Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is the metered body constructional drawing;
Fig. 3 is the circuit diagram of numeric display unit.
See also Fig. 1,2.The utility model is a kind of group refueling telltale, comprises numeric display unit 15, microscler urceolus 2, is positioned at the metered body of urceolus 2 bottoms.Wherein:
Urceolus 2 is established oil inlet 1 and oil outlet 4.
Connect the vertical rigid body pipeline 16 that is provided with between the oil inlet 1 of urceolus and the metered body oil inlet.
Metered body is made up of the measurement gear 8 in housing 7 and the housing 7, seal with O RunddichtringO 10 between the end cap of housing and the body of housing, housing 7 tops have the metered body oil inlet, the bottom has metered body oil outlet 9, measurement gear is made of pair of orthogonal assembling, intermeshing elliptic gear, wherein near place, gear major axis two ends two blocks of magnet steel 11 are housed on the gear, the end cap outer wall of housing 7 is magnetoelectric transducer 12 fixedly.Elliptic gear has the advantages that drive torque is little, precision is high, and is more suitable as measurement gear.
The output of magnetoelectric transducer 12 connects the input of numeric display unit 15 through lead 13, and the circuit of numeric display unit 15 is contained in the urceolus 2.
The utility model places in the fuel tank of self-propelled vehicle, and connects with the oil filling port of fuel tank, when covering fuel lid, becomes as a whole with fuel tank.
Narrate its principle of work below:
During oiling, oil gun is inserted the oil inlet 1 of urceolus 2, and overlap 14 epistasis with cone rubber and contact and seal.Fuel oil enters the metered body oil inlet through rigid body pipeline 16, flows out from metered body oil outlet 9 again, and the fuel oil that self-measuring body oil outlet 9 flows out flows into fuel tank through the oil outlet 4 of urceolus 2 again.In this process, measurement gear 8 rotates under the difference of pressure effect of hydraulic fluid port fuel oil in metered body.Because the cavity volume of metered body is certain, gear 8 whenever circles and promptly discharges the fuel oil of certain volume, and gear 8 whenever circles simultaneously, and the magnet steel 11 on it will send two magnetic field impulse signals, thereby the fuel oil that adds certain volume to fuel tank is promptly represented in each pulse.This impulse singla converts electric pulse to by magnetoelectric transducer 12, is calculated by numeric display unit 15 then, and shows the actual amount of fuel of the metered body of flowing through.
For simplified structure, can adopt the no touch inductosyn to obtain the rotation number of turns of measurement gear, this class sensor comprises magneto-electric, photo-electric etc.Even if magnetoelectric sensor also can have polytype selective, the magnetoelectric transducer 12 in the present embodiment is to have adopted simple and practical Hall device.
The top that present embodiment is arranged on urceolus with the oil outlet 4 of urceolus 2 is higher than the position of metered body.Measurement gear is immersed in the oil all the time, thereby improves measuring accuracy.
In other embodiment of the present utility model, in order to improve measuring accuracy, filter screen 5 can be set in pipeline 16, enter metered body to prevent foreign material; Or connect a freeing pipe 3 that is communicated with pipeline 16 on pipeline 16 tops, discharging oiling residual gas in the metered body when beginning, and avoid the air admission metered body in the fuel oil.
In addition, but in urceolus 2 charge of oil position indicating device 6, this device can adopt simple float-float bowl structure.In refueling process, when being added to when a certain amount of, float raises with the pasta in the fuel tank and floats, and when float floats to the top, shows that fuel tank fills it up with, can stop to refuel.
Above-mentioned numeric display unit 15 can be made of the circuit with shaping, counting, Presentation Function.In an embodiment of the present utility model, this device is made up of micro controller system, dresser, memory device, nixie display, button, see also Fig. 3, the input of dresser Q1 connects the output of magnetoelectric transducer 12 through Connector Clip J1, the output of dresser Q1 meets the data input pin P3.5 of micro controller system U1 (optional 89 series monolithics of model), memory device U2 meets data port P1.3, P3.4, P3.7, the P1.2 of micro controller system, nixie display meets the data output P1.4-P1.7 of micro controller system U1, and button S1 and S2 meet data input pin P3.2, the P3.3 of micro controller system U1.Nixie display and button are installed in is convenient to the place of observing and operating.
The electric pulse that magnetoelectric transducer 12 is sent here is after Q1 amplifies shaping, and U1 adds up this pulse and calculates by the computing formula of storing among the U2, and result of calculation send nixie display to show.One button is used for the telltale zero clearing, and another button can be used for selecting to show the accumulative total volume read-out or do standby.
Consider the security requirement of petrol service station, produce electric Mars for preventing button in make and break process, button can adopt dry-reed tube to constitute.
Because this circuit powered battery, so also be connected to the low voltage monitoring circuit at P1.2, P3.1, the P1.0 end of micro controller system U1.
The utlity model has following advantage:
1. because the contactless inductosyn of employing obtains the rotation number of turns of measurement gear, so the machinery knot Structure is simple, cost is low;
2. owing to adopt elliptic gear to make measurement gear, its driving moment is little, flows out so relatively be fit to fuel oil The littler situation of pressure behind the nozzle;
Since measurement gear wheel be immersed in the oil all the time, thereby can improve measuring accuracy.
