Abstract
The utility model discloses an anti-scaling ultrasonic flow sensor. The flow sensor comprises a flow pipe, wherein the flow pipe is provided with two ultrasonic energy transducer installation holes in which ultrasonic energy transducers are arranged; a flow pipe core is arranged in the flow pipe; the lower end faces of the two ultrasonic energy transducers are provided with energy transducer Teflon coatings; a first reflecting sheet, a second reflecting sheet and a third reflecting sheet are arranged in the flow pipe core; and the reflecting surfaces of the first reflecting sheet, the second reflecting sheet and the third reflecting sheet are provided with reflecting sheet Teflon coatings. The flow sensor has a simple and novel structure; and the service life of the flow sensor is prolonged and the measuring accuracy of the flow sensor is enhanced by performing anti-scaling treatment on an important component in the ultrasonic flow sensor, namely, arranging a layer of Teflon coating.
Description
Technical field
The utility model relates to a kind of physical measuring instrument, particularly relates to a kind of good antiscale property ultrasonic flow sensor.
Background technology
Existing ultrasonic flow sensor, all be difficult to avoid the scale problems of sensor internal parts, reason is because ultrasonic transducer and reflector plate etc. are immersed in the liquid for a long time, time has been grown, sediment in the liquid will so can weaken the sensitivity and the data veracity of measurement greatly attached on the parts that are positioned at flowtube.
Summary of the invention
Thereby the purpose of this utility model provides a kind of good antiscale property ultrasonic flow sensor that can prevent sensor internal parts fouling raising measuring accuracy.
For achieving the above object, the technical solution of the utility model is: the good antiscale property ultrasonic flow sensor of design, comprise flowtube, on this flowtube, have two ultrasonic transducer mounting holes, and in described two ultrasonic transducer mounting holes, ultrasonic transducer is installed all, the flow tube core is installed in described flowtube, its main points are: be equipped with transducer Teflon coating on described two ultrasonic transducer lower surfaces, be provided with first reflector plate at described flowtube in-core, second reflector plate and the 3rd reflector plate are at described first reflector plate, be equipped with reflector plate Teflon coating on the reflecting surface of second reflector plate and the 3rd reflector plate.
Adopt above structure and since the Teflon coating not viscosity be that nearly all material does not demonstrate well not adhesion property with Teflon bonding, the very thin film of filming yet.Therefore will on ultrasonic transducer lower surface, first reflector plate, second reflector plate and the 3rd reflector plate, be equipped with one deck Teflon coating, thereby well avoid the fouling of these vitals, increase the reliability of measurement data.
The centerline hole of described two the ultrasonic transducer mounting holes all tube hub line with described flowtube is vertical, on described flow tube core, have two the flow tube core holes corresponding with described two ultrasonic transducer mounting holes, described first reflector plate and second reflector plate lay respectively at described two flow tube core holes under, this first reflector plate and second reflector plate are fixed on the described flowtube in-core wall, and the unilateral prolongation of this first reflector plate and second reflector plate intersects and is " V " font, is fixed with the 3rd reflector plate on the flowtube in-core wall in the middle of described two flow tube core holes.All the tube hub line with described flowtube is vertical for the centerline hole of two ultrasonic transducer mounting holes of design in the above structure, so the signal that sends of ultrasonic transducer is " W " font by first reflector plate, second reflector plate and the 3rd reflector plate reflection back signal wire, and is so reasonable in design and measure more accurate.
Described flow tube core aperture screw and described flowtube are fixed, and between described flowtube and flow tube core O-ring seal are housed.When in the flowtube that the utility model is installed to sonac, in two O-ring seal mounting grooves, O-ring seal is installed, thereby is reached good sealing effectiveness.
Effect of the present utility model: the utility model novelty simple in structure by handling carrying out good antiscale property on the vitals in the ultrasonic flow sensor, promptly increases one deck Teflon coating, thereby improves serviceable life of the present utility model and measuring accuracy.
