摘要： A gas regulator comprises an actuator and a valve body, wherein the actuator includes a valve disc with a cylindrical shroud that extends beyond the valve disc to direct the flow of fluid through the regulator toward the outlet of the valve and away from the actuator. This configuration advantageously reduces the amount of pressure drop experienced by the actuator during normal operation, thereby minimizing a phenomenon known as “droop.” At least in one embodiment, the shroud can be adjustable and/or removable to allow the regulator to be tuned for specific applications.
摘要翻译：气体调节器包括致动器和阀体，其中致动器包括具有圆柱形护罩的阀盘，其延伸超过阀盘，以将流体流过调节器朝向阀的出口并远离致动器。该配置有利地减少了在正常操作期间致动器所经受的压降量，从而将被称为“下垂”的现象最小化。至少在一个实施例中，护罩可以是可调节的和/或可拆卸的，以允许调节器针对具体应用进行调节。

摘要： A gas regulator includes an actuator, a regulator valve, and a secondary device. Downstream pressure feedback is provided to the actuator and the secondary device via a Pitot tube disposed within an outlet of the regulator valve. The Pitot tube has a first branch having an end connected to the actuator to place the actuator control cavity and diaphragm in fluid communication with downstream pressure within the outlet for maintaining the outlet pressure at an actuator setpoint pressure. The Pitot tube also has a second branch having an end connected to the secondary device to place the interior of the secondary device in fluid communication with downstream pressure within the outlet for responding to changes in the downstream pressure when the outlet pressure diverges from a predetermined normal operating pressure range.

摘要： A gas regulator includes an actuator, a regulator valve, and pressure loading device. The pressure loading device provides a pressure load to a surface of a diaphragm of the actuator to act against a downstream pressure being applied to the opposite surface of the diaphragm and being controlled by the regulator. As the downstream pressure varies and the diaphragm displaces to move a control element to regulate the downstream pressure, the pressure loading device maintains a specified load pressure. The regulator may further include a balanced trim applying a balancing force to offset a force of an upstream pressure on the control element.

摘要： A fluid regulating device comprises an actuator with upper and lower housing components. The upper and lower housing components are secured together at mating flanges via a plurality of fasteners. The upper housing component is formed with a vent to contain a relief valve, which exhausts fluid to the atmosphere under overpressure conditions. The upper housing component is constructed such that it does not require a pedestal or fins extending between the vent and the flange, which advantageously provides a completely unobstructed, continuous, ring-shaped flange for receiving and manipulating the fasteners during assembly and/or maintenance of the regulating device.

摘要： A regulator comprises a regulator valve and an actuator. The regulator valve comprises a valve body equipped with a customized valve port. That is, the valve seat is designed to have a customized seat height depending on a diameter of an orifice through the valve port, a longitudinal dimension of an orifice through the valve port, and/or a flow capacity of the valve port. Such a design advantageously maximizes the efficiency at which gas flows through the regulator. The actuator is coupled to the valve body and comprises a valve disc disposed within the valve body and adapted for displacement between a closed position engaging the valve seat and an open position spaced from the valve seat.

摘要： A fail safe retaining plug assembly for a slam-shut safety device includes a reset pin, a retaining plug attached to the reset pin at a proximal portion, and a safety disk attached to the reset pin at a distal portion. The retaining plug assembly is sufficiently long to prevent the safety disk from falling off of the distal portion before the safety disk contacts a valve seat. The retaining plug assembly is also sufficiently long to prevent the retaining plug from falling off of the reset pin before the safety disk contacts the valve seat.

摘要： Example internal relief valves for use with fluid regulators are described. An example internal relief valve includes a relief valve seat coupled to a first end of the relief valve stem and to engage a first side of a sensing apparatus to prevent fluid flow between the first side of the sensing apparatus and a second side of the sensing apparatus when the internal relief valve is in a closed position. A bleed hole within a surface of the sensing apparatus and separate from the opening of the sensing apparatus is dimensioned to provide a controlled flow rate between the first side and the second side of the sensing apparatus when the internal relief valve is in an open position. A seal is disposed along a body of the relief valve stem upstream from the bleed hole and the valve seat to prevent fluid flow between the first side of the sensing apparatus and the second side of the sensing apparatus via the opening of the sensing apparatus when the relief valve is in the open position.
