Cleaning.Seriously affect working efficiency.
Utility model content
For the container door closure and the easy binding material of door closure flange for solving the prior art, cleaning seriously affects the skill of working efficiency
Art problem, the utility model provide a kind of labyrinth plug type manhole door closure to solve the above problems.
A kind of labyrinth plug type manhole door closure, the door closure including being set to hole pipe end opening, in the outer wall of the hole pipe
Equipped with first flange, the edge of the door closure is equipped with second flange, removably connect with the first flange, the door closure leans on
Side in the nearly hole pipe is inclined equipped with multi-disc soft board, and the soft board is abutted with the inner wall of the hole pipe end opening,
Soft board described in multi-disc constitutes cone cylinder along hole inside pipe wall annular array.
In a kind of preferred embodiment of plug type manhole door closure in labyrinth provided by the utility model, the edge of the door closure
Equipped with a circle extension edge, the extension edge is arranged around the hole pipe outer wall, and is equipped with the second flange in end, and described
First flange removably connects.
In a kind of preferred embodiment of plug type manhole door closure in labyrinth provided by the utility model, the first flange,
Sealing ring is equipped between the second flange.
In a kind of preferred embodiment of plug type manhole door closure in labyrinth provided by the utility model, the door closure is close to institute
It states the side in the pipe of hole and is equipped with heat preservation sandwich layer, the soft board is set to the outer wall of the heat preservation sandwich layer, is open with the hole pipe end
The inner wall at place abuts, and is arranged in cone cylinder.
In a kind of preferred embodiment of plug type manhole door closure in labyrinth provided by the utility model, the heat preservation sandwich layer is
Arc convex towards inside the hole pipe, the soft board are fixed thereon with the angle tangent with the heat preservation sandwich layer outer wall.
Compared to the prior art, the labyrinth plug type manhole door provided by the utility model is covered with the extension edge,
It connects flange in the outer wall of the hole pipe, avoids material and flange contact.On the other hand, it is additionally provided with the soft board, plays two
The effect of grade sealing, prevents the inner edge between material and the door closure and the hole pipe from contacting.Further, the insulating layer
Extrados surface can also reduce the accumulation of material.Under each component cooperation, reaches the degree substantially without cleaning, substantially increase life
Produce efficiency.
Detailed description of the invention
Fig. 1 is the cross-sectional view of plug type manhole door closure in labyrinth provided by the utility model；
Fig. 2 is the partial enlarged view of Fig. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.
It is the cross-sectional view of labyrinth plug type manhole door closure 1 provided by the utility model respectively please refer to Fig. 1, Fig. 2,
And its partial enlarged view.
The labyrinth plug type manhole door closure 1 is set at 2 distal opening of hole pipe.
The outer wall of the hole pipe 2 it is circular be fixed with first flange 21.Based on the labyrinth plug type manhole door closure 1
For circular door closure 3, edge is equipped with a circle extension edge 31, is equipped with a circle second flange 32 in the end of the extension edge 31.
31 sets of the extension edge outer walls in the hole pipe 2, the two clearance fit.The second flange 32 and described first
Flange 21 is bolted, and the first flange 21 is equipped with sealing ring 22 between two flanges.
The door closure 3 is equipped with the insulating layer 4 of one layer of arc-shaped convex, including insulating layer close to the side of the hole pipe 2
Outer wall 41, the internal heat preservation filler 42 filled.
The surface of the insulating layer outer wall 41, with the angle tangent with it, circular is equipped with multi-disc soft board 5.Described in multi-disc
The structure that cone barrel is integrally formed of soft board 5 is abutted with the inner wall at end of the hole pipe 2.
Compared to the prior art, the labyrinth plug type manhole door closure 1 provided by the utility model is equipped with the extension edge
31, it connects flange in the outer wall of the hole pipe 2, avoids material and flange contact.On the other hand, it is additionally provided with the soft board 5, is risen
To the effect of secondary seal, prevent the inner edge between material and the door closure 3 and the hole pipe 2 from contacting.Further, the guarantor
The extrados surface of warm layer 4 can also reduce the accumulation of material.Reach the degree substantially without cleaning, substantially increases production effect
Rate.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass similarly includes within the scope of patent protection of the utility model.
