is provided with the retaining edge that is used to block the back-up ring exterior edge face on connecting body outside connecting tube.
The present invention creatively is provided with connecting tube at the position of opening of osculum, and is connected with connecting tube and outlet pipe, and original attachment portion is included in the outlet pipe, so just can improve the quality of product effectively so that both connecting parts are smooth.
In the linkage structure of above-mentioned watertap discharging tube, described connecting tube is connected by welding and valve body.
In the linkage structure of above-mentioned watertap discharging tube, described back-up ring is connected with outlet pipe by welding or engage thread.Here can there be multiple embodiments being connected between back-up ring and the outlet pipe.
In the linkage structure of above-mentioned watertap discharging tube, described connecting tube and back-up ring are enclosed within respectively outside the connecting body, and described connecting body and connecting tube be by being threaded, and described connecting body and back-up ring are by being threaded.The connecting body outer wall here is provided with screw thread, respectively with the screw thread of inwall and being threaded of back-up ring inwall of connecting tube.
As another kind of scheme, in the linkage structure of above-mentioned watertap discharging tube, described connecting body and connecting tube are by being threaded.For example, screw thread is set, with being threaded of the outer wall of connecting tube at the connecting body inwall.
In the linkage structure of above-mentioned watertap discharging tube, described connecting body is provided with the screw thread of direction unanimity, and described connecting body is threaded with back-up ring and connecting tube successively.During assembling, connecting body is screwed in back-up ring and connecting tube successively, outlet pipe and valve body are connected with assembly tool.
As another kind of scheme, in the linkage structure of above-mentioned watertap discharging tube, described connecting body is provided with two sections screw threads that direction is opposite, and the one end is threaded with connecting tube, and the other end is threaded with back-up ring.During assembling, slightly with the end screw-in connecting tube of connecting body, its other end screws in back-up ring slightly earlier; With the special-purpose instrument body that is rotatably connected, because the hand of spiral difference on both sides, shrink simultaneously on both sides, thereby outlet pipe and valve body are connected then.
Also have a kind of scheme, in the linkage structure of above-mentioned watertap discharging tube, described back-up ring is placed on the connecting tube, and connecting body is connected with connecting tube by screw thread, and the outer end of connecting body is provided with the retaining edge, and described retaining is along being pressed on the exterior edge face of back-up ring.Utilize retaining along back-up ring is blocked,, thereby outlet pipe and valve body are connected owing to back-up ring is connected on the outlet pipe.
In addition,, prevent to leak, in the linkage structure of above-mentioned watertap discharging tube, be provided with ○Xing Mifengquan between described connecting body and the back-up ring in order to improve sealing.
Compared with prior art, the advantage of the linkage structure of this watertap discharging tube is:
1, reasonable in design, simple in structure, easy to implement, the yield rate height, preparation process is simple;
2, after water tap adopts structure provided by the invention, because connecting tube is connected by welding manner and valve body, so valve body can adopt common tubing to process, needn't the die sinking tool, thus greatly reduce production cost of products and material;
3, outlet pipe is connected closely with valve body, and be easy to polishing and electroplate, the joint any surface finish, product quality height, joint are difficult for causing damage, long service life;
4, after water tap adopts structure of the present invention, its good airproof performance, easy to leak does not have higher utility.
