摘要： A fluid regulating device includes a regulator valve having a valve body defining an inlet and an outlet and a valve port disposed between the inlet and the outlet. A housing assembly is disposed adjacent the valve port, and the housing assembly includes a first aperture adapted to receive a valve disc. A balancing diaphragm is secured to a portion of the valve disc and a portion of the housing assembly, and a portion of a balancing cavity is defined by a top surface of the balancing diaphragm and an interior surface of the housing assembly. A sensing passage extends from the inlet of the regulator valve to the balancing cavity such that the inlet of the regulator valve is in fluid communication with the balancing cavity.

摘要： A self-operated droop compensated regulator includes a spring casing (12) and a lower casing (14), sandwiching a diaphragm (20). The lower casing has axially aligned inlet (22) and outlet ports (24). A one piece cam stem (26) and relief seat (30) is mounted for movement with the diaphragm and includes a first cam surface (33) for directly engaging a movable disk holder (58). The disk holder is movable in a straight line within an orifice tube (50) that supports the valve seat. The cam surface moves the disk holder at a non linear rate with respect to the diaphragm. The orifice tube has a removable boost end cap (80) for providing a boost action to the diaphragm. A pressure relief mechanism is incorporated within the upper portion of the diaphragm. A bias spring (64) acts, between a second similar cam surface (34) on the opposite side of the stem and the disk holder, to maintain the first cam surface in contact with the disk holder. The boost end cap is snapped in position over the end of the orifice tube and has a plurality of fingers (84) with latch portions that engage an annular groove on the orifice tube. One of the fingers (84a) has a hook end that forms a guide for the rear of the cam stem in a sliding contact. A hole (82) in the end cap reduces the boost effect. Parts that move against each other are of different materials for minimum resistance.

摘要： A fluid regulating device includes a valve body having an inlet, an outlet, and a valve port, a control element adapted to be displaced relative to the valve port to control the flow of a fluid between the inlet and the outlet, a control assembly operatively coupled to the control element and including a diaphragm disposed adjacent a diaphragm chamber, and a sense tube. The sense tube has a first end, a second end, and a sense hole formed adjacent the second end. The first end is positioned to communicate with the diaphragm chamber, and the second end is disposed adjacent the outlet, with the second end being movable, relative to the first end, between a first position within the valve body and a second position extending outside of the valve body, the movement being in response to fluid flowing between the inlet and the outlet.

摘要： A pressure control assembly is provided that is coupled to a fluid regulator having a regulator body, an actuator, and an exhaust vent. The actuator includes an actuator housing, a diaphragm disposed within the actuator housing, a first chamber defined adjacent a first side of the diaphragm, and second chamber defined adjacent a second side of the diaphragm. The exhaust vent is formed in the actuator housing to fluidly couple the first chamber to the atmosphere. The pressure control assembly includes a flexible element positioned within an orifice of the exhaust vent. The flexible element is movable within the orifice in response to changes in the pressure in the second chamber.

摘要： A balanced port control assembly includes a control element with a valve plug coupled to a valve stem and a pressure sensing labyrinth defined at least partly by the valve plug. The pressure sensing labyrinth provides for fluid communication between a sealing surface of the valve plug and a balancing diaphragm carried internally of the control element. The pressure sensing labyrinth includes at least one pressure sensing passage extending from the sealing surface and into the valve plug along a central longitudinal axis of the control element. So configured, fluid pressure resident on the sealing surface of the valve plug is also resident on the balancing diaphragm such that equal and opposite forces are applied to the control element.

摘要： A process fluid regulator includes a regulator body having a fluid inlet and a fluid outlet connected by a fluid flow path. A control element is disposed within the fluid flow path, the control element cooperating with a seat to control fluid flow through the regulator body. An actuator is attached to the regulator body, the actuator providing force to move the control element relative to the seat. The actuator includes a housing and a diaphragm within the housing, the diaphragm dividing the actuator housing into an upper chamber and a lower chamber. A high pressure bleed valve is attached to the lower chamber to vent residual gas from the lower chamber, which creates additional volume for process liquid in the lower chamber. This additional volume improves effectiveness and response time of the process fluid regulator.

摘要： A fluid regulating device includes a regulator valve having an inlet, an outlet, and a valve port disposed between the inlet and the outlet. An actuator is coupled to the regulator valve and includes a valve disc that displaces between a closed position and an open position. The device also includes an overpressure protection device adapted to stop flow from the inlet to the outlet when pressure in a control cavity reaches a predetermined level. The overpressure protection device includes a sensing tube having a first end in fluid communication with the control cavity and a second end in fluid communication with the outlet. The sensing tube has a first portion extending parallel to the flow axis. One or more apertures are disposed in the sensing tube adjacent to the second end, and each of the apertures has a centerline that is perpendicular to the flow axis.
