Abstract

This creation is related to a gas spray gun, which is mainly assembled with a connecting tube at the front end of the main body of the spray gun, and a mixing tube is arranged at the front end of the connecting tube, and the connecting tube and the mixing tube are each provided with several through holes. A shunt block is provided at the front end of the air mixing pipe, whereby when the gas enters the air mixing pipe from the spray gun body through the connecting pipe, the outside air will enter the pipe through the through holes provided in the connecting pipe and the air mixing pipe and mix with the gas. The gas mixed with air is output to the outside after being diverted and pressurized at the front end of the mixing pipe. According to this, after the gas is ignited, the flame can be burned outside the mixing pipe and avoid burning the mixing pipe. In addition, the gas is mixed with air several times when it passes through the connecting pipe and the mixing pipe, so as to effectively improve the gas combustion efficiency and achieve the required temperature for work.

Description

Gas spray gun

This creation is about a gas spray gun, especially a gas spray gun that can fully mix gas with air to improve combustion efficiency and increase the gas output flow rate to ensure that the flame can burn outside the mixing tube after the gas is ignited.

Therefore, when in use, the gas switch is used to adjust the flow of gas into the spray gun. When the gas switch is tightened, the gas cannot enter the spray gun. As the gas switch is turned on, the flow of gas into the spray gun gradually increases. Therefore, to control the strength and closure of the flame. However, because the existing gas spray gun only has a few through holes on the gas mixing pipe, the amount of air entering the gas mixing pipe is limited, so that the mixing efficiency of gas and air is not good, resulting in incomplete gas combustion, and the flame temperature is also difficult to reach the required value. Requires working temperature conditions. Furthermore, because the gas output flow rate of the existing gas spray gun is slow, it is easy to produce flames in the gas mixing tube when ignited, which will cause burning phenomenon to the gas mixing tube. In addition to causing damage to the gas mixing tube, it is also easy to cause the heating of the gas mixing tube to increase. There is a danger of scalding from the mixing tube during use.

The reason is that, in view of the above-mentioned shortcomings in the use of existing gas spray guns, the creator used his many years of manufacturing and design experience and knowledge in related fields to assist, and through many ingenuities, he developed this creation.

This creation is about a gas spray gun. Its main purpose is to provide a gas spray gun that can fully mix gas and air to improve combustion efficiency and increase gas output flow rate to ensure that the flame can burn outside the mixing tube after gas is ignited Gas spray gun.
