Description
A kind of quantitative water control valve pipe, Qi fill device and its quantitative water method and technology field
The present invention relates to the device and method that a kind of characteristic using water in capillary carries out infiltrating irrigation, specifically a kind of quantitative water control valve pipe, irrigation device and its quantitative water control method.Background technology
In irrigation technique, the big more options of method of more water-saving efficient are directly supplied water with a small amount of water to the root of plant, can so be reduced the evaporation of irrigation water and be permeated the ground, and improve the utilization rate of water, also referred to as localized irrigation's method, such as drip irrigation.This method is that pipeline water is directed directly towards near the root system of plant, and the device for carrying scattered hole using water dropper etc. provides a small amount of and lasting water supply to plant root.To ensure a range of balanced water supply, it is necessary to think the pressure for keeping pipeline certain, unit interval water yield depends on the aperture size and pipeline hydraulic pressure power of micropore.This kind of system all needs to lay water supply line, to also having many requirements in terms of landform, hydraulic pressure, 7j matter and power.This is not suitable for for supplying water compared with scattered Planting Patterns and the larger planting environment of topography variation, such as field afforestation, the greening of road and rail both sides, economic forest plantation etc..
In order to solve the above problems, it is thus proposed that without laying the small water source irrigation technique of feed pipe, as disclosed in Publication No. CN2492060Y Chinese utility model institute patent water-saving drip irrigation water bag.It is that, using water bag as Water-storage bag, outlet pipe is connected with speed regulator, and water yield is controlled with speed regulator.But this drip irrigation bag needs labor management collecting using process, be not suitable for the forest culture and management engineering of large area.
Publication No. CN2364678Y Chinese utility model patent discloses a kind of Drip irrigation bag.It is, by a section forward end seal, and the delivery hose of several capilar bores to be opened up the water in Water-storage bag at sealing or on tube wall, direct water towards the device of plant root.Although it realizes simple, portable purpose, only lean against at sealing or several tubule holes that tube wall is opened are can not to realize that accurate towns controls the purpose supplied water surely, and can not extensive use due to lacking simple and effective control sailor section.The defect is mainly manifested in：(1) under prior art conditions, the aperture of size is extremely difficult required for can accurately being outputed on general water transferring line, and smaller to be more difficult to accurately, the minor variations of orifice size are to so the water yield of the container of all continuous water outlet will have a huge impact all the time.Therefore water yield is controlled by perforate size, can only be in one very general water supply category, it is difficult to accurate.（2) because Water-storage bag reclaimed water is constantly lost in, pressure also just constantly decline can so directly influence the flow velocity of water, when afforesting in the wild in addition,
In Water-storage bag water temperature over-high in bag can be caused to injure plant just blunt system by mouth solarization overlong time, this is accomplished by capping cover from sun or is embedded to underground, can so increase the amplitude of pressure change, so that the changes in flow rate of water is bigger.
Plant capillary irrigation method, such as Publication No. are proposed in nineteen nineties somebody
CN1064987A, CN1329819A, CN1347638A Chinese invention patent.But these are used capillary as suction hose and water-supply-pipe in the prior art, only recognize curbing function of the water surface tension in capillary, influence without recognizing other correlative factors of the water in capillary suffered by motion and standstill, such as：Influence of the change of the special role of capillary exit surface tension, influence of the variation in water pressure to the water-carrying capacity in capillary, and capillary pipe length to water-carrying capacity.Thus lack comprehensive understanding to capillarity principle.Therefore, the irrigation method and device mentioned in those inventions all can not carry out the automatic control water of prosthetic management by pressure variations influence control within the acceptable range, and can not be according to surrounding enviroment condition（Soil, pressure）It is accurate to determine to release water speed.The content of the invention

As shown in Fig. 1-4, the invention provides a kind of quantitative water control valve pipe 1, it includes surrounding layer 11 and the inner core 12 being arranged in surrounding layer 11, described inner core 12 is made up of the porous media 121 or bundle of capillary tubes 122 for playing capillarity, the scope of the maximum diameter of hole of the porous media 121 or bundle of capillary tubes is 0. 1-200 microns, and the length of water control valve pipe 1 is at least 100 times of the maximum diameter of hole of porous media 121 or bundle of capillary tubes 122.（The assay method of maximum diameter of hole can refer to chinese national standard GB/T 1967- 1996).
