The emergency driving assembly is arranged on the mounting seat 160 and is in transmission connection with the piercing needle 170, and in operation, an acting force is applied to the emergency driving assembly to drive the piercing needle 170 to move to pierce the sealing diaphragm 150.

[0053] In use, under normal circumstances, when a fire occurs, the controller / control center powers the first driving assembly to drive the piercing needle 170 to pierce the sealing diaphragm 150, so that the gas in the inflation cavity 180 flows out, the gas pressure in the inflation cavity 180 decreases, and under the action of the elastic force of the first spring 130, the valve core 120 moves from the closed position to the open position, so that the air inlet 111 and the air outlet 112 are communicated, so that the fire extinguishing agent is sprayed out of the air outlet 112, and the purpose of extinguishing the fire is achieved.

[0054] When the first driving assembly fails, the staff applies an acting force to the emergency driving assembly to drive the piercing needle 170 to move to achieve the purpose of piercing the sealing diaphragm 150.

[0055] The container valve for heptafluoropropane gas fire extinguishing device provided by the utility model can open the container valve through the emergency driving assembly when the first driving assembly fails.

The electromagnet 230 is arranged at the side of the first permanent magnet 220 away from the valve core 120, and the electromagnet 230 is fixedly connected with the mounting base 160, and the magnetic property of the side of the electromagnet 230 opposite to the first permanent magnet 220 is the same as that of the first permanent magnet 220.

[0058] In operation, the electromagnet 230 is powered, and since the magnetic property of the side of the electromagnet 230 opposite to the first permanent magnet 220 is the same as that of the first permanent magnet 220, a magnetic repulsion force is generated between the electromagnet 230 and the first permanent magnet 220. Under the action of the magnetic repulsion force, the piercing needle 170 is driven to move, thereby piercing the sealing diaphragm 150.

[0059] The push plate 210 in the embodiment has simple structure, reasonable design and convenient operation.

[0060] As Figure 4 shown in the figure, in the embodiment, the emergency driving assembly comprises a push rod 310 and a button 320.

[0062] In operation, the staff member presses the button 320, the button 320 drives the push rod 310 to move, the push rod 310 pushes the push plate 210 to move, thereby pushing the piercing needle 170 to move to pierce the sealing diaphragm 150, which has simple structure and convenient operation.

[0063] As Figure 4 shown in the figure, in the embodiment, the emergency driving assembly further comprises a second spring 330, both ends of the second spring 330 are connected with the button 320 and the mounting base 160, and in the natural state, the second spring 330 exerts a spring force on the button 320, so that the button 320 has a tendency to move away from the valve core 120.

[0064] In operation, after the external force is eliminated, the button 320 and the push rod 310 are restored to the original position under the action of the spring force of the second spring 330.

[0065] As shown in Figure 4 In this embodiment, a locking assembly is further included, which is arranged on the mounting seat 160 and / or the push rod 310, and has a locking state and an unlocking state capable of switching with each other.

[0066] When the locking assembly is in the locking state, the locking assembly locks the push rod 310 so that the push rod 310 cannot move; when the locking assembly is in the unlocking state, the locking assembly releases the locking on the push rod 310 so that the push rod 310 can move.

[0067] In operation, in the natural state, the locking assembly is in the locking state, thereby locking the push rod 310, so as to prevent the sealing membrane 150 from being mistakenly punctured due to external force acting on the button 320.

[0068] When extinguishing the fire, the locking assembly is in the unlocking state, the button 320 is pressed to drive the push rod 310 to move, the push rod 310 pushes the push plate 210 to move, thereby pushing the puncture needle 170 to move to puncture the sealing membrane 150.

[0069] As shown in Figure 4 In this embodiment, the locking assembly includes a locking pin 410, the mounting seat 160 is provided with a first insertion hole 161, and the push rod 310 is correspondingly provided with a second insertion hole 311.

[0070] When locking, the locking pin 410 is inserted into the first insertion hole 161 and the second insertion hole 311, and in the natural state, the locking pin 410 can be kept in the first insertion hole 161 and the second insertion hole 311, and when the external force applied on the locking pin 410 exceeds the preset value, the locking pin 410 can move. When unlocking, an acting force is applied on the locking pin 410 to pull out the locking pin 410 from the second insertion hole 311.

[0071] In this embodiment, the locking assembly has simple structure, reasonable design and convenient operation.

[0073] When in use, the damping ring 420 can increase the resistance when the locking bolt 410 is moved, so as to keep the locking bolt 410 in the first insertion hole 161 and the second insertion hole 311 in the natural state.

[0074] As shown in the drawings, Figure 4 In the embodiment, the side of the push rod 310 facing the push plate 210 is provided with the second permanent magnet 340, and the second permanent magnet 340 and the opposite side of the first permanent magnet 220 are different in magnetic property.

[0075] When in operation, the second permanent magnet 340 and the opposite side of the first permanent magnet 220 are different in magnetic property, so that the magnetic attraction is generated between the second permanent magnet 340 and the first permanent magnet 220, and the push plate 210 and the piercing needle 170 are attracted to the push rod 310 under the action of the magnetic attraction, thereby achieving the purpose of avoiding the piercing needle 170 from moving randomly.
