In order to prevent the car chassis from rusting, a fan-shaped spray nozzle is required to spray the car chassis.

[0003] However, in actual use of the existing fan-shaped spray nozzles, due to the change in flow rate causing pressure changes or the pressure fluctuations of the pressure source itself, the particle size distribution range of the sprayed material will be larger and more uncertain, affecting the use effect of the fan-shaped spray nozzles.

[0020] In one embodiment, as Figures 1-3As shown in the figure, a sector sprinkler head includes: a sprinkler head body 1, on which a nozzle 2 is provided. It also includes a diameter adjustment component used to adjust the diameter of the nozzle orifice of the nozzle 2. The diameter adjustment component is arranged inside the nozzle 2 and includes a fixed rod 3 disposed on the inner wall of the nozzle 2. On the outer side wall of the fixed rod 3, two groups of rotating plates 4 are rotatably arranged. One end of each of the two groups of rotating plates 4 is provided with a torsion spring 5, and the other ends of the two groups of torsion springs 5 are both arranged on the inner wall of the nozzle 2 and are both sleeved on the outside of the fixed rod 3. The other ends of the two groups of rotating plates 4 are both set as arc surfaces. The sprinkler head body 1 and the nozzle 2 are made of tungsten steel. The gap of the nozzle 2 is 0.2 - 0.4 mm. The sprinkler head body 1 and the nozzle 2 are used for spraying water or PVC glue. During use, it can be connected to a feed pipe through the sprinkler head body 1, and the sprayed material is transported to the inside of the nozzle 2 through the feed pipe. While spraying, the two groups of rotating plates 4 can be squeezed according to the feeding speed of the feed pipe, so as to drive the two groups of rotating plates 4 to rotate. At the same time, with the cooperation of the two groups of torsion springs 5, automatic adjustment of the nozzle 2 diameter to adapt to different pressures is achieved. It can dynamically adjust the distribution range of water droplet diameters under variable working conditions to make it tend to a stable range, without the need to replace nozzles 2 with different diameters according to the flow demand, improving the applicable range of this sector sprinkler head. By setting the diameter adjustment component, the diameter of the nozzle 2 can be adjusted according to the flow demand, realizing automatic adjustment of the nozzle 2 diameter to adapt to different pressures. It can dynamically adjust the distribution range of water droplet diameters under variable working conditions to make it tend to a stable range, without the need to replace nozzles 2 with different diameters according to the flow demand, improving the applicable range of this sector sprinkler head, which is quite practical.

[0021] As Figures 1-4 shown, a filter screen 6 is arranged inside the sprinkler head body 1. The filter screen 6 is hermetically arranged on the lower end surface of the nozzle 2 and is detachably arranged. When spraying water, the filter screen 6 can be installed to facilitate water filtration. When spraying PVC glue, the filter screen 6 can be removed to facilitate PVC glue spraying. A sealing ring 7 is arranged at the connection between the nozzle 2 and the filter screen 6. By setting the sealing ring 7, the filtering effect of the filter screen 6 is improved.

[0022] The above embodiments disclose a sector-shaped nozzle. When in use, it can be connected to the feed pipe through the nozzle body 1, and the sprayed material is transported to the inside of the nozzle 2 through the feed pipe. When spraying water, the filter screen 6 can be installed to facilitate water filtration. When spraying PVC glue, the filter screen 6 can be disassembled to facilitate PVC glue spraying. While spraying, the two rotating plates 4 can be squeezed according to the feeding speed of the feed pipe, so as to drive the two rotating plates 4 to rotate. At the same time, with the cooperation of the two torsion springs 5, automatic adjustment of the nozzle 2 diameter to adapt to different pressures is realized, enabling the distribution range of water droplet diameters to be dynamically adjusted under variable working conditions and tending to a stable range, without the need to replace nozzles 2 with different diameters according to flow requirements, thus improving the applicable range of this sector-shaped nozzle.
