Redundant Valve System |
| 摘要 |
A redundant valve system to provide a regulated fluid flow includes a housing having an inlet at an inlet end which receives a pressurized fluid, and an outlet at an outlet end which provides the regulated fluid flow, a first piston assembly arranged in the housing having a first cavity, the first piston assembly configured to regulate the fluid flow, and a first fluid connection connected to the first cavity and to a point along the housing at the outlet end. The redundant valve system may further include a second piston assembly arranged in the housing downstream of the first piston assembly having a second cavity, the second cavity having a second fluid connection to a vent, an upstream valve to control the first fluid connection and control a position of the first piston assembly, and a downstream valve to control the second fluid connection and control a position of the second piston assembly. |

1. A redundant valve system to provide a regulated fluid flow, comprising:
a housing having an inlet at an inlet end which receives a pressurized fluid, and an outlet at an outlet end which provides the regulated fluid flow; a first piston assembly arranged in the housing having a first cavity, the first piston assembly configured to regulate the fluid flow; a first fluid connection connected to the first cavity and to a point along the housing at the outlet end; a second piston assembly arranged in the housing downstream of the first piston assembly having a second cavity, the second cavity having a second fluid connection to a vent, the second piston assembly configured to regulate the fluid flow when the first piston assembly fails; an upstream valve to control the first fluid connection and control a position of the first piston assembly; and a downstream valve to control the second fluid connection and control a position of the second piston assembly, wherein the upstream valve is configured to close the first fluid connection, and wherein the downstream valve is configured to close the second fluid connection. |
