Claim 0:
1. A double-acting switch valve, comprising
a mounting bracket and two sealing assemblies disposed on the mounting bracket, each of the two sealing assemblies comprising 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; wherein
the carbon rod moving assembly comprises a lift mechanism having a carbon rod clamping device, and a translational mechanism for driving the lift mechanism to perform a translational movement;
a metal liquid control position is provided on the mounting bracket;
one of the two sealing assembly resting at the metal liquid control position brings the carbon rod to move up or down via the lift mechanism to block or open the metal liquid channel between the two metal liquid furnaces;
the two sealing assemblies are symmetrically disposed; and
when the carbon rod of the one of the two sealing assemblies is worn down, the sealing assembly exits the metal liquid control position via cooperation between the lift mechanism and the translational mechanism, and another of the two sealing assemblies moves to the metal liquid control position via cooperation between the lift mechanism and the translational mechanism.
