Abstract
The utility model discloses a metering equipment, making use of ultrasonic detection technology to meter liquid capacity or heat in the pipeline; the utility model is especially adapted for metering liquid flow capacity and heat in the pipeline with relatively bigger diameter. The technical proposal is that an insert type supersonic flow capacity and a calorimeter comprise two insert type energy converters and a converter (9); the two insert type energy converters are fixed together through a connecting piece (5) and become an entirety; the entirety is fixedly installed on a metered pipelines (8), and adopts battery to supply power to the meter. The utility model is provided with advantages as follows: two energy converters are fixed together, and probe spacing is fixed, irrelevant to the diameter of the pipeline to be metered; installation spacing occupation is small, which can arbitrarily select installation site, according to the industrial site environment, and has real meaning in industrial site. The energy converter can adopt two different ways to receive and dispatch supersonic sign, and metering precision is visibly increased, comparing with 'V' way. Two probes are also fixed together, and can be simultaneously inserted in the pipeline, which is simpler and faster to install and repair.
Description
Affiliated technical field:
The utility model belongs to acoustics, field of sensing technologies, utilizes ultrasonic detecting technology, and the metering outfit of fluid flow or heat is specially adapted to measure flow, heat than liquid in the big-diameter pipeline in the metering pipeline.
Background technology:
At present, plug-in type ultrasonic flow, calorimeter are used for flow, the heat of liquid in the measuring channel, its composition comprises converter and transducer two parts, transducer is formed and is comprised: base, ball valve, probe rod, transducer assemblies, seal, wafer etc., with two the cover transducers be installed in independently respectively tested pipeline on, finish the detection to fluid flow heat in the pipeline, having need not to stop production gets final product installation and maintenance, convenient and swift, steady operation and other merits.And the plug-in type ultrasonic flow meter that has has solved the problem that flow, calorimetric transducer probe bar recoil.For example, the applicant's Chinese patent " a kind of insert cartridge of ultrasonic flow meter ", patent No. 99251293.X.But still there are some defectives in existing in actual use plug-in type ultrasonic flow, calorimeter, at first, according to existing measuring method, two insert cartridges are installed in the both sides of tested pipeline respectively independently, the installing space of transducer is by the diameter decision of tested pipeline, caliber is big more, and mounting distance is big more; But in industry spot, the installing space of transducer is subjected to the restriction of site environment, sometimes can't satisfy the needs of mounting distance, for satisfying the mounting distance requirement, usually can only adopt " V " mode to install, but " V " mounting means, ultrasound wave need be through primary event in pipeline, energy loss is arranged, lowered measuring accuracy.Secondly, the energy consumption of existing plug-in type ultrasonic flowmeter converter is bigger, mounting distance between two transducers is far away, also increased energy consumption, therefore existing plug-in type ultrasonic flow meter, calorimeter can only adopt the power supply of 220V power supply, this just causes plug-in type ultrasonic flow, calorimeter can't be applied in the working environment that does not have the 220V power supply, and is very inconvenient.
The utility model content:
The utility model purpose provides a kind of plug-in type ultrasonic flow, calorimeter, two transducers are fixed together, the installation site is fixed, mounting distance and tested pipeline caliber size are irrelevant, easy for installation, the power consumption of converter and transducer is low, can use battery to be instrument power supply, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: plug-in type ultrasonic flow, calorimeter are made up of two cover insert cartridges and converter, and two cover insert cartridges are fixed together by web member, become as a whole, are fixedly mounted on the tested pipeline.
Can two cover insert cartridges be fixed on the tested pipeline by fixed underpan.The installation because two transducers are fixed together, the mounting distance of transducer shortens greatly, reduced energy consumption yet, therefore adopted battery can satisfy the energy consumption demand fully to plug-in type ultrasonic flow, calorimeter power supply, having solved the working site does not have the problem that the 220V power supply can not use converter.
Transducer is formed and comprised: base, ball valve, probe rod, web member, transducer assemblies, seal, wafer etc., wafer is positioned at the end that probe rod inserts tested pipeline.The length that the probe rod of two transducers inserts in the tested pipeline can be identical, also can be different.The wafer of two transducers can be arranged on the same plane parallel with tested pipeline, and is directly corresponding mutually, ultrasonic signal rectilinear propagation; Also can not be mutually directly corresponding, by the reflection of self reflecting surface on the probe rod, corresponding indirectly, the ultrasonic signal oblique line be propagated.
Transducer can adopt two kinds of different modes to receive and dispatch ultrasonic signal.A kind of mode is that two transducers are directly to sending out ultrasonic signal, the energy loss of avoiding indirect reference to cause.During work, an end transducer sends ultrasonic signal, and the transducer of the other end is received signal, and again by this transducers transmit ultrasonic waves signal, other end transducer receives.Another kind of mode is by the reflection supersonic wave of transducer own, and an end transducer sends ultrasonic signal, and other end transducer is received signal after self reflects, and again by this transducers transmit ultrasonic waves signal, through self reflection, other end transducer receives reflected signal.Though energy loss is also arranged, compared with " V " mounting means in the background technology, the installation site of transducer is near, ultrasonic propagation is apart from weak point, if inside pipe wall fouling, " V " mode can make ultrasound wave produce diffuse reflection, then do not worry the problem of fouling through the reflection of transducer own.So " V " mounting means energy loss is little relatively, the measuring accuracy height.
Adopt the utility model, two bases of transducer are fixed together with being connected the chassis respectively, and probe spacing is fixed, and irrelevant with caliber to be measured, it is little to take installing space; The rear end of two probe rods is fixed together with a web member, and two transducers have formed a fixing integral body.During installation, can select the installation site arbitrarily according to the industry spot environment, two probe rods can insert in the pipeline simultaneously, install, dismounting is more convenient, in industry spot realistic meaning arranged very.The utility model has not only kept existing plug-in type ultrasonic flow, calorimetric whole advantages, has overcome the defective of prior art simultaneously.Transducer can adopt two kinds of different modes to receive and dispatch ultrasonic signal, and " V " mode in the relative background technology of measuring accuracy is significantly increased.The energy-saving design of converter and two fixed transducer have all reduced energy consumption, can be applied to powered battery type instrument.In addition, when industry spot is installed,, needn't calculate mounting distance again, also needn't on pipeline, delimit the installation site, and two probes be fixed together also, can insert simultaneously in the pipeline, install, safeguard simple more, quick because transducer position is fixed.
