Rear end at valve body is provided with gland, and gland and valve body be by being threaded, and is provided with the pressing plate that is slidingly matched with body cavity at the inner face of gland, and pressing plate is provided with sealing ring; The two ends of spring are connected with pressing plate with piston respectively; Front end at valve body is provided with end cap, and described water inlet is the long tube that is fixed on the end cap, and the rear portion of long tube is positioned at the inner chamber of valve body, and end face contacts with piston thereafter; Delivery port is positioned on the valve body in piston the place ahead.
Front end at valve body is provided with gland, and gland and valve body are provided with sealing ring by being threaded between gland and valve body; The front end face of described piston is provided with the circular boss that matches with body cavity, and the outer round surface of boss contacts with water inlet; The two ends of spring are connected with piston with gland respectively.
On piston, be respectively arranged with sealing ring, be respectively arranged with sealing gasket in the contact site of piston and water inlet.
Because this device has adopted the potter's clay water core of water filling to respond to the flow of water of soil, the negative pressure control piston that relies on soil water potential to lower and produce moves and makes valve open, after soil water potential raises, rely on spring tension that piston reset is closed valve automatically, thereby reach the purpose that does not need other energy to realize automatic water-supply.This apparatus structure is simple, with low cost, can arbitrarily lay inductor according to the target of required monitoring, the irrigation range that each water supply installation is controlled is also changeable, can irrigate according to the water requirements of kind of plant in good time, both saved the energy, reduced waste again, greatly reduced operating cost water resource, to farming, herd, forestry all has broad application prospects.

Embodiment
Embodiment 1: this intelligent soil water supply device comprises valve and the inductor that is connected with valve, inductor is made up of with the base 12 of fixedlying connected with potter's clay water core potter's clay water core 13, be provided with cavity in inductor inside, base 12 is provided with water filling port 1 and the sensing hole 15 that is connected with cavity, and sensing hole 15 is connected with valve by tube connector 2.Described valve comprises valve body 16 and is arranged on the spring 8 and the piston 3 of body cavity, is provided with water inlet 5 and delivery port 6 at the front end of valve body 16, and when valve closing, piston 3 contacts with water inlet 5.Be provided with gland 10 in the rear end of valve body 16, be provided with the pressing plate 9 that is slidingly matched with body cavity at the inner face of gland 10, gland 10 and valve body 16 are by being threaded.The effect of gland 10 is by screwing or unclamping screw thread pressing plate 9 to be moved, thereby the pressure of spring 8 is regulated.The two ends of spring 8 are separately fixed on piston 3 and the pressing plate 9 corresponding end faces.In order to process with easy for installation, also be provided with end cap 4 at the front end of valve body 16, in the present embodiment, described water inlet 5 is the long tubes that are fixed on the end cap 4, the rear portion of long tube is positioned at the inner chamber of valve body 16, and end face contacts with piston 3 thereafter; In order to guarantee that smooth water outlet, delivery port 6 are positioned on the valve body in piston 3 the place aheads when the valve opening, promptly when piston 3 is in the limiting condition of valve closing, still can not contact with delivery port 6.Sensing hole 15 on the inductor is connected with pressure chamber 14 on the valve by tube connector 2, and the negative pressure that soil water potential is produced arrives pressure chambers 14 through tube connector 2, the moving of control piston 3.In order to realize sealing, be provided with sealing ring 11 at the matching part of piston 3 and body cavity, on pressing plate 9, also be provided with sealing ring 11; Contact site at piston 3 and water inlet 5 is provided with sealing gasket 7.
Embodiment 2: pressure chamber 14 is arranged between the rear end face of piston 3 and valve body 16; Front end at valve body 16 is provided with gland 10, and gland 10 and valve body 16 are provided with sealing ring 11 by being threaded between gland 10 and valve body.The front end face of described piston 3 is provided with the circular boss that matches with valve body 16 inner chambers, and the outer round surface of boss contacts with water inlet 5 during valve closing.The two ends of spring 8 are separately fixed on the end face of gland 10 and piston 3.Other structure of embodiment 2 is identical with embodiment 1.
In addition, also can on the gland 10 of embodiment 2, pressing plate be set, the two ends of spring 8 are separately fixed on pressing plate and the piston end face.
Can also be according to the pressure limit of soil water potential, select the valve of the band pressure chamber of other version composition automatic water supply device that is connected with inductor.
Its operation principle is: on the potter's clay water core wall on the inductor many tiny holes are arranged, before the use, by water filling port 1 the inductor inner chamber is injected water earlier.Potter's clay water core 13 can be full of water by behind the water infiltration in hole, when inductor was inserted the moisture unsaturated soil, the water in the hole just coupled together with the soil water.When soil water potential is between 0～0.8 atmospheric pressure, tiny hole on the potter's clay water core wall can only can not pass through gas by liquid, therefore, if soil water potential reduces, the flow of water that potter's clay water in-core is stored also reduces with extraneous soil water potential and reaches balance, form negative pressure at the inductor inner chamber, then make the sealing load chamber 14 in the valve produce negative pressure by tube connector 2, when the pulling force of negative pressure generation surpasses the pressure of spring generation, the pulling force that is produced by negative pressure moves piston 3 backward, thereby the water inlet on the valve 5 is opened realization to soil water supply.Otherwise when the soil moisture increase, after the flow of water raise, negative pressure reduced, and the pulling force that negative pressure produces reduces, and then the tension force of spring 8 makes piston reset that valve is closed automatically.
