JPS5759653A - Injection nozzle for wash water - Google Patents

Abstract

PURPOSE: To remove the fouling of a wall surface simply through the spraying of a small amount of high pressure water by specifying the area of an injection hole with a small diameter of a front surface of an opening section of a nose of a water supply passage and axially mounting a cutwater rotary plate with a specified shape into said opening section.

CONSTITUTION: With the injection holes 4 formed to a nozzle plate 2 screwed onto the front surface of the opening section 3 of the nose of the water supply passage 1, diameters are 0.5W3.0mm, and total opening areas are 0.005W0.1% to the total area of the plate 2. The cutwater rotary plate 5 with V-shaped water-permeable notch section pairs 7, inclines 61, 62, which are shaped by mutually inclining the backs of sections partitioned by the pairs to the reverse sides, and a through-hole 8 at a central section is axially mounted to a lower end of a supporting shaft 9 rotatably in the front of the water passage 1 in the opening section 3. When water from household water service, etc. is stored in a tank and charged into high pressure water and poured against the backs of the plate 5, water flows to the sections 7 from the surfaces 61, 62, and the plate 5 is turned in the opposite direction. One part of the water is divided when it passes through the sections 7, and the wall surface is subject to the continuous strikes of high pressure waterdrops divided.
