Problems solved by technology

[0004] The inventor found that when the connecting hoses of the gas-liquid two-phase water mist gun in the prior art are twisted, the two hoses are easy to kink with each other, resulting in taking up too much space; Hoops or cloth covers are cumbersome and add extra cost; hose materials are usually rubber products, and since two hoses are required, both the cost of the hose and the total weight of the hose are relatively high

Abstract

The invention discloses a gas-liquid two-phase flow water mist lance connecting hose and an assembling method thereof. The gas-liquid two-phase flow water mist lance connecting hose comprises a hose body and a hose joint connected with the hose body; the hose body comprises a sealing joint connected with the hose joint, and a first conveying hose and a second conveying hose in mutual embedding; the first conveying hose is positioned on the inner side, is hollow and forms a first fluid passage; the second conveying hose is positioned on the outer side; a second fluid passage is formed in a radial gap between the first conveying hose and the second conveying hose; the sealing joint is provided with a first through hole communicating with the first fluid passage and a second through hole communicating with the second fluid passage; a first outlet communicating with the first through hole and a second outlet communicating with the second through hole are formed in the hose joint are formedin the hose joint; one of the first through hole and the second through hole are formed in the axial direction of the hose body; and the other of the first through hole and the second through hole are formed in the radial direction of the hose body. The gas-liquid two-phase flow water mist lance connecting hose has the advantages of being low in manufacturing cost and convenient to store and transport and has higher promotional value.

Description

technical field [0001] The application relates to the field of fire-fighting equipment, in particular to a gas-liquid two-phase flow water mist gun connecting hose and an assembly method thereof. Background technique [0002] With the improvement of fire protection requirements, the efficient fire extinguishing effect of water mist fire extinguishing technology composed of gas-liquid two-phase flow has attracted people's attention, and the corresponding equipment and products have become the focus of technical research. [0003] Gas-liquid two-phase flow water mist guns are widely used with backpack water mist guns, cart-type water mist guns, and vehicle-mounted water mist guns, especially cart-type and vehicle-mounted water mist guns. The length of the hose used is longer. The length of the trolley-type hose is generally 10 meters, and the length of the vehicle-mounted hose is 25 meters. Some products even need to be customized for 30 meters or even longer. The hose used i...
