The invention provides a cylinder valve airtightness testing machine. The cylinder valve airtightness testing machine comprises a cylinder valve test bed, a control cabinet, an air compressor and an air storage tank; an air outlet of the air compressor is connected with an air inlet of the control cabinet and the air storage tank through metal pressure-bearing pipelines; an air inlet of the cylinder valve test bed is connected with an air outlet of the control cabinet through a metal pressure-bearing pipeline; an air storage tank pressure gauge and an electromagnetic valve are arranged on an air path between the air compressor and the air storage tank; and the control cabinet is in circuit connection with the air compressor, the cylinder valve test bed, the air storage tank pressure gaugeand the electromagnetic valve. By means of the cylinder valve airtightness testing machine provided by the technical schemes of the invention, the air storage tank and the electromagnetic valve are arranged in air tightness test equipment, so that an air path connected with the control cabinet, the cylinder valve test bed and the air storage tank is closed by the electromagnetic valve during a pressure boosting test, and meanwhile, the air path of the control cabinet, the cylinder valve test bed and air compressor is opened, so that pressure boosting can be ensured; and during a pressure maintaining test, the gas path connected with the control cabinet, the cylinder valve test bench and the air compressor is closed, and the gas path connected with the control cabinet, the cylinder valve test bench and the air storage tank is opened, so that pressure maintaining in an airtight test is ensured.
Description
technical field [0001] The invention relates to the technical field of airtight testing equipment, in particular to a bottle valve airtight testing machine. Background technique [0002] At present, the airtightness test has not done the pressure-holding test. According to the national standard GB12137, the airtightness test not only has the pressure requirement, but also has the pressure-holding requirement, so the pressure of the air source system is required to be stable. An air storage tank is installed between the machines to ensure a stable supply of pressure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bottle valve airtight test machine, which solves the problem of pressure-holding test in the airtight test. [0004] In order to solve the above technical problems, the present invention provides a bottle valve airtight testing machine, which includes a bottle valve test bench, a control cabinet, an a...
