Abstract
The utility model provides a reflection-type ultrasonic calorimeter flow tube which comprises a rube body, a water inlet end, a water outlet end, a temperature sensor A, a temperature sensor B, an ultrasonic transducer A, an ultrasonic transducer B, a reflection plate A, a reflection plate B, a supporting frame and a fixing plate. The reflection-type ultrasonic calorimeter flow tube is characterized in that the reflection plate A is arranged under the ultrasonic transducer A, the reflection plate B is arranged under the ultrasonic transducer B, outer surfaces of the ultrasonic transducer A, the ultrasonic transducer B, the reflection plate A and the reflection plate B are all provided with hydrophobicity coatings, and the supporting frame and the fixing plate are made of all-metal materials. The arrangement of the hydrophobicity coatings avoids accumulation of scale, and therefore service life of products is prolonged. The reflection plates, the supporting frame and the fixing plate are made of the all-metal materials so that the problem of changes of ultrasonic sonic paths and signal reflection angles caused by different coefficients of thermal expansion is avoided effectively, and precision of measurement is further guaranteed.
Description
Technical field
The utility model relates to instrument field, relates in particular to a kind of heat quantity flow pipe.
Background technology
The measuring ultrasonic wave flow technology is used on the calorimeter and reaches its maturity at present, and is wherein especially more general with reflective application.Domestic ultrasonic calorimeter generally adopts built-in working of plastics form that hyperacoustic signal reflex plate is fixed, because working of plastics is different from the thermal expansivity of metal shell, cause ultrasound wave sound path, signal reflex angle etc. to change, cause metering inaccurate, the medical unstable series of problems that waits.Carrying out heat conducting in the flowtube is water, and the dust in the water and impurity are easy to hang on reflecting plate and fouling, and longer fouling working time is thicker, affects hyperacoustic reflection and causes measuring and inaccurately maybe can't measure.
Summary of the invention
In order to address the above problem, it is simple in structure that the utility model provides, measuring accuracy is high, a kind of reflection-type ultrasonic wave heat meter flowtube of long service life, comprise body, be arranged on water inlet end and the water side at body two ends, be arranged on the temperature sensor A of water inlet end, be arranged on the temperature sensor B of water side, be arranged on ultrasonic transducer A and the ultrasonic transducer B of inner surface of tube body, be arranged on reflecting plate A and reflecting plate B in the body, be arranged on the bracing frame of reflecting plate A and reflecting plate B bottom, be arranged on the fixed head between body and the bracing frame, it is characterized in that described reflecting plate A is arranged on the below of ultrasonic transducer A, described reflecting plate B is arranged on the below of ultrasonic transducer B, ultrasonic transducer A, ultrasonic transducer B, reflecting plate A, be provided with the hydrophobic coating layer on the outside surface of reflecting plate B, described bracing frame, fixed head is the all-metal material.
The beneficial effects of the utility model are: the utility model on the outside surface of ultrasonic transducer A, ultrasonic transducer B and the outside surface of reflecting plate A, reflecting plate B be provided with the hydrophobic coating layer, so that the heating installation current can not accumulate incrustation scale at the outside surface of ultrasonic transducer A, ultrasonic transducer B and reflecting plate A, reflecting plate B when flowing through body, thereby prolonged the serviceable life of product; Reflecting plate bracing frame, fixed head adopt the all-metal material, have effectively avoided thermal expansivity different and the problem that causes ultrasound wave sound path, signal reflex angle to change has further guaranteed the precision of measuring.
