[0029] The flow regulating assembly 400 includes an adjusting rod 401 and a blade 402 arranged on the adjusting rod 401. A water baffle 800 is arranged inside the main tube 100. A water permeable port 801 is opened on the water baffle 800. The adjusting rod 401 is rotatably connected to the water baffle 800. By rotating the adjusting rod 401, the degree of blocking of the water permeable port 801 by the blade 402 is adjusted to control the water flow of the water distribution nozzle.

[0030] It should be noted that the main pipe 100 and the water dispersion tray 300 are connected by a connecting claw 200, and there is only one connecting claw 200 to avoid too many connecting claws 200 blocking the water flow; by setting a flow regulating component 400, the water flow of the water distribution nozzle is controlled, thereby improving the use effect of the water distribution nozzle and the thermal performance of the cooling tower.

[0031] In the cooling tower water distribution nozzle of this embodiment, please refer to Figures 1 to 4 There are a plurality of blades 402 , and the blades 402 are arranged around the circumference of the adjusting rod 401 . The water permeable openings 801 have the same number, shape, and arrangement as the blades 402 .

[0032] It should be noted that several blades 402 are located on the same circumference. When the adjusting rod 401 is rotated, the degree of blocking of the water outlet 801 by the blades 402 can be adjusted, thereby adjusting the water flow of the water distribution nozzle; the water outlet 801 and the blades 402 are set one to one, and the two have the same shape and arrangement.

[0033] In the cooling tower water distribution nozzle of this embodiment, please refer to Figures 1 to 5 The baffle 800 has a cavity formed therein, and the blade 402 is located within the cavity. Furthermore, a through hole 802 is formed in the middle of the baffle 800, and the adjustment rod 401 is rotatably disposed within the through hole 802. The top of the adjustment rod 401 extends outside the through hole 802 and is connected to the first adjustment disk 403.

[0034] It should be noted that a bearing can be provided at the junction of the adjusting rod 401 and the water-blocking plate 800 to enable the adjusting rod 401 to rotate relative to the through hole 802; the first adjusting disk 403 is located outside the through hole 802 and above the through hole 802, which plays a certain protective role for the bearing.

[0038] It should be noted that the rotating block 406 is connected to the bottom of the adjusting rod 401, and the second adjusting disk 404 is set to a conical structure, which can not only provide a certain degree of protection for the rotating block 406, but also avoid blocking the water flow; by setting the rotating block 406, it is convenient to rotate the adjusting rod 401 to adjust the water flow, improve the water distribution effect of the cooling tower, and thereby improve the thermal performance of the cooling tower.

[0039] In the cooling tower water distribution nozzle of this embodiment, please refer to Figures 1 to 4 A limit block 405 is further provided on the adjusting rod 401 , and the limit block 405 and the first adjusting disk 403 are located on different sides of the through hole 802 .

[0040] It should be noted that, by providing the limiting block 405 and the first adjusting disk 403 , the axial position of the adjusting rod 401 is limited, thereby improving stability.

[0041] In the cooling tower water distribution nozzle of this embodiment, please refer to Figures 1 to 5 A reverse lock buckle 500 is provided on the outer wall of the main tube 100, and the reverse lock buckle 500 includes a guide inclined portion 501 and a vertical portion 502 from bottom to top.

[0045] During use, the main pipe 100 is inserted into the mounting hole on the cooling tower, and the water flow of the water distribution nozzle is controlled by the flow regulating component 400. After being accelerated by gravity, the water flows through the water permeable port 801 and the water outlet to the water dispersion plate 300. Part of the water flows impacts the water dispersion plate 300 and is evenly dispersed around. Part of the water flows through the gap between adjacent arc-shaped discs 301 and falls. A small part of the water flows along the arc-shaped water dividing strip 303 to disperse around, thereby achieving uniform water distribution.
