The specific embodiment
See Fig. 1, a kind of bypass type pumping device that draws water comprises water inlet pipe 1, gutter 2, and characteristic of the present invention is, water inlet pipe 1 and gutter 2 adopt one section curved pipe 3 to be connected, and wherein gutter is longer than water inlet pipe; Be communicated with air inlet pipe 4 on the top of arc pipe 3, and air inlet pipe is provided with admission valve 5; On gutter 2, be positioned at the water inlet pipe mouth of pipe to be arranged with admission pipe 6, admission pipe is provided with inlet valve 7, and is provided with flap valve 8 after on admission pipe, being positioned at inlet valve 7; , gutter 2 bottoms are provided with draining valve 9 below being positioned at admission pipe.
A is a waterline, and C is a water (flow) direction.
Present embodiment is that pumping device is placed the sketch map that draws water in the pond 10, and wherein the dotted line in the pond 10 is a horizontal plane.
Pumping device of the present invention be applicable to the high water level pool to the field of low water stage, irrigate or irrigation canals and ditches, river course pump drainage water conservancy project are done, and can apply to initiatively flood discharge place such as get rid of the danger of river course in flood season, reservoir.Draw water height (being the pond degree of depth) according to the local height above sea level decision of the former reason of atmospheric pressure, and theory is drawn water highly the highest 10.33 meters.Draw water in about 2000 meters areas of height above sea level and highly approximately can reach 8.5 meters.
Operating principle of the present invention:
The bypass type pumping device is by external force (various evacuators or direct with the artificial air-breathing mode) air in the pipeline between valve to the horizontal plane of finding time; Close inlet valve → open draining valve then; Utilize the atmospheric pressure principle to carry out the pump drainage water conservancy project automatically and do, do not need power input constantly.End-of-job is opened the work of drawing water of top admission valve and is stopped.
Its operating principle is similar to the operating principle of circuit the inside start button open in usual, and inlet valve and suction device only play the startup effect.
Pumping device of the present invention and the difference that has facilities such as widely used various water pumps now:
1) existing water pump draws water and all must the water pump continuous operation continue consumes energy, and flow is determined by pump power.Present vast rural area every rainy season will be extracted out from the field with pump handle water and will be discharged in the ditch, and little pump efficiency is low, and big water pump not only costliness but also heaviness also will consume a large amount of energy.The bypass type pumping device no longer needs the power input after starting device starts.Flow is by the decision of the water-head between main drainpipe caliber and water inlet plane and the delivery port, and is irrelevant with starting device.
2) a small-sized starting device can successively start many big caliber pumping devices, and the superiority of this function is particularly outstanding in work is got rid of the danger in flood season river course, the flood discharge of the pool, dam.If when the active flood discharge, take the mode draining of dykes and dams opening, the uncontrollable and water that flow out of displacement and water discharge time causes more easily bank erosion and breaches a dyke.If use the water pump draining, the displacement of several small-power water pumps is very limited.If use many high powered water pump drainings, at first hard transportation.Moreover the injury that the resonance that is caused by many pump workings causes embankment has aggravated the danger of breaching a dyke especially.If use this pumping equipment, not only can many pumping devices be drawn water, and need not take care many water pumps and work simultaneously and cause resonance with one to two starting device.Also have several meters just drainings in good time at water level from the embankment eminence, how many platform equipment drainings displacement can determine with at any time as required or stop draining.The following water-supply-pipe of draining valve can extend arbitrarily in addition, makes delivery port away from dykes and dams.
3) this water plug can be designed to interim or permanent installation according to the frequent degree of work.Also can remove valve, pipeline refills valve as permanent facility in the time of work, convenient and swift, has solved the difficult problem that field facility is difficult in maintenance, expense is high.If a whole set of as permanent facility, through the admission valve release, all valves were in idle state at ordinary times after work was accomplished, thereby prolonged the application life of facility.Compare conventional method, basin bottom is installed delivery port, valve short, replacing inconvenience in application life, the stolen easily or malice discharging in leakage easy to crack of outlet pipe place and water source.Use middle-size and small-size water conservancy projects as individual or all irrigations of small collectives; Use this water plug; The whole pouring in the mouth of a river is not reserved in the pool, dam bottom, is installed separately starter gate valve, admission valve in the shelter, can effectively prevent to leak, water resource is stolen or the waste that causes damage such as malice discharging.Very easy to use, directly just can work with artificial air-breathing mode.
