Abstract
Ship pressure sealing device, support beam is installed between supporting plate, is provided with air admission hole among support beam, supporting plate and support beam are made of nylon material.The ship pressure sealing device of the present invention, using this structure, simplifies point compression ring process and a technique；Using nylon material, avoiding will also prevent supporting plate from producing high temperature deformation in welding process, supporting plate out-of-flatness be caused, so as to influence using effect；Manufacturing cost is higher.Again because the compression molding time is very short, labor productivity is drastically increased, considerably reduces the cost of product again.
Description
Technical field
The present invention relates to field of ship equipment, more particularly to ship pressure sealing device.
Background technology
Ship pressure sealing device is the conventional sealing device of ship, is often filled with lubricated sealing device of oil, water lubrication sealing
Put, the main sealing device such as mechanically-sealing apparatus supports the use, available for ship ship axle, the electric plating propulsion axle of ocean engineering ship
Etc. the sealing of rotary shaft, pressurized seal device by air sealing base, in air sealing base made of rubber opening in a ring
Implication capsule, it is inlaid in opening air bag and divides compression ring, and opening air bag is fixed and is sealed in the hermetic seal in air sealing base
Lid is formed, and current divides compression ring to be made up of stainless steel material, including two pieces be oppositely arranged be parallel to each other and shape, size are homogeneous
With and coaxial annular supporting plate, have backbar that is vertical with two supporting plates and being fixedly connected between two supporting plate center sections, supporting
There is air admission hole on beam, thus the cross section for dividing compression ring of the structure is in " H " shape.This structure divides compression ring process cumbersome,
Technological requirement is high；Also to prevent supporting plate from producing high temperature deformation in welding process, cause supporting plate out-of-flatness, influence using effect；System
Cause this higher.
The content of the invention
In order to overcome tradition to divide compression ring process cumbersome, technological requirement is high, also to prevent supporting plate from producing in welding process
High temperature deformation, cause supporting plate out-of-flatness, the deficiencies of manufacturing cost is higher, the invention provides a kind of ship pressure sealing device.
The used to achieve the above object technical scheme of the present invention is：Ship pressure sealing device, install between supporting plate
Support beam, support beam centre are provided with air admission hole.
The supporting plate and support beam are made of nylon material.
The ship pressure sealing device of the present invention, using this structure, simplifies point compression ring process and a technique；Using
Nylon material, avoiding will also prevent supporting plate from producing high temperature deformation in welding process, supporting plate out-of-flatness be caused, so as to influence to use
Effect；Manufacturing cost is higher.Again because the compression molding time is very short, labor productivity is drastically increased, is greatly lowered again
The cost of product.
Brief description of the drawings
Fig. 1 is the structure chart of ship pressure sealing device of the present invention.
Embodiment
The structure of ship pressure sealing device of the present invention is as shown in figure 1, install support beam 3, in support beam 3 between supporting plate 1
Between be provided with air admission hole 2, supporting plate 1 and support beam 3 are made of nylon material.To make backbar 3 preferably connection and branch supporting plate
1, the inner surface radially of backbar 3 and outer surface are all the parabola type curved surfaces of depression, so can preferably eliminate point compression ring from
The stress of body in use.6 air admission holes 2, the minimum thickness and support of the radial direction of backbar 4 are radially provided with backbar 3
The ratio between width LT of plate 1 is 1/8, and this make it that the thickness of backbar 3 is relatively thick, substantially increases the intensity of point compression ring, can
The pressure being applied to from opening air bag both sides is preferably born, and opening air bag is strutted and is close in the side wall of gasbag chamber,
And because the thickness of backbar is thicker, point compression ring stability of itself is improved, does not produce twisted phenomena.
