Abstract
The utility model relates to a special seawater compensator, mainly comprising a corrugated pipe (1) and flanges (2) fixed at two ends of the corrugated pipe (1), inner and outer sides of the corrugated pipe (1) are attached with a layer of rubber (6) respectively, at the same time, each flange (2) is provided with a connecting piece (3) integrated with the flange, a pull rod (4) is arranged between the connecting pieces (3) of two flanges (2, 2), the corrugated pipe is a flexible overpressure-resistant stainless steel corrugated pipe, a vibration-damping rubber pad (5) is arranged at the connecting part of the connecting piece (3) and the pull rod (4). The special seawater compensator has high corrosion resistance, low manufacture cost and prolonged service life, moreover, the operation cost of the pipe is reduced.
Description
Technical field
The utility model relates to a kind of FlexbleJoint, specifically is meant a kind of seawater dedicated compensator.
Background technique
Corrugated expansion joint also is expansion joint, slip joint traditionally, is made up of bellows that constitutes its operative body and annexes such as end pipe, support, flange, conduit; Be that effective dilatation in order to the elastic element that utilizes corrugated expansion joint absorbs pipeline, conduit or the container a kind of compensation device by former thereby the dimensional changes that produces such as expand with heat and contract with cold, belong to a kind of compensating element; Can be to axially, laterally and the absorption of angular displacement, be used for pipeline, equipment and system add thermal walking, mechanical displacement absorbs vibration, reduces noise etc., and is of many uses in modern industry.
Existing compensator, when medium is seawater or piping erection by the sea the time, because bellows all adopts metallic material to be made, bellows very easily occurs corroding and causes the leakage of pipeline medium, and the corrosion-resistant grade of raising bellows, it then is uneconomic promptly using the stainless steel of more high-grade material.
The model utility content
Technical problem to be solved in the utility model provides a kind of seawater dedicated compensator, and it is the decay resistance height not only, and fabricating cost is low, and then has prolonged the working life of compensator, has reduced the operating cost of pipeline.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the seawater dedicated compensator, mainly form by bellows, the flange that is fixed on the bellows two ends, in order to strengthen antiseptic property, inside and outside both sides at described bellows are lined with one deck rubber respectively, simultaneously on each flange, be equipped with the link that is solidified as a whole with it, between the link of two flanges, also be provided with pull bar.
Further, the structure of described two flanges is all identical, and the number of connecting pieces of each flange is more than two.
In order to reach better antiseptic effect, described bellows is a stainless steel flexible pressure-resistant bellows.
In order better to realize also being provided with rubber damping pad in the joint of link and pull bar by the utility model.
To sum up, the beneficial effects of the utility model are: this seawater dedicated compensator, can be widely used in seawater medium or longshore tube equipment, on the inside and outside wall of pipeline, respectively be lined with one deck rubber, can satisfy the demand of seawater corrosion resistance fully, help prolonging the working life of compensator and pipeline, save operating cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structure for amplifying schematic representation of the utility model bellows.
Mark and corresponding component title in the accompanying drawing: 1-bellows; The 2-flange; The 3-link; The 4-pull bar; The 5-rubber damping pad; 6-rubber.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, this seawater dedicated compensator mainly is made up of bellows 1, the flange 2 that is fixed on bellows 1 two ends, and the while is equipped with the link 3 that is solidified as a whole with it on each flange 2, also be provided with pull bar 4 between the link 3 of two flanges 2.Can find out clearly that by Fig. 2 the inside and outside both sides of described bellows 1 are lined with one deck rubber 6 respectively.
The structure of described two flanges 2 is all identical, and the quantity of the link 3 of each flange 2 is more than two; Described bellows is a stainless steel flexible pressure-resistant bellows; And also be provided with rubber damping pad 5 in the joint of link 3 and pull bar 4.
This seawater dedicated compensator, by respectively serving as a contrast the last layer natural rubber at the compensator inner and outer surface, the blocking-up seawater contacts with the direct of corrugated stainless steel tubing, reduces the directly chance of corrosion, prolongs the working life of compensator.Compensator is mainly and ensures axial, horizontal, the angle thermal distortion of pipe safety operation compensation extraction duct; The FlexbleJoint extending amount makes things convenient for the installation and removal of valve pipe; The absorption equipment vibration reduces the influence of vibration equipment to pipeline; Absorb earthquake, earth subsidence amount of deformation to pipeline.
Select for use the material of making bellows should have good plasticity, be convenient to shaping of bellows, and can as flow harden, heat treatment etc., obtain enough hardness and intensity by treatment process subsequently; Have high elastic limit, tensile strength and fatigue strength, guarantee the bellows proper functioning, and good welding performance, satisfy the welding process requirement of bellows in working process; Decay resistance preferably, thus satisfy bellows job requirement under this particular surroundings of seawater.
The most of manufacturers of stainless steel material all adopt Austenitic Stainless Steel, and for the grid of seawater special use, seawater can soak bellows, should consider the material of selecting for use corrosion resistance stronger, as iron-nickel alloy, Langaloy etc.Because this type of material price is higher, when making bellows, we promptly inside and outside the common stainless steel material both sides respectively be lined with one deck natural rubber, make the corrosion resistance of bellows have further raising.
As mentioned above, just can realize the utility model preferably.
Above-mentioned embodiment is a preferred embodiment of the present utility model; can not limit claim of the present utility model; other any change that does not deviate from the technical solution of the utility model and made or other equivalent substitute mode are included within the protection domain of the present utility model.
