The reflection surface of each reflection board is a mirror surface which is manufactured by the accurate grinding process and then welded in the flowmeter basic meter cavity by lasers. The invention solves the technical problems of large metering error, heavy metal pollution and short service life in the prior art.
Description
Technical field the invention belongs to heat energy table technical field, relates to small-bore ultrasonic flow meter base table of a kind of powered battery fluxoid and preparation method thereof.
The flowmeter base table that background technology is traditional is the straight tube-like structure, is formed by the casting of brass material, and is inner for reflecting plate being installed, the signal of reflection piezoelectric transducer, mounting bracket in the flowmeter pipeline usually.The base table of this structure has not only influenced the flux of liquid, formation turbulent flow, ultrasound wave effective sound path in liquid shortens easily simultaneously, causes the big problem of error in dipping, but also has the problem of heavy metal pollution; Because the radiator of using in domestic a lot of user families is that the cast iron founding is made mostly, impurity is more, and is bigger to the wearing and tearing of the reflecting plate in the heat energy table base table, influences its serviceable life.
Summary of the invention the objective of the invention is to solve that prior art exists that error in dipping is big, heavy metal pollution, serviceable life short technical matters, provide small-bore ultrasonic flow meter base table of a kind of powered battery fluxoid and preparation method thereof, to overcome the deficiencies in the prior art.
To achieve these goals, the small-bore ultrasonic flow meter base table of powered battery fluxoid of the present invention, it comprises the arcuation body of stainless steel casting and the straight tube-like entery and delivery port at two ends thereof, be respectively equipped with the ultrasound piezoelectric transducer above arcuation body and the straight tube-like entery and delivery port binding site die cavity is installed, be respectively equipped with the stainless steel mirror reflecting plate below arcuation body and the straight tube-like entery and delivery port binding site, the stainless steel mirror reflecting plate is 45 ° of angle settings, is provided with gland above the described ultrasound piezoelectric transducer installation die cavity.
In order to improve the smoothness of base table inner chamber, the preparation method of the small-bore ultrasonic flow meter base table of powered battery fluxoid of the present invention, its main points casting adds man-hour, earlier ceramic core is placed in the corresponding mould, and then with the moulding of stainless steel water one-step casting, the ceramic core after the shaping in the broken again base table chamber, guarantee the smoothness of cavity wall in the base table, the reflecting surface of reflecting plate is a minute surface, adopts fine grinding technology to make, and adopts laser bonding then on flowmeter base table inner chamber.
The present invention's beneficial effect compared with prior art is:
1, traditional flowmeter base table chamber is a straight tube-like, inner for the signal of baffle reflection piezoelectric transducer is installed, the reflecting plate support is installed in the flowmeter tube chamber usually, influenced the flux of flow, form turbulent flow simultaneously in inner chamber easily, the effective sound path of sound wave in liquid shortens.Ultrasonic flow meter base table of the present invention is installed reflecting plate and is partly adopted arcuate structure, reflecting plate is welded on the arcuate structure place, be 45 degree angles with center line, no support, do not have turbulent flow and produce fluid flow fluxoid, low pressure loss, effectively raise the measurement sound path of ultrasound wave in liquid, improved measuring accuracy.
2, traditional flowmeter base table is a straight tube-like, and inside is adopted process for machining finishing usually, guarantees the smoothness of inside pipe wall, and therefore, operation easier is big.Ultrasonic flow meter base table of the present invention is owing to be the inner machine work difficulty of arcuate structure, employing ceramic core precision casting process, and broken ceramic core after the moulding guarantees the smoothness of inner-walls of duct, and is therefore, simple to operate.
3, the reflecting surface of the reflecting plate in the ultrasonic flow meter base table of the present invention is a minute surface, adopts fine grinding technology to make, and adopts laser welding technology to be welded on the flowmeter base table then, and minute surface is indeformable.
4, adopt stainless steel to make flowmeter base table chamber, with respect to the basis brass material, heavy metal free pollutes.
When 5, using, flowmeter adopts the side mounting means, and reflecting plate is perpendicular to surface level, and during no flow, impurity is not easy to be deposited on the reflecting plate minute surface in the liquid, has improved the serviceable life of flowmeter.
6, fluxoid design, no support in the circulation tube chamber, impurity is not easy to stop up base table in the liquid, has improved flowmeter resistance to overturning and serviceable life.
7, the ultrasound piezoelectric transducer is installed the efficient transducer of ultrasound piezoelectric transducer employing low-power consumption of equipment in an actor's rendering of an operatic tune, the piezoelectric element of ultrasonic flow meter transducer is a thin rounded flakes, along thickness vibration, the thin slice diameter surpasses 12 times of its thickness, to guarantee the directivity of vibration, adopt precision die to make transducer enclosure, guarantee that measuring accuracy is not subjected to temperature and pressure variable effect.
Appended drawings is a structural representation of the present invention.
