PURPOSE:To enable to supply LPG economically by a method wherein natural evaporation and forced evaporation are combined and used effectively in the method of supplying the LPG recieved in a tank. CONSTITUTION:A gas phase line (A) is constituted by a method wherein a switching valve 3, opening and closing the valve thereof automatically by a preset pressure, and a pressure regulator 4, keeping the exit side pressure of a pipe 2 at a predetermined value, are connected to the intermediate part of the pipe 2 opening at the gas phase part (a) of a reservoir 1 sequentially. A liquid phase line (B) is formed by a method wherein a evaporator 6 and a pressure regulator 7 are connected to a pipe 5 opening at the lower bottom of the liquid phase part (b) of the reservoir 1. Both of the lines (A), (B) are communicated with a feeding main tube 8 respectively. The LPG evaporated naturally in the reservoir is utilized preferentially through the gas phase line (A) usually and the insufficient part of the LPG is supplemented by the LPG forcibly evaporated in the liquid line (B). |
