초록 ▼

A device and method, especially adapted for operating sprinklers, shower heads etc. at low flow, converts low continuous liquid flow to a high intermittent and pulsating flow. The liquid is introduced at a controlled low rate of flow, such as by the use of a pressure-compensated dripper in a liquid supply line. The liquid then flows into a chamber which is somewhat expandable in volume. The pressure increases in the chamber while outflow of the liquid is restricted until pressure created by introduction of the liquid is sufficient to eject the fluid intermittently at a higher flow. This is achieved by utilizing a pressure-responsive valve in the liquid exit of the container. The valve has a preset pressure response designed for quick response to create a water hammer effect. The valve has openings which create a pumping effect to admix air or another liquid with the effluent stream. Sprinklers, shower heads, or any other spraying devices connected to this pulsator will spray liquids to a large designated area with only a very small fluid flow. A drip line connected to such a device may have very large openings, yet the flow through each such dripper can be very large. A preferred form of the pulsator is a pulsating valve in which the receptacle container and the other required elements for such a pulsating device are part of the valve itself.

A method for converting a continuous fluid flow at a low rate of flow to high intermittent pulsating flow at a high rate of flow, comprising: (a) supplying fluid at a low controlled flow rate into a receptacle having a relatively low elasticity, said receptacle having an integral fluid inlet means and an integral fluid outlet means; (b) establishing a body of said fluid under pressure in said receptacle; (c) said integral fluid outlet means of said receptacle preventing outflow of said fluid from said receptacle until a predetermined pressure is achieved in said receptacle; (d) said outlet means of said receptacle allowing said fluid to flow out from said receptacle through a resistance so as to force the pressure within said receptacle to increase and force said outlet means to become widely open; (e) ejecting said fluid from said receptacle and through said resistance at a high rate of flow as a pulse while fluid continues to flow into said receptacle at said low controlled flow rate and, by ejecting said fluid, causing the pressure and the volume of fluid within said receptacle to decrease and allowing said outlet means to close and terminate one pulsating cycle, (f) said supplying fluid being done with a liquid fluid, (g) supplying said liquid at a constant continuous controlled rate to said receptacle and allowing said liquid to flow out of said receptacle through said outlet means until said pressure in said receptacle is diminished to a predetermined level, (h) at the same time (1) restricting said outflow sufficiently to create a water hammer effect to generate a high pressure liquid pulse, and (2) quickly discontinuing emission of liquid until said pressure within said receptacle is again increased to said predetermined level, and (i) repeating said sequence continuously for a desired period of time to produce said high intermittent pulsating flow.
