[0022] See also Figure 1-4 A high-efficiency water-saving fire sprinkler comprises a yoke arm seat 1, a first liquid hole 10 is provided at the middle end of the inner surface of the yoke arm seat 1, a drain pipe 5 is fixedly connected to the middle end of the bottom of the yoke arm seat 1, a kerosene expansion seat 6 is fixedly connected between the upper end of the outer surface of the drain pipe 5 and the bottom of the yoke arm seat 1, an annular piston 9 is arranged at the upper end of the inner cavity of the kerosene expansion seat 6, a connecting rod 14 is fixedly connected to the top of the annular piston 9, a movable disk 13 is fixedly connected to the top of the connecting rod 14, a second liquid hole 12 is provided on the inner surface of the movable disk 13, and a plug 11 is fixedly connected to the middle end of the bottom of the movable disk 13.

[0023] The bottom of the yoke arm seat 1 is fixedly connected with a yoke arm frame 2 , the lower end of the inner side of the yoke arm frame 2 is fixedly connected to the splash plate 3 , and the top of the yoke arm seat 1 is provided with a threaded connector 7 .

[0024] Through the above technical solution, the installation of the fire sprinkler is facilitated by the arrangement of the threaded connector 7.

[0025] Movable holes 15 are formed around the inner surface of the yoke arm seat 1 , and the connecting rod 14 slides inside the movable holes 15 .

[0026] Through the above technical solution, the activity of the connecting rod 14 is guaranteed by the setting of the movable hole 15.

[0027] There are multiple second liquid through holes 12 , and the included angles between two adjacent second liquid through holes 12 are equal.

[0028] Through the above technical solution, the circulation of fire-fighting water is guaranteed by the provision of the second liquid hole 12.

[0029] The plug 11 is matched with the first liquid hole 10 , and the plug 11 is inserted into the inner side of the first liquid hole 10 .

[0030] Through the above technical solution, the flow of fire water can be controlled through the arrangement of the plug 11 and the first liquid hole 10.

[0032] Through the above technical solution, the fire extinguishing effect of the fire extinguishing nozzle 8 is guaranteed.

[0033] When in use, the fire sprinkler is installed in the use position through the threaded connector 7. When a fire occurs, the kerosene in the kerosene expansion seat 6 expands after being heated, and then the annular piston 9 can be driven to move upward in the inner cavity of the kerosene expansion seat 6, and the annular piston 9 drives the movable disk 13 to move upward through the connecting rod 14. At the same time, the plug 11 is withdrawn from the first liquid hole 10, and then the fire water enters the drain pipe 5 through the second liquid hole 12 and the first liquid hole 10, and is sprayed outward from the connecting pipe 4 and the fire sprinkler 8, thereby realizing rapid fire extinguishing. When the controlled temperature of the fire drops, the kerosene in the kerosene expansion seat 6 shrinks under the influence of gravity, and then the plug 11 is inserted into the first liquid hole 10 again, thereby reducing the waste of fire water, avoiding the replacement of sprinkler heads, and saving the use cost.
