Fig. 1 is the structural schematic diagram of the utility model.

Label in attached drawing are as follows: 1, insulation water pipe, 2, electrode, 3, fixed plate, 4, semicircular iron core, 5, magnet exciting coil, 6, Control cabinet, 7, display screen, 8, indicator light, 9, support, 10, angle steel.

Specific embodiment

The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific implementation described herein Example is only used to explain the utility model, is not used to limit the utility model.

In the description of the present invention, it should be understood that term " side ", " other side ", " two sides ", " between ", The orientation or positional relationship of the instructions such as " middle part ", " upper end ", " lower end " is to be based on the orientation or positional relationship shown in the drawings, and is only For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is set Set ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can It, can also be indirectly connected through an intermediary to be to be connected directly.It for the ordinary skill in the art, can be specific Situation understands the concrete meaning of above-mentioned term in the present invention.

As shown in Figure 1 be a kind of steel-making feedwater flow measuring device, there is insulation water pipe 1, edge on 1 wall of insulation water pipe Central axes are symmetrical arranged electrode 2, and electrode 2 is embedded to be fixed in insulation water pipe 1, are horizontally disposed on the outer wall of insulation water pipe 1 solid Fixed board 3, the outer ring that the top and bottom of fixed plate 3 are located at insulation water pipe 1 are respectively provided with semicircular iron core 4, in semicircular iron core 4 Equal winding magnet exciting coil 5 at 2 position of portion's comparative electrode, 5 one end of magnet exciting coil pass through conducting wire with 2 one end of electrode and connect control cabinet 6。

Wherein, display screen 7 is set on control cabinet 6 and indicator light 8, indicator light 8 is fixed at 7 lower end of display screen.Electrode 2 Section is trapezoidal, and insulation water pipe 1 separates the insulation of electrode 2 in embedded setting insulation water pipe 1.The both ends of semicircular iron core 4 It is fixed in fixed plate 3 by support 9.Fixed plate 3 is fixedly connected with insulation water pipe 1 by angle steel 10.

The steel-making is as follows with the operating principle of feedwater flow measuring device:

The liquid of electric conductivity cutting magnetic line in flowing, can also generate induced electromotive force.Therefore electromagnetic induction can be applied Law measures flow velocity, and electromagnetic flow transducer is exactly according to made of this principle.Excitation voltage is passed in magnet exciting coil 5 Afterwards, insulation water pipe 1 is just in the uniform magnetic field that density of line of magnetic force is B, when the conductive liquid that mean flow rate is v flows through insulation When water pipe 1, then the electricity as represented by following formula will be generated in a pair of electrodes 2 being arranged on the duct wall that conducting wire internal diameter is D The volume flow of kinetic potential e, i.e. liquid flowing:

The mean flow rate (m/s) of v in formula --- liquid；The magnetic flux density (T) in B --- magnetic field；The internal diameter of D --- conduit (m)。

The steel-making of the application has with existing feedwater flow measuring device following excellent relatively with feedwater flow measuring device Point: one, there is no mechanical movable part.Two, due to the internal diameter that the distance of electrode is just conduit, without interfering fluid flowing Obstacle, the pressure loss is minimum.Three, the output signal directly proportional to volume flow can be obtained.Four, measurement result is not by fluid The influence of viscosity.Five, it since electromotive force is to measure in the section part of the conduit comprising electrode as mean flow rate, is flowed Speed distribution influences smaller.Six, measurement range is wide, can be from 0.005 --- 190000m3/h.Seven, measurement accuracy is high, reachable ± 0.5%.

It is above-described, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is simultaneously It is not limited to this, anyone skilled in the art within the technical scope disclosed by the utility model, according to this reality It is subject to equivalent substitution or change with novel technical solution and its utility model design, should all covers the protection in the utility model Within the scope of.
