Abstract
A hollow O-shaped rubber and plastic sealing ring consists of a round rubber and plastic ring and a round cavity. The production method of the hollow O-shaped rubber and plastic sealing ring is that: an extruder is firstly used for producing a hollow rubber and plastic pipe, then water-soluble material is utilized to produce a connecting piece, then the connecting piece is used for transitionally connecting the two ends of the hollow rubber and plastic pipe, a hot-melting vulcanizer is utilized to carry out hot vulcanization connection, two fabrication holes are arranged on the hollow rubber and plastic pipe wall after integral connection, water is also filled into the hollow rubber and plastic pipe, the connecting piece is discharged after being dissolved, and finally hot melt adhesive is used for filling the two fabrication holes. The hollow O-shaped rubber and plastic sealing ring not only can greatly reduce the machining and assembling accuracy requirements of the sealing ring, but also can reduce the material utilization amount, when being arranged into a seal groove, even if a certain error is generated between sealing joint surfaces, the hollow O-shaped rubber and plastic sealing ring can better adapt to generate corresponding deformation, so the sealing ring is ensured to have enough and uniform contact pressure, the hollow O-shaped rubber and plastic sealing ring has excellent sealing performance, and removes the technological bias that the hollow O-shaped rubber and plastic sealing ring can not generate a hollow structure.
Description
[technical field]
The utility model relates to rubber-plastic sealing ring, relates 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.
[model utility content]
The purpose of this utility model provides a kind of hollow O shape rubber-plastic sealing ring.
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, again the water in the hollow O shape rubber-plastic sealing ring is drained after to be connected the dissolving to wherein water filling;
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 utility model has been broken the technology prejudice that O shape rubber-plastic sealing ring can not be produced hollow structure.

[embodiment]
Describe mode of execution of the present utility model in detail below in conjunction with accompanying drawing:
Described hollow O shape rubber-plastic sealing ring, as shown in Figure 1 and Figure 2, its integral body is circular, and its cross section is made up of circular rubber ring 1 and circular cavity 2, and circular cavity 2 is positioned at the center of circular rubber ring 1, and concentric with circular rubber ring 1.
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 4 earlier with extruder;
2. according to circular cavity 2 size requirements, with material compacting link 3 soluble in water, as shown in Figure 4;
3. according to the hollow circular rubber plastic pipe 4 of the length of run clip of hollow O shape rubber-plastic sealing ring, connecting end faces 5 in two of hollow circular rubber plastic pipe 4 adds and is coated with adhesion glue, link 3 is inserted in the endoporus of hollow circular rubber plastic pipe 4, make two of hollow circular rubber plastic pipe 4 connect end face 5 and realize preliminary the connection, get the early-products of hollow O shape rubber-plastic sealing ring, as shown in Figure 3;
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, again the water in the hollow O shape rubber-plastic sealing ring is drained after to be connected 3 dissolving to wherein water filling;
