The spray angle of the hollow cone nozzle is 52°-180°. The spray angle is divided into standard angle and wide angle. The standard angle refers to the hollow cone nozzle with the spray angle less than 80°, and the wide angle refers to the hollow cone with the spray angle greater than 80°. nozzle.

The standard-angle hollow cone nozzle generally adopts a circular nozzle design, and the spray angle is controlled by the rotation of the liquid caused by the nozzle cavity. The wide-angle hollow cone nozzle is based on the circular nozzle hole and increases the diversion When the liquid is sprayed out after rotating at a high speed, it will be sprayed along the guide surface, so the angle of the guide surface determines the final spray angle of the hollow cone nozzle.
