    摘要： A self-operated droop compensated regulator includes a spring casing (12) and a lower casing, sandwiching a diaphragm (20). The lower casing has axially aligned inlet (22) and outlet ports (24). A one piece cam stem 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 (52). The cam surface moves the disk holder at a nonlinear rate with respect to the diaphragm. The orifice tube has an extension (56) for providing a boost action to the diaphragm. A pressure relief mechanism (44) 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.

    摘要： A balanced pressure regulator includes a valve body (119) having a fluid inlet (116) and a fluid outlet (118) connected by a fluid passageway. A valve seat (122) is disposed within the fluid passageway. A self-aligning valve plug (128)is at least partially disposed within the fluid passageway, the self-aligning valve plug (128) interacting with the valve seat (122) to selectively open or close the fluid passageway. A retainer (139) is partially disposed within a bore of the self-aligning valve plug (128) and operatively connects the self-aligning valve plug (128) to a valve stem (127) having a ball portion. More specifically, the retainer (139) includes a recess adapted to receive the ball portion of the valve stem (127), such that the self-aligning valve plug (128) automatically rotates around the ball portion of the valve stem (127) to achieve alignment and sealing engagement between a valve disc of the self-aligning valve plug (128) and the valve seat (122).

    摘要： A fluid regulating device includes a valve body, a control element, a control assembly, and a sense tube. The valve body has an inlet, an outlet, a valve port, and 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. The control assembly is operatively coupled to the control element and includes a diaphragm disposed adjacent a diaphragm chamber. The sense tube has a first end, a second end, and a sense hole. The first end is positioned to communicate with the diaphragm chamber, the second end is disposed adjacent the outlet, and the sense hole being formed in the sense tube between the first end and the second end and being oriented along an axis that is angled relative to an axis of the outlet.

    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 high-, medium- and low-pressure reduction unit with a means for balancing the delivery piston which includes a reduction unit body (2) which forms a balancing chamber (3) which is connected to a delivery duct (10) and to an intake duct (11) which forms a passage port (12) on which an adjustment piston (13) pushed by an elastic means (17) acts. The particularity of the invention is that it includes a means (30) for balancing the adjustment piston (13), the balancing means (30) being controlled by the pressure that can be detected in the balancing chamber (3) independently of its value.
