Description
Technical field
The present invention relates to Bellows Technology field more particularly to a kind of bellows expansion joints.
Background technique
Existing bellows usually has certain nose balance ability.And in the use of reality when pipeline and pipeline into
When row docking, in addition to there is deviation in axial position, while also there is radial dislocation.Existing bellows expansion joint is only
The compensation for meeting axial offset, without having radial compensation.Therefore need to provide a kind of technical solution to solve such skill
Art problem.
Summary of the invention
The present invention provides a kind of bellows expansion joints, and design and develop the purpose of the present apparatus: the present apparatus had both had certain
Nose balance ability, while but also with certain radial compensation ability.
Technical solution: a kind of bellows expansion joint, the bellows expansion joint include the first tube coupling 1, the second tube coupling 2, the
One end of three tube couplings 3, the first bellows 4, the second bellows 5, one end of first tube coupling 1 and first bellows 4 connects
It connects, the other end of first bellows 4 is connect with one end of second tube coupling 2, the other end of second tube coupling 2 and institute
One end connection of the second bellows 5 is stated, the other end of second bellows 5 is connect with one end of the third tube coupling 3, described
Bellows expansion joint further includes first connecting rod 6, the second connecting rod 7, and the first connecting rod 6, the both ends of the second connecting rod 7 are equal
Equipped with screw thread, connected between first tube coupling 1 and second tube coupling 2 by first connecting rod 6,2 He of the second tube coupling
It is connected between the third tube coupling 3 by the second connecting rod 7.
Beneficial effects of the present invention are as follows: the application is provided with the first bellows 4, the second bellows 5 is able to satisfy axial position
The compensation of shifting unclamps the nut of 8 two sides of engaging lug, this bellows expansion joint when needing to carry out radial compensation
Diametric compensation is completed, after completing good docking, tightens nut.The present apparatus is provided with the first bellows 4, the second bellows
5 can bear certain radial compensation ability, and the amplitude that can be carried out dislocation after the first bellows 4,5 spreading of the second bellows increases
?.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of bellows expansion joint of the present invention.
Specific embodiment
Joint the drawings and specific embodiments make detailed description to the present invention below.
In Fig. 1: the first tube coupling 1, the second tube coupling 2, third tube coupling 3, the first bellows 4, the connection of the second bellows 5, first
Bar 6, the second connecting rod 7, engaging lug 8.
A kind of bellows expansion joint, the bellows expansion joint include the first tube coupling 1, the second tube coupling 2, third tube coupling 3, the
One bellows 4, the second bellows 5, one end of first tube coupling 1 are connect with one end of first bellows 4, and described first
One end of tube coupling 1 is caught in one end of first bellows 4, and rivets over rivet, forms connection.
The other end of first bellows 4 is connect with one end of second tube coupling 2, and connection type is also mutually to entangle
Rivet interlacement again, the other end of second tube coupling 2 are connect with one end of second bellows 5, the connection type and above-mentioned
Connection type is identical.The other end of second bellows 5 is connect with one end of the third tube coupling 3, the connection type and upper
It is identical to state connection type.The bellows expansion joint further includes first connecting rod 6, the second connecting rod 7, the first connecting rod 6,
The both ends of second connecting rod 7 are equipped with screw thread, are connected between first tube coupling 1 and second tube coupling 2 by first connecting rod 6
It connects, is connected between second tube coupling 2 and the third tube coupling 3 by the second connecting rod 7.First tube coupling 1, the second tube coupling
2, third tube coupling 3 is equipped with engaging lug 8.As shown in the figure first connecting rod 6, the second connecting rod 7 both ends insertion engaging lug 8 after
The both ends of connecting rod screw nut respectively and achieve the purpose that connecting rod is fixed, the first connecting rod 6, the second connecting rod 7 at
Annular array distribution.
The application is provided with the first bellows 4, the second bellows 5 is able to satisfy the compensation of axial displacement, when needing to carry out diameter
To compensation when, unclamp the nut of 8 two sides of engaging lug, diametric compensation can be completed in this bellows expansion joint, when
After completing good docking, nut is tightened.The present apparatus is provided with the first bellows 4, the second bellows 5 can bear certain radial compensation
Ability can be carried out dislocation after the first bellows 4,5 spreading of the second bellows.
