Abstract
The invention discloses a three-dimensional sleeve compensator used for compensating expansion of a heat distribution pipeline. The three-dimensional sleeve compensator comprises an inlet pipe (8) and an outlet pipe (7). The three-dimensional sleeve compensator is characterized in that a corrugated pipe (1) is arranged on the outlet pipe in a sleeving mode; a first baffle (2) and a second baffle (3) are welded to the two ends of the corrugated pipe respectively; the first baffle is connected with one end of the outlet pipe, and the second baffle is arranged on the outlet pipe in a sleeving mode; the inlet pipe is provided with a third baffle (5); the two ends of an outer pipe (6) are welded to the second baffle and the third baffle respectively; the outlet pipe can move in the outer pipe. Compared with the prior art, sealing of the three-dimensional sleeve compensator is achieved through the corrugated pipe, and the defect of abrasion of sealing fillers does not exist; due to the flexible characteristic of the corrugated pipe, the outlet pipe can achieve axial displacement, transverse displacement or angular displacement in a cavity, and the damage to the compensator due to blind plate force produced by the heat distribution pipeline is avoided; meanwhile, the outlet pipe can move flexibly in the cavity, and the compensation effect is ensured.
Description
Technical field
The present invention relates to a kind of sleeve expansion joint, it compensates for expanding to the line of heat distribution pipeline.
Background technique
Existing sleeve expansion joint generally comprises urceolus, inner core; inner core is inserted in urceolus; at the binding site of inner core and urceolus, stuffing box packing is housed; one end of inner core and one end of urceolus are serially connected in heat distribution pipeline; when the generation of heat distribution pipeline temperature influence is expanded with heat and contract with cold; the urceolus of sleeve expansion joint and inner core produce and mobile to compensate the length change of heat distribution pipeline, reach to obtain the object of protection heat distribution pipeline safe operation.The deficiency that this kind of sleeve expansion joint exists is, stuffing box packing can be made to produce to wear and tear the sealability of compensator is declined when urceolus and inner core produce movement; In addition it is consistent with the axial direction of urceolus, inner core that the thrust direction produced when thermal pipe diatom expands is difficult to guarantee, can affect compensation effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of three-dimension type sleeve expansion joint, and this compensator can also compensate a certain amount of lateral displacement or angular displacement except compensating axial displacement.
Technological scheme of the present invention is, three-dimension type sleeve expansion joint comprises inlet tube 8, outer pipe 7, and it is characterized in that on outer pipe, cover has bellows 1, the two ends of bellows weld the first baffle plate 2 and second baffle 3 respectively, first baffle plate 2 is connected to one end of outer pipe, and second baffle is enclosed within outer pipe; Inlet tube is provided with third gear plate 5, and the two ends of outer tube 6 are welded on second baffle and third gear plate respectively; Outer pipe can move in outer tube.
The feature of three-dimension type sleeve expansion joint is inlet tube, third gear plate, outer tube and second baffle form a cavity, and owing to leaving gap between second baffle and outer pipe, outer pipe can do axial displacement, lateral displacement or angular displacement in cavity; The sealing that bellows ensure that cavity is welded with between first baffle plate and second baffle.Compared with prior art the sealing of three-dimension type sleeve expansion joint is the weakness that there are not stuffing box packing wearing and tearing realized by bellows; Due to the flexible feature of bellows, outer pipe can do axial displacement, lateral displacement or angular displacement in cavity, avoids the blind power of pulling that heat distribution pipeline produces to the destruction of compensator, make simultaneously outer pipe can displacement in cavity flexible, ensure compensation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Accompanying drawing mark represents respectively: 1-bellows, 2-first baffle plate, 3-second baffle, 4-reducer pipe, 5-third gear plate, 6-outer tube, 7-outer pipe, 8-inlet tube, 9-block.
Embodiment
As shown in Figure 1, three-dimension type sleeve expansion joint comprises the inlet tube 8 be connected in heat distribution pipeline, outer pipe 7, on outer pipe, cover has bellows 1, the wave number of bellows can be determined by nose balance displacement amount, one end that the first baffle plate 2 and second baffle 3, first baffle plate 2 are connected to outer pipe is welded at the two ends of bellows respectively, and second baffle is enclosed within outer pipe, the external diameter of the first baffle plate is less than the external diameter of second baffle, and the internal diameter of second baffle is slightly larger than the external diameter of outer pipe; Inlet tube is provided with third gear plate 5, and the external diameter of third gear plate is equal with the external diameter of second baffle; The two ends of outer tube 6 are welded on second baffle and third gear plate respectively, make inlet tube, third gear plate, outer tube and second baffle form a cavity, bellows is connected to the first baffle plate from second baffle and makes to be sealed in described cavity by the fluid of compensator.
For reducing fluid by the resistance of compensator, inlet tube 8 is provided with reducer pipe 4, and the end of reducer pipe reaches in outer pipe.
Outer tube is provided with blocking 9, when needed for getting rid of the hydrops in outer tube.
Claims (2)
