Abstract

The invention relates to a pressure conveying device, in particular to a foam stock solution pressure conveying device, and belongs to the field of fire fighting equipment. The problems that when fire-fight foam solutions are poured into a fire fighting truck, solutions leak due to too high pressure, waste is caused, when the pressure is too low, the pouring efficiency is low, and the situation that fire fighting truck is not filled with the foam solutions is liable to occur are solved. The foam stock solution pressure conveying device comprises a solution outlet valve assembly, a gas inlet valve assembly, a gas inlet pipe, a solution outlet pipe, a foam stock solution barrel, a connecting assembly, a solution outlet pipe and a gas inlet pipe. The solution outlet valve assembly and the gasinlet valve assembly are mounted on the foam stock solution barrel side by side. The solution outlet valve assembly is connected with the gas inlet valve assembly through the connecting assembly. Thesolution outlet pipe is connected with the solution outlet valve assembly. The gas inlet pipe is connected with the gas inlet valve assembly.

Description

Technical field[0001]The invention relates to a pressure conveying device, in particular to a device for pressure conveying foam raw liquid, and belongs to the field of fire fighting equipment.Background technique[0002]Fire-fighting foam liquid is an aqueous film-forming foam fire extinguishing agent, also known as light water foam fire extinguishing agent; it consists of fluorocarbon surfactants, fluorine-free surfactants (carbon-chlorine surfactants or silicone surfactants) and improved foam Performance additives (foam stabilizer, antifreeze, cosolvent and thickener, etc.) and water composition. When the fire-fighting foam liquid is poured into the fire truck, excessive pressure will cause liquid leakage and waste. Too little pressure not only has low filling efficiency, but also easily leads to dissatisfaction with the foam liquid in the fire truck. Therefore, there is an urgent need for an infusion device that facilitates pressure control Pour fire fighting foam liquid into the ...
