Abstract

The invention provides a low-leakage rate long-service life two-way live plugging and unplugging rapid disconnector under pressure, which comprises a male connector and a female connector, and devicessuch as a movable valve core, a static valve core, a sealing ring, a spring, a limiting bulge, a locating block and a through hole are arranged in the male connector and the female connector respectively. By the special design and cooperation of the above devices, the two-way plugging and unplugging under pressure and manual direct plugging and unplugging in the case of any pressure can be realized, such that the disconnector has the advantages of low leakage rate and long service life.

Description

technical field [0001] This patent relates to a two-way pressurized plug-in disconnector, in particular to a low-leakage, high-life two-way pressurized plug-in quick disconnect, which belongs to the field of electromechanics. Background technique [0002] In aerospace, oil and gas facilities, and heavy-duty hydraulic equipment, in order to improve operating efficiency, quick couplings that directly perform pipeline butt joint operations under pressure are required. However, the current pressurized plug-in series quick disconnects have problems such as only one-way pressurized operation, large plug-in force, large leakage rate, and short life, which do not meet the needs of special fields such as aerospace. Pull out force, leak rate and service life requirements. [0003] At present, most of the domestic fast hydraulic joints cannot realize two-way plugging and unplugging under pressure, and the pressure must be released when plugging and unplugging, and the leakage rate is ...
