Abstract
The invention relates to a hollow O-shaped rubber-plastic sealing ring and a preparation method thereof, consisting of a round rubber-plastic ring and a round hollow cavity. The preparation method comprises the following steps: firstly using an extruder to prepare a hollow rubber-plastic pipe, then using a water-soluble material to prepare a connecting piece, then using the connecting piece to connect the two ends of the hollow rubber pipe in a transition manner, using a hot melting vulcanizing machine to carry out adhesive hot-vulcanization connection, after integrally connection, arranging two technique holes on the wall of the hollow rubber-plastic pipe, injecting water into the hollow rubber-plastic pipe, dissolving the connecting part, then discharging the dissolved connecting part thoroughly and finally using hot melt glue to fill the two technique holes. The hollow O-shaped rubber-plastic sealing ring not only can greatly reduce the self processing accuracy and assembly accuracy of the sealing ring, but also can reduce the use amount of materials, after being arranged into a sealing groove, and also can well adapt to generating corresponding deformation even though the sealing combining surfaces have errors, thus ensuring the sealing ring to have enough and uniform contact pressure. The invention has excellent sealing performance, and breaks through the technical bias that the hollow O-shaped rubber-plastic sealing ring can not produce the hollow structure.
Description
[technical field]
The present invention relates to rubber-plastic sealing ring, relate in particular to annular rubber-plastic sealing ring.
[technical background]
Static relatively sealing occasion such as sealing, end face seal uses the sealing of the solid rubber-plastic sealing ring of ring-type more satisfactory between axis hole, not only good seal performance, and long service life, and it is the most frequently used a kind of seal ring.Existing O shape rubber-plastic sealing ring all is a solid construction, adopts the somatotype press moulding mode to obtain, and not only consumptive material is many for it, and has relatively high expectations to installing and using, and is unclear if flanging is handled, and then can influence sealability.If O shape rubber-plastic sealing ring can be designed to hollow-core construction, seal ring is stressed more reasonable so, and sealability can be better.Requirement on machining accuracy to seal ring and seal groove all can further relax simultaneously, and the certain deformation space is arranged behind the seal ring pressurized, can guarantee sealability.
[summary of the invention]
The purpose of this invention is to provide a kind of hollow O shape rubber-plastic sealing ring and preparation method thereof.
A kind of hollow O shape rubber-plastic sealing ring, it is characterized in that: integral body is closed circular, and its cross section is made up of circular rubber ring and circular cavity, and circular cavity is positioned at the center of circular rubber ring, and concentric with circular rubber ring.
The preparation method of described hollow O shape rubber-plastic sealing ring comprises the steps:
1. the sectional shape according to hollow O shape rubber-plastic sealing ring makes hollow circular rubber plastic pipe earlier with extruder;
2. according to the circular cavity size requirement, with material compacting link soluble in water;
3. according to the hollow circular rubber plastic pipe of length of run clip of hollow O shape rubber-plastic sealing ring, connecting end faces in two of hollow circular rubber plastic pipe adds and is coated with adhesion glue, link is inserted in the endoporus of hollow circular rubber plastic pipe, make two of hollow circular rubber plastic pipe connect end face and realize preliminary the connection, get the early-products of hollow O shape rubber-plastic sealing ring;
4. the hollow O shape rubber-plastic sealing ring that last step is obtained with hot melt vulcanizer and mould carries out the baking gummed, and the joint that makes hollow O shape rubber-plastic sealing ring is the vulcanizate integrator securely;
5. on the tube wall of hollow O shape rubber-plastic sealing ring, offer two auxiliary holes, and to wherein water filling, after to be connected the dissolving again
Water in the hollow O shape rubber-plastic sealing ring is drained;
6. fill up two auxiliary holes with hot melt adhesive at last, and repair draw together smooth.
Because O shape rubber-plastic sealing ring is designed to hollow structure, and provide concrete making method, earlier make hollow rubber plastic pipe with extruder, make link with the material that easily is dissolved in water again, connect with the two ends transition of link then hollow rubber plastic pipe, be with the glue hot vulcanization to connect with the hot melt vulcanizer, two auxiliary holes are offered in integrated connection back on hollow rubber and plastic tube wall, and water filling in it, again it is drained after to be connected the dissolving, fill up two auxiliary holes with hot melt adhesive at last, and repair and draw together smooth getting final product.This hollow O shape rubber-plastic sealing ring can not only reduce the machining accuracy and the assembly precision requirement of seal ring self significantly, and can reduce material consumption.After in hollow O shape rubber-plastic sealing ring is packed seal groove into, even there is certain error between the sealed faying face, the rubber ring of hollow also can be complied with well and produce corresponding distortion, guarantee that seal ring has enough and uniform contact pressure, this hollow and annular rubber-plastic sealing ring has excellent sealing ability, and using scope is extensive.
The present invention has broken the technology prejudice that O shape rubber-plastic sealing ring can not be produced hollow structure.
