Specific embodiment
Farmland intellectuality irrigation management system includes farmland 1, irrigation pumping station 2, water delivery supervisor 3, irrigates branch pipe 4, irrigates
Outlet pipe 5, control device for irrigating 6 and agricultural land soil watch-dog 7.Interval shape is embedded with multiple irrigation branch side by side for agricultural land soil lower section
Pipe 4, it is 100 meters to irrigate the spacing between branch pipe 4, and the length for irrigating branch pipe 4 is more than 1000 meters.Irrigation branch pipe 4 one end is provided with defeated
Water supervisor 3, water delivery supervisor 3 connects with irrigation pumping station 2 and multiple branch pipes 4 of irrigating.
Air inlet and exhaust valve 9, safety valve 10 are disposed with irrigation pumping station 2 and the water delivery supervisor 3 irrigated between branch pipe 4, adjust
Pressure valve 11, check-valves 12 and drain valve 13.The master of air inlet and exhaust valve 9, safety valve 10, pressure regulator valve 11, check-valves 12 and drain valve 13
It is respectively destruction pipeline vacuum to act on, and excludes inner air tube, reduces resistance of water conveyance, and overpressure protection adjusts pressure, prevents pipeline
Interior water passes back into water source and causes water pump high speed reverse rotation.
Air inlet and exhaust valve 9 by valve flap structure be divided into ball-valve type, it is flat enter the major class of (row) air valve two.Its operation principle is pipeline
During water-filling, gas rises from the discharge of (row) gas port, ball (flat board) valve is entered by the buoyancy of water in pipe, is closed under internal water pressure effect
Enter (row) gas port, make non-leakage into (row) air valve sealing, exhaust process is finished.Pipeline stop supply water when, ball (flat board) valve because
Siphonage falls with conducting oneself with dignity, and leaves ball (flat board) mouth, and air enters pipeline, destroys pipeline vacuum or makes the backflow of pipeline water
Interrupt, it is to avoid the water pump high speed reverse rotation that pipeline vacuum is destroyed or the backflow because managing interior water causes.
Safety valve 10 is a kind of pressure relief device, installed in pipeline lower, plays overpressure protection.Low pressure pipeline is filled
Irrigating the safety valve commonly used in system can be divided into spring, lever and weight type by its structure type.
The operation principle of safety valve 10 is to load on flap the weight of spring force or weight to control, adjust to open pressure
Power (i.e. set-pressure).When pipe-line system pressure is less than set-pressure, safety valve sealed reliable, ne-leakage phenomenon；Work as pipeline
System pressure is raised and during more than set-pressure, and valve then automatically turns on draining immediately, declines pressure；When pipe-line system pressure
It is reduced to when below set-pressure, valve is closing and sealing off as before in time.
Safety valve 10 should determine the nominal pressure of safety valve when selecting according to the design work pressure of protected pipeline.
Its range of regulation is determined by the level pressure value for calculating, the discharge outlet diameter of safety valve is calculated according to pipeline maximum stream flow, and
The Opening pressure of valve has been revised before installation.Spring, lever and weight safety valve are applied to low pressure pipeline irrigation system.
The general vertical of safety valve is arranged on the stem of pipe-line system, and operator is easily observed that, and is easy to check, repairs,
Also the position of any required protection in pipe-line system can be arranged on.