General a diameter of 0. 5-1. 2 millimeters of drip irrigation emitter pore, dripping end flow 1. 5-I per hour2Rise, pressure of supply water is more than 0. 3 MPas.And the present invention continually and steadily releases water for a long time from realization, to select the length of suitable capillary inner diameter and water control valve pipe 1 to do many experiments, therefrom selecting can make it play capillary diversion in root system of plant absorption region, can play again at least in normal pressures（Water-storage bag pressure can be within the third constellations to 1000 handkerchiefs under general nature state）The lower capillary inner diameter scope for preventing water from arbitrarily flowing out is 0. 1 microns -200 microns.It can make the pressure change of the pipe water inlet of water control valve 1 be in the scope that plant micro-irrigation technology allows to the influence degree of seepage velocity.
The larger control water Gang pipes 1 in selection maximum diameter of hole are conducive to absorption of the root system of plant to water, but influence of the pressure change to water-carrying capacity is also increased；Although maximum diameter of hole is too small to be greatly improved the anti-pressure ability of water control valve pipe 1, water uptake by plant roots will also result in difficult.Therefore the maximum diameter of hole of the porous media 121 or bundle of capillary tubes 122 ranges preferably from 0. 1-50 microns.The scope of the maximum diameter of hole of the porous media 121 or bundle of capillary tubes 122 can be more preferably 0. 1-20 microns.The scope of the maximum diameter of hole of the porous media 121 or bundle of capillary tubes 122 can still more preferably be 0,1-5 microns.Through experimental results demonstrate most preferably 1-5 microns of the scope of the maximum diameter of hole of the porous media 121 or bundle of capillary tubes 122.Within this range without artificially regulation water supply flow or maintain pressure of supply water, flow can control it is fairly small, and ensure water source in the case of, can constantly supply water.
Because the water control valve pipe 1 in the present invention is that water is guided into delivery port from water inlet by the capillarity of its inner core 12, the passage of water is more small, as capillarity in soil, is not easy to block on the contrary.Experiment is proved, even if will can not also be controlled using muddy muddy water using the water control valve pipe 1 of the present invention
Water valve pipe 1 is blocked.
In the present invention, it is preferred that, the length of the water control valve pipe 1 can be 400 times or more than 400 times of the maximum diameter of hole of porous media 121 or bundle of capillary tubes 122, further to reduce influence of the pressure change of the water inlet end 14 of water control valve pipe 1 to seepage velocity, improve quantitative crystal's degree.
The definition of maximum diameter of hole in the present invention is：The capillary aperture suitable with the restrained force to water produced by porous media 121 or bundle of capillary tubes 122, its restrained force to water is embodied in the maximum pressure that water control valve pipe inner core can bear water outflow.Just there is water to be forced out from the other end when such as 12-the end of inner core of water control valve pipe 1 being applied and exceeded equivalent to 3000Pa pressure（Or suction out）And the water in capillary can bear the numerical value pressure and also not make the maximum diameter of hole of water outflow be that 100 microns, the then porous media 121 of the inner core or the maximum diameter of hole of bundle of capillary tubes 122 are 100 microns.Need exist for explanation is that bundle of capillary tubes is influenceed to the restrained force of water by wherein maximum diameter of hole capillary, therefore the maximum diameter of hole of the water control valve pipe 1 by inner core of bundle of capillary tubes is equal to capillary aperture maximum in the bundle of capillary tubes；And the water control valve pipe 1, when releasing water in soil, other smaller aperture due capillaries also play certain effect.Therefore, for the ease of grasping water control valve management and control water and releasing the rule of water, such as from the inner core 12 that bundle of capillary tubes is water control valve pipe 1 of the present invention, then it is preferably selected the bundle of capillary tubes 122 of same apertures capillary composition, such water control valve pipe 1 is completely the same due to capillary inner diameter therein, length, then the control water that its each capillary serves is also just the same.The maximum diameter of hole of water control valve pipe 1 is equal to the capillary aperture in the water control valve pipe 1 in this case.What the present invention was selected in 200 micro- jujube maximum diameter of hole experiments is exactly the water control valve pipe of the capillary composition of 1.0 200 micron pore sizes, and its maximum diameter of hole is identical with capillary aperture.
