Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.Certainly, specific embodiment described herein is only explaining this practicality
It is new, it is not used to limit the utility model.
Embodiment 1
Referring to Fig. 1 to Fig. 4, a kind of detector for tightness, including base 1, vacuum chamber 2 is set on base 1, set in base 1
Put vavuum pump, exhaust tube and the inside UNICOM of vacuum chamber 2 of vavuum pump；
The air path part that vavuum pump is connected with vacuum chamber 2 sets sensor, sensor connection control system.Sensor is gas
Pressure sensor, its model SZ19.
The gas circuit of the present apparatus is made up of muffler, vavuum pump, magnetic valve one, four-way, the vacuum chamber being sequentially connected, four-way
Other both ends set sensor respectively, and form pressure release path by magnetic valve two and atmosphere.
Control system uses MEGA128 single-chip microcomputers, using ATmega64L microcontrollers as main control chip；Pass through RS232 interface
As output end.
Top cover 21 is set at the top of vacuum chamber, and reserved through hole on top cover 21, through hole sets negative port, and the rear side of base 1 is pre-
The through hole that the exhaust tube 3 for vavuum pump passes is stayed, exhaust tube 3 passes through negative port and the inside UNICOM of vacuum chamber 2.
The upside of top cover 21 sets handle, and downside is fixedly connected with pressing plate 23 by the support plate 22 being vertically arranged, and pressing plate 23 is horizontal
Set, be distributed through hole thereon.
Vacuum chamber 2 is transparent tank body.
The rear side of base 1 sets pressure regulator valve 4, RS232 interface and the pressure release mouth of pipe 6, power interface 7；The front side of base 1 be provided with
