Known crops drip irrigation is generally utilize plastic conduit that water is about aperture on 10mm hollow billet or water dropper by diameter to deliver to crop root and carry out localized irrigation.It is the most effective a kind of Water Saving Irrigation Mode of current drought and water-scarce area, and the availability of its water can reach 95%.Drip irrigation system is primarily of head pivot, pipeline and drip head three part composition, and pipeline wherein and drip head often produce negative pressure and aspirated foreign body due to water flow pressure fluctuation, cause pipeline blockage.There is the drip head that minority has anti-back suction function on the market at present, but often complex structure, difficulty of processing causes greatly price general higher.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome above-mentioned middle Problems existing, provide a kind of anti-suck drip irrigation flow control valve for irrigation and water conservancy, it is rational in infrastructure, there is the advantage that structure is simple, easy to use, anti-suck is effective, clever lightness is high, effectively solve the problem of dropper system suck-back blocking pipeline.
The utility model solves the technical scheme that its technical problem adopts: a kind of anti-suck drip irrigation flow control valve for irrigation and water conservancy, comprise interconnective water inlet, adjustable side and water side successively, described water inlet inside is provided with step-like inlet opening; Described inside, water side is provided with apopore;
The two ends of described adjustable side spin with the mutual screw thread of water inlet and water side respectively; Inside, described adjustable side is provided with some back shafts that the cavity that is communicated with inlet opening and apopore and radial direction are fixedly installed on cavity inner wall; Be provided with the sleeve of opening towards inlet opening in the middle part of described back shaft, sliding in sleeve is provided with for adjust flux and the conical plug preventing suck-back.
As preferred scheme, described conical plug comprises taper chock plug that rubber makes and and the axle of the mutual matched in clearance of sleeve.
As preferred scheme, the connecting portion of described water inlet and water side and adjustable side is respectively arranged with the nut for locking adjustable side.
As preferred scheme, described surface, adjustable side is provided with anti-slip tank.
The beneficial effects of the utility model are: a kind of anti-suck drip irrigation flow control valve for irrigation and water conservancy, and adopt the three section type design of water inlet, adjustable side and water side, wherein water inlet and water side are connected with water pump and branch's dropper respectively; Adjustable side inner chamber is provided with the sleeve of opening towards water inlet, is socketed with conical plug in sleeve, and when hydraulic pressure is normal, conical plug is headed in sleeve, and current pass through, and during generation negative pressure, conical plug is sucked out and abuts with water inlet, blocks the generation of negative pressure; Flow control valve combines with anti-back suction function by the utility model, and eliminate the special high cost buying anti-back suction function drip head, the installation and debugging time also can significantly shorten; It is rational in infrastructure, has the advantage that structure is simple, easy to use, anti-suck is effective, clever lightness is high, effectively solves the problem of dropper system suck-back blocking pipeline.
