Abstract
The invention discloses a leakage-proof valve production process. The leakage-proof valve production process is characterized in that a sealing layer made of rubber and adopting the same structure as a valve body is placed into a die for casting production of the valve body, a heat insulating layer is arranged on the outer surface of the sealing layer, then a liquid metal is injected into the die, the die is closed after completion of injection, the unformed valve body is pressed to remove inside air, the surface of the cooled and formed valve body is polished to be smooth and galvanized, the thickness of the sealing layer is one fourth of that of the valve body, electrogalvanizing can be selected, the outer surface of the heat insulating layer adopts a concave-convex structure, the liquid metal is a stainless steel material, and the sealing layer is made of elastic rubber. The rubber sealing layer is cast into the valve body to play the leakage-proof role and can prevent liquid or gas from leakage when the valve body is broken, and the leakage-proof valve production process is simple to operate and convenient for production.
Description
Technical field
The present invention relates to a kind of production technology, especially a kind of valve body production technology for preventing from seeping water, leaking and burst.
Background technology
The valve body of conventional valves is all adopt metal material; durable durable at people's metal material, but due to produce quality and technological problems, usually there will be oozing of valve body in life and split phenomenon; so just there is potential safety hazard, after there is situation, also can waste resource.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, provides a kind of valve body production technology that can effectively prevent from valve body from oozing splitting.
The technical solution used in the present invention is: a kind of valve body production technology preventing seepage, it is characterized in that, the sealant of the quality of rubber materials identical with valve body structure is placed in the mould that valve body is produced in casting, the outer surface of described sealant arranges thermal insulation layer, then liquid metals is injected mould, after injection, mould is closed, the pressurization of unfashioned valve body is extruded to the air of the inside, after cooling forming, valve body surface is polished level and smooth and zinc-plated.
Aforesaid a kind of valve body production technology preventing seepage, is characterized in that: the thickness of described sealant is 1/4th of valve body thickness.
Aforesaid a kind of valve body production technology preventing seepage, is characterized in that: zinc-platedly adopt electrogalvanizing.
Aforesaid a kind of valve body production technology preventing seepage, is characterized in that: the outer surface of described thermal insulation layer arranges concaveconvex structure.
Aforesaid a kind of valve body production technology preventing seepage, is characterized in that: described liquid metals is stainless steel.
Aforesaid a kind of valve body production technology preventing seepage, is characterized in that: described sealant adopts the rubber with retractility.
By technique scheme, the invention has the beneficial effects as follows: the present invention casts among valve body by being watered by rubber sealant to play the effect preventing seepage, when the valve body rubber sealant that breaks also can prevent the leakage of liquid or gas, and the present invention is simple to operate, is convenient to produce.
Detailed description of the invention
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with preferred embodiment, to its detailed description of the invention proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
A kind of valve body production technology preventing seepage, the sealant of the quality of rubber materials identical with valve body structure is placed in the mould that valve body is produced in casting, the outer surface of described sealant arranges thermal insulation layer, then liquid metals is injected mould, after injection, mould is closed, unfashioned valve body pressurization is extruded to the air of the inside, after cooling forming, valve body surface is polished level and smooth and zinc-plated, the thickness of described sealant is 1/4th of valve body thickness, zinc-platedly adopt electrogalvanizing, the outer surface of described thermal insulation layer arranges concaveconvex structure, described liquid metals is stainless steel, described sealant adopts the rubber with retractility.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
