Abstract
The utility model discloses an overlapped composite sleeve barrel compensator, which comprises an inner sleeve (1), an annular plate (2), an outer sleeve pipe (3), a first outer sleeve guide ring (4), a second outer sleeve guide ring (5), a sealing ring (7), a separated sleeve guide ring (8), a separated guide ring (9) and a separated sleeve (10), wherein the inner sleeve (1), the first outer sleeve guide ring (4), the sealing ring (7), the separated sleeve guide ring (8) and the separated sleeve (10) form a main sealing belt of the compensator, the outer sleeve pipe (3), the second outer sleeve guide ring (5), the sealing ring (7) and the separated guide ring (9) form a secondary sealing belt of the compensator, and the main sealing belt and the second sealing belt are in an overlapped form. The overlapped composite sleeve compensator provided by the utility model has the advantages that the structure is simple, the secondary sealing is realized, high temperature resistance and high pressure resistance can be realized, the leakage is avoided, the processing and the manufacture are simple, the efficiency is high, and the mass production can be realized, so the overlapped composite sleeve barrel compensator has wide application prospects.
Description
Technical field
The utility model relates to the pressure piping element, relates in particular to the compound sleeve expansion joint of a kind of stack.
Background technique
Sleeve expansion joint is to be used for compensating the piping displacement that pipeline causes because of the variation of medium temperature, and with respect to FlexbleJoint, sleeve expansion joint is very effective on the problem that solves impact of water hammer; In order to make the heat distribution pipe network safe operation; Leakage problem becomes more important, and sleeve expansion joint commonly used is the sealing of single chamber; Withstand high temperatures, high pressure ability relatively a little less than, seepage takes place easily.When medium was high-temperature steam, single entry Seal cage leakage problem was particularly outstanding, adopted the compound sealing of stack, can improve the reliability of sealing, for solution high temperature, high pressure steam pipe network provide a kind of desirable compensation device.
The model utility content
The purpose of the utility model provide a kind of on original sleeve expansion joint basis the compound sleeve expansion joint of stack of secondary seal.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: the compound sleeve expansion joint of a kind of stack; Comprise interior cover (1), ring flat-plate (2), outer sleeve (3), the first overcoat guide ring (4), the second overcoat guide ring (5), seal ring (7), spacer sleeve guide ring (8), interval guide ring (9) and spacer sleeve (10); Ring flat-plate (2) is arranged between interior cover (1) and the outer sleeve (3); The second overcoat guide ring (5), seal ring (7), interval guide ring (9) are arranged between outer sleeve (3) and the spacer sleeve (10); The first overcoat guide ring (4), spacer sleeve guide ring (8) are arranged between interior cover (1) and the spacer sleeve (10); Interior cover (1), the first overcoat guide ring (4), seal ring (7), spacer sleeve guide ring (8) and spacer sleeve (10) constitute the primary seal band of compensator; Outer sleeve (3), the second overcoat guide ring (5), seal ring (7) and interval guide ring (9) constitute the secondary seal band of compensator, and said primary seal band and secondary seal band are overlapping.
Be provided with die-pressed graphite ring (11) between said first overcoat guide ring (4) and the spacer sleeve guide ring (8).
Be provided with between said second overcoat guide ring (5) and the seal ring (7) and can annotate stuffing box packing (12).
Said outer sleeve (3) is provided with syrup filling tip (6).
The compound sleeve expansion joint of a kind of stack of the utility model, simple in structure, realized secondary seal, high temperature resistant, high pressure, ne-leakage, manufacturing is simple, efficient is high, can realize production in enormous quantities, so it has broad application prospects.
Description of drawings
Fig. 1 is the structural representation of a kind of compound sleeve expansion joint that superposes of the utility model.
Among the figure: 1, interior cover; 2, ring flat-plate; 3, outer sleeve; 4, the first overcoat guide ring; 5, the second overcoat guide ring; 6, syrup filling tip; 7, seal ring; 8, spacer sleeve guide ring; 9, interval guide ring; 10, spacer sleeve; 11, die-pressed graphite ring; 12, can annotate stuffing box packing.
Embodiment
As shown in Figure 1; Compound sleeve expansion joint superposes; Cover 1 in comprising, ring flat-plate 2, outer sleeve 3, the first overcoat guide ring 4, the second overcoat guide ring 5, syrup filling tip 6, seal ring 7, spacer sleeve guide ring 8, guide ring 9, spacer sleeve 10, die-pressed graphite ring 11 and can annotate stuffing box packing 12 at interval, in ring flat-plate 2 is arranged between cover 1 and the outer sleeve 3, the second overcoat guide ring 5, seal ring 7, guide ring 9 is arranged between outer sleeve 3 and the spacer sleeve 10 at interval; In the first overcoat guide ring 4, spacer sleeve guide ring 8 are arranged between cover 1 and the spacer sleeve 10; In cover 1, the first overcoat guide ring 4, seal ring 7, spacer sleeve guide ring 8 and spacer sleeve 10 constitute the primary seal band of compensators, outer sleeve 3, the second overcoat guide ring 5, seal ring 7 and at interval guide ring 9 constitute the secondary seal band of compensators, primary seal band and secondary seal band are overlapping; The secondary seal band is when sealing; The auxiliary primary seal band that strengthens is realized self maintained by pressure medium to Seal cage during work, for the bearing capacity that improves contact surface with prevent surface etching; The outer surface of interior cover 1 and spacer sleeve 10 carries out surface hardening and anti-corrosion treatment; The outside of sleeve pipe adds one deck overcoat and sealing surface more outside, does not produce overvoltage when guaranteeing that air between outermost overcoat and the interior pipe medium temperature in steel pipe raises, and adopts the negative pressure fit during assembling; When seepage takes place when; Can implement filler to the secondary seal band, because the sealing band is to belong to time sealing strip, so filler can carry out when seepage is not too serious under the situation that does not stop the pipeline operation.
