The casing of the deep water sealed cabin only needs to be provided with a small plane, a certain thickness and corresponding installation threaded holes, the simple gas sealing valve can be installed, when the deep water sealed cabin works, an inflation pipe opening on the inflation nozzle is fixedly connected with an external inflation pipe, when external pressurization or negative pressure is needed, the inflation nozzle is unscrewed from the sealing seat through the installation threads, a gas passage can be formed after the o-shaped ring 2 is unscrewed, pressurization or negative pressure operation is carried out on the sealed cabin, when the gas pressure in the sealed cabin reaches a preset value, the inflation nozzle is screwed, the o-shaped ring 2 plays a sealing role, and at the moment, the sealing valve is in a sealing state.
3. Technical effects
The watertight valve can bear the water pressure of more than 5MPa and the common gas pressure of 0.1 MPa. The overall dimension can be adjusted according to the specific requirements of the underwater equipment. The installation is simple, convenient operation satisfies the watertight detection work demand before deep water equipment launching to reduce detection time and operation complexity greatly. In the test process of the underwater sealed cabin, after the watertight valve is installed, repeated operation is reduced for test operators, and the total time for airtight detection of the cabin body in the test process is reduced to 20% of the original time. And because the watertight valve has simple structure and high reliability of sealing mode, the processing cost and the maintenance cost of the watertight valve are greatly reduced.
