DRAIN SYSTEM FOR DRAINING A RESERVOIR WITH A FLUID CONTROL SYSTEM OF A TANK CONNECTION VALVE TO A VENT

摘要

This emptying system (50) for emptying at least one tank (30, 32) containing a fluid under pressure comprises, for the or each tank (30, 32), a vent (52) for the evacuation fluid from the tank (30, 32) and a drain valve (54) for connecting the tank (30, 32) to the vent (52). The drainage system (50) further comprises, for the or each discharge valve (54), a member (56) for returning the evacuation valve (54) to its closed configuration, and a system (57) for fluid control for controlling the displacement of the or each discharge valve (54) to its open configuration by the action of an operating fluid on the discharge valve (54). This control system (57) comprises a maneuvering station (58) disposed outside a danger zone around the or each tank (30, 32), and for the or each evacuation valve (54), a fluid conduit (60, 62) fluidly connecting the operating station (58) to the exhaust valve (54). The operating station (58) comprises at least one reversible free connection (64) for connection to the or each fluid line (60, 62) of a device (66) for supplying the control system (57) with fluid maneuvering.
