Zusammenfassung:	PURPOSE:To prevent leakage of valve seat by employing a nozzle-shape water- vapor double phase interface valve symmetrical against axis. CONSTITUTION:A valve seat 16 is made into cylindrical conically rising shape (nozzle-shape) where influence of thermal distortion is low. Consequently valve seat sealing performance is provided under such condition where considerable temperature difference exists between inlet and outlet of valve. Deterioration of temperature condition of each machinery in plant can be prevented by maintaining the valve seat sealing performance.
