摘要： A trim assembly for a regulator can include a cage and a plug assembly. The cage can include a peripheral wall defining an opening and a plurality of cage apertures formed in the peripheral wall. The plug assembly can include a plug and a sealing element and can be configured to be moveably received within the opening so that the sealing element contacts an inner surface of the cage to vary a flow area through the plurality of cage apertures depending on the position of the plug.

摘要： A method of custom manufacturing a flame arrestor includes providing a housing having an interior surface and an exterior surface where the exterior surface of the housing is shaped to fit within a fluid passageway. The method includes forming, using an additive manufacturing technique, a three-dimensional lattice structure by depositing a first material onto the interior surface of the housing in a predetermined pattern. The lattice structure includes a plurality of connected lattice members forming channels extending from a first end to a second end of the three-dimensional lattice structure. An element of a second material is provided adjacent to the three-dimensional lattice structure. The second material is different than the first material and the element is configured to draw heat away from fluid flowing through the plurality of channels.

摘要： Plates and plate assemblies for noise attenuators and other devices and methods of making the same are described herein. An example disc-shaped plate described herein includes a plurality of sector-shaped plates that have openings defining flow paths. Each of the plurality of sector-shaped plates has a first radial edge forming a first mating feature and a second radial edge forming a second mating feature that is complementary to the first mating feature such that, when the plurality of sector-shaped plates are arranged together, the first mating feature of each of the plurality of sector-shaped plates mates with the second mating feature of an adjacent one of the plurality of sector-shaped plates.

摘要： A control assembly can be configured for use with a pressure regulator having a valve body defining a fluid flow path. The control assembly can include a control member, a stem, and a lever, and can be disposed within the pressure regulator to selectively control fluid flow. The control assembly can include a primary control member and a secondary control member, or a mechanical stop that can operate to restrict flow along the fluid flow path, including when the stem disconnects from the lever.

摘要： Monitoring systems and methods for a relief valve system. In one example, a monitoring system for a relief valve includes at least one tilt sensor coupled to one or more of a cover or a latch of the relief valve. The at least one tilt sensor is associated with an interface. Upon detection by the at least one tilt sensor that one of the cover is open or the latch is unlocked, a signal is transmitted by the interface indicating one or more of the cover is open or the latch is unlocked.

摘要： A valve seat assembly for use in a fluid control valve. The valve seat assembly includes a pad holder and a support ring. The pad holder includes a support body configured to support a seat pad and a plurality of alignment struts projecting radially outwardly from the support body. The support ring extends around the radially outer perimeter of the alignment struts. The pad holder slides into and out of an operative position in the support ring.

摘要： A fluid regulator includes a balance port regulator valve and an actuator coupled to the regulator valve. The regulator valve has an inlet, an outlet, a valve port disposed between the inlet and the outlet, and a valve disc movable along a longitudinal axis between a closed position in which the valve disc sealingly engages the valve port and an open position in which the valve disc is spaced apart from the valve port. The actuator is responsive to fluid pressure to move an actuator stem along the longitudinal axis. A connector assembly operably and removably connects the valve disc to the actuator stem.

摘要： Thief hatches with diaphragm assisted sealing are disclosed. An example apparatus includes a base attachable to a tank, and a cover attachable to the base via a hinge. The example apparatus further includes a vacuum seal assembly couplable to the cover, and a diaphragm coupled to a stem of the vacuum seal assembly. The diaphragm is moveable in response to a pressure differential between a first pressure within the tank and a second pressure exterior to the tank.

摘要： A stabilizer cartridge for enhancing stability of a fluid regulator is provided. The stabilizer cartridge includes a body, a first disk, and a second disk. The body has a through-bore and an external flange. The first disk has one or more windows and an aperture, and is fixed on an exterior surface of the body. The second disk is slidable along the exterior surface of the body and is biased into contact with the first disk by a biasing element that is positioned between the external flange and the second disk.
