In protection set 13 inner chambers.As it is shown in figure 1, when air filtering plug operates with pipe joint 14 grafting, described protection set 13 pressure
Contracting resilient sleeve 12 and relative to pipe joint 14 to left movement, until air filtering plug puts in place with pipe joint 14 grafting, rotate
Air filtering plug, makes air filtering plug be stuck in pipe joint 14；Then, described protection set 13 is by the elasticity in resilient sleeve 12
Reset under power effect.
Put in place to better assure that air filtering plug is installed, improve the reliability of pressure sensing result further, such as Fig. 1
Shown in, motion chamber 32 and photoswitch groove can be set inside pedestal 3, arrange at motion chamber 32 opening and fix with pedestal 3
The fixed block 11 connected, arranges photoswitch 8 in photoswitch groove；Preferably, lead between described fixed block 11 and pedestal 3
Cross attachment screw 16 to form a fixed connection.It is installed with circuit board 7 at pedestal 3 top, described circuit board 7 fixedly mounts
Pressure transducer 5 and photoswitch 8, described pressure transducer 5, photoswitch 8 form with circuit board 7 respectively and electrically connect, as
Shown in Fig. 2.Therefore, described photoswitch 8 is connected in motion chamber 32 and with defining between pedestal 3 to fix.Described
Pipe joint 14 is fixedly connected on one end of lead 9, and the other end of described lead 9 is then fixing with pedestal 3 to be connected, preferably
Ground, forms screw thread movable connection structure, to facilitate the dismounting of lead 9 to grasp between the other end and the pedestal 3 of described lead 9
Make.Described resilient sleeve 12 is fixing with motion block 10 to be connected, and described motion block 10 is positioned in motion chamber 32 and is formed sliding with lead 9
Dynamic socket join structure, described lead 9 offers fluid passage, makes to be formed between pipe joint 14, lead 9, atmospheric pressure cavity 31
One gas channel.Wherein, described protection set 13, motion block 10, fixed block 11 are made up of nylon66 fiber, described resilient sleeve
12 are made up of neoprene, not only process, assemble easily, and implementation cost is cheap.
As it is shown on figure 3, described pressure transducer 5 is sequentially connected electrically with A/D converter, control device, display device, institute
Electrically connect with photoswitch 8 while of stating the input controlling device, and outfan electrically connects with alarm device simultaneously.Described control
Device processed uses single-chip microcomputer or PLC, and described display device can use LCDs, or uses LED charactron,
It is mainly used for showing pipeline detected pressure value.Described alarm device can use buzzer, or uses alarm lamp.
When air filtering plug inserts pipe joint 14, described resilient sleeve 12 and motion block 10 are slided to the left along lead 9
Dynamic, and move closer to atmospheric pressure cavity 31.In order to improve resilient sleeve 12, the sliding stability of motion block 10, with ensure air filtering plug with
Smooth grafting between pipe joint 14, can fix on fixed block 11 and connect the guide post 15 being parallel to each other with lead 9,
And formation is slidably socketed structure, as shown in Figure 1 between guide post 15 and motion block 10.Described motion block 10 in sliding process, its
Can finally rest in photoswitch groove through photoswitch groove, detect whether this motion block 10 rests on light by photoswitch 8
In electric switch groove, send corresponding alarm signal according to alarm device, can judge that air filtering plug is the most exactly
Grafting puts in place.After air filtering plug grafting puts in place, the air pressure in pipeline to be measured can be detected by pressure transducer 5
Signal, this pressure signal is transferred to control device after A/D converter processes, and is demonstrated the pressure detected by display device
Force value；The alarm signal sent according to alarm device, it may be determined that whether this force value detected is within normal range.
