Abstract
The present invention relates to a valve with low energy consumption and a high flow rate, which is a valve utilizing the energy of fluid at a valve port to open and close the valve during the delivery of water bodies; thus, power needed for operating the valve is small. The valve can be controlled by hand as well as by an electromagnet. When the valve is controlled by electric power, one kilowatt-hour of electricity can open and close the valve for thousands of times. Accordingly, the present invention is particularly suitable for valves or pipeline gates with low pressure and a high flow rate and is also is suitable for valves which is directly operated or remotely controlled by people. The valve with low energy consumption and a high flow rate is especially suitable for irrigation in agriculture, water delivery of irrigation ditches in water conservancy, and tap water supply engineering.
Description
Technical field:
On the water conservancy, in the field irrigation, on domestic water, all exist the work that water body is carried in large quantities, in order to control and manage the conveying of water body, in water system, used valve and gate in a large number." low energy consumption and large flow valve " a kind of valve that comes to this is carried because it is specially adapted to the water body of big flow, and therefore aspect the sluice of using in water conservancy gate and field irrigation or small-sized dam, " low energy consumption and large flow valve " also can be applied.
Background technique:
Traditional valve all is to open and close under strength that adds and energy, and most typical has been water tap that we will use every day, because the water pipe diameter at family expenses water source is very little, water is very little to the active force of the critical component of valve.Therefore it is to utilize us to mention valve gap or the ball valve of cutting off the water supply in the pass in the turn of hand, and water is flowed, and same reverse operation can be cut off the water supply.When the diameter of water pipe has tens of centimetres even hundreds of centimetres, only use a people's strength, in fact can't the opening and closing valve, this is because the closed condition lower valve has born huge static pressure, and static pressure justice has caused huge frictional resistance; In the time the valve that mobile water is arranged will being turn-offed, because a people's strength is depended merely in hydrodynamic effect and by the frictional resistance that it causes, overcome so huge static pressure and huge frictional resistance again, be actually suitable difficulty.Therefore, actually, people usually are with a motor, drive a worm gear speed changer, just can open or throttle down by one pair of nut-screw again.And when current by area greater than after one square metre, the mode of people's gate commonly used has been treated the management at water source.
Summary of the invention:
The above fact is, no matter valve is in closing state or is in the state of unlatching, and near the of valve all is to have huge strength, but before the present invention proposes, and this strength is people's object of trying hard to overcome just usually." low energy consumption and large flow valve " then is that a kind of utilize this " huge strength " is opened or a kind of valve of throttle down.
A kind of low energy consumption and large flow valve, be to utilize valve port place fluid energy to carry out the valve of valve opening and closing, it is characterized in that: in the assembly that constitutes low energy consumption and large flow valve, two tubaeform head pieces of getting are arranged, the change-over valve (hereinafter referred to as " control valve ") of the pressure flow body whereabouts that management obtains, and the pressure flow body obtained of utilization main body valve of opening or closing, the keying of main body valve is born by the resilient bladder body of energy topping up dilatancy, or with one or more can topping up the resilient bladder body driving device member of dilatancies bear, described main body valve is moving or come the switching control valve operating mode to implement keying with the action of electromagnet with the have gentle hands flicking, this low energy consumption and large flow valve can be used as the angle valve of using on the pipeline in the conventional conception, butterfly valve, stop valves etc. also can be used as in the water conservancy feed ditch gate that is produced in the water-filling dam that constitutes with capsule or the water conservancy projects in the waterwork.
This valve is applicable to the aqueduct that the clean full packages of all water-quality ratios is carried, as tap water supply system, and the water-carriage system on the water conservancy, the water-carriage system in the field irrigation etc.Because its big Flow characteristics therefore also can be with being alternate device aspect the gate of water conservancy.
Before the present invention proposed, I never saw same working principle and am used for same design of plant, no matter am valve or gate.
Significantly the fact is that this object that people are tried hard to overcome is transformed into the energy that people achieve the goal, thereby has saved the energy that opening/shutting valve adds widely, and energy-conservation meaning is only just arranged in view of this point.With a real example this point is described, one 4 kilograms the specified maximum operating currenbt of electromagnet is 2.3 amperes, the startup time once calculates it and wants 2 seconds, operating voltage is by 220 volts of calculating, kilowatt-hour can move about 3500 times, and " low energy consumption and large flow valve " also do not want 4 kilograms power, more do not want the operating time in 2 seconds.And, the wired remote control that " low energy consumption and large flow valve " also very helps directly not contacting, this to on-farm water management, all has bigger help to large-scale water resources allotment to the management of water resources.
