WATER FLOW REGULATOR IN PRESSURE PIPELINE

摘要

FIELD: machine building. ^ SUBSTANCE: invention refers to regulating devices on water outlets of storage dams. The water flow regulator consists of cone gate (10) installed in an outlet opening of pressure pipeline (5) and of follow-up automatic hydro-drive (17) of the gate facilitating control of degree of opening of drawdown aperture (15) of the gate. The pressure pipeline is laid inside the gallery of the water outlet in the body of the dam. The hydro-drive consists of group of hydro-cylinders (18) and of a vertical piezo-metric chamber filled with working fluid (hydraulic oil). Rods (20) of hydro-cylinders are attached to movable cylinder branch (14) of the conic gate; working chambers (21) facilitate decreased degree of drawdown aperture (15) opening by means of pipes (22) connected to Pitot tubes; also these working chambers are communicated with flow-through cavity (16) of the gate. Working chambers (23) ensure increased degree of drawdown aperture (15) opening and are communicated with the piezo-metric chamber. Capacity of the piezo-metric chamber within limits of calculated range of fluctuations of working fluid levels and dimensions of its cross section within limits of this range at various levels facilitate regulation of degree of opening of the drawdown aperture of the gate. ^ EFFECT: ensuring automatic regulation of water flow with simple and reliable drive. ^ 12 cl, 10 dwg
