[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 The utility model provides a technical solution: a quick-detachable spray valve, including a valve body 1, a connecting outlet 2, a valve inlet 3, a pressure connecting port 4, a pressure indicator 5, a first sealing ring 6, a water diversion joint 7, a water diversion plate 8, an aluminum alloy welding plate 9, a first spring 10, a second sealing ring 11, a mounting sleeve 12, a connecting plate 13, a third sealing ring 14, a movable nozzle 15, a second spring 16, a fourth sealing ring 17 and a connecting sleeve 18.

[0026] The valve inlet 3 is provided at the lower end of the valve body 1. Pressure connection ports 4 are provided on both the left and right ends of the valve body 1. The right end of the pressure connection port 4 is connected to a pressure indicator 5. The middle ring of the pressure indicator 5 is provided with a first sealing ring 6. The upper end of the connection outlet 2 is provided with a water diversion joint 7. A water diversion plate 8 is provided inside the water diversion joint 7. An aluminum alloy welding plate 9 is provided at the upper end of the water diversion joint 7. The lower end of the aluminum alloy welding plate 9 is connected to a first spring 10. A second sealing ring 11 is provided at the lower end of the water diversion joint 7.

[0027] The mounting sleeve 12 is mounted at the left end of the pressure connection port 4. A connecting piece 13 is mounted at the left end of the mounting sleeve 12, and a third sealing ring 14 is connected to the right end of the connecting piece 13. A movable nozzle 15 is provided at the right end of the connecting piece 13, and a second spring 16 is connected to the right end of the movable nozzle 15. The lower end of the valve inlet 3 is connected to a connecting sleeve 18, and a fourth sealing ring 17 is mounted on the upper end of the connecting sleeve 18.

[0028] like Figure 1 、 Figure 2 and Figure 4 As shown, the first sealing ring 6 is snapped in the middle of the pressure indicator 5, and the pressure indicator 5 is connected to the right end of the pressure connection port 4 by snapping, the aluminum alloy welding piece 9 is connected to the upper end of the water diversion joint 7 by threading, and the water diversion joint 7 is connected to the upper end of the connection outlet 2 by snapping. When the space temperature reaches 70°C, the aluminum alloy welding piece 9 will dissolve under high temperature and then bounce outward through the first spring 10. The elastic structure facilitates the rapid separation of the aluminum alloy welding piece 9. After the aluminum alloy welding piece 9 falls off, the fire extinguishing agent will produce a twisted spray through the water diversion piece 8, thereby spraying and extinguishing the fire.
