The sampling end of primary element extends to the different zones in flue, while being provided with the port of its sampling end described from deashing
Device, the output end of primary element connects the entrance of the magnetic valve, and the outlet of magnetic valve connects the main pipe, and main pipe passes through institute
The transmitter that pressure guiding pipe is connected in switch board is stated, while entering by cable between control module in magnetic valve and switch board
Row electrical connection.
Further, into some regions, the monitoring point of every group of primary element is respectively positioned in region the flue mesh generation
The heart.
Further, the primary element uses the pipe of high-quality wear-and corrosion-resistant stainless steel.
Further, the quantity of the primary element is three, and every is provided with three monitoring points above.
Further, the switch board uses high-quality stainless steel, and inside is provided with transmitter and solenoid valve control mould
Block, to magnetic valve independent control, realizes the collection of pressure signal subregion and is converted into the output of 4-20mA current signals by transmitter.
The beneficial effects of the utility model are：The utility model is changed and cannot realize in the past zoning monitoring, measurement representative
Property it is poor, easily block, the problems such as captured area is big.The system realizes the measurement of flue flow field subregion, multizone or region-wide same
When measurement etc. function；Primary element uses high-quality wear-and corrosion-resistant stainless steel tube, while being respectively provided with from clearly in primary element porch
Apparatus for ash, has the advantages that wear-resistant, long service life, certainty of measurement are high.

Road.
Specific embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of multiphase flow medium velocity zoning monitoring system, it is included from deashing device 1, primary element
2nd, magnetic valve 3, main pipe 4, pressure guiding pipe 5 and switch board 6, the quantity of the primary element 2 are at least two, primary element 2
Sampling end extends to the different zones in flue 7, while being provided with the port of its sampling end described from deashing device 1, one
The output end of item 2 connects the entrance of the magnetic valve 3, and the outlet of magnetic valve 3 connects the main pipe 4, and main pipe 4 is by described
Pressure guiding pipe 5 is connected to the transmitter in switch board 6, while passing through cable between control module in magnetic valve 5 and switch board 6
It is electrically connected.
Such as Fig. 2, shown in Fig. 3, the mesh generation of the flue 7 is into some regions, every group of primary element of primary element this case
Monitoring point i.e. equivalent to sampling monitoring bar is respectively positioned on regional center.Wherein, primary element uses stainless pipe form, right
Being dammed for flue can ignore substantially.Preferably, the quantity of primary element 2 is three, and every is provided with three monitoring points above.
In summary, some primary elements are set according to flue zoning, and flue is realized by electromagnetism Vavle switching
The measurement of flow field subregion, multizone or region-wide while measurement.Flue is divided into multizone, multigroup primary element is set, often
Group primary element pressure tap is located at regional center point, representative strong；Every group of primary element pressure tap position is equipped with from deashing dress
Put, effectively solve blockage problem.Wherein from the underslung port installed in sampling end of deashing device 1.Specially：In entrance
The hole of 5mm is opened on the side wall at end, with the stainless steel iron wire of 4mm through two through holes opened on pipe fitting and from deashing device 1
Deashing rod on suspension annulus hole, weld 4 steel wires and polish smooth, need to ensure that steel wire can freely swing, and can not have bright
Aobvious bending.When media impingement deashing rod, deashing rod can freely swing along axle center, collide overhang region, play from deashing function.
