Description
Technical field
The utility model belongs to ultrasonic water meter field, and in particular to ultrasonic measurement pipe segment structure.
Background technique
Nowadays, supersonic technique has been widely used in water meter industry, supersonic technique pipeline section type ultrasound
Wave is with " speed difference method " for principle, measures fluid flow in round tube.It uses advanced multi-pulse techniques, signal digitizes
Processing technique and error correcting technique, adapt to the environment of industry spot, and metering is more convenient, economical, accurate.
But when due to using ultrasonic measurement flow, there are other parts in most of flowtubes, will increase the pressure loss,
The generation and sinuous flow phenomenon for not only causing water flow vortex can also cause in flow field laminar flow is unstable to make its generate much noise to increase
The difficulty of signal digitized processing, the precision of the metering finally influenced.
Summary of the invention
Utility model aims to solve prior art deficiencies, provide a kind of measurement pipeline section of ultrasonic water meter, have
Effect avoids the sinuous flow phenomenon in measurement pipeline section, reduces the generation of vortex, forms stable flow field, keep its crushing low, noise is few, has
Effect measurement distance, improves measuring accuracy.
The technical solution of the utility model is as follows:
The utility model proposes a kind of measurement pipeline sections of ultrasonic water meter comprising flowtube, tube core and two ultrasonic waves
Energy converter.It is characterized in that the tube core is embedded in flowtube, ultrasonic transducer mounting hole is offered in flowtube, and
Through tube core, two ultrasonic transducers are mounted in ultrasonic transducer mounting hole to penetrating in parallel；The water flow of the tube core is logical
Road from flow inlet end and outlet end to intermediate measured place by section be round gradually gradual change be punctured into section be it is rectangular again by
Graduate into round.
Further, the flowtube arrival end is equipped with guide groove, is equipped with limited post, pipe in tube core corresponding position engaged therewith
Core is embedded in flowtube by the interference fit of guide groove and limited post.
Further, energy converter is fixed in mounting hole by the ultrasonic transducer by clamp nut.
The utility model also proposes a kind of ultrasonic water meter comprising above-described measurement pipeline section, the measurement pipeline section
Flowtube be connected on water pipe, the signal of ultrasonic transducer is connected to the electronical display gauge outfit of ultrasonic water meter by lead
On.
The utility model proposes above-mentioned measurement pipe, due to being embedded in tube core in flowtube, tube core is voluntarily special designing
Structure, not only there is rectification function, the also effective stabilization for increasing flow field laminar flow, greatly reduction crushing, the energy converter of growth

1 interference fit is embedded in flowtube 1.Due to, without other odd parts, keeping its easy for installation, and effectively reduce in tube core
The pressure loss increases effectively measurement distance.
In the present solution, 3 mounting means of ultrasonic transducer are as follows: referring to Fig. 3, there are two energy converters for processing in flowtube 1
Mounting hole 1-1, energy converter mounting hole 1-1 will run through tube core 2, and energy converter 3 is fixed in mounting hole 1-1 with clamp nut 4.
In the present solution, referring to fig. 4, Fig. 5 and Fig. 6, the water stream channel of tube core 2 is from flow inlet end and outlet end to intermediate
The special construction that measured place is formed by particular curve 2-1 gradual change, the structure are to become similar rectangular 2-4 from round 2-3 gradual change
Structure, this structure design not only have rectification function, and the also effective stabilization for increasing flow field laminar flow reduces the shape of water flow vortex
At reducing the generation of noise.