The meaning of " low energy consumption and large flow valve " is comparatively apparent, is but near the fluid energy this valve enough to opening/shutting valve? we know that the Bernoulli's equation in the fluid mechanics shows, ubiquitous main form of energy has three kinds in the fluid: heat energy, pressure energy, kinetic energy, transforming mutually between them is constantly to change along with the variation of fluid environment.For example when valve is in closing state, be equipped with in the pipe-line system of valve, near valve,, have potential energy, pressure energy by in the water body of water source one side; And when valve is in the state of opening, near valve, have potential energy, pressure energy and kinetic energy.The existence of this potential energy, pressure energy also can be utilized also relatively more intuitively, but that whether it is enough to overcome the impulse force of current is quite doubtful, and as for the utilization of kinetic energy, has then more suspected.Here, we illustrate the working principle of " low energy consumption and large flow valve " by the analysis to a butterfly valve.
Fig. 1 is the schematic representation that obtains pressure water source that can opening/shutting valve in order to explanation " low energy consumption and large flow valve ", shown among the figure is the valve that internal structure is temporarily removed entirely, and the valve of this moment only has been left the segment pipe that two ends also have flange.All there is the limit of digging the below of the two ends mouth of pipe among the figure, and they are exactly the tubaeform section of getting head piece, is all connecting pipe in tubaeform back of getting head piece.Among the figure shown in the arrow is water (flow) direction by valve, and therefore, the tubaeform head piece of getting on the left side is to settle against the direction of current, and the tubaeform head piece of getting on the right then is to settle along the direction of current.No matter be that tubaeform head piece of getting, the captured area of its oral area is more than 5 times of captured area of its rear portion mouth of pipe.For the tubaeform head piece of getting on the left side, water enters tubaeform getting after the head piece, because basal area reduces gradually, so flow velocity begins to increase, and the pressure energy of the water that accompanies therewith also has raising slightly.If this strand current in a single day blocked (back pressure), because the kinetic energy of fluid has become zero, thereby pressure energy will raise rapidly.This is the reason that Bernoulli's equation shows.How high this final pressure can be raised to, relevant with the ratio of the mouth of pipe with the tubaeform head piece of getting, and ratio is big more, and this pressure is just high more.In addition, this pressure also with tubaeform whole pipelines of getting behind the head piece on local pressure loss relevant with linear loss, lose big more, this final pressure is just low more, local losses is the function of flow velocity in addition, this loss also decreases when velocity in pipes is very little, in addition also can also reduce loss by improving the interior circulation condition of pipe.For " low energy consumption and large flow valve ", as long as this pressure can be enough to opening/shutting valve, because the tubaeform too big local losses that the water body of whole conveying is caused of head piece of getting also is unfavorable for the water body conveying.The tubaeform head piece of getting as for right-hand member, because tubaeform flow area minimum of getting the residing section water body of head piece (not being meant the tubaeform water body of getting in the head piece), thereby the flow velocity of water body has raising slightly, therefore the static pressure (pressure energy) of the water in the water body will be lower than the static pressure (pressure energy) of the water in the tubaeform water body of getting in the head piece here, according to fluid mechanics principle, the tubaeform water of getting in the head piece has a kind of by the tubaeform outer water trend of aspirating away of head piece of getting.Therefore these two the tubaeform interior pressure of rear tube of getting head piece are visibly different: the left side is more much higher from the pressure that the F mouth flows out than the right from the pressure of E mouth output.
Fig. 2 is the organigram of butterfly valve in " low energy consumption and large flow valve ".Among Fig. 2, the left side is the sectional drawing that valve body 1 and driver 2 are cut open along butterfly valve 8 planes, the lid 5 of driver and be installed in the control valve 6 that covers, the control button 7 on the control valve all is not broken away, we can also see driver and its lid flange connecting 4, butterfly valve 8, driver blade 9 among this figure.Right figure reveals the internal drive structure that shows after left view is removed drive covers.Demonstrate the flange 3 at valve body 1 and its two ends among the figure, " the resilient bladder body of energy topping up dilatancy " (being designated hereinafter simply as capsule) 11,12 in the driver, do not have on the demarcation strip 10 that is fixed on the drive enclosure 2, butterfly valve links to each other with driver blade 9 by axle with leaking.What right figure was now shown is to obtain next pressure water stream through behind the control valve from two tubaeform head pieces of getting, high pressure water has entered into the inside of capsule 11 by hole A, B on the capsule 11, and low-pressure water (more accurate saying should be negative pressure water) then goes by tubaeform getting in the pipe that head piece flows to downstream behind the valve forward from capsule 12 by hole C, B on the capsule 12 simultaneously.Because the pressure in the capsule 11 will be higher than the pressure in the capsule 12, and be fixed on the driver during work of the lid 5 of driver, so the work that blade 9 is under pressure is as rotating counterclockwise, until " low energy consumption and large flow valve " water source is turn-offed, till blade 9 is blocked by the block in the valve body (not showing among the figure).Double-action swing cylinder in this driver and the hydropneumatic is quite similar, different is that the working area is not to come the compartmentation zone by accurate sealing technique, but used the capsule of the resilient bladder body of topping up dilatancy " can ", this mainly is for the facility on making.If can adopt new material new process, can guarantee sealing, can separate the working zone reliably again, this capsule can save fully.For example in the gate of water conservancy, use the design, just can consider to do like this.
