Description
Technical field
This utility model relates to compensator, is specially a kind of ball joint compensator for pipe thermal compensation.
Background technology
Compensator is also called compensator or telescopic joint, expansion joint, is mainly used in compensating pipeline by variations in temperature and expanding with heat and contract with cold of producing.If during variations in temperature pipeline can not completely freely expansion or shrinkage, pipeline will produce thermal stress.Must take into this stress in pipe design, otherwise it may result in breaking of pipeline, normal the carrying out produced of impact.As an important component part of pipeline engineering, compensator ensure pipeline long-term properly functioning in play an important role.
Existing compensator mostly is metal corrugation compensator, FlexbleJoint is that the dilatation utilizing corrugated tube carrys out the angular displacement that extraction duct causes because expanding with heat and contract with cold, the FlexbleJoint of this structure, the dilatation amount of corrugated tube is limited on the one hand, therefore the compensation of expanding with heat and contract with cold of pipeline is limited, corrugated tube also easily causes the damage of corrugated tube in ceaselessly telescopic process on the other hand.
Utility model content
This utility model is intended to provide a kind of can arrange the ball joint compensator for pipe thermal compensation of compensator compensation range according to pipeline requirement of expanding with heat and contract with cold.
The ball joint compensator for pipe thermal compensation in this programme, including housing and spheroid, housing offers inlet opening and the first groove communicated with inlet opening, housing place is connected to pressing plate, pressing plate offers conical through-hole, pressing plate is towards the small end that side is conical through-hole of housing, spheroid includes bulb section and construction section, bulb section is through conical through-hole and stretches in the first groove, spheroid can move back and forth in conical through-hole around the center of bulb section, bulb section is provided with the second groove, construction section is provided with liquid outlet, second groove both sides communicate with the first groove and inlet opening respectively, inlet opening, first groove, second groove and liquid outlet 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, when in pipeline, expanding with heat and contract with cold occurs in the liquid of conveying, it is arranged on the ball joint compensator on pipeline by the angular displacement of extraction duct, now the spheroid of ball joint compensator will move back and forth centered by bulb section in conical through-hole, thus reducing the internal stress that pipeline produces because expanding with heat and contract with cold.
The effect of this programme is: by arranging ball joint compensator in the duct, the displacement being heated by pipeline and produce is converted into the spheroid reciprocating motion 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 ball joint compensator is changed, therefore the compensation range of the ball joint compensator of this programme is big, can fully meet the compensation demand that pipeline expands with heat and contract with cold.
Further, bulb section and the first groove fit place further respectively have the first sealing ring and the second sealing ring, first sealing ring is mainly used in preventing internal liquid from coordinating leakage from bulb section and the first groove, second sealing ring is mainly used in the inside coordinating entrance ball joint compensator preventing foreign matter from bulb section with the first groove, has influence on the normal operation of ball joint compensator.
Further, housing is provided with the first male half coupling coordinated with external pipe, and spheroid is provided with the second male half coupling coordinated with external pipe, the mode accurate positioning that seam coordinates, and easy for installation.
Further, housing is attached by six the second bolts that circumference is uniform with pressing plate, the connected mode convenient disassembly of bolt, and switching performance is reliable.
