    摘要： A regulator comprises a regulator valve and an actuator. The actuator is coupled to the regulator valve and comprises a control element for controlling the flow of fluid through the regulator valve. The actuator is additionally equipped with a pressure averaging sense tube to sense the actual pressure at the outlet of the regulator valve. The actual pressure is then supplied to a sensing element such as a diaphragm of the actuator to adjust the position of the control element. The pressure averaging sense tube includes an open sensing end and an elongated slot. The elongated slot advantageously senses and averages the pressure across the length of the sense tube to maximize the accuracy of the pressure signal supplied to the sensing element.

    摘要： A pressure reducing valve for gas is provided in which a valve mechanism having opening in a central part a valve hole that communicates with a low pressure passage and a low pressure chamber and including a valve body that is capable of being seated on a valve seat facing a valve chamber communicating with a high pressure passage is housed within a body such that the valve body is connected to a pressure receiving member operating in response to pressure of the low pressure passage and the low pressure chamber, wherein the body (16) is formed by joining a plurality of body members (18, 19) having different strengths, the entirety of the high pressure passage (30, 64) being formed, among the plurality of body members (18, 19), within the body member (18) that has a high strength, and at least part of the low pressure passage (85, 86, 94, 119) and the low pressure chamber (83, 84, 116) being formed, among the plurality of body members (18, 19), within the body member (19) that has a low strength. This enables the cost to be reduced.

    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： The valving element is positively tied to a pressure-sensing and -responsive diaphragm, via a diaphragm-carried insert. The connection is so arranged as to permit relative angular displacement, between the valving element and the diaphragm, so that cocking of the element, in its axial movement, will not occur. The gas filter is formed of a sintered plastic to avoid corrosion and flaking off of metallic particles. An aspirator hole communicates the diaphragm with the low-pressure chamber outlet, but has an artificially lower pressure, than the outlet pressure, introduced to the diaphragm, through the use of an ejector nozzle. A hole formed in the bonnet establishes atmospheric pressure above the diaphragm, but a porous plug in the hole prevents any ingestion of water, from puddle-splashing, take up from wet roads, and the like.
