Abstract

The invention provides an on-line detection device for gas tightness of a canister. The on-line detection device comprises a processing platform, four supporting feet which are vertically connected toa lower end of the processing platform, and a bearing base which is fixedly connected to an upper end of the processing platform; an upper end of the bearing base is provided with a bump; an upper end of the bump is inserted into the inner cavity of a canister body through the outlet of the canister body; a gas supplement control device is arranged above the canister body; and an upper end of thegas supplement control device is connected with an output end of a hydraulic cylinder. The on-line detection device overcomes the defects in the prior art, and has the advantages of reasonable designand compact structure. By enclosing the inlet and outlet of the canister and filling compressed air, the canister body is kept under a certain pressure for one minute. By counting the gas supplementamount within unit time, namely, gas leakage amount within unit time through air mass flow, the problems of simple structure, uncontrollable flow, single testing condition and inconvenient monitoringof testing process in gas tightness testing are solved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to an on-line air tightness detection device for a canister. Background technique [0002] The canister is a device that removes dust and toxic and harmful substances in the air through physical adsorption and chemical reaction for human breathing. Usually canisters are used in conjunction with gas masks. Canisters are very important epidemic prevention and protective articles in social life, especially when catastrophes such as earthquakes, floods, and infectious diseases (such as SARS) are prevalent, it is very important. Since the canister is usually used in conjunction with the gas mask, the quality of the canister mainly depends on its filtering and adsorption functions, which requires that the airtightness of the canister must be kept good, so the airtightness of the canister Detection is even more important. [0003] In the existing air tightness testing of can...