When having water to flow in valve body, the process of above-mentioned blade Shuttoff Valve carries out, only depend on the press water in the capsule 11 can be enough to turn-off so? we can see from the left figure of Fig. 2, there is a rotating shaft at the symmetry center axle place of blade, rotating shaft is fixed on the valve body, so blade can only sway and can not do other any motion.When the pipe stream that full packages is arranged in " low energy consumption and large flow valve " when mobile, current are to being that the torque for rotating shaft of upper and lower both sides butterfly valve 8 generations of boundary is just in time opposite with the axle, following half side effect has caused closing of butterfly valve; Upward half side effect has caused the unlatching of butterfly valve, and these two power are slightly different because of the gravity of water, but basically near balance, therefore under the help of the auxiliary external force that causes because of capsule, closing fully of valve can realize.For reliable, we allow total lifting surface area of blade be not less than the area of half butterfly valve, because the resistance that we also must cause mechanical efficiency is also taken into account.
For " low energy consumption and large flow valve " that be in closed condition, we want to open it, need only press the button 7 on the control valve 6, and the pressure water source interface of connecting in the capsule 11,12 just switches, and the capsule 12 that at this moment originally was in atrophing state begins to expand; Capsule 11 then begins atrophy, butterfly valve begins to clockwise rotate unlatching, current begin to pass through in " low energy consumption and large flow valve ", and this makes the tubaeform head piece of getting of reverse installation further obtain to change the pressure energy of coming from kinetic energy, thereby butterfly valve rotates sooner.When the plane of butterfly valve is parallel with water (flow) direction, because stopping of driver internal baffle block makes valve to rotate, so " low energy consumption and large flow valve " has been in the situation of full open again.
Which type of is the structure of control valve inside? this is different to different " low energy consumption and large flow valves ".Even with a kind of " low energy consumption and large flow valve ", design also can have nothing in common with each other, as long as can reach the direction of switching current.The internal structure of the control valve in this example as shown in Figure 3.Fig. 3 is the schematic representation of the button lateral dissection control valve in Fig. 2, show among the figure control valve about two holes be to be communicated with and to take over F and communicate with the tubaeform head piece of getting of following current among Fig. 1 by an assembly; And at vertical right-hand member of control valve a hole is arranged, only be shown as a circle among Fig. 3, be with Fig. 1 in the tubaeform head piece of getting of adverse current take over E and communicate.Also show among Fig. 3, control valve is become three chambeies by longitudinal subdivision, at lumen a bistable leverage is arranged, its effect is after pressing button, can make lumen communicate with left chamber among Fig. 3, closed the passage in lumen and right chamber and the passage of left chamber and F mouth simultaneously, also opened the passage that right chamber is connected with F interface, just as shown in Fig. 3 is present.If we press another button after this, then above-mentioned situation all switches: lumen communicates with right chamber among Fig. 3, has closed the passage that reaches right chamber and F mouth that leads in lumen and left chamber simultaneously, has also opened the passage that left chamber is connected with F interface.We know, the result of such switching is to cause capsule 11,12 among Fig. 2 and the E among Fig. 1, among the F that to join, and just valve becomes state for opening from closed condition.
" low energy consumption and large flow valve " also can be used for angle valve, a kind of structure that comes to this shown in Figure 4.Obviously visible is that such structural volume is very big, therefore whether suitably needs further discussion economically.Among Fig. 4,1 on the valve body, the 2nd obtained the position of pressure water source, and they communicate with the interface 1,2 of hand-operated direction valve.
Below all be with one or more can topping up the valve that drives of the resilient bladder body driving device member of dilatancies bear the example that " low energy consumption and large flow valve " opens and closes, another " low energy consumption and large flow valve " is self to block or open the structure that head piece opens and closes " low energy consumption and large flow valve " by resilient bladder body that can the topping up dilatancy.Come to this a kind of " low energy consumption and large flow valve " shown in Figure 5, it is suitable for small-bore " low energy consumption and large flow valve ".