As shown in Figure 2 for the small-sized household pumping device, A is a waterline, and C is a water (flow) direction.
Like Fig. 2; Fig. 3; Shown in Figure 4, the flap valve that installs additional at the back at draining valve for the small-sized household pumping device is the manual exhaust plant 11 of elastic rubber of a band non-return, and this device comprises elastic bag 12 and non-return structure fixing body 13; One end of rubber pneumatic bag 12 is connected with admission pipe 6, and the other end of rubber pneumatic bag 12 is connected with the non-return structure fixing body 13 of tubular; Be provided with O-ring seal 14 at non-return structure fixing body 13 near an end of elastic bag 12; Be plugged with the conical plug 17 of band stopper rod 18 in the O-ring seal 14, stopper rod 18 is inserted in the sliding eye 16 on the conical plug mount pad 15 that is positioned at non-return structure fixing body 13 ports of export; On stopper rod 18, be with tensioning spring 19.
The flap valve 8 that installs additional at the back at draining valve is the moving exhaust plant of elastic rubber player of a band non-return, does not just need to dispose special starting device again, and is very easy to use.Its course of work: water inlet pipe mouth reaches below the water surface → closes admission valve, draining valve → open inlet valve → (air-breathing) pump that draws water and starts working and evenly flow out → close inlet valve to water and open the draining valve system simultaneously and get into operate as normal → open the admission valve work of drawing water to stop.
4) because having increased flap valve after inlet valve, this water plug prevents to be interrupted the backflow of breathing process air; And the caliber of suction bypass can design very for a short time; So, even under the situation of no any starting device, also can start the water plug of big caliber remote (hundreds of rice even farther) with the most original artificial air-breathing mode.Conventional method with mouthful air-breathing everyone can use and all use, but oil or water that can only sucking-off tubule footpath short distance (maximum tens meters far away).
5) if water level is darker, then above appropriate location (water-column that can press with local atmospheric pressure is as the criterion) installed outlet pipe in the bottom, gets final product with flangeseal behind the position of reservation mounted valve.Just need change valve when the water level that single order can be taken out in pump process, having only is lower than this delivery port and connect gutter, thereby avoid the valve band to press standby time long, the time spent does not open or oneself can't close after inefficacy is opened.Thereby multistage gutter can be installed by that analogy to be realized the automatic drainage works of swimmer's pool and avoids band to press maintenance.
The present invention is applied widely, can realize with state-of-the-art far distance automaticization control technology, also can realize with the most original artificial air-breathing mode.Big draining to several thousand cubes of per seconds, little all very practical to the field agricultural water.As the pump drainage wetting system of general small hydraulic project, 8 to 9 meters oneself warp of the degree of depth that draws water is enough.
In the place that poultry pond more than the hundreds of side is arranged, it is very necessary to be equipped with this water plug of several covers especially.Because any advanced person's equipment all can break down, run into that the mountain is broken out and original drainage system of installing when breaking down, in a few minutes this equipment is devoted oneself to work, clear.
This facility is used for river course, large reservoir initiatively during flood discharge, can be away from dykes and dams, and the start-up control system is installed in the place of spacious safety, starts many gutters simultaneously and need not take care starting device and cause the injury of common shake to dykes and dams, and act freely.Thereby be implemented under the prerequisite of not breaching a dyke, come temporarily the purpose of flood discharge peak clipping at flood peak.Flood discharge under planned, the preceding topic that can control can be avoided casualties fully, also can not cause great loss to other property, therefore also there is no need when situation is critical very much, just to begin flood discharge.If this facility river course in similar this year tragedy that breaches a dyke is arranged can be avoided fully.
When being purpose with the flood discharge, should adopt the gutter of big caliber to increase flood carrying capacity as far as possible, under the prerequisite that evacuating equipment allows, suitably strengthen the suction line diameter, so that system gets into duty as early as possible:
Because the flow velocity of liquid is similar to the 4 powers relation of radius, i.e. V ≈ KPr under the uniform pressure condition
4Flow Q=SV=π r
2.KPr
4=π KPr
6(K is the constant value of a certain liquid under the certain pressure condition; P is the pressure under a certain condition) regularly π, K, P are constant to put one at the pump drainage water level; Flow becomes 6 powers relation with radius; Not that long-pending the increasing of simple pipeline section is twice flow and increases thereupon and be twice, but increase manyfold, so should adopt big caliber drainage system to increase flood carrying capacity as far as possible.Use this pumping device drainage system caliber not receive the restriction of starting device caliber, just in time can satisfy this requirement.
