PROBLEM TO BE SOLVED: To provide a vaporizer irregular-stop in which the supply of a liquefied gas to the gas supply side is surely stopped at time of the occurance of temperature abnormality or pressure abnormality of an evaporator. SOLUTION: The vaporizer is equipped with a controlling means for closing a vaporization pressure regulation valve 1 when a liquefied gas decompressed by the vaporization pressure regulation valve 1 is vaporized and heated by a heat source 53, such as an electric heater disposed in an evaporator 2, and the temperature or the pressure on the evaporator 2 side is made abnormal. The controlling means is equipped with a pin mechanism 8 for releasing the spring retainer 11 of a spring 12 from a setting position so as to remove the energization force of the spring 12 which opens the valve 17 of the vaporization pressure regulation valve 1 when the temperature or the pressure on the evaporator 2 side is mode abnormal. |
