Abstract

A T-shaped flow divider for use in watering and irrigating systems, with a swivel inflow connector, and a four-position three-hole ball control valve to direct the outflow to one or other or both of the T-arm outflow connectors, or to close off flow completely. The swivel feature permits the outflow connectors to swivel to any convenient circumferential location while the inflow connector is attached to a water supply source. This obviates the need for complete dismantling of rigid systems with 2-way valves for maintenance or changes in the system. Further, the 4-way control valve permits the accurate design of extended irrigation systems, particularly for irregular areas. One version of the flow divider has female threads on the swivel inlet flow connector for attaching to hose bibs and the like, with male threads on the outflow connectors.

Claims

1. A flow divider for use in watering and irrigation systems, attachable to a water supply source, said flow divider comprising:

a swivel inlet flow connector attachable to a water supply source;

a multi-position control valve attached to and receiving flow from said swivel inlet flow connector; and

a number of outflow connectors attached to and selectively receiving flow from said multi-position control valve;

whereby said outflow connectors may be swiveled to any convenient circumferential position around said swivel inlet flow connector during attachment of said swivel inlet flow connector to said water supply source, and water from said water supply source is distributed to selected outflow connectors by suitable positioning of said multi-position valve.

2. The flow divider according to claim 1 further made of metal.

3. The flow divider according to claim 1 further made of plastic.

4. The flow divider according to claim 1 wherein the swivel inlet flow connector and the number of outflow connectors have circular cross-sections.

5. The flow divider according to claim 1 wherein said swivel inlet flow connector has a female thread for attaching to a water supply source with a male thread.

6. The flow divider according to claim 1 wherein said number of outflow connectors have male threads for attaching to components of watering and irrigation systems with female threads.

7. The flow divider according to claim 1 wherein the number of outflow connectors is two, namely a right outflow connector and a left outflow connector on either side of said control valve, with flow in said outflow connectors in linearly opposed directions, further with said swivel inlet flow connector attached to said control valve in a direction perpendicular to said linearly opposed outflow connectors so that said flow divider assumes a T-shape with said control valve at the central T-junction.

8. The flow divider according to claim 7 wherein said control valve is a three-hole ball valve which can be rotated about an axis perpendicular to the plane of said swivel inlet flow connector and said outflow connectors to assume four positions 90 degrees apart to control flow from said swivel inlet flow connector to the right and left outflow connectors, said positions, respectively, (1) ducting flow to the right outflow connector, (2) to the left outflow connector,(3) to both the right and the left outflow connectors, and (4) closing off flow totally, thereby providing a variety of possibilities for the design of extended watering and irrigation systems which employ a plurality of said T-shaped flow dividers.

9. The flow divider according to claim 8 wherein further the three-hole ball valve is actuated by a selector handle attached to said valve, the correct placement of the handle to achieve a desired valve position being aided by indicia placed on the exterior of the flow divider.
