V-shaped sealing ring structure with pressure balance groove

Abstract

The utility model relates to a kind of V-shaped sealing ring structure with pressure balance groove, including sealing ring assembly, sealing ring assembly includes outer ring, inner ring and fixed screw, the outer wall of inner ring is provided with square protrusion one, and the inner wall of outer ring is provided with square protrusion two, square protrusion one and square protrusion two are alternately distributed, and square protrusion one and square protrusion two form pressure balance channel one between, the outer wall of inner ring is provided with triangular protrusion one.The fluid of the sealing ring high-pressure side can be gradually weakened by pressure balance channel one and pressure balance channel two, realize pressure compensation, the pressure difference on both sides of sealing ring can be balanced, thereby the excessive deformation of sealing ring caused by the high pressure of sealing ring single side can be avoided, leading to sealing ring sealing failure, short service life problem, the service life of sealing ring can be extended, and pressure balance channel one and pressure balance channel two are used in cooperation, and pressure balance effect is better.
