Installation pores for the transducer are oppositely arranged on the wall of the main body of the tube section, and are in acute angle distribution with respect to the main body of the tube section, the probe of the transducer is recessed into installation pores of the transducer, and the central line of the probe overlaps with the central line of the transducer. No obstacle is provided in the cavity of the measurement tube section, so that the flowing state of the fluid is stable, the measurement precision is high, no turbulence is generated, the difficulty of flow computation is reduced, and the precision of the measurement is enhanced. The ultrasonic wave is not reflected, so that the energy loss is little, and the measurement precision is high. The machining process is easy, the assembling and the maintenance process are convenient, and the machining precision is high. The utility model can be used as the dedicated measurement tube section for the transducer of the ultrasonic heat meter for measuring the flow of fluid inside the tube, and heat metering.
Description
Technical field
The utility model relates to the technical field of utilizing interior fluid flow of ultrasonic measurement pipeline or heat, specifically, is that a kind of ultrasonic calorimeter transducer is measured pipeline section.
Background technology
Present existing ultrasonic calorimeter is measured pipeline section, generally all include body, first ultrasonic transducer, second ultrasonic transducer, as the patent No. is the Chinese utility model patent " a kind of ultrasonic water, calorimeter are with measuring pipeline section " of ZL2009203067455, just comprise above-mentioned basic composition, the center line of its two sensors, just the installation direction of sensor probe is not parallel with ultrasonic emitting, receive direction, and is mutually vertical or acutangulate.The a pair of transducer of this utility model patent product is easy to generate and departs from emission, when receiving, can not guarantee on same straight line, thereby can be influential to measuring accuracy; Two transducer mount pad difficulty of processing of its ultrasonic measurement pipeline section are big, and passing rate of processing is low, and machining precision is difficult to assurance, thereby influence the measuring accuracy when using.
The utility model content
The technical problems to be solved in the utility model, provide a kind of transducer installation direction on same straight line, ultrasonic wave propagation path is that linear ultrasonic calorimeter transducer is measured pipeline section, the mounting center line of transducer overlaps with ultrasonic emitting, reception line, clear in the tube chamber, the flow state of fluid is stable, does not produce turbulent flow, reduce the flow rate calculation difficulty, improve accuracy of measurement; Ultrasound wave is without reflection, and energy loss is little, the measuring accuracy height; Handling ease, assembling and easy to maintenance, machining precision height.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of ultrasonic calorimeter transducer is measured pipeline section, comprise circular straighttube pipeline section main body, described pipeline section main body is provided with temperature probe mounting hole and paired transducer mounting hole, paired transducer position of mounting hole relatively is located on the pipeline section main wall and is acute angle with the pipeline section main body respectively and distributes, and transducer is located in the transducer mounting hole; Probe on the transducer sinks in the transducer mounting hole, and the line of centres of two transducer probes and the center line of transducer coincide.
Foregoing is a basic structure of the present utility model, and probe is located in the transducer mounting hole, and fluid passage is accessible, guarantees that liquid flow does not produce turbulent flow, and dependable flow and flow speed stability have improved measuring accuracy, have reduced the difficulty in computation of flow; Ultrasonic emitting and reception are same straight line, without reflection, can reduce energy loss, improve measuring accuracy; Handling ease, assembling and easy to maintenance, machining precision height; Transducer can take out at any time and clean, and guarantees the cleaning of transducer, can further reduce the pressure loss, improves measuring accuracy; Also be suitable for the measurement of small-caliber pipeline inner fluid flow.
As a kind of optimization of the present utility model, described acute angle is 15～60 °.
Because this acute angle is too little, the installation of transducer is not easy to operate; And this acute angle is too big, and hyperacoustic measuring route is too short, the precision that influence is measured.The best value of therefore selected acute angle is 15～60 °.If caliber is bigger, above-mentioned scope all is suitable for; If caliber is less, this acute angle should value be above-mentioned scope smaller value.
Owing to adopted above-mentioned technical scheme, the obtained technical progress of the utility model is:
Fluid passage does not have any obstacle, guarantees that liquid flow does not produce turbulent flow, and flow and flow speed stability have improved measuring accuracy, have reduced the difficulty in computation of flow; Ultrasonic emitting and reception are same straight line, without reflection, can reduce energy loss, improve measuring accuracy; Handling ease, assembling and easy to maintenance, machining precision height; Transducer can take out at any time and clean, and guarantees the cleaning of transducer, can further reduce the pressure loss, improves measuring accuracy; Also be suitable for the measurement of small-caliber pipeline inner fluid flow.The utility model can be used as the dedicated transducer of the ultrasonic calorimeter of fluid flow, heat metering in the measuring channel and measures pipeline section.
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
