Abstract

The invention discloses a vacuum detection device with an on-off function and an on-off method thereof, comprising: a housing, a sliding shell, a stopper, a piston rod, a detector, a connecting rod, and an air intake hole; In the housing, the two outer walls of the sliding housing are closely attached to the two inner walls of the housing. The upper and lower ends of the sliding housing are respectively symmetrically provided with an opening. The number of stoppers is set to two and can be horizontally facing or Sliding on the contrary, the inner surface of the stopper and the inner wall of the sliding housing enclose a detection channel, the detection channel communicates with the opening, the piston rod is hollow inside, and one end of the piston rod vertically passes through the upper end of the housing and is fixedly connected with the upper end of the sliding housing, and The inner cavity of the piston rod is connected with the opening, and the detection end of the tester is connected with the end of the piston rod outside the housing through a hose. Air hole 3 is located at the lower end of the shell and communicates with the inside of the shell.

Description

technical field [0001] The invention relates to the technical field of vacuum detectors, in particular to a vacuum detection device with an on-off function and an on-off method thereof. Background technique [0002] Now the vacuum detector is directly connected to the mechanism that needs to be detected through the pipeline. The internal detection mechanism of the instrument is continuously connected with the detected mechanism. working status. The detection mechanism is prone to aging and failure after long-term use. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a vacuum detection device with an on-off function and an on-off method thereof, which solve the technical problems in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A vacuum detection device with on-off function, comprising: ...
