Problems solved by technology

[0002] At present, the main body of the gas valve in the industry is usually made of aluminum alloy (ADC-12) through die-casting. Although the speed of producing the main body of the gas valve in this way is fast, the main body of the gas valve obtained by die-casting is likely to contain trachoma ( That is, sand holes), so that the gas valve assembled with the die-casting gas valve body is prone to air leakage, which leaves a safety hazard. In addition, the gas valve needs to be tested for air tightness after the assembly is completed. As a result, repairs are required and the yield rate is low, which greatly reduces the production efficiency of the company's gas valve production and seriously affects the social competitiveness of the company.

Embodiment Construction

[0019] refer to figure 1 Referring to Fig. 4, a method for making a gas valve includes the following steps:

[0020] 1) Extruded aluminum forming, first heat the aluminum rod to the hot forging temperature, and then put it into the extrusion machine for extrusion, so as to obtain a strip shape and its cross section is the same as the cross section of the gas valve body Similar to the aluminum profile 10, in the present invention, in addition to the above-mentioned hot extrusion method to produce the aluminum profile 10, the cold extrusion method can also be used to produce the required aluminum profile 10, which extrusion method can be used according to free choice according to the actual situation;

[0021] 2) Cutting the blank, using a cutting machine to cut the aluminum profile 10 obtained in step 1), so as to obtain several blanks 11 for making the main body of the gas valve, the thickness of the blank 11 is equal to or slightly greater than the thickness of the gas valv...

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 [0001] The invention relates to a gas valve, in particular to a method for making a gas valve. Background technique [0002] At present, the main body of the gas valve in the industry is usually made of aluminum alloy (ADC-12) through die-casting. Although the speed of producing the main body of the gas valve in this way is fast, the main body of the gas valve obtained by die-casting is likely to contain trachoma ( That is, sand holes), so that the gas valve assembled with the die-casting gas valve body is prone to air leakage, which leaves a safety hazard. In addition, the gas valve needs to be tested for air tightness after the assembly is completed. This leads to the need for repairs and low yield, which greatly reduces the production efficiency of the gas valves produced by the company and seriously affects the social competitiveness of the company. Contents of the invention [0003] In order to solve the above problems, the object of the present inven...
