Conveying device for conveying fire-fighting foam liquid

Abstract

The invention relates to the technical field of fire-fighting equipment, and discloses a conveying device for conveying fire-fighting foam liquid. The conveying device comprises a liquid storage cylinder, wherein the top of the liquid storage cylinder fixedly communicates with a transition pipe; a matched L-shaped inserting pipe is inserted into the transition pipe; a first sealing ring matched with the transition pipe is fixedly connected to the outer pipe wall of the L-shaped inserting pipe in a sleeving mode; one end, far away from the transition pipe, of the L-shaped inserting pipe fixedlycommunicates with an air inlet hose; an external thread is arranged on the outer pipe wall, close to the top end, of the transition pipe; moreover, a rotating cylinder is arranged on the transition pipe in a sleeving mode; an internal thread matched with the external thread is arranged on the inner cylinder wall of the rotating cylinder; moreover, the rotating cylinder is in threaded connection with the transition pipe; a matched ball bearing is fixedly installed on the inner cylinder wall, close to the top end, of the rotating cylinder; and the L-shaped inserting pipe penetrates through theball bearing. According to the conveying device for conveying the fire-fighting foam liquid, the fire-fighting foam liquid can be conveniently and rapidly conveyed into a storage tank of a fire-fighting truck, so that time-consuming and labor-consuming manual carrying is avoided, and then the conveying efficiency of the fire-fighting foam liquid is effectively improved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a delivery equipment for delivering fire-fighting foam liquid. Background technique [0002] Fire-fighting foam liquid, also known as aqueous film-forming foam fire extinguishing agent or light water foam fire extinguishing agent, is composed of fluorocarbon surfactants, fluorine-free surfactants and additives for modifying foam properties, such as foam stabilizers, antifreeze agents, auxiliary Solvents and thickeners and other substances are composed of water. When the fire-fighting foam liquid and water are mixed through the proportional mixing device, a large amount of foam will be produced. When the spraying device is sprayed onto the burning oil surface, the moisture in the foam chromatography can form a well-closed water film on the fuel surface. , to play the role of isolating fuel and air, through the double function of foam and protective film, it can qu...
