Problems solved by technology
[0003] At present, the existing test method is to block the inlet and outlet of the valve with a blind plate, and then carry out vacuum leak detection. When testing different working conditions, it is necessary to change different tooling and test methods. The test operation is complicated, and the requirements for testers are high. Quantitative valve testing, so it is urgent to design a vacuum valve test tool to solve these problems

The invention discloses a testing tool for a vacuum valve, and the testing tool comprises a rectangular installation bottom frame, a rectangular steel casting box, test valves, a control valve group and a control cabinet; the rectangular steel casting box is fixedly installed at one side of the top of the rectangular installation bottom frame through a first welding frame and a second welding frame, and the test valves are fixedly installed in the centers of the two sides of the rectangular steel casting box; and the control valve group is fixedly installed at the position, close to the rectangular steel casting box, of the top of the rectangular installation bottom frame. When the tool is in use, the test valve is directly mounted on the rectangular hole; then the SV008 vacuum pump is controlled by the control cabinet to vacuumize the interior of the rectangular steel casting box; in the vacuumizing process of the rectangular steel casting box, the pressure bearing capacity of the test valve is accurately detected according to the air pressure, detected by the JC-1000 air pressure sensor, in the rectangular steel casting box, the control test process is simplified and standardized, and therefore, no excessive operation requirement is needed for workers.
Description
technical field [0001] The invention relates to the technical field of vacuum valve testing, in particular to a testing tool for vacuum valves. Background technique [0002] Vacuum valves refer to vacuum system components used to change the direction of air flow, adjust the size of air flow, and cut off or connect pipelines in a vacuum system. The closing parts of vacuum valves are sealed with rubber seals or metal seals. In terms of field, some large vacuum valves need to be used, and these valves need to be tested under pressure during production. [0003] At present, the existing test method is to block the inlet and outlet of the valve with a blind plate, and then carry out vacuum leak detection. When testing different working conditions, it is necessary to change different tooling and test methods. The test operation is complicated, and the requirements for testers are high. Quantitative valve testing, so it is urgent to design a vacuum valve testing tool to solve thes...
