The utility model is characterized in that the utility model also comprises a flow measuring sensor, a display circuit and a control circuit which are connected with the output of an infrared receiving circuit, etc., wherein, the flow measuring sensor is composed of an infrared emitting circuit, an infrared receiving circuit, and the float which is arranged in the conical tube to shield infrared light; an emitting tube and a receiving tube which are arranged in the infrared emitting circuit and the infrared receiving circuit are respectively arranged on both sides of the outer part of the conical tube. The utility model has the advantages of simple structure, low cost, high precision, high stability, wide application range, convenient operation, etc.
Description
The utility model flowmeter belongs to fluid flow metering technical field, specifically a kind of infrared spinner-type flowmeter of measuring liquid or gas flow.
At present domesticly be used for metallurgy, machinery, oil field, brew alcoholic beverages, medicine, chemical industry, chemical fibre, chemical fertilizer and departments such as scientific research and environmental protection, measure the instrument of liquid, gas instantaneous delivery, generally the flowmeter of Shi Yonging is by in vertical Taper Pipe, the float that can move up and down is housed forms.The flow that records is looked into by artificial sight, and not only effort is used inconvenience, and limited measuring accuracy widely.
The purpose of this utility model provides a kind of infrared emission, receives the spinner-type flowmeter of electronics from motion tracking, demonstration flow, and this flowmeter is a core with infrared emission, the electronic light-controlled circuit of reception, reaches purpose convenient, the high-acruracy survey flow.
The purpose of this utility model is achieved in that it includes Taper Pipe, float, top base flange and bottom base flange, it is characterized in that also comprising by infrared emission circuit and infrared receiving circuit and be arranged on the float that blocks infrared emission light in the Taper Pipe of being with light hole and constitute flow measuring sensor, and the display circuit, the control circuit that link to each other with the infrared receiving circuit output terminal, wherein power valve in infrared emission circuit and the infrared receiving circuit and receiving tube are separately positioned on the outer both sides of Taper Pipe.The light-operated tracking circuit of infrared exoelectron and spinner-type flowmeter two parts.The core is made up of infrared exoelectron emission, reception light-operated circuit.Its principle is: in vertical cone pipe, the float that can move up and down is housed, when fluid is flowed through Taper Pipe from bottom to top, by the float throttling, produces differential pressure between the float upstream and downstream.Float rises under this differential pressure effect.During the equating with joint efforts of gravity, buoyancy and the viscous force three that the power that rises when float and float are suffered, float is in the equilibrium position, therefore the flow through fluid flow of flowmeter and the lifting height of float, that is and the circulation area of flowmeter between exist certain proportionate relationship.For the corresponding different flow value of the differing heights of different medium floats.By the floating position of infrared light control circuit tracing float in Taper Pipe, the conversion output voltage signal, connect secondary instrument and can record and show fluid instantaneous delivery and integrated flow value, the distinctive feature of the infrared light control circuit that is adopted in addition also is and can controls liquid, gas flow automatically by secondary instrument.
The advance of the utility model flowmeter is to adopt the electronic auto-control system, is the function of fluid flow and the function of controlling liquid, gas flow thereby make spinner-type flowmeter have from the motion tracking float position.This is the key problem in technology of spinner-type flowmeter.Also be to have adopted the metal material Taper Pipe, solved for a long time the not technical barrier of energy measurement high temperature, high-pressure fluid flow of spinner-type flowmeter.
Below in conjunction with accompanying drawing the utility model flowmeter is described in further detail:
Fig. 1 is the structural representation of the utility model flowmeter
Fig. 2 is the circuit theory diagrams of the utility model flowmeter
By shown in Figure 1, the utility model flowmeter includes top base flange 1, bottom base flange 5, measures flow Taper Pipe 8, and the Taper Pipe 8 of measuring flow is made for metal material or plastics or glass tube.The metal Taper Pipe has high temperature resistant and high voltage bearing performance.The plastics Taper Pipe has overcome the shortcoming of glass conical tube cracky, is provided with to be used for indicator solution, gas flow and to block infrared first float 3 in Taper Pipe 8, the outside surface of metal material float is added have anticorrosion, wear-resistant nickel phosphorus layer or equadag coating.Also comprise by infrared emission circuit and infrared receiving circuit (shown in Figure 2) in addition and be arranged on the flow measuring sensor that the float that blocks infrared light in the pipe constitutes, and the secondary instrument (summary) that links to each other with the infrared receiving circuit output terminal, wherein power valve 2 in infrared emission circuit and the infrared receiving circuit and infrared receiving tube 7, be separately positioned on the both sides of Taper Pipe 8, in also being respectively arranged with, the both sides of Taper Pipe 8 adorn the aluminium alloy shielding box 10 of infrared emission circuit and infrared receiving circuit in addition, the infrared passing through plate 6 that has the deep hole passage is arranged between two shielding boxs 10 and the Taper Pipe 8, and infrared transmitting tube and infrared receiving tube are installed in the deep hole passage of infrared separately passing through plate 6.According to use needs also be equipped with at the rear portion of housing can clear observation flow daylight lamp, 4 among Fig. 1 is the infrared emission circuit board in addition, 9 is the infrared receiving circuit plate.By schematic diagram 2 as can be seen: F1, F2-Fn are the real work circuit of infrared transmitting tube; J1, J2 to Jn are the infrared receiving circuit that infrared receiving tube and resistance, electric capacity and transistor are formed; P1, P2 to Pn are the output terminal of infrared receiving circuit, are connected with diode in series D1 to Dn respectively.The emitter output circuit that the anode of D1 connects a current-limiting resistance and is made up of fortune amplifier OP and transistor T, output terminal OUT connects secondary instrument.
