EMERGENCY SHUT-OFF DEVICES OF LPG TANK LORRY

摘要

The present invention relates to the emergency shut-off device of the liquefied petroleum gas tank to block the gas discharge with radio or temperature sensing when a fire occurs in the LPG tank,; The LPG is based on the lower portion of the charge tank 60 is mounted on the vehicle shut-off valve 62 and the liquid shut-off valve 64 is mounted, the group shut-off valve 62. The compressor 68 is equipped with a gas tube ( 72) is connected to the storage tank 70 through, the liquid shut-off valve 64 is in the LPG supply to the storage tank 70 through the liquid tube (74),; Opening and closing of the valves (62, 64) is made by the motor 80, the motor 80 is controlled by manual switch 87, a temperature sensor (88) or remote control system.; Thus, it is possible to block the valve as the temperature sensor and the remote control system, there is an effect that it is made up of strongly motor heat block the fire valve effectively and reliably as a valve block unit.
