Abstract
The present invention relates to an eddy-proofing water delivery rectifying equipment, consisting of water delivery pipe, transition pipe, rectifying diaphragm plate, intake pipe and non-return valve plate. It is characterized by that all the pipes are flange-connected between them, the transition pipe is made into the form of horn, the diameter ratio of the intake pipe and water delivery pipe is kept at 1.4 to 2.4, the interior of the intake pipe is equipped with a group of rectifying diaphragm plates with cellular section, and a non-return valve plate is flange-connected on the underside of the rectifying diaphragm plates through intake pipe. Said equipment can effectively reduce eddy quantity in the pipeline to maximum, and can raise flow quantity by about 10% under the condition of identical water delivery pipe and differential head, and has no need of increasing capital cost.
Description
The present invention relates to a kind of eddy-current prevention water-deliverying rectifying device, this device is specially adapted to various types of city tap-water pipeline systems.
As everyone knows, always there is vortex to produce in the pipeline ingress, pond of water delivery (or oil transportation) pipe-line system, and the closer to the vortex core, flow velocity is big more, static pressure is more little, causes the amount of dissolving in of vapour to strengthen, because the depression in vortex core district also makes the air mixed volume strengthen, so particularly the accumulation of a large amount of air is just arranged, its effective water delivery cross section is reduced and directly influence flow at pipeline absolute altitude value larger part (being the hydraulic pressure lower).Experiment shows that working as the volume of air of being gathered reaches and will make when occupying a certain section blank pipe that the flow resistance of water heightens in the pipeline, and flow subtracts greatly, and this situation is mobile unfavorable especially to water in the siphon aqueduct of no additionaling power, even can make the flow stoppage of water.This problem is long-standing, but relevant professional workforce often ignores its adverse effect.Existing on the other hand siphon aqueduct inlet valve (or claiming pump) does not have rectified action.Existing inlet valve structure generally is exactly an one-way valve, traditional one-way valve not only structure is simple especially, and easy to implement reliable with use, and for example valve body itself is set as the slotted hole with two different-diameters, one end of the large diameter hole steel ball of packing into withstands on the top of small diameter bore with spring with it.If this valve body is inserted in pipe-line system, only this steel ball could be backed down during greater than major diameter one end pipe fluid pressure at the pipe fluid pressure of minor diameter one end, fluid is entered in the major diameter one end pipeline.But it is apparent that this structure and be not suitable for the big and low water delivery pipeline system of pressure of diameter, because be subjected to the restriction of steel ball size or weight.
The objective of the invention is to propose a kind of eddy-current prevention water-deliverying rectifying device, in this device is combined in inlet valve, to satisfy the needs of siphon aqueduct, this device also makes the water in the pipeline can reduce the eddy current amount to greatest extent under identical flow, thereby the minimizing loss of head, the flow of water in the raising pipeline.
The concrete technical measures of implementing above-mentioned purpose of the present invention and taking are as described below: rectifying device mainly is made up of conduit pipe, transition tube, Partition for realigning water flow, intake pipe and check valve sheet, wherein is set as flange between pipe and connects; Its tapering of transition tube flare is 6 to 19 °; Intake pipe keeps 1.4 to 2.4 with the diameter ratio of conduit pipe; One group of cross section of configuration is cellular Partition for realigning water flow in the intake pipe, and wherein honeycomb is set as polygonal, promptly can be triangle or quadrilateral, dividing plate leading edge rounding, and trailing edge is sharp, dividing plate is equivalent to 0.05 to 0.1 of water delivery caliber at interval; Fix a check valve sheet at the Partition for realigning water flow downside by the intake pipe flange, on this plate, be laid with a plurality of one-way valves, and each one-way valve constitutes by a slotted hole in the valve body and a steel ball, the through flow hole two ends rounding on the check valve sheet wherein, its aperture is slightly less than diameter of the steel ball, and to make the valve body flow-in hole that contacts with the steel ball driving fit be concentric with respect to through flow hole on the plate.
Now an embodiment of the eddy-current prevention water-deliverying rectifying device that in conjunction with the accompanying drawings the present invention is proposed is further described.Wherein:
Fig. 1 represents a longitudinal cross-section schematic representation of rectifying device of the present invention.
Fig. 2 represents the I-I line cross sectional representation by Fig. 1.
As shown in Figure 1, rectifying device of the present invention is made up of five parts, i.e. conduit pipe 1, transition tube 2, Partition for realigning water flow 4, intake pipe 5 and be provided with the plate of a plurality of one-way valves 3, obvious this structure and be suitable for inlet valve as the siphon aqueduct.When making steel ball and the driving fit of valve body flow-in hole by the static pressure of water from the peak of aqueduct when pipeline is poured water (eliminating gas), steel ball is isolated with the water on top and the water in pond, in case aqueduct is opened at the water outlet pipe valve of lower, the water in the pond is just pushed steel ball cellular Partition for realigning water flow 4 in through flow hole and the intake pipe 5 and form flowing of water in the aqueduct on the flow-in hole of one-way valve, plate open.When the bottom surface in pond or its subsurface side are provided with outlet pipe, just do not need one-way valve and valve plate, it can be removed, then fixed water inlet pipe 5 promptly forms the aqueduct through over commutation to the outlet pipe of pond.It is not adaptive to should be noted that Partition for realigning water flow 4 is located in the intake pipe 5, promptly tightly loose but also want positioning and fixing.
By Partition for realigning water flow honeycomb shape shown in Figure 2 is to be set as triangle, can certainly be set as other polygonals.
Practice shows, because rectifying device of the present invention can make the eddy current amount be reduced at utmost effectively, it is about 10% to improve flow under the same aqueduct and the same head discrepancy in elevation, and need not to increase the capital construction cost.And this device has characteristics such as simple in structure, easy for installation, economic and reliable and easy operating.
