Embodiment
The exemplary embodiment of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
A kind of water-turbine top cover drainpipe cheats attachment structure with machine, including：Drainpipe 1, elbow 2, intubation 3 and sealing 4；
Drainpipe 1 is connected with the first end of elbow 2；The first end of intubation 3 is connected with the second end of elbow 2 by flange, be intubated 3 the
In the opening in two ends insertion machine hole 5；Sealing 4 is set in the periphery of intubation 3, and sealing 4 is fixedly connected with machine hole 5；Wherein, it is close
Envelope portion 4 includes compressed part 41 and pad 42, and compressed part 41 is connected by connector with machine hole 5, and pad 42 is arranged on compressed part
Between 41 and machine hole 5, pad 42 is provided with the first sealing ring 6 with 3 relative inner surfaces of intubation, and pad 42 cheats 5 relative sides with machine
Face is provided with the second sealing ring 7, and compressed part 41 is provided with the 3rd sealing ring 8 with 3 relative inner surfaces of intubation；The sealing of intubation 3 and first
It is interference fit between the sealing ring 8 of circle 6 and the 3rd.
The attachment structure that the present embodiment is provided is mainly used in connection water-turbine top cover and cheated with machine, but is not limited to this, and it is also
The structure for carrying out vibration damping, buffering can be needed to be attached to other.
As shown in figure 1, one end of drainpipe 1 and the top cover of the hydraulic turbine are connected, the other end is connected with the first end of elbow 2,
Connected mode can be that welding can also be bolt connection, and the second end of elbow 2 and the first end of intubation 3 are equipped with flange, two
Individual flange is attached by bolt, in order to ensure the sealing of connecting portion can also be set between two flanges pad or
Sealing ring.Compressed part is fixed on machine hole 5 by screw or bolt connection, and the pad between compressed part and machine hole is rubber blanket
Piece, to play sealing function, but is not limited to this, and it can also can play the pad of sealing function for other.First sealing ring 6
Leak can be prevented to being sealed between intubation 3 and pad by being arranged on pad and being intubated 3 inner surface；Similarly, the second sealing ring
7 gaps being used between gasket seal and machine hole, the 3rd sealing ring 8 is used to seal the gap between compressed part and intubation 3.In order to
Ensure that there is good sealing, match somebody with somebody interference is set between the sealing ring 6 of intubation 3 and first, the sealing ring 8 of intubation 3 and the 3rd
Close.
The present embodiment will be intubated 3 the second end by setting intubation 3 and being connected the first end for being intubated 3 with the flange of elbow 2
It is fixedly connected in insertion machine hole rather than with machine hole, so when the hydraulic turbine produces vibration, the relative machine of intubation 3 can be passed through
The motion in hole carrys out the destruction that buffering vibration is produced to attachment structure；In addition, the connecting portion in intubation 3 and machine hole sets sealing
4, and sealing 4 is fixedly connected with machine hole, when being intubated 3 with the relative motion of machine hole, sealing 4 can ensure intubation 3 and machine
The sealing of hole junction prevents moisture from leaking.
Alternatively, machine cheats 5 ends and is provided with adpting flange 9, and compressed part 41 is connected with adpting flange 9 by connector, and second
Sealing ring 7 is arranged on the side relative with adpting flange 9 of pad 42.
As shown in figure 1, compressed part 41 is cyclic structure in the present embodiment, compressed part 41 and adpting flange 9 by screw or
Person's bolt connection, can be such that sealing 4 is fixed on machine hole by the connection of compressed part 41 and adpting flange 9.The second of intubation 3
Sealed in end insertion machine hole 5 and by sealing 4, under the continuous effect of vibration of the hydraulic turbine, intubation 3 can be according to stress
Situation cheats motion to buffer suffered power relative to machine, the company in 4 pairs of intubations 3 of sealing and machine hole in 3 motion processes are intubated
Connect position and play sealed effect, prevent leak, connect simultaneously because intubation 3 is inserted into machine hole rather than fixed with machine hole
Connect, so can effectively buffer the vibration of the hydraulic turbine.
Alternatively, the cross section of the first sealing ring 6, the second sealing ring 7 and the 3rd sealing ring 8 be rectangle or triangle or
Person is circular.
As shown in figure 1, the cross sectional shape of the first sealing ring 6, the second sealing ring 7 and the 3rd sealing ring 8 can in the present embodiment
Think a variety of, for example, rectangle, triangle, circle etc..Exemplary the first sealing ring 6 and the second sealing ring 7 of providing in Fig. 1
Rectangular cross-section, the section of the 3rd sealing ring 8 is triangle, but not limited to this, in actual use, can be selected as needed
Its cross sectional shape.
Alternatively, pad 42 is provided with least one first sealing ring 6 and/or at least one second sealing ring 7, and/or,
Compressed part 41 is provided with least one the 3rd sealing ring 8.
As shown in figure 1, the sealing in order to ensure sealing 4, prevents the phenomenon of leak, can by the first sealing ring 6,
Second sealing ring 7 and the 3rd sealing ring 8 are set to multiple tracks.It is exemplary by the first sealing ring 6, the second sealing ring in the present embodiment
7 and the 3rd sealing ring 8 be respectively arranged one, can be configured as needed in actual use.
Alternatively, the 3rd sealing ring 8 is right angled triangle, and the 3rd sealing ring 8 is arranged on the friendship of compressed part 41 and pad 42
At boundary, the side of the right-angle side and pad 42 of right angled triangle fits, and another right-angle side of right angled triangle is with inserting
Pipe 3 fits.
As shown in figure 1, in order to prevent the intersection of compressed part, pad and 3 threes of intubation poorly sealed, by the 3rd sealing ring
8 are arranged on compressed part, pad and the intersection for being intubated 3.The cross section of the 3rd sealing ring 8 is arranged to right angled triangle simultaneously,
So that a right-angle side of right angled triangle is arranged between compressed part and pad, another right-angle side is arranged on compressed part and intubation
Between 3, the sealing problem in both direction is so ensure that simultaneously.
Alternatively, drainpipe 1 is connected with the first end of elbow 2 by flange.
As shown in figure 1, the first end of the end of drainpipe 1 and elbow 2 is equipped with flange arrangement, drainpipe in the present embodiment
1 be bolt-connected to the flange arrangement of the first end of elbow 2 together with.While the sealing in order to ensure connecting portion, can
To set sealing ring between the flange arrangement of the end of drainpipe 1 and the flange arrangement of the first end of elbow 2.
The present embodiment is intubated by setting and is connected the first end of intubation with elbow flange, and the second end of intubation is inserted
It is fixedly connected, so when the hydraulic turbine produces vibration, can be cheated by being intubated relative machine in machine hole rather than with machine hole
Motion carrys out the destruction that buffering vibration is produced to attachment structure；In addition, sealing is set in the connecting portion that intubation and machine are cheated, and will
Sealing is fixedly connected with machine hole, and when intubation cheats relative motion with machine, sealing can ensure that intubation cheats junction with machine
Sealing prevents moisture from leaking.
It is described above, the only embodiment of the embodiment of the present invention, but the embodiment of the present invention protection domain not
This is confined to, any one skilled in the art can think easily in the technical scope that the embodiment of the present invention is disclosed
To change or replacement, it should all cover within the protection domain of the embodiment of the present invention.Therefore, the protection domain of the embodiment of the present invention
It should be based on the protection scope of the described claims.
