Abstract
The utility model relates to a pressure-compensation snap-fastener dropper which is used for water-saving irrigation. The pressure-compensation snap-fastener 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 connected; the end surface of the water feeding seat is provided with a filter screen; a runner body is arranged in the water discharging seat; the runner body is characterized in that two round tubes with different diameters are sheathed coaxially, a runner is formed between two round tubes, and the outer round tube is higher than the inner round tube; the top ends of two round tubes of the runner body are respectively provided with a notch, and two notches form an angle of 180 degrees; the runner on the runner body is communicated with the water feeding seat and the water discharging seat; and the top end of the runner body is covered with an elastic compensation diaphragm. When pressure fluctuates, the elastic compensation diaphragm floats between the water feeding seat and the water discharging seat to regulate water feeding amount, the runner formed by the runner body increases the flow of water, and buffers the pressure fluctuation and realizes the effects of balancing the pressure fluctuation and balancing dropper flow quantity.
Description
Technical field
The utility model relates to the pressure-compensated snap-fastener water dropper that a kind of water-saving irrigation is used.
Background technology
Water-saving irrigation system constitutes pipe network by the tubing and the connector of different size, waters crop at the pipe network end by water dropper, and the performance of anti-blockage of water dropper directly influences the operation of whole pipe network.Because pressure compensating emitter can remedy the pressure differential that the physical features gradient brings, guarantee the uniformity of water dropper flow, so use this pressure compensating emitter in fruit tree drip irrigation and the green barren hill mostly.The pressure compensating emitter that uses all is the douche form at present, Chinese patent CN00215221.5 has announced the compensation water dropper of a kind of anti-retaining pressure, it 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, on the cone face, establish straight-through fan-shaped runner.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.
Summary of the invention
The purpose of this utility model provides a kind of water outlet good uniformity, the pressure-compensated snap-fastener water dropper that performance of anti-blockage is strong.
The scheme that the utility model technical solution problem is adopted is:
A kind of pressure-compensated snap-fastener water dropper, it comprises hollow water-logged base and " protruding " font effluent seat of a frustum, water-logged base links to each other with effluent seat, the water-logged base end face is provided with filter screen, be provided with a runner body in the effluent seat, runner on the runner body communicates with water-logged base and effluent seat, and runner body top covers an elastic compensating diaphragm.
Above-mentioned pressure-compensated snap-fastener water dropper, runner body in its effluent seat be the pipe of two reducings coaxial be nested and the two between form runner, the pipe of outside is higher than the pipe of the inside, two pipe tops of runner body are respectively equipped with a breach, two breach are 180 ° mutually, this structure plays the effect of anti-negative pressure, has guaranteed the smooth and easy operation of dripping.
Above-mentioned pressure-compensated snap-fastener water dropper, 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, water-logged base is enclosed within outside the effluent seat, tubing can block water dropper when the small that the diameter difference forms can be guaranteed to install, and prevented that water dropper from coming off.
Above-mentioned pressure-compensated snap-fastener water dropper, the apopore of its effluent seat are positioned at the effluent seat side and communicate with runner body runner, and water yield is more stable, and the filter screen of water-logged base is shaped as rectangle, trapezoidal, oval, waveform, annular or radial.
Above-mentioned pressure-compensated snap-fastener water dropper is provided with annular boss or groove in its water-logged base connector, 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 and convenient.
Above-mentioned pressure-compensated snap-fastener water dropper, its water-logged base connector form by being threaded with effluent seat and removably connect, and it is more firm to be threaded, difficult drop-off.
Above-mentioned pressure-compensated snap-fastener water dropper, its water-logged base connector and effluent seat are connected firmly for fixedlying connected, and have stopped to leak.
The beneficial effects of the utility model are: pressure-compensated snap-fastener water dropper comprises a frustum hollow water-logged base, " protruding " font effluent seat, water-logged base is connected with effluent seat, the water-logged base end face is provided with filter screen, effluent seat is provided with a runner body, runner body runner communicates with water-logged base and effluent seat, covers an elastic compensating diaphragm on the runner body.Water enters water dropper by the filter screen on the water-logged base end face, gap through runner body and elastic compensating diaphragm enters runner body runner, ooze from the apopore of effluent seat, the elastic compensating membrane covered is on the runner body, when in the drip irrigation process, water pressure fluctuations occurring, rely on differential water pressures, the elastic compensating diaphragm floats between water-logged base and effluent seat, regulate inflow, the runner body of effluent seat is that the pipe of two reducings is nested and forms runner, and current enter runner by two breach that are 180 ° mutually, the runner body plays the effect of compensator or trimmer pressure, help guaranteeing the water outlet uniformity, two breach of runner body have played the effect of anti-negative pressure, guarantee to drip smoothly operation.Water enters water dropper by the filter screen of water-logged base, with impurity filtering in the water, improves the performance of anti-blockage of water dropper.This pressure-compensated snap-fastener water dropper is directly installed on the water inlet pipe when using, and is easy to use.
