Description
Technical field
The utility model is related to pipe safety devices, particularly relate to a kind of corrugated expansion joint.
Background technology
FlexbleJoint is traditionally also expansion joint or telescopic joint, is used primarily in various pipelines, it can compensate for pipe
The thermal walking and mechanically deform in road, absorb various mechanical oscillation, and playing reduces pipe deforming stress and raising pipeline service life
Effect.FlexbleJoint can be to axial direction, horizontal and angular displacement absorption.Existing FlexbleJoint often can only be real
Existing single directional compensation, such as axialmode compensator can only realize displacement in the axial direction, and single entry hinge type FlexbleJoint is only
The angular displacement in a plane can be absorbed.
Utility model content
The utility model discloses a kind of corrugated expansion joints, can not only realize axial displacement, but also can realize angular displacement.
The utility model is achieved through the following technical solutions：
A kind of corrugated expansion joint is inserted including the first pull rod, runner, the second pull rod, nut, bellows, pipe nipple, first
Hole, the second jack, bolt, the bellows both ends connect the pipe nipple, and first pull rod and the second pull rod use institute respectively
It states nut to be fixed on the pipe nipple, the runner is connected between first pull rod and the second pull rod and is inserted into it respectively
In, the runner is equipped with first jack, and second jack is respectively equipped in the middle part of first pull rod and the second pull rod, inserts
Enter the runner part and be respectively equipped with first jack, and overlapped with the jack on the runner, when the first pull rod and second
When pull rod is in same horizontal line, it can be inserted into the bolt and be fixed.
Preferably, the bellows is using austenitic stainless steel (such as 304,316,316L).
Preferably, the bolt is set there are three inserted link, is inserted into first jack and the second jack respectively.
Compared with prior art, the beneficial effects of the utility model are：The corrugated expansion joint of the utility model not only may be used
To realize axial displacement, angular displacement can also be realized.

Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of corrugated expansion joint, including the first pull rod 1, runner 2, the second pull rod 3, nut 4, bellows 5, pipe nipple 6,
First jack 7, the second jack 8, bolt 9,5 both ends of bellows connect the pipe nipple 6, first pull rod 1 and second
Pull rod 3 is fixed on the nut 4 on the pipe nipple 6 respectively, is connected between 1 and second pull rod 3 of the first pull rod described
Runner 2 is simultaneously inserted respectively, and the runner 2 is equipped with first jack 7, part in 1 and second pull rod 3 of the first pull rod
Not She You second jack 8, be inserted into 2 part of runner and be respectively equipped with first jack 7, and on the runner 2
Jack overlaps, and when the first pull rod 1 and the second pull rod 3 be in same horizontal line, the pluggable bolt 9 is fixed.
The bellows 4 is using austenitic stainless steel (such as 304,316,316L).
The bolt 9 is set there are three inserted link, is inserted into 7 and second jack 8 of the first jack respectively.
The bolt 9 is inserted into 7 and second jack 8 of the first jack so that 1 and second pull rod 3 of the first pull rod
It fixes in the horizontal direction, corrugated expansion joint can only realize axial displacement at this time, realize compensation in the axial direction；As shown in figure 4,
When removing the bolt 9,1 and second pull rod 3 of the first pull rod is free to slide, and corrugated expansion joint can only absorb one at this time
Angular displacement in plane can simultaneously bear bellows pressure thrust.
The above only expresses the embodiment of the utility model, and description is more specific and in detail, but can not be because
This and be interpreted as the limitation to the utility model patent scope, within the spirit and principle of the utility model, made appoint
What modification, equivalent substitution, improvement etc., should be included within the scope of protection of this utility model, the guarantor of the utility model patent
Shield scope should be determined by the appended claims.
