Description
Technical field
The present invention relates to specially, for the pulverized fuel ash tank car supports the use, to be used for carrying the rubber hose of the particles such as cement, pulverized fuel ash, breeze, specifically a kind of Novel tanker special steel wire is wound around discharge pipe.
Background technique
Known dry-mixed mortar tank car discharge pipe on the market has the product of two kinds of structures at present.The one, the folder stringing, its structure is hose lining, layer of cloth (reinforced layer) and outer compound protective layer.The 2nd, the braided steel wire pipe, its structure is hose lining, steel wire Steel Wire Braid (reinforced layer) and outer compound protective layer.The shortcoming of folder stringing is the anti-positive/negative-pressure ability of body, and body easily flattens; Although and the braided steel wire pipe has improved anti-positive/negative-pressure ability, the steel wire of using due to reinforced layer is with knitting machine, two strands of steel wires directly to be intersected and form, and between steel wire, is directly to contact, and there is no bonding layer.Therefore between steel wire, there is no combination force, so braided steel wire itself very easily produces displacement, thereby can cause body deformation and delamination.Because braided steel wire is to be formed by metal monofilament direct organization, therefore can cause the rigidity of body strong simultaneously, it is large that bending radius becomes, inconvenient operation, and be difficult for recovering after flattening under external force, thereby affected use.
In addition, because using scope is more and more extensive, market is more and more higher for product requirement.Such as the conveying of high temperature powder, the product that makes loss of properties on aging is aging, embrittlement at high temperature very soon, finally causes using.
Summary of the invention
In order to make product can bear positive/negative-pressure, again can be easy to operate, and also have certain recovery capability, also wanting simultaneously can be high temperature resistant, the invention provides a kind of Novel tanker special steel wire and is wound around discharge pipe.The existing very strong positive/negative-pressure tolerance of this product, simultaneously flexible again, easy to operate, and also have stronger recovery capability, and can under hot environment, use.
The present invention adopts following technological scheme to realize: a kind of Novel tanker special steel wire is wound around discharge pipe, comprise body, described body comprises tube core, interior glue wearing layer, middle reinforced layer and outer compound protective layer, in the middle of described, strengthen comprising steel wire floor and middle glue bond layer, described steel wire floor comprises the first steel wire floor and the second steel wire floor; Described interior glue wearing layer, middle glue bond layer and outer compound protective layer respectively by interior film, in film and outer film be entwined; Described steel wire floor is become by Steel cord winding face.
The beneficial effect that the present invention produces is that this product had both guaranteed the anti-positive/negative-pressure ability of body, had also improved flexibility and the recovery capability of body simultaneously, with more tolerating high temperature, thereby had improved operational condition, had improved the using scope of product.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, be elaborated:
Fig. 1 is pipe structure figure.
Fig. 2 is the Steel cord sectional drawing
Fig. 3 is structure of steel wire figure
In figure, 1, interior glue wearing layer 2, the first steel wire floor 3, middle glue bond layer 4, the second steel wire floor 5, outer compound protective layer 6, tube core 7, steel wire
Embodiment
As shown in the figure, a kind of Novel tanker special steel wire is wound around discharge pipe, comprise body, described body comprises tube core 6, interior glue wearing layer 1, middle reinforced layer and outer compound protective layer 5, in the middle of described, strengthen comprising steel wire floor and middle glue bond layer 3, described steel wire floor comprises the first steel wire floor 2 and the second steel wire floor 4; Described interior glue wearing layer 1, middle glue bond layer 3 and outer compound protective layer 5 respectively by interior film, in film and outer film be entwined;
Described steel wire floor is entwined by Steel cord;
Described Steel cord is become by seven strands of steel wires, 7 winding faces;
The diameter of described steel wire 7 is 0.5mm-0.8mm;
The winding direction of the Steel cord of described the first steel wire floor 2 and the second steel wire floor 4 is opposite;
Described outer compound protective layer 5 outsides are wound with one deck water cloth.
Concrete making step of the present invention is as follows:
As shown in Figure 2 and Figure 3, being the structure of Steel Wire Strand cord, is mutually to be intertwined according to several angle by seven single steel wire 7, has so just increased the flexibility of steel wire, does not also reduce the intensity of steel wire simultaneously.
At first as requested, prepare the Steel Wire Strand cord of respective diameters; Prepare interior film, middle film and the outer film of respective thickness, note, interior film is thicker than middle film and outer film.
As shown in Figure 1, the mode be wound around of at first interior film being take is fixed on diameter on the tube core 6 of 4 cun, glue wearing layer 1 in forming; Then ready Steel Wire Strand cord is wrapped on interior glue wearing layer 1 with the balance angle, forms the first steel wire floor 2; Then more ready middle film is wrapped in to the outside of the first steel wire floor 2, glue bond layer 3 in formation; Middle glue bond layer 3 outside are wound around the second steel wire floor 4 according to the balance angle again, and attention is reverse with the first steel wire floor 2; Finally ready outer film closely is wrapped in to the outside of the second steel wire floor 4, forms outer compound protective layer 5.So far, pipe forming is complete, is wound around last layer water cloth, enters sulfurizing pot vulcanization.In high temperature resistant test, interior glue wearing layer 1 is selected the heat resistant rubber material, can under 150 degree, use for a long time, still keeps the physical property of 90% left and right.
Existing discharge pipe, body adopt cord or braided steel wire all more unilateral, can't reach technique effect; Therefore we adopt Steel cord, are entwined by the steel wire 7 of seven gangs of diameter 0.5mm-0.8mm; The intensity that had both retained steel wire itself, reduced again the intrinsic rigidity of steel wire, just in time made up the deficiency of above-mentioned two kinds of reinforcing materials; The Steel Wire Strand spiral rubber hose substitutes the single steel wire braided construction hose, makes product have brute force and crooking ability; Through static pressure test, the body ability to bear has reached 20mpa, has far surpassed the working pressure of product; And the bending radius of body also reached one meter, facilitated operation.Simultaneously, when body was subject to rolling, due to the rigidity reduction of steel wire, flexible reinforced, can substantially recover former state, thereby improve utilization efficiency.
