However, in the existing system, there may be a situation where the high-pressure nitrogen storage bottle is activated after the control system is started, but the heptafluoropropane storage bottle is not activated. With the injection of high-pressure nitrogen (15MP), the pressure in the heptafluoropropane storage bottle far exceeds The safety pressure (5.6MP) in the self-stored bottle will burst, causing a safety accident

The invention provides a high-pressure safety switching device for a prepared type heptafluoropropane fire extinguishing system. The high-pressure safety switching device comprises a gas control valve, wherein the gas control valve is internally provided with a movable valve core, a high-pressure nitrogen inlet, a high-pressure nitrogen outlet and a control gas opening, wherein the high-pressure nitrogen inlet is communicated with a high-pressure nitrogen storage container; the high-pressure nitrogen outlet and the control gas opening are respectively communicated with a heptafluoropropane storage container; the movable valve core moves under the effect of gas flow input from the control gas opening, so that the high-pressure nitrogen inlet and the high-pressure nitrogen outlet are communicated; nitrogen output from the high-pressure nitrogen outlet is sent into the heptafluoropropane storage container. The high-pressure safety switching device for the prepared type heptafluoropropane fire extinguishing system is simple and compact in structure, can enable high-pressure nitrogen not to be inflated when the heptafluoropropane storage container is not started up, guarantees the safety of the whole fire extinguishing system, can release high-pressure nitrogen when the pressure is reduced or constant, and can obtain a better fire extinguishing effect finally.
Description
technical field [0001] The invention relates to a switch device for a fire extinguishing system, in particular to a high-voltage safety switch device for a back-up type heptafluoropropane fire extinguishing system. Background technique [0002] In the existing gas fire extinguishing system, the backup pressure heptafluoropropane fire extinguishing system installs heptafluoropropane and high-pressure nitrogen in different storage bottles respectively. When the control system is started, high-pressure nitrogen is first quickly injected into the storage bottle containing heptafluoropropane as a driving force. The gas pushes the heptafluoropropane into the fire network pipe and finally sprays out the fire nozzles to extinguish the fire. However, in the existing system, there may be a situation where the high-pressure nitrogen storage bottle is activated after the control system is started, but the heptafluoropropane storage bottle is not activated. With the injection of high-pre...
