Abstract
A kind of flexible conduit with fire protection flame retarding function, comprise joint, body, body described unlike the prior art comprises the flexible inner layer of coextrusion mold and adds the flexible outer layer of fire retardant, described joint comprise with inverted cone bamboo joint type cutting graftage part, the two ends of described body are inserted in described cutting graftage part.Further, described joint is hinge Pa shape joint, and described joint is 20# galvanizing steel or OCr18Ni9 stainless joint.Compared with prior art, the utility model can not only meet assembling and vibration resistance requirement, and pipe has enough pliabilities, and compact structure is elegant in appearance; The more important thing is that there is fabulous fire protection flame retarding, even if it lights in 800 DEG C of flame, also can rapidly from putting out within 5 second time.
Description
Technical field
The utility model relates to flexible conduit, is specifically related to a kind of flexible conduit with fire protection flame retarding function.
Background technique
Flexible conduit, is generally applied in diesel engine.The general material of conventional flex pipeline is nylon, and nylon self incendivity, does not possess fire protection flame retarding function.And some motor is proposing fire prevention and flame-retardancy requirements to each component on it under some workplace.In order to meet the function of its fire protection flame retarding, the heat insulation or fire proofing material of bag one deck outside nylon tube, although do the requirement reaching fire protection flame retarding like this, also increases caliber cross-section area simultaneously usually, and insecure, unsightly, complex operation.
Summary of the invention
In order to solve the problem, the utility model provides a kind of flexible conduit with fire protection flame retarding function.
The technical solution of the utility model is achieved in that a kind of flexible conduit with fire protection flame retarding function, comprise joint 1, body 2, body 2 described unlike the prior art comprises the flexible inner layer 21 of coextrusion mold and adds the flexible outer layer 22 of fire retardant, described joint 1 comprise with inverted cone bamboo joint type cutting graftage part 11, the two ends of described body 2 are inserted in described cutting graftage part 11.
Further, described joint 1 is hinge Pa shape joint, and described joint 1 is 20# galvanizing steel or OCr18Ni9 stainless joint.
Further, the internal layer 21 of described body 2 is nylon layer.
Further, the skin 22 of described body 2 is the heat-resisting oil resistant rubber adding fire retardant, and thickness is 1.0 ~ 1.5mm.
Compared with prior art, the utility model can not only meet assembling and vibration resistance requirement, and pipe has enough pliabilities, and compact structure is elegant in appearance; The more important thing is that there is fabulous fire protection flame retarding, even if it lights in 800 DEG C of flame, also can rapidly from putting out within 5 second time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The sectional view at A-A place in Fig. 2 Fig. 1.
Fig. 3 is the structural representation of the utility model joint.
Embodiment
In order to understand the utility model better, now by reference to the accompanying drawings, embodiment of the present utility model is described in detail.
Have a flexible conduit for fire protection flame retarding function, comprise joint 1, body 2, the tube wall of described body 2 forms the double layer construction of internal layer 21 and outer 22 by two kinds of flexible material co-extrusions, its skin is fire protection flame retarding layer.Described joint 1 is hinge Pa shape joint, and described joint 1 is 20# galvanizing steel or OCr18Ni9 stainless joint.It is that 20# galvanizing steel or OCr18Ni9 stainless joint intensity are good, corrosion-resistant, high temperature resistant, does not burn, can be connected on the parts of motor etc. by hollow bolt; And the connection of this joint and body 2 is grafting, what the grafting part of joint adopted is inverted cone bamboo joint type structure, easily inserts, but is not drawn out easily.The internal layer 21 of described body 2 is nylon layer.The skin 22 of described body 2 is the heat-resisting oil resistant rubber adding fire retardant, and thickness is 1.0 ~ 1.5mm.
Above-mentioned mode of execution is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.The utility model has many aspects can also improve under the prerequisite of overall thought, all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or change for person skilled in the art scholar.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
