PURPOSE:To enhance the detergency and driving force in superhigh pressure washing of sewers, etc., to improve washing efficiency and to facilitate the curved advance in bends. CONSTITUTION:A superhigh pressure washing nozzle consists of a pipe where the 1st nozzle 3 fitted to the tip of a superhigh pressure hose connected to the superhigh pump and having plural jet holes 3a for jetting obliquely backwards and the 2nd nozzle 7 having plural barkward jet 7a for jetting obliquely backwards and a forward jet hole at the tip are connected in series through a hose 4 for the 2nd nozzle of appropriate length. And more than two nozzles may be used and an oscillating swivel coupling may be interposed between connecting parts for each nozzle. |
