Abstract
The utility model discloses a kind of high-pressure anti-wear erosion line with rubber expansion joint, it is characterized in that it includes bellows (1), all weld with flange (4) at the two ends of described bellows (1), the body inner side of bellows (1) is provided with abrasive rubber pipe (3), the two ends of described abrasive rubber pipe (3) extend to described flange (4) and locate, and the madial wall of bellows (1) and flange (4) is all enveloped.The utility model is simple and practical, is using, and expansion joint is without abnormal deformation, and media flow is steady, and the safe operation cycle is long.
Description
Technical field
The utility model relates to a kind of expansion joint, and it is applied to nonferrous smelting and precious metal refines in the medium high-pressure service pump connecting tubes such as ore pulp conventional in industry, mud, coal ash paste.
Background technique
At home and abroad nonferrous smelting and precious metal refine in industry, in the import and export pipeline of some equipment (as high-pressure service pump), medium mostly is ore pulp, mud, coal ash paste, often contains high-sulfur or the very strong component of other corrosivity in this class medium, and piping design pressure is up to more than 8MPa.This just require expansion joint that equipment imports and exports bear under high-pressure situations can xegregating unit vibration, can absorb again pipeline axially and lateral displacement.Be applied at present expansion joint structure in these equipment and be bellows two ends and be to take over welding, take over and flange welding again, in the inner side of bellows, be provided with inside lining sleeve, internal lining pipe welds with above-mentioned adapter.Inside lining sleeve in this structure plays guide functions, although can avoid the wearing and tearing of medium to bellows, cannot avoid Korrosionsmedium to enter bellows inwall, uses expansion joint to reduce time safety period because bellows is corroded.
Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of simple and practical, media flow is steady, the high-pressure anti-wear erosion line with rubber expansion joint that the safe operation cycle is long.
The technical solution adopted in the utility model is as follows:
A kind of high-pressure anti-wear erosion line with rubber expansion joint, it is characterized in that it includes bellows, the two ends of described bellows all and flange welding, the body inner side of bellows is provided with abrasive rubber pipe, the two ends of described abrasive rubber pipe extend to described flange, and the madial wall of bellows and flange is all enveloped.
The body outside of described bellows is provided with whole armouring ring.
The outer side wall lines of described abrasive rubber pipe and described bellows bellows-shaped match.
Described whole armouring is equipped with a plurality of, and they are all in the ripple trough in described bellows body outside.
The beneficial effects of the utility model have:
Simple and practical, using, expansion joint is without abnormal deformation, and media flow is steady, and the safe operation cycle is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, it includes bellows 1 the utility model, all weld with flange 4 at the two ends of bellows 1, in the situation that expansion joint overall length is limited, bellows 1 directly welds with flange 4, can increase the wave number of bellows 1, improve bellows compensate for displacement (particularly lateral displacement) and absorb the ability of vibration, reduce axial and lateral stiffness power to equipment and support bracket fastened thrust.Bellows 1 directly welds with flange 4, and two end flange 4 have played the reinforing function as corrugated tube end armouring ring simultaneously, and reduce expansion joint circumferential weld number.The body inner side of the utility model bellows 1 is provided with abrasive rubber pipe 3; the two ends of abrasive rubber pipe 3 extend to flange 4 places; and the madial wall of bellows 1 and flange 4 is all enveloped; both can protect bellows 1 to avoid Mediawear; can make again bellows 1 and aggressive medium isolation, make thin wall multi-layer bellows avoid the erosion of aggressive medium.The outer side wall lines of abrasive rubber pipe 3 and bellows 1 bellows-shaped match, and both are in conjunction with tight.Abrasive rubber pipe 3 not only can bear the erosion of ore pulp medium, has certain flexibility simultaneously, can be out of shape with bellows change in displacement.Body outside at bellows 1 is provided with whole armouring ring 2, and whole armouring ring 2 is provided with a plurality of, and they are all in the ripple trough in described bellows 1 body outside.2 reinforing functions of whole armouring ring, guarantee to expand and energy-conservationly under condition of high voltage, work reliable and stablely.
The whole armouring ring 2 of the utility model embeds trough when bellows 1 shaped by fluid pressure as shaping die, abrasive rubber pipe 3 bellows 1, whole armouring ring 2 and flange 4 moulding and welding connect and pressure testing complete after again integral body be lining into, between the medium that makes to have abrasion and corrosion and thin-wall corrugated tube and flange, isolate completely.
The undeclared part relating in the utility model is same as the prior art.
