Abstract

The invention belongs to the technical field of ship systems, and particularly relates to an anti-seawater-intrusion sealing device with an automatic pressure regulating function. The sealing device comprises an oil storage tank, a spring energized seal, glyd rings, an automatic pressure compensation device and a dust ring, wherein an oil injection oil way and the oil storage tank are formed in amain shell; the spring energized seal and the glyd rings are arranged between the main shell and an ejector rod; and the dust ring is arranged at the contact position between the top end of the main shell and the ejector rod, and the automatic pressure compensation device is mounted on the main shell. According to the sealing device, the pressure is automatically adjusted along with the change ofthe temperature during working, so that the pressure is controlled within a preset range, and the sealing performance of the product is ensured.

Description

technical field [0001] The invention belongs to the technical field of ship systems, and in particular relates to a seawater immersion-proof sealing device with an automatic pressure regulating function. Background technique [0002] The breather valve actuator is one of the important valves for the submarine to float and dive. Because the seal on the protruding rod is directly in contact with the seawater, if the seal is not good, the external seawater will leak into the submarine. If the circumstances are serious, the boat will be destroyed. . So it is of great significance to study its sealing. The traditional seal is a combination of O-ring and stuffing box. Although there are various brands of O-ring materials and stuffing boxes, they are all rubber in the final analysis, and their wear and tear is very serious after long-term use. Different degrees of leakage will occur, which will reduce the service life and require frequent replacement of sealing materials. Conte...
