The specific embodiment
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Such as Fig. 1 in conjunction with Fig. 3, shown in Figure 4, this can be located direct-reading type double-flow water quantity adjusting device and comprise halter assembly 1, upper flow meter 2, regulates Control Component 3, host component 4, magnetic orientation assembly 5, positioning and guiding assembly 6 and down-off meter 7, positioning and guiding assembly 6 upper ends are fixed with positioning sleeve 13, guide way shell 14, positioning sleeve 13 lower ends place on the boss of guide way shell 14 inner chambers, and 6 of described host component 4 and positioning and guiding assemblies are fixedly connected with magnetic orientation assembly 5; As shown in Figure 2, described magnetic orientation assembly 5 shells are main body tube 8, main body tube 8 is built-in with circuit board support 9, Hall element a 10, coil block 16, Hall element b15, coil rack 11 and magnetic orientation support 12, and main body tube 8 lower ends are against positioning sleeve 13 upper ends; Described magnetic orientation support 12 tops are cylindrical cavity, axially have the duct in the magnetic orientation support 12 bottom entities; Magnetic orientation support 12 upper end nailed circuit timberings 9 are fixed with circuit board 17 on the circuit board support 9, circuit board support 9 upper ends are connected with the shell body of host component 4; Coil block 16 is wrapped on the I-shaped wire ring framework 11; Hall element a10, coil rack 11, Hall element b15 are installed in the magnetic orientation support 12 top cylindrical cavities successively, and Hall element a 10 and Hall element b15 place respectively coil rack 11 two ends; Described circuit board support 9, coil rack 11 axial centre have through hole, in the duct, magnetic orientation support 12 bottom, in circuit board support 9 and coil rack 11 through holes and Hall element a 10, Hall element b15 outside be installed with electric wire, the lower end of electric wire is passed positioning and guiding assembly 6 and is connected with down-off meter 7, and the upper end of electric wire connects host component 4.
Circuit board on the described circuit board support 9 is provided with single-chip microcomputer, field effect transistor switch pipe, constant-current source, linear Hall integrated circuit.This circuit can be realized two byte datas (content is sampling interval internal magnetic field strength test value) are returned geoceiver, issues with orders such as pressure, temperature, flows during tie-in, and ground is surveyed and transferred software to show in real time the magnetic orientation curve.Board circuit schematic diagram on the circuit board support 9 as shown in Figure 6, schematic block circuit diagram is as shown in Figure 5.Wherein single-chip microcomputer is opened field effect transistor switch pipe N1 for generation of control signal, and with inner integrated digital to analog converter the output signal of linear Hall integrated circuit D2 is sampled; Field effect transistor switch pipe N1 is used for converting the low tension switch signal of single-chip microcomputer the high pressure positive pulse signal of 51V to drive late-class circuit; Constant-current source circuit N2 is used for the rear class load current is constant in 70mA, thereby guarantees that the magnetic field intensity that the rear class coil produces in full temperature scope under the same external condition is constant; High temperature coil X1, the number of turn is constant in the full temperature scope, and the electric current that passes through is also constant, then its magnetic field that externally produces in the constant situation of condition is also constant, when external condition changed, it produced immediately with varying magnetic field, thereby can identify wall thickness and the internal diameter varies situation of down-hole string; Linear Hall integrated circuit D2 can quick and precisely measure magnetic field intensity and convert the DC simulation signal to and carry the ADC sampling for the sheet of rear class single-chip microcomputer.
