This firefighting facility is called a suspended dry chemical fire extinguishing device, with a sprinkler-like device on the head and a pressure gauge! When the glass bubble is heated and expands and shatters, the pressure gas inside can be squeezed out of the dry powder to extinguish the fire, which is suitable for places where water can not be used to extinguish the fire, compared with other fire extinguishing systems, the construction is simple and cheap, but the biggest defect is that the dry powder capacity is limited, and it can only be used in places with less fire risk! #How much do you know about fire protection facilities# #Those things in the project# #Breaking the news# #Wonderful pen and flower creation challenge# #Record my 2023# #消防消控操作员 from today#
