In the existing gas fire extinguishing system, a container valve of a conventional matched driving gas bottle group adopts a diaphragm type structure. The container valve with the diaphragm type sealing structure has the characteristic of reliable sealing performance and is widely used. However, the diaphragm type sealing structure not only requires the diaphragm to have certain strength (ensuring that the driving gas is not exploded under the condition of normal storage), but also can be easily punctured by external force; meanwhile, the pretightening force of the diaphragm during installation is strictly controlled, and in addition, when the system is recovered after action, a new diaphragm needs to be replaced, so that the operation is complex and the repeated use is not facilitated.
