摘要： Control valves and cages that are adapted to reduce flashing and cavitation. A cage for use with a control valve having an inlet, an outlet, and defining a flow passage between the inlet and the outlet. The cage includes a generally cylindrical body and having a central bore, an upper portion, and a lower portion and an inner wall, an outer wall, and an intermediate wall disposed between the inner wall and the outer wall. The inner wall includes an inlet opening and the outer wall including an outlet opening. The inner wall, the outer wall, and the intermediate wall cooperate to define a portion of the flow passage that extends from the inlet opening, through the cage along the inner wall, along the intermediate wall, past a terminal portion of the intermediate wall, along the outer wall, to the outlet opening.

摘要： A pulsation dampener includes a quantity of liquid reactive fluid (e.g., about 20 gallons) contained within a flexible diaphragm and separated from fluid from an external pumped fluid flow. The quantity of liquid reactive fluid is selected to dampen pressure pulses within the external pumped fluid flow. The pulsation dampener is configured to accommodate thermal expansion of the quantity of liquid reactive fluid by one or more of including a quantity of compressible foam within the flexible diaphragm, allowing for a space between the flexible diaphragm when holding the quantity of the liquid reactive fluid and a body of the pulsation dampener, or providing a reset pressure relief valve.

摘要： A damping device, in particular for damping or avoiding pressure surges, such as pulses, in hydraulic supply circuits, preferably in the form of a silencer, has a damping housing surrounding a damping chamber and having a fluid inlet (3) and a fluid outlet (5). A fluid receiving chamber (7) extends between the fluid inlet and the fluid outlet. A fluid flow crosses the damping chamber in a throughflow direction (11) from the fluid inlet (3) to the fluid outlet (5). Parts of the fluid receiving chamber (7) extend transversely with respect to the throughflow direction (11). The fluid receiving chamber (7) immediately adjoins the fluid inlet (3) and the fluid outlet (5). A guide element (51) is provided in the damping chamber. The fluid flow flows against the guide element changing the flow speed of the flow at least in sections.

摘要： A method is provided for actively compensating for pressure changes of a working fluid within a conduit. A first cavity is provided in fluid communication with the conduit. A second cavity is in fluid communication with a control fluid. A plunger is in communication with both the first cavity and the second cavity and is movable in response to pressure changes of the working fluid in the conduit. The plunger is re-centered. Re-centering the plunger includes the following steps. Position data representative of movement of the plunger is collected. The position data is analyzed with a control unit to determine an average position of the plunger which is offset relative to a center position. The average position of the plunger is compared, with a control unit, to the center position. A signal is relayed from the control unit to a control valve to urge the plunger toward the center position.

摘要： The present invention relates to a method of controlling pressure maintenance equipment for a cooling and heating system. More particularly, the present invention relates to a method of operating and controlling, under optimum conditions, pressure maintenance equipment with multiple sensors so as to check for irregularities in the sensors which measure the same physical parameter. In the present invention, measurement values of two or more sensors are used to detect whether an abnormality has occurred in any sensor. If a sensor is determined to be abnormal, a measurement value of the abnormal sensor is excluded when determining a reference control value. Thereby, the pressure can be precisely and reliably controlled in response to actual conditions of the system.
