Abstract: The disclosed pressurized vessel has a door seal which is pressurized by a steam supply. A diaphragm actuated solenoid valve is connected between the steam supply and the door seal. The diaphragm solenoid valve precludes the door seal from depressurizing unless the pressure within the vessel is within a preselected pressure tolerance. Also, a check valve is provided to preclude the door seal from completely depressurizing if the pressure at the steam supply is interrupted.

Abstract translation: 所公开的加压容器具有由蒸汽供应器加压的门密封件。 隔膜致动电磁阀连接在蒸汽供应和门密封之间。 隔膜电磁阀阻止门密封件减压，除非容器内的压力在预选的压力公差范围内。 此外，如果蒸汽供应的压力被中断，则提供止回阀以防止门密封完全减压。