So: the present invention can make things convenient for numerous people to protect the masses' productive life, reduces production costs; And can be used to administer the river course and improve public water conservancy projects, effectively reduce the generation of natural calamity.If this facility can come into operation in a large number, the operation of drawing water will reduce mass energy consumption for the user with substituting traditional water pump.Energy-saving and emission-reduction overall situation in current entire society advocated is also very identical, will produce certain economic benefits and social benefit, and the protection broad masses of the people security of the lives and property when the active flood discharge is removed the flood meaning and existed simultaneously.
The course of work is: water inlet pipe mouth is reached below the water surface → close admission valve, draining valve → open inlet valve → (air-breathing) pump that draws water and start working and evenly flow out → close inlet valve to water and open the draining valve system simultaneously and get into operate as normal → open the admission valve work of drawing water to stop.
It should be noted that:
1) if aspirating air pipe is very long, as long as use transparent tube then to see in the pipe between water inlet to the draining valve not having air, can close inlet valve, open draining valve and make system get into work as early as possible, and needn't wait aspirating air pipe water to flow out.
2) aspirating air pipe can not closed, remove pumping equipment after the adjunction water-supply-pipe directly also can as the water pipeline.
3) in inlet valve back (good more closely more) flap valve is installed, is prevented that manual work is interrupted air-breathing and other pumping equipment breathing process air refluxes, with smooth evacuate air apart from inlet valve.
4) if just short time work is interrupted, then do not open admission valve, and select to close draining valve, just as using tap water to get final product with hand switch.
Installation specification of the present invention:
1) all pipelines, valve must can not have leakage phenomenon by good seal.
2) position of admission valve and water pipe connector must be higher than the water inlet water level, is preferably in the dykes and dams highest point.
3) position of draining valve and inlet valve must be lower than the water inlet water level, thereby low more easier emptying inner air tube smoothly gets into duty fast.
4) every grade of degree of depth of drawing water of design and installation is slightly less than the water-column (static relatively pond) that local atmospheric pressure can have been pressed.For the river course that the flows height that draws water: water inlet is installed over against water (flow) direction: drawing water highly equals the water-column that atmospheric pressure can press and adds the height that dynamic energy of water flow changes into potential energy.That is: H=H1+H2
H1=10.33 rice H2=V
2(g is acceleration of gravity 9.8/ second to/2g
2V is the speed of water flows)
With the coastal area is that example is calculated, and supposes that river speed is 5 meter per seconds, then:
H2=1.28 rice
H=10.33+1.28=11.61 rice
That is to say, not be used in the riverbed opening and just can the water at 11.61 meters below the embankment directly be drawn flood discharge or in order to irrigate.
5) be calculated as the calculated value under the perfect condition more than, altitude consideration variation and kinetic energy are converted into the energy loss in the potential energy process in the practical application.
6) drawing water under the inactive state highly satisfied the reckoning value through experiment, and because of no experiment condition, only just prediction equation does not pass through experiment as yet under the flow regime.
The production design of related components of the present invention:
1) valve directly buying as required for reducing the part kind, increases interchangeability, and admission valve and inlet valve and connecting tube are selected for use with a kind of specification as far as possible.Flap valve can be made as various forms according to the purposes difference, also need purchase special flap valve if be installed in permanent facility and high-power, the big caliber drainage system for the stability of assurance work.
2) anterior gutter is because need to install the method that flap valve, admission valve, water inlet pipe and inlet valve should adopt order; Producer by the professional production pipe fitting directly processes the required parts of mounted valve for producing; Adopt production to reduce link as far as possible, thereby effectively reduce the job stability that the probability of leaking improves system.
3) pipeline below the draining valve need not considered leakage, stress problems, can adopt various water-supply-pipes, arbitrarily lengthening.
4) the water inlet pipe mouth of pipe partly will be designed to adjustable telescoping tube, regulates at any time according to the water level height.If as the river course pump drainage wetting system that flows, water inlet partly will be done quite firmly, otherwise can not normally use because of the water impact distortion.
