When the pipeline expands with heat and contracts with cold, the outer cylinder and the inner cylinder move relatively, so that the sealing filler is abraded, and the sealing performance is reduced.
Disclosure of Invention
In order to solve the problems, the invention provides a self-sealing sleeve compensator which can automatically compensate the abrasion of a sealing filler and maintain the sealing performance.
The technical scheme of the invention is that the self-sealing sleeve compensator comprises an outer cylinder 10 and an inner cylinder 12 inserted in the outer cylinder, wherein a sealing filler 9 is arranged between the outer cylinder and the inner cylinder, one end of the sealing filler is attached to the end surface of a ring body 11 at the right end of the outer cylinder, the other end of the sealing filler is attached to a pressing sleeve 2, the novel pressure sleeve is characterized in that the inner circle of the pressure sleeve is sleeved on the inner cylinder, the small head of the outer circle of the pressure sleeve is inserted into the outer cylinder, the large head of the outer circle of the pressure sleeve is inserted into the inner wall of the pressure cover 3, a sealing ring is arranged between the large head of the outer circle of the pressure sleeve and the inner wall of the pressure cover, a convex ring extends leftwards from the large head of the outer circle of the pressure sleeve, the convex ring is attached to the side wall of the pressure cover, a connecting pipe 1 extends leftwards from the inner circle of the side wall of the pressure cover, a right flange 6 extends from the right end of the pressure cover, a left flange 7 extends from the left end of the outer cylinder, the right flange.
The self-sealing sleeve compensator is characterized in that a bolt is screwed, the outer cylinder and the gland are close to each other, the sealing filler is clamped by the pressing sleeve and the ring body of the outer cylinder, and because the sealing filler is stressed bidirectionally, the radial force of two ends of the sealing filler to the inner cylinder is basically uniform, thereby avoiding ineffective abrasion of the sealing filler; the medium in the self-sealing sleeve compensator has certain pressure, and the medium pressure acts on the left end face of the pressing sleeve to enable the pressing sleeve to press the sealing filler to compensate the abrasion of the sealing filler.
The invention has the advantages that the abrasion of the sealing filler can be automatically compensated; when the pressure of the medium rises, the pressure of the pressing sleeve on the sealing filler also increases, and the sealing performance of the sleeve compensator is maintained; when the pressure of the medium is reduced, the pressure of the pressing sleeve on the sealing filler is also reduced, and the abrasion of the sealing filler is reduced; the service life of the sleeve compensator can be prolonged.

Detailed Description
Specific embodiments of the present invention will now be described with reference to the accompanying drawings.
A self-sealing sleeve compensator comprises an outer cylinder 10 and an inner cylinder 12 inserted into the outer cylinder, wherein a sealing filler 9 is arranged between the outer cylinder and the inner cylinder, the sealing filler is flexible graphite, one end of the sealing filler is attached to the end face of a ring body 11 at the right end of the outer cylinder, and the other end of the sealing filler is attached to a pressing sleeve 2.
The axial cross-section of pressing the cover is the zigzag, the interior circle cover of pressing the cover is on the inner tube, the little head of pressing the cover excircle is inserted in the urceolus, the major part of pressing the cover excircle is inserted in the inner wall of gland 3, be equipped with sealing washer 4 between the major part of pressing the cover excircle and the inner wall of gland, the major part of pressing the cover excircle extends a bulge loop left, the bulge loop pastes with the lateral wall of gland, the interior circle department of gland lateral wall extends left has takeover 1, the right-hand member of gland extends has right flange 6, the left end of urceolus extends has left flange 7, be connected by a plurality of bolts 8 between right flange and the left flange, the bolt both ends have the nut soon.
The nut is screwed, the outer cylinder and the gland are close to each other, the sealing filler is clamped by the pressing sleeve and the ring body of the outer cylinder, the sealing filler is radially expanded to be tightly attached to the inner cylinder and the outer cylinder, and the outer cylinder and the inner cylinder are sealed; the sealing ring can prevent the medium from leaking along the gland.
Because the sealing filler is stressed bidirectionally, the radial force of the two ends of the sealing filler to the inner cylinder is basically uniform, and the ineffective abrasion of the sealing filler is avoided.
When the self-sealing sleeve compensator is installed, the self-sealing sleeve compensator is connected in series in a pipeline, namely, the connecting pipe is in sealing connection with one section of the pressure pipeline, the inner pipe is in sealing connection with the other section of the pressure pipeline, a medium in the pipeline has certain pressure, and the medium pressure acts on the left end face of the pressing sleeve to enable the pressing sleeve to press the sealing filler to compensate the abrasion of the sealing filler.
In order to ensure that medium pressure can fully act on the left end face of the pressing sleeve, the inner diameter of the convex ring on the pressing sleeve is larger than the inner circle of the pressing sleeve, and the ratio of the inner diameter of the convex ring on the pressing sleeve to the diameter of the inner circle of the pressing sleeve is 4: 3.
in order to better compensate the abrasion of the sealing packing, the bolt is sleeved with a spring 5, the spring is positioned outside the right flange and/or the left flange, and the spring is pressed by the nut.
