Description

A kind of valve manufacture method
Technical field
The present invention relates to technical field of valve manufacturing, more particularly to a kind of valve manufacture method.
Background technology
Valve is widely used in modern society.The valve of prior art has many kinds, mainly has ball valve, angle valve, cuts Only valve etc., it is relatively simple for structure due to valve, it is easy to operate, so application is very extensive.
And the sealing function of valve is easily revealed once abrasion or rupture occurs, in fields such as combustion gas, oil gas once sending out Raw leakage, easily occurs security incident.Therefore, it is necessary to improve its sealing property in the production process of valve, it is possible to increase it makes With the life-span, the generation of leakage accident is reduced.
The content of the invention
The present invention solves the technical problem of a kind of valve manufacture method is provided, by changing the production technology of valve, To improve its service life.
To solve above-mentioned technical purpose, the technical solution adopted by the present invention is as follows：
A kind of valve manufacture method, it is characterised in that comprise the following steps：
A. it is major ingredient and alloy auxiliary material in mass ratio 10 to select iron:1 mixing, the alloy auxiliary material is Mo：2 parts, Cu：7.5 parts, W： 7.5 parts, Si：4.5 parts, Mn：1.5 part, Ti：7.5 parts, Se：4 parts, S：1 part, P：1 part mixes；
B. gained compound in step A is smelted respectively, blank is formed after hot rolling, and it is thick by being formed after cutting Embryo；
C. the thick embryo obtained to step B is heat-treated, and is machined out to obtain valve semi-finished product；
D. after the valve semi-finished product obtained to step C carry out modifier treatment, polished using emery wheel, deburring, utilize polishing machine Sealing surface is processed by shot blasting, obtains the surface of flat smooth；
E. painting wear-resistant coating is carried out to the smooth surface of valve obtained by D steps, the wear-resistant coating is tungsten carbide coating.
Further, the wear-resistant coating in the E steps is dried 30 minutes after Puttying, and roller coating surface mark applies Layer.
Further, the modifier treatment in the D steps includes multiple normalized treatment and a temper.
Further, the temper gradually heats mode using segmented and heated, every section keep 10 minutes with Upper heating duration.
The beneficial effects of the invention are as follows：The situation of prior art is different from, its service life of the valve of present invention gained is longer, Sealing effectiveness is more preferable.
Embodiment
The present invention is described further with reference to specific embodiment.
A kind of valve manufacture method, comprises the following steps：
A. it is major ingredient and alloy auxiliary material in mass ratio 10 to select iron:1 mixing, the alloy auxiliary material is Mo：2 parts, Cu：7.5 parts, W： 7.5 parts, Si：4.5 parts, Mn：1.5 parts, Ti：7.5 parts, Se：4 parts, S：1 part, P：1 part mixes；
B. gained compound in step A is smelted respectively, blank is formed after hot rolling, and it is thick by being formed after cutting Embryo；
C. the thick embryo obtained to step B is heat-treated, and is machined out to obtain valve semi-finished product；
D. after the valve semi-finished product obtained to step C carry out modifier treatment, polished using emery wheel, deburring, utilize polishing machine Sealing surface is processed by shot blasting, obtains the surface of flat smooth；Modifier treatment in the D steps includes multiple normalized treatment With a temper.The temper gradually heats mode using segmented and heated, and every section is kept for more than 10 minutes Heat duration.
E. painting wear-resistant coating is carried out to the smooth surface of valve obtained by D steps, the wear-resistant coating is tungsten carbide coating.Wear-resisting painting Layer is dried 30 minutes after Puttying, and roller coating surface identification coatings.
Its service life of the valve of gained of the invention is longer, and sealing effectiveness is more preferable.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize invention The equivalent structure or equivalent flow conversion that description is made, or other related technical areas are directly or indirectly used in, It is included within the scope of the present invention.
