Automatic safeguard bottle system and automatic control method therefor

An automatic safeguard bottle system that is used for safety protection of multiple protected spaces, comprising:

• at least one safeguard bottle, including a bottle with a pressurized storage medium and a bottle valve, wherein said bottle valve includes a valve body installed on said bottle, a piston movably arranged in an inner cavity of said valve body, and a valve port arranged on a side wall of said valve body, wherein said inner cavity of said valve body is divided into an upper cavity and a lower cavity by said piston, and said lower cavity is connected with an inner cavity of said bottle, and wherein said valve port can open and close according to an upward movement and a downward movement of said piston, respectively, led by a pressure difference between said upper cavity and said lower cavity, for controlling a release and a stop release of said pressurized storage medium;
• multiple nozzles, which are respectively arranged in the corresponding protected spaces and connected with said valve port of said bottle valve through a releasing pipe composed of multiple releasing branches;
• multiple signal acquisition elements, which are respectively arranged in the corresponding protected spaces for collecting signals from said protected spaces;
• an electric control device, which is connected with said upper cavity of said bottle valve for controlling said bottle valve;
• multiple electric zone valves, which are respectively arranged on the corresponding releasing branches for controlling said releasing branches;
• and
• a controller, which is connected with said signal acquisition elements, said electric control device and said electric zone valves respectively, for controlling said electric control device and said electric zone valves according to a detection signal from said signal acquisition elements,
• wherein, when said detection signal is indicated as an abnormal signal, said controller controls said electric control device to open said bottle valve such that a pressure in said upper cavity reduces, causing the upward movement of said piston and opening of said valve port, and controls opening of said electric zone valves on the corresponding releasing branches, thereby said nozzles release the medium to said protected spaces within an opening time corresponding to a volume of said protected spaces, and when said opening time expires, said controller controls said electric control device to close said bottle valve such that pressure reduction in said upper cavity stops to cause the downward movement and reset of said piston and closing of said valve port, thereby said nozzles stop releasing said medium;
• and the release and the stop release of said medium controlled through said piston moving upward and downward in said bottle valve are repeatable in cycles before said abnormal signal is no longer present.
