It is tested to experience the air pressure change of tested inside air bag, be located at the acquisition of baroceptor 3 in detection air bag 4 by induction end again
The air pressure change data of inside air bag, therefore the application eliminates during carrying out air pressure detection to tested air bag tested
The valves such as guide pipeline and triple valve are connected on air bag, are detected also without connecting the valves such as guide pipeline and triple valve on air bag 4,
It is only provided with the conducting wire 6 for connecting baroceptor 3 with external microcontroller, therefore on air pressure measuring apparatus (i.e. connected piece) not
The tracheae slot of milling complexity again also removes excessive, complicated, interminable line arrangement from, finally mitigates air pressure measuring apparatus significantly
The difficulty of Machine Design and mechanical processing.Meanwhile modularization air pressure testing agency uses modularized design, it is whole by mounting base 1
Body installation or removal are in pressure test device, and installation and replacement all facilitate and effectively save installation space；In addition, modularization gas
Press testing agency's overall structure simple, at low cost.
As shown in Figure 1, modularization air pressure testing agency further includes the breather check valve being sealingly mounted in sealed connecting component 2
5, one end of the breather check valve 5 is communicated in the inside of detection air bag 4, the other end with atmospheric pressure, therefore breather check valve 5 is connected to
Inside and the atmospheric pressure of air bag 4 are detected, breather check valve 5 makes 4 air inlets of detection air bag, holds one's breath, therefore breather check valve 5 ensures
Detection air bag 4 can restore after deforming to original state, while also ensure that detection air bag 4 is air tight in air pressure detection process, carries
Hyperbar accuracy of detection and accuracy.
As shown in Figure 4 and Figure 5, the preferred mounting structure of the baroceptor 3 and breather check valve 5 is：The sealing
Connector 2 is a cylindrical parts, its main body is cylindrical, offers in sealed connecting component 2 and is mutually fitted with the shape of baroceptor 3
The sensor installation cavity 21 and valve installation cavity 22 compatible with the shape of breather check valve 5 matched, can save space；Institute
It is two mutually independent chambers, all along the axially extending of sealed connecting component 2, institute to state sensor installation cavity 21 and valve installation cavity 22
It states baroceptor 3 to be sealingly mounted in sensor installation cavity 21, the breather check valve 5 is mounted in valve installation cavity 22, can
The lateral interference generated when mounted to avoid baroceptor 3 and breather check valve 5.In addition, the sealed connecting component 2 is passing
At one end of the sensor installation cavity 21 far from detection air bag 4 offers first through hole 25, and the first through hole 25 is along sealed connecting component 2
Conducting wire 6 axially through sealed connecting component 2, for drawing connection baroceptor 3 and microcontroller；The sealed connecting component 2 exists
At one end of the valve installation cavity 22 far from detection air bag 4 offers the second through-hole 26, axis of second through-hole 26 along sealed connecting component 2
To perforation sealed connecting component 2, for making breather check valve 5 be connected to atmospheric pressure.The aperture of the first through hole 25 is less than sensor
The internal diameter of installation cavity 21, the aperture of second through-hole 26 is less than the internal diameter of valve installation cavity 22, therefore sealed connecting component 2 is in sensor
The junction of installation cavity 21 and first through hole 25 and all it is formed with installation in the junction of valve installation cavity 22 and the second through-hole 26
Step.Preferably, between the baroceptor 3 and sensor installation cavity 21 and breather check valve 5 and valve installation cavity 22 it
Between all connected by epoxy glue seal, realize epoxy formula sealing, this sealing means more stablize, sealing it is also relatively reliable.Separately
Outside, in the application, the baroceptor 3 preferably uses absolute pressure formula baroceptor, stability preferable.
As shown in Figures 2 and 3, the preferred structure of the detection air bag 4 is：The detection air bag 4 includes in hemispherical
The air bag interconnecting piece 43 and be connected to airbag body portion 42 and air bag that airbag body portion 42 and sealed connecting component 2 are tightly connected
The peripheral surface in the air bag plane portion 44 between interconnecting piece 43, the airbag body portion 42 constitutes the compression face 41, the air bag
Body part 42 can be 1/2 ball or 3/4 ball, and the air bag interconnecting piece 43 is along the axially extending of sealed connecting component 2, the air bag

The contact area that tested air bag acts on detection air bag 4 can be increased, and vertically apply pressure to convenient for tested air bag and detect air bag 4
Compression face 41, therefore during tested air bag pressure detects, when detection 4 stress of air bag squeezes, the deflection of detection air bag 4 has
Effect increases, and keeps the air pressure change inside detection air bag 4 more obvious, direct, thus data acquisition is just more accurate, so that
The barometric surveying of tested air bag is more accurate.
Preferred Hermetical connecting structure between detection air bag 4 and the sealed connecting component 2 of above structure is：Such as Fig. 1 to Fig. 6 institutes
Show, the periphery of the sealed connecting component 2 towards one end of detection air bag 4 is set there are two barb 24, the barb 24 it is outer
Diameter is gradually increased along the direction that air bag interconnecting piece 43 is sleeved on sealed connecting component 2, therefore the peripheral surface of barb 24 is circular conical surface, and
The outer diameter of barb 24 is slightly larger than the internal diameter of air bag interconnecting piece 43, thus air bag interconnecting piece 43 be sleeved on the periphery of sealed connecting component 2 after,
Air bag interconnecting piece 43 is interference fit with barb 24 so that air bag interconnecting piece 43 is interference fitted with sealed connecting component 2, is effectively carried
Connection reliability between high air bag interconnecting piece 43 and sealed connecting component 2.Particularly, in order to further ensure air bag interconnecting piece 43
Mounting base 1 is clamped in air bag interconnecting piece 43 and is tightly connected by the reliability being tightly connected between sealed connecting component 2, the application
The periphery of part 2, the coupling part for compressing air bag interconnecting piece 43 and sealed connecting component 2 effectively ensure that detecting air bag 4 does not leak
Gas, therefore mounting base 1 plays the role of installation and clamping simultaneously.Specifically, the mounting base 1 includes two symmetrically arranged clampings
Part 11 and the tightening component for connecting two tightenings of clamping element 11, two clampings of clamping elements 11 are connected to air bag interconnecting piece 43
With the periphery of sealed connecting component 2, therefore clamping through-hole 14 is offered on each clamping element 11.The tightening component preferred structure
For：The tightening component includes tensioning screw and the tightening hole 12 that is opened in each clamping element 11, the tensioning screw with receive
Tieholen 12 is threadedly coupled, behind the periphery for the coupling part that two clamping elements 11 are sleeved on air bag interconnecting piece 43 and sealed connecting component 2,
Tensioning screw is tightened, until two clamping elements 11 are tightened, therefore the tightening of two clamping elements 11 is simple to operate.
