Abstract
The utility model relates to a kind of drag reduction flange, comprise land and lower land, jacket pipe is connected between two lands, the inner chamber of jacket pipe communicates with the endoporus of two lands, electrolysis ring is fixedly installed in described jacket pipe inner chamber, described electrolysis ring is positioned at the transition layer region of jacket pipe inner chamber, and the wire of described electrolysis ring stretches out two-dimentional conduit and is connected with power supply.By being arranged on the electrolysis ring in jacket pipe transition layer, the bubble that electrolysis ring is produced directly produces in transition layer, liquid is when chuck Bottomhole pressure, the interaction in transition layer of micro gas-bubble and turbulent flow, suppress turbulence pulsation, realize turbulent flow drag reduction, reduce the surface friction drag of jacket pipe course of conveying, also can reduce to enter surface friction drag suffered in subsequent pipeline simultaneously, improve drag reducing efficiency, reduce unnecessary waste, under the effect under the tolerance of same micro gas-bubble, improve liquid speed as much as possible.
Description
Technical field
The utility model relates to a kind of drag reduction flange.
Background technique
In industrial pipeline, flange, due to easy to use, can bear larger pressure, therefore uses very extensive; In present Cemented filling, the resistance of pipeline and conveying material is very large, and traditional flange also can only play a connection function to pipeline, does not play any effect for pipeline drag reduction.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of drag reduction flange, solves conventional flange can not carry out drag reduction in conveying defect to institute's connecting tube.
The utility model solves the technological scheme that its technical problem adopts: a kind of drag reduction flange, comprise land and lower land, jacket pipe is connected between two lands, the inner chamber of described jacket pipe communicates with the endoporus of two lands, electrolysis ring is fixedly installed in described jacket pipe inner chamber, described electrolysis ring is positioned at the transition layer region of jacket pipe inner chamber, and the wire of described electrolysis ring stretches out jacket pipe and is connected with power supply.
Further, jacket pipe is provided with insulating plug, described wire is connected with power supply through insulating plug.
Further, described jacket pipe is bend pipe.
Further, described electrolysis ring is fixed on through baffle plate in the transition layer region in jacket pipe.
The beneficial effects of the utility model are: by being arranged on the electrolysis ring in jacket pipe transition layer, the bubble that electrolysis ring is produced directly produces in transition layer, liquid is when chuck Bottomhole pressure, the interaction in transition layer of micro gas-bubble and turbulent flow, suppress turbulence pulsation, realize turbulent flow drag reduction, reduce the surface friction drag of jacket pipe course of conveying, also can reduce to enter surface friction drag suffered in subsequent pipeline simultaneously, improve drag reducing efficiency, reduce unnecessary waste, under the effect under the tolerance of same micro gas-bubble, improve liquid speed as much as possible.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of jacket flange;
Fig. 2 be in Fig. 1 A-A to sectional view;
The schematic diagram of Fig. 3 to be jacket pipe be forniciform jacket flange;
Wherein: 1, upper land, 2, lower land, 3, jacket pipe, 4, electrolysis ring, 5, baffle plate, 6, insulating plug.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Fig. 1 Fig. 2, a kind of drag reduction flange, comprise land 1 and lower land 2, jacket pipe 3 is connected between two lands, the inner chamber of jacket pipe 3 communicates with the endoporus of two lands, in jacket pipe 3 inner chamber, be fixedly installed electrolysis ring 4, electrolysis ring 4 is fixed on through baffle plate 5 in the transition layer region in jacket pipe 3.Electrolysis ring 4 is positioned at the transition layer region of jacket pipe 3 inner chamber, and the wire of electrolysis ring 4 stretches out jacket pipe 3 and is connected with power supply.
Jacket pipe 3 is provided with insulating plug 6, wire is connected with power supply through insulating plug 6, wire has two, cathode line and anode line, cathode line is all connected with power positive cathode with anode line, anode line is connected with electrolysis ring 4 through insulating plug 6, and cathode line stretches in jacket pipe 3 through insulating plug 6 and contacts with streaming flow.
As shown in Figure 3, jacket pipe 3 is bend pipe, and the jacket flange of this structure is applicable to pipeline corner.
When fluid flows in pipeline time, according to the size (namely apart from the size of wall distance) of viscosity length dimension, pipeline flow field is divided into viscous sublayer, transition layer and skin, research finds, when micro gas-bubble enters from transition layer, drag-reduction effect is best, therefore, by being arranged on the electrolysis ring 4 in jacket pipe 3 transition layer, the bubble that electrolysis ring 4 is produced directly produces in transition layer, in liquid flows in jacket pipe 3, the interaction in transition layer of micro gas-bubble and turbulent flow, suppress turbulence pulsation, realize turbulent flow drag reduction, reduce the surface friction drag of jacket pipe 3 course of conveying, also can reduce to enter surface friction drag suffered in subsequent pipeline simultaneously, improve drag reducing efficiency, reduce unnecessary waste, liquid speed is improved as much as possible under effect under the tolerance of same micro gas-bubble.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
