Detailed Description
In order to make the technical features and advantages or technical effects of the technical scheme of the utility model more obvious and understandable, the following detailed description is given with reference to the accompanying drawings.
The utility model discloses an air tightness detection device, which is shown in fig. 1, and comprises a switch 1, a gas filter element 2, a pressure gauge 3, a hose 4 and a container 5, wherein the specific structure and the function of each part are as follows.
The container 5 holds water for detection and is used for holding equipment 6 to be detected. The device 6 to be inspected needs to be almost completely immersed in the inspection water. The volume of the container 5 may be selected according to the size of the apparatus 6 to be detected, and the present utility model is not limited.
The front end of the hose 4 is used for being connected with compressed air, the tail end is used for being connected with equipment 6 to be detected, and air tightness detection is carried out by inputting the compressed air into the equipment 6 to be detected. The type and model of the hose 4 can be selected as desired, and the present utility model is not limited.
The switch 1 is arranged on the hose 4 and is used for controlling the on-off of air in the hose 4. The type and model of the switch 1 can be selected as required, and the present utility model is not limited.
