HIGH PRESSURE TANK VALVE SEALING BY USING THE ELASTIC PROPERTIES OF O-RINGS |
摘要 |
A valve for a pressure vessel system includes a housing having a cavity defined by an inner surface of the housing. The housing further includes a rod aperture and a pair of fluid flow ports. An actuator is disposed adjacent the housing. The valve also includes a piston having a rod coupled to a piston head. The piston head is disposed in the cavity of the housing, and the rod disposed through the rod aperture. The rod is also coupled to the actuator. A ring seal is disposed between the piston head and an inner surface of the housing. The ring seal biases the piston head toward one of the fluid flow ports and seals the one of the fluid flow ports to close the valve when the actuator is deactivated. The ring seal is elastically deformed and the fluid flow ports are opened when the actuator is activated. |
