    摘要: A valve (10) for sealing and selectively opening a flow path from a water-filled inlet (210) to a dry outlet (220) includes a valve body (100) having a valve opening (230) surrounded by first and second annular valve seat regions (110, 120). A drainage channel (510, 512)) connects to a space between the first and second annular valve seat regions (110, 120). A plug (300) is displaceable between an open state and a closed state for closing the valve opening (230). The plug has a first annular seal (310) for sealing against first annular valve seat region (110) and a second annular seal (350) for sealing against the second annular valve seat region (120). The second annular seal (350) is a flexible seal deployed so that it closes prior to closure of the first annular seal (310). Second annular seal (350) is elastically deformed so as to be pressed into contact with the second annular valve seat (120) when the plug (300) reaches its closed state.

    摘要: An air release vent valve used to vent air from a liquid filled pipeline, the air release vent valve having a float valve deployed in a float valve housing extending from the pipeline and a surge suppressing shutter valve deployed in a vent passageway extending from said float valve housing such that, said surge suppressing shutter valve is downstream from said float valve. The surge suppressing shutter valve includes an elastic shutter element that is pre-shaped to a normally open position and is configured to gradually deform to a closed position as a velocity of air flowing through said vent passageway increase so as to dampen the force of the closure of air release vent valve and prevent a pressure surge within the pipeline. Once a liquid level in the pipeline reaches the float valve, a float is raised so as to fully closes the vent passageway.

    摘要: The pressure differential metering device of the present invention is generally deployed as a flow restrictor placed in the valve inlet so it will create a desired differential pressure to signal a pilot valve, for example, that drives the main valve to limit the flow rate through the valve. The pressure differential metering device of the present invention is deployed across the valve inlet port, with its central axis perpendicular to the direction of fluid flow. The flow restriction element of the present invention may be configured in a variety of sizes to create a desired restrictive cross section to the flow, thereby creating the required differential pressure signals for the valve instrumentation and control. The flow restriction element is configured with upstream and downstream apertures that are the openings to passageways to the corresponding upstream and downstream end-ports. The end-ports provide connection arrangements for the control system of the main valve instrumentation.
