Abstract
The utility model discloses a kind of constitutional detail for improving the big stream of ultrasonic wave, small stream error, including body, it is characterized in that, link buckle is provided with the outside of the body upper end, the link cards detain side left end and are provided with limit rib, the limit rib is located at the front side of body, and positioning bar is provided with the right side of the body lower end.The utility model can improve the direction that gas enters gas meter, flow meter, while will not entering gas, also into transducer, cause resultant turbulence, and influence big stream, the error in dipping of rill, make metering more accurate.
Description
Technical field
Gas meter, flow meter field is the utility model is related to, it is specifically a kind of to improve the big stream of ultrasonic wave, the constitutional detail of small stream error.
Background technology
With the improvement of living standards with the reinforcement of environmental consciousness, the daily fuel cooked of people is from firewood, coal
Etc. serious waste of resources, with serious pollution conventional energy resource is changed into using natural gas and coal gas, the even clean energy resource such as electricity.
Gas meter, flow meter will play its effect herein, have its automatic accumulating function so that those use natural gas or pipeline coal
Gas other, easily can know how much gas used, so as to can according to monthly consume combustion gas cubic meter number pay the fees.
Ultrasonic transducer is a kind of energy conversion device, and its function is that the electrical power of input is converted into mechanical output
（That is ultrasonic wave）Pass again, and a part of power that autophage is seldom.The application of ultrasonic transducer is quite varied, it
It is divided into industry, agricultural, communications and transportation, life, medical treatment and military affairs etc. by the industry of application.
But present gas meter, flow meter, also into transducer, causes resultant turbulence while gas enters watchcase, and influence
Big stream, the error in dipping of rill, influence to measure.Therefore, those skilled in the art provide a kind of big stream of improvement ultrasonic wave, rill
The constitutional detail of error, to solve the problems mentioned in the above background technology.
The content of the invention
The purpose of this utility model is to provide a kind of big stream of improvement ultrasonic wave, the constitutional detail of small stream error, to solve
The problem of being proposed in above-mentioned background technology.
To achieve the above object, the utility model provides following technical scheme：
It is a kind of to improve the big stream of ultrasonic wave, the constitutional detail of small stream error, including body, it is characterised in that on the body
End outside is provided with link buckle, and the link cards detain side left end and are provided with limit rib, and the limit rib is located at the front side of body, institute
State and be provided with positioning bar on the right side of body lower end.
As further program of the utility model：The link buckle is surrounded by recess.
As the utility model further scheme：The link cards detain side and are provided with clip.
Compared with prior art, the beneficial effects of the utility model are：The utility model is fixed on air inlet connecting by buckle
In the groove of head, by limit rib and positioning bar, ensure that position is correct, will not rotate or offset, gas passes through the tracheae baffle plate
After guiding, orderly enters inside gas meter housing, then into transducer, can so improve gas into gas meter, flow meter
Direction, while will not entering gas, also into transducer, cause resultant turbulence, and influence big stream, the metering of rill misses
Difference, make metering more accurate.
Brief description of the drawings
Fig. 1 is a kind of big stream of improvement ultrasonic wave, the structural representation of the constitutional detail of small stream error.
Fig. 2 is a kind of big stream of improvement ultrasonic wave, the structural representation of the constitutional detail sectional view of small stream error.
Fig. 3 is a kind of big stream of improvement ultrasonic wave, the structural representation of the constitutional detail left view of small stream error.
