High-performance multi-purpose tooth-shaped Y-shaped combined seal device

The invention discloses a high-performance multi-purpose tooth-shaped Y-shaped combined seal device. The combined seal device comprises a seal ring and an elastic body, the seal ring comprises an inner ring and an outer ring in an integrated mode, a seal groove is formed between the inner ring and the outer ring, the elastic body is arranged inside the seal groove, and multiple seal teeth are arranged on the outer wall of the inner ring and/or the outer ring. Through combining the seal ring and the elastic body and arranging the seal teeth on the outer wall of the seal ring, excellent seal performance is achieved, the combined seal device has the advantages of being good in seal performance, resistant to high pressure and corrosion, wide in application range and long in service life, the frequency of replacing a seal part is reduced under a high-pressure and high-corrosion working environment, the production cost is lowered, and meanwhile working efficiency is improved.
