摘要： A back pressure balanced relief valve can include a piston, a pressure balancing device, and a pressure sensor. A pressure chamber can be created between the pressure balancing device and the piston. The pressure sensor can be configured to monitor the pressure in the pressure chamber for indications of a potential failure of the balancing device.

摘要： A flow arrangement for a control valve can include a plurality of flow-control components that are movable relative to each other and that define at least part of a flow path from a pressure source to a dome of a pressure relief valve. The flow-control components can be movable relative to each other in response to system pressure to selectively increase or decrease the flow capacity of the flow path. In some cases, flow capacity can be increased or decreased during initial loading of the dome, at low pressures, or at higher pressures.

摘要： A spring-operated relief valve can include a biasing assembly, a valve inlet, a valve seat, and a disc assembly that is biased toward the valve seat by the biasing assembly. A fluid guide, such as a groove or chamber, can be formed at the interface between the valve seat and the disc assembly. The fluid guide can be configured to direct fluid that flows across the valve seat to provide an upward force on the disc assembly during a relief event.

摘要： An illumination system can be configured for use with a liquid level gauge. A mounting bracket can be configured to secure a LED assembly to a frost-proof extension of the liquid level gauge, with the LED assembly disposed adjacent to a second edge face of the frost-proof extension that is opposite a liquid tube. The LED assembly can be thereby configured to illuminate the liquid tube via the second edge face of the frost-proof extension.

摘要： A spring-operated relief valve can include an adjustable main spring to bias the valve closed and a load cell that is configured to measure a force exerted by the main spring. Measurements from the load cell can be used to determine a set or crack pressure in the spring-operated relief valve, and to monitor operation of the spring-operated relief valve.

摘要： A sensing arrangement for a relief valve having a valve body can include a valve body engagement member and a first sensor. The valve body engagement member can be secured to the valve body proximate to a valve seat of the relief valve. The first sensor can be in communication with the valve seat via the valve body engagement member. The first sensor can be configured to detect a valve event via detection of localized pressure changes at the valve seat.

摘要： A clamp assembly to secure a yoke to a valve body of a knife gate valve is provided. The clamp assembly can include a bolt that is configured to extend through a first bushing, a first spring member, a first side wall of the yoke, the valve body, a second side wall of the yoke, a second spring member, and a second bushing. The clamp assembly can be configured to pin the yoke to the valve body, apply a pressure-containing preload to the valve body via the first and second bushings, and compress the first spring member between the first bushing and the first side wall of the yoke and the second spring member between the second bushing and the second side wall of the yoke.
