Abstract
The invention discloses a manufacturing method of a corrosion-resistant metal valve. The valve has the beneficial effects of being resistant to corrosion, low in cost, high in thermal fatigue performance, high in heat stability and excellent in comprehensive performance. A high-temperature-resistant and oxidation-resistant ceramic coating is formed on the inner surface of the valve so that the inner surface of the valve can have the higher surface oxidation resistance, meanwhile the outer surface is plated with copper, and the metal valve looks more magnificent and high-graded.
Description
Technical field
The present invention relates to a kind of manufacturing process of valve, particularly a kind of manufacture method of corrosion resistant metal valve.
Background technology
Valve is generally made up of the valve internals of valve body and valve inner, can be divided into metal valve, Plastic valve and ceramic valve according to manufactured materials.
In production technology and technique, comparatively ripe in family expenses valve is metal valve, market comparatively common are stainless valve and copper valve, also cast iron valve is had in the product of low side a little, but there is considerable defect in existing metal valve, metal valve is in life-time service process, extremely easily there is the problems such as burn into gets rusty, plating exfoliation, can penetrate in domestic water gradually for the manufacture of heavy metals such as the lead in the alloy of metal valve, tin, domestic water is polluted, directly affects the healthy of people.
Summary of the invention
For solving the problem, the invention discloses a kind of manufacture method of metal valve.
In order to achieve the above object, the invention provides following technical scheme: a kind of manufacture method of corrosion resistant metal valve, the material of described manufacture metal valve comprises as follows:
(1) metallic substance is carried out melting;
(2) undertaken building base substrate by the material feeding mould after above-mentioned melting;
(3) base substrate of building is cooled 10-20 hour as in sand;
(4) the metal valve base substrate of building is carried out anneal;
(5) again metal valve base substrate is carried out quench treatment;
(6) the metal valve base substrate after tempered process is carried out insulation 2-4 hour, be cooled to 200-250 DEG C to come out of the stove;
(7) emery wheel is adopted to refine metal die base substrate, surface working is smooth.
(8) ethanolic soln of putting into of metal valve base substrate carries out immersion 15-20min;
(9) metal valve base substrate is done as carrying out spray in nitrogen;
(10) be target with SiC, pass into rare gas element, the internal surface of metal valve base substrate is sputtered, be sputtered onto the thickness of coating of 100-200nm;
(11) copper plating treatment is carried out at the outside surface of metal valve base substrate.
Beneficial effect:
Metal valve of the present invention by manufacturing process, has corrosion resistance nature, with low cost, thermal fatigue property, thermostability are high and the feature of high comprehensive performance.By forming high temperature resistant, an oxidation resistant ceramic coating at the internal surface of valve, make the internal surface of this valve have higher surface oxidation-resistant ability, surperficial plated with copper seems that more air improves grade outside simultaneously.
