SAFETY SYSTEM FOR GLOBEESHAPED TANK TO BE INSTALLED IN LPG BASE

摘要

PURPOSE:To prevent the pressure-rising in a globe-shaped tank for promoting the safety by exchanging the heat of vapor in the globe-shaped tank highly pressurized in an abnormal time indirectly with the tank liquid of low temperature for liquefaction. CONSTITUTION:For opening and closing a line 16, a pressure controller 17 to catch the pressure variation in a receiver 10 is linked with a valve 18. When the pressure in a globe-shaped tank 3 is risen to rise the pressure in a receiver 10, the valve 18 is automatically opened to form a fluid current running through a line 16. Then, a vapor condenser 9 is worked, and the pressure in the globe-shaped tank 3 is lowered to a fixed for preventing the globe-shaped tank 3 for abnormal rising of pressure.
