Description
Technical field
The invention belongs to valve technology fields, are related to a kind of angle valve, especially a kind of angle valve and angle valve manufacturing process and fixed
Position tooling.
Background technique
Angle valve is exactly angle stop valves, is widely used in bathroom field.The water outlet and water inlet of angle valve are at right angle, in addition
One end is equipped with the handle that control angle valve opens or closes.Currently, the valve body of angle valve generallys use monoblock cast or seperated weldering
The technique processing connect.
The monoblock cast of angle valve, the mode for first passing through foundry casting make the valve body blank of angle valve, then to valve body blank into
Row heat treatment and surface treatment, then make valve body blank surface smoothness reach design requirement by polishing, finally by valve body and
The components such as spool are assembled to obtain angle valve finished product.Angle valve is led due to special structure, i.e. water outlet and water inlet at right angle
Cause water inlet segment and water outlet pipeline section also at right angle, foundry casting is more difficult, and rejection rate is higher.Also, the valve that foundry casting goes out
Chaeta embryo surface quality is also poor, carries out the technique such as polishing, complex process again adversely affects environment.With production
The progress of technology, foundry casting also because itself not meeting environmental requirement, are just eliminated rapidly.
The manufacturing process of another Split type welding, for example, Chinese patent [application number 201310703333.6；Application is public
Cloth CN103692164A] disclosed in a kind of triangle vavle and its manufacturing method, this method comprises: big according to required manufacture triangle vavle
The small inlet tube and outlet for cutting two sections of tubing and being used separately as triangle vavle, inlet tube include head end and end, and wherein head end is used
In placement spool；Inlet tube head end and end and one end of outlet are subjected to tapping process；On inlet tube, cartridge outlet
Corresponding position aperture；Outlet is welded to position of opening, later by triangle vavle overall surface polishing treatment；From inlet tube head end
Then middle assembly spool and fixation install hand grip control and obtain triangle vavle.
The manufacturing method of the triangle vavle of above-mentioned patent disclosure, by being made inlet tube and outlet respectively, then by inlet tube
Carried out by welding with outlet it is connected, and according to the content of the patent notes it is found that the weldering of inlet tube and outlet
Contact is located at outer surface, and welds completion later again by integrally being polished triangle vavle to guarantee surface smoothness.This
Kind welding procedure has problems in that: 1, since the junction of inlet tube and outlet is arc transition, pad is located at outer
Surface, even across polishing treatment, it can also be seen that the weld seam of inlet tube and outlet intersection, can not make to guarantee triangle vavle table
Face reaches ideal finish, causes triangle vavle surface conformance poor；2, identical as monoblock cast, three after Split type welding
Angle valve is integrally also required to be processed by shot blasting, the difficulty of polishing is bigger, increases production cost, while also not environmentally.
