Abstract
The invention discloses a novel high-temperature and high-pressure bellow compensator which comprises a left connection pipe (1), a bellow left connection pipe (2), a bellow (3), a bellow right connection pipe (4), an inner casing pipe (5), sliding bearings (6) with the self-lubricating characteristic and a middle ring (7). The novel high-temperature and high-pressure bellow compensator is characterized in that the inner surface of the bellow left connection pipe (2), an annular inner convex ring, the outer surface of the inner casing pipe (5) and an annular outer convex ring form a sliding bearing bush; the two sliding bearings (6) with the self-lubricating characteristic are clamped on two sides of the middle ring (7), inserted into the bellow left connection pipe (2) and sleeved on the inner casing pipe (5); and the bellow left connection pipe (2), the inner casing pipe (5), the two sliding bearings (6) with the self-lubricating characteristic and the middle ring (7) form a sliding bearing supporting friction pair structure. A bellow deforms slightly in the radial direction under the lateral torque action, thus the capacity of resisting radial bending deflection of the compensator is enhanced.
Description
Technical field
The present invention relates to a kind of High Temperature High Pressure corrugated expansion joint, belong to the technical field of piping element.
Background technique
High Temperature High Pressure corrugated expansion joint is the pith in high temperature, high pressure pipe network.The leakage of High Temperature High Pressure corrugated expansion joint, the defect such as break all can bring to pipe network system that either large or small operation is undesired even causes major break down.By the corrugated expansion joint analysis to inefficacy, corrugated expansion joint is due to a variety of causes off-design position, existing compensator friction pair respective outer side edges gap is larger, cause bellows to be subject to lateral torsion effect, bellows part is subject to radially assymmetrical deformation stress, bellows whole geometry axle center is bent, and the working state of bellows and each ripple joint internal stress exceeds the operating range of design, is to produce that corrugated expansion joint breaks, the reason of explosion even.
Summary of the invention
The object of the invention is to propose a kind of new type high temperature high-pressure bellows compensator, this compensator feature is the friction pair structure that bellows passes on left the sliding bearing formation sliding bearing support with self-lubricating property, reduce existing corrugated expansion joint friction pair respective outer side edges gap, make bellows and inner sleeve keep coaxial, inner sleeve is no longer structurally single-ended suspension, when being subject to lateral torsion, corrugated expansion joint does the used time, bellows and inner sleeve bear the bending deflection effect of stress that lateral torsion produces jointly, thereby greatly strengthen the intensity of bellows, improve the diastrophic ability in compensator opposing bellows whole geometry axle center, ensure that bellows is operated in the operating range of design.High Temperature High Pressure corrugated expansion joint also can be used in common heating network.
Its structural representation of compensator that the present invention proposes as shown in Figure 1.
The technical solution used in the present invention is:
A kind of High Temperature High Pressure corrugated expansion joint, is made up of left adapter 1, the left adapter 2 of bellows, bellows 3, the right adapter 4 of bellows, inner sleeve 5, the sliding bearing 6 with self-lubricating property, central ring 7.The left adapter 2 of bellows, bellows 3, the right adapter 4 of bellows are connected and are fixedly linked successively, and be all enclosed within on inner sleeve 5, left adapter 1 is fixedly linked with left adapter 2 left ends of bellows, the right adapter 4 of bellows is fixedly set on inner sleeve 5, and inner sleeve 5, the right adapter 4 of bellows, bellows 3, the left adapter 2 of bellows are and are welded to connect with left adapter 1.The left adapter 2 internal surface low order ends of bellows have a ring-like internal projecting ring, inner sleeve 5 outer surface high order ends have a ring-like outer bulge loop, it is characterized in that: left adapter 2 internal surfaces of bellows and ring-like internal projecting ring, inner sleeve 5 outer surfaces and ring-like outer bulge loop form plain bearing bush, two sliding bearings 6 with self-lubricating property ring 7 both sides that are clipped in the middle, be inserted in the left adapter 2 of bellows, be enclosed within on inner sleeve 5, the left adapter 2 of bellows, inner sleeve 5, two have the sliding bearing 6 of self-lubricating property, central ring 7 forms corrugated expansion joint sliding bearing and supports friction pair structure.Sliding bearing 6 outer surface diameter with self-lubricating property are greater than the diameter of the internal projecting ring internal surface of left adapter 2 low order ends of bellows, and sliding bearing 6 inner surface diameter with self-lubricating property are less than the diameter of the outer bulge loop of inner sleeve 5 high order ends outside face.
