Description
Technical field
The utility model belongs to pressure pipeline Element Technology field, more particularly, to a kind of wear-resisting rotation compensation without acceptance of persons
Device, for the compensation of high pressure-temperature heat distribution pipeline, reduces pipe stress.
Background technology
Whirl compensator grows up on the basis of original sleeve expansion joint, and two are needed on heat distribution pipeline
A or three are arranged in groups, formation rotates against extraction duct thermal walking, so as to reduce pipe stress.Since its compensation rate is big,
Be widely used in recent years in city thermal pipe network, but the whirl compensator inner and outer pipes of the prior art rotate against it is steady
Qualitative difference, by pipeline thrust, is also easy to produce not coaxial eccentric rotation, increases rotational resistance, at the same make airtight and watertight padding circumferential by
Power is uneven, causes leakage to fail.Due to the leakage of working media during use, security is low, and must do substantial amounts of maintenance
Work, it is of high cost.With the fast development of concentrated supply of heating in the city, the security performance requirement to whirl compensator is higher and higher, such as
Security performance is high, service life is grown etc..
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, good seal performance, safe and reliable wear-resisting unbiased
Heart whirl compensator, is especially suitable for high pressure-temperature heat distribution pipeline.
The technical solution of the utility model is：A kind of wear-resisting whirl compensator without acceptance of persons of the utility model, including rotation

The rotating inner tube is located in outer tube, and the outer tube and reducing end pipe are affixed, and the L-shaped gland is sleeved on rotation
Turn outside inner tube, and its one end is stretched into outer tube, and the L-shaped gland is fastened with outer tube by bolt assembly；
The rotating inner tube head is equipped with annular outer platform, and sphere, the reducing are set on the outside of the annular outer platform
The inner side of end pipe is equipped with taper surface, and the sphere is contacted with the taper surface in friction is secondary in line.
Preferably, the outer sleeve inner surface is equipped with annular inner convex platform, and the annular inner convex platform stretches into overcoat with L-shaped gland
Combined stuffing is equipped between one end of pipe.
Preferably, on the inside of the annular outer platform ball is equipped between the annular inner convex platform of outer tube.
Preferably, the angle of the taper surface is 120 degree.
Preferably, the inner side of the L-shaped gland on the inner side of outer tube annular inner convex platform with being all provided with fluted, the groove
Inside inlay anti-wearing liner.
Preferably, the anti-wearing liner is red copper set.
Preferably, the outer tube is welded to connect with reducing end pipe gapless fitting.
Preferably, the bolt assembly is equipped with spring washer, and the spring washer keeps L-shaped gland pressure by elastic reaction
Tight integration filler.
The utility model has the advantages and positive effects of：
1st, there is Self-centering Action when sphere and taper surface coordinate, in line contact in pivoting friction pair, can bear compared with
Big rotating torque, while the structure not only has decline of pressure ability, but also have certain sealing effect, so the present invention is especially suitable
Used under the conditions of conjunction high temperature and high pressure condition.
2nd, security performance height, service life length.
