Embodiment 1

[0070] like figure 1 and figure 2 Shown is Embodiment 1 of the present invention. This embodiment provides a data disaster recovery storage device. The data disaster recovery storage device includes an inner tank 1 with a hollow cavity 11. The hollow cavity 11 is filled with cooling liquid, and the cooling liquid is surrounded by data memory 2. Specifically in this embodiment, the outer wall of the inner pot 1 is recessed inward to form a groove for accommodating the data storage device 2 , that is, the wall of the groove is integrally connected with the wall of the inner pot 1, specifically by welding, or sheet metal stamping, Alternatively, the above structure can be realized by means of flange mounting, which is not limited in the present invention. With this structure, the data storage device 2 can be installed outside the inner tank 1 without affecting the protection of the data storage device 2 by the cooling liquid.

[0071] The inner pot 1 has an opening 12, and co...

Embodiment 2

[0089] like image 3 Shown is Embodiment 2 of the present invention. The automatic pressure relief valve provided in this embodiment is basically the same as the automatic pressure relief valve in Embodiment 1. The difference is that in this embodiment, the movable member 72 is provided with a direction The pressure relief hole 711 has a protruding plunger 723 , and the plunger 723 cooperates with the pressure relief hole 711 to improve the sealing performance of the pressure relief hole 711 . When the pressure difference causes the plunger 723 to escape from the pressure relief hole 711 , the pressure relief hole 711 is opened, and the high temperature and high pressure steam can be discharged through the pressure relief hole 711 . In this embodiment, the pressure relief hole 711 is completely filled by the plunger 723, thereby ensuring that the pressure relief hole 711 is sealed.

Embodiment 3

[0091] like Figure 4 Shown is Embodiment 3 of the present invention. The automatic pressure relief valve provided in this embodiment is basically the same as the automatic pressure relief valve in Embodiment 2. The difference is that in this embodiment, the length of the plunger 723 is shorter , when the movable member 72 is in the first position, only part of the pressure relief hole 711 is filled by the plunger 723, so the movable member 72 is lifted up a short distance so that the pressure relief hole 711 can discharge high temperature and high pressure steam. In addition, the end of the plunger 723 is provided with a chamfer, so when the movable member 72 moves from the second position to the first position, the plunger 723 can easily enter the pressure relief hole 711 to prevent the plunger 723 from being stuck in the pressure relief hole Outside the hole 711, no sealing can be achieved.

Abstract

The invention discloses an automatic pressure relief valve and a data disaster backup storage device including the same. The automatic pressure relief valve comprises a valve body, a movable part and an elastic part, the valve body is provided with a pressure relief hole, and the movable part is configured to be able to When moving between a first position and a second position, when the movable member is in the first position, the pressure relief hole is closed, when the movable member is in the second position, the pressure relief hole is opened, and the elastic member is used to provide the movable member with an elastic force toward the first position . When the temperature gradually rises, the air pressure on the side of the pressure relief hole will continue to rise with the rise of the temperature, and finally overcome the elastic force of the elastic member, forming a gap between the movable member and the valve body, and the cooling liquid can be discharged in the state of high temperature and high pressure steam. At the same time, the temperature and air pressure of the hollow cavity are reduced; when the air pressure is reduced to a certain value, the elastic piece pushes the movable piece back to the first position, and the pressure relief hole is closed again. This is repeated many times until the cooling liquid leaks out, and the cooling liquid can fully absorb heat, which is beneficial to improve the heat resistance durability of the data disaster recovery storage device.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to an automatic pressure relief valve and a data disaster recovery storage device including the same. Background technique [0002] At present, some devices in vehicles, such as driving recorders, generally use built-in hard disks or SD cards to store vehicle data records. After an accident causes the vehicle to catch fire, crash, or fall into the water, the data storage (such as the built-in hard disk or SD card, etc.) is damaged due to poor protection, so that the driving data cannot be read, and the cause of the accident cannot be determined. Therefore, a data disaster recovery storage device for saving data storage has appeared. The protection of impact and falling water is relatively mature, but fire protection technology is not easy to achieve under the premise of cost and volume constraints. In the data disaster recovery storage device in the prior art, the cooling liq...
