摘要： Multi-stage fluid regulators are described. An example fluid regulator (200) includes a regulator body (202) having an inlet (204) in fluid communication with a source of pressurized fluid. A first fluid valve (208) is disposed within the regulator body and coupled to the inlet to regulate a pressure of the pressurized fluid at the inlet. A second fluid valve (246) is disposed within the regulator body and coupled to the inlet and, via a passageway (248), to the first fluid valve. The second fluid valve is to cause a fluid pressure in the passageway to be regulated to a predetermined portion of the pressure of the pressurized fluid at the inlet.

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 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 two-stage reduction valve for gaseous fluids consists of a high-pressure assembly with a high-pressure diaphragm (10) actuating a valve member disposed in the throat of a gas cylinder and of a low-pressure assembly with a likewise diaphragm-operated valve member (21) positioned in a gas duct (18) extending from the high-pressure assembly. A closing rod (30) connected with an operating handle (41) is restrictedly displaceably connected with a diaphragm spindle (14) firmly connected with the high-pressure diaphragm (10) and has at its upper end an essentially cylindrical bore (43) to displaceably receive the lower end of the closing rod (30). The upward circular mouth (44) of the bore (43) has a reduced diameter and the closing rod (30) has at its lower end a head (45) with a width larger than said reduced diameter but with such a shape that it may be inserted into the bore (43) through the mouth (44) of the bore with the closing rod (30) inclined in relation to the axis of the diaphragm spindle (14), but when inserted it is prevented from being pulled out from the bore.
