A COMBINATION STRAINER AND BLOCKING VALVE FOR LIQUID METAL SYSTEMS
Technical Report
·
OSTI ID:4153699
A 3-in. pipe-size combination valve and strainer device performed satisfactorily when tested in a sodium system. The device provided a means of removing an in-line strainer element from the system without draining the sodium and alternately served as a plug type blocking valve. Tests were conducted over a temperature range of 500 to 950 deg F and system pressures of 0. 5. and 10 psi at NaO contents of 50 to 400 ppm. The strainer element was isolated from the system by freezing the sodium around the valve plug. The time required to freeze the sodium was found to be primarily a function of system temperature, a typical value being 75 min for a system temperature of 800 deg F. (auth)
