Description
Technical field
the utility model relates to the flow measurement device technical field, is that a kind of ultrasonic calorimeter is with the reflective flowtube of N type.
Background technology
are present, and the measuring ultrasonic wave flow technology is used on the calorimeter very ripe, wherein more general with reflective application especially; Generally comprising flowtube, catoptron, ultrasonic transmission device and WT-MSR constitutes; Wherein, catoptron mainly contains two kinds of mounting meanss, and a kind of is mounting bracket in flowtube; Catoptron is installed on support, and catoptron is a schistose texture; A kind of is on flowtube, to punch, and catoptron is installed in the hole, and catoptron is column structure (reflecting surface is the inclined-plane).See from the reflection mode and to mainly contain following three kinds at present: first kind is the reflection of U type, and second kind be the V-type mode, and the third is a W type mode, and these three kinds reflect the mode ultrasonic transducer all in the same side of flowtube.Because calorimeter all can fouling on catoptron or flowtube inboard wall of tube body after reality is used a period of time, and working time, long more fouling was thick more, finally caused stopping up, metering is inaccurate maybe can't measure.Though it is removable that catoptron is arranged now, when needing catoptron to be pulled down and clean, the catoptron dismounting is complicated, the erecting stage operating difficulties, and on-the-spot dismounting catoptron also can exert an influence to the measuring accuracy of product, also needs detect again product.Therefore, calorimeter should reduce the condiment that hinders hot water flow in the flowtube as much as possible when design, helps reducing crushing, reduces and stop up, and improves the serviceable life of calorimeter.
The utility model content
The purpose of
the utility model is the deficiency to prior art, provides a kind of rational in infrastructure, and the ultrasonic reflections number of times is few, and measuring accuracy is high, and the little a kind of ultrasonic calorimeter of the pressure loss is with the reflective flowtube of N type.
realize that the technical scheme that above-mentioned purpose is taked is: a kind of ultrasonic calorimeter is with the reflective flowtube of N type; It comprises body; On body, be provided with entery and delivery port, ultrasonic reflections mirror, transducer mounting hole and pairing temperature sensor mounting hole; It is characterized in that: on the body between the entery and delivery port, be provided with the first ultrasonic transducer mounting hole and the second ultrasonic transducer mounting hole; The first ultrasonic transducer mounting hole and the second ultrasonic transducer mounting hole place the both sides of body respectively; Be provided with the first columnar ultrasound wave reflection mirror on the opposite of the first ultrasonic transducer mounting hole, be provided with the second columnar ultrasound wave reflection mirror on the opposite of the second ultrasonic transducer mounting hole, the ultrasonic reflections route is the N type.
The reflecting surface center of
said first columnar ultrasound wave reflection mirror and the reflecting surface center of the second columnar ultrasound wave reflection mirror all are lower than the body center line, and the mid point of N type reflection route is through the central point of body.
the said first columnar ultrasound wave reflection mirror minute surface and the second columnar ultrasound wave reflection mirror minute surface are an inclined-plane, and the angle of reflecting surface and center line is less than 45 °.
The ultrasonic calorimeter of
the utility model is with the reflective flowtube of N type, owing to adopt N type reflection mode, the first ultrasonic transducer mounting hole and the second ultrasonic transducer mounting hole lay respectively at the both sides of body; The reflecting surface center of the reflecting surface center of the first columnar ultrasound wave reflection mirror and the second columnar ultrasound wave reflection mirror all is lower than the body center line; Can obviously reduce resistance, help reducing crushing, reduce and stop up hot water; Improved the serviceable life of calorimeter; Reduced the operation expense of calorimeter, be particularly suitable for the heat supply water quality inferiority, the environment that is prone to fouling uses.
