Abstract
The utility model relates to a sealing ring, in particular to a polytetrafluoroethylene dual-sealing lip sealing ring device between various holes and shafts which need to be sealed, from which working fluids are spattered. The polytetrafluoroethylene dual-sealing lip sealing ring device is characterized in that mounting circular holes, sealing ring substrates, air side heat dissipation zones, fluid side heat dissipation zones, primary sealing lips, auxiliary sealing lips, oil return holes and leakage storage zones are arranged at the top and bottom symmetric positions of a mounting shaft by taking the mounting shaft as the center, wherein both sides of each leakage storage zone are provided with the primary sealing lip and the auxiliary sealing lip, and the oil return holes and the leakage storage zones are connected into a whole. The polytetrafluoroethylene dual-sealing lip sealing ring device has the advantages of simple structure, low cost, convenience in operation and use and simple preparation method, and an engine does not generate the phenomenon of machining vibration.
Description
Technical field: the utility model relates to seal ring, specifically is need seal the hole of the working liquid body that splashes and the teflon double-sealing lip seal coil apparatus between the axle various.
Background technique: growing along with product, the expansion of application is had higher requirement to the application of sealed product.Thereby the requirement to seal ring is also more and more higher, and single lip (or with a secondary lip) can not adapt to current form, so double-sealing lip seal structure is exactly a kind of new structure that designs for this demand.But the difficulty of processing of double-sealing procheilon structure can't be realized this technology.
The sealing of existing seal ring is the single lip secondary lip of a dustproof usefulness (or with) and forms a working surface (Fig. 2) with axle, so all be considered as single lip, the product lip of single lip seal has direct relation with the coaxality coaxial, that install between circular hole and the installation shaft of axle, require cooperation very accurate to the gap of installing between circular hole and the installation shaft, otherwise in use the eccentric wear phenomenon can appear, will lose seal action after long-time the use, cause product leakage.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, with low cost, easy for operation, the simple teflon double-sealing of preparation method lip seal coil apparatus preparation method.Model utility is achieved in that and comprises the installation circular hole, the seal ring matrix, and the air side heat dissipation area, installation shaft, the fluid side heat dissipation area, primary seal lip, identified areas, the auxiliary seal lip, spill port leaks the memory block.Symmetrical position up and down in installation shaft is provided with the installation circular hole, the seal ring matrix, and the air side heat dissipation area, installation shaft, the fluid side heat dissipation area, primary seal lip, the auxiliary seal lip, spill port leaks the memory block; The both sides of leaking the memory block are provided with primary seal lip, auxiliary seal lip, and spill port connects as one with the leakage memory block.The utlity model has following advantage: simple in structure, with low cost, easy for operation, the preparation method is simple, and motor does not produce worker's phenomenon of shaking.
Description of drawings: Fig. 1 is the utility model structural principle generalized section; Fig. 2 is that existing seal ring sealing is single lip structural principle generalized section.
Embodiment: comprise circular hole 1 is installed, seal ring matrix 2, air side heat dissipation area 3, installation shaft 4, fluid side heat dissipation area 5, primary seal lip 6, identified areas 7, auxiliary seal lip 8, spill port 9 leaks memory block 10.Symmetrical position up and down in installation shaft 4 is provided with installation circular hole 1, seal ring matrix 2, and air side heat dissipation area 3, installation shaft 4, fluid side heat dissipation area 5, primary seal lip 6, auxiliary seal lip 8, spill port 9 leaks memory block 10; The both sides of leaking memory block 10 are provided with primary seal lip 6, auxiliary seal lip 8, and spill port 9 connects as one with leakage memory block 10.Main sealing principle is: coaxality is being installed between circular hole 1 and the installation shaft 4 greatly and beat when big, little leakage appears as primary seal lip 6, there is small volume of fluid to leak into and leaks memory block 10 from flow side A, auxiliary seal lip 8 can be sealed in working liquid body and leak memory block 10 at this moment, and the high speed rotary by installation shaft 4 will leak working liquid body in the memory block 10 and get rid of by spill port 9 and get back to the a-quadrant under action of centrifugal force, in case the fluid stopping body leaks into air side B, reach sealing effect.And guarantee in the seal process to produce heat by fluid side heat dissipation area 5 and air side heat dissipation area 3 and can access and discharge and transmit.
