Description
Technical field
The present invention relates to valve manufacture field, specifically a kind of antirust valve element manufacturing process.
Background technology
Valve is widely used in modern society.Particularly in water heating pipe fittings technical field, the valve of prior art has
Many kinds, mainly have ball valve, angle valve, stop valve etc., wherein ball-valve structure is relatively simple, and the valve element of mainly ball valve is simpler
Single.The valve element of ball valve chondritic symmetrically on the whole, there is the overall cylindric through hole of an insertion centre, outer in valve element
The valve rod groove that is connected with valve rod is laterally had, when work, rotation valve rod makes the cylinder of valve element at sphere centre position
The import and export of shape through-hole alignment ball valve, when quitting work, rotating backward valve rod makes the sphere of valve element be directed at the turnover of ball valve
Mouthful.Relatively simple for structure due to ball valve, easy to operate.So applying widely in valve technology field.And realize ball
The major part of the sealing function of valve is valve element, and the sealing ring coordinating with it, and the valve element of ball valve abrasion or just ruptures
Easily reveal, so that whole ball valve is scrapped, therefore improve antirust valve element manufacturing process so as to more reliable just seem particularly must
Will.
Content of the invention
The present invention is intended to provide a kind of antirust valve element manufacturing process, reliable by processing technique, realize finished product valve element and more may be used
Lean on.
For achieving the above object, technical scheme is as follows：
A kind of antirust valve element manufacturing process is it is characterised in that comprise the following steps：
Sorting：From 304 stainless steel materials as blank, Size calculation is carried out according to valve element size, then use cutting machine according to
Blank is cut by the target size after calculating；
Solution treatment：By with process after pipe carry out solution treatment, 1050 DEG C of keeping temperature, 15 minutes persistent period, then
Quick cooling；
Drawing：Blank is placed on mould, opens clapper die spotting press, be warming up to 550 DEG C ~ 650 DEG C, carry out first time Hot drawing, first
Carry out above-mentioned solutionizing step again after secondary Hot drawing, then blank be placed in mould carrying out second Hot drawing, by secondary hot-drawn
After depth, blank carries out third time Hot drawing school shape until obtaining regular spherical shell, is protected in third time Hot drawing school shape
Pressure is processed；
Insert interior straight tube：From in logical and external diameter be less than 304 stainless steel tubes of spherical shell latus rectum, be cut to outer with spherical
Shell latus rectum is isometric, using straight tube in the tapered punch punching press expansion on punch press or stamping machine, so that interior straight tube is connected with spherical shell
Form finished product valve element together；
Polishing：Carry out surface polishing, sanding burr totally and is polished, then carry out the active group of flame treatment or corona discharge
Surface treatment, to strengthen surface adsorption ability；
Basecoat paint：To surface spraying/roller coating prime paint, prime paint is white fused alumina sand grains, by the above-mentioned embryo through basecoat paint
Part is thermally dried process 30 50min, and the temperature of heating is maintained at 60 80 degrees Celsius, then dried blank is entered
Row polishes process；
Surface lacquer sprays：In prime paint surface laser spraying of wearable coating, described wear-resistant coating is tungsten carbide coating, and 0.5- is dried
After 1.5 hours, repeat to spray three times.
Further, described drawing step, after obtaining spherical shell, opens one in the centre position of spherical case surface
Vertical masonry joint backlash extrudes valve rod groove, or outputs valve rod groove in the centre position milling cutter of spherical case surface.
Further, described drawing step, in forming process, needs after each drawing the drawing state of part is carried out
Observation, need to carry out smoothing wrinkle process if there is fold, then carry out drawing next time.
The beneficial effects of the present invention is：Using 304 rustless steels, can effectively anticorrosive oxidation, it is to avoid valve element is in specific ring
The problem that in border, service life shortens, employs acid solution and is carried out, and the iron filings on top layer of going out are allowed to more attractive.The present invention
Manufacture method not only significantly save material, reduce the cost of ball valve core；And the ball valve core precision making, thickness
Degree, integrity can be guaranteed, and the intensity of valve rod connecting seat and valve rod junction is improved.
