Description
Technical field
The utility model relates to a kind of rotary drip irrigation emitter preventing blocking, and particularly relates to a kind of stainless steel wire rotated in pore that utilizes and prevents the drip irrigation emitter blocked.
Background technology
The mode of current domestic common drip irrigation emitter many employings tubular type decompression current limliting, the mode etc. of labyrinth type turbulent flow flow channel type decompression current limliting.With upper type because the existence of impurities in water and microorganism makes drip irrigation emitter easily block.Become the subject matter of drip irrigation, infiltrating irrigation, Micro-Irrigation Development, and be eager to solve.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary drip irrigation emitter preventing blocking, utilize the hydraulic pressure energy of original irrigation water to be prevented the drip irrigation emitter blocked by vane pump (or gear pump, plunger pump etc.) stainless steel wire rotated in pore, solve the susceptible to plugging problem of existing drip irrigation emitter.
Technical solution of the present utility model:
The rotary drip irrigation emitter preventing blocking, its special feature is:
Comprise water dropper shell, water dropper water inlet, decompression water inlet, stainless steel wire, drip fast set screw, vane pump circulator, water dropper delivery port;
Described water dropper water inlet and water dropper delivery port are separately positioned on the two ends up and down of water dropper shell;
Relief chamber, backwater cavity, pump chamber and water chamber is divided into successively from top to bottom in described water dropper shell;
Described water dropper water inlet is arranged on the upper end of relief chamber, and the lower end of relief chamber is communicated with backwater cavity by decompression water inlet;
Described vane pump circulator comprises vane pump, and described vane pump is arranged on also can around vertical axis revolving in pump chamber; The water inlet of described vane pump communicates with backwater cavity; The delivery port of described vane pump communicates with water chamber;
Described fast set screw is arranged on water dropper delivery port;
Described stainless steel wire upper end is stretched in relief chamber, and its lower end and vane pump vertical axis are connected;
Described stainless steel wire and water inlet decentraction.
The high-pressure side of described vane pump communicates with backwater cavity as the water inlet of vane pump; The low-pressure end of described vane pump communicates with water chamber as the delivery port of vane pump.
The internal diameter of described delivery port is much larger than the internal diameter of water inlet.
Described vane pump circulator can also adopt gear pump or plunger pump.
The advantage that the utility model has is:
1, the utility model is the same with the water dropper mounting means originally used, without the need to special material and technology.The speed that fast set screw can change water dropper is within the specific limits dripped by regulating.
2, because water dropper should not block the inspection and replacing that can reduce water dropper.
3, the utility model can extensive use agricultural irrigation, plant equipment long-term low flow velocity lubricating system (changing water into lubricating oil) etc.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1-water dropper water inlet, 2-reduces pressure water inlet, and 3-pump water inlet mouth, 4-vane pump circulator, 5-pumps the mouth of a river, 6-water dropper delivery port, and 7-drips fast set screw, 8-stainless steel wire.
Embodiment
The rotary drip irrigation emitter preventing blocking, comprises water dropper shell, water dropper water inlet 1, decompression water inlet 2, stainless steel wire 8, drips fast set screw 7, vane pump circulator 4, water dropper delivery port 6; Water dropper water inlet 1 and water dropper delivery port 6 are separately positioned on the two ends up and down of water dropper shell; Relief chamber, backwater cavity, pump chamber and water chamber is divided into successively from top to bottom in water dropper shell; Water dropper water inlet 1 is arranged on the upper end of relief chamber, and the lower end of relief chamber is communicated with backwater cavity by decompression water inlet; Vane pump circulator 4 comprises vane pump, and vane pump is arranged on also can around vertical axis revolving in pump chamber; Dripping fast set screw 7 is arranged on water dropper delivery port 6; Stainless steel wire 8 upper end is stretched in relief chamber, and its lower end and vane pump vertical axis are connected; Stainless steel wire 8 and water inlet decentraction.The high-pressure side of vane pump communicates with backwater cavity as vane pump water inlet 3; The low-pressure end of vane pump communicates with water chamber as vane pump delivery port 5.The internal diameter of delivery port is much larger than the internal diameter of water inlet.
The principle of the invention:
Vane pump can rotate in water dropper housing, and is rotated together by the stainless steel wire disclosed into water inlet be connected in rotating shaft.Stainless pin rotates in the pore of water inlet with vane pump, due to stainless steel wire and water inlet decentraction, has certain swing, foreign material, sand etc. are pushed away water inlet during rotation, block to avoid water inlet.
Because delivery port in delivery port is much larger than water inlet, form certain pressure reduction at the two ends of vane pump, drip vane rotary when speed is greater than the internal leakage of vane pump when water dropper.
Current limliting water inlet due to Cross section Design little of water inlet, thus limits water dropper water yield.
Drip fast set screw carrys out a regulating dropping head speed by the sectional area of regulating dropping head delivery port.
