Abstract
The utility model relates to a positive pressure ventilation rubber flexible tube used underground for coal mines, which comprises a tubular main body and is characterized in that the tubular main body comprises an outer rubber layer, a framework layer and an inner rubber layer which are sequentially connected. The positive pressure ventilation rubber flexible tube has the advantages of being excellent in inflaming retarding performance and anti-static performance, good in pressure bearing capability, large in safety factor and suitable for severe underground environment.
Description
Technical field
The utility model relates to a kind of positive pressure ventilation rubber hose, is used for the ventilation under the coal mine and carries general non-corrosiveness medium.
Background technique
The ventilation rubber hose that colliery of the prior art is used in the concrete process of using, exists bearing capacity and flame-retardant and anti-static performance poor, and especially at abominable subsurface environment, safety coefficient can not get guaranteeing, has certain potential safety hazard.
Summary of the invention
For overcoming the defective of existing technology, the utility model provides a kind of flame-retardant and anti-static performance excellence, bearing capacity is good, safety factor is big, and flexibility is good, is applicable to the underground mine use positive pressure ventilation rubber hose of more abominable subsurface environment simultaneously.The technological scheme of the utility model is: a kind of underground mine use positive pressure ventilation rubber hose; Comprise tubular body; It is characterized in that: described tubular body comprises outer glue-line, framework layer and inner glue layer, and described outer glue-line, framework layer are connected with inner glue layer successively in order.
The caliber of described outer glue-line, framework layer and inner glue layer successively shortens, and forms stepped.
Described framework layer is made by the high strength cord.
The utility model has the advantages that: have the excellent fire retardant anti-static electricity property, bearing capacity is good, and safety factor is big, and flexibility is good, is applicable to more abominable subsurface environment.
Description of drawings
Fig. 1 is the agent structure schematic representation of the utility model;
Embodiment
Referring to Fig. 1; The utility model relates to a kind of underground mine use positive pressure ventilation rubber hose, comprises tubular body 4, and described tubular body 4 comprises outer glue-line 1, framework layer 2 and inner glue layer 3; Described outer glue-line 1, framework layer 2 are connected with inner glue layer 3 successively in order; Mode through pressing or bonding between every layer links together, and the caliber of described outer glue-line 1, framework layer 2 and inner glue layer 3 successively shortens, and forms stepped.
After described outer glue-line 1 was mainly synthesized through common process according to the ratio of 2:1 by butadiene-styrene rubber and carbon black with inner glue layer 3, processing and fabricating formed, and described framework layer 2 is made by the high strength cord, like high strength nylon cord or polyester cord.
