But existing ultrasonic calorimeter generally is made up of sensor housing, transducer, reverberator, and structure is comparatively complicated.Wherein, transducer, reverberator need accurately corresponding, could guarantee best reflection angle.And the existence of reverberator also can cause extra pressure loss.In addition, the impurity that is contained in the current can be deposited on the ultrasonic calorimeter inner chamber, forms incrustation scale, influences measuring accuracy.
Summary of the invention
The present invention is directed to existing ultrasonic calorimeter complex structure, reverberator can cause extra pressure infringement, and inner chamber is not easy to shortcomings such as cleaning, provides a kind of simple in structure, and degree of accuracy is high, the new type ultrasonic calorimeter of convenient disassembly.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
Ultrasonic calorimeter comprises ultrasonic transducer, sensor housing, and said sensor housing takes the shape of the letter U; The two ends of sensor housing connect water inlet pipe and water outlet pipe; The sensor housing knee is symmetrically arranged with two through holes, and through hole is provided with the capping that is used to seal, and capping is provided with body; One end of body stretches into sensor housing inside; The other end of body is positioned at the sensor shell external, and said ultrasonic transducer is arranged on body and is positioned at the inner end of sensor housing, and two bodys are in same straight line.
As preferably; Said ultrasonic transducer comprises piezoelectric ceramic vibrator, goes up compressing tablet, lower sheeting; Piezoelectric ceramic vibrator is between last compressing tablet and lower sheeting, and piezoelectric ceramic vibrator is fixedly connected with lower sheeting, and said upward compressing tablet and lower sheeting are formed by the folding back of sheet metal.
As preferably, the said material of going up compressing tablet and lower sheeting is a steel disc.
As preferably, the radial section of said body is rounded or oval.
As preferably, be surrounded with O-ring seal around the said ultrasonic transducer, an end of body is provided with the end cap that is used to press ultrasonic transducer and O-ring seal, and the center of end cap is provided with through hole.
As preferably, also comprise main, the two ends of main connect water inlet pipe and water outlet pipe, and a side of main is provided with two connecting holes, and connecting hole connects the two ends of sensor housing respectively, and main is connected through connecting hole with sensor housing.
As preferably, said connecting hole is provided with valve.
The present invention has significant technique effect owing to adopted above technical scheme:
The structure that employing is oppositely arranged two ultrasonic transducers; The ultrasonic signal that ultrasonic transducer sent can directly arrive another ultrasonic transducer; The centre need not reverberator and reflects, and not only can omit reverberator, avoids the obstruction of reverberator to current; Reduced the depletion of ultrasonic calorimeter, simplified the structure of ultrasonic calorimeter pressure; Can also reduce because the problem of the signal depletion that reflection brings.
The body that is used for the bearing ultrasonic transducer has cylindrical smooth surface, and is little to the stirring of current, little to the influence of hydraulic pressure.Therefore body is arranged in the capping of sensor housing both sides, just can take out body easily as long as unload capping, is convenient to overhaul and operation such as maintenance.In addition, ultrasonic transducer is arranged on body one end, and therefore as long as two bodys can come body is adjusted point-blank through the adjustment capping.
For further aspect dismounting, this ultrasonic calorimeter can also be arranged on the branch road of water pipe, can pass through the valve controlled water flow, and the operation of dismounting ultrasonic calorimeter can not influence current, guarantees dismounting in real time.
