Description

Plastic-coated fire hose

Technical field

The utility model relates to fire-fighting equipment technical field, especially a kind of plastic-coated fire hose.

Background technique

Plastic-coated fire hose is the hose for transporting the anti-flaming liquids such as high pressure water or foam.

Currently, traditional plastic-coated fire hose includes by the interior plastic layer set gradually outward and braiding layer, due to braiding Layer weaves unreasonable, so that braiding layer will appear fracture when plastic-coated fire hose is pullled by fire fighter, the braiding layer tension It is poor to pull ability, since braiding layer is broken, will cause plastic layer and ground friction is prone to wear and even galls, lead to water band Leak, so as to shorten service life.On the other hand, the water source that plastic-coated fire hose uses is often high pressure water flow, when passing through Biggish impact force can be generated when plastic-coated fire hose to it, fire fighter is caused to be not easily controlled water spraying direction, to influence Fire-fighting efficiency.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of anti-pull ability is strong, easy Control water spraying direction and the plastic-coated fire hose to prolong the service life.

The technical solution of the utility model is achieved in that a kind of plastic-coated fire hose, including water band body, feature Be: the water band body includes by the interior plastic layer set gradually outward and braiding layer, and the inner surface of the plastic layer is arranged There is axial diversion trench, the braiding layer is woven by synthetic fibers, and the braiding layer includes multiple groups warp and multiple groups weft, Any one group of warp in the multiple groups warp includes the first warp, the second warp, third warp and the 4th warp, the multiple groups Any one group of weft in weft includes the first weft, the second weft, third weft and the 4th weft, any one group of warp Vertical with any one group of weft to be interweaved, the infall of warp and weft connects, first in any one group of warp Warp be respectively placed in the bottom surface of the first weft in any one group of weft, the top surface of the second weft, third weft top surface and the 4th The top surface of weft, the second warp in any one group of warp be respectively placed in the bottom surface of the second weft in any one group of weft, The top surface of first weft, the top surface of third weft and the 4th weft top surface, the third warp point in any one group of warp It is not placed in the bottom surface of third weft in any one group of weft, the top surface of the first weft, the top surface of the second weft and the 4th weft Top surface, the 4th warp in any one group of warp are respectively placed in the bottom surface of the 4th weft, the first latitude in any one group of weft The top surface of line, the top surface of the second weft and third weft top surface.

It is preferred that are as follows: the slot bottom of the diversion trench is arcuate structure.

By using above-mentioned technical proposal, which is woven reasonable, improves the anti-pull ability of braiding layer, so that applying Braiding layer is not in fracture when modeling fire hose is pullled by fire fighter, since braiding layer is not in fracture, eliminates modeling The bed of material and ground friction are prone to wear the possibility even galled, eliminate water band and the possibility of leak occur, to extend plastic-coated The service life of fire hose；It is provided with axial diversion trench in the inner surface of plastic layer, the water in plastic-coated fire hose is risen The effect for having arrived guiding, reduces high-pressure water to the impact force of water band, ensure that fire fighter can readily control water band Water spraying direction, ensure that can accurately be directed at fire extinguishing point, to improve fire-fighting efficiency.

The utility model is further arranged to: being woven with fluorescent belt in the braiding layer.

By using above-mentioned technical proposal, can play a warning role.
