Title:
VERY LOW TEMPERATURE LIQUEFIED GAS TANK OF SPACESHIP
Document Type and Number:
Japanese Patent JPS5917100
Kind Code:
A
Abstract:
PURPOSE:To supply a low flow rate of gas in a gaseous state under a weightless condition, by mounting a heat source for boosting the inner pressure of a tank and a pressure detector in a storage tank, and meanwhile, constituting a pressure regulating tank such that the pressure therein can be maintained at a value within an allowable range. CONSTITUTION:A temperature signal by a temperature detector 11 is fed back, and a pressure regulating tank is maintained at a given temperature higher than the liquefying temperature of gas through the working of a heater 9. A pressure is monitored by a pressure detector 10, and when the pressure in a pressure regulating tank attains an allowable lower limit, a secondary valve 13 is closed, a primary valve 12 is opened, gas, in which a liquid phase 2 and an air phase 3 are mixed, is guided from a storage tank 1, and when the pressure detector 10 finds that the pressure in the pressure regulating tank attains the allowable upper limit, the primary valve 12 is closed. In order to increase the internal pressure of the storage tank 1 to a value higher than the allowable upper limit pressure of a pressure regulating tank 7, the internal pressure is increased to a given value by heating the storage tank by means of a heat source 4 for boosting a pressure.
