  • Valve apparatus for high pressure gas containers
    Patent number: 9371913
    Abstract: A valve apparatus is comprised of a solenoid valve, a manual valve, a pressure relief device, a check valve, an excess flow shut-off device, and a temperature sensor. The temperature sensor is arranged inside the tank in an ambient atmosphere. The sealing member is prevented from falling off from the recess by a floating seal structure. The sealing effectiveness is improved by employing a double seal configuration and also by a smooth surface roughness. A high pressure seal structure is presented. The improved pressure relief device design for 75 MPa application has been presented.
