Abstract
The utility model relates to a pressure-compensation dropper with high anti-blocking performance, which is used for water-saving irrigation. The pressure-compensation dropper comprises a frustum-shaped hollow water feeding seat and a water discharging seat in the shape of a Chinese character ''Tu'', wherein the water feeding seat and the water discharging seat are detachably connected; the end surface of the water feeding seat is provided with a filter screen; a columnar mandrel holder is arranged in the water discharging seat; the surface of the columnar mandrel holder is provided with a maze runner; an elastic compensation casing pipe is sheathed on the exterior of the columnar mandrel holder; two ends of the maze runner are respectively communicated with the water feeding seat and the water discharging seat; and water flows into the dropper from the filter screen of the end surface of the water feeding seat and enters the water outlet of the water discharging seat from the maze runner on the surface of the columnar mandrel holder. When water inflow pressure fluctuates, the maze runner has the action on buffering pressure, meanwhile the outer surface of the elastic compensation casing pipe is subjected to varied pressure, so that distance between the elastic compensation casing pipe and the maze runner of the columnar mandrel holder becomes big or small, water flowing amount is increased or decreased correspondingly, and the pressure-compensation dropper performs the action on compensating pressure fluctuation and guaranteeing even water discharge.
Description
Technical field
The utility model relates to a kind of water-saving irrigation and blocks up pressure compensating emitter with high resisting.
Background technology
At present, drip irrigation is much all used in orchard, green house of vegetables and urban afforestation, drip irrigation system is made of tubing, connector and the water dropper of different size, water dropper is a water outlet equipment important in the drip irrigation system, in order to remedy the pressure differential that the physical features gradient brings, guarantee the uniformity of irrigation water appilcation of water dropper, select pressure compensating emitter usually for use.Chinese patent CN00215221.5 has announced the compensation water dropper of a kind of anti-retaining pressure, is made of water inlet base, water outlet base, runner body, elastic compensating sheet, it is characterized in that runner body medial surface is the cone face, establishes straight-through fan-shaped runner on the cone face.Because straight-through fan-shaped runner directly communicates with water inlet, water outlet, runner is unimpeded, and less by the sectional area of elastic compensating sheet adjusting, so the shortcoming of this structure is that pressure compensation performance and performance of anti-blockage are poor, must cause the water outlet uniformity relatively poor.

The anti-stifled pressure compensating emitter of above-mentioned height, its water-logged base one end inner surface is provided with annular boss or groove, and the effluent seat outer surface is provided with the groove or the boss formation that cooperate with water-logged base and removably connects, and this connected mode is simple in structure, easy for installation.
The anti-stifled pressure compensating emitter of above-mentioned height, its water-logged base is connected to form by screw thread and effluent seat and removably connects, and thisly is threaded more firmly, is difficult for disengagement.
The anti-stifled pressure compensating emitter of above-mentioned height, one end of its water-logged base prolongs and forms cylindrical connector, the diameter of connector is less than the outside diameter of water-logged base frustum, effluent seat is enclosed within outside the water-logged base connector, the effluent seat end diameter is less than the outside diameter of water-logged base frustum, the sunk part that water-logged base and effluent seat junction difference in size form blocks tubing when being used to install, and prevents that the effect that water dropper is under pressure from coming off.
The anti-stifled pressure compensating emitter of above-mentioned height, its water-logged base connector surface is provided with annular boss or groove, and effluent seat is provided with the groove or the boss formation that cooperate with the water-logged base connector and removably connects, and this connected mode is simple in structure, and is quick and easy for installation.
The anti-stifled pressure compensating emitter of above-mentioned height, its water-logged base connector is connected to form by screw thread and effluent seat and removably connects, and thisly is threaded more firmly, is difficult for disengagement.
The anti-stifled pressure compensating emitter of above-mentioned height, the termination of the bossing of its effluent seat is that frustum and its bus overlap with water-logged base frustum bus, bus overlaps when installing and is easier to throw water dropper into tubing, and the tubing wall is stuck in the thin part of effluent seat, anticreep best results.
The anti-stifled pressure compensating emitter of above-mentioned height, its delivery port is positioned at the effluent seat side, and effluent seat inside center position is provided with the installing hole of column core print seat, and installing hole communicates with delivery port.Delivery port is positioned at the effluent seat side, is positioned at bottom centre than delivery port in the prior art and directly communicates with runner, and the uniformity of dripping is better.
The anti-stifled pressure compensating emitter of above-mentioned height, the filter screen shape of its water-logged base are rectangle, trapezoidal, oval, waveform, annular or radial, labyrinth flow-path be shaped as " S " type or rectangle, simple in structure, easy processing.
The anti-stifled pressure compensating emitter of above-mentioned height, its labyrinth flow-path is looped around column core print seat outer surface or has two labyrinth flow-paths at least and column core print seat axis is arranged in parallel at column core print seat outer surface, around the labyrinth flow-path long flow path, the buffering effect of pressure oscillation is better, in line labyrinth flow-path can be provided with different quantity, flow range of choice broad according to the difference of traffic demand.
The beneficial effects of the utility model are: the utility model is that the hollow water-logged base of a frustum is connected with " protruding " font effluent seat, the water-logged base end face is provided with filter screen, the effluent seat bottom centre position is provided with the column core print seat, column core print seat surface is provided with labyrinth flow-path, the flexible compensating jacket of column core print seat overcoat, the two ends of labyrinth flow-path communicate with water-logged base and effluent seat respectively.Water enters water dropper by the filter screen of water-logged base, enters delivery port through the labyrinth flow-path between column core print seat and elastic compensating sleeve pipe then, drips to crop root at last.The filter screen of water-logged base plays a role in filtering, and has guaranteed the performance of anti-blockage of water dropper, and labyrinth flow-path has the effect of compensator or trimmer pressure, again in conjunction with the compensate function of elastic compensating sleeve pipe, has guaranteed that the water outlet of water dropper is even.The utility model water outlet good uniformity, performance of anti-blockage are strong on the whole.
