The utility model is characterized in that installation positioning slots (8 and 9) are arranged inside a measuring pipe segment along the direction in which the liquid flows; reflecting bodies (2 and 3) are respectively fixed in the installation positioning slots (8 and 9) through position clamps (10 and 11), and the reflecting bodies (2 and 3) are respectively flaky. The flaky reflecting bodies occupy small space in the pipe segment; therefore, the flowrate of the liquid can be guaranteed, the flowrate of the liquid is stable, signal fluctuation is small and thus measuring accuracy is raised. After the utility model is used for a period of time, if the reflecting bodies generate the phenomenon of deposition, the reflecting bodies can be conveniently disassembled from both ends of the pipe segment so as to be cleaned and thus the problem that the deposition of the reflecting bodies is not easily cleaned is successfully solved. The measuring pipe segment enlarges the flowrate of the liquid in a testing pipe segment, raises measuring precision and facilitates the cleanness of sensors. The utility model can be used for the converters of ultrasonic flowmeters and calorimeters.

Description

Ultrasonic flow rate, Calorimeter Converter Using For Measuring Pipe Run
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 converter of fluid flow or heat is applicable to the metering of fluid flow, heat in the little caliber in the metering pipeline.
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, 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 Conversion device 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, 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 Converter Using For Measuring Pipe Run, 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: the composition of ultrasonic flow rate, Calorimeter Converter Using For Measuring Pipe Run comprises pipeline section wall, sensor mounting hole, the sensor mounting hole is arranged on the pipeline section wall, with pipeline section endoporus UNICOM, along liquid flow direction the installing and locating groove is set at the measuring tube intersegmental part, reflecting body is arranged on by the installing and locating groove and measures in the pipeline section.
Reflecting body is sheet preferably.The measuring tube intersegmental part can be together along the installing and locating groove of liquid flow direction setting, also can be multiple tracks, and preferably the corresponding mutually installing and locating groove of twice is one group, makes together when the in-process measurement pipeline section; Locator card is set on the reflecting body, locator card one end is fixed on the reflecting body, the other end is stuck in the installing and locating groove, a locator card can be set on reflecting body, also a plurality of locator cards can be set, two locator cards preferably are set on reflecting body, are complementary with one group of installing and locating groove on the pipeline section wall, two locator cards are stuck in the twice locating slot of mutual correspondence; Reflecting body and locator card are as a whole, together processing and fabricating.
Because the large volume reflecting body of abandoning tradition is along the mode of installing perpendicular to the sensor mounting hole of pipeline section, employing is opened along liquid flow direction at the measuring tube intersegmental part and is got the installing and locating groove, the utility model can use the less platelet-like reflective body of volume to install along the installing and locating groove, takies less space in the pipeline section.
When adopting the utility model to detect flow, measuring-signal is passed to sensor through two secondary reflections of reflecting body, and transducer calculates fluid flow according to the ultrasonic signal that obtains.The interior space of pipeline section is less because the platelet-like reflective body that adopts takies, and the fluid flow size is guaranteed, and fluid flow is stable, and signal fluctuation is little, thereby has improved measuring accuracy.In use for some time, reflecting body cleans if scale formation can be taken out reflecting body easily from the two ends, the left and right sides of pipeline section body, successful solution the reflecting body fouling problem of easy cleaning not.
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 this structure measurement 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 converter.
