Abstract
The utility model provides a wear -resisting high -pressure fire hose, by soft water pipe, the fire hydrant joint of soft water pipe one end and the squirt joint of the other end, still include quick trapping devices, quick trapping devices includes the rigidity drum, the one end of rigidity drum has connecting thread, the identical soft water pipe of rigidity drum internal diameter pressurizes the outer external diameter in back, the soft water pipe of the flexible seal gasket of rigidity drum inside lining is total five layers, outwards be the anticorrosive coating according to the preface from interior, polyurethane manages the layer, on two once organizational structure's machine knit twill weave pipe layer, twill weave pipe layer and polymer wear -resistant coating are knitted to two time last organizational structure's machine. Its advantage has greatly improved the anticorrosive ability of resistance to pressure of product, can bear 6.0MPa's superhigh pressure fire control water source, quick trapping devices can leak the hosepipe part in the very first time that fire hose takes place to leak on stifled, need not look for other kits again.
Description
Technical field
The utility model relates to the flexible pipe with the enhancement Layer embedded in tube wall, relates to hose fitting, espespecially a kind of wear-resisting high pressure fire fighting water-band.
Background technology
In the prior art, fire hose generally arranges a braid outside rubber tube, braid Polyester Yarns, the braiding of polypropylene staple fibre spun yarn silk forms, it has unique feature, with after can again roll, volume is little, lightweight, easy to use, but because outer braid is direct and earth surface, in ground out-of-flatness, when having rough thing, because braid is easy to be worn, so cause product durable not, life-span is shorter, the inwall of rubber tube is also had not have anticorrosive coat, not there is corrosion-resistant function, make the reduced lifetime of product equally, and woven tube is woven structure one on the other, in use its withstand voltage properties is poor, can not high-pressure water in addition, be not suitable for the fire extinguishing of skyscraper, be unfavorable for shortening attack time, cause the loss reduced the person and property.Fire hose many times causes because service time is long, hydraulic pressure is high or be subject to all beyond thought reasons such as percussion wearing and tearing and leaks simultaneously, and this leaks hydrant spraying hydraulic pressure can be caused to reduce, directly affect water spray height and range, have influence on the efficiency of fire suppression, finally have influence on masses suffering from disaster and can property effectively be succoured.When leaking appears in fire hose, the most frequently used craft leakage mending method, is use strap to carry out winding at the place of leaking to tie up, or uses two-sided fastening adhesive tape to bond, but these method effects is unsatisfactory.Therefore, if water-band is leaked by the very first time occurring to leak after fire hose pressurising, part blocks, can prevent this small opening from continuing to expand by high pressure water impact on the one hand, fire-fighting quality and efficiency can be ensured on the other hand, for every minute is striven to obtain in the rescue of masses suffering from disaster and property thereof, complete fire-fighting rescue mission better, this is also that we pay close attention to the problem of solution.
Summary of the invention
For the shortcoming of prior art, the purpose of this utility model is to provide a kind of wear-resisting high pressure fire fighting water-band.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of wear-resisting high pressure fire fighting water-band, by soft water pipe, the fire hydrant joint of soft water pipe one end and the water gun joint composition of the other end, it is characterized in that: also comprise Rapid leakage repairing device, described Rapid leakage repairing device comprises rigid cylinder, there is connecting thread one end of rigid cylinder, rigid cylinder internal diameter coincide external diameter outer after soft water pipe pressurising, the flexible gasket seal of rigid cylinder liner, the ring being respectively provided with a band dentation inside gasket seal two ends is protruding, described rigid cylinder is located on outside soft water pipe, be fixed on water gun joint by connecting thread with suitable being threaded on water gun joint, described soft water pipe has five layers, the woven twill weave tube layer of two undertissue's structures and high molecular abrasion-proof coating in the woven twill weave tube layer, two being from inside to outside sequentially institutional framework once in anticorrosive coat, polyurethane adhesive tube layer, two, in high molecular abrasion-proof coating and described two, once the woven twill weave tube layer of institutional framework is compressed to one, in polyurethane adhesive tube layer and two, once the woven twill weave tube layer of institutional framework is compressed to one.
The beneficial effects of the utility model are: adopt five-layer structure, drastically increase the resistance to pressure antiseptic power of product, the super-pressure fire water supply of 6.0MPa can be born, be mainly used on the above high pressure fire fighting car of city high level fire extinguishing water delivery 300 meters of height, be beneficial to the service life extending product.The very first time that Rapid leakage repairing device can occur to leak at fire hose part of water-band being leaked blocks, other kits need not be found again, namely can prevent this small opening from continuing to expand by high pressure water impact, ensure fire-fighting quality and efficiency, for every minute is striven to obtain in the rescue of masses suffering from disaster and property thereof, complete fire-fighting rescue mission better.Mechanism of the present invention is simple, easy to operate, Be very effective.
When soft water pipe generation water-band is leaked, Rapid leakage repairing device is threadingly unscrewed, make it to be separated with water gun joint, then Rapid leakage repairing device is moved on to leakage area, the ring of a gasket seal wherein band dentation is protruding just crossed over leakage area time, water in cylinder can spill along the breach of boss, along with Rapid leakage repairing device stage casing is close to leakage area, the outside deformation of ring-type of the protruding inner the raised area of ring of the water pressure pushing band dentation of Rapid leakage repairing device inside, after deformation, breach is subject to the shutoff of the ring-type of outer the raised area, equally, the breach of the ring-type of outer the raised area is also subject to the shutoff of the ring-type of inner the raised area, so can realize the perfect Rapid leakage repairing of fire hose.In addition, Rapid leakage repairing device is installed on water gun joint and connects, and can play and prevent the stress of soft water pipe and fire hydrant fast joint or water gun joint junction from concentrating and damaging, serve the object extending the fire hose life-span.
