Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler head technology for building fire protection, specifically a fire sprinkler head for building fire protection. Background Technology

[0002] Fire sprinklers are a component of fire sprinkler systems. They rely on the ambient temperature to spray water, serving to monitor fire conditions and extinguish fires.

[0003] Fire sprinklers rely primarily on a thermal element to detect ambient temperature. This element consists of a glass tube and a liquid that expands when heated. The liquid absorbs heat and expands, putting pressure on the glass tube. Once the set temperature is reached, the glass tube will break due to excessive pressure, thus enabling the sprinkler head to detect fire and trigger the water spray.

[0004] A fire sprinkler head disclosed in Chinese Utility Model Patent Application Publication No. CN 222150784 U, although the channel is blocked by impurities, requires regular inspection. When a crack or slight leak is found in the heat-sensitive element, it needs to be replaced. Since the heat-sensitive element needs to control the water output of the fire sprinkler head at all times, it is necessary to restrict the water output of the fire sprinkler head with tools before maintenance and replacement. Therefore, the maintenance and replacement steps of the heat-sensitive element are increased, and the replacement efficiency is low. There are problems with the maintenance and replacement of the heat-sensitive element and the restriction of the water output of the fire sprinkler head with tools. In addition, when the sprinkler head is heated, the working fluid inside the glass will act, causing the glass body to crack and the supporting effect of the plug to disappear. The plug will fall off and open, but after the plug falls off, it is easy to cause damage to people or other objects below. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1 to 6 This utility model provides a technical solution: a fire sprinkler for building fire protection, including a main body 1, a bolt 3 threadedly connected to the inner wall of the main body 1, a lifting seat 4 movably connected to the top of the bolt 3, protruding blocks on both sides of the bottom of the lifting seat 4, the blocks being square in shape, a circular groove opened on the top of the lifting seat 4, the diameter of the circular groove being the same as the diameter of the thermal element 5, the thermal element 5 movably connected to the top of the lifting seat 4, and a splash plate 2 fixedly connected to the bottom of the main body 1;

[0030] A fixed rod 11 is fixedly connected to the inner side of the main body 1. A movable groove 10 is opened on the top of the movable seat 6. The movable groove 10 is rectangular in shape and its width is greater than the diameter of the middle part of the top block 12. A threaded groove 13 is opened on the outer side of the fixed rod 11. The top block 12 is threadedly connected to the outer side of the threaded groove 13. The movable seat 6 is movably connected to the top of the top block 12.

[0031] A movable seat 6 is movably connected to the top of the thermal element 5. A fixed frame 8 is hinged to one end of the movable seat 6. A main body 1 is fixedly connected to the top of the fixed frame 8. A sealing gasket 7 is movably connected to the inner side of the main body 1. The movable seat 6 is fixedly connected to the bottom of the sealing gasket 7. The movable seat 6 is set by the movable groove 10, the fixed rod 11, the top block 12, the threaded groove 13, the bolt 3, the lifting seat 4, and the thermal element 5. A fire sprinkler for building fire protection has the ability to fix the movable seat 6 by rotating the top block 12 and misaligning the top block 12 with the movable groove 10, so that the water flow cannot be sprayed out. This avoids the need to restrict the water flow of the fire sprinkler with tools before maintaining or replacing the thermal element 5.

[0032] In use, rotate the top block 12, which moves upward. The misalignment between the top block 12 and the movable groove 10 holds the movable seat 6 in place. Then rotate the bolt 3, which moves downward. The lifting seat 4 also moves downward, allowing the thermal element 5 to be removed for maintenance and replacement. After maintenance of the thermal element 5, place it into the lifting seat 4. Rotate the bolt 3 again, which moves the lifting seat 4 upward. The thermal element 5 holds the movable seat 6 in place. Finally, rotate the top block 12, which moves downward, aligning it with the movable groove 10. If the thermal element 5 breaks, the movable seat 6 can pass through the top block 12 without affecting the normal use of the nozzle.

[0033] Example 2

[0034] Please see Figures 1 to 6 This utility model provides a technical solution: a fire sprinkler for building fire protection, including a main body 1, a bolt 3 threadedly connected to the inner wall of the main body 1, a lifting seat 4 movably connected to the top of the bolt 3, a heat-sensitive element 5 movably connected to the top of the lifting seat 4, and a splash plate 2 fixedly connected to the bottom of the main body 1.

[0035] A fixing rod 11 is fixedly connected to the inner side of the main body 1. The diameter of the outlet of the main body 1 is smaller than the diameter of the sealing gasket 7. The diameter of the sealing gasket 7 is smaller than the diameter of the middle part of the movable seat 6. The middle part of the movable seat 6 is circular. A threaded groove 13 is opened on the outer side of the fixing rod 11. The height of the threaded groove 13 is smaller than the height of the fixing rod 11. The top diameter of the fixing rod 11 is smaller than the bottom diameter of the fixing rod 11. A top block 12 is threadedly connected to the outer side of the threaded groove 13. The top of the top block 12 is movably connected to the movable seat 6.

[0036] A movable seat 6 is movably connected to the top of the thermal element 5, and a fixed magnet 9 is fixedly connected to one side of the fixed frame 8. The fixed magnet 9 is rectangular in shape. The fixed frame 8 is hinged to one end of the movable seat 6. The main body 1 is fixedly connected to the top of the fixed frame 8. A sealing gasket 7 is movably connected to the inner side of the main body 1. The movable seat 6 is fixedly connected to the bottom of the sealing gasket 7. With the thermal element 5, movable seat 6, sealing gasket 7, fixed frame 8, fixed magnet 9, and movable groove 10, a fire sprinkler for building fire protection has the feature that after the water flow opens the movable seat 6, the movable seat 6 will not fall off, thus avoiding damage to people or other objects below if the plug falls off.

[0037] In use, when a fire occurs, the expanding liquid inside the thermal element 5 expands in volume due to heat, putting pressure on the thermal element 5. The thermal element 5 may break due to excessive pressure. Without the support of the thermal element 5, the movable seat 6 rotates under the impact of the water flow, and the water flow is sprayed out from the outlet of the main body 1 to extinguish the fire. Because the movable seat 6 is made of metal, when the movable seat 6 comes into contact with the fixed magnet 9, the fixed magnet 9 attracts and fixes the movable seat 6, preventing the movable seat 6 from shaking back and forth after being washed away by the water flow, which would affect the water flow. At the same time, the movable seat 6 is connected to the fixed frame 8, so that the movable seat 6 will not fall off after being washed away by the water flow.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
