The pipeline is under high pressure for a long time, and it is easy to leak at the pipeline connection and valve installation position
[0004] The application number is: CN201910321079.0, and the publication number is: CN110013638A. The invention patent discloses a fire protection system based on perfluorohexanone fire-fighting agent, which involves the field of fire protection manufacturing technology, including: perfluorohexanone storage tank, the outlet through the first The pipeline is connected to the first inlet of the mixer through the first regulating valve, one end of the second pipeline is connected to the first pipeline through a tee, and the other end of the second pipeline is connected to the inlet of the first outer ring of the nozzle through the second regulating valve ; The dry powder fire extinguishing agent storage tank, the outlet is connected to the second inlet of the mixer through the third regulating valve through the third pipeline; the water mist storage tank, the outlet is connected to the second outer ring of the nozzle through the fourth regulating valve through the fourth pipeline The inlet is connected; the mixer, the outlet is connected with the middle inlet of the nozzle through the fifth pipe; and the nozzle is used for spraying powdered fire extinguishing agent from the middle and / or spraying perfluorohexanone fine water mist fire extinguishing agent from the outer ring; but the fire When the system is in use, it is necessary to use a high-pressure air source. Under the action of the air pressure of the pressure air source, the perfluorohexanone in the perfluorohexanone storage tank and the fine water mist in the water mist storage tank respectively flow at a preset flow rate. It is connected to the second container surrounded by the casing in the nozzle and the trumpet-shaped partition; when the high-pressure gas source is stored, it is easy to leak at the connection. In normal use, it is easy to cause fire extinguishing failure

Embodiment 1

[0030] This embodiment discloses a perfluorohexanone rapid fire extinguishing device, including a perfluorohexanone injection assembly 1, a CO 2 Generating device 2, water mist generating device 3, mixing chamber 4 and nozzle 5, perfluorohexanone injection assembly 1 is connected with nozzle 5 through pipeline 6, CO 2 Both the generator 2 and the water mist generator 3 are connected to the mixing chamber 4, and after being connected to the mixing chamber 4, they are connected to the nozzle 5 through a pipeline 6. The nozzle 5 includes an inner nozzle 7 and a casing 8, and the casing 8 is covered inside On the nozzle 7, a mixing flow channel 9 is formed between the outer shell 8 and the inner spray head 7, and some water mist nozzles 30 are arranged on the outer shell 8; the pipeline 6 connected to the mixing chamber 4 communicates with the mixing flow channel 9, and perfluorohexanone The injection assembly 1 communicates with the inner spray head 7;

Embodiment 2

[0053] This embodiment is further optimized on the basis of Embodiment 1. In this embodiment, the bottom wall 20 of the fire extinguishing agent storage inner cylinder 16 is provided with a depression 28, and the depression 28 extends into the fire extinguishing agent storage inner cylinder 16. A spring 29 is sleeved on the hydraulic cylinder 22 . One end of the spring 29 is connected to the movable end of the hydraulic cylinder 22 , and the other end is connected to the base plate 17 . The movable end of the hydraulic cylinder 22 passes through the base plate 17 and extends into the depression 28 .

[0054] This setting can ensure that there is a buffer at the beginning of pushing the bottom plate 17 to move, and can prevent the perfluorohexanone fire extinguishing agent of the fire extinguishing agent storage inner cylinder 16 from suddenly flowing into the pipeline 6 to cause huge pressure on the pipeline 6, and prevent the pipeline 6 from being suddenly stressed. rupture. ...

Embodiment 3

[0057] This embodiment is basically the same as Embodiment 1 or 2, except that the perfluorohexanone injection assembly 1 includes a fire extinguishing agent storage cylinder and an air bag, the air bag is arranged in the fire extinguishing agent storage cylinder, and the fire extinguishing agent storage cylinder passes through the first A valve 10 is connected with the inner nozzle 7; the air bag is connected with the air pump through the air pipe, and the air pump is connected with the controller.

[0058] In this way, in actual use, the air pump is used to feed gas into the air bag, and then the perfluorohexanone fire extinguishing agent in the fire extinguishing agent storage cylinder is squeezed out.

[0059] It should be noted that the air pump can be connected to the spray head through a pipeline, so that the actual air and CO 2 The gas is mixed in the nozzle, and after working together, the fire extinguishing agent is sprayed; thereby increasing the spraying distance o...

Abstract

The invention discloses a perfluorohexanone rapid fire extinguishing device, which comprises a perfluorohexanone injection assembly, a CO 2 Generating device, water mist generating device, mixing chamber and nozzle, the perfluorohexanone injection assembly is connected to the nozzle through pipelines, CO 2 Both the generating device and the water mist generating device are connected to the mixing chamber, and after being connected to the mixing chamber, they are connected to the nozzle through a pipeline. A mixed flow channel is formed, and a number of water mist nozzles are arranged on the outer casing; when the present invention is used, it is not necessary to store high-pressure gas sources in advance, and the internal pipes and valve connections of the fire extinguishing device will not be subjected to high pressure at ordinary times, which can effectively avoid leakage. , has the advantage of good fire extinguishing effect. In addition, the invention also discloses a fire extinguishing system.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a perfluorohexanone rapid fire extinguishing device; in addition, the invention also relates to a perfluorohexanone rapid fire extinguishing system.
