Gas-shielded siphonic valve |
摘要 |
A gas-shielded siphonic valve for controlling the flow of molten metal from one vessel to another. The valve includes a hollow conduit extending between the vessels above the surfaces of the metal therein with opposite ends thereof immersed in the metal in both vessels. An exhaust port permits evacuation of the inside of the conduit sufficiently to draw enough metal up into the conduit to effect a siphoning action between the vessels. A housing surrounding the conduit defining a chamber about the conduit for holding an inert gas. Any leaks in the system will neither break the siphoning action nor contaminate the metal. Varying the amount of vacuum applied to the system can be used to control the rate of flow of metal therethrough.
