Abstract
The utility model provides a glass reinforced plastic and rubber composite slurry delivery pipe. At least one steel ring is radially arranged at each of the joints of steel flanges and glass reinforced plastic outer layers on two sides of the composite slurry delivery pipe respectively to form the composite slurry delivery pipe on the basis of the prior art. The composite slurry delivery pipe has the advantages of existing composite slurry delivery pipes, such as light pipe weight, high pressure resistance, corrosion resistance, abrasion resistance and high shock resistance, and further resistance between the steel flanges and the glass reinforced plastic outer layers is strengthened by the aid of the steel rings, so that composite strength between the steel flanges and the glass reinforced plastic outer layers can be effectively increased, and the steel flanges and the glass reinforced plastic outer layers can be firmly integrated. The glass reinforced plastic and rubber composite slurry delivery pipe has the advantages of simple structure, economy, practicality, stability in performance and easiness in population and the like.
Description
Technical field
The utility model relates to a kind of slurry pipeline, particularly relates to a kind of dredging works land slurry pipeline.
Background technique
For a long time, the spoil disposal slurry terrestrial pipeline that domestic dredging industry is used generally all adopts steel pipe.Steel pipe weight is big, perishable, not wear-resisting.Owing to reasons such as corrosions, China will lose up to ten thousand tons of steel every year, but also need carry out the maintenance of pipeline, not only increase maintenance expenses, also increase unnecessary trouble simultaneously.For understanding this problem of rhymed formula, part unit introduces West Germany's pvc pipe material production line, though can effectively reduce weight by the product of this production line production, improves the rust resistance of tubing, remains some problems in actual use and can't solve.Flange arrangement can't be made into as the body point of attachment, the grafting form can only be formed.This will make troubles to installation, and sealing effect is also bad.And when serviceability temperature is lower than below 0 ℃ impact resistance with wear no resistance, easily cracked.Therefore, this product can only use in lower working pressure and certain temperature range.The rubber combined slurry pipeline of a kind of glass fibre reinforced plastics is disclosed in the China Patent No. 93229266.6, it is combined by inner rubber layer, bonding layer, glass fibre reinforced plastics skin and steel flange, the impact that it utilizes inner rubber layer to bear media such as stone, gravel, silt tube wall is caused, wearing and tearing, cutting etc., the glass fibre reinforced plastics skin is born body internal pressure and external environment anti-aging effect, in order to guarantee favorable sealing property, this slurry transportation pipe joint has been taked the steel flange rubber sealing structure.Yet because steel flange and the outer field combination of glass fibre reinforced plastics of this delivery pipe is gluing form, body will be subjected to axial pulling force under normal operation, easily makes between glass fibre reinforced plastics skin and the steel flange to break away from, thereby causes whole pipe disconnection and can't use.
Summary of the invention
The purpose of this utility model is to provide a kind of glass fibre reinforced plastics rubber combined slurry pipeline, mainly is to solve between the glass fibre reinforced plastics skin that exists in the prior art and the steel flange to break away from, thereby causes whole pipe to disconnect and the problem that can't use.
The technical solution of the utility model is as described below: this model utility comprises inner rubber layer, bonding layer, glass fibre reinforced plastics skin, steel flange, bonding layer and sealing line, mainly is by each radially is provided with a steel loop at least and realizes in the steel flange at these delivery pipe two ends and the outer junction of glass fibre reinforced plastics.
The utility model is an improved composite sludge delivery pipe on the prior art basis, it has possessed the advantage of existing composite sludge delivery pipe, have light, the withstand voltage height of body, corrosion-resistant, wear-resistant and impact resistance, can make simultaneously the bigger resistance of generation between steel flange and the glass fibre reinforced plastics skin again by the setting of steel loop, effectively increase the adhesive strength of the outer interlayer of steel flange and glass fibre reinforced plastics with this, make both firmly form an integral body, reliably realize goal of the invention.And has an advantage such as the suitable popularization of economical and practical, stable performance simple in structure.
Below with reference to accompanying drawing the utility model is described in detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
The rubber combined slurry pipeline of a kind of glass fibre reinforced plastics shown in Figure 1 is improved a kind of composite sludge delivery pipe on the basis of existing composite sludge delivery pipe.It is made up of inner rubber layer 1, intermediate adhesion layer 2, glass fibre reinforced plastics skin 3, steel flange 4, bonding layer 5, sealing line 6 and steel loop 7.Inner rubber layer 1 and intermediate adhesion layer 2 are made, and in sulfidation, are precast rubber sealing line 6 by compounding rubber processing, sulfuration.Glass fibre reinforced plastics skin 3 by glass fiber yarn or glass fiber cloth insulating varnish after, be wrapped in intermediate adhesion layer 2 surfaces, make through room curing.The body two ends are steel flanges 4, and each radially is provided with a steel loop 7 at least in outer 3 junctions of steel flange 4 and glass fibre reinforced plastics.As outer 3 junctions of steel flange among Fig. 14 and glass fibre reinforced plastics two steel loops 7 are set respectively.Increase steel flange 4 and glass fibre reinforced plastics outer 3 and even overall mechanical strength of the present utility model with this.Steel flange 4 combines closely with glass fibre reinforced plastics outer 3 and inner rubber layer 1.Inner rubber layer 1 relies on bonding layer 5 to combine with steel flange 4 and forms one.
During actual the use, with screw steel flange 4 is coupled to each other the formation pipeline between each slurry pipeline.Mud can in inner rubber layer 1 surface and body, press and the effect of water under move, finish the task of slurry transportation.
