2 results about "External Lip" patented technology

A valve arrangement is configured to seal to a surface (e.g., of an enclosure). The valve arrangement carries a seal member having at least one flexible lip that presses against the surface when the valve arrangement is mounted to the surface. Some seal members have a flexible inner lip. Other seal members have a flexible outer lip. Still other seal members have both an inner lip and an outer lip. The lip(s) of the seal member inhibit water intrusion into the valve arrangement. The lip(s) of the seal member allow the a seal between the valve arrangement and the surface even when the surface is out of flat.

The utility model relates to self -lubricating rotary axle lip seal technical field discloses a kind of self -lubricating rotary axle lip seal assembly, including sealing lip block, the top of sealing lip block is provided with inner lip and outer lip, and the top of sealing lip block is provided with recess, the side of recess is sleeved with clamping ring, by setting the composite heat transfer structure of heat conduction ring, connecting column and reinforcing rib block in sealing lip block, so that the heat generated in the inner wall of sealing lip block can be efficiently transferred to the silicon oil in cooling groove, to realize rapid heat dissipation, significantly improve the cooling efficiency of sealing structure, by filling graphite and PTFE micro powder in fluorine rubber matrix, not only enhance the self -lubricating property of material, also improve wear resistance and service life, at the same time, cooling groove is used in cooperation with threaded fixing pipe, can periodically supplement silicon oil, further guarantee the cooling effect and sealing property of sealing structure, to effectively improve the overall strength, heat resistance and long-term stability of device.
