Fire detection tube used for automatic fire extinguishing device and the automatic fire extinguishing device

摘要

The present invention provides an automatic fire extinguishing device that can detect a fire at the temperature lower than 120 degrees Celsius and that can be installed for a long term in a state of maintenance-free.;The fire extinguishing device consists of a pressure resistant container filled with the extinguishant and the pressurization agent, the container valve attached to the opening of the pressure resistant container, the fire detection tube connected to the container valve. And the fire detection tube is formed with the lamination of the tubular base resin layer and the gas barrier layer, the base resin layer is made of the thermoplastic resin and the gas barrier layer is made of ethylene vinyl alcohol copolymer resin (EVOH resin).
