Abstract
The invention discloses an expandable rubber short tube comprising a pipeline body. The side wall the pipeline body after being expanded is a rectangular rubber sheet; reinforcing convex rings are respectively arranged on two sides of the rectangular rubber sheet; lug plate-shaped fasteners are arranged at two ends of the rectangular rubber sheet and provided with connecting threaded holes which are mutually matched; the reinforcing convex rings are positioned at two ends of the pipeline body after the rectangular rubber sheet encircles to form a pipeline body; and the lug plate-shaped fasteners are positioned on two sides a joint of of the pipeline body after the rectangular rubber sheet encircles to form the pipeline body. The lug plate-shaped fasteners contain metal plates wrapped by rubber. The expandable rubber short tube is a shallow arc rubber sheet after being expanded, can be greatly deformed during installation, wrapped on steel tubes at two ends, fastened by bolts in the lug plate-shaped fasteners, and realizes the connection among tubes without flange connection. Thus the invention can be conveniently assembled and disassembled, and can be operated in a limited space.
Description
Technical field
The present invention relates to a kind of conveying rubber short tube, specifically a kind of expandable rubber short tube that is used for increasing the pipeline flexibility between the two joint steel pipes that is installed on.
Background technique
Be installed on transfer line as the sebific duct between the dredging transfer line two joint steel pipes, general all by means of being with the flange that connects short tube to be connected with adjacent conduit.Screw is arranged on the flange, corresponding mutually with the adjacent channel flange screw, with bolt.If the steel pipe before and after the sebific duct is fixing, apart from less, surrounding space is also less, be installed in the flanged (FLGD) short sebific duct of 1 joint between the two joint steel pipes, and is just relatively more difficult.Not only in default of the space of operation, also there is connectivity problem in this.Can there be certain tolerance in the manufacturing of sebific duct.Because the both sides steel pipe all is fixed, for example at cabin, its tube pitch is from being definite value, will have contradiction with the length tolerance of sebific duct.Even in tolerance range, if sebific duct length less than definite value, then gap between pipe may occur and cause leakage; If sebific duct length greater than definite value, then may be difficult to install.
Summary of the invention
For overcoming the deficiency that prior art exists, the object of the present invention is to provide a kind of expandable rubber short tube.This rubber hose quality softness, shape can change, and does not need just can carry out being connected of tube and tube with bolt by flange, thereby mounts and dismounts very convenient.
The objective of the invention is to be achieved through the following technical solutions:
A kind of expandable rubber short tube is characterized in that: this rubber short tube comprises pipeline body, and it is the rectangle offset plate that this pipeline body launches rear sidewall, is equipped with the reinforcing bulge loop in the both sides of rectangle offset plate; Be provided with otic placode shape fastener at the two ends of rectangle offset plate, on otic placode shape fastener, be provided with the connection screw that cooperatively interacts; Described reinforcing bulge loop is positioned at the two ends of pipeline body after the rectangle offset plate surrounds into pipeline body; Described otic placode shape fastener is positioned at the seam both sides of pipeline body after the rectangle offset plate surrounds into pipeline body.
Among the present invention, described pipeline body comprises inner glue layer, fibercord enhancement layer and outer glue-line, and described inner glue layer, fibercord enhancement layer and outer glue-line extend to the joint of two otic placode shape fasteners.
In the otic placode shape fastener of the seam both sides of pipeline body, be provided with 1 ~ 6 sheet metal, this sheet metal bury in inner glue layer and outside between the glue-line.
Be provided with 4-8 the corresponding connection screw of arranging on otic placode shape fastener, this connects screw and connects inner glue layer, fibercord enhancement layer, outer glue-line and sheet metal.On surface treated sheet metal, scribble the adhesive of band polar bond.
Compared with prior art, the present invention is deployable to be shallow arcuation offset plate, can make moderate finite deformation when mounted, is wrapped on the steel pipe at two ends, fastening with otic placode shape fastener inner bolt again.Expandable rubber short tube quality softness of the present invention, shape can change, and does not carry out being connected of tube and tube by flange with bolt, thereby mounts and dismounts very conveniently, is applicable under the condition of limited space and operates.
Description of drawings

Fig. 2 is a profile schematic representation of the present invention.
Embodiment
A kind of expandable rubber flexible pipe of the present invention, see Fig. 1 and Fig. 2, it comprises one section rubber tubing body 1, and it is the rectangle offset plate that this pipeline body 1 launches rear sidewall, because through mould sulfuration typing, pipeline body 1 launches the offset plate that the back becomes to show slightly shallow arcuation to this pipeline body 1.Respectively there is the reinforcing bulge loop 2 of 1 road through molded vulcanization typing at pipeline body 1 two ends, with the intensity that increases pipe ends and property very.Because through mould sulfuration typing, the above-mentioned offset plate that shows slightly arcuation that has launched can be curled into one section complete cylindric pipeline during use, be wrapped on the steel pipe of two ends, forms pipeline with this.
There is otic placode shape fastener 3 the seam both sides that offset plate is curled into cylindric pipeline body 1, and 4-8 that is provided with on otic placode shape fastener 3 in correspondence with each other connects screw 4, with the bolton that runs through, thereby makes the seam crossing densification, stop the interior liquid material of pipeline to leak.Pipeline body 1 tube wall divides three levels, i.e. inner glue layer 5, outer glue-line 7 and bury therebetween fibercord enhancement layer 6.Fibercord enhancement layer 6 is made up of multilayer rubber fiber cord fabric.By vulcanization crosslinking, inner glue layer 5, fibercord enhancement layer 6, outer glue-line 7 are combined into an integral body, bear the sebific duct operating pressure.Reinforcing bulge loop 2 at the sebific duct two ends is connected with the middle part in the otic placode shape fastener 3 that stitches both sides, all has the glue-line and the enhancement layer cord fabric that extend from tube wall to distribute, to increase the strength and stiffness of these two parts.In otic placode shape fastener 3, also contain 1 ~ 6 sheet metal 8 that passes through surface treatment and scribble adhesive, they in sulfidation with physical force and chemical force and rubber strong bonded, make this part not only flexible but also rigidity arranged, to strengthen fastening strength, make the seam crossing sealing, leak when being unlikely to work.
The present invention expands into shallow arcuation offset plate, can make moderate finite deformation when mounted, is wrapped on the steel pipe at two ends, fastening with otic placode shape fastener inner bolt again, do not carry out being connected of tube and tube with bolt, thereby mount and dismount very conveniently, be applicable under the condition of limited space and operate by flange.
