Where is the difference between a pressure reservoir and a gas bottle in a dry fire extinguisher?
As a matter of fact, a pressure extinguisher is adopted at present. Because the gas bottle fire extinguisher is dangerous, it may cause gas to explode in a small cylinder and enter a large bottle without pressure.
A pressure extinguisher: a fire extinguisher driven by compressed air or a fire agent and vapor pressure stored in the same container of a fire extinguisher. Outside view, in fact, there is only one big bottle, next to no small bottle.
Cylinder fire extinguisher: a fire extinguisher driven by a compressed gas or liquefied gas released from a storage tank of a fire extinguisher. Outside, there is a large bottle with a small bottle beside it.
