FIELD: protection devices.
SUBSTANCE: invention relates to protective devices used in explosive and radioactive facilities, such as easy detachable panels and roofs, blast resistant fences and gates, valves of excess pressure. System for onboard safe filling with liquefied gas comprises gas-filling station made a mobile basis of water craft, on which at least one cryogenic tank is installed, cryogenic pump, unit for recording the supplied liquefied gas, a filling pipeline with a shut-off and regulating device for supplying liquefied gas to the liquefied gas storage facility located on a ship, liquid supply line for liquefied gas from a cryogenic tank to the fuel tank of the engine room of the vessel. Water craft is equipped with components for mooring the water craft and mooring components for berthing to shore facilities. Onboard LNG storage is coupled to fuel tank of the engine room by a pipeline with cryogenic pump, in which the ship's fuel system is located, including a ship's container of liquefied natural gas having outside cover of heat-insulated casing with a level indicator that is connected to the cryogenic pipeline via the evaporator refrigerant valve, which, in its turn, is connected to a self-pressurization evaporator. Outlet of the self-pressurization evaporator is connected through gas pipeline with a pressure regulator connected to the onboard tank. Using cryogenic line, onboard tank is connected to A bunkering line through return valve and bunkering sleeve, and also, with production evaporator-gasifier via liquid and vapor phase switching device. Using gas line, onboard tank is connected to B draining line through return valve and bunkering sleeve, and also, with production evaporator-gasifier via liquid and vapor phase switching device. Safety valve with a rupture element, manometer and drain valve are on gas line. Production evaporator-gasifier, which has a “C” coolant inlet and “D” outlet of the coolant, via the main valve, is connected to the ship internal combustion engine, which is connected to the exhaust silencer. Ceiling part of the engine room has an explosion-proof element made in the form of an anti-explosion panel containing metal armored frame with metal reinforced plating and filler-lead, it has four fixed supporting pipes fitted at its ends. In coating of explosive object are rigidly embedded four bearing rods, which are telescopically inserted into fixed branch pipe-support of panel. Filler is composed of air-lead disperse system,wherein lead is made in form of chips. Support rods are made resilient. Extra combined elements damping effect of shock wave are secured to load-bearing bar end faces on the side facing to the metal frame, for example elastic-damping, in the form of an elastic element, for example a conical spring filled with polyurethane, the bottom base of which rests against the stopping sheets and is fixed on them by filling with polyurethane, and the upper base faces towards the armored metal skin.
EFFECT: invention increases reliability of operation of explosion-proof devices during emergency explosion at site and provides return of said structures into initial position after explosion.
