Rocker nozzle principle
Release time：
2021-09-15
It is in the nozzle above the rocker shaft, set with a front end with a deflector plate (baffle) and guide plate rocker pressure water from the nozzle of the nozzle when sprayed, the deflector plate impact guide plate, so that the rocker arm produces tangential motion force around the cantilever rotation of an angle, and then return under the action of the torsion spring and hit the nozzle, so that the nozzle turn an angle, and so on repeatedly, the nozzle can make a full-circle rotation. If the nozzle is equipped with a limiting device and a reversing mechanism, so that the nozzle in the rotation of a certain angle after the reversal of rotation, you can carry out fan sprinkler irrigation. Suitable for fixed medium pressure sprinkler systems.

Suitable for fixed medium pressure sprinkler systems. Vertical pendulum sprinkler head Using the reaction force generated when the water impacts the deflector at the front of the vertical pendulum arm to make the sprinkler head rotate intermittently, the pendulum arm is rotated by the counterweight at its back end. After a certain angle of rotation of the nozzle, by the yoke roller and limiter with the drive rod to push and pull the nozzle in front of the reversing arm, so that it cuts into or out of the nozzle jet, forcing the nozzle to quickly reverse. This nozzle has the advantages of balanced forces, reliable work balance, long range, large range of flow adjustment, etc., the use of increasingly widespread. However, the required pressure is higher and the structure is more complex.
