Abstract
Provided is a base meter of a supersonic heat meter, belonging to the design and manufacture technological fields of base meters of supersonic heat meters. A V-shaped supersonic reflector is arranged in a middle position in the lower of an over-current channel. The base meter of the utility model is a main part of the whole heat meter, wherein supersonic energy transducers are partially mounted in installation holes over the over-current channel to form the whole heat meter. During working, supersonic waves emitted by an emission energy transducer of the heat meter are emitted upon the V-shaped reflector below the emission energy transducer, and then reflected to a reception energy transducer; twice reflection can finish once measurement of transmission time difference of the supersonic waves; and provided heat can be then measured via internal signal processing. The base meter of the supersonic heat meter is simple in structure and reasonable in design; the supersonic reflector is V-shaped and integrated, so that reflection angles thereof are fixed, thereby simplifying both manufacture and installation, and reducing the production cost; the reflection angles are not deviated, thereby greatly improving metering precision; and thus, existing problems in the prior product are solved.
Description
Technical field
The utility model belongs to design and the manufacturing technology field of calorimeter basal meter.
Background technology
The calorimeter that now is used for dwelling unit heating mainly contains U-shaped reflection, V-arrangement reflection and the reflection of W shape according to hyperacoustic reflection trace differentiation.The calorimeter of at present U-shaped reflection uses the most extensive.This calorimeter be in the flow channels of its base table with two ultrasonic reflections posts, with the inclined-plane of one 45 degree, be used for reflection supersonic wave in the inboard of two reflection posts.Make hyperacoustic trend of reflection be the U font.Therefore be called the U-shaped reflection.This base table is very high to the requirement of the surfaceness of installation, the flow channels inwall of reflection post, and inner wall roughness angle large and that the reflection post is installed slightly has deviation, all can have a great impact reflected signal.Also just naturally have influence on measuring accuracy.Therefore improve the difficulty of production and processing, strengthened manufacturing cost.
Summary of the invention
For above-mentioned situation, the purpose of this utility model provides a kind of the manufacturing ultrasonic calorimeter base table simple and that reflecting effect is good is installed.Solve the problem that existing product exists.
The utility model is to address the above problem the technical scheme of taking to be: on the top of flow channels with two ultrasonic transducer mounting holes.The place is with V font ultrasonic reflections sheet in the middle of below flow channels.On the V-shape ultrasonic reflections sheet with nut.The ultrasonic reflections sheet is fixed on the flow channels by nut.The utility model is a critical piece on the overall thermal scale, and the wave transducer that rises to the Western Paradise partly is installed on the mounting hole on flow channels top, namely consists of the overall thermal scale.The using method of this calorimeter is identical with existing calorimeter, and it is installed on the heat supply pipeline.On the V font reflector plate of the ultrasound wave directive of the transmitting transducer of calorimeter emission under it, reflex on the opposite side reflector plate by reflector plate reflection supersonic wave along continuous straight runs during work, reflex to again receiving transducer.Need like this two secondary reflections just to finish the measurement of a ultrasonic propagation time difference.Processing is processed through internal signal again, measures the heat of confessing.The utility model is simple in structure, and is reasonable in design, because the ultrasonic reflections sheet of this product is the V font, and monoblock type, its reflection angle is fixed.No matter therefore be to make, install and all accomplished simplification, reduced manufacturing cost, because there is not deviation in its reflection angle, so measuring accuracy improves greatly.Solved the problem that existing product exists.
