Description
Technical field
The present invention relates to ultrasonic calorimeter or flowmeter, particularly relate to a kind of pipeline section mechanism for using on ultrasonic calorimeter or the flowmeter.
Background technology
Ultrasonic calorimeter and ultrasonic flowmeter all are to adopt the work of ultrasound wave time difference method principle, and ultrasound wave time difference method principle is the mistiming that relies on ultrasonic signal to propagate in fluid, measures fluid flow.When ultrasound wave is propagated in fluid, flowing of fluid will make ultrasonic signal produce the mistiming of propagating, and the flow velocity of time extent and fluid is proportional, thus just measurable flow body flow.For ultrasonic calorimeter, then can increase flow and temperature variation and calculate the heat that heat-exchange system obtains.Ultrasonic calorimeter and ultrasonic flowmeter have all obtained using very widely in a lot of fields.
In current ultrasonic calorimeter and hypersonic flow scale, the pipe segment structure that adopts can be divided into two kinds of reflective and correlations by hyperacoustic round.The ultrasound wave of reflective pipeline section needs just can arrive at other end transducer through the 1-3 secondary reflection after end transducer emission, and the process of this reflection can cause the decay of signal, and simultaneously this reflection also depends critically upon the smoothness of reflecting surface.Therefore for the parts of this reflecting type pipeline section structure, need to guarantee that high machining precision guarantees the accurate and consistance of ultrasonic signal round, will cause like this increase of actual production processing cost, in addition because the impact of domestic water quality environment, in actual use, reflecting surface easily produces the magazine precipitations such as incrustation scale and rust staining, causes the smooth roughness descent of reflecting surface, thereby hyperacoustic propagation stability and validity are produced considerable influence.
The correlation pipe segment structure does not need through reflecting body owing to transducer transmits and receives ultrasonic signal, directly correlation transmitting-receiving, therefore there is not reflective defects, but correlation pipe segment structure in the market is oblique correlation, be the both sides that transducer is installed in respectively the pipeline section axis, cause ultrasonic propagation route and water (flow) direction to produce angle, increased the computation complexity when software is processed, also easily be subject to the interference of tube fluid fluidised form, also cause simultaneously the raw materials consumption amount of pipeline section body, increased cost.Though the pipeline section design that makes the ultrasonic propagation direction parallel with the fluid direction of propagation along the pipeline section center is arranged at present, and its structure complexity is very high, has both increased manufacturing cost, has also increased the assembling complexity, therefore fails to obtain spread in market.
