Seals for use with low to medium viscosity fluids and related methods, apparatuses and systems

摘要

Seals for use in machinery and apparatuses to prevent leakage of fluids and methods, apparatuses and systems related thereto are provided. The seals can be used in apparatuses that use and/or process fluids having low to medium viscosity at low or high pressures while still preventing leakage of the fluids from the apparatus during processing.

主权项

1. A seal for use in an apparatus to prevent leakage of fluids from the apparatus, the seal comprising:
an integral annular body defining a space therebetween with an axis within the space and having an outer surface and an inner surface, the annular body comprising:
a center base forming a first end of the annular body;an inner arm extending outward from the center base at an angle such that the inner arm extends inward toward the axis within the space defined by the annular body;an outer arm extending outward from the center base at an angle such that the outer arm extends outward away from the axis within the space defined by the annular body;a cavity formed between the inner arm and the outer arm that extends to a trough formed by the center base, the cavity comprising a base cavity section and a neck cavity section with the neck cavity section forming the opening at the second end of the annular body and the neck cavity section comprising a width as measured between the inner arm and the outer arm that is less than a width of the base cavity section as measured between the inner arm and the outer arm; andthe inner arm and the outer arm having outer ends that form a second end of the annular body with the cavity having an opening at the second end, the outer end of the inner arm having a lead-in chamfer on the inner surface at the second end of the annular body and the outer end of the outer arm having a lead-in chamfer on the outer surface at the second end of the annular body.
