Abstract
The utility model provides a swirl flowmeter's a spigot, including dabber and blade, the blade is the spiral setting around the dabber, the vane thickness is outwards crescent from the dabber, a transversal ring -type of personally submitting of blade. A swirl flowmeter's a spigot, through improving playing a spigot blade, the vane thickness is outwards crescent from the dabber, the transversal ring -type of personally submitting of blade, the blade intensity after the improvement is higher, also can not reduce the fluid volume through the flowmeter.
Description
Technical field
The utility model belongs to field of flow detection, particularly a kind of pipe cyclone of swirl flowmeter.
Background technology
Swirl flowmeter is widely used in the industries such as oil, chemical industry, electric power, metallurgy, city air feed and measures various gas flow, is the first-selected product of current oil field and the metering of city gas transmission & distribution and Trade Measures.Swirl flowmeter is a kind of fluid oscillating flowmeter, utilizes vortex precession phenomenon to carry out flow measurement, and pipe cyclone is the mechanism producing whirlpool precession phenomenon, and it is fixed on housing shrinkage section front end, forces fluid to produce strong bumpy flow.
Pipe cyclone comprises blade and mandrel, blade shroud is arranged to spirality around mandrel, mandrel is positioned on the central axis of pipe cyclone, the leaf cross-section arranged around mandrel is rectangular, tradition pipe cyclone is adding man-hour to make the fluid volume increase passed through in pipe cyclone, take and pipe cyclone blade is done thin, the method that mandrel is run business into particular one, this method can increase the fluid volume passed through to a certain extent, but this method can make the intensity of pipe cyclone greatly reduce, long-term for easily making pipe cyclone damage during large discharge, thus affect the serviceable life of flowmeter.
Summary of the invention
The purpose of this utility model is to provide a kind of pipe cyclone of swirl flowmeter, and intensity is high, long service life.
For achieving the above object, the utility model is by the following technical solutions:
A pipe cyclone for swirl flowmeter, comprise mandrel and blade, blade shroud is arranged twist around mandrel, and described vane thickness outwards increases gradually from mandrel, and the xsect of described blade is in fan ring-type.
Preferably, described blade is at least three, arranges around mandrel Central Symmetry.
The pipe cyclone of a kind of swirl flowmeter described in the utility model, by improving pipe cyclone blade, vane thickness outwards increases gradually from mandrel, and the xsect of blade is in fan ring-type, blade strength after improvement is higher, also can not be reduced by the fluid volume of flowmeter.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the pipe cyclone of swirl flowmeter in prior art;
Fig. 2 is the cross sectional representation of pipe cyclone described in the utility model.
Embodiment
Fig. 1 is the cross sectional representation of the pipe cyclone of swirl flowmeter in prior art; As shown in Figure 1, pipe cyclone comprises blade 2 and mandrel 1, and blade 2 is arranged to spirality around mandrel, mandrel 1 is positioned on the central axis of pipe cyclone, the blade 2 arranged around mandrel 1 stretches out from mandrel, and the thickness of blade 2 remains unchanged, and the xsect of blade 2 is rectangular.Pipe cyclone blade, adding man-hour to make the fluid volume increase passed through in pipe cyclone, doing thin, but can reduce blade strength like this, fragile blade by pipe cyclone of the prior art usually.Fig. 2 is the cross sectional representation of pipe cyclone described in the utility model.A kind of pipe cyclone improvements over the prior art point for swirl flowmeter described in the utility model is that blade 2 is when mandrel 1 stretches out, the thickness of blade 2 increases gradually, the xsect of blade 2 is in fan ring-type, and described blade 2 is at least three, arranges around mandrel Central Symmetry.Due to swirl flowmeter operationally, the blade 2 of pipe cyclone is stressed relatively little near the part of mandrel 1, part away from mandrel 1 is stressed relatively large, therefore the thickness of blade 2 is arranged to outwards strengthen gradually from mandrel 1, but the area of blade 2 xsect is still identical with before improvement, blade 2 after improvement can under the prerequisite not reducing the fluid volume that flowmeter passes through intensity higher, longer service life.
Claims (2)
1. a pipe cyclone for swirl flowmeter, comprise mandrel and blade, blade shroud is arranged twist around mandrel, it is characterized in that, described vane thickness outwards increases gradually from mandrel, and the xsect of described blade is in fan ring-type.
2. the pipe cyclone of a kind of swirl flowmeter as claimed in claim 1, is characterized in that, described blade is at least three, arranges around mandrel Central Symmetry.
