Explosion-venting method for aerosol fire suppression apparatus
View Patent ↗An explosion-venting method for an aerosol fire suppression apparatus, comprising the following steps: 1) when the aerosol fire suppression apparatus explodes, an explosion-venting device matching the aerosol fire suppression apparatus generating a limited displacement along a direction that a hot air stream of the aerosol fire suppression apparatus is jetting towards; 2) when an extremity of the explosion-venting device reaches an edge of the aerosol fire suppression apparatus, being limited, the explosion-venting apparatus stops the displacement along the direction that the hot air stream of the aerosol fire suppression apparatus is jetting towards, thus achieving for the aerosol fire suppression apparatus the effects of explosion-venting and reduced recoil force.
1. An explosion-venting method for an aerosol fire suppression apparatus, wherein the method comprises the following steps:
1) when the aerosol fire suppression apparatus deflagrates, an explosion-venting device matching the aerosol fire suppression apparatus generates a limited displacement along a direction that a hot air stream of the aerosol fire suppression apparatus is jetting towards;
2) when an extremity of the explosion-venting device reaches an edge of the aerosol fire suppression apparatus, being limited, the explosion-venting device stops the displacement along the direction that the hot air stream of the aerosol fire suppression apparatus is jetting towards, thus achieving for the aerosol fire suppression apparatus the purpose of explosion-venting,
wherein the explosion-venting device comprises a friction layer, a connecting rod, a guiding unit and a limiting device;
the guiding unit provides a sliding guide function for the connecting rod when the connecting rod is moving;
the connecting rod is fixedly connected with the aerosol fire suppression apparatus through the limiting device; when an extremity of the connecting rod is to be separated from the aerosol fire suppression apparatus, the limiting device limits the connecting rod.
2. The explosion-venting method for the aerosol fire suppression apparatus according to claim 1 , wherein the guiding unit is a guiding ring fixedly connected with the connecting rod or a guiding groove arranged on an outer wall of the aerosol fire suppression apparatus and capable of making the connecting rod slide along the guiding groove.
3. The explosion-venting method for the aerosol fire suppression apparatus according to claim 1 , wherein the limiting device is arranged on one end, which is arranged with a nozzle, of the aerosol fire suppression apparatus.
4. The explosion-venting method for the aerosol fire suppression apparatus according to claim 1 , wherein a displacement of the connecting rod is within 30 mm to 80 mm.
5. The explosion-venting method for the aerosol fire suppression apparatus according to claim 4 , wherein the limiting device comprises a flanging fixedly connected with a nozzle end of the aerosol fire suppression apparatus and a clamping claw for fixing the connecting rod.
6. The explosion-venting method for the aerosol fire suppression apparatus according to claim 5 , wherein a buffering component is further arranged between the flanging and the guiding ring.
7. The explosion-venting method for the aerosol fire suppression apparatus according to claim 1 , wherein the aerosol fire suppression apparatus is a portable fire suppression apparatus or a fixed fire suppression apparatus.
8. The explosion-venting method for the aerosol fire suppression apparatus according to claim 2 , wherein a displacement of the connecting rod is within 30 mm to 80 mm.
9. The explosion-venting method for the aerosol fire suppression apparatus according to claim 3 , wherein a displacement of the connecting rod is within 30 mm to 80 mm.
