NONREACTIVE HYDRODYNAMIC TOOL FOR SURFACE CLEANING

摘要

The invention relates to the techniques of hydrodynamic cleaning of underwater surfaces of various facilities. The invention makes it possible to improve the service performance of a nonreactive hydrodynamic surface cleaning tool. The inventive tool is comprised of a body with handle (1) containing channels (2) for feeding a working fluid. The barrel (3) is connected to the body with handle (1) and to a working jet (4). A protective bar (5) and a connector (6) are mounted on the body with handle (1). Said channels (2) communicate with a high-pressure source through said connector (6). The body with the handle (1) is provided with a working fluid flow regulator (8) which comprises a lever (9). The free end of the barrel (3) comprises a mouthpiece (10). The nozzle (4) is mounted on said mouthpiece (10). A high pressure chamber is mounted behind the face of the barrel (3). A nozzle mounted on the mouthpiece (10) comprises control openings. An ejector is formed by crossing channels made around the face of the barrel (3). The nozzle comprises an ejector regulator having the shape of a control ring, which includes openings interacting with the control openings of the nozzle. A support bracket is mounted on the ejector regulator. The axis (20) of the barrel (3) can follow a straight line or a curve. <IMAGE>
