Problems solved by technology

Most of the existing ultrasonic calorimeters have reflective surfaces. The Chinese patent announcement date is 2014.01.01 and the announcement number is CN203376082U, which provides an ultrasonic calorimeter column type spherical expansion base meter with high measurement accuracy. , but impurities are easy to precipitate in the pipe section. After the reflection surface is fouled, it will cause errors and attenuation of the reflection of the sound wave, which will affect the signal transmission, or even completely lose the sound wave signal, thereby affecting the measurement accuracy.

Abstract

The present invention provides a column-type spherical expanding base meter tube for an ultrasonic heat meter. The column-type spherical expanding base meter tube for the ultrasonic heat meter comprises a tube section body, two reflection columns, two transducer mounting holes arranged on the tube section body and a temperature sensor mounting hole. The tube section body is provided with two spherical expanding parts which are communicated with each other through a diversion hole; the reflection columns are respectively arranged in the expanding parts; reflection surfaces are respectively arranged at the top portions of the two reflection columns, and the two reflection surfaces are arranged opposite to each other; the transducer mounting holes are respectively disposed opposite to the reflection surfaces; and internal threads are installed on the tube section body, external threads matching the internal threads are installed on the spherical expanding parts, and the spherical expanding parts are threadedly connected with the tube section body. With increasing usage time of an ultrasonic heat meter, the column-type spherical expanding base meter tube for ultrasonic heat meter is able to timely remove dirt in a tube section body, effectively remove residue matters on reflection surfaces, and improve the measurement precision of the ultrasonic heat meter; and moreover, the structure is simple, the decontamination is easy, the measurement precision is high and the service life is long.

Description

technical field [0001] The invention belongs to the field of ultrasonic heat meters, and in particular relates to a column type spherical expansion base tube of an ultrasonic heat meter. Background technique [0002] The ultrasonic heat meter is an instrument that measures the flow rate and displays the heat released or absorbed by the water flowing through the heat exchange system by means of ultrasonic waves. Ultrasonic heat meters work on the principle of ultrasonic time-of-flight and are widely used in many fields. Most of the existing ultrasonic calorimeters have reflective surfaces. The Chinese patent announcement date is 2014.01.01 and the announcement number is CN203376082U, which provides an ultrasonic calorimeter column type spherical expansion base meter with high measurement accuracy. , but impurities are easy to precipitate in the pipe section. After the reflection surface is fouled, it will cause errors and attenuation of the reflection of the sound wave, whic...
