Detailed implementation manners
[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0031] As Figure 1 - Figure 5As shown in the figure, the fire sprinkler device for a clean room provided in this embodiment includes a color steel plate 1.

An installation seat 16 is fixedly connected to the bottom of the fire sprinkler 3 through a connection block 15. A liquid-filled heat-sensitive glass bulb 19 is arranged between the installation seat 16 and the sealing plug 14. During use, an installation hole 2 is pre-opened on the color steel plate 1 at the top of the clean room to facilitate embedding the fire sprinkler 3 into the installation hole 2. By screwing the extrusion ring 8, the fire sprinkler 3 can be clamped on the color steel plate 1. During the process of screwing the extrusion ring 8, the sealing plate 5 will be extruded, so that the sealing capsule 6 is embedded into the sealing groove 4, thereby sealing the connection between the fire sprinkler 3 and the color steel plate 1, improving the connection tightness between the fire sprinkler 3 and the color steel plate 1, and blocking the penetration between the clean room and the non-clean area. The extrusion ring 8 is limited and fixed by the limiting unit 9 to prevent the extrusion ring 8 from loosening and ensure the firm connection of the fire sprinkler 3. When a fire occurs, the liquid-filled heat-sensitive glass bulb 19 expands and breaks due to heat, and the water inside the fire pipeline flows out through the spray opening 13 for fire extinguishing.
[0032] In this embodiment, as Figure 5 shown, the limiting unit 9 includes a sliding rod 901 slidably inserted into the positioning block 10. A moving piece 902 is fixedly connected to the lower end of the sliding rod 901. A limiting block 904 is fixedly installed on the lower surface of the moving piece 902.

The liquid-filled heat-sensitive glass ball 19 limits and fixes the sealing plug 14 to prevent the sealing plug 14 from detaching from the spray nozzle 13.
[0037] In this embodiment, as Figure 3 and 4 shown, a sprinkler 17 is fixedly installed at the bottom of the mounting seat 16. The sprinkler 17 is made of stainless steel material. During use, the water flow ejected from the spray nozzle 13 impacts the sprinkler 17, causing the water flow to form a shape that sprays out in all directions, thereby achieving the purpose of fire sprinkler. The sprinkler 17 made of stainless steel material is corrosion-resistant and has a longer service life.
[0038] In this embodiment, as Figure 2 shown, a flange 21 is fixedly installed at the top of the fire sprinkler 3, and a plurality of connection holes 22 are formed on the upper surface of the flange 21. During use, the fire sprinkler 3 is connected to the fire water pipe through the flange 21.
