Abstract
The utility model provides a displacement compensation pipe, includes the bellows, the both ends of bellows respectively with take over one end sealing connection, one of them take over the outside and be fixed with the crown plate with the bellows junction, the bellows overcoat has a protective sheath, protective sheath one end is fixed mutually with the outer edge of crown plate, the axial extension of bellows is followed to the other end, makes the wave number of the bellows that is located outside the protective sheath less than 12. The displacement compensation pipe has a simple structure, the protective sleeve is arranged outside the corrugated pipe, most of the corrugated pipe is positioned in the protective sleeve, the wave number of the corrugated pipe positioned outside the protective sleeve is less than 12, the stability is good, the safety and the reliability are realized, and the maintenance frequency is reduced. Because the corrugated pipe in the protective sleeve does not have the instability problem, the wave number of the corrugated pipe in the protective sleeve can be more, the displacement compensation amount is large, the fixed support is saved, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of shift compensation pipe, be used for the pipeline connection pipeline is carried out bit shift compensation.
Background technique
Therefore bellows bending easily, elongation, compression are widely used in pipeline connects, so that pipeline is carried out bit shift compensation.But because stability, the wave number of existing bellows can only be provided with at most about 10, many will loss of stability.Owing to bend angle, the elongation compression factor of bellows are all restricted, the bit shift compensation amount of therefore existing bellows is little, need use a plurality of bellowss just can reach bit shift compensation during as installed to pipeline, bellows is installed needs fixed support to support, this fixed support costs an arm and a leg, and therefore causes cost very high.At present some bellows has adopted rock-steady structure, but structure more complicated all, and make bellows bending, elongate flexible being restricted, be difficult for realizing crooked and elongate flexiblely, still fail to solve the little problem of bit shift compensation amount.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of simple in structure, good stability, bit shift compensation amount big, save fixed support, shift compensation pipe that cost is low.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of shift compensation pipe; comprise bellows; the two ends of described bellows are tightly connected with adapter one end respectively; one of them is taken over the outside and is being fixed with ring flat-plate with the bellows joint; bellows is with a protective casing outward; the outer of protective casing one end and ring flat-plate fixes, and the other end extends axially along bellows, makes the wave number that is positioned at the outer bellows of protective casing less than 12.
Shift compensation pipe of the present invention wherein is fixed with the sleeve pipe otic placode respectively in the both sides of protective casing, is fixed with the adapter otic placode respectively in the both sides of another adapter, is fixed with pull bar between sleeve pipe otic placode and the adapter otic placode.
Shift compensation pipe of the present invention, the bottom of wherein said ring flat-plate is provided with gusset.
Shift compensation pipe of the present invention, wherein said protective casing is provided with the hole.
The wave number of the bellows in the shift compensation pipe of the present invention, wherein said protective casing is 8-200.
Shift compensation pipe of the present invention, the wave number of the bellows that wherein said protective casing is outer is 5.
Shift compensation pipe of the present invention, wherein said protective casing are cylinder type or square type; The corrugated portion of described bellows should be cylinder type or square type mutually.
Shift compensation pipe of the present invention, wherein said protective casing is made by metallic material.
Shift compensation pipe of the present invention, wherein said bellows is made by stainless steel material.
Shift compensation pipe of the present invention is simple in structure, and protective casing is set outside bellows, makes the major part of bellows be positioned at protective casing, and the wave number that is positioned at the outer bellows of protective casing is less than 12, and good stability is safe and reliable, has reduced maintenance frequency.Because there is not the problem of unstability in the bellows that is positioned at protective casing, the wave number of the bellows in the protective casing can be established a plurality of, and the bit shift compensation amount is big, and has saved fixed support, has reduced cost.
Description of drawings
Fig. 1 is the structural representation of shift compensation pipe of the present invention.
Embodiment
As shown in Figure 1, shift compensation pipe of the present invention comprises bellows 5, the two ends of bellows 5 are connected with adapter 1 one end welded seals respectively, one of them is taken over 1 outside and is being fixed with ring flat-plate 3 with bellows 5 joints, and the bottom of ring flat-plate 3 is welded with gusset 2, to increase stability.Be with a protective casing 4 outside the bellows 5, the outer of protective casing 4 one ends and ring flat-plate 3 fixes, and the other end extends axially along bellows 5, makes the wave number that is positioned at the bellows 5 outside the protective casing 4 less than 12, has guaranteed the stability of bellows.In the present embodiment be 5.Protective casing 4 can be made as cylinder type, square type or other shapes, corresponding cylinder type, square type or other shapes of being made as of the corrugated portion of bellows 5.Protective casing 4 can be made by metallic material.Bellows 5 can be made by metallic material or rubber, preferred stainless steel material.For convenient transportation, can take over 1 the fixing respectively otic placode 8 of taking in both sides, fixed drawing-rod 7 between sleeve pipe otic placode 6 and the adapter otic placode 8 at another at the both sides of protective casing 4 difference fixed sleeving otic placode 6.According to actual needs, the wave number of the bellows 5 in the protective casing 4 can establish minority also can establish a plurality of, as 8-200.Because protective casing 4 is arranged outside the bellows 5, therefore when establishing a plurality of wave number, bellows can loss of stability.The wave number of the bellows 5 in protective casing 4 more for a long time; hole 9 can be set on protective casing 4, and when carrying high-temperature gas or high-temp liquid, the pressure of gas can increase between protective casing 4 and the bellows 5; gas can flow out from hole 9, with the pressure of 5 of balanced protection sleeve pipe 4 and bellowss.
The wall thickness of bellows 5, internal diameter, length, wave height, the pitch of waves and waveform are all unrestricted.The bellows 5 that is positioned at protective casing 4 is mainly based on axial displacement, is positioned at that protective casing 4 outer bellowss 5 can carry out axially, horizontal or angular displacement, and bend angle is unrestricted.
Above-described embodiment is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technological scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
