Via hole entrance 31 and sealing surface are uniformly arranged along 30 circumferencial direction of spool.
When initially use, operator can make the smallest via hole entrance 31 of diameter and via hole with rotational valve core 30
32 connection of outlet, and sense that the gas flow in bye-pass 22 that pressure sensor 220 detects becomes in control device
When change, control signal is sent to driving mechanism, driving mechanism drives spool 30 to rotate, so that the via hole entrance 31 that diameter is bigger
It is connected to conducting hole exits 32, to increase from the gas flow for attracting terminal by flow control valve 3 into bye-pass 22.
Pressure sensor 220 is annular, and the inner wall of bye-pass 22 is provided with annular groove, annular pressure sensor
220 are fixedly installed in annular groove.It is annular that pressure sensor 220, which is arranged, can be from 22 circumference all directions of bye-pass
The pressure in bye-pass 22 is sensed, so that the pressure value detected is more accurate.Pressure sensor 220 precisely, real-time monitoring
Pressure in bye-pass 22 passes through control when occurring blocking in bye-pass 22 causes gas unsmooth flowing logical or other exceptions
The opening degree of device flow automatic regulation regulating valve 3, adjusting gas flow, so that gas flows unimpeded, bye-pass 22
Interior pressure recovery is stablized.
Negative-pressure suction pipeline 2 with preventing clogging up device further includes having warning device, and warning device connects control device, control
Device processed can preset standard pressure value, when pressure value in the bye-pass 22 received is greater than reference pressure value, control report
Alarm device alarm.When there is Severe blockage in bye-pass 22, the pressure that pressure sensor 220 detects persistently enhances, so that
Pressure value in bye-pass 22 is greater than the reference pressure value of setting, i.e., so that the gas flow in bye-pass 22 is less than gas flow
When standard value, control device, which can control, at this time closes flow control valve 3, and medical worker's processing is reminded in warning device alarm.Report
Alarm device can be buzzer or the red light of flashing.
As shown in figure 4, the negative-pressure suction pipeline 2 with preventing clogging up device is made of the first pipeline and the second pipeline, first
It is tightly connected between pipeline and the second pipeline using threaded end (TE), for connecting branch pipeline 21, the second pipeline is used for the first pipeline
Connection attracts terminal；Pressure sensor 220 is set in the first pipeline；Flow control valve 3 is set in the second pipeline, the second pipe
Be additionally provided with filter device 4 in road, filter device 4 be located at the second pipeline and the first pipeline connecting pin and flow control valve 3 it
Between, for the second pipeline of filtration, purification from attract terminal extract gas.Entered in bye-pass 22 by 4 Duis of filter device of setting
Gas be filtered purification so that phlegm, blood, purulence and other internal dirts are blocked in the second pipeline before filter device 4,
When pressure sensor 220 senses that the pressure in bye-pass 22 changes, i.e., discovery bye-pass 22 blocks, it can
Guarantee that blocking occurs before the filter device 4 of the second pipeline, it, can be by the second pipe when maintenance personal clears up blocking
Road and the first pipeline disassemble, it is only necessary to clean to the second pipeline, greatly reduce the maintenance difficulty of maintenance personal；
