LP GAS SUPPLY SYSTEM WITH VAPORIZER/AND VAPORIZER HAVING LIQUID PHASE-GAS PHASE CHANGEOVER FUNCTION USED THEREIN

摘要

PURPOSE:To simplify LP gas supply pipeline by providing a vaporizer connected through a liquid phase-gas phase changeover mechanism to two systems of gas pipeline portions communicating with a liquid phase portion or a gas phase portion of a LP gas container and supplying gas to the terminal side through the vaporizer. CONSTITUTION:The respective liquid phase side gas pipes 1a are united as used and spare side pipeline 2 in one line through an automatic liquid selector valve 3 and connected to the liquid phase side of a liquid phase-gas phase changeover mechanism 10. Liquid is supplied through the mechanism to a vaporizer 12 and gasified there. On the other hand, gas phase side gas pipes 1b are united in one gas phase side gas pipeline 6 together with spare and used LP gas containers and connected to the gas phase side of the liquid phase-gas phase changeover mechanism 10. Then, the output terminal of the vaporizer 12 is connected to the two-stage secondary regulator 8 side and connected to the terminal gas appliance through the regulator.
