    摘要： A fire hydrant system relating to protection of a water supply from contamination. The fire hydrant system includes a barrel adapted to communicate at least indirectly with a water supply; a nozzle extending from the barrel; a hydrant valve adapted to controllably regulate communication between the barrel and the water supply; a valve actuator adapted to allow actuation of the hydrant valve; a nozzle cap adapted to at least close off the nozzle opening; and a hydrant shoe in communication with the water supply, the hydrant shoe comprising a backflow prevention assembly, wherein water can flow from the water supply through the hydrant shoe into the barrel at an open position of the backflow prevention assembly disc, and wherein media cannot enter the water supply via the barrel when the backflow prevention assembly disc is in a closed position.

    摘要： The present invention is a plug system having a plug for insertion into a pipeline, wherein the plug system is insertable via a fitting attached to the pipeline. A pre-drilled aperture of the pipeline positioned normal to the cylindrically-shaped pipeline may interfere with a pig traveling through the pipeline. In one embodiment, the plug includes two coaxial cylindrical portions. A first cylindrical portion has a diameter greater than the aperture diameter, while the second cylindrical portion has a diameter less than the aperture diameter. Additionally the plug defines a hole that is oriented perpendicular to an axis of the cylindrical portions, wherein the diameter of the hole is approximately the size of inside diameter of the pipe. The plug has a retaining member to stabilize the plug system. When the plug is installed in the pipe it permit a pig to flow freely, thereby eliminating pigging hazards.

    摘要： A check valve or backflow preventer has a valve mechanism mounted to a valve cover for removal and replacement as a unit. The valve clapper is resiliently supported to accommodate variations in tolerance. The valve seat is removably secured within the valve body by compression of a resilient seal ring to engage opposed walls of the seat and body. A spring pretensioning member facilitates safe replacement and removal of the valve mechanism.
