Abstract
The utility model discloses a universal spherical compensator, which comprises a shell, an inlet valve, spherical shoes, a spherical body, an inner sleeve, a ribbed plate and packing. The large-end inner chamber of the shell is formed by two symmetrically-placed spherical shoes and forms a chamber for containing the packing. The inlet valve is evenly distributed on the large-end outer wall of the shell and is fixedly connected at the position corresponding to the packing chamber. The spherical shoes and the spherical body are matched in clearance. The packing is filled into the packing chamber from the inlet valve to rotatably seal the spherical body and the shell. The evenly arranged half-moon-shaped ribbed plate is fixedly connected on the inner spherical surface of the spherical body and then the two ends of the spherical body are fixedly connected with the inner sleeve into a whole body. The utility model has the advantages that the rigidity of the spherical body is obviously increased because the ribbed plate is arranged, the deformation resistance is improved and the pressure resistance of the product is promoted.
Description
Technical field
The utility model relates to a kind of compensation of pipeline device, particularly a kind of compensation of pipeline device with spherical rotational structure, and this device utilizes spherical structure three-dimensional rotation characteristic, and the displacement of institute's distribution pipes is compensated.
Background technique
Heat distribution pipe network is an indispensable part in manufacturing industry such as electric power, metallurgy, petrochemical industry and the urban heat supplying engineering.During the heat distribution pipe network operation,,, heat distribution pipe network and support are caused damage, even damage although piping displacement belongs to normal physical phenomenon because of the medium temperature or the variation in pressure of carrying produces corresponding displacement.How the extraction duct displacement is the key of engineering design, and prior art normal employing by the bellow type hinge expansion joint in heat distribution pipe network formed the zigzag thbe joint, utilizes the expansion joint expansion performance to do the compensation of piping displacement.Because the structural limitations of bellows expansion joint, its compensation ability is less, and the ripple tube wall is thin, and carrying High Temperature High Pressure ability is also relatively poor, and deformation resistance is big.Above not enough Security and the Economy that directly influences the hot pipe network operation.In recent years, adopt the spherical compensator of rotatable compensation in the increasing heat distribution pipe network engineering.The spherical compensator of prior art mainly utilizes spherical structure three-dimensional rotation characteristic, and the displacement amount of institute's distribution pipes is compensated.But the spheroid of prior art spherical compensator is a single layer structure, and is yielding at the condition of high voltage lower sphere, and the spheroid distortion descends the spherical compensator sealability, causes economic loss.
The model utility content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of reinforcement sphere structure, and the universal spherical compensator non-deformability of using this structure is strong, and sealing configuration is reliable, security of operation.
The utility model is achieved through the following technical solutions technical goal.
The universal spherical compensator, it comprises housing, feeding valve, ball watt, spheroid, interior cover, floor and filler.Described housing is a main component, two ring balls that its big end inner chamber is put by symmetry watt are formed the cavity of splendid attire filler, be distributed on the fixedly connected feeding valve in corresponding packing cavity body position on the big end outer wall of housing, ball watt and spheroid Spielpassung, filler is filled between housing and the spheroid and constitutes sealing configuration.Its improvements are: the fixedly connected semilune floor of pressing the five equilibrium setting of described spheroid inner ball surface, the spheroid two ends are fixedly connected into interior cover left end.
As further improvement of the utility model: with outer surface of spheroid hard chromium plating and polishing, to improve the wear-resisting property of spheroid.Semilune floor length that the spheroid inner ball surface is fixedly connected and interior cover are axially in the same way.
The utility model compared with prior art has following good effect:
1, the semilune floor that fixedly connected five equilibrium is put on sphere inner wall is simple in structure, easy to manufacture;
2, the spheroid that contains the strengthening rib structure, in interlock the body two ends good rigidly of receiving, non-deformability is strong, the following working pressure of ability 5MPa;
3, sphere structure rotates flexibly, satisfies the requirement of heat distribution pipe network nose balance, and is little to the fixed support active force.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the transverse sectional view of the built-in floor of spheroid.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Universal spherical compensator shown in the drawings, it comprises housing 1, feeding valve 2, ball watts 3, spheroid 4, interior cover 5, floor 6 and filler 7.Main component housing 1 is interior hollow structure, and two ends, the left and right sides are respectively equipped with through hole, the feeding valve 2 of uniform fixedly connected plug screw structure on the right-hand member outer wall, and feeding valve 2 communicates with housing 1.Two ring balls that housing 1 right-hand member inner chamber is put by symmetry watts 3 are formed the cavity of splendid attire filler 7, and ball watts 3 and spheroid 4 Spielpassung are filled between housing 1 and the spheroid 4 from the filler 7 of feeding valve 2 injections and constitute sealing configuration.Specialization of the present utility model is, in spheroid 4 inner ball surface of thin-slab structure, connects the semilune floor 6 of press the five equilibrium setting along interior cover 5 axial restraints, and then spheroid 4 two ends are fixedlyed connected with interior cover 5 is integral.The rigidity that remarkable increase spheroid 4 is set of floor 6 improves non-deformability, promotes the withstand voltage properties of product.
As further technological improvement, with spheroid 4 outer surface chromium plating and polishing, can significantly improve the working life of product, improved the condition of relatively rotating, reduce the compensation resistance.
