Description
Technical field
The utility model belongs to rubber molded product.
Background technology
Each equipment interface of nuclear power station diesel engine system needs bending rubber joint to provide flexible connection, to reduce between port
The stress and mechanical oscillation that range error, angular error generate, and it is 1.0 × 10 that can absorb energy in accumulative irradiation5Gy conditions
Lower effectively conveying oil, water or oil-water mixture.
At present, there are no dedicated flexible ball-type elastomer connector, only non-nuclear powers in the mating rubber parts of China's nuclear power station
The bending rubber joint and product standard of function, such as the spherical through elastomer connector of each model listed in GB/T-2010.It is this
The structure of spherical through elastomer connector is that nylon cord cloth is attached to the sizing material based on natural rubber as enhancement layer folder
Between inside and outside glue-line.Reinforcing cord cloth used in the elastomer connector of this structure is in the internal pressure that axially and radially can bear
Apparent uneven, thickness is thicker, product flexibility is poor, and flexible resistance is poor, and the poor-performing of resistance to nuclear radiation of natural rubber, in core
Service life is short in power station, frequently replaces and the spoke that disappears is a pretty troublesome operating process.Make great efforts development clean energy resource in China
It is wanted under the guidance of go-global strategy policy with nuclear power, nuclear power technology and related matching component gesture of the research with independent intellectual property right
It must go, the wherein special flexible ball-type elastomer connector of nuclear power station is exactly one of important rubber matching component therein.
Invention content
The purpose of this utility model be develop a kind of dedicated device port radial displacement≤25mm to be connected of nuclear power station and
Angular displacement≤25 ° adapt to accumulation irradiation dose 1.0 × 105It remains to keep under the conditions of Gy effectively to convey oily, water or grease mixes
Close flexible single ball-type elastomer connector of liquid.
To achieve the above object, the technical solution of the utility model is to provide a kind of flexible single ball-type rubber of used in nuclear power station
Connector, it has the stupefied single spherical through enhancing rubber parts of the anti-pull-off ring convex of rigidity for port, by inner glue layer, enhancement layer, outer
Glue-line is formed；The main body sizing material of the inner glue layer is nitrile rubber；The main body sizing material of outer glue-line is neoprene；The enhancement layer
It is formed for be laminated alternate with nylon cord cloth of 2 ~ 4 layers of polyamide fibre silk fabric；The surface of enhancement layer fabric is coated with the increasing of neoprene
Viscous transition zone.
Compared with known technology, the utility model uses nitrile rubber to do inner glue layer, use neoprene for outer glue-line, adopt
As enhancement layer and thickening transition processing has been done by the use of polyamide fibre silk and nylon cord fabric, has made the media-resistant of whole rubber parts, it is resistance to
Aging, radiation resistance, globality, flexibility, flexible resistance can significantly improve, and axially and radially load performance is balanced,
Service life and physical property have reached design and use requirement, have filled up the blank of China's nuclear power ball-type elastomer connector.
Description of the drawings
Fig. 1 is the vertical profile structure diagram of the utility model.
The convex stupefied anti-pull-off ring 6- flanged joint snap rings of 5- of 1- inner glue layers 2- enhancement layer 3- outer glue-lines 4- in figure.
Specific embodiment
The utility model structure and manufacturing process is described in detail below in conjunction with attached drawing：The utility model is port as shown in the figure
With the anti-pull-off ring of rigidity（5）, it is convex stupefied（4）Single spherical through enhancing rubber parts, by inner glue layer（1）, enhancement layer（2）, it is outer
Hand over layer（3）It forms.
Its manufacturing technology steps is as follows：
1. external coordination manufactures vulcanization mold and the anti-pull-off ring of rigidity（5）.
2. prepared by rubber compound：Inner glue layer is respectively cooperating with and is kneaded by component design（1）, diplomatic layer（3）, thickening transition zone glue
Liquid sizing material is spare.
3. the preparation of tackified finish glue：It will be thin through rubber mixing machine through thickening transition zone glue rubber compound obtained by step 2
Lead to, shred into liquid cement agitation tank, it is spare to go out tank after 8 hours using gasoline-ethyl acetate as stirring solvent.
4. enhancement layer（2）Thickening gluing：Polyamide fibre silk fabric and nylon cord cloth surface are applied on glue spreader cut to pieces through
Glue obtained by step 3, it is spare after dry.
5. inside and outside glue-line rubber compound rolling out film：Internal, outer glue-line is depressed into 3mm with rubber compound on calender respectively
Slice is spare.
6. enhancement layer（2）It cuts out：It is cut out by art work sheet and model spare.
7. molding：It covers and is covered through step 5 gained inner glue layer on mold core（1）, after alternate 2 ~ 4 layers of cladding through step 4 institute
Polyamide fibre silk fabric and nylon cord cloth are obtained, after cladding through step 5 gained outer glue-line（3）The two of feed-through after hand roller layer-by-layer rolling
It is inserted in the anti-pull-off ring of rigidity in a port（5）The anti-pull-off ring of port glue cladding rigidity of turning up（5）.
8. whole vulcanization：It will be placed in the external mold of sulfurizing mould in vulcanizing press through step 7 unvulcanized part after molding
On to vulcanize under the conditions of 151 DEG C of 120min.
9. mould unloading, flash trimming.
