Abstract
Blanking expansion joint is related to expansion joint field.Mainly solve to design the problems such as need to be together with flange integral replacing when existing blanking expansion joint mozzle is damaged.It includes left end pipe, right-hand member pipe, bellows, left end pipe right-hand member has Zola's plate, and right-hand member pipe left end, which has on right pulling plate, left end pipe, left end pipe flange, there is right-hand member pipe flange on right-hand member pipe, mozzle is located in the passage constituted after left end pipe, bellows, the connection of right-hand member pipe；Mozzle left end is fixed with connection ring, and connection ring is connected by screw with left end pipe adpting flange, and having on left end pipe adpting flange in the first O-ring mounting groove, the first O-ring mounting groove has the first O-ring；Being set on mozzle right-hand member outer wall in the second O-ring mounting groove, the second O-ring mounting groove has the second O-ring；Having on right-hand member pipe adpting flange in the 3rd O-ring mounting groove, the 3rd O-ring mounting groove has the 3rd O-ring.Advantage is that mozzle only changes mozzle when damaging.
Description
Technical field：
The utility model is related to expansion joint field, is specifically related to connect down between a kind of converter blanking flow tube and pipeline
Expect expansion joint.
Background technology：
The mozzle and left end Guan Douyu left end pipes of the blanking expansion joint connected between existing converter blanking flow tube and pipeline
Together, the dust granules material water conservancy diversion inside pipe wall easy to wear passed through during work out of mozzle causes mozzle to flange welding
Damage.Because mozzle and left end pipe all weld together with left end pipe flange, so needing integral replacing, waste many, increase
Addition sheet.Other dust granules material easily enters the space between mozzle and right-hand member pipe, bellows, and mill is caused to bellows
Damage, can also influence bellows to work more than build up of material.
The content of the invention：
Technical problem to be solved in the utility model is to provide a kind of mozzle and changes easy, and dust granules material will not
Bellows is impacted, it is ensured that the blanking expansion joint of bellows normal work.
What above-mentioned purpose was realized in：It includes left end pipe and right-hand member pipe, and ripple is connected between left end pipe and right-hand member pipe
Line pipe, the right-hand member of left end pipe is fixed with Zola's plate, and the left end of right-hand member pipe, which is fixed with right pulling plate, left end pipe, is fixed with left end tube method
Right-hand member pipe flange, in addition to mozzle are fixed with orchid, right-hand member pipe, the mozzle is located at by left end pipe, bellows, right-hand member pipe
In the passage constituted after connection；It is characterized in that：The connection ring of annular, institute are fixed with the left end outer wall of described mozzle
It is connected by screw between the connection ring and left end pipe adpting flange stated, first that annular is provided with left end pipe adpting flange is O-shaped
Enclose in mounting groove, the first annular O-ring mounting groove and be installed with the first O-ring, the method on left end pipe and converter blanking flow tube
During orchid connection, the first O-ring is in close contact with the flange in converter blanking flow tube, realizes sealing；On mozzle right-hand member outer wall
If being installed with the second O-ring in the second O-ring mounting groove of annular, the second annular O-ring mounting groove, the second O-ring and the right side
End pipe inwall is in close contact, the space that can so prevent dust granules material from entering between mozzle and right-hand member pipe, bellows；
It is provided with right-hand member pipe adpting flange in the 3rd O-ring mounting groove of annular, the 3rd annular O-ring mounting groove and is installed with the 3rd O
Type circle, the 3rd O-ring can be in close contact with the flange on pipeline, realize sealing.
The utility model has the advantages that：When mozzle is damaged, mozzle is only changed, changes easy, reduces and waste, drop
Low cost.Good sealing effect, dust granules material will not be impacted to bellows, it is ensured that bellows normal work.
Brief description of the drawings：
Fig. 1 is 13 flange for being in converter blanking flow tube in structural representation of the present utility model, figure, and 14 be on pipeline
Flange.
Embodiment：
Reference picture 1, it includes left end pipe 1 and right-hand member pipe 2, bellows 3, left end pipe is connected between left end pipe and right-hand member pipe
Right-hand member be fixed with Zola's plate 4, the left end of right-hand member pipe, which is fixed with right pulling plate 5, left end pipe, is fixed with left end pipe flange 6, right-hand member
Right-hand member pipe flange 7, in addition to mozzle 8 are fixed with pipe, the mozzle is located at by left end pipe, bellows, the connection of right-hand member pipe
In the passage constituted afterwards；It is characterized in that：The connection ring 9 of annular is fixed with the left end outer wall of described mozzle, it is described
Connection ring and left end pipe adpting flange between be connected by screw, be provided with left end pipe adpting flange annular the first O-ring
The first O-ring 10 is installed with mounting groove, the first annular O-ring mounting groove, the method on left end pipe and converter blanking flow tube
During orchid connection, the first O-ring is in close contact with the flange in converter blanking flow tube, realizes sealing；On mozzle right-hand member outer wall
If the second O-ring mounting groove of annular, be installed with the second O-ring 11 in the second annular O-ring mounting groove, the second O-ring with
Right-hand member inside pipe wall is in close contact, the sky that can so prevent dust granules material from entering between mozzle and right-hand member pipe, bellows
Between；The 3rd O-ring mounting groove of annular is provided with right-hand member pipe adpting flange, the is installed with the 3rd annular O-ring mounting groove
Three O-rings 12, the 3rd O-ring can be in close contact with the flange on pipeline, realize sealing.
