Abstract
The utility model relates to a special pipe section of transducer to measure the liquid flow or heat in a pipe by ultrasonic testing technology, which is suitable for measuring liquid flow or heat in small caliber, particularly suitable for household micro power consumption ultrasonic flow rate or heat meter. The technique proposal is that: the utility model comprises a pipe section inlet (1), a pipe section outlet (2), a sensor (3), a sensor (4) and a line segment (5); the inner liquid path in the pipe section changes direction by rotation of 90 degrees with the same direction of rotation and a straight path, that is line segment (5), is formed in the pipe section between two direction change. The sensor takes little room in the pipe section which can ensure the liquid flow rate. The liquid flow rate is stable and the signal fluctuation is small in Pi-shaped pipe section, which improves the measurement precision. If scale phenomenon appears on the sensor after some time, the sensor can be taken out conveniently from left or right end of the pipe section to clean, which solves the problem of difficult cleaning after sensor scaling. The utility model has reasonable structure, enlarged flow rate of liquid, improved measurement precision and is convenient to clean etc, which overcomes the shortcoming in existing technology.
Description
Affiliated technical field:
The utility model belongs to acoustics, field of sensing technologies, particularly utilizes ultrasonic detecting technology, and the special-purpose pipeline section of the transducer of fluid flow or heat is applicable to the metering of fluid flow, heat in the little caliber in the metering pipeline.Be specially adapted to residents, little power consumption ultrasonic flow rate, calorimeter.
Background technology:
At present, domestic existing pipeline ultrasonic flow rate, calorimetric transducer, it is measured the used pipeline section of passage and generally is made of pipeline section wall, sensor mounting hole, the sensor mounting hole is arranged on the pipeline section wall, with pipeline section endoporus UNICOM, the pipeline section structure mostly is straight length, for example, the applicant's Chinese patent " ultrasonic flow rate, the special-purpose pipeline section of calorimeter transducer ", patent No. ZL03239079.3.In use there is following problem in this pipeline: at first, sensor that this kind structure transducer is used and assembly thereof take too much space in the pipeline section, have limited the flow of liquid, can't satisfy the traffic requirement of regulation; Secondly, liquid is subjected to more obstruction when flowing in pipeline section, and the fluidised form fluctuation is bigger, and ultrasound wave needs the reflecting surface in the pipeline section repeatedly to reflect, and energy loss is bigger, directly influences measuring accuracy, and is particularly evident to the precision influence of little caliber; In addition, inner sensor is not quick detachable, and scale problems is difficult to solve.
The utility model content:
The utility model purpose provides a kind of ultrasonic flow rate, calorimeter transducer π type pipeline section, increase space and fluid flow in the pipeline section, not interrupted during liquid flow, flow status is stable, improved measuring accuracy, sensor can take out at any time, and it is convenient to clean, and solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: ultrasonic flow rate, calorimeter transducer are " π " type with the pipe internal channel of π type pipeline section, be that fluid passage forms one section beeline channel through the break-in of twice 90 ° of same sense of rotation in the pipeline section in pipeline section between twice break-in.
Be provided with mounting hole on the pipeline section wall at beeline channel two ends in " π " type pipeline section, be provided with sensor in the mounting hole, the sensor at two ends is by the corresponding mutually coupling of rectilinear end.
" π " type pipeline section and close with it " U " type pipeline section, and the pipeline section of analogous shape all belongs to the technical scheme of same design with the utility model.
Adopt the utility model, the flowing through channel of fluid to be measured is: liquid is flowed into by the pipeline section inlet earlier, through entering the straight-line segment in the pipeline section body after 90 ° of break-ins, is flowed out by the outlet of the pipeline section body other end after 90 ° of break-ins again.It is less that sensor takies the interior space of pipeline section, and the fluid flow size is guaranteed.When detecting flow, the sensor that is installed in pipeline section body straight-line segment one end sends ultrasonic signal, and the sensor that is installed in the straight-line segment other end receives signal, again by this sensor emission ultrasonic signal, other end sensor receives, and converter calculates fluid flow according to the ultrasonic signal that obtains.Fluid flow is stable in the π type structure pipeline section, and signal fluctuation is little, thereby has improved measuring accuracy.In use for some time, sensor cleans if scale formation can be taken out sensor easily from the two ends, the left and right sides of pipeline section body, and π type structure pipeline section has solved the not problem of easy cleaning of sensor fouling.
The utlity model has rational in infrastructure, increase the fluid to be measured flow, improve measuring accuracy, clean characteristics such as convenient, overcome the shortcoming of prior art, adopt π type structure pipeline section, increased the flow of fluid to be measured in the test pipeline section, improved measuring accuracy, make things convenient for sensor to clean, can be widely used in ultrasonic flow rate, calorimetric transducer.
