Description
Technical field
The utility model relates to flow measurement field, specifically provides a kind of current transformer.
Background technology
In existing fluid-duct-system, when fluid flows through shape tube, corner, irregular pipeline, violent change can be there is in fluidised form, vibrations, noise, change in flow, cavitation erosion can be produced, erosive wear is caused to pipeline, and the equipment such as intrasystem pump, valve are damaged, especially in rate-of flow measuring process, there will be the insufficient development of fluid media (medium), the situation such as cause flow metering to fluctuate maybe cannot to measure greatly.
And how to solve the problem, become people's problem demanding prompt solution.
Utility model content
Given this, the purpose of this utility model is to provide a kind of current transformer, through shape tube, corner and irregular pipeline, causes erosive wear to pipeline at least to solve fluid in the past, and injury equipment, causes flow metering to fluctuate large, the problem such as cannot to measure.
The technical scheme that the utility model provides, is specially, and a kind of current transformer is installed on fluid line inside, it is characterized in that, described current transformer comprises:
Central shaft 1;
Unsteady flow blade 2, its periphery along described central shaft 1 is spaced apart, and one end of described unsteady flow blade 2 is fixedly connected with described central shaft 1, the other end connects with the sidewall 4 of described fluid line, forms fluid passage 3 between unsteady flow blade 2 adjacent one another are and the sidewall 4 of fluid line.
Preferably, described unsteady flow blade 2 is along the periphery uniform intervals distribution of described central shaft 1.
Further preferably, described unsteady flow blade 2 comprises:
Support bar 21;
Blade 22, its entirety is triangular in shape, and described blade 22 side is fixedly connected with described support bar 21, and the base of described blade 22 is indent arc.
Further preferably, described unsteady flow blade 2 entirety is in similar triangle, and every bar side of described unsteady flow blade 2 is all curved, and described unsteady flow blade 2 increases progressively along described fluid line center gradually to pipe side wall direction width.
The current transformer that the utility model provides, be installed on the inside of fluid line, complete overall support by central shaft, form fluid passage by unsteady flow blade and fluid line sidewall simultaneously, the fluid in pipeline is flowed along the fluid passage formed, with alter trend and velocity flow profile, make flow velocity on cross section even, to reduce the erosive wear caused pipeline, and reduce the injury to equipment in pipeline, reduce the fluctuation of flow metering, to measure.
The advantages such as the current transformer that the utility model provides, has structure simple, reasonable in design, with low cost, easy to use, are conducive to the fluctuation reducing flow metering, the carrying out of convenient metering.

Embodiment
With specific embodiment, the utility model is further expalined below, but is not limited to protection domain of the present utility model.
Shape tube is flowed through in order to solve fluid in the past, when corner and irregular pipeline, what exist is large to the erosive wear of pipeline, cause equipment damage in pipeline, flow metering fluctuation is large, the problems such as metering cannot be realized, a kind of current transformer of the utility model, see Fig. 1, Fig. 2, this current transformer comprises central shaft 1, periphery along described central shaft 1 is intervally distributed with unsteady flow blade 2, and one end of described unsteady flow blade 2 is fixedly connected with described central shaft 1, the other end connects with the sidewall 4 of described fluid line, fluid passage 3 is formed between unsteady flow blade 2 adjacent one another are and the sidewall 4 of fluid line.
Alter can be moved towards and velocity flow profile in pipeline by the setting of this current transformer, make the flow velocity on cross section even, to reduce the erosive wear making twin conduit because flow is excessive, and to problems such as equipment injuries in pipeline.
See Fig. 3, in order to produce erosive wear to elbow when anti-fluid flows through elbow, in the front end of elbow, current transformer A is installed, and now, when fluid flows through elbow, need first through current transformer A, by the stop of the unsteady flow blade convection cell in current transformer A, force fluid to move in the fluid passage that the sidewall of unsteady flow blade and fluid line is formed, alter is moved towards and velocity flow profile in pipeline, to reduce the erosive wear to elbow.
See Fig. 4, before current transformer A is arranged on flow detecting element 5, the fully developed section of fluid media (medium) is shortened greatly, when current transformer A is not installed, the fully developed section of fluid will reach 20 ~ 30 times of distances of pipe diameter, and after being provided with current transformer A, fully developed section only only needs 1 ~ 3 times of distance of pipe diameter, greatly facilitate installation, the pipeline originally not possessing mounting condition is installed smoothly after application current transformer A.
Wherein, current transformer A and the connected mode between fluid line can adopt flange bolt to be connected, and the mode of welding also can be adopted directly to be welded on pipeline by current transformer A.
In addition, above-mentioned current transformer A can also be applied to the front and back end of the equipment such as water pump, plasticator, variable valve, plays proterctive equipment, the object of extension device turn(a)round.
In order to improve the unsteady flow effect of this current transformer, as the improvement of technical scheme, described unsteady flow blade 2 is along the periphery uniform intervals distribution of described central shaft 1.
Wherein, in above-mentioned current transformer, the structure of unsteady flow blade can be selected multiple, see the concrete structure that Fig. 1 is a kind of unsteady flow blade 2, comprising: support bar 21; Blade 22, its entirety is triangular in shape, and described blade 22 side is fixedly connected with described support bar 21, and the base of described blade 22 is indent arc.
See the concrete structure that Fig. 2 is another kind of unsteady flow blade 2, described unsteady flow blade 2 entirety is in similar triangle, and every bar side of described unsteady flow blade 2 is all curved, and described unsteady flow blade 2 increases progressively along described fluid line center gradually to pipe side wall direction width.
In above-mentioned two kinds of structures, the arc-shaped side design of unsteady flow blade, is all the flow velocity in order to better adjust fluid.
Embodiment of the present utility model carries out writing according to the form of going forward one by one, and highlight the difference of each embodiment, its similar portion can cross-reference.
