Problems solved by technology

In this type of building, the fire pump station is concentrated in one place, while the pipelines and sprinklers are scattered and installed in each room on each floor. In this case, water mist or fine water mist sprinklers cannot be used because they do not have the ability to know which room is on fire and which room is on fire. The nozzles in the room will be sprayed by temperature, while the nozzles in other rooms are still closed and do not spray. The closed self-starting function
If there are valuable and water-afraid items such as documents, files, instruments and meters, and computer stations in each room, sprinklers should not be used for fire fighting in such places, because the amount of water sprayed is large, and the water pollution loss caused by sprinkler fire extinguishing is not even small. inferior to fire
It is not enough to use IG541 or FM200 and other non-water-pollution gases to extinguish the fire. They are not only expensive, but not safe for medium and high pressure civilian use. The main disadvantage is that they can only use open nozzles that spray and stop. The system can only be that one room is on fire and all the rooms are sprayed to put out the fire at the same time, which is obviously not possible
In fact, there is no fire sprinkler suitable for the above-mentioned special needs at present.

Embodiment 1

[0097] Embodiment 1: Schematic diagram of a multi-nozzle closed medium and low pressure fine water mist nozzle with a joint nozzle frame at the bottom of the nozzle seat, see figure 1 . The central hole of the nozzle seat of this embodiment is equipped with a filter 10, and the outlet 3 of the central hole of the nozzle seat is blocked by the top surface of the sealing piston 5 with a sealing ring 4, and the upper part of the sealing piston is located in the center of the outlet ring groove 8.1 of the intermediate cavity, and the sealing The stepped column with a small sealing ring at the lower part of the piston is located at the lower part of the middle cavity 8, and passes through the central hole of the annular groove disc 16, and its bottom is tightly held by the temperature-sensitive glass bubble 6, and the adjusting member 9 at the bottom of the frame supports the temperature-sensitive glass Bubble, the ring-shaped groove disc 16 with external threads on the upper part ...

Embodiment 2

[0098] Example 2: For a schematic diagram of a multi-nozzle closed medium-low pressure fine water mist nozzle with jet swirl compound atomization core, see Figure 1.1 and 1.2 . The nozzle given in this embodiment is similar to the nozzle in Embodiment 1, except that the atomizing cores around the nozzle seat are jet swirl atomizing cores 04 . It consists of atomizing core round hole 046, atomizing core cap 044, central jet channel 042 and tangential swirl hole 041. The large end of the inner tapered hole of the atomizing core cap is equal to the diameter of the atomizing core round hole and closely connected with each other. The small end of the tapered hole in the inner chamber of the atomizing core cap shrinks into the nozzle of the atomizing core 045; the shoulder of the outlet ring groove 8.1 is provided with the entrance of the swirl hole 041, and the other end of the swirling hole is connected to the round hole 046 of the atomizing core and is tangent to it (See Fig...

Embodiment 3

[0099] Embodiment 3: Schematic diagram of a multi-nozzle closed medium-low pressure fine water mist nozzle with adjustable springs at the bottom of the nozzle seat, see figure 2 . The nozzle structure of this embodiment is basically the same as that of Embodiment 1. Parts 1, 4, 6, 10, 11, 0X, and intermediate chambers 8 and 8.1 are also similar to Embodiment 1, and will not be described again. The difference is that the center of the nozzle seat A multi-channel diversion grid bubble homogenizer 15 is arranged in the hole, the lower frame of the nozzle holder is integrated with the nozzle holder, and an annular groove disc screw plug 17 is arranged in the center of the bottom of the middle cavity, and the spring 11 can be adjusted to the sealing disc 5 by turning the screw plug 17. preload pressure. A pressure ring 12 with a sealing ring is arranged in the center hole of the nozzle seat, which is used to seal the outlet of the center hole of the nozzle seat together with the ...

Abstract

The invention relates to a multi-jet enclosed medium-low-pressure atomizing head used in fire-fighting automatically spraying to extingiush fire. The invention comprises injector stand, sealing element, intermediate cavity, atomizer, injector framework and temperature-sensing support and has the following settings: the inner of injector stand equipping center bore and imports and exports, inlet of intermediate cavity connecting with outlet of center bore, sealing element locating in intermediate cavity, sealing element plugging center bore outlet, the bottom of intermediate cavity equipping via hole and its outlet connecting with the inlet of atomizer via channel or cavity, equipping two atomizers at least, equipping water channel in atomizer, water channel connecting with atomizer sprayer, one side of sprayer framework being fixed under sprayer and the other side supporting temperature-sensing support, and temperature-sensing support being located between injector framework and sealing element.

Description

technical field [0001] The invention relates to a fire-fighting fine water mist nozzle capable of automatically opening and spraying fire, in particular to a kind of multi-nozzle closed medium-low pressure fine water mist nozzle. Background technique [0002] The sprinkler is the key component of the terminal of the automatic fire extinguishing equipment. It is installed on the protection site to spray water to extinguish the fire, and determines the working mode and fire extinguishing effect of the fire protection system. There are two types of sprinklers widely used in automatic sprinkler systems: one is a closed sprinkler. The other is an open water mist or fine water mist nozzle. [0003] The sprinkler head is a low-pressure closed nozzle. It is usually blocked at the nozzle. When a fire occurs, the temperature-sensitive heat-sensitive component falls off and opens the nozzle, and the water is released to impact the splash plate and sprinkle water around to extinguish t...
