Description

technical field [0001] The invention relates to a sealing ring structure of a connecting sleeve, in particular to a novel structure of a sealing ring of a connecting sleeve of a cut-off valve, belonging to the technical field of hydraulic components. Background technique [0002] The sealing ring structure of the stop valve connecting sleeve is an important hydraulic component in the hydraulic system. Its main function is to play the role of connection and sealing. In the existing structure of the stop valve connecting sleeve, the connection of the stop valve connecting sleeve is not tight enough. , The defect that the sealing ring is easy to leak. Contents of the invention [0003] The purpose of the present invention is to provide a new shut-off valve joint sleeve sealing ring structure which has good connection effect and is not easy to leak. The loop is prone to leaking defects. [0004] The technical solution adopted by the present invention to solve the technical p...
