Background
In the existing air cannon valve body product, even if the rapid discharge valve acts under the condition that the air pressure in the valve body is less than 0.1Mpa, the opening pressure difference of the nozzle piston is formed instantly, but the opening pressure of the nozzle piston cannot overcome the pressure of the spring, so that the air cannon cannot work under the condition of small pressure. Meanwhile, the requirements that working conditions such as small-spray violent soot blowing are only needed, and steam with accurate quantitative volume needs to be supplemented to the hydrolysis furnace are met. The traditional air cannon cannot meet the requirements. The quantitative micro-pressure air cannon valve body developed by the company can well solve the problem, and the micro-pressure air cannon valve body can normally work under any pressure of 0-0.3Mpa, so that the blank of related aspects in China is filled.
