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 delivery device, in particular to a device for pressure delivery of foam stock solution, which belongs to the field of fire-fighting equipment. Background technique [0002] Firefighting 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. When the fire-fighting foam liquid is poured into the fire truck, the pressure is too high and the liquid will leak, resulting in waste. If the pressure is too low, not only the pouring efficiency is low, but also the foam liquid in the fire truck is likely to be dissatisfied. Therefore, an infusion device that is easy to control the pressure is urgently needed. Fill the fire fig...
