Title:
AUTOMATIC PRESSURE RELIEF VALVE, AND DATA DISASTER BACKUP STORAGE DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/236491
Kind Code:
A1
Abstract:
Disclosed in the present invention are an automatic pressure relief valve, and a data disaster backup storage device comprising same. The automatic pressure relief valve comprises a valve body, a movable member and an elastic member. The valve body is provided with a pressure relief hole. The movable member is configured to be capable of moving between a first position and a second position. When the movable member is at the first position, the pressure relief hole is closed; and when the movable member is at the second position, the pressure relief hole is open. The elastic member is used to provide an elastic force towards the first position to the movable member. When the temperature rises gradually, the air pressure on one side of the pressure relief hole rises continuously with the increase in temperature, and finally, the elastic force of the elastic member is overcome to form a gap between the movable member and the valve body; and cooling liquid may be discharged in a high-temperature and high-pressure steam state, and in addition, the temperature and the air pressure of a hollow cavity are reduced. When the air pressure decreases to a certain value, the elastic member pushes the movable member back to the first position, and the pressure relief hole is reclosed. The process is repeated multiple times until the cooling liquid is completely discharged, and the cooling liquid may absorb heat sufficiently, which is beneficial for improving the heat resistance and durability of the data disaster backup storage device.
