Hollow cone nozzle spray pattern

The structure of the hollow cone nozzle is roughly divided into two types. The most common one is that the nozzle has a circular swirl cavity inside, and the water inlet is tangent to the swirl cavity, so that when the liquid enters the nozzle through high pressure, it will produce high-speed rotation. The liquid flows, and then is ejected along the hole wall through the nozzle hole smaller than the swirl cavity. 涡流喷嘴

The other is that the liquid spreads along the pre-manufactured conical surface. This solution is more suitable for applications with large-angle hollow cones.
