Abstract
The invention discloses a sleeve compensator used for compensating expansion of a pipeline. The sleeve compensator comprises an inner pipe (1), an outer pipe (2) and a sleeve body (3). A positioning plate (7) is welded to the middle of the inner pipe. One end of the sleeve body is in seal connection with the positioning plate. The sleeve compensator is characterized in that the other end of the sleeve body is in seal connection with a casing pipe (6); the outer pipe penetrates through the casing pipe and extends into the sleeve body; a silica rubber pipe (8) is in seal connection between the end, extending into the sleeve body, of the outer pipe and the casing pipe; a gap is reserved between the silica rubber pipe and the sleeve body. According to the sleeve compensator, the outer pipe is a movable component and does not in seal contact with the casing pipe, and the silica rubber pipe can prevent fluid in the sleeve compensator from flowing out along the space between the outer pipe and the casing pipe. Compared with the prior art, the silica rubber pipe can only stretch out and draw back without being abraded when the outer pipe moves, so that the service life of the sleeve compensator is ensured; due to the fact that no friction exists between the silica rubber pipe and the outer pipe, the outer pipe can move flexibly, and the compensation effect is improved.
Description
Technical field
The present invention relates to a kind of for compensating the sleeve expansion joint that hot-water line diatom expands, it is serially connected on hot water pipeline, its structure comprises the inner and outer tubes allowing fluid pass through, and when heat distribution pipeline generation line expands, inner and outer tubes realize the compensation of expanding to line by relative movement.
Background technique
The structure of existing sleeve expansion joint generally comprises inner and outer tubes, interior pipe is inserted in outer tube, is provided with stuffing box packing between interior pipe and outer tube, and the end of inner and outer tubes is connected on heat distribution pipeline, when hot water pipeline generation line expands, inner and outer tubes realize the compensation of expanding to line by relative movement; Its deficiency is, the relative movement of interior pipe and outer tube can make filler generation wearing and tearing cause sealability to decline; When pipeline generation line expands in addition, its direction of displacement and the relative movement direction of sleeve expansion joint inner and outer tubes are difficult to ensure consistent, make stuffing box packing friction amesiality, make the wearing and tearing of filler aggravation shorten the working life of sleeve expansion joint.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of sleeve expansion joint, and in it, pipe can not make seal element wear and tear with the relative movement of outer tube, improves the working life of sleeve expansion joint.
Technological scheme of the present invention is, sleeve expansion joint comprises interior pipe 1, outer tube 2, cylindrical shell 3, the neutral position of interior pipe is welded with positioning disk 7, on one end of cylindrical shell and interior pipe, positioning disk is tightly connected, it is characterized in that the other end of cylindrical shell is sealedly connected with sleeve pipe 6, outer tube is through putting in cylindrical shell from sleeve pipe, and outer tube puts between the end of cylindrical shell and sleeve pipe and is sealedly connected with silicone rubber tube 8, leaves gap between silicone rubber tube and cylindrical shell.
Being movable part at this sleeve expansion joint middle external tube, is not that sealing contacts between it with sleeve pipe, silicone rubber tube can fluid in barrier sleeve compensator along the outflow between outer tube and sleeve pipe.Compared with prior art, silicone rubber tube can only be made when outer tube moves to occur flexible and wearing and tearing can not be caused to silicone rubber tube, ensure that the working life of sleeve compensator; Because zerofriction force between silicone rubber tube and outer tube occurs, make the movement of outer tube flexible, improve compensation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Now contrast accompanying drawing and specific embodiments of the invention are described.
First embodiment: this sleeve expansion joint comprises interior pipe 1, outer tube 2, cylindrical shell 3; Be welded with the first flange plate 4 in one end of cylindrical shell, interior pipe be welded with positioning disk 7, positioning disk is connected on the first flange plate by bolt 11, is provided with seal washer 10 between positioning disk and the first flange plate; The other end of cylindrical shell is welded with the second flange plate 5, and the flange on sleeve pipe 6 is bolted on the second flange plate, is provided with seal washer between the flange of sleeve pipe and the second flange plate; Outer tube from sleeve pipe through putting in cylindrical shell, outer tube can slide in sleeve pipe, the cylindrical that outer tube puts in the end of cylindrical shell is provided with groove, the cylindrical of cannula tip is also provided with groove, outer tube puts between the end of cylindrical shell and cannula tip and is connected with silicone rubber tube 8, and silicone rubber tube is tied tight in the groove of outer tube and sleeve pipe by clip 9; Gap is left between silicone rubber tube and cylindrical shell.
The length (i.e. the partial-length of silicone rubber tube between outer tube groove and casing recess) of the scalable part of silicone rubber tube should be greater than the extreme length of compensated pipeline when line occurring and expanding, select the length of the scalable part of silicone rubber tube be compensation pipeline when line occurring and expanding 3 to 5 times of extreme length; The tension force that silicone rubber tube bears can be reduced like this.
For reducing the resistance of fluid by sleeve expansion joint, one end of interior pipe is stretched within the outer tube.
Operationally, silicone rubber tube overlays on outer tube this sleeve expansion joint by pipe fluid pressure, be applied to pressure on silicone rubber tube absorb by outer tube, therefore this sleeve expansion joint can use under higher working pressure environment.Silicone rubber material has high temperature resistant and cold tolerance, and its Environmental Conditions temperature is-70 DEG C to 330 DEG C.When the line compensating pipeline expands, silicone rubber tube can not produce wearing and tearing, and the operating life of silicone rubber tube depends on its ageing-resistant life-span, and ducted fluid makes silicone rubber tube not easily aging from the impact of light, oxygen, and therefore its operating life can reach more than 10 years.
Second embodiment: be one end that positioning disk on interior pipe is directly welded on cylindrical shell with the difference of the first embodiment; Described sleeve pipe is directly welded on the other end of cylindrical shell; Flange plate and seal washer can be saved like this.Described silicone rubber tube can be glued on outer tube and sleeve pipe with cement.
Claims (3)
1. a sleeve expansion joint comprises interior pipe (1), outer tube (2), cylindrical shell (3), the neutral position of interior pipe is welded with positioning disk (7), positioning disk on one end of cylindrical shell and interior pipe is tightly connected, it is characterized in that the other end of cylindrical shell is sealedly connected with sleeve pipe (6), outer tube from sleeve pipe through putting in cylindrical shell, outer tube puts between the end of cylindrical shell and sleeve pipe and is sealedly connected with silicone rubber tube (8), leaves gap between silicone rubber tube and cylindrical shell.
2. sleeve expansion joint according to claim 1, is characterized in that the length of the scalable part of silicone rubber tube is for compensated pipeline when line occurring and expanding 3 to 5 times of extreme length.
