[specific embodiment]
It is described in further detail with embodiments of the present invention below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of box body tightness detection device includes housing 1, the shell
Be provided with controller 2 in body 1, the controller 2 be connected with for set casing initial pressure value admission pressure setting device 3,
Admission pressure is reached for the pressure sensor 4 of atmospheric pressure value in detection case body, for detecting casing air pressure in pressure sensor 4
The first magnetic valve 5 of air inlet gas circuit is turned off during 3 setting value of setting device, rear box Sealing period is turned off for setting air inlet gas circuit
With input keyboard 6, the timer 7 for calculating the box sealing time, the use that Sealing period terminates barometric minimum numerical value in casing
Box body tightness is pointed out when the casing atmospheric pressure value of the detection of pressure sensor after terminating in Sealing period 4 is higher than barometric minimum numerical value
The qualifying warning light 8 of qualifying, the second magnetic valve 9 for opening air pressure in outlet gas circuit discharge casing, also set in the housing 1
There is the first three-way connection 10, the connection end of first three-way connection 10 first is connected with casing, first three-way connection 10
Two connection ends are connected with pressure sensor 4, and the connection end of the first three-way connection 10 the 3rd is connected with the second three-way connection 11, institute
State the connection end of the second three-way connection 11 second to be connected with the second magnetic valve 9, the connection end of second three-way connection 11 the 3rd and the
One magnetic valve 5 is connected, and first magnetic valve 5 is connected with admission pressure setting device 3, the admission pressure setting device 3 connects
It is connected to the water treatment plant 12 for filtered compressed gas moisture.
Wherein, the controller 2 is connected with the casing atmospheric pressure value for the detection of pressure sensor 4 after Sealing period terminates
