Analysis and Improving of Pressure Seal Sealing Fixture

When the system of power plant is running, leakage is always occurred at the flanges of the valve and pipe. The plant will be stopped if the water leak to the environment. The technology of pressure seal sealing fixture can solve the problem that the plant will he stopped in service. According to numerous applications, the principle of pressure seal sealing fixture, the current status of the research and the key technique in operation were introduced. Through the application of the technology in a power plant, the main factors contribute to the success of containment were summed up. Aimed at the defieiene.v of fixture design, the way to improve the fixture and the method of designing a kind of new bolt pressure seal sealing tool were put forward, thus improving the sueeess rate of plugging
