Abstract

The invention relates to a fire extinguishing technology, and discloses a controllable spraying cold aerosol fire extinguishing device. The device is characterized by comprising a sprayer, a control valve, a pressure switch, a closed container, a driving gas cylinder, a powder blowing pipe and a siphon, wherein dried cold aerosol powder is accommodated in the closed container; the driving gas cylinder, the powder blowing pipe and the siphon are arranged in the closed container; an opening of the driving gas cylinder is communicated with an inlet end of the powder blowing pipe through a gas pipeline, and the pressure switch, the control valve and a reducing valve are arranged on the gas pipeline sequentially; the pressure switch is connected with the control valve; and an inlet end of the siphon extends into the bottom of the closed container, and an outlet end of the siphon is communicated with the sprayer through a cold aerosol pipeline. According to the controllable spraying cold aerosol fire extinguishing device, the driving gas cylinder is arranged in a powder storage tank, so that the size of the integral device is greatly reduced, and the controller is used for controlling switching off of an electromagnetic valve according to the preset spraying time during fire extinguishing, so that a fire extinguishing agent can be sprayed for multiple times.

Description

technical field [0001] The invention relates to fire-fighting and fire-extinguishing technology, in particular to a cold aerosol fire-extinguishing device with controllable spraying. Background technique [0002] The common gas storage cylinder type fire extinguishing device is usually set up separately from the gas storage tank and the dry powder storage tank, and the fire extinguishing agent is sprayed once when the common fire extinguishing device is used, and cannot be reused. Restoration and maintenance after fire extinguishing will cause a certain amount of waste , and the large size of common devices directly results in a large installation area and limited installation space, which is not suitable for many occasions. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a cold aerosol fire extinguishing device that can be repeatedly sprayed. [0004] In order to achieve the above object, the present inv...