Further, the big I of the maximum diameter of hole of porous media 121 described in the present invention or bundle of capillary tubes 122 is met：Water control valve pipe 1 is under non-infiltrating irrigation state, and component of the maximum surface tension that the water of its water side 13 can be formed along tube wall direction is more than or equal to pressure of the water along tube wall direction.
The surrounding layer 11 of water control valve pipe 1 can be the tubing taken blocking effect in the present invention; can also the outer layer of inner core 12 of capillarity is blocked, so as to obstruct tubular protective layer formed by the extravasation of the moisture content of inner core 12 after treatment; it is to ensure that water reaches the port of export from its arrival end by inner core 12 that it, which is acted on, so as to play the porous media 121 of capillarity in inner core 12 or bundle of capillary tubes 122 plays control action to water.
So, above-mentioned inner core 12 is used to possess the porous media 121 of numerous capillaries or the water control valve tubular construction of bundle of capillary tubes 122, and water is on the one hand guided into delivery port from water inlet using surface tension larger in capillary；On the other hand the power for acting on liquid and liquid surface by capillary wall controls it to flow.Such as
Show, when liquid is flowing out the exit of capillary duct, the pressure P of the water pressurized flow direction in the direction of the component Fly along tube wall direction and tubule for the surface tension F1 that head surface is formed（That is the trend direction M of water pressurized flow) on the contrary, the resistance as water outlet, can prevent water from flowing out capillary in the range of certain pressure, the capillary is carefully prevented from the water outflow of equivalent pressure to a certain extent, serves the effect of water valve pass；And it is as shown in figure 12, in the capillary contact to other porous medias（Such as soil）When, the surface tension of head at the pipe water outlet is destroyed, component F2ys of the surface tension F2 of capillary formation in porous media along tube wall direction turns into the gravitation for flowing out water, its direction is just identical with water (flow) direction N, water in capillary is continuously outflowed in the presence of component F2y, serves the effect that water valve is opened.Because the water control valve pipe 1 of the present invention is under non-infiltrating irrigation state, component Flys of the surface tension Π that the water of its water side 13 can be formed along tube wall direction is more than or equal to pressure P of the water along tube wall direction, therefore, the water side 13 of water control valve pipe 1 will not flow out water before not contacting soil, and the pressure of the increase certain value of water inlet end 14 will not also be such that the water in water control valve pipe is flowed out from water control valve pipe or seldom outflow；And after water control valve pipe water side is contacted with soil, water stably will ooze out from water control valve pipe 1 in the presence of soil capillary force F2.This not only realizes the full automatic water supply at independent small water source, realize zero energy consumption irrigated for a long time, and provide extremely easily condition for field water storage, carrying, construction and plantation, the small water source of independence is irrigated this inexpensive extensive use of new irrigation method. .
In the present invention, because water control valve pipe 1 is the path of water supply, it is obvious that the porous media 121 or bundle of capillary tubes 122 for constituting the inner core 12 of water control valve pipe 1 should be what water wetted material was made.But the reduction in surface tension to prevent the connection due to liquid level on adjacent pore from causing, as shown in Figure 2, porous hydrophobic substance 16 can also be covered in the end face of the water side 13 of water control valve pipe 1, or processing is modified to its end face, it is allowed to possess hydrophobic character, so as to the control water effect of more efficiently performance water control valve pipe, freely flowing out under non-irrigation state water is prevented.

