Fluid flow control device and fluid distribution system including a plurality of such devices

Abstract

A fluid-flow control device comprises a fluid coupling having an inlet connectable to a supply line, an outlet connectable to an outlet device, a flow-deviating member having two taps connected by a quickly attachable and detachable tube disposed externally of the control device through which the fluid is constrained to flow from the coupling inlet to the coupling outlet, the external tube, the flexible tube having a predetermined length, substantially greater than the distance between the taps, to thereby cause a predetermined pressure drop in the fluid flowing therethrough from the coupling inlet to its outlet. Also described is a fluid distribution system including a plurality of the above fluid-flow control devices connected to a fluid supply line, the tubes connected between the two taps in the fluid couplings being of differing predetermined lengths to provide a substantially uniform outlet pressure of flow rate to the outlet devices along the line from the upstream end to the downstream end of the line.
