Abstract
The utility model discloses an external plugged type vortex blocking resistant two-way dropping head, which is composed of a plug, a sleeve pipe, an adjusting screw, cushion chambers, etc., wherein, the plug is arranged in the middle part of the sleeve pipe and vertical with the sleeve pipe, and the plug and the sleeve pipe are communicated with each other to form an integral structure; the sleeve pipe is sheathed with the adjusting screw; the out parts of the both ends of the adjusting screw are respectively provided with a cushion chamber; the adjusting screw are symmetrically provided with thread grooves with deep to shallow changing threads from the center to the both ends. The utility model has the advantages of simple structure, simple manufacture technology, high precision, convenient installation and operation, easy flushing, no clogging, no water leaking, two-way dropping simultaneously, and high work efficiency.
Description
The utility model relates to agricultural water conservancy water-saving irrigation drip irrigation appliance, the anti-stifled two-way water dropper of particularly a kind of outside plug type eddy current.
At present, the domestic drip irrigation appliance that generally uses mainly contains interior edge labyrinth type, the button pressure-compensated drip irrigation pipe of Israel, U.S. rain bird TPC type pressure-compensation drip tape micro-nozzle, Beijing green edge internally-inlaid paster dropper, the Yanshan Mountain, Beijing long runner energy dissipation type hair water dropper, the pressure compensating emitter of Laiwu, Shandong etc., these water dropper system supports are carefully reasonable, and irrigation performance is stable, are fit to large-scale irrigation, but auxiliary facility complex structure, investment is big, and cost is higher, and water dropper easily stops up, use inconvenience, the life-span is short.Chinese patent ZL98249425.4 " the adjustable water dropper of anti-clogging " provides a kind of simple in structure, cost is low, water dropper easy to use, but its decompression energy dissipating means are more single, the taste water phenomenon that occurs when water droplet flows out fails to solve, adopt gradient pitch owing to regulate threaded rod, processing worker benefit difficulty is big, and can only unidirectional drip irrigation.
The purpose of this utility model provides a kind of simple in structure, and is easy to use, be difficult for to stop up, and do not grow water, the anti-stifled two-way water dropper of outside plug type eddy current.
The technical scheme that realizes the utility model purpose is:
The anti-stifled two-way water dropper of a kind of outside plug type eddy current, partly form by plug, sleeve pipe, adjusting screw(rod), cushion chamber etc., and the plug that be communicated as one vertical with sleeve pipe established at sleeve pipe middle part, the plug upper end is provided with the inlet opening, the two ends of adjusting screw(rod) is respectively equipped with cushion chamber in suit one adjusting screw(rod) in the sleeve pipe, sleeve pipe.Adjusting screw(rod) is arranged with screw thread ditch screw thread from deep to shallow by middle mind-set two ends, and the screw rod two ends is respectively established a regulating tank.
The utility model is simple in structure, and processing technology is easy, the precision height, and installation, easy to use, easily flushing is not stopped up, and does not grow water, two-way simultaneous drip irrigation, high efficiency.

Fig. 2 is two-way gradual change adjusting screw(rod) schematic diagram
Fig. 3 is the sleeve pipe longitudinal sectional drawing
The utility model is described in further detail below in conjunction with accompanying drawing:
The anti-stifled two-way water dropper of a kind of outside plug type eddy current, partly form by plug 2, sleeve pipe 3, adjusting screw(rod) 4, cushion chamber 5 etc., a plug 2 is established at sleeve pipe 3 middle parts, vertical with sleeve pipe 3 and be communicated as one, suit one adjusting screw(rod) 4 in the sleeve pipe 3, adjusting screw(rod) 4 is provided with screw thread ditch gradual change screw thread 6 from deep to shallow by middle mind-set two ends, and a regulating tank 7 is respectively established at the two ends of adjusting screw(rod) 4; A cushion chamber 5 is respectively established in the outer end of regulating tank 7 in the sleeve pipe 3, and the port of cushion chamber 5 is a delivery port 8.During use plug 2 is inserted on the water source arm, current enter in the sleeve pipe 3 by inlet opening 1, shunt to both sides along the screw thread water channel, gradual change with screw thread, water flow pressure reduces gradually, after current advanced people's cushion chamber 5, the further sudden expansion buffering of current, decompression energy dissipating and cushion chamber tube wall refraction energy dissipating were flowed out by 8 shapes of delivery port that are located at the cushion chamber end at last.Because adopt the rotating vortex water channel, no dead angle makes current scourway at any time, prevention silt, incrusted deposit, blocking dropping head.