The structure and the working principle of " low energy consumption and large flow valve " shown in Figure 5 are such.Two capsules are arranged in the inside of valve body, one is the barrel-shaped ring-type capsule of interlayer, be peripheral capsule, another is the column capsule of a circle of a point, be middle heart-soothing capsule, it is supported on the support width of cloth bar that radially is provided with at two ends, and the water in the middle heart-soothing capsule is also supported the input of width of cloth bar or discharged capsule by this.This " low energy consumption and large flow valve " tubaeform got the top inner surface that head piece should be located at peripheral capsule.Situation when the right figure among Fig. 5 is through-flow, the water in the capsule all drains at this moment.Behind our button (all not drawing among the figure) by brake control valve, tubaeformly to get the water that head piece obtains and begin to flow into capsule from reverse, water flow to the Lower Half of peripheral capsule before this.Flood gradually to the first half of middle heart-soothing capsule and peripheral capsule, it is very thin that runner has at this moment become, and the flow velocity of current is also become heavy, so to get the hydraulic pressure that head piece obtains also higher from tubaeform, till the capsule that current are inflated fully stops up.Left figure among Fig. 5 is exactly the section situation of this obstruction.Because in the capsule in this " low energy consumption and large flow valve " is not that into water is exactly draining, therefore the structure of the position control valve of this " low energy consumption and large flow valve " is also just fairly simple comparatively speaking.In order to prevent that capsule under the effect in water pressure excessive distortion taking place when the stifled stream and damage because of unbalance stress causes capsule material, therefore some tractive muscle can be set in the inside of capsule to be used for the unbalance stress of balance capsule material.
The press water that utilizes the said water fetching device of this patent to obtain is filled the water-filling dam of making of capsule, can intercept canal stream or make the former water channel of being intercepted open-minded.The situation that shown in Figure 6 is exactly when the water-filling dam blocks and open canal stream.Situation when wherein left figure is the water conservancy feed ditch by the stifled stream of water-filling dam; Top right plot is that the water-filling dam blocks up dam section drawing in side sectional elevation when flowing; Bottom-right graph then is the dam section sectional drawing when being drained of the press water in the water-filling dam, shows among this figure that the water in feed ditch this moment can be unimpeded.In order to make the water pressure that can be higher than the dam upstream side from tubaeform water pressure of getting the water that head piece obtains, and also to be subjected to the pressure loss inevitably from tubaeform water pressure of getting the water that head piece obtains, therefore the intake for the water-filling dam preferably is arranged on the position of capsules body near dam crest, this can make as long as current are not also blocked on the dam, intake will also continue water intaking, till blocking fully.
Can topping up the resilient bladder body of dilatancy self block or open in the control valve that head piece opens and closes " low energy consumption and large flow valve ", in order to prevent that water in the capsule is to exteenal reflux, can add the one-way valve of non-return in case of necessity, the through-flow local pressure loss of the one-way valve here must be enough little.
Fig. 7 is another kind of " low energy consumption and large flow valve ", or is called especially big angle valve, because it is more suitable for being designed to change the angle valve of the flow direction, for general consideration, Fig. 7 has been designed to not change the form of the structure of the flow direction.This also be a kind of can topping up the resilient bladder body of dilatancy self block or open head piece and open and close " low energy consumption and large flow valve ".In Fig. 7, valve body 1 middle part crossfades into rectangular cross section, and inside is provided with tilting through-flow fence 6 (shown in the A-A of Fig. 7 right side), and fence below is provided with malleation and dams mouthfuls 2 and its drainage tube 3; Negative pressure dams mouthfuls 5 and its drainage tube 4, article two, pipeline 7 is sent to bistable two position three-way valve 8 along the fence bottom, the capsule 9 of this valve has only one, it because of its internal fixation has curling steel wire to be crimped onto side suspension when valve opening, when needs opened and closed valve, the malleation mouthful beginning drainage of damming made capsule 9 water-filling gradually, the weight of water is launched capsule gradually, and last whole pressure reduction because of both sides about the through-flow fence turn-offs current (shown in Fig. 7 left bottom).In order to reduce the local losses of valve, therefore the flow area of fence should be greater than the nominal flow area of valve correspondence, in the A-A view, the garden 10 included areas that with dashed lines is drawn are to equate with the circulation area of fence, and the flow area of valve inside nominal diameter then equates with the garden 11 of drawing with double dot dash line.
In sum as can be known, " low energy consumption and large flow valve " is the valve that the fluid energy of a kind of Guan Liuzhong of utilization is closed or opened, and the switch of operating this valve only needs few strength, thereby it is very suitable for carrying out remote control." low energy consumption and large flow valve " is applicable to agricultural irrigation and water conservancy and the application of public waterworks aspect very much.