Experiment 1:The use of the maximum diameter of hole of water control valve pipe 1 is 20 microns, the sectional area of water control valve pipe 1 be 1 square of millimeter, when intercepting 20 centimeters long, after the delivery port of water control valve pipe 1 completely attaches to soil, it is ensured that 1 kg of water Dry under placement naturally is put 80. 2 days；In the above conditions when continuing to increase l OOOPa pressure, then release time foreshorten to 75. 2 days, release the impacted amplitude of water speed within 7 %；And when being 10 centimeters by intercepted length shortening half, 1 kg of water places release time and also shortens half for 40. 9 days naturally, continuing to increase pressure l OOOPa release times also shortened half for 38. 3 days, released the impacted amplitude of water speed also within 7 %.It can be seen that, under the maximum diameter of hole, although releasing water speed has certain sensitive for 7 % to buckling, but the influence of the length of water control valve pipe 1 has more decision meaning, its length is inverse ratio linear relationship with flow velocity, as long as i.e. correlated condition is constant, it is possible to by selecting water control valve length of tube accurately to determine to release the water time.Such as under above-mentioned l OOOPa pressure conditions, if thunder will release water time lengthening by 1 Q0 days, this kind of water control valve pipe 1 of 26. 6 centimeters of length need only be intercepted.Its longer length of water control valve pipe 1 and the corresponding relation for releasing water speed are more accurate, more short then error is bigger, after measured when the length of water control valve pipe 1 is more than 100 times of its maximum diameter of hole, then its length is with releasing the error of water speed corresponding relation just in tolerance interval.Such as under the conditions of above-mentioned maximum diameter of hole, water control valve pipe can not be shorter than 0. 2 centimeters.
Influence experiment of the length to flow is seen again：One kg of water is by 20 micron pore sizes, when water control valve length of tube is 400 times of aperture, i.e. 0. 8CM, and nature # put the time for 1. 66 days;When continuing to increase l OOOPa pressure, its release time be 1. 55 days, be stressed influence degree within 7%, with above same apertures more than the length the wealthy pipe of control water suffered by it is identical pressure ' power influence degree it is suitable；A same kg of water is under the aperture, and water control valve length of tube is that 100 times of aperture, i.e. length are 0. 2CM, and nature release time is 153 minutes；When continuing to increase l OOOPa pressure, its Dry put the time for 135 minutes, the influence degree that is stressed reaches 12%, has a great difference with the influence degree of uniform pressure suffered by water control valve pipes more than lower 400 times of aperture lengths of same apertures, but its value is still in tolerance interval.
When the water control valve pipe delivery port is not in contact with soil（When hanging）, the water inlet of water control valve pipe 1 is when bearing the pressure within 15000Pa, and the water in the control wealthy pipe 1 of water will not be extruded away from delivery port, it means that be transported in this pressure, even if water control valve pipe delivery port is not closed, water also will not flow out.
