Abstract
A plane duplex expansion joint is provided which comprises a bellows, connection pipes at two ends, an oriented protection sleeve, a retaining ring and a resistance sleeve. The utility model is characterized in that one end of the oriented protection sleeve connects the connection pipe at same end by a welded oriented baffle and the other end of the oriented protection sleeve is welded to a retaining ring the inner side of which is equipped an elliptic guidance baffle welded to the connection pipe at the other end. The utility model possesses advantages to absorb both an axial displacement and a horizontal displacement and reduce manufacture costs.
Description
Technical field
The utility model belongs to a kind of pipe network expansion joint, particularly a kind of plane compound expansion joint.
Background technique
In design of pipe networks such as heating power in the past, to compare with L, the Z type pipeline of rectilinear duct, 90 ° of corners, general corner is bigger especially more or less thorny greater than 120 ° pipeline.For pipe condition as shown in Figure 3, do not satisfy when compensation naturally and to compensate when requiring, and adopt the WY profile shaft also to can't resolve problem to expansion joint, if because the WY profile shaft is arranged on the AO section to expansion joint, except that WY axial expansion joint does not absorb the lateral displacement of OB section, also make the stressing conditions of fixed support A, the B no good cake that becomes.Need 2 with the lateral mode expansion joint, need 3, often make unhelpful the increasing of expansion joint, and then increased engineering cost with angle type expansion joint.
The model utility content
The purpose of this utility model provides a kind of plane compound expansion joint, can absorption axes to absorbing lateral displacement again, reduce engineering cost.
The purpose of this utility model is achieved by the following technical solution: it comprises bellows, two pipe nipples, directional protection cover, back-up ring and antidrag sleeve; it is characterized in that: the directed baffle plate of welding between an end of directional protection cover and the pipe nipple; the other end welding back-up ring of directional protection cover; in the inboard of back-up ring the ellipse deflector apron is set, deflector apron is welded on the other end and takes over.
The utility model has the advantages that: can absorption axes to absorbing lateral displacement again, reduce engineering cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
To be existing corner be provided with view greater than 120 ° pipeline to Fig. 3.
Embodiment
See Fig. 1,2, concrete structure is as follows: it is by original axialmode product improvement: connect two pipe nipples 1 respectively at the two ends of bellows 4, at the inside of bellows 4 assembling antidrag sleeve 3, the medium of antidrag sleeve 3 when being fit to transverse movement is along rounding off.Outer set at bellows 4 sets to protecting jacket 5; one end of directional protection cover 5 is by pipe nipple 1 welding therewith of directed baffle plate 2; the other end welding back-up ring 7 of directional protection cover 5 is provided with ellipse deflector apron 6 in the inboard of back-up ring 7, and ellipse deflector apron 6 is welded on the other end and takes on 1.Because the internal diameter horizontal and directional protection cover 5 of ellipse deflector apron 6 has respective clearance H, therefore can absorb lateral displacement.
