[0002] Existing pressure-stored explosion suppression devices all use detonators to start up the blasting discs: when a fire or explosion appears in the protection area of the explosion suppression device, the detector detects the light source and gives an electrical signal to the detonator. The detonator explodes and blasts up the blasting disc at the front end of the pressure-stored explosion suppression device. The air pressure sprays the explosion suppression medium into the explosion path to suppress the continued expansion of the flame or explosion.
[0003] However, the detonator of the existing pressure storage explosion suppression device is located at the bursting piece, which may cause an explosion when activated. Summary of the invention

[0005] The main design idea of the utility model is to utilize the function of the existing AQ-3 type electric ignition tube and the fast-reacting gas-producing agent. When excited, the electric ignition tube generates high pressure in a small space to start the gas-producing agent, and a large amount of gas is generated in a short time to increase the pressure in the starting device of the explosion suppression device, and the starting cap is pushed to cut the bursting disc or increase the gas pressure in the explosion suppression device, and the structure is designed based on the principle of opening the bursting disc.
[0006] The performance of the existing AQ-3 electric ignition tube: keep it at low temperature -40℃, normal temperature +23℃, high temperature +90℃ for 4 hours, and then keep it at 10cm 3 A PT curve test is carried out in a closed container with a direct current of 1.20A, which meets the requirements that the ignition time is less than 2.0ms, the time from the beginning of pressure generation to the pressure rising to the maximum is less than 2.0ms, and the peak pressure is greater than 6.9MPa-11.2MPa.
[0007] The main technical scheme of the utility model: a breaker, including an AQ-3 type electric ignition tube, characterized in that the breaker is composed of an upper shell and a lower shell sealed and connected, the AQ-3 type electric ignition tube is placed in the upper shell, and a gas-producing agent chamber composed of an upper shell and a lower shell inner cavity, a medicine box and a gas channel arranged in the lower shell inner cavity are arranged in sequence below the AQ-3 type electric ignition tube, and an aluminum film seal is provided between the medicine box and the gas channel.
[0008] Preferably, the AQ-3 type electric ignition tube, gas generating agent chamber, medicine box and gas channel are located on the same center line.
[0009] Preferably, the inner diameters of the gas-generating reagent chamber, the medicine box and the gas passage decrease successively.
[0010] Preferably, an aluminum film seal is provided between the medicine box and the gas channel.
[0011] Preferably, the lower end of the medicine box is sealed with a 3M aluminum film, which can effectively prevent the internal gas-generating agent from spilling out of the rupture device, and can also break open from the inside when started to discharge the high-pressure gas out of the rupture device.
[0012] Preferably, the medicine box is welded to the inner cavity of the lower shell.
[0013] Preferably, the upper shell and the lower shell are connected by threaded sealing.
[0014] Further preferably, the upper shell and the lower shell are sealed and fixed by thread glue.
[0015] Preferably, outer surfaces of the upper shell and the lower shell are provided with threads.
[0016] Further preferably, the breaker is fixed to the explosion suppression device by threaded connection.
[0017] The improved explosion-causing device of the utility model adopts the commercially available AQ-3 electric ignition tube as the starting part. The gas-generating agent generates gas and increases pressure in a short time, generates high pressure in a narrow cavity, breaks through the 3M aluminum film, and starts the explosion suppression device.
[0018] A medicine box with a 3M aluminum film on the end face is welded inside the shell 2. The 3M aluminum film can effectively prevent the internal gas-generating agent from spilling out of the rupture device and can also cause the rupture device to break open from the inside, discharge the high-pressure gas and start the explosion suppression device.
[0019] Advantages of the utility model breaker:
[0020] 1. The rupture device is located on the outside of the pressure storage tank of the pressure storage explosion suppression device, which is convenient for maintenance and repair;
[0021] 2. The breaker itself does not bear pressure and is connected to the tank body by threads, making it easy to disassemble;
[0022] 3. Compared with using detonators to explode the blasting disc, the rupture device pressurizes the pressure storage tank and uses the high-pressure gas to push the starting cap to open the blasting disc, which greatly reduces the risk of explosion during startup.
