Nozzles are an important accessory for PVC lay flat hose. There are many kinds of nozzles, among which rocker nozzles are used more frequently.
When the pressure water of the rocker arm with a deflector (baffle) and a deflector is ejected from the nozzle of the nozzle, the deflector is impacted by the deflector so that the rocker arm generates tangential motion force to rotate around the cantilever at an angle, and then returns to the nozzle under the action of the torsion spring and impacts the nozzle, so that the nozzle rotates at an angle, and sprays repeatedly. The head can rotate in a full circle. If a limit device and a reversing mechanism are installed on the sprinkler head to make the nozzle rotate reversely at a certain angle, the fan-shaped sprinkler irrigation can be carried out.
When the PVC lay flat hose nozzle rotates at a certain angle, the reverse arm in front of the nozzle is pushed and pulled by the yoke roller and the limiter through the transmission rod to cut in or leave the nozzle jet and force the nozzle to reverse rapidly. PVC lay flat hose reminds the sprinkler that it has the advantages of balanced force, reliable work balance, long range, large flow regulation range, etc., and is used more and more widely. But the pressure is high and the structure is complex.
