摘要： A double-acting switch valve includes a mounting bracket and two mutually backup sealing assemblies disposed on the mounting bracket, each of the two sealing assemblies including a carbon rod and a carbon rod moving assembly, the carbon rod moving assembly being configured to translate, and elevate or lower the carbon rod so as to block or open a metal liquid channel between two metal liquid furnaces. Two sealing assemblies which are mutually replaceable, where when the carbon rod on one of the sealing assemblies is worn down, the other sealing assembly may take its place to block the metal liquid outlet again via the carbon rod; and then the worn-down carbon rod is renewed. This design eliminates the time taken for replacing the carbon rod and can reduce the amount of the metal liquid discharged via the metal liquid outlet during replacement of the carbon rod.
