Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1 to Figure 3, admission pressure closing detecting apparatus, including housing 9, microprocessor control module 6, power supply
Module 5 and closed in space 7, closed in space 7 are installed on the side of housing 9, and relay module 2 is installed on opposite side in housing 9, housing
9 inner tops are provided with mounting groove, and vavuum pump 1 is located in mounting groove, vacuum pressure sensor 3, microprocessor control module 6 and power supply
Module 5 is installed on the inner bottom part of housing 9, and display screen 4 is installed on the front end of housing 9, microprocessor control module 6 respectively with display screen 4,
Vacuum pressure sensor 3 and relay module 2 are connected, and relay module 2 is connected with vavuum pump 1, and closed in space 7 passes through pipeline point
It is not connected with vavuum pump 1 and vacuum pressure sensor 3；The interface of closed in space 7 is provided with sealing quick-release connector 8.
For the utility model when making, closed in space 7 is integral forming structure, can use 3D printing rapid shaping；Vacuum
Pump 1 is minipump；Display screen 4 is LCDs, and the lower section of display screen 4 is pressed provided with start button, stop button and reset
Button, start button, stop button and SR, it is connected respectively with microprocessor control module 6.
When in use, the admission pressure that will seal quick-release connector 8 and engineering machinery engine switchs connection to the utility model.
Power module 5 is powered for each part, startup power supply switch, and electricity is automatic to vacuum pressure sensor 3 in microprocessor control module 6
Calibration, presses the start button of minipump 1, and microprocessor control module 6 controls minipump by relay module 2
1 vacuumizes, while microprocessor control module 6 gathers the data of vacuum pressure sensor 3 and is shown to LCDs 4 in real time,
When microprocessor control module 6 detects admission pressure switch alarm, vavuum pump 1 is stopped, global formation closed in space 7
Start slow pressure release, when microprocessor control module 6 detects that admission pressure switch alarm releases, LCDs 4 exports
Current pressure values are shown, the output valve stops display 3 seconds on LCDs 4, so as to complete detection operation.
