Abstract
The utility model discloses a composite bushing compensator, it includes casing, filler, bolt, gland and inner tube. The inner pipe is sleeved with the outer shell, the outer sleeve is sleeved on the outer wall of the concave section in the middle section of the inner pipe, and the inner pipe is fixedly connected with the outer sleeve. The right end of the inner pipe is sleeved with an inner retainer ring and welded into a whole, and a steel ball is assembled in a concave annular groove in the middle section of the outer wall of the inner retainer ring and is in rolling contact fit with an inner hole of the shell. The utility model provides an outer tube is the refined seamless steel pipe of stainless steel thin wall, its glossy outer wall and the sealed cooperation of packing, and the motion resistance is little, wearing and tearing are few, sealed, corrosion resistance is strong, seal structure long service life. The utility model has simple structure and easy manufacture, and is particularly suitable for manufacturing the high-pressure large-caliber sleeve compensator.
Description
Technical field
The utility model relates to a kind of compensation of pipeline device, and the utility model relates to a kind of sleeve compensator specifically.
Background technique
Variation because of medium temperature during the heat distribution pipe network operation causes thermal distortion, the thermal distortion form of expression of heat distribution pipe network mainly is the pipeline axial elongation, the pipeline axial elongation produces end thrust and has destructiveness, so necessary compensation of pipeline device will be set to absorb thermal distortion in heat distribution pipe network.The compensation of pipeline device of using in the engineering has multiple structural type, and wherein sleeve compensator obtains widespread usage because of characteristics such as simple in structure, that pressure-bearing is high, the nose balance amount is big.But, the sleeve compensator of prior art, particularly the heavy caliber sleeve compensator because of the outer wall of inner tube machining after roughness difficulty reach designing requirement, coarse relatively outer wall of inner tube has bigger motion wearing and tearing to the sealing material that matches, easily cause the sealability of sealing configuration to descend, this defective has reduced the using effect of sleeve compensator.
The model utility content
The utility model is primarily aimed at the deficiency that the motion wearing and tearing of prior art sealing configuration are big, sealing life is short, propose a kind of simple in structure, make easily, sealing configuration motion wearing and tearing are little, sealing life is long composite bushing compensator.
The utility model is achieved through the following technical solutions technical goal.
The composite bushing compensator, it comprises housing, filler, bolt, gland and interior pipe.The fixedly connected inner shield ring of pipe right-hand member in described, equipped steel ball in the inner shield ring outer wall spill annular groove.Its improvements are: pipe concave section, stage casing outer wall suit outer sleeve in described, and interior pipe is fixedlyed connected with outer sleeve, and outer sleeve cooperates with packing seal.
In the said structure on the outer wall of inner tube outer sleeve of suit be the refining seamless steel pipe of a kind of stainless steel thin-wall, it is little that the outer sleeve that outer wall is smooth and packing seal routing motion wear and tear, good sealing effect, corrosion resistance is strong.
The utility model compared with prior art has following good effect:
1, suit outer sleeve on outer wall of inner tube, simple in structure, make easily;
2, cooperate with packing seal with the smooth outer sleeve of outer wall, resistance to motion is little, wearing and tearing less, tight, the sealing configuration long service life of sealing;
3, corrosion resistance is strong.
Description of drawings
Accompanying drawing is the utility model structural profile schematic representation.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Composite bushing compensator shown in the drawings, it comprises housing 1, filler 2, bolt 3, gland 4 and interior pipe 5.Pipe 5 and shell 1 fit mutually in described, interior pipe concave section, 5 stage casing outer wall suit outer sleeve 5.1, in pipe 5 fixedly connected with outer sleeve 5.1, present embodiment outer sleeve 5.1 is the refining seamless steel pipes of stainless steel thin-wall, outer sleeve about 5.1 ends and interior pipe 5 achieve a fixed connection by welding.In pipe 5 right-hand member suit inner shield rings 5.3 and being welded to each other be integral equipped steel ball 5.2 and shell 1 endoporus rolling contact matching in the inner shield ring 5.3 outer wall stage casing spill annular grooves.The utility model is sealed and matched with smooth outer sleeve of outer wall 5.1 and filler 2, resistance to motion is little, wearing and tearing less, sealing is tight, corrosion-resistant, the sealing configuration long service life.
Claims (2)
1, a kind of composite bushing compensator, it comprises housing (1), filler (2), bolt (3), gland (4) and interior pipe (5); The pipe fixedly connected inner shield ring of (5) right-hand member (5.3) in described, equipped steel ball (5.2) in inner shield ring (5.3) the outer wall spill annular groove, it is characterized in that: pipe (5) concave section, stage casing outer wall suit outer sleeve (5.1) in described, interior pipe (5) is fixedlyed connected with outer sleeve (5.1), and outer sleeve (5.1) is sealed and matched with filler (2).
