Abstract:
1. A rod activated water valve with security feature comprising: a valve base, a top end of the valve base being threaded on an outside surface for mating with a standard water faucet thread arrangement, a second end of the valve base having a threaded outside surface; a cylindrical valve housing, a top end of the cylindrical valve housing having a threaded inside surface, the threaded inside surface interfacing with the threaded outside surface of the second end of the valve base, the cylindrical valve housing having an inner diameter and the cylindrical valve housing having an inward protruding lip at a housing bottom end, the cylindrical valve housing having an outer circumferential groove on an outside surface, an edge surface of the cylindrical valve housing distal from the threaded inside surface having at least two key cutouts; a cylindrical outer sleeve, the cylindrical outer sleeve having an inner circumferential groove on an inside surface, the inner circumferential groove corresponding to the outer circumferential groove; a C-shaped spring member springedly held within the outer circumferential groove and held within the inner circumferential groove, rotatably holding the outer sleeve in position over the cylindrical valve housing, thereby preventing removal of the cylindrical outer sleeve from the cylindrical valve housing and allowing free rotation of the cylindrical outer sleeve with respect to the cylindrical valve housing, thereby requiring a tool be inserted into the key cutouts for installation and removal of the rod activated water valve with security feature to/from a faucet; a water flow chamber having a solid cylindrical outer surface, the water flow chamber having a substantially flat foraminous surface at one end, an aperture located substantially central to the flat foraminous surface, a water flow chamber top edge having a lip, the one end of the water flow chamber held within the cylindrical valve housing by the inward protruding lip; a rod having a rod head at one end, the rod passing through the aperture and held in place by the rod base; a valve seat having an upper flow guide, upper valve plate and an upper valve plate o-ring, the upper flow guide having water flow openings, the upper flow guide and upper valve plate held within the water flow chamber, the upper valve plate interfacing within the lip of the water flow chamber, a groove of the upper valve plate fitting within the second end of the valve base, the upper flow guide and the upper valve plate having a valve aperture; a valve stem fitted within the valve aperture, the valve stem having an enlarged end, an angled body and a valve base end; a valve o-ring fitted on the valve stem resting against the enlarged end such that the valve o-ring, the enlarged end of the valve stem and the upper valve plate selectively block a flow of water through the valve aperture; whereas the valve base interfaces with the rod head such that lateral movement of the rod displaces the rod head, thereby pushing upward on the valve base resulting in the valve stem lifting thereby enabling a flow of water between the valve stem and the valve aperture.
