Abstract

The invention discloses a dynamic sealing device of a high-pressure system. The device comprises a first end cover flange, a second end cover flange, a cavity flange, a second end cover flange, a connecting piece and a butt joint flange are sequentially installed in the same axial direction; a mounting cavity sealed and communicated is formed in the axial direction in the center of the first end cover flange, the cavity flange, the second end cover flange, the connecting piece and the butt joint flange; the inner diameters of the first end cover flange and the second end cover flange are the same, and Y-shaped sealing rings are installed on the inner walls of the first end cover flange and the second end cover flange; the inner diameter of the cavity flange is larger than the inner diameter of the first end cover flange, and a channel is formed in the side wall of the cavity flange. A high-pressure nitrogen barrier is formed between the high-pressure medium in the high-pressure industrial system and the atmosphere, and the reliability of dynamic sealing is improved; and high-temperature and high-pressure medium in an industrial device cannot leak into the atmosphere, so that a certain function part of the industrial device can be plugged and pulled under a high-pressure working condition, and an operation is carried out under a high-pressure operation working condition.

Description

technical field [0001] The invention relates to a dynamic sealing device, in particular to a dynamic sealing device of a high-pressure system. Background technique [0002] In energy, environmental protection, metallurgy, petroleum, chemical and other industrial fields, many industrial devices need to realize the insertion and extraction of certain functional components under high pressure conditions. For example, the ignition devices of industrial furnaces such as coal gasification furnaces and preheating furnaces need to be pushed into the furnace to ignite when the pressure in the furnace is relatively high. After the ignition is successful, the ignition device is pulled out of the furnace. At present, a certain functional part of many high-voltage industrial devices is fixedly installed on the industrial device. After the function is realized, the part cannot be pulled out in time, but will be damaged due to corrosion and ablation; for example, the ignition device will b...
