The vortex flow meter capable of being mounted and dismounted on-line has the advantages of avoiding various practical problems that gas and flow need to be cut off when damaged sensing parts of a common vortex flow meter are replaced and the like; and the structure is simple, the mounting is convenient, the reliability is high, and the practical value is high.
Description
Technical field
The utility model belongs to the flow measurement instrument field, and particularly a kind of vortex shedding flow meter that can online dismounting is used to measure the flow of various liquid, gas.
Background technology
Vortex shedding flow meter is based on the Karman vortex street principle, and promptly fluid produces whirlpool behind eddy generator, and the flow velocity of whirlpool frequency and pipeline inner fluid is proportional.Fluid is through behind the eddy generator, changes the whirlpool frequency that can record fluid from the fluid differential pressure of vortex arising, and then the flow of measurable flow body.Vortex shedding flow meter can be measured liquid, gas flow.The fluid differential pressure of test fluid vortex arising changes; Can sensor be installed in eddy generator rear side in the pipeline; The whirlpool of fluid can make the sensor mechanical hook-up produce small motion, and sensing part will detect motor message and convert electric signal to, thereby realizes the measurement of flow.Because there are various operating modes such as high temperature, high pressure, corrosion in processing medium, the sensing part that contacts with measured medium usually is impaired easily.And common vortex shedding flow meter must stop the supple of gas or steam, arrhea when the impaired needs of sensing part are changed, and could change sensing part.Thereby the continuous production that influence is produced causes a large amount of economic losses.For addressing this problem, we propose the vortex shedding flow meter that this can online dismounting.
Summary of the invention
The purpose of the utility model provides a kind of vortex shedding flow meter that can online dismounting, has solved high temperature, high pressure, the detection of inflammable and explosive medium and the problem of on-line replacing.Simple in structure, easy for installation, reliability is high.For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises detector tube 1, eddy generator 2, radiating permanent seat 5, connecting pipe 15, stress conductive bar 3, sensor probe 6.Eddy generator 2 is installed in detector tube 1 inner chamber, radiating permanent seat 5 is installed on the detector tube outer wall, connecting pipe 15 is installed on the radiating permanent seat 5, sensor probe 6 is inserted in the connecting pipe 15, on the inner detector tube tube wall of radiating permanent seat, is fitted with stress conductive bar 3.
Sensor probe is rod-like structure; The head of sensor probe is coniform; The end of sensor probe is connected with flow instrumentation through lead; Sensor top nose-circle cone is smoothly transitted into coniform by right cylinder, the terminal conical recess interference fit of this cone shape probe and stress conductive bar.The stress conductive bar is sent to sensor probe with the stressed size of eddy generator, to realize the measurement of flow.
The advantage of the utility model is, avoided common vortex shedding flow meter in that sensing part is impaired when needing to change, various practical problemss such as must stop the supple of gas or steam, arrhea; And have simple in structure, easy for installation, reliability is high, and very strong practical value is arranged.
