The valve pressure module is adapted to the fire extinguisher compression spring of the valve head of the finished fire extinguisher, and the electric start module is used to trigger the baffle module to make the valve pressure module press down the fire extinguisher compression spring.

The micro-power consumption electric start instantaneous multi-purpose fire extinguisher valve actuator comprises: a pressure valve module 1, a baffle module 2, and an electric start module 3. The pressure valve module 1 and the electric start module 3 are both installed on the baffle module 2, and the baffle module 2 is installed on the finished fire extinguisher valve head 4. The pressure valve module 1 is adapted to the fire extinguisher compression spring 41 of the finished fire extinguisher valve head 4, and the electric start module 3 is used to trigger the baffle module 2 to make the pressure valve module 1 press down the fire extinguisher compression spring 41.

[0021] The pressure valve module 1 includes a pressure block spring tube 11, a pressure block spring 12, a concave cylindrical pressure block 13 and a pressure block spring tube plug 14; the pressure block spring 12 is located in the vertical pressure block spring tube 11, the pressure block spring tube 11 is sealed in the pressure block spring tube 11 by the spring tube plug 14, and the lower end of the pressure block spring 12 is connected to the concave cylindrical pressure block 13.

[0022] The baffle module 2 includes a baffle bin body 21, a baffle bin upper cover 22, a baffle bin lower bracket 23, a baffle spring tube 24, a baffle spring 25, an S-shaped sliding baffle 26 and a baffle spring tube plug 27; the S-shaped sliding baffle 26 is located in the baffle bin body 21, and one end of the S-shaped sliding baffle 26 is in contact with the baffle spring 25; the baffle spring 25 is located in the baffle spring tube 24, the baffle spring tube 24 is fixedly installed on the baffle bin body 21, and the other end of the baffle spring tube 24 is connected to the baffle spring tube plug 27.

[0023] The electric starting module 3 includes a wiring terminal 31 , a wire 32 and a thermoplastic fast-ignition composite support block 33 . The thermoplastic fast-ignition composite support block 33 has an electric ignition head therein, and the electric ignition head is connected to the wiring terminal 31 via the wire 32 .

[0025] The working principle of the micro-power consumption electric start instantaneous multi-purpose fire extinguisher valve actuator provided by the utility model is as follows:

[0026] When a fire occurs, the detection device detects abnormal infrared, smoke or flame information parameters, and outputs a microcurrent to the actuator as soon as it determines that a fire has occurred. After the electric ignition head is energized, the thermoplastic fast-burning composite support block 33 is ignited. The thermoplastic fast-burning composite support block 33 burns and liquefies rapidly due to heat, and loses its support force on the S-shaped sliding baffle 26; the S-shaped sliding baffle 26 moves in the opposite direction under the elastic force of the baffle spring 25. At the same time, as the S-shaped sliding baffle 26 slides, the concave cylindrical pressure block 13, which was originally blocked by the S-shaped sliding baffle 26 above the fire extinguisher compression spring 41, is aligned with the reserved hole of the S-shaped sliding baffle 26. At this time, the concave cylindrical pressure block 13 loses its obstruction and is pushed down by the pressure block spring 12 above it to press the fire extinguisher compression spring 41 on the finished fire extinguisher valve head 4, thereby opening the fire extinguisher valve and releasing the fire extinguishing agent to extinguish the fire.
