Description
technical fieldthe utility model belongs to flowmeter technology field, is specifically related to a kind of heavy caliber ultrasonic flowmeter transducer seat.
background technologyat present, the ultrasonic calorimeter that central heating industry household metering adopts, its principle utilizes a transducer to launch ultrasound wave in medium (water), and by another receive MUT, a difference can be produced compared with normal speed because ultrasound wave flows together along medium (water) stream, when the medium (water) in ultrasonic wave propagation path flows, this channel ultrasound velocity of wave propagation can with water (flow) direction, water velocity generation respective change, using the pipeline of fixing bore as ultrasonic wave propagation path, the flow velocity of the medium (water) of pipeline is so just calculated by ultrasound wave time difference measurement, according to the bore of measuring tube, medium temperature, Media density calculates certain hour interior conduit medium volumetric flow rate and mass rate.Ultrasonic flow meter is installed on heating system water supply or water return pipeline, pairing temperature sensor is arranged on system water supply, return pipe respectively, the pulse signal that counter is directly proportional to flow by flowmeter collection, by the simulating signal of pairing temperature sensor acquisition tables temperature indicating difference, integrating formula is finally utilized to calculate the heat of heat-exchange system release.
Existing transducer field engineering arranges a jack respectively at the two ends of base table housing, transducer level is inserted, employing level installs the mode of correlation, although this structure is simple, but the numerical value measured is a part for base table housing entirety flow tangent plane, there is the technical matters that measuring error is large, and around table body, circuit is chaotic, maintenance difficulty, uses inconvenience.
summary of the inventionthe purpose of this utility model solves prior art to there is the technical matters that measuring error is large, use inconvenience, provides a kind of heavy caliber ultrasonic flowmeter transducer seat.
A kind of heavy caliber ultrasonic flowmeter transducer of the utility model seat, it comprises transducer, its main points are that described transducer is arranged in the groove of hollow holders bottom, the wire connecting transducer is drawn from the upper end of hollow holders through hollow holders by the through hole on groove, transducer pressing plate is provided with above described transducer, the periphery of transducer pressing plate is provided with fixing threaded hole, and the centre of transducer pressing plate is provided with size, center pit that shape is corresponding to transducer; O-ring seal is provided with between described transducer and transducer pressing plate.
During use, be arranged on by two the utility model transducer holder Relative vertical in the oblique relative jack in heavy caliber base table of ultrasonic flow meter two ends, stationary gland on it, wire is drawn by the through wires hole on gland.
The utility model adopts at right angle setting correlation mode, and measurement range contains whole base table inner gateway, and it is more accurate to measure, and parts, circuit arrange in good order, efficiently solve prior art measuring error large, use inconvenient technical matters.

embodimentsee figures.1.and.2, a kind of heavy caliber ultrasonic flowmeter transducer of the utility model seat, it comprises transducer 8, its main points are that described transducer 8 is arranged in the groove of hollow holders 7 bottom, the wire 3 connecting transducer 8 is drawn from the upper end of hollow holders through hollow holders by the through hole on groove, transducer pressing plate 10 is provided with above described transducer 8, the periphery of transducer pressing plate 10 is provided with fixing threaded hole, and the centre of transducer pressing plate 10 is provided with size, center pit that shape is corresponding to transducer 8; O-ring seal 11 is provided with between described transducer 8 and transducer pressing plate 10.
During installation, with reference to Fig. 3 and Fig. 4, transducer is arranged in hollow holders 7, then put O-ring seal, be fixed with transducer pressing plate 10, hollow holders is inserted in the jack 1 of base table housing 4, wire 3 is passed through through wires hole 5 below gland 2, by bolt 6, gland 2 is fixed; During inspection, be connected by wire carry out data on flows test with computer main board, experimental data is accurate, can put use on market.
Also there is following advantage in the utility model:
1, adopt flowmeter transducer erecting device newly developed, transducer assembly technology is optimized further, transducer convenient for assembly, and production efficiency improves further, and assembly quality is guaranteed;
2, the transducer holder assembly technology of flow tube and employing new construction is convenient, and one time assembly yield is high;
3, after adopting Novel structure, flow measurement pipe processing technique is more simple, convenient, and working (machining) efficiency, yields and machining precision promote further, effectively raise the measuring accuracy of the whole table of heavy caliber flowing meter
4, be convenient to dismounting, later maintenance is simple, reduce maintenance cost.
