Drawings
Fig. 1 is a schematic sectional view of the overall structure of the present invention.
Illustration of the drawings:
the device comprises an outer cylinder 1, an inner cylinder 2, a nozzle plate 3, a diaphragm 4, a sealing element 5, a feedback box 7, a gas generating agent box 8, an ignition head 801, a starting plate 9 and a wire outlet joint 901.
Detailed Description
Referring to fig. 1, a dry powder fire extinguishing device comprises an outer cylinder 1 and an inner cylinder 2, wherein the inner cylinder 2 is installed on the inner wall of the outer cylinder 1, a nozzle plate 3 is installed at the bottom end of the inner wall of the outer cylinder 1, a diaphragm 4 is tightly attached to the upper surface of the nozzle plate 3, a sealing element 5 is installed at the bottom end of the inner cylinder 2, a gas generating component is installed at the top of the inner cylinder 2, and a starting plate 9 is installed above the inner wall of the outer cylinder 1.
In this embodiment, the gas generation assembly comprises a feedback box 7, a gas generation box 8 and an ignition head 801, the feedback box 7 is arranged in the middle of the gas generation assembly, the gas generation box 8 is embedded in the middle of the feedback box 7 in a sliding mode, the ignition head 801 is arranged above the middle of the gas generation box 8, when the ignition head 801 is started, a gas generation agent can be ignited, the gas generation agent generates a large amount of gas and extrudes dry powder after entering the inner barrel 2 from the gas generation box 8, when the pressure of the dry powder reaches a certain value, the diaphragm 4 explodes, and the compressed gas carries the dry powder to be ejected out from a nozzle together, so that a fire disaster is extinguished.
In this embodiment, the outlet connector 901 is installed in the middle above the starting plate 9, and the control lines of the ignition head 801 and the feedback box 7 penetrate through the outlet connector 901, so that the connection between the control line extending out of the ignition head 801 and an external fire alarm controller is facilitated.
In this embodiment, the bottom of the inner barrel 2 is provided with a throat, which can prevent the dry powder from remaining in the inner barrel 2 after the device is started.
The working principle is as follows: when the fire alarm controller is used, when a fire disaster is detected by the connected fire alarm controller, the ignition head 801 is started through the electric wire, the gas generating agent is ignited by the ignition head 801, a large amount of gas is generated and enters the inner barrel 2 from the gas generating agent box 8, when the pressure reaches a certain value, the diaphragm 4 is exploded, and the compressed gas carries dry powder to be sprayed out from the nozzle together, so that the fire disaster is extinguished.
