Abstract

The invention relates to a flammable and explosive gas verification fume hood which comprises a hood body, a closed hood door and an exhaust structure, the closed hood door comprises a fixed plate, a sliding plate with an operation hole and a telescopic sleeve, the fixed plate is fixedly connected with the hood body and arranged in the hood body, the sliding plate is in sliding fit with the fixed plate and arranged on the lower side of the fixed plate, and the telescopic sleeve is arranged on the lower side of the fixed plate. The telescopic sleeve is embedded in the inner side of the operation hole and fixedly connected with the inner wall of the operation hole, the telescopic sleeve and the sliding plate are additionally arranged on the basis of an existing ventilation cabinet, through cooperation of the telescopic sleeve and the sliding plate, the ventilation cabinet can be closed when a user operates the ventilation cabinet or does not operate the ventilation cabinet, and when flammable and explosive gas is operated, the ventilation cabinet can be closed through the telescopic sleeve and the sliding plate. And through the arrangement of a fixed plate and a sliding plate, direct injury of explosion to a user is avoided, and the safety performance of the ventilation cabinet is effectively improved.

Description

technical field [0001] The invention relates to a flammable and explosive gas testing fume hood. Background technique [0002] As a kind of equipment that is often used in chemical laboratory tests, the fume hood protects the personal safety of operators by eliminating the toxic and harmful gases generated during the test and verification process. In order to improve the safety performance of the fume hood in the prior art, a pull-up type is usually used to improve the airtightness of the fume hood. However, in the actual use process, it is found that when the fume hood needs to be operated inside, the door of the fume hood needs to be opened, which has the risk of harmful gas leakage. Once some flammable and explosive gases leak, Threat to the life of the user. Contents of the invention [0003] The purpose of the present invention is to provide a flammable and explosive gas testing fume hood to solve the problem of insufficient protection of flammable and explosive gas...
