Power station scene is also met difficulty often when formally assembling, and needs that equipment adjustment, experiment is repeated sometimes.And main shaft maintenance sealing
Seal groove and sealing clamp are manufactured using general steel plate in the past, are influenceed that corrosion may be caused to occur by long-term storage, so as to influence
Assembling quality, service life, particularly palette are not fine, cause gas leak phenomenon to occur.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, there is provided a kind of simple structure, stability new type water high
Wheel machine overhauling sealing device.
To achieve these goals, the utility model uses following technical scheme：A kind of Novel water wheel machine overhauling sealing dress
Put, including sealing seat piece, air shroud part, sealing clamp and main shaft, the air shroud part lower section is provided with sealing seat piece, described
Air shroud part top is provided with sealing clamp, and the sealing seat piece upper surface is provided with the step matched with sealing clamp, and close
Envelope seat piece is fixedly connected with sealing clamp by fastener, and the sealing seat piece end is connected with main shaft, the air shroud part
End is provided with a groove, and the main shaft is provided with the projection with fit depressions.
On the other hand, the groove is U-shaped.
On the other hand, the fastener is the first fastening bolt.
On the other hand, the sealing seat piece is provided with fluid sealant with the binding face of sealing clamp.
On the other hand, the first stainless steel weld overlays are provided with the sealing seat piece and the binding face of air shroud part, it is described
The second stainless steel weld overlays are provided with sealing clamp and the binding face of air shroud part.
The beneficial effects of the utility model are：It is the utility model simple structure, easy to install, in seal receptacle and sealing
Overlay cladding is provided with pressing plate, service life is not only increased, the security of maintenance is also improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the longitudinal sectional view of air shroud part of the present utility model.
Fig. 3 is inspecting state schematic diagram of the present utility model.
Specific embodiment
In order that those skilled in the art are better understood from the utility model scheme, below in conjunction with the utility model reality
The accompanying drawing in example is applied, clear, complete description is carried out to the technical scheme in the utility model embodiment, it is clear that described
Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the reality in the utility model
Example is applied, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made all should
When the scope for belonging to the utility model protection.
As shown in Figure 1 and Figure 2, it is a kind of Novel water wheel machine overhauling sealing device, including seal receptacle 1, air shroud part 2, close
Envelope pressing plate 3 and main shaft 4, the bottom of air shroud part 2 are provided with sealing seat piece 1, and the top of air shroud part 2 is provided with sealing clamp 3, seals
The upper surface of seat piece 1 is provided with the step matched with sealing clamp 3, i.e. air shroud part 2 and sets and seal receptacle 1 and sealing clamp 3
In the cavity of formation, sealing seat piece 1 is fixedly connected with sealing clamp 3 by fastener 5, wherein the fastener 5 can be the
One fastening bolt, the first stainless steel weld overlays 8, the sealing are covered with the sealing seat piece 1 and the binding face of air shroud part 2
The second stainless steel weld overlays 9 are provided with pressing plate 3 and the binding face of air shroud part 2, stainless steel weld overlays are increased, can be extended
The service life of device, also increases sealing, and sealing seat piece 1 end is connected with main shaft 4, and air shroud part 2 and the phase of main shaft 4
Laminating, the end of air shroud part 2 offers a groove 6, and being shaped as its further groove 6 is U-shaped, is offered on main shaft 4 and the phase of groove 6
The projection 7 of cooperation, in compressed air air inlet shroud part 2, air shroud part 2 opens to both sides, favorably for such design
Closely held tightly in air shroud part 2 and main shaft, reduce gap.In actually maintenance leakage test, can be tested with air shroud
Frock 10 replaces main shaft 4, and the top of sealing clamp 3 is fixed in the side of air shroud test tool 10 by the second fastener 11, empty
Gap between gas shroud test tool 10 and two contact surfaces of air shroud part 2 is zero, and the effect of sealing is reached to verify, empty
When making air test in gas shroud part 2, the blowing pressure is 0.4~0.7MPa, is checked between sealing seat piece 1 and air shroud part 2
Whether gap is 0, design requirement is reached to ensure that both are closely sealed, to reach the requirement of water shutoff.
