Abstract
The invention discloses a spherical compensator for thermal compensation of a pipeline. The spherical compensator comprises a shell and a sphere. A liquid inlet hole and a first groove are formed in the shell. A pressing plate is connected to the shell. A conical through hole is formed in the pressing plate. The sphere comprises a sphere head section and a mounting section. The sphere head section penetrates through the conical through hole and extends into the first groove. The sphere can move in the conical through hole around the center of the sphere head section in a reciprocating mode. The sphere head section is provided with a second groove. The mounting section is provided with a liquid outlet hole. The spherical compensator has the effects that by changing the size of the conical through hole in the pressing plate, the range in which the sphere moves around the center of the sphere head section in the reciprocating mode can be changed, namely the compensation range of the spherical compensator is changed, and thus the compensation range of the spherical compensator is wide, and the compensation requirement for heat expansion and cold contraction of the pipeline can be fully met.
Description
Technical field
The present invention relates to compensator, be specially a kind of spherical compensator for pipe thermal compensation.
Background technique
Compensator is also called expansion bend or slip joint, expansion joint, is mainly used in compensating pipeline by temperature variation and expanding with heat and contract with cold of producing.If pipeline can not completely freely expand or shrink during temperature variation, in pipeline, thermal stress will be produced.Must consider this stress in piping design, otherwise it may cause breaking of pipeline, normal the carrying out produced of impact.As an important component part of pipework, compensator normally plays an important role in operation for a long time at guarantee pipeline.
Existing compensator mostly is metal corrugation compensator, FlexbleJoint is the angular displacement utilizing the dilatation of bellows to carry out extraction duct to cause because expanding with heat and contract with cold, the FlexbleJoint of this structure, the dilatation amount of bellows is limited on the one hand, therefore compensate limited to expanding with heat and contract with cold of pipeline, on the other hand bellows also easily causes the damage of bellows in ceaselessly telescopic process.
Summary of the invention
The invention is intended to provide a kind of and the spherical compensator for pipe thermal compensation of compensator compensates scope can be set according to pipeline requirement of expanding with heat and contract with cold.
The spherical compensator for pipe thermal compensation in this programme, comprise housing and spheroid, the first groove housing offering inlet opening and communicate with inlet opening, housing place is connected with pressing plate, pressing plate offers conical through-hole, hold-down plate surface is the small end of conical through-hole to the side of housing, spheroid comprises bulb section and construction section, bulb section is passed conical through-hole and is stretched in the first groove, spheroid can around the to-and-fro motion in conical through-hole of the center of bulb section, bulb section is provided with the second groove, construction section is provided with liquid outlet opening, second groove both sides communicate with the first groove and inlet opening respectively, inlet opening, first groove, second groove and liquid outlet opening form the circulation path of liquid in pipeline.
The principle of this programme is: when carrying out the conveying of liquid in pipeline, liquid enters from inlet opening, flow through the first groove and the second groove and flow out from liquid outlet opening, when expanding with heat and contract with cold appears in the liquid carried in pipeline, be arranged on the spherical compensator on pipeline by the angular displacement of extraction duct, now the spheroid of spherical compensator will to-and-fro motion in conical through-hole centered by bulb section, thus reduces the internal stress that pipeline produces because expanding with heat and contract with cold.
The effect of this programme is: by arranging spherical compensator in the duct, pipeline to be heated and the converts displacement produced is the to-and-fro motion of spheroid around bulb section center, by changing the size of the conical through-hole on pressing plate, spheroid can be changed around the reciprocating scope in bulb section center, namely the compensation range of spherical compensator is changed, therefore the compensation range of the spherical compensator of this programme is large, fully can meet the compensation demand that pipeline expands with heat and contract with cold.
Further, bulb section and the first groove fit place are also respectively equipped with the first seal ring and the second seal ring, first seal ring is mainly used in preventing internal liquid from leaking from the cooperation place of bulb section and the first groove, second seal ring is mainly used in preventing foreign matter from entering the inside of spherical compensator from the cooperation place of bulb section and the first groove, has influence on the normal work of spherical compensator.
Further, housing is provided with the first outer stopper coordinated with external pipe, and spheroid is provided with the second outer stopper coordinated with external pipe, the mode accurate positioning that seam coordinates, and easy for installation.
Further, housing is connected by six the second bolts that circumference is uniform with pressing plate, the Placement convenient disassembly of bolt, and switching performance is reliable.