The above-mentioned maximum diameter of hole of water control valve pipe 1 is constant, the sectional area of water control valve pipe 1 double for 2 square millimeters when, when intercepting 20 centimeters long, after the delivery port of water control valve pipe 1 completely attaches to soil, it can ensure that 1 kg of water discharges 41. 3 days in the case where placing naturally, it is released the water time and releases the water time equivalent to same maximum diameter of hole water control valve pipe 1 square millimeter 10 centimeters long；In the above conditions when continuing to increase l OOOPa pressure,
Then release time foreshortens to 39. 1 days；And when being 10 centimeters by intercepted length shortening half, 1 kg of water places release time and also shortens half for 20. 4 days naturally, continue to increase pressure l OO OPa release times also Shrink short half for 19. 3 days, release the impacted amplitude of water speed all within 7 %.It can be seen that, water control valve tube section product has equivalence to the influence and length of releasing water speed, only its sectional area and flow are direct ratio linear relationship, as long as that is, correlated condition is constant, by selecting water control valve pipe area accurately to determine to release the water time.Its reason is that the sectional area of water control valve pipe 1 constitutes for numerous capilar bores, and its area, which increases to be twice, means that number of capillaries contained therein is also doubled, therefore it is released water and also inevitably enlarges one times.But the selection of the sectional area of water control valve pipe 1 and length is also having not same-action using upper：The sectional area of water control valve pipe 1 production when it has been determined that afforestation when can only be chosen in general water supply coverage and adaptable sectional area water control valve pipe 1;The length of water control valve pipe 1 but can arbitrarily be intercepted as needed in afforestation, to reach the purpose for accurately releasing water on demand.
Experiment 2:It is 6 square millimeters that using water control valve pipe maximum diameter of hole, which be 5 microns, water control valve tube section is accumulated, when intercepting 10 centimeters long, after water control valve pipe delivery port completely attaches to soil, it is ensured that 1 kg of water discharges 102. 4 days in the case where placing naturally；In the above conditions when continuing to increase l O OOPa pressure, then # is put the time and only foreshortened to 101. 1 days, releases the impacted amplitude of water speed within 2 %；And by intercepted length to shorten half be 5 centimeters when, 1 kg of water places release time naturally, and also to shorten half be 51. 7 days, and continuing to increase l O OOPa release times, also to shorten half be 50. 9 days, releases the impacted amplitude of water speed also within 2 %.As can be seen that under the maximum diameter of hole, the influence of l OO OPa pressure versus flow speed oneself through very small.Its length is inverse ratio linear relationship with flow velocity.Water control valve pipe can not be shorter than 0. 05 centimeters under the conditions of the maximum diameter of hole, then its length and release the error of water speed corresponding relation just in tolerance interval.When the control wealthy pipe delivery port of water is not in contact with soil（When hanging）, water control valve pipe water inlet is when bearing the pressure within 60000Pa, and the water in water control valve pipe will not be extruded away from delivery port, it means that transported in this pressure, even if water control valve pipe delivery port is not closed, water also will not flow out.
The above-mentioned maximum diameter of hole of water control valve pipe 1 is constant, the sectional area of water control valve pipe 1 double for 12 square millimeters when, when intercepting 10 centimeters long, after water control valve pipe delivery port completely attaches to soil, it can ensure that 1 kg of water discharges 52. 1 days in the case where placing naturally, what it released equivalent to 6 squares millimeters of water time same maximum diameter of hole water control valve pipe 5 centimeters long releases the water time；In the above conditions when continuing to increase l OO OPa pressure, then release time foreshorten to 51. 3 days；And when being 5 centimeters by intercepted length shortening half, 1 kg of water places release time and also shortens half to be 26. 1 big naturally, continuing to increase pressure l OOOPa release times also shortened half for 25. 7 days, released the impacted amplitude of water speed all within 2 %.
Two groups of real long-mouth dog results more than, although influence of the pressure change to flow velocity is also larger when maximum diameter of hole is larger, but as long as the scope of pressure change can determine, water is released by selecting the water control valve pipe of appropriate sectional area and accurately determining its length just can accurately give, even in this sense larger maximum diameter of hole(Water control valve pipe 1 its control to current be also accurate.Therefore, for output is larger and the water supply situation of pressure change less, the larger water control valve pipe 1 in maximum diameter of hole may be selected;For the water supply situation that output is smaller or pressure change is larger, the less water control valve pipe 1 in maximum diameter of hole may be selected.Certainly, the quantity of capillary in water control valve pipe 1 is increased or decreased（Show as the increase and decrease of water control valve tube section product）Also the output of water control valve pipe can be directly affected.Flow is directly proportional to the sectional area of water control valve pipe 1 herein, and this has determined when making water control valve pipe 1；In use, according to plant regimen condition, estimated water supply time should be needed to intercept the corresponding length of water control valve pipe 1, the length of water control valve pipe 1 is inversely proportional with flow in the maximum water supply coverage that water control valve pipe 1 can be controlled effectively.
