Abstract
The invention relates to an equal-diameter quasi-surge shaft for a water pipe, which comprises a quasi-surge chamber located in the middle of the long-distance water pipe. The quasi-surge chamber comprises an equal-diameter straight pipe, the top of the equal-diameter straight pipe is communicated with the atmosphere, eccentric variable-diameter pipes are respectively arranged on both sides of the bottom of the equal-diameter straight pipe, the large-diameter ends of the eccentric variable-diameter pipes are connected with the equal-diameter straight pipe, and the small-diameter ends of the eccentric variable-diameter pipes are connected with the water pipe. By adopting the above technical scheme, the quasi-surge chamber is arranged somewhere in the middle of the long-distance water pipe and is directly communicated with the atmosphere, so that the long-distance water pipe is segmented and the pressure of a water hammer is reduced; the water level in the quasi-surge shaft is risen, and the floor space of the surge facility is reduced; and finally the purposes of lowering pipe pressure, safely supplying water and saving floor space are achieved.
Description
Technical field
The invention belongs to water supply and sewage work technical field, specifically relate to a kind of equal-diameter quasi-surge shaft for water pipe.
Background technology
Water supply and sewage work technical field saving investment, the target that saving is taken up an area, water supply security is country always and investor pursues, particularly for Long-distance Pipeline for Water Conveyance, because water delivery distance has caused resistance of water conveyance large, pump head is inevitable larger, the engineering of high pressure, long distance is in termination of pumping suddenly or while closing suddenly pipeline bottom valve door, water hammer pressure fluctuation in pipeline is larger, must select to meet the aqueduct of water hammer pressure during design, causes water delivery engineering investment larger.
Adopt middle tone reservoir can solve the problem of part engineering water supply hypertonia, but the pond of regulating and storing have floor space large, invest high shortcoming.
Summary of the invention
The object of this invention is to provide a kind of equal-diameter quasi-surge shaft for water pipe that can reduce water hammer pressure, saving occupation of land simultaneously.
For achieving the above object, the present invention is by the following technical solutions:
The present invention includes the accurate surge-chamber that is positioned at Long-distance Pipeline for Water Conveyance middle part; Described accurate surge-chamber comprises isometrical straight tube, and the top of isometrical straight tube communicates with atmosphere, in the two bottom sides of isometrical straight tube, eccentric reducer is set respectively, and the larger diameter end of eccentric reducer connects isometrical straight tube, and the smaller diameter end of eccentric reducer connects water-supply-pipe.
Described isometrical straight tube is identical with the caliber of water-supply-pipe.
The top of described isometrical straight tube connects hard hat by reinforcing bar.
Described hard hat is umbrella shape hard hat.
Breathing area between described isometrical straight tube and hard hat is not less than the cross-sectional area of isometrical straight tube.
Described isometrical straight tube and eccentric reducer all adopt steel or steel concrete manufacture.
Adopt the present invention of technique scheme, accurate Set surge tank is being grown apart from somewhere, waterpipe middle part, straight-through atmosphere, thus by Long-distance Pipeline for Water Conveyance segmentation, reduce water hammer pressure; Raise water level in accurate surge shaft, reduce the floor space of pressure regulation facility; Finally to reach the object that reduces pipeline pressure, safety water supply, saving occupation of land.
This invention is for the Long-distance Pipeline for Water Conveyance engineering of hydraulic engineering, power engineering, chemical engineering, urban water supply engineering etc., the use of this equipment can reduce the pressure rating of aqueduct effectively, thereby play the object that saves material, saves investment, the application of equal-diameter quasi-surge shaft for water pipe has embodied energy-conservation themes of the times.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
The specific embodiment
As shown in Figure 1, the present invention includes the accurate surge-chamber that is positioned at Long-distance Pipeline for Water Conveyance middle part; Accurate surge-chamber comprises isometrical straight tube 1, the top of isometrical straight tube 1 communicates with atmosphere, two bottom sides at isometrical straight tube 1 arranges respectively eccentric reducer 2, the larger diameter end of eccentric reducer 2 connects isometrical straight tube 1, the smaller diameter end of eccentric reducer 2 connects water-supply-pipe 3, wherein, the design of eccentric reducer 2 makes the gas collection in water-supply-pipe 3 can drain into smoothly isometrical straight tube 1, guarantees conveyance power of water.It should be noted that, the profile of accurate surge-chamber integral body is similar to tee piece, but is different from common tee piece, isometrical straight tube 1 center line vertical with the female tube hub line of water-supply-pipe 3 and with eccentric reducer 2 upper tube wall out of plumb.
In use, the smaller diameter end of eccentric reducer 2 communicates with water-supply-pipe 3, and the caliber of isometrical straight tube 1 is identical with water-supply-pipe 3 calibers.And the length of isometrical straight tube 1 can be determined according to the required pressure of back segment aqueduct.
In addition, the top of isometrical straight tube 1 connects hard hat 4 by reinforcing bar 5, and this hard hat 4 is umbrella shape hard hat, and it falls in well for preventing foreign matter, thereby guarantees the safety of whole accurate surge-chamber.It should be noted that, the breathing area between isometrical straight tube 1 and umbrella shape hard hat 4 is not less than isometrical straight tube 1 cross-sectional area, can guarantee that like this exhaust in accurate surge-chamber can be discharged smoothly, by umbrella shape hard hat 4, is not stopped.
And the isometrical straight tube 1 in accurate surge-chamber and eccentric reducer 2 take that to adopt steel work or reinforced concrete structure be best.When water-supply-pipe 3 is steel pipe, should select the accurate surge-chamber of steel; When water-supply-pipe 3 is nonmetals, the accurate surge-chamber that should select steel concrete to make.
Operating principle of the present invention is:
Because the present invention is arranged at somewhere, Long-distance Pipeline for Water Conveyance middle part.Simultaneously, water-supply-pipe 3, eccentric reducer 2 and isometrical straight tube 1 are combined, form equal-diameter quasi-surge shaft for water pipe, two ends are connected with aqueduct, top utilizes isometrical straight tube 1 to be communicated with atmosphere, make Long-distance Pipeline for Water Conveyance form the mode that segmentation is supplied water, reduced water hammer ripple transmission length, thereby effectively reduce water hammer pressure, reach the object that reduces aqueduct pressure rating, have non-maintaining, cost is low, greatly save the features such as Long-distance Pipeline for Water Conveyance investment, be particularly suitable for adopting in Long-distance Pipeline for Water Conveyance engineering.
