摘要： The meter 2, e.g. a gas meter includes an inlet boss 4 providing an unregulated supply of gas via a valve means 8 which regulates the flow of gas as it passes into a chamber 6. The valve means 8 forms part of a governor which is formed integral with the gas meter. The valve means 8 includes a valve stem 12 which has a bore 18 extending throughout the length of the valve stem. The valve stem passes through the chamber 6 and through a first diaphragm 22 to which it is sealably connected and is terminated on the surface of second diaphragm 34. The first diaphragm 22 separates second and third chambers 24, 28, the second chamber 24 being in communication with the first chamber 6. The third chamber 28 is connected via the bore 18 in the valve stem 12 to the unregulated gas supply. The second diaphragm 34 separates fourth and fifth chambers 32,38, the chamber 38 is vented to the atmosphere. In normal operation the chamber 32 is connected by a control valve 46 to the chamber 6, and the various balance of forces through the governor allow the gas supply to be regulated. The control valve 46 when operated by a solenoid 48 into a second position causes the chamber 32 to be connected to the chamber 28 and the inlet pressure is communicated via the conduit 54, 50 to the chamber 32 causing the governor to shut off the gas supply.

摘要： A regulator (21) is shown for controlling pressure as well as for selectively fully enabling or stopping flow. A valve housing (23) includes inlet (25) and an outlet (27) and a seat (33) in between, the flow past which is controlled by valve (71). A control housing (41) is attached to the valve housing (23). An elongated rod (75) connects the valve (71) and a piston or diaphragm (197). Spring (81) is provided for valve bias. An auxiliary piston or diaphragm (207) is positioned in the control chamber (49) on the side of the first piston (197) opposite the valve (71), and is spaced from the first piston (197) by an extender (209) to maintain spacing. First and second ports (67, 69) are connected to the control housing at one end and to the inlet (61) and outlet (63) at the other end by means of conduits (111, 117). One of the conduits (111, 117) includes a valve (113) to control flow in the conduit.

摘要： Diaphragm assemblies for use with fluid control devices are described. An example diaphragm assembly includes a body (202) defining a plurality of chambers (208) to be fluidly coupled to an outlet pressure of a fluid control device. Each of the chambers is spaced along a stem (262) at least partially disposed in the chambers, and the stem is to move to control a flow of fluid through the fluid control device (200). Additionally, the example diaphragm assembly includes a first plurality of diaphragms (258), each of which is disposed in a corresponding one of the chambers, and each of which is coupled to the stem to move the stem in response to the outlet pressure of the fluid control device.
