    摘要： An improved trap primer valve may include a valve body having a central tube having a proximal end coupled to an outlet orifice and an open distal end extending into a longitudinal bore of the valve, such that fluid exiting the outlet orifice passes through the central tube. A plug, including a head portion and a rod extending from the head portion into the central tube, may be configured to selectively seat against the distal end of the central tube. An annular cartridge surrounding the central tube may have one or more apertures leading to a partially water-filled inner chamber, and may be configured to unseat the plug in automatic response to a fluctuation in system water pressure, thereby opening the valve and charging a downstream trap.

    摘要： An anti-oscillation valve for and in a trap primer to restrict the flow of water from the supply line to an upper chamber of the trap primer and to facilitate the flow of water from the upper chamber to the supply line. The anti-oscillation valve having a body with a water supply bore provided therethrough. The bore includes portions defining an inlet and an outlet. First and second bore shoulders are formed in the bore. A filter screen is retained in engagement with the first bore shoulder. An anti-oscillation valve disc freely rests on the second bore shoulder and is retained between the first bore shoulder and the second bore shoulder. The anti-oscillation valve disc includes a valve disc orifice defined through and communicating the inlet with the outlet.

    摘要： In accordance with the present invention, a drain trap primer system comprises a water supply line for fluid connection between a pressurized water source and a drain trap. A valve which is operable between an open position and a closed position is in fluid connection within the supply line. An actuation means is provided for switching the valve between the closed position and the open position, and a control mechanism signals the actuator to open and close the valve at selected time intervals.

    摘要： A dialysis service box for centralized control and plumbing arrangement of a dialysis machine is disclosed. The dialysis service box includes a plumbing arrangement having a supply inlet for supplying a fluid to the dialysis machine, a backflow preventer for preventing retrograde flow through the plumbing arrangement, a trap primer for maintaining a trap seal designed to prevent waste gases from flowing into the dialysis service box and a waste connection for allowing waste from the dialysis machine to exit. The dialysis service box can be universally installed to operate, control and adjust any dialysis machine that requires supply connection, waste connection, backflow preventer and trap primer, or any combination of the foregoing.
