The invention has the advantages that when the sealing filler is worn, the sliding ring is pushed to move rightwards by the action force of the spring, and the sealing filler can be always in a pressed state because the sliding ring is not blocked by the hemispherical surface, thereby keeping the sealing performance and prolonging the service life.
Description
Technical Field
The invention relates to a spherical compensator.
Background
The spherical compensator is installed in the pipeline and is used for compensating the axial displacement or angular displacement of the heat distribution pipeline so as to protect the pipeline. The spherical compensator generally comprises an outer cylinder and an inner cylinder, wherein the hemispherical surface of the inner cylinder is positioned in the outer cylinder, a sealing filler is arranged between the hemispherical surface of the inner cylinder and the outer cylinder, the sealing filler is compressed by a gland, and when the pipeline generates expansion with heat and contraction with cold, the inner cylinder and the outer cylinder can rotate relatively to absorb the displacement of the pipeline in all directions. The relative movement between the inner cylinder and the outer cylinder can lead the sealing filler to be worn, thus leading the sealing performance to be reduced. In order to compensate the abrasion of the sealing filler, the method adopted usually is to compress the sealing filler again, because the inner diameter of the gland is smaller than the diameter of the spherical surface of the inner cylinder, after the sealing filler is compressed for many times, the acting force of the gland can be on the spherical surface of the inner cylinder, the sealing filler can not be compressed, so that the abrasion can block the gland to solve the problem that the sealing performance of the spherical compensator is reduced.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the long-service-life spherical compensator which can effectively compensate the abrasion of the sealing filler, maintain the sealing performance and prolong the service life.
The invention has the technical scheme that the long-service-life spherical compensator comprises an outer cylinder 2 and an inner cylinder 8, wherein the outer surface of the inner cylinder is a hemispherical surface, the hemispherical surface of the inner cylinder is positioned in the outer cylinder, a sealing filler 6 is arranged between the hemispherical surface of the inner cylinder and the outer cylinder, the inner diameter of the left end of the sealing filler is equal to the outer diameter of the hemispherical surface, the inner diameter of the right end of the sealing filler is smaller than the outer diameter of the hemispherical surface, a baffle ring 3 is arranged on the left side of the sealing filler and fixedly connected to the inner wall of the outer cylinder, the inner surface of the baffle ring is attached to the hemispherical surface, a gland 7 is arranged on the right side of the sealing filler, a pressing sleeve is connected with the outer cylinder through a bolt, and the; the sealing packing structure is characterized in that a sliding ring 5 is further arranged between the retaining ring and the sealing packing, the outer diameter of the sliding ring is matched with the inner diameter of the outer cylinder, the inner diameter of the sliding ring is slightly larger than the outer diameter of the hemispherical surface, a plurality of axial reducing holes are symmetrically arranged on the retaining ring, springs 4 are inserted into the reducing holes, and the springs are in contact with the left end face of the sliding ring.
Compared with the prior art, the invention has the advantages that when the sealing filler is worn, the sliding ring is pushed to move rightwards by the action force of the spring, and the sliding ring can be always in a compressed state because the sliding ring is not blocked by the hemispherical surface, thereby keeping the sealing performance and prolonging the service life.

Detailed Description
Specific embodiments of the present invention will now be described with reference to the accompanying drawings.
A long-life spherical compensator comprises an outer cylinder 2, wherein a reducing part of the outer cylinder is hermetically welded with an inlet pipe 1, the outer surface of an inner cylinder 8 is a hemispherical surface, most of the hemispherical surface is positioned in the outer cylinder, a small part of the hemispherical surface is exposed out of the outer cylinder, and the exposed end of the hemispherical surface is hermetically connected with an outlet pipe 9; the sealing filler 6 is arranged between the hemispherical surface of the inner barrel and the outer barrel, the inner diameter of the left end of the sealing filler is equal to the outer diameter of the hemispherical surface, the inner diameter of the right end of the sealing filler is smaller than the outer diameter of the hemispherical surface, the left side of the sealing filler is provided with the baffle ring 3, the baffle ring is welded on the inner wall of the outer barrel, the inner surface of the baffle ring is attached to the hemispherical surface, the right side of the sealing filler is provided with the gland 7, the pressure sleeve is connected with the outer barrel through a bolt, and the pressure sleeve is compressed to enable the sealing filler to be in.
And a sliding ring 5 is further arranged between the retaining ring and the sealing filler, the outer diameter of the sliding ring is matched with the inner diameter of the outer cylinder, the inner diameter of the sliding ring is slightly larger than the outer diameter of the hemispherical surface, a plurality of axial variable-diameter holes are symmetrically arranged on the retaining ring, a spring 4 is inserted into each variable-diameter hole, and the spring is in contact with the left end surface of the sliding ring.
As an improvement, the left end face of the slip ring is provided with a shaft body 10, the shaft body penetrates through the spring and extends out of the left end face of the baffle ring, and the left end of the shaft body is fixedly connected with a ring plate 12. The ring plate receives the pressure of medium in the pipeline, promotes the sliding ring and compresses tightly the sealing filler, realizes self sealedly, can reduce the intensity of spring simultaneously, avoids the spring fatigue.
As a further improvement, a sleeve body 11 extends rightwards from the inner circle of the annular plate, the sleeve body is close to the right end of the inner cylinder, and the inner diameter of the sleeve body is equal to that of the inlet pipe and the outlet pipe. The sleeve can prevent the medium from generating turbulence in the inner cylinder and reduce the consumption of medium transmission power.
