FIELD: hydraulic equipment, particularly to drain water from tailing pits, for closed drainage systems formed in zones characterized by severe climatic conditions. ^ SUBSTANCE: spillaway comprises service water vessel, shutoff member made as lower water level regulator arranged in discharge pipeline, upper water level sensor and magnet, which cooperates with magnetic mass when shutoff member is in its closed position. Float-type lower water level control member is installed from discharge pipeline interior side and is used as heat insulation means. Upper water level sensor is made as float and connected to shutoff member by means of vertically-aligned adjusting rod, which regulates upper water level. Magnetic mass is located on lateral pipeline. Magnet is installed on shutoff member. ^ EFFECT: increased leakage prevention, elimination of service vessel cooling and, as a result, extended field of application. ^ 1 dwg |
