Specific embodiment
Below in conjunction with attached drawing, specific embodiment of the present utility model is illustrated.
Fig. 1 illustrates pressure balanced compensator comprising the first fixing pipe 1 of coaxial arrangement, the second fixing pipe 2 and one
Bellows 3, the opposite one end of two fixing pipes are all set in the inside of the bellows 3.The both ends of the bellows 3 point
Not Ju You a mounting flange, also respectively there is on the other end of two fixing pipes a mounting flange, the side from attached drawing 1
Always it sees, is followed successively by the first mounting flange 11, the second mounting flange 31, third mounting flange 32 and the 4th fixation from left to right
Orchid 21.There is ring type seal 33, the ring type seal 33 on first fixing pipe 1 and the contact surface of the bellows 3
It is embedded in the groove on the radially inner side face of second mounting flange 31.First fixing pipe 1 and described second is fixed
Pipe 2 can prolong the opposite sliding of axial progress, because of the effect of the ring type seal 33, institute in 3 inner radial of bellows
It states the first fixing pipe 1 and sliding axially for second fixing pipe 2 not will cause being connected to outside for channel interior.
Wherein first mounting flange 11 is fixedly connected with the third mounting flange 32 by axial connecting rod 5, and
Second mounting flange 31 is fixedly connected with the 4th mounting flange 21 also by the connecting rod 5.The bellows 3 as a result,
Both ends are fixedly connected with two fixing pipes respectively, when first mounting flange 11 is as first fixing pipe 1 is along axis
To when being moved, the third mounting flange 32 is also axially moved therewith, and the bellows 3 also prolongs axis therewith
To being compressed or stretched.Identical situation also occurs in the situation that the 4th mounting flange 21 moves.Regardless of hair
Raw compression stretches, and remains sealing on the contact surface of the bellows 3 and two fixing pipes.
Fig. 2 illustrates the pressure balanced compensator of the present embodiment from another angle, first mounting flange 11 with
On the third mounting flange 32, it is respectively provided with the lug 13 of three location matches, it is convex on first mounting flange 11
Lug on ear and the third mounting flange 32 corresponds, and two compositions are a pair of, and the both ends of the connecting rod 5, which are each passed through, to be set
The through-hole 12 on every a pair of of lug 13 is set, and is fixed with the lug at both ends 13.It is every a pair of lug 13 in circumference side
Upward position is identical, therefore each connecting rod 5 passed through after through-hole 12 is along the axis for being parallel to the pressure balanced compensator
Extend to direction, i.e., and along the direction of motion of first fixing pipe 1 and second fixing pipe 2 extends.Same structure
Lug 13 and connecting rod 5 be also set on second mounting flange 31 and the 4th mounting flange 21.Above-mentioned six groups of lugs-
Link mechanism is equally spacedly arranged in a circumferential direction.
It diameter lesser end and the middle part that is relatively large in diameter that the connecting rod 5, which has, and end is equipped with screw thread, between form one
A stepped structure is arranged with cone in the two sides of the through-hole 12 wherein two each ends are each passed through the through-hole 12 respectively
Shape seat 51 and spheric washer 52, the side of lug 13 clamp a pair of of conical seat 51 and spheric washer together with the stepped structure
52, the other side clamps another pair conical seat 51 and spheric washer 52 together with the nut being screwed on the end.
Fig. 3 illustrates GIS or high voltage bus pipe with above-mentioned pressure balanced compensator, wherein in the pressure balance
The two sides of compensator pass through first mounting flange 11 and the 4th mounting flange 21 and piping connection respectively.When pipeline because of temperature
When the variation of axial dimension occurs for degree variation, it is fixed that the change in size will lead to first mounting flange 11 and/or second
Flange 21 generates axial movement, thus drives the axial movement of first fixing pipe 1 and/or the second fixing pipe 2, and this axis
It will cause the compression or stretching of the bellows 3 to movement, to eliminate the generation of stress.
Further, since bellows 3 can not only generate axial deformation, can also occur to a certain extent radial curved
Song, so, using the precision controlling of the GIS and/or high voltage bus pipe of above-mentioned pressure balanced compensator during the installation process
It is required that being reduced, because above-mentioned pressure balanced compensator can also eliminate certain radial missing.