The light loam of the soil that uses for loess plateau is tested above；The water control valve pipe of the identical maximum diameter of hole different cross-sectional of this experiment is necessarily made of the porous media of identical material, therefore just has comparativity.
Based on above-mentioned result of the test, the invention provides the method for following quantitative water：This method includes following steps：
A, selection length are L0, and sectional area is SO, the maximum diameter of hole water control valve pipe 1 corresponding with environmental pressure of capillary therein;
B, the rate of release of the above-mentioned water control valve pipe 1 of measure in its natural state, and its most short rate of release under maximum pressure of supply water, obtain the rate of release scope V0 of water control valve pipe 1;
C, rate of release scope V as needed, the length L and sectional area S of water control valve pipe needed for being obtained according to following relations:
(1) rate of release V is inversely proportional with controlling the length L of the wealthy pipe of water；
(2) rate of release V is directly proportional to the sectional area S of water control valve pipe；
D, the water control valve pipe 1 for meeting rate of release is connected on water container 2, the soil near its water side 13 contact root system of plant carries out quantitative infiltrating irrigation.
Test as described above described in 1 and experiment 2, in actual application, suitable water control valve pipe 1 is obtained for ease of contrast, in above-mentioned step C, the sectional area S that water control valve pipe 1 can be fixed is constant, the length L of the water control valve pipe 1 needed for obtaining according to the following equation:
L= (VO x LO) /V
Then, the water control valve pipe 1 needed for then being obtained according to required length interception.
Alternatively selectable embodiment, in above-mentioned step c, can also fix water control valve pipe
1 length is constant, the sectional area S of the water control valve pipe 1 needed for obtaining according to the following equation:
S = (V x S0) /V0。
Then, the water control valve pipe 1 needed for then being obtained according to required sectional area.Such as test 1, described in experiment 2, control water speed scope needed for this kind of method is applied in general to for institute's measures control water scope integral multiple when, several water control valve pipe again is used accordingly according to the multiple.
Further, as it was previously stated, in Bu Sudden A, the selection to capillary maximum diameter of hole in water control valve pipe 1 can be determined according to the change of required output and following relations of maximum diameter of hole：
Maximum diameter of hole is bigger, output be stressed change influence amplitude it is bigger, output change is bigger, conversely, maximum diameter of hole is smaller, output be stressed change influence amplitude it is smaller, output change is smaller.
So, as long as pressure history under will appreciate that certain pore size, it is possible to accurately produce the water control valve pipe for meeting water supply time requirement.
Shown in Fig. 5-10, present invention also offers a kind of quantitative micro-irrigation device using above-mentioned water control valve pipe, it include water container 2 and be connected to the water container 2 and with the wealthy pipe 1 of above-mentioned control water of the inner chamber UNICOM of the water container 2, the water control valve pipe 1 is equally including surrounding layer 11 and the inner core 12 being arranged in surrounding layer 11, the inner core 12 of described water control valve pipe 1 is made up of the porous media 121 or bundle of capillary tubes 122 for playing capillarity, the scope of the maximum diameter of hole of the porous media 121 or bundle of capillary tubes 122 is 0. 1-200 microns, the length of water control valve pipe 1 is at least 100 times of the maximum diameter of hole of porous media 121 or bundle of capillary tubes 122.So, the irrigation device with water control valve pipe 1 need to only be placed into the soil, water can be uniformly sent to root system of plant without laying water supply line, then regularly replace water container 2 or periodically to the supplement moisture content of water container 2.
