Ensure that floating piston can be moved up and down smoothly.
It is equipped with location hole at the top of the guide shaft, mounting portion is equipped at the top of the upper bracket, is equipped in mounting portion bottom
With the positioning pin of location hole cooperation.Be inserted into the location hole at the top of guide shaft by positioning pin, realize that the activity of guide shaft is fixed, it is convenient with
Change guide shaft and floating ball piston, guarantee convenient for safeguarding.
The fin is horizontal arc plates.The water flow for hitting fin can be made to form parabolic to splash down, improve water
The uniformity of wandering cloth.
It is equipped with horizontal flanging at the top of the inlet channel, is equipped at the top of the uniformly distributed water sprinkler and is fastened on horizontal fold
The flanging of side bottom.Fast and easy connection setting.
It is arc transition between the inlet channel and the horizontal flanging.The water flow be conducive in water pond is fallen.
The utility model has the advantages that: automatic change water spray when variation in water pressure may be implemented, it is equal to ensure to spray
It is even, guarantee that spray area is constant, to improve radiating efficiency.
