Abstract
The invention discloses the sintering manufacturing process of a kind of acidproof ball valve core, belong to valve manufacture field.The sintering manufacturing process of this acidproof ball valve core comprises the following steps: select materials, pressure ball process, sintering processes, insert interior straight tube, polish, clean, the step such as spray-on coating, reliable by processing technique, it is achieved finished product spool is more reliable.
Description
Technical field
The present invention relates to valve manufacture field, the sintering manufacturing process of a kind of acidproof ball valve core.
Background technology
Valve is widely used in modern society.Particularly in water heating pipe fittings technical field, the valve of prior art has
A variety of, mainly there are ball valve, angle valve, stop valve etc., wherein ball-valve structure is relatively simple, and the mainly spool of ball valve is simpler
Single.The spool of ball valve chondritic the most symmetrically, there is the cylindric through hole of a through entirety centre, outside spool
Sphere centre position laterally has the valve rod groove that is connected with valve rod, and the when of work, rotation valve rod makes the cylinder of spool
The import and export of shape through-hole alignment ball valve, the when of quitting work, rotate backward the turnover that valve rod makes the sphere alignment ball valve of spool
Mouthful.Relatively simple for structure due to ball valve, easy to operate.So applying widely at valve technology field.And realize ball
The major part of the sealing function of valve is spool, and the sealing ring coordinated with it, and the spool of ball valve abrasion occurs or just ruptures
Easily reveal, make whole ball valve scrap, therefore improve the sintering manufacturing process of acidproof ball valve core so that it is more reliable just
Seem particularly necessary.
Summary of the invention
It is desirable to provide the sintering manufacturing process of a kind of acidproof ball valve core, reliable by processing technique, it is achieved to become
Product spool is more reliable.
For achieving the above object, technical scheme is as follows:
The sintering manufacturing process of a kind of acidproof ball valve core, it is characterised in that comprise the following steps:
Select materials: the iron powder of choice of powder shape is major ingredient, participate in accounting and weigh the granular size of 1/3 316 rustless steels at 110 ~ 150 mesh
As blank, it is placed in die of press.
Pressure ball processes: open forcing press, and the iron powder in mould and stainless steel material are suppressed glomerate spool blank.
Sintering processes: the spool blank that pressure ball obtains after processing is placed in 550 DEG C ~ 650 DEG C to carry out preheating 30 minutes, reheats
To 1000 DEG C ~ 1400 DEG C, persistently sintering more than one hour, finally slowly cools to room temperature.
Insert interior straight tube: after having sintered, selection is led to and external diameter is less than 316 stainless steel tubes of spherical shell latus rectum, incite somebody to action
It cuts into isometric with spherical shell latus rectum, uses straight tube in the tapered punch punching press expansion on punch press or stamping machine, make interior directly
Pipe and spherical shell are fixed together and form finished product spool；
Polishing: carry out surface polishing, sanding burr totally and is polished；
Clean: the spool made is put in acid solution, keeps 15 minutes, finally take out and rinse；
Basecoat paint: to surface spraying/roller coating prime paint, prime paint is white fused alumina sand grains, and is dried 30 minutes；
Surface lacquer sprays: at prime paint surface laser spraying of wearable coating, described wear-resistant coating is tungsten carbide coating, is dried 0.5-
After 1.5 hours, repeat to spray three times.
Further, built-in pipe step is inserted after obtaining spherical shell, in the centre position of spherical case surface described in
Open vertical masonry joint backlash and extrude valve rod groove, or output valve rod groove at the centre position milling cutter of spherical case surface.
The beneficial effects of the present invention is: use 316 rustless steels, can effective anticorrosive oxidation, it is to avoid spool is at specific ring
The problem that in border, service life shortens, have employed acid solution and is carried out, and goes out the iron filings on top layer, is allowed to more attractive.The present invention
Manufacture method the most significantly save material, reduce the cost of ball valve core；And the ball valve core precision made, thickness
Degree, integrity can be guaranteed, and valve rod connects the intensity of seat and valve rod junction and is improved.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
The sintering manufacturing process of a kind of acidproof ball valve core, comprises the following steps: select materials: the iron powder of choice of powder shape is main
Material, participates in accounting and weighs the granular size of 1/3 316 rustless steels at 110 ~ 150 mesh as blank, be placed in die of press.Pressure
Ball processes: open forcing press, and the iron powder in mould and stainless steel material are suppressed glomerate spool blank.Sintering processes: pressure
The spool blank that ball obtains after processing is placed in 550 DEG C ~ 650 DEG C to carry out preheating 30 minutes, is again heated to 1000 DEG C ~ 1400 DEG C, holds
Continuous sintering more than one hour, finally slowly cools to room temperature.Insert interior straight tube: after having sintered, selection is led to and external diameter is little
In 316 stainless steel tubes of spherical shell latus rectum, it is cut to isometric with spherical shell latus rectum, uses on punch press or stamping machine
Straight tube in tapered punch punching press expansion, makes interior straight tube and spherical shell be fixed together and forms finished product spool；Described built-in pipe walks
Rapid after obtaining spherical shell, open a vertical masonry joint backlash in the centre position of spherical case surface and extrude valve rod groove, or spherical
Valve rod groove outputed by the centre position milling cutter of case surface.Polishing: carry out surface polishing, sanding burr totally and is polished；Clearly
Wash: the spool made is put in acid solution, keep 15 minutes, finally take out and rinse；Basecoat paint: to surface spraying/rolling
Priming operation paint, prime paint is white fused alumina sand grains, and is dried 30 minutes；Surface lacquer sprays: at prime paint surface laser spraying abrasion-proof
Coating, described wear-resistant coating is tungsten carbide coating, after being dried 0.5-1.5 hour, repeats to spray three times.
The present invention uses 316 rustless steels, has acidproof characteristic, it is to avoid spool is shortening in service life in specific environment
Problem, have employed acid solution and is carried out, and goes out the iron filings on top layer, is allowed to more attractive.The manufacture method of the present invention is the most significantly
Save material, reduce the cost of ball valve core；And the ball valve core precision made, thickness, integrity can obtain
Ensureing, valve rod connects the intensity of seat and valve rod junction and is improved.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
