Abstract
The utility model discloses an anti-leakage bushing-type pipe compensator, which comprises an inner bushing (1) and an outer bushing (2). The inner bushing (1) and the outer bushing (2) are sealedly connected through a rubber expansion joint; on the expansion end of the inner bushing (1), a labyrinth sealing section (4) is provided; the expansion end of the inner bushing (1) is placed in the expansion end of the outer bushing (2). Comparing with the prior bushing-type pipe compensator, the utility model is of good sealing performance, will not leak, is resistant to wear, of long service life, and good safety property.
Description
Technical field:
The utility model relates to a kind of flexible pipeline compensator of pipeline axial that is used to eliminate, and particularly is applicable to the leak jacket cartridge type pipeline compensator of heating pipe system.
Background technique:
In the heating pipe system, change more to some extent during owing to pipeline internal medium temperature and ambient temperature and installation, therefore cause the bigger change of pipeline at axial direction, make pipeline produce thermal stress; When thermal stress surpasses the allowable stress of tubing, will make pipeline produce distortion or damage, for this reason need be on pipeline the pipe laying compensator, eliminate the flexible harm that brings of pipeline.Shortcomings such as the telescopic pipeline compensator that uses adopts fillers such as asbestos, graphite that inner and outer sleeves is sealed mostly at present, has poor sealing performance, leaks easily, and easy to wear, working life is short.
Summary of the invention:
The purpose of this utility model is: provide a kind of volume little, do not leak, the leak jacket cartridge type pipeline compensator of long service life to overcome the deficiencies in the prior art, is avoided pipe-line system distortion or damage.
The utility model is to constitute like this: it comprises inner sleeve (1), outer sleeve (2), is tightly connected by rubber slip joint (3) between inner sleeve (1), the outer sleeve (2); The flexible end of inner sleeve (1) is provided with labyrinth sealing section (4), and the flexible end of inner sleeve (1) places in the flexible end of outer sleeve (2), and seals by the flexible end of labyrinth sealing section (4) and rubber seal (5) and outer sleeve (2).
Inner sleeve (1) is provided with safety check (6), and the flap (7) of safety check (6) places inner sleeve (1), and the anti-fluctuation spring (8) of safety check (6) places in the Seal cage between rubber slip joint (3) and the inner sleeve (1).
Compared with prior art, the utility model is by rubber slip joint be tightly connected inner sleeve and outer sleeve and adopt form that the labyrinth sealing section combines with rubber seal that the flexible end of inner and outer sleeves is sealed, and good seal performance is not revealed, wear-resistant, long service life.In addition, the utility model also is provided with safety check on inner sleeve, to guarantee its Safety performance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Embodiment of the present utility model: as shown in Figure 1, it comprises inner sleeve 1, outer sleeve 2, and the medium of carrying in order to prevent is revealed, and is tightly connected by rubber slip joint 3 between inner sleeve 1, the outer sleeve 2; The two ends of rubber slip joint 3 are fixed on inner sleeve 1, the outer sleeve 2 by flange 9, clamp flange ring 10 and clamping bolt 11 respectively.In order to guarantee sealing effect, the flexible end of inner sleeve 1 is provided with labyrinth sealing section 4, the flexible end of inner sleeve 1 inserts in the flexible end of outer sleeve 2, and the flexible end of the form that combines by labyrinth sealing section 4 and rubber seal 5 and outer sleeve 2 seals.
In order to make rubber slip joint 3 be no more than design pressure when 2 compressions of inner sleeve 1 and outer sleeve, inner sleeve 1 is provided with a safety check 6, the flap 7 of safety check 6 places inner sleeve 1, and be in the safety check flap casing 13, between flap 7 and the inner sleeve 1 rubber seal 12 is housed, the anti-fluctuation spring 8 of safety check 6 places the Seal cage between rubber slip joint 3 and the inner sleeve 1
In.Safety check 6 cuts out during proper functioning; When the pressure medium of revealing in the rubber slip joint 3 when inner sleeve 1 and outer sleeve 2 are compressed to above design pressure, safety check 6 is opened automatically, the medium that gathers is pushed back in the runner of inner sleeve 1.
