Special opening device for cold aerosol automatic fire extinguishing control system

TL;DR: In this article, a pneumatic valve fixed at the port of a gas storage bottle and a gas storage bottle for opening it was used to drive a fire extinguishing agent in a powder tank.

Abstract: The invention belongs to the fire extinguishing device field, and especially relates to a special opening device for a cold aerosol automatic fire extinguishing control system. The device comprises a pneumatic valve fixed at the port of a gas storage bottle and the gas storage bottle for opening the pneumatic valve, wherein the pneumatic valve is communicated with the gas storage bottle through a gas flow pipeline. The device has the advantages of simple structure, and realization of large opening moment, safety, reliability and long service life through the fire extinguishing implementation via utilizing high-pressure nitrogen in the gas storage bottle to open the gas storage bottle and drive a fire extinguishing agent in a powder tank.
