Description

Technical Field

[0002] A fire extinguisher, also known as a fire extinguisher, is a portable fire-fighting tool. Fire extinguishers contain chemicals that are used to put out fires. Fire extinguishers are one of the most common fire prevention facilities and are stored in public places or places where fires may occur. Because of their simple and portable design, ordinary people can also use them to put out small fires that have just occurred. Different types of fire extinguishers contain different ingredients and are designed for different fires. In the prior art, it is well known that the fire extinguisher tank is mostly made of steel plates. First, the steel plate is rolled into a cylindrical shape, and then the upper head and the lower head are installed at both ends. Then the tank is welded to make the upper head and the lower head tightly combined with the tank body. However, in the entire production process, there may be cold welding, false extrusion, excessive extrusion, etc., and the fire extinguisher tank will leak. Therefore, it is very important to perform air tightness detection on the fire extinguisher tank. However, there is no professional automatic detection equipment at present. It is all done manually by injecting high-pressure gas into the produced storage tank and then putting it into water to see if there are bubbles generated at the joint of the storage tank to judge the air tightness of the storage tank.
