Do you know all the knowledge of sealing ring? Today, the editor of quality fluorine rubber ring products will introduce some more.
The combined sealing ring includes an elastic ring, a support ring and a slip ring. The radial cross section of the elastic ring is a rectangular shape with an inner boundary of an arc. A sealing installation groove is opened on the inner wall of the valve body. The slip ring and the support ring are arranged from top to bottom. The lower side of the slip ring is arranged in order and embedded in the seal installation groove, the lower side of the slip ring is in contact with the upper side of the support ring, the inner cylindrical surface of the slip ring is slidingly sealed against the outer cylindrical surface of the valve stem, and the outer cylindrical surface of the slip ring is provided with a sliding seal. The radial cross section is a rectangular radial groove, the elastic ring is inserted in the radial groove in an interference type, the inner side wall of the elastic ring and the groove bottom diameter surface of the radial groove are sealed elastically, and the outer side wall of the elastic ring is in contact with the radial groove. The groove bottom diameter surface of the sealing installation groove is sealed elastically against each other, and the inner cylindrical surface of the support ring slides against the outer cylindrical surface of the valve stem.

A new type of combined sealing ring overcomes the problem that the O-ring in the dynamic seal is prone to torsional fracture, and improves the sealing performance, thereby improving the sealing performance and reliability of the valve.
The above is the small series of quality fluorine rubber ring products: a brief introduction to some knowledge about sealing rings.
