Description

Technical Field

[0001] The present application relates to the field of gas valves, in particular to metal gas valves for automobile die-casting and spraying equipment. Background Art

[0002] The air valve is installed inside the paint spraying device and is used to control the gas connection of the paint spraying tool. It is often used in the die-casting spraying equipment of automobiles. When the current air valve is in use, one end of the connecting tube is connected to the gas, and an adjusting rod is installed on the inner wall of the connecting tube with the help of a limit spring. The adjusting rod blocks the inner wall of the connecting tube with the help of the limit spring to block the incoming gas. When the paint spraying tool is in use, the air valve is moved by pushing the adjusting rod to allow the gas to pass through.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when a conventional air valve is used, since the spraying direction is fixed, the spraying range is likely to be relatively concentrated after the paint is sprayed out, resulting in excessively thick spraying in some areas, thus affecting the spraying effect of the spraying equipment.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
