摘要： An insertable backflow preventer is presented. The backflow preventer is provided with a cylindrical housing. The housing has a flow transition zone, a proximal orifice/ball seat, a ball with a specific weight that equals or is close to the specific weight of the surrounding fluid, and a distal retaining screen. The housing can have a flange provided on the outside of the housing at one end to facilitate securing the valve in a pipe. The valve is self-cleaning, can be placed in any orientation in a pipe and has low hydraulic head-loss. The valve's unique cost-effective design provides for easy and relative quick installation, eliminates the need to reconfigure existing plumbing, and can be performance tested remotely. Properly installed, it can dramatically improve the security of, for example, potable water sources in a building or other context, and inasmuch as when installed it is not visible, it is tamper proof. The valve can be scaled to any size pipe or tube, and due to its internal flow dynamics is self cleaning. Multiple valves can be installed in series, and balls of varying specific weight can be used in each valve in such a series to allow for contexts where a range of fluids are sent through the same line, or to provide fail-safe operation in the event that contaminants change the specific gravity of the fluid.

摘要： Integrated flow control backflow preventer valve (“IFCBPV”) for new and existing wet- and dry-barrel fire hydrants, with barrel drain assemblies for dry-barrel hydrants, and hydrants equipped with such IFCBPVs, are presented. An exemplary IFCBPV can have a retaining screen comprising equidistant concave radial spokes intersecting at a central ring structure, a freely suspended check ball, and a lower ball seat with a seal. The upper surface of the retaining screen can be affixed to the hydrant's axial shaft, and can thus be used to open and close the hydrant via the ball. Alternatively, the retaining screen can be fixed and the axial shaft provided with a cup on its bottom that mates with the freely suspended ball that is caged between the retaining screen and the ball seat. An exemplary barrel drain assembly can comprise a spring-loaded piston, or alternatively, a check ball design as in the main barrel.

摘要： Wet barrel fire hydrants which feature additional structure for reducing the potential that those with ill intent can foul municipal water supplies by introducing toxins or other materials into fire hydrants. Various embodiments include valves which close off portions of the hydrant or water conduit otherwise available for receipt of toxic or other materials when the fire hydrant nozzle cap is unscrewed and open and/or a pump is connected to the nozzle. Such valves preferably open automatically when water is flowing from the water supply through the nozzle, but close off portions of the barrel when the nozzle is open and water is not flowing through the nozzle.

摘要： A one way check valve to be coupled between a fire hydrant water meter that is connected to a fire hydrant and a fire hose that is connected to a water holding tank such as, for example, a fire engine tanker truck to be filled with water from a municipal water supply. The one way check valve includes a spring- biased blocking head which is movable through the check valve from a first position, at which to close a set of fluid passages through the check valve, to a second position, at which to open the set of fluid passages to the flow of water from the fire hydrant. A shaft extends from the blocking head, and a coil spring is wound around the shaft. When water is flowing into the check valve from the fire hydrant and the fire hydrant water meter, the corresponding water pressure causes the water blocking head to move to the second position during which the spring is compressed and the fluid passages are opened to permit the flow of water to the holding tank. When water stops flowing from the fire hydrant and the water pressure is eliminated, the spring will expand and drive the water blocking head to the first position during which the fluid passages are closed to block the backflow of water from the holding tank to the fire hydrant via the fire hose and the fire hydrant water meter.
