Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fire extinguishing device, especially to a water inlet mixed type fire extinguishing agent storage device and oil gas gathering and transferring fire extinguishing system. BACKGROUND

[0002] When the conventional fire extinguishing agent storage tank supplies fire extinguishing agent to generate foam, the mixing ratio of the foam fire extinguishing agent and water can deviate from the predetermined value due to improper operation or equipment failure, thereby affecting the fire extinguishing effect.
