The shape of most nozzle holes is round. This is because the circle is the easiest to control its dimensional accuracy and surface roughness during processing, and the processing technology is the simplest compared to other shapes, so our nozzles generally adopt a circular jet Hole (except for special nozzles), but the circular jet hole is destined to only spray cylindrical, so when we design the nozzle, we will change the internal structure or external structure of the nozzle, so that the nozzle can spray other shapes to meet various Different needs.

The structure of the cylindrical nozzle is the simplest. Its interior is connected to the jet hole by a conical hole. The shape of the jet is cylindrical, and the theoretical diameter of the cylinder is the same as the diameter of the jet hole. This kind of nozzle has a huge impact force and is among all nozzle structures. The jet shape with the greatest impact. But its shortcomings are also obvious, the jet coverage area is small, and the cross section is similar to a point.

In order to make the spray coverage area larger, we install a cross-shaped rotating blade (X-type) inside the nozzle. After the liquid enters the nozzle, it rotates according to the set route and angular velocity, and then ejects from the circular hole to form Full cone spray shape.

Hollow cone nozzles are even simpler. A cavity is created inside the nozzle body for liquid to rotate. The liquid enters the cavity along one side of the cavity, and is ejected from the circular hole after rotating along the cavity to form a hollow cone. Jet shape.

The flat fan nozzle first makes a spherical hole, and then makes a V-shaped groove on the outer surface, so that the nozzle hole forms an olive-shaped nozzle hole with a width in the middle and a narrow side on both sides. The liquid is squeezed from the nozzle hole by the inner wall. It is sprayed out to form a flat fan-shaped spray shape.

The square nozzle is based on the full cone nozzle. The outer shape of the nozzle is changed to make the circular hole form an uneven surface. The time and angular velocity of the liquid leaving the nozzle during spraying will be different, resulting in a square cross-section. Jet shape. Or on the basis of the full cone nozzle, the spray hole is made into an ellipse, then the spray shape will become an ellipse.

It can be seen that the shape of the spray hole of almost all nozzles is based on a circle, and accessories are added to the outside or cut from the outside according to a specific spray shape, so as to form different spray shapes. This also leads to another result, that is, the simpler the fluid movement inside the nozzle, the stronger the jet impact force (cylindrical nozzle). Conversely, the more complex the fluid movement inside the nozzle, the weaker the impact force the nozzle can generate. (Full cone nozzle).
