Abstract
The utility model relates to an irrigation flow control valve for an irrigation system, which comprises a valve body, wherein, a water inflow pipe and a water outflow pipe are arranged on the valve body, and the connection of the water inflow pipe and the water outflow pipe is provided with a floating ball valve and a quantitative water tank. A dripper and a water tank are arranged on the water outflow pipe, the two water tanks are communicated via a siphon, and the bottom of the quantitative water tank is provided with a unidirectional drainage pipe. The device completes the automatic control to irrigation flow through the irrigation flow control valve by means of the action of water pressure.
Description
The utility model relates to agricultural irrigation, can especially be useful in the automaton of the quantitative water of water-saving irrigation greening thing in the highway median strip as the automaton of the quantitative water of crop irrigation.
The particularity of highway makes that the irrigation and the farming work of greening thing are all very heavy on the highway, adopt the waterwheel broad irrigation at present, this mode not only drops into height, also can cause highway distress, more serious is to influence traffic safety, to highway administration, workmen's safety also causes very big threat.Drip irrigation is that system was transported to water dropper by low pressure pipeline, then solution evenly and is lentamente splashed into the new technology in plant roots district after water was pressurizeed, filters together with fertilizer, agricultural chemicals, chemical hormone.It is used in have significant safe, efficient, water saving on the highway, advantage such as energy-conservation.But the automation equipment more complicated of present drip irrigation, to use measurement, monitoring instrument in a large number, as soil moisture sensor, pipeline flow sensor, magnetic valve etc., couple together by cable then, at central control system the information that monitors is carried out overall situation control, invest quite highly, can't popularize use.
The purpose of this utility model provides the irrigation flow control valve in a kind of irrigation system, relies on the effect of hydraulic pressure in the pipeline, finishes irrigating the automatic control of flow by irrigating the flow control valve I.
This purpose realizes with following technical proposal: irrigate the flow control valve I and be provided with oral siphon 1, outlet pipe 2 on casing, be provided with ball-cock assembly 3 in its junction, be provided with quantitative water tank 4 near ball-cock assembly, outlet pipe 2 is connected with water outlet water dropper 5 by hollow billet 16, the water dropper below is provided with water tank 6, it is communicated with quantitative water tank 4 by siphon pipe 7, is provided with drainpipe 8 in quantitative water tank 4 bottoms, is provided with check valve 9 in the draining mouth of pipe.
The utility model is by irrigating the flow control valve I irrigation system flow to be controlled automatically.It is applicable to agricultural irrigation systems, especially can demonstrate its superior function especially in highway automatic water-saving irrigation system.Can reduce system's transmitting power, reduce requirement, reduce engineering cost, can make the irrigation of highway water saving reach automation again the compression strength of tubing.This control device need not be manually or electric operating.It is rational in infrastructure, and start or stop is reliable, and is with low cost, has the very strong ability of promoting the use of.
Following accompanying drawing has provided enforcement legend of the present utility model:
Fig. 1 is the utility model overall structure and pipeline connection diagram.
Fig. 2 is for irrigating the interior connection diagram of flow control valve I.
Fig. 3 is that the A-A of Fig. 2 is to cut-away view.
Below in conjunction with accompanying drawing overall structure of the present utility model and operation principle thereof are done further explanation:
As shown in Figure 2: irrigate the flow control valve I, side on its casing 8 is provided with an oral siphon 1, its opposite side has outlet pipe 2, oral siphon communicates with outlet pipe, be provided with a ball-cock assembly 3 in its junction, be provided with quantitative water tank 4 near ball-cock assembly, the ball-cock assembly valve body is separated by with quantitative water tank.Described ball-cock assembly 3 is provided with flap 14 within it by valve body 13, is connected with gangbar 15 with flap, gangbar top and the floating ball rod formation of joining.Ball float 12 places in the quantitative water tank 4, sees Fig. 3, is equipped with water outlet water dropper 5 by capillary 16 and at its top on outlet pipe 2.See Fig. 2, device has water tank 6 below water dropper 5, and it communicates with quantitative water tank 4 by siphon pipe 7.Bottom at quantitative water tank 4 is provided with drainpipe 8, sees Fig. 1, and the drainpipe 8 of irrigating in the flow control valve I is communicated with water inlet pipe 1, and check valve 9 is housed on the drainpipe.Water tank 6 and ball-cock assembly 3 are respectively by being bolted on the casing 10.Ventilation hole 11 communicates with atmosphere.
The operation principle of the irrigation volume control device in this irrigation system:
Irrigate the operation principle of flow control valve I: referring to Fig. 1,2,3.Water enters the oral siphon 1 of irrigating the flow control valve I through the trunk line II, and this oral siphon 1 is communicated with drainpipe 8, when water enters water pipe 1, also flows into drainpipe 8, and promotes the flap of check valve 9, makes it seal the bottom of quantitative water tank 4.And water enters outlet pipe 2 and capillary 16 from oral siphon 11 respectively by the ball-cock assembly of opening 3.At this moment irrigating water in the outlet pipe 2 of flow control valve I flows in the hollow billet of irrigated area and has irrigated plant.The water that flows into capillary 16 simultaneously enters water tank 6 by water dropper 5, and the water of water tank 6 flows into quantitative water tank 4 through siphon pipe 7 after reaching a constant volume.Determine the liquid level of quantitative water tank 4 according to the duty of plant needs.When the water that flows into 4 li in water tank reached design height, ball float 6 moved down by the gangbar 15 that leverage promotes in the ball-cock assembly 3, and withstood flap 14 and tightly be pressed on the flap seat 17, and closed oral siphon 1, blocked current.
After water pump quit work, the water of irrigating in the water tank 4 in the flow control valve I flowed into trunk line, discharged by the delivery port of system's minimum point.Ball float 12 is opened the ball-cock assembly of closing under the effect of gravity, return to the state before irrigating.
