Abstract
The invention discloses a method for manufacturing a gas shutoff valve. The method includes steps of 1) extruding aluminum and forming; 2) cutting a blank piece; 3) processing; 4) cleaning; 5) assembling. The gas shutoff valve body is manufactured by extruding aluminum profile, so that the gas shutoff valve body is free of sand holes, the gas shutoff valve assembled by the gas shutoff valve body is good in air tightness and free of gas leak, potential safety hazards are eliminated, and safety is guaranteed. Furthermore, since the gas shutoff valve body is free of the sand holes, repair of the gas shutoff valve due to gas leak is greatly reduced, yield and production efficiency are improved, and social competitiveness of enterprises is enhanced.
Description
Technical field
The present invention relates to gas valve, especially a kind of for making the method for gas valve.
Background technology
At present, in industry, making gas valve main body normally adopts aluminium alloy (ADC-12) to manufacture by the mode of die casting, although it is fast to adopt this kind of mode to produce the speed of gas valve main body, but in the gas valve main body by die casting gained, easily contain trachoma (being husky hole), easily there is gas leak phenomenon in the gas valve that the gas valve main body that adopts die casting is assembled, thereby leave potential safety hazard, gas valve is after assembling completes in addition, need to carry out airtight test, usually cause because of gas leak phenomenon reprocessing, yields is low, therefore reduced widely the production efficiency that enterprise produces gas valve, have a strong impact on the competitiveness of society of enterprise.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide one both simple, can improve again the method for the production efficiency of gas valve.
The present invention is that the technical scheme that its technical problem of solution adopts is:
A method of making gas valve, comprises the following steps:
1), extruded aluminium moulding, by aluminium bar is put in extruder and pushed, obtain being the akin aluminium section bar of cross section of strip and its cross section and gas valve main body;
2), cutting blank, the aluminium section bar obtaining in step 1) is cut, obtain the blank part for making gas valve main body;
3), processing, to step 2) in the blank part that obtains hole, tapping and cutting processing, thereby obtain required gas valve main body;
4), cleaning, adopt the mode of cleaning or blowing or ultrasonic oscillation to carry out debris removal to the gas valve main body obtaining in step 3), clear up residual trifling thing thereon;
5), assembling, by clearing up the complete gas valve main body of trifling thing and other assembling parts in step 4), thereby obtain needed gas valve.
As the improvement of technique scheme, in described step 4), adopt the mode of cleaning to clear up trifling thing residual in gas valve main body.
As the further improvement of technique scheme; while adopting the mode of cleaning to clear up trifling thing residual in gas valve main body in described step 4); first adopt degreaser to carry out oil removing to it; then adopt environmental protection trichloro-ethylene to clean it, finally adopt again sealer to clean its surface and make the surface of gas valve main body form one deck protection oxide-film.
The invention has the beneficial effects as follows: make gas valve main body because the present invention adopts extruded aluminium section, ensure can not contain trachoma in gas valve main body, make to adopt the air-tightness of the gas valve that this gas valve main body is assembled good, gas leak phenomenon can not occur, eliminate safe hidden trouble, ensure safety; In addition, owing to can not containing trachoma in gas valve main body, reduce widely the phenomenon that gas valve need to be reprocessed because of gas leakage, improved yields and production efficiency, thereby strengthened the competitiveness of society of enterprise.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the part drawing of aluminium section bar in the present invention;
Fig. 2 is the part drawing of blank part in the present invention;
Fig. 3 is the part drawing of gas valve main body in the present invention;
Fig. 4 is the part drawing of the gas valve after having assembled in the present invention.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, a kind of method of making gas valve, comprises the following steps:
1), extruded aluminium moulding, first aluminium bar is heated to after hot-forging forming temperature, and then put in extruder and pushed, thereby obtain being the akin aluminium section bar 10 of cross section of strip and its cross section and gas valve main body, in the present invention except adopting the mode of above-mentioned hot extrusion to produce aluminium section bar 10, can also adopt cold-stamped method to produce required aluminium section bar 10, specifically adopt which kind of pressing method freely to select according to actual conditions;
2), cutting blank, utilize cutting machine to cut the aluminium section bar 10 obtaining in step 1), thereby obtain some for making the blank part 11 of gas valve main body, the thickness of described blank part 11 equals or is slightly larger than the thickness of gas valve main body;
3), processing, to step 2) in the blank part 11 that obtains hole, tapping and cutting processing, thereby obtain required gas valve main body 1, and then some corner locations of gas valve main body 1 are carried out to chamfered, make the corner location smooth transition of gas valve main body 1, both improved the quality of gas valve main body 1, can prevent again that the corner location of gas valve main body 1 was because too sharply accidentally injuring staff;
4), cleaning, the gas valve main body 1 obtaining in step 3) is carried out to debris removal, clear up residual trifling thing thereon, in the present invention, the preferential mode of cleaning that adopts is cleared up in gas valve main body 1 residual trifling thing after processing, its process is as follows: first adopt degreaser to carry out oil removing to gas valve main body 1, and then adopt environmental protection trichloro-ethylene to clean it, finally adopt again sealer (oxidant) to clean its surface and make the surface of gas valve main body 1 form one deck protection oxide-film, therefore both made the surperficial noresidue of gas valve main body 1, but also gas valve main body 1 is not easy by air corrosion in follow-up use procedure, extend its service life, in the present invention, except using the method cleaning gas valve main body 1 lip-deep residual trifling beyond the region of objective existence of above-mentioned cleaning, can also adopt the mode of blowing to carry out debris removal to gas valve main body 1, adopt pressure-air to spray the surface of gas valve main body 1, thereby blow off residual its lip-deep trifling thing that is attached to, it is also passable certainly adopting higher-order of oscillation sonic cleaning to be attached to the lip-deep residual trifling thing of gas valve main body 1,
5), assembling, by will in step 4), clear up the complete gas valve main body of trifling thing 1 and other assembling parts, thereby obtain needed gas valve 2.
Finally, by above-mentioned steps 5) in the gas valve 2 that obtains of assembling test, confirm whether it is non-defective unit.
The foregoing is only preferential embodiment of the present invention, as long as within the technical scheme that realizes the object of the invention with basic identical means all belongs to protection scope of the present invention.
