HYDRODYNAMIC NONREACTIVE R/TOOLS FOR CLEANING OF SURFACES

摘要

above-water and underwater structures; cleaning tools. SUBSTANCE: proposed tool has housing-handle with working medium supply main channels. Trunk is connected with housing-handle. High-pressure working nozzle is connected with trunk. Tools is provided with guard plate on housing on housing- handle with adapter secured on plate. Hose connects main channels with high- pressure source through adapter. Working medium flow rate regulator with control handle is installed on housing-handle and is connected to main channel. Tip is installed on free end of trunk to form ejector and high-pressure chamber behind trunk cut from side of location of working nozzle relative to trunk. Nozzle is installed on trunk tip. Head with adjusting holes is found on trunk tip. Support clamp is arranged on ejector regulator. Ejector is formed by axially symmetrical through channels made in tip and located around trunk cut. Ejector regulator is made in form of adjusting ring with holes installed for rotation on trunk head. Holes interact with adjusting holes of head. Axis of tool trunk is either straight-line or curved. EFFECT: simplified design, improved reliability, quality and efficiency of operation, enhanced safety of operator and enlarged operating capabilities of tool. 4 cl, 4 dwg
