In our lives, atmospheric pressure is ubiquitous, and although not sensed by people, the atmospheric pressure is very strong, the pressure of the atmospheric pressure acting on an object with the square meter is equivalent to 10 tons of weight, and if the pressure is used for doing work, huge productivity is generated. The premise of utilizing the atmospheric pressure is to generate vacuum, and after the vacuum is generated, the atmospheric pressure can apply pressure to the vacuum direction. The atmospheric pressure acts on the surface of the object to form a certain pressure, and the atmospheric pressure value is fixed and unchanged, so the size of the formed pressure is in direct proportion to the acting area. When the acting pressure is fixed, the acting area directly determines the acting effect, and the generated pressure is inversely proportional to the acting area.

And observing the pressure gauge 12 in the air exhaust process, stopping air exhaust when the pressure gauge 12 displays that the data is the test pressure, and closing the stop valve f16, so that the air tightness test can be performed on the pipeline.
Since the ratio of the upper and lower end areas of the force transmission element B5 is greater than the ratio of the upper and lower end areas of the force transmission element a2, the pipe system will be subjected to a greater test pressure when the stop valve f16 is closed and the stop valve h21 is opened to evacuate the cavity B.
