Problems solved by technology

[0004] The existing sealing means of the airtight cabin are mainly suitable for the dry environment on land. In the harsh environment at sea, the electrochemical reaction corrosion occurs on the metal contact surface, which leads to the problem that the equipment in the airtight cabin is easily filled with water vapor due to the impact of the surge. ; When the temperature (humidity) changes, there will be condensed salt mist inside, which seriously interferes with the tracking, locking and guiding functions of the photoelectric sensor; increase, and at the same time brought a lot of inconvenience in the harsh offshore environment

Abstract

The invention relates to an inflation sealing valve of a sealed cabin. A first seal ring is connected to an inner bore groove of the outer side of a first shell in a sleeved mode. A first sealing blocking cap is connected with the inner bore groove of the outer side of the first shell. A first sealing cover is connected with the first sealing blocking cap. The invention further relates to a deflation sealing valve and the sealed cabin. The inflation sealing valve and the deflation sealing valve of the sealed cabin are both mounted in a sealed cabin body. Through the inflation sealing valve, gas can be rapidly and directly inflated into the sealed cabin, and the sealed cabin can be instantly sealed after stop of inflation. The deflation sealing valve has the internal overpressure protectivecapability. The sealed cabin is good in sealing structure and prevents water vapor inflowing. The inflation sealing valve and the deflation sealing valve are each designed into an integrated assemblyand are convenient and fast to dismantle. All components are designed through general modularization. All the independent components can be replaced quickly to facilitate later maintenance.

Description

technical field [0001] The invention belongs to the technical field of gas sealing, and in particular relates to an inflatable sealing valve, a leaking sealing valve and a sealing cabin. Background technique [0002] Generally, the sealing maintenance methods of the air-inflated and deflated air-tight valves of the airtight cabin mainly include extrusion friction sealing and sliding friction sealing. Although there are differences in various sealing structures, they all achieve the effect of isolation and sealing by means of the frictional contact pressure of the extruded contact surface being greater than the real-time pressure inside the sealed cabin. A special spring with a certain length and stiffness is used to reversely squeeze and push the sealing ring and the internal contact of the sealing valve housing to form a pair of frictional contact pairs to realize the local surface pressure increase, thereby realizing the gas-tight operation inside the sealing cabin. The e...
