Abstract
The utility model discloses a novel reflective tapered ultrasonic calorimeter base table, comprising a base table shell, a mounting hole and an ultrasonic reflection body. The key points of the novel reflective tapered ultrasonic calorimeter base table are as follows: an ultrasonic transducer is arranged in the mounting hole, and a sealing ring is arranged between the lower part of the ultrasonic transducer and the base table shell; a cushion plate and a press plate are sequentially arranged above the ultrasonic reflection body; the ultrasonic reflection body is arranged in a tapered base table channel; the central axial lines of the ultrasonic reflection body and the ultrasonic transducer correspond up and down; and an included angle between the reflection surface of the ultrasonic reflection body and the horizontal surface of the base table channel is 45 degrees. The novel reflective tapered ultrasonic calorimeter base table disclosed by the utility model has the advantages of reasonable structure design, convenience for manufacturing and good reflection effect, and solves the technical problems of complex structure, high production cost, short service life and low measurement precision in the prior art.
Description
Technical field the utility model belongs to the measuring instrument technical field, is specifically related to a kind of new type reflection formula convergent ultrasonic calorimeter base table that is used for heating metering.
The ultrasound wave family of using in the background technology prior art mainly contains V method and W method with the reflection mode of calorimeter; These two kinds of method for reflection all will carry out the pipeline wall reflection of one or many, thereby because the influence of factors such as the material of pipeline wall and surfaceness has caused directivity and the intensity of ultrasound wave ray is not ideal very.Consider based on this point; The manufacturer that has has produced the ultrasonic calorimeter that in the base table pipeline, installs the ultrasonic reflections device additional; Ultrasonic reflections sheet and variable cross section passage have been installed in its base table flow channels; Can overcome above-mentioned shortcoming, but this calorimeter structure relative complex, and production difficulty and cost are higher relatively; Exist big, the inner plastic components temperature distortion of the pressure loss aging simultaneously, serviceable life is short; And precision is low when measuring for a long time.
The purpose of summary of the invention the utility model provides a kind of new type reflection formula convergent ultrasonic calorimeter base table, in order to overcome the technical matters that the existing complex structure of prior art, production cost are high, serviceable life is short and measuring accuracy is low effectively.
To achieve these goals, the reflective convergent ultrasonic calorimeter of the utility model base table, it comprises base table watchcase, mounting hole and ultrasound reflector; Its main points are to be provided with ultrasonic transducer in the said mounting hole, are provided with O-ring seal between the below of said ultrasonic transducer and the base table watchcase; Said ultrasonic transducer top is provided with backing plate and pressing plate successively; Said ultrasound reflector is arranged in the tapering type base table passage; Said ultrasound reflector is corresponding up and down with the central axis of ultrasonic transducer; The surface level of the reflecting surface of said ultrasound reflector and base table passage is 45 ° of angles.
Said ultrasound reflector by screw retention in the base table passage.
The utility model reasonable in design, easy to make, reflecting effect good.During calorimeter work; The ultrasound reflector of the vertical directive of ultrasonic transducer ultrasonic waves transmitted under it; Because the reflecting surface of ultrasound reflector is horizontal by 45 ° of angles; Therefore ultrasound reflector can reflex to the ultrasound wave along continuous straight runs on the ultrasound reflector of the base table passage other end, and this ultrasound reflector is equally horizontal by 45 ° of angles, thus ultrasonic reflections to receiving transducer; The reflection trace of ultrasound wave ray is " U " type, has so just accomplished the measurement of a ultrasonic propagation time difference.The utility model has solved prior art and has had complex structure, production cost is high, serviceable life is short and measuring accuracy is low technical matters.
Appended drawings is the main cut-open view of looking of the utility model structural representation.
Among the figure 1, base table watchcase 2, ultrasound reflector 3, mounting hole 4, O-ring seal 5, ultrasonic transducer 6, backing plate 7, pressing plate
Embodiment is as shown in the figure, and it comprises base table watchcase 1, mounting hole 3 and ultrasound reflector 2 the utility model; Be provided with ultrasonic transducer 5 in the said mounting hole 3, be provided with O-ring seal 4 between the below of said ultrasonic transducer 5 and the base table watchcase 1; Said ultrasonic transducer 5 tops are provided with backing plate 6 and pressing plate 7 successively; Said ultrasound reflector 2 is arranged in the tapering type base table passage; Said ultrasound reflector 2 is corresponding up and down with the central axis of ultrasonic transducer 5; The surface level of the reflecting surface of said ultrasound reflector 2 and base table passage is 45 ° of angles; Said ultrasound reflector 2 by screw retention in the base table passage.
The ultrasound reflector of the utility model is simple in structure; Ultrasound reflector is processed and independent installation by stainless steel material; Have characteristics corrosion-resistant, no resonance; Stop phenomenons such as inner plastic components distortion is aging, reflecting surface skew, improved the reflection strength and the directivity of ultrasound wave ray effectively, can guarantee measuring accuracy for a long time; The base table flow channels is tapering type structure, and inner no-movable part and magnetic part do not have wearing and tearing, are difficult for stopping up, and the pressure loss is little, long service life; Overall package easily, cost is lower, measurement is accurate.
Test shows, the utility model ultrasonic calorimeter, reliable operation, its precision can satisfy the measuring requirement of relevant national standard, and have installation, advantage easy to use.
