Abstract
The utility model discloses a take reflection column type supersound flow sensor of barretter, including metal pipeline, advance, return water reflection post, advance, return water transducer and transducer clamp plate, be equipped with temperature sensor mounting hole, its characterized in that on the metal pipeline wall in the outside of return water reflection post: metal pipeline intake reflection post and transducer to the return water of intaking relatively and reflect between post and the return water transducer one section and for the thin pipe section that contracts, be equipped with the plastics barretter in the thin pipe section that contracts, the plastics barretter is installed in the thin pipe section that contracts with interference fit's mode through close adhesive layer. This take reflection column type supersound flow sensor of barretter is because the metal pipeline internal diameter between two reflection posts reduces to on building in in dwindling the pipeline section inner wall smoothness high, also be difficult to adhere to the plastics barretter of silt or scale deposit down in the long -time operation of high temperature, so stablize in the flow field under the high temperature, the pipe diameter is unchangeable, measurement accuracy is high, long service life.
Description
Technical field
The utility model relates to a kind of improvement of reflecting pillar ultrasonic flow transducer, specifically a kind of reflection pillar ultrasonic flow transducer with barretter.Be applicable to reflection pillar ultrasonic heat meter, by increasing barretter between two reflection pillar in metallic conduit, add the stability of flow, improve measuring accuracy.
Background technology
Along with the popularization that national heat metering is reformed, ultrasonic calorimeter obtains large-area promotion and application with its mechanical parts, the advantage such as not fragile.Especially along with the requirement of country to the long life in recent years, there is a lot of ultrasonic calorimeter flow sensor with reflection pillar replacement plastic stent supporting reflex face on the market, its structure comprises metallic conduit, water inlet reflection pillar, backwater reflection pillar, water inlet transducer, backwater transducer and transducer pressing plate, the two ends of metallic conduit are provided with threaded connector, water inlet reflection pillar and water inlet transducer are located at the one end in metallic conduit, and backwater reflection pillar and backwater transducer are located at the other end in metallic conduit; Known by retrieving, what have also connects air deflector in the outside of water inlet reflection pillar, between water inlet reflection pillar and backwater reflection pillar, be provided with mozzle, leave gap between the outer wall of mozzle and the inwall of metallic conduit, the inner diameter of metallic conduit is consistent vertically.The deficiency of this ultrasonic calorimeter flow sensor is: the material due to metallic conduit is copper or stainless steel, it is smooth that inside pipe wall is not easy processing, the direct medium contact with flowing through calorimeter of inner-walls of duct between two reflection pillar, because inner-walls of duct is coarse, so easily adhere to mud or spot, especially for a long time after hot operation, more easily cause inner-walls of duct fouling, inner-walls of duct is caused to become more coarse, change " caliber ", namely change the basic parameter value of flow rate calculation, cause metering inaccurate; Even if installed mozzle, but owing to leaving gap, still fouling in its gap between the outer wall of mozzle and the inwall of metallic conduit, fouling is finally deposited at the two ends of mozzle, still changes " caliber ", also causes metering inaccurate.
Summary of the invention
The reflection pillar ultrasonic flow transducer that the purpose of this utility model is to provide a kind of and can prevents metal pipe internal wall fouling and caliber from diminishing, improve measuring accuracy, be applicable to the band barretter of ultrasonic calorimeter metering.
In order to reach above object, the technical scheme that the utility model adopts is: the reflection pillar ultrasonic flow transducer of this band barretter, comprise metallic conduit, water inlet reflection pillar, backwater reflection pillar, water inlet transducer, backwater transducer and transducer pressing plate, the two ends of metallic conduit are provided with threaded connector, water inlet reflection pillar and water inlet transducer are located at the one end in metallic conduit, backwater reflection pillar and backwater transducer are located at the other end in metallic conduit, transducer pressing plate is arranged on the outer end into water transducer and backwater transducer, the metallic conduit wall in the outside of backwater reflection pillar is provided with temperature sensor fixing hole, it is characterized in that: relatively intake reflection pillar and water inlet transducer of described metallic conduit is shrinking pipe section between backwater reflection pillar and backwater transducer section, plastics barretter is provided with in shrinking pipe section, the overall diameter of plastics barretter is consistent with the interior diameter of shrinking pipe section, be arranged in an interference fit in shrinking pipe section by sealant layer.
The utility model is also implemented by following measure: the internal diameter of described shrinking pipe section is than the internal diameter indentation 1.5mm of metallic conduit; Correspondingly, the wall thickness of described plastics barretter is 2mm, is MODIFIED PP S plastic tube or PPO plastic tube.
The inwall two ends of described shrinking pipe section are hydraucone; The water side of shrinking pipe section is provided with baffle ring, and the inwall of baffle ring and shrinking pipe section is processed as one.
The beneficial effects of the utility model are: the reflection pillar ultrasonic flow transducer of this band barretter, because the metallic conduit internal diameter between two reflection pillar reduces, and reducing in pipeline section the plastics barretter that smoothness of inner wall on build-in is high, be also not easy to adhere to mud or fouling under high temperature long-play, so high temperature Fluid field is stable, caliber is constant, measuring accuracy is high, long service life.
