Nozzle inside

The internal structure of the nozzle is related to the jet type of the nozzle. Different jet shapes have different internal structures. For example, the internal structure of the hollow cone nozzle is mostly a vortex cavity, and the hole where the liquid enters the cavity is tangent to the circular surface of the swirl wall. , The liquid will form a high-speed rotating liquid flow after entering the swirl chamber, and the huge centrifugal force will throw the liquid out of the narrow spray hole and spray it out in a fixed direction, forming a hollow cone spray shape.

The flat fan nozzle is generally squeezed by the two semi-circular walls inside the hole, so that the liquid is squeezed from the two sides to the middle, so the cross section of the spray shape is approximately a straight line, because it has a strong impact force. , So this nozzle is often used to clean the surface of the object.

The internal structure of the full cone nozzle is much more complicated. The internal swirl blade of the full cone nozzle is generally cross-shaped (X-shaped), and the liquid entering the nozzle will form a rotating liquid flow with different angular speeds under the action of the swirl blade. , The angle formed by the jet with high angular velocity is large, and the angle formed by the jet with low angular velocity is small, so that a full cone shape is formed, and the droplet distribution at any point inside the cone is uniform.

The above are the internal structures and principles of three common types of nozzles. In addition, there are hybrid, jet, guide surface and other structures. Different structures are suitable for different spray requirements. You are welcome to contact us for more information about nozzle structures. And applied technical information.
