Portable sealed negative pressure detection device

Abstract

The invention provides a portable sealing negative pressure detection device, and relates to the technical field of sealing detection. The portable sealing negative pressure detection device comprises a glass curtain wall, a shell, a detection device, an air supply device, a driving motor, a heat supply mechanism, a fixing mechanism and a negative pressure disc. The shell is arranged on the two sides of a glass curtain cavity, the detection device is fixedly connected to the bottom end of the middle of the shell, and the air supply device is fixedly connected to the position, close to the upper end, in the shell. The driving motor is fixedly connected to the position, close to the bottom end, in the shell, the heat supply mechanism is fixedly connected to the side, away from the glass curtain wall, in the shell, and the fixing mechanism is fixedly connected to the side, close to the glass curtain wall, of the two ends of the shell to fix the shell. The negative pressure disc is fixedly connected to the middle in the shell. The invention provides the portable sealing negative pressure detection device, and solves the problem that the air tightness detection result of the glass curtain wall is affected by wet air after raining and water vapor on the surface of glass.

Description

technical field [0001] The invention relates to the technical field of seal detection, in particular to a portable seal negative pressure detection device. Background technique [0002] Sealing test, as the name implies, refers to testing the airtightness of the sample and whether it leaks. It has a wide range of applications and is suitable for packaging bags, boxes, bottles, The tightness testing of cans, etc. can also be tested for products that have their own sealing requirements. [0003] Glass curtain walls are widely used in modern buildings, but the air tightness of the glass curtain walls needs to be tested before they are put into use, but if it is rainy weather, a layer of water vapor will be formed on the surface of the glass curtain walls The air in the air is relatively humid. If the air tightness test of the glass curtain wall is carried out at this time, the test result will be interfered by the humid air and the water vapor on the glass surface, thus affect...
