Abstract
The invention discloses a superposed compound sleeve compensator. The compensator comprises an inner sleeve (1), an annular plate (2), an outer sleeve pipe (3), an outer sleeve guide ring (4), an outer sleeve guide ring (5), a sealing ring (7), a spacer sleeve guide ring (8), a spacer sleeve guide ring (9) and a spacer sleeve (10). A main sealing belt of the compensator is composed of the inner sleeve (1), the outer sleeve guide ring (4), the sealing ring (7), the spacer sleeve guide ring (8) and the spacer sleeve (10). A secondary sealing belt of the compensator is composed of the outer sleeve pipe (3), the outer sleeve guide ring (5), the sealing ring (7) and the spacer guide ring (9). The main sealing belt and the secondary sealing belt are manufactured in a superposed way. The superposed compound sleeve compensator is simple in structure, capable of realizing secondary sealing, high-temperature resistant, high-pressure resistant, leakage-free, simple to process and manufacture, high in efficiency and capable of realizing mass production, therefore the compensator has wide application prospects.
Description
Technical field
The present invention relates to the pressure piping element, relate 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.
Summary of the invention
The purpose of this invention is to provide a kind of on original sleeve expansion joint basis the compound sleeve expansion joint of stack of secondary seal.
The present invention 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), overcoat guide ring (4), 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); Overcoat guide ring (5), seal ring (7), interval guide ring (9) are arranged between outer sleeve (3) and the spacer sleeve (10); Overcoat guide ring (4), spacer sleeve guide ring (8) are arranged between interior cover (1) and the spacer sleeve (10); Interior cover (1), 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), 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 overcoat guide ring (4) and the spacer sleeve guide ring (8).
Be provided with between said 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 present invention, 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 present invention.
Among the figure: 1, interior cover; 2, ring flat-plate; 3, outer sleeve; 4, overcoat guide ring; 5, overcoat guide ring; 6, seal ring; 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, overcoat guide ring 4, 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, overcoat guide ring 5, seal ring 7, guide ring 9 is arranged between outer sleeve 3 and the spacer sleeve 10 at interval; Overcoat guide ring 4, spacer sleeve guide ring 8 are arranged between interior cover 1 and the spacer sleeve 10; In cover 1, 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, 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.
