Abstract
The utility model discloses a metering device for an ultrasonic heat meter in a low-column reflection mode. The device comprises a tube body (1), two transducers (2 and 3) and two small-angle reflecting blocks (4 and 6), wherein a rectification adjusting reflecting block (5) is arranged between the two transducers (2 and 3), so that ultrasonic waves emitted from one transducer can be received by the other transducer after being reflected by the two small-angle reflecting blocks and the rectification adjusting reflecting block. According to the device, low-column reflection is adopted, so that three-level reflection are formed by signals in the tube body, the signal reflection distance is lengthened, and collected signals are stable.
Description
Technical field
The utility model relates to ultrasound wave heat metering instrument device, particularly the ultrasound wave of ultrasound wave heat metering instrument device metering device.
Background technology
Ultrasonic calorimeter is measured flow through hyperacoustic method and is shown that current discharge or absorb the instrument of thermal energy through heat-exchange system.The flow of the physical quantity that it records through two kinds of sensors---thermal barrier and the temperature of import and export, the compensation and the integral and calculating of passing through density and heat enthalpy value more just can obtain calorie value.It is a kind of electromechanical integrated product that is the basis with microprocessor and high-precision sensor.Use gauging table with the family that building industry is generally used in the past---water meter, ammeter, gas meter are compared, and more complicated design and higher technology content are arranged.
Traditional ultrasound wave heat metering instrument device has following several kinds of shortcomings: 1, its shortcoming is to cause dirt deposition influence reflection because ducted current contain long-term use of a large amount of dirts to the square through type transducer reflection unit of traditional ultrasound wave heat metering instrument device in the tube wall bottom.2, the material of pipeline section part is that tube material is worn into the plane of reflection easily in the hot water of long-term relatively poor water quality washes away and is uneven, thus influence acoustic reflection and since tiltedly the transducer installation be easy to generate bubble and influence acoustic reflection.3, high its shortcoming of column reflection that usually adopts is high column mobile inhibition that plays to current in pipeline, and the turbulent flow influence is measured and the rising of temperature changes thereby produce when making the current water inlet.
Summary of the invention
For solving the problems of the technologies described above; The utility model provides a kind of ultrasound wave heat metering instrument device of low column reflection mode; Its objective is reduce column at ducted height to reduce inhibition to current, the collection that prolongs signal simultaneously is apart from improving signal stabilization.
The technical scheme that the utility model adopts is: a kind of ultrasound wave heat metering instrument device of low column reflection mode; It comprises body, transducer and low-angle reflex block; Said transducer has two to be separately fixed on the pipe body lumen wall; Said low-angle reflex block has two belows that lay respectively at transducer, and the low-angle reflex block is provided with reflecting slant, and the reflecting slant of two low-angle reflex blocks is relative; Be fixed with rectification accommodation reflex piece on the tube cavity tube wall between described two transducers, make the ultrasound wave that sends from a transducer after low-angle reflex block and the reflection of rectification accommodation reflex piece, can be received by another transducer.
Further improve, the inclination angle angle of the reflecting slant of described low-angle reflex block is 70 degree.
Further improve, the tube wall inner chamber bottom surface of the reflecting slant lower end horizontal plane of described low-angle reflex block and body is positioned on the same plane.
The beneficial effect that the utility model is obtained is that the utility model adopts low having reduced of low column reflective face to influence less to the inhibition of ducted fluid to flow; Tube wall is provided with rectification accommodation reflex piece and makes and in body, form tertiary reflex by signal to elongate signal reflex more stable apart from acquired signal; Low reflection post bevel angle is bigger, is convenient to installation and maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Present embodiment such as Fig. 1 are said; It comprises body 1, two 2,3 and two low- angle reflex blocks 4,6 of transducer; Transducer 2,3 is separately fixed on the pipe body lumen wall, and present embodiment is on the wall of body 1, to connect two short tubes that pass through mutually, and transducer 2,3 is separately fixed in two short tubes.Low- angle reflex block 4,6 is positioned at the below of transducer 2,3; 4,6 insertions of low-angle reflex block are arranged in the recessed downwards recessed channel of body 1 and realize fixing; 4,6 are provided with reflecting slant on the low-angle reflex block; The reflecting slant of two low- angle reflex blocks 4,6 is relative, is fixed with rectification accommodation reflex piece 5 on the tube cavity tube wall between two transducers, and the rectification accommodation reflex piece 5 of present embodiment is to be fixed on the body in 1 through hole offered; It is the stainless steel reflex block, makes the ultrasound wave that sends from a transducer after low-angle reflex block and the reflection of rectification accommodation reflex piece, can be received by another transducer like this.The inclination angle angle of the reflecting slant of preferred low-angle reflex block is 70 degree.For the tube wall inner chamber bottom surface of reducing special reflecting slant lower end horizontal plane that makes described low-angle reflex block of column inhibition in pipeline and body is positioned on the same plane.
Claims (3)
1. one kind low column reflects the ultrasound wave heat metering instrument device of mode; It comprises body (1), two transducers (2,3) and two low-angle reflex blocks (4,6); Said transducer (2,3) is separately fixed on the wall of body (1) chamber; Said low-angle reflex block (4,6) lays respectively at the below of transducer (2,3); Low-angle reflex block (4,6) is provided with reflecting slant; The reflecting slant of two low-angle reflex blocks (4,6) is relative, it is characterized in that being fixed with rectification accommodation reflex piece (5) on body (1) the inner chamber tube wall between described two transducers (2,3), makes the ultrasound wave that sends from a transducer after two low-angle reflex blocks and the reflection of rectification accommodation reflex piece, can be received by another transducer.
