| titleOfInvention | Canister gas tightness on-line measuring device |
| abstract | The invention provides an online gas tightness detection device for a canister, which comprises a processing platform, four supporting legs vertically connected with the lower end of the processing platform and a bearing base fixedly connected with the upper end of the processing platform, wherein a bulge is arranged at the upper end of the bearing base, the upper end of the bulge is inserted into an inner cavity of a canister body through an outlet of the canister body, a gas supplementing control device is arranged above the canister body, and the upper end of the gas supplementing control device is connected with the output end of a hydraulic cylinder. The invention overcomes the defects of the prior art, has reasonable design and compact structure, fills compressed air by sealing the inlet and the outlet of the canister, keeps the canister body to reach a certain pressure for 1 minute, and counts the air filling amount in unit time by the air mass flow, namely the air leakage amount in unit time, thereby effectively solving the problems of simple structure, uncontrollable flow, single test condition and inconvenient monitoring of the test process of the air tightness test. |
