Referring to Fig. 1, a kind of dredger of the small-bore pressure measurement pilot hose of the parallel multiplex of the embodiment of the present invention is led
Pressing hose includes the first pilot hose 10 and the second pilot hose 50, and one end of the first pilot hose 10 is provided with pressure sensing hole 20,
The other end of first pilot hose 10 is connect with the second pilot hose 50, and the other end of the second pilot hose 50 connects an acquisition
Device 60；Dredger includes a triple valve 30, and the first pilot hose 10 and the second pilot hose 50 pass through 30 phase of triple valve
Connection, the third interface of triple valve 30 connect a dredging pipeline 70, and the other end connection one of the dredging pipeline 70 is micro- just
Pressure generating apparatus 80 is dredged on pipeline 70 and is additionally provided with a check valve 90, a valve is provided on the first pilot hose 10
40。
Above-mentioned dredger, by the way that triple valve 30 is arranged between the first pilot hose 10 and the second pilot hose 50,
The one dredging pipeline 70 of another interface connection of triple valve 30, the other end of the dredging pipeline 70 connect a micro-positive pressure generating device
80, and valve 40 is set on the first pilot hose 10；When blocking in the second pilot hose 50, collector 60 is collected
Pressure signal obviously weaken, at this time close valve 40, make dredge pipeline 70 be connected to the second pilot hose 50 formation it is relatively close
The environment of envelope opens micro-positive pressure generating device 80 and generates air pressure, can dredge to the second pilot hose 50；By dredging
Check valve 90 is set on pipeline 70, is avoided when device for pressure measurement works, air-flow enters dredging pipe from the first pilot hose 10
Road 70 and the normal work for influencing device for pressure measurement.The dredger structure is simple, can send out in the second pilot hose 50
The second pilot hose 50 is effectively dredged when raw blocking.
In the present embodiment, the first pilot hose 10 should be arranged shorter as far as possible, in this way, being unlikely to lead to sand and dust, powder
The molecules such as dirt or haze block in the first pilot hose 10.
In order to realize that the purge operation to the second pilot hose 50 carries out automatically controlling, referring to Fig. 1, in the present embodiment,
Dredger further includes a controller 100, valve 40, collector 60 and micro-positive pressure generating device 80 with the controller 100
Connection.When blocking in the second pilot hose 50, the pressure signal that collector 60 acquires obviously weakens, at this time by controller
100 control valves 40 are closed, and control the unlatching of micro-positive pressure generating device 80, are generated air pressure and are dredged to the second pilot hose 50
It is logical, realize the automatic control to the purge operation of the second pilot hose 50.
Further, in the present embodiment, controller 100 is also connected with a timing module (not shown).Pass through
The interval time dredged to the second pilot hose 50 is arranged in the timing module, is when the dredging time for reaching setting, by controlling
Device 100 processed controls micro-positive pressure generating device 80 and dredges to the second pilot hose 50.So set, realizing to the second pilot
The regular automatic removing obstruction of hose 50, reduces the maintenance times of device for pressure measurement, extends maintenance period.
Referring to Fig. 1, in the present embodiment, the first pilot hose 10, the second pilot hose 50 and dredging pipeline 70 are more
Root, every first pilot hose 10 are connected by a triple valve 30 and a second pilot hose 50 and a dredging pipeline 70
It connects, the other end of more second pilot hoses 50 is connect with collector 60 respectively, and the other end of more dredging pipelines 70 passes through one
A multiway valve 110 is connect with micro-positive pressure generating device 80 respectively, is provided with a check valve 90 on every dredging pipeline 70,
