Description of drawings
Fig. 1 is the structure cut-open view of the vortex flow sensor of the utility model.
Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing the utility model:
With reference to shown in Figure 1; The vortex flow sensor of present embodiment comprises Venturi tube 1; Spigot 2 has been installed in the inflow entrance of Venturi tube 1; Despinner 6 is installed in the flow export of Venturi tube 1; Upside is equipped with the piezoeletric quartz sensor 3 of the frequency signal that is used to monitor the precession of fluid whirlpool in the throat of the expansion segment of Venturi tube 1, and the output terminal of piezoeletric quartz sensor 3 links to each other with an input end of the flow integrator 4 that is installed in Venturi tube 1 top, and throat's inner underside of the expansion segment of Venturi tube 1 is equipped with pressure transducer 7; The output terminal of pressure transducer 7 links to each other with another input end of flow integrator 4; Upside is equipped with temperature sensor 5 in the expansion segment of Venturi tube 1, and temperature sensor 5 is positioned at the right side of piezoeletric quartz sensor 3, and the output terminal of this temperature sensor 5 links to each other with the 3rd input end of flow integrator 4.For the ease of manual detection; Have the manual detection mouth 8 with its perforation on the expansion segment of Venturi tube 1, manual detection mouth 8 places are provided with sealing-plug 9, when needs carry out manual detection; Remove sealing-plug 9; Detecting instrument is inserted Venturi tubes 1 from manual detection mouth 8 gets final product, to be detected finish fetch detecting instrument after, again sealing-plug 9 is loaded onto.
During use, the flange through Venturi tube 1 right ends is connected to the vortex flow sensor string on the pipeline, when when axial fluid gets into the vortex flow sensor; Playing the whirlpool device 2 times, fluid is forced the center line rotation around Venturi tube 1, produces eddy-currents; Eddy-currents precession in Venturi tube 1 after the unexpected throttling of contraction section of arrival Venturi tube 1, quickens eddy-currents; When passing through the diffuser of Venturi tube 1, the whirlpool center is along a conical helix precession.At this moment; After front end circuit amplification, filtering, shaping, convert the pulse signal that two-way is directly proportional with flow velocity into by piezoeletric quartz sensor 3 detected eddy-currents precession frequency signals; Warp wherein treatment circuit carries out the comparison and the judgement of phase place; And send into flow integrator 4 with temperature sensor 5 detected temperature signals, pressure transducer 7 detected pressure signals behind the rejecting extraneous interference signal and carry out calculation process, directly be shown in parameters such as the volumetric flow rate of fluid, total amount, pressure, temperature on the LCD screen of flow integrator 4 by flow integrator 4.Thereby make the vortex flow sensor of present embodiment can not only carry out flow detection, can also carry out parameter detecting such as pressure, temperature.
Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineering technical personnel in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
