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 the water supply and sewage work technical field, specifically relate to the isometrical accurate surge shaft of a kind of aqueduct.
Background technology
Water supply and sewage work technical field saving investment, saving are taken up an area of, water supply security is the target that country and investor pursue always; Particularly to Long-distance Pipeline for Water Conveyance, because the water delivery distance has caused the water delivery resistance big, pump head is inevitable bigger; The engineering of high pressure, long distance is in termination of pumping suddenly or when closing pipeline bottom valve door suddenly; Water hammer pressure fluctuation in the pipeline is bigger, must select to satisfy the aqueduct of water hammer pressure during design, causes the water delivery engineering investment bigger.
Adopt the middle tone reservoir can solve the problem of part engineering water supply hypertonia, but there is the shortcoming that floor space is big, investment is high in the pond of regulating and storing.
Summary of the invention
The purpose of this invention is to provide a kind of isometrical accurate surge shaft of aqueduct that can reduce water hammer pressure, saving occupation of land simultaneously.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The present invention includes the accurate surge-chamber that is positioned at the Long-distance Pipeline for Water Conveyance middle part; Described accurate surge-chamber comprises isometrical straight tube, and the top of isometrical straight tube and atmosphere are provided with eccentric reducer respectively in the two bottom sides of isometrical straight tube, and the larger diameter end of eccentric reducer connects isometrical straight tube, and the smaller diameter end of eccentric reducer connects water-supply-pipe.
Said isometrical straight tube is identical with the caliber of water-supply-pipe.
The top of said isometrical straight tube connects hard hat through reinforcing bar.
Described hard hat is the umbrella shape hard hat.
Breathing area between said isometrical straight tube and the 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 manufacturing.
Adopt the present invention of technique scheme, accurate surge-chamber is arranged on length apart from somewhere, waterpipe middle part, straight-through atmosphere, thus with the Long-distance Pipeline for Water Conveyance segmentation, reduce water hammer pressure; Raise water level in the accurate surge shaft, reduce the floor space of pressure regulation facility; Finally to reach the purpose that reduces pipeline pressure, safety water supply, saving occupation of land.
This invention is used 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 purpose that saves material, practices thrift investment, the application of the isometrical accurate surge shaft of aqueduct has embodied energy-conservation themes of the times.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention;
Fig. 2 is that the A of Fig. 1 is to sketch map.
The specific embodiment
As shown in Figure 1, the present invention includes the accurate surge-chamber that is positioned at the Long-distance Pipeline for Water Conveyance middle part; Accurate surge-chamber comprises isometrical straight tube 1; The top of isometrical straight tube 1 and atmosphere are provided with eccentric reducer 2 respectively in the two bottom sides of isometrical straight tube 1, and 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 the water-supply-pipe 3 can drain into isometrical straight tube 1 smoothly, guarantees conveyance power of water.Need to prove that the whole profile of accurate surge-chamber is similar to tee piece, but be different from common tee piece be, isometrical straight tube 1 center line vertical with water-supply-pipe 3 female tube hub lines 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 confirmed according to the required pressure of back segment aqueduct.
In addition, the top of isometrical straight tube 1 connects hard hat 4 through reinforcing bar 5, and this hard hat 4 is the umbrella shape hard hat, and it is used to prevent that foreign matter from falling in the well, thereby guarantees the safety of whole accurate surge-chamber.Need to prove that the breathing area between isometrical straight tube 1 and the umbrella shape hard hat 4 is not less than isometrical straight tube 1 cross-sectional area, can guarantee that like this exhaust in the accurate surge-chamber can be discharged smoothly, do not stopped by umbrella shape hard hat 4.
And the isometrical straight tube 1 in the accurate surge-chamber is the best with eccentric reducer 2 to adopt steel work or reinforced concrete structure.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 process.
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 the isometrical accurate surge shaft of aqueduct; Two ends link to each other with aqueduct; Top utilizes isometrical straight tube 1 and atmosphere, makes Long-distance Pipeline for Water Conveyance form the mode that segmentation is supplied water, and has reduced water hammer ripple transmission length; Thereby reduce water hammer pressure effectively; Reach the purpose that reduces the aqueduct pressure rating, have non-maintaining, cost is low, save characteristics such as Long-distance Pipeline for Water Conveyance investment greatly, be particularly suitable for adopting in the Long-distance Pipeline for Water Conveyance engineering.
