Abstract
The invention relates to a method for enabling fluid in an ultrasonic flowmeter to flow smoothly, a fluid metering device comprises a flow pipe, the fluid is buffered at the inflow end of the flow pipe, and then the fluid is divided into a plurality of streams for flowing into the body of the flow pipe. The invention further provides a structure, a diversion frame is arranged in the flow pipe, and a core plug and a flow guide parting strip in the diversion frame are used for re-guiding the fluid, thereby breaking the original disordered state and further entering into the ordered state. The structure is simple, and the accuracy of the ultrasonic flowmeter can be greatly improved.
Description
(1) technical field
The present invention relates to a kind of apparatus for metering fluids metering householder method and structure thereof more accurately of making.
(2) background technology
Therefore the information of rate of flow of fluid just can detect flow rate of fluid through the ultrasound wave that receives, thereby be converted into flow on just carrying when existing ultrasonic flow meter, ultrasound wave are propagated in flowing fluid.When measuring rate of flow of fluid, the flow state of fluid has very big influence to the measurement of flow velocity, but owing to pipeline is installed or the reason of fluid type; Like eddy current, bubble etc.; Fluid flow state is a disordered state, and is very not steady, and the accuracy of measuring is had very big influence.
(3) summary of the invention
In order to overcome deficiency of the prior art, the present invention provides a kind of method that can make the fluid smooth flow in the ultrasonic flow meter;
Of the present invention also have a purpose to provide a kind of ultrasonic flow meter that can use fluid smooth flow method.
The technical scheme that the present invention solves its technical matters is:
A kind of method that makes ultrasonic flow meter inner fluid smooth flow, described ultrasonic flow meter comprise the stream pipe, after the inflow end of stream pipe cushions fluid, fluid are divided in the body of some plume inflow pipes again.
Ultrasonic flow meter; Comprise the stream pipe; The inflow end of described stream pipe is provided with a shunting frame, and described shunting frame includes and flows into end and outflow end, and the coaxial tubulose that is provided with divides fluid in the middle of the described shunting frame; And described minute fluid radially is provided with some water conservancy diversion parting beads flowing into the stifled plug that is provided with the ball-crown body shape in end place between minute fluid and shunting frame.
Divide the two ends of fluid all to be positioned at the shunting frame, described water conservancy diversion parting bead is flowing into end for meeting the inclined-plane to current, and the water conservancy diversion parting bead is the inclined-plane of current dorsad at outflow end, and described water conservancy diversion parting bead equidistantly distributes.
Reason owing to pipeline installation or fluid type; Flowing fluid is inhomogeneous unordered in the stream pipe; Produce vortex, bubble etc. like meeting; Promptly be not the smooth flow under the perfect condition, and apparatus for metering fluids need to get rid of these labile factors and makes measurement reach maximum accuracy when measuring.Method is earlier fluid to be cushioned, and then is divided into the body of shallow bid stream inflow pipe.Inflow end at the stream pipe is provided with a shunting frame, and fluid flows into from flowing into end, and the fluid that is positioned at periphery is not met barrier; Be divided into by the water conservancy diversion parting bead and flow into correspondingly passage respectively after some strand; The fluid at middle part is met the sphere barrier, is cushioned, and is guided the passage that flows between the water conservancy diversion parting bead; Promptly also be divided into some strands, flow out from outflow end then.Above-mentioned by sphere guiding or water conservancy diversion parting bead guided procedure in, original state of part vortex or bubble etc. is broken, original disordered state is by guiding again, thereby gets into order state.
Beneficial effect of the present invention is: the invention reside in a kind of method that provides, promptly make fluid be in the state of smooth flow through buffering and the method that is divided into shallow bid.The present invention can improve the accuracy of ultrasonic flow meter.
The present invention also is to provide a kind of structure, and a shunting frame is set in the stream pipe, and plug and water conservancy diversion parting bead in the shunting frame are guided fluid again, break original disordered state, thereby get into order state.The present invention is simple in structure, can improve the accuracy of ultrasonic flow meter greatly.
(4) description of drawings
Fig. 1 is a sectional structure synoptic diagram of the present invention;
Fig. 2 is the perspective view of shunting frame.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
Like Fig. 1, shown in 2; A kind of ultrasonic flow meter that makes the fluid smooth flow comprises stream pipe 1, uses a kind of method that makes ultrasonic flow meter inner fluid smooth flow; After the inflow end of stream pipe 1 cushions fluid, again fluid is divided in the body of some plume inflow pipes.The inflow end of stream pipe 1 is provided with a shunting frame 2, and shunting frame 2 also is a tubulose, and is provided with O-ring seal 3 between shunting frame 2 and the stream pipe.Shunting frame 2 includes and flows into end and outflow end; The coaxial tubulose that is provided with divides fluid 6 in the middle of the shunting frame; And divide fluid 6 flowing into the stifled plug 4 that is provided with the ball-crown body shape in end place; The diameter of the bottom surface of plug 4 is identical with the diameter that divides fluid, between minute fluid and shunting frame, radially is provided with the water conservancy diversion parting bead 5 of some equidistant distributions.Divide the length of the length of fluid less than the shunting frame, promptly divide the two ends of fluid all to be positioned at the shunting frame, the water conservancy diversion parting bead is flowing into end for meeting the inclined-plane to current, and the water conservancy diversion parting bead is the inclined-plane of current dorsad at outflow end.
Reason owing to pipeline installation or fluid type; Flowing fluid is inhomogeneous unordered in the stream pipe; Produce vortex, bubble etc. like meeting; Promptly be not the smooth flow under the perfect condition, and apparatus for metering fluids need to get rid of these labile factors and makes measurement reach maximum accuracy when measuring.
Inflow end at stream pipe 1 is provided with a shunting frame 2, and fluid flows into from flowing into end, and the fluid that is positioned at periphery is not met barrier; Be divided into by water conservancy diversion parting bead 5 and flow into correspondingly passage respectively after some strand; The fluid at middle part is met the sphere barrier, is cushioned, and is guided the passage that flows between the water conservancy diversion parting bead; Promptly also be divided into some strands, flow out from outflow end then.Be that said structure has used elder generation that fluid is cushioned, be divided into the method for the body of some plume inflow pipes then.Above-mentioned by sphere guiding or water conservancy diversion parting bead guided procedure in, original state of part vortex or bubble etc. is broken, original disordered state is by guiding again, thereby gets into order state.
The present invention makes fluid be in the state of smooth flow through the method for buffering and guiding again, and structural approach is all very simple, can effectively improve the accuracy of ultrasonic flow meter.
