摘要： A fluid hydrant has an outlet with a threaded outer surface, and a backflow preventor is mounted on the inlet of the hydrant. The backflow preventor has an inlet and outlet end. Male hose threads are formed on the exterior of the outlet end of the backflow preventer. Interior female threads are on the inlet end thereof. A bushing adapter is interposed between the inlet end of the backflow preventor and the threaded nozzle of the hydrant with the threads connecting the adapter and the backflow preventor being of a size different than the threads connecting the adapter and the threaded nozzle of the hydrant. The bushing adapter extends over the threaded outer surface of the outlet of the hydrant, and a locking cement between the threaded outer surface of the outlet of the hydrant and the interior female threads on the inlet end of the bushing adapter rigidly fix these threads together. The method permanently affixing a backflow preventor to the threaded outer surface of a hydrant comprises taking a backflow preventor having an inlet end with a threaded interior; threading an adapter between the inlet end of the backflow preventor and the threaded outlet of the hydrant; providing different thread sizes at the interior and exterior surfaces of the adapter, with the threads at the interior surface being compatible with the threads of the nozzle on the hydrant; and placing a locking adhesive between the interior threads of the adapter and the nozzle threads of the hydrant.

摘要： A wall mounted water hydrant has an elongated hollow housing with water inlet and outlet ends, and a center axis; an inlet valve in the housing adjacent to the inlet end, including a valve seat and a valve body; a water outlet port in the housing adjacent to its outlet end; a valve operating rod in the housing with its an inner end secured to the valve body and extending along the center axis to the outlet end of said housing, terminating in an outer end; a handle attached to the rod outer end, which when rotated in one direction closes the valve body against the valve seat, and in the other opposite direction moves the valve body away from the seat, thus allowing pressurized water from the inlet to flow downstream through the housing and outlet port; and a backflow preventor secured to the valve downstream from its seat. The elastomeric backflow preventor has a bell shape comprising a cylindrical body smaller than the interior of the housing and thin flexible side walls extending from the body outwardly and downstream to end in a lip portion which normally engages the interior walls of the housing. The construction of the preventor permits it to deflect toward the axis of the housing when water is flowing in a downstream direction and to engage the interior surface of the housing if backpressure urges water to flow in an upstream direction, thus sealing the valve means against backflow.

摘要： A freeze and contamination resistant hydrant, for controlling fluid flow includes: a vertically elongated conduit having a lower portion adapted for installation underground, the conduit having a lower fluid inlet associated with that lower portion, and an upper fluid outlet, for passing fluid; a valve in the lower portion of the conduit; a plunger, with a stopper of substantially circular horizontal cross-section attached, extending downward through the conduit into the valve for closing and opening the same; an upper drain port in the valve above the stopper drains any fluid trapped above the valve when the valve is closed; a venturi conduit below the valve having a venturi port; and a fluid reservoir surrounding at least the lower portion of the conduit. When the valve is opened, fluid passes from the lower fluid inlet to the upper fluid outlet and through the venturi conduit to induce fluid flow from the reservoir through the venturi port. When the valve is closed, fluid is prevented from flowing from the lower fluid inlet to the upper fluid outlet, and fluid above the valve is drained into the reservoir through the drain port.

摘要： A yard hydrant of the venturi check valve-fluid reservoir type has a manually operable flow diverter valve which will provide full fluid flow through the hydrant to effectively siphon residual fluid from the reservoir without removal of hoses, backflow preventers or the like from the nozzle of the hydrant. The flow diverter valve is located upstream of the fluid discharge nozzle of the hydrant. A tube connects the venturi check valve with the extreme bottom of the reservoir so that all the residual fluid in the reservoir can be removed therefrom.
