    摘要: A temperature-controlled pressure regulator assembly includes a regulator having a regulator body, a valve seat, an inlet, an outlet, and defines a flow passage connecting the inlet and the outlet. A control element controls the device, a portion of the flow passage extends through a heat chamber, and a heater is positioned to heat the chamber thereby conveying heat to a fluid in the flow passage. A controller is electrically coupled to the heater and is coupled to a power source. A thermal cut-off fuse is coupled to a control circuit, with the thermal cut-off fuse arranged to electrically decouple the heater from the control circuit in response to a temperature exceeding a threshold, thereby deactivating the heater. The thermal cut-off fuse is disposed in a circular fuse holder and positioned adjacent the heater and adjacent a longitudinal center of the heat chamber.

    摘要: In some examples, a pressure reducing valve includes a valve body defining a defining a flow path and a restricting element within the flow path. A sensing element is configured to modify a position of the restricting element in the flow path. The sensing element defines a first area in fluid communication with the flow path and a second area fluidly isolated from the flow path. The pressure reducing valve includes control circuitry configured to determine a differential pressure over a section of the flow path, determine a position of the restricting element, and determine a flow rate based on the differential pressure and the position of the restricting element.

    摘要: A PRV is provided, comprising an inlet, an outlet, and a pressure regulating system therebetween to maintain a set pressure at the outlet. The PRV further comprises a selection system configured to select between the two working pressures based on the pressure of the fluid at the inlet of the PRV, and to direct the pressure regulating system to maintain the set pressure at the outlet at the selected working pressure. The selection system comprises a pressure-motion transducer for directing the set pressure when in pressure communication with the inlet, and an auxiliary valve having an auxiliary inlet in pressure communication with the inlet and an auxiliary outlet in pressure communication with the pressure-motion transducer. The auxiliary valve is configured to establish pressure communication between its inlet and outlet when pressure in the inlet traverses a predetermined threshold.

    摘要: A dome pressure regulator for regulating gas pressure, having a housing (1), a fixed valve seat (10), a movable valve body (8), a closing spring (9) acting on the valve body (8), and a diaphragm (4) which is connected to the valve body (8) and which is able to be subjected to a control pressure, settable via a gas pressure spring, in the opening direction and to a secondary pressure in the closing direction. The object of the invention is to detect state parameters of the system and to integrate continuous functionality checking and logging of the collected measurement values into the pressure regulator. In order to achieve said object, the invention proposes at least one travel sensor (15), by way of which the stroke of the valve body (8) is measurable, and a sensor-system evaluation unit (17) integrated into the housing.

    摘要: A pressure regulator includes a valve body that defines an inlet and an outlet for a fluid flow through the valve body, a poppet that is moveable within the valve body between an open position and a closed position to control the fluid flow from the inlet to the outlet, and a pressure regulating mechanism that controls a position of the poppet between the open and closed positions. The pressure regulating mechanism includes a diaphragm and a compression spring, and a force balance between the diaphragm and the compression spring determines the position of the poppet. The pressure regulating mechanism further includes a static pressure tap configured to apply a static pressure to the diaphragm, and a dynamic pressure tap configured to apply a dynamic pressure to the diaphragm. The dynamic pressure tap is located at an annular opening adjacent to the poppet, and an area of the annular opening varies with the position of the poppet to vary the dynamic pressure applied to the diaphragm.

    摘要: A pressure regulator, said pressure regulator comprising a housing containing a channel arranged to communicate a fluid from a fluid inlet to a fluid outlet, said channel comprising a valve seat housing, a valve seat and closure member with said closure member operable with the valve seat and valve seat housing to control flow through the channel; wherein the housing comprises a resilient diaphragm in fluid communication with the fluid and in physical communication with the closure member such that the diaphragm is operable to deform in response to a change in pressure of the fluid and such that deformation of the diaphragm causes the closure member to change position, and; wherein the section of the diaphragm not in fluid communication with the channel, is in fluid communication with the exterior of the regulator via a vent aperture and; wherein the closure member comprises an upstream valve element and downstream valve element, wherein the downstream valve element is a ridge operable with an aperture in the valve seat housing to at least partially control fluid flow, wherein said ridge of the closure member is partially or fully inside said aperture in the valve seat housing when the upstream valve element of the closure member is at or between the fully open position and a predetermined partially open position with the valve seat, to provide a restriction to fluid flow but not to fully obstruct flow.
