Description
Technical field
This Shi structure of Xin Xing Wataru and a kind of electromagnetic flow transducer is improved, and Qi Wataru of You and a kind of electromagnetic flow transducer of measurement cavity without liner being applicable to heat metering belong to electromagnetic-type electronic water meter technical field.
Background technology
From on February 18th, 2000 Ministry of Construction issued " 76 command " formally start centered by heat metering supply hot water reform since, governments at all levels give unprecedented attention to heat metering reform.Firmly the portion of building also clearly represents: within 2012, will deepen heat metering reform, and heat supply energy consumption statistic information platform is set up in research.Strengthen heat billing supervision and check dynamics, push forward household measurement heat-supplying fee collection comprehensively.And as the terminal user of household heat supplying metering, what the common people were concerned about most is exactly that hope heat can as use water, and electricity consumption is the same, can objective reasonably according to consumption reality number pay the fees.Calorimeter flows through the flow sensor of the heat transport fluid flow of heat exchanger primarily of one in order to measure, a pair respectively in order to measure heat transport fluid at the water inlet of heat exchanger and leaving water temperature temperature sensor, and a heat energy intelligence arithmetical unit is formed.Then the heat transport fluid flow provided according to coupled flowmeter and temperature sensor by heat energy arithmetical unit and Inlet and outlet water temperature data, go out by calculation of thermodynamics formulae discovery the heat that user's heat-exchange system obtains or absorb.Can say, the performance of a calorimeter, function and quality depend primarily on the Performance and quality of the flow sensor detecting heat transport fluid flow.But the quality of current National calorimeter product is very pessimistic, can the calorimeter ratio of 3 years ' operation less than 10%, the flow sensor of the direct contact heat transport fluid of the calorimeter phenotype institute Bian come into the market is described, is not too suitable for domestic existing central heating fluid water quality.
Electromagnetic flow transducer, as the measuring instrument of tracer liquid flow, has the premium properties of many uniquenesses, is particularly suitable for domestic existing central heating fluid water quality.But conventional electromagnetic flow sensor Bian stainless steel pipe, insulation liner body (rubber) is needed at stainless steel pipe tube wall, and the electrode base etc. that will freeze, the technique of processing and manufacturing is comparatively loaded down with trivial details, the said goods is made to be difficult to production line balance assembling and scale of mass production, causing expensive production cost thus, limiting the product for civilian use technical field that high performance electromagnetic flow transducer has a large capacity and a wide range at some, as done the application in heat metering instrument field.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, with low cost, processing technology is easy, be convenient to the electromagnetic flow transducer of measurement cavity without liner of assembly operation, and the electromagnetic flow transducer of this function admirable be incorporated in the manufacturing technology of the electromagnetic-type electronic water meter of heat metering instrument--calorimeter and water utilities trade settlement.
For achieving the above object, the technical scheme that Bian gets is: measure the electromagnetic flow transducer of cavity without liner, comprise one measure cavity, be arranged on a pair potential electrode of described measurement cavity inner wall, the field coil of the outer both sides relatively of the described measurement cavity that is placed in, it is characterized in that: described measurement cavity Bian is without the metal tube of liner; Described measurement cavity inner wall is equipped with the insulating base for embedding potential electrode, and described potential electrode is fixedly connected with described insulating base is embedded; Described field coil adopts E shape folded silicon steel slice iron core with the iron core pole shoe integral structure of yoke.
Described measurement cavity is non-magnetic metal tube, in venturi tubulose, or in straight pipe shape.
Described potential electrode is made by non-magnetic metal material, and adopt the job operation of injection mo(u)lding, potential electrode be embedded in insulating base, described potential electrode and the injection mo(u)lding of described insulating electrode pedestal embed and be connected and fixed.
Described a pair field coil, is the iron core pole shoe and the yoke that are become the integration of E type by the punching silicon-steel that magnetoconductivity is higher, is then inserted in field coil the excitation system forming sensor.
The beneficial effects of the utility model are: (1) electromagnetic flow transducer because of Bian measures cavity need not liner new technology, structure simplifies greatly, the processing and fabricating that hot investment casting is once-forming, low cost of manufacture, simple and convenient assembly; (2) embedded one-body molded insulation measurement electrode, substantially increases reliability and the Grade such as sealing of potential electrode sealing; (3) iron core pole shoe and the yoke of the integration of E type is become by the punching silicon-steel that magnetoconductivity is higher, then the excitation system structure formed in field coil is loaded, overcome the shortcoming compared with wide arc gap and less surface of contact between independent iron core pole shoe and yoke, not only increase space magnetic field intensity, also ensure that in best electromagnetic induction space uniform magnetic field characteristic, decrease excitation power consumption simultaneously, thus under identical flow velocity, improve the conversion ratio of flow signal to induction electromotive force e.
