AI Technical Summary
Technical Problem
Existing PTFE waterproof conical gaskets are prone to slight deformation under long-term continuous water pressure, which leads to a decrease in the fit of the sealing surface and loosening, affecting sealing performance and service stability.
Method used
A self-tightening polytetrafluoroethylene waterproof conical gasket was designed, comprising a conical gasket body, a fixing edge, a tight outer liner and an inner liner, inner and outer elastic rings and a buffer structure. Pressure is transmitted through the deformation of the buffer to enhance the sealing effect and achieve the self-tightening function.
Benefits of technology
It improves the sealing effect, reduces the risk of deformation and loosening under long-term pressure, and extends the service life of the gasket.

Abstract
The utility model relates to a self-tightening polytetrafluoroethylene waterproof conical gasket, including conical gasket body, fixed clamping edge and close outer lining, the outside of close outer lining is provided with close inner lining, the middle part of fixed clamping edge is provided with fixed clamping groove, the inside of fixed clamping groove is provided with outer elastic ring and inner elastic ring, the outer elastic ring is located one side of inner elastic ring, and the inner wall of outer elastic ring and the outer wall of inner elastic ring all are provided with antiskid line. In the utility model, the close outer lining and the close inner lining can be inserted into the conical gasket body through the fixed clamping edge, the close outer lining and the close inner lining improve the pressure resistance of the conical gasket body, when receiving greater pressure, the conical gasket body can be more closely attached to the sealing surface, the sealing effect is enhanced, the greater the pressure, the more reliable the sealing, so that the self-tightening effect is achieved, the type change and loosening generated by long time pressure bearing can be reduced, and the service life of the gasket can be prolonged.
