Provided is a dual-sealing valve including a power cylinder having a driving shaft, a valve body including first and second valve members, and a seal plate assembly within the valve body, capable of firmly sealing. Here, the first valve member has a shaft bore allowing the driving shaft to penetrate therethrough, and the second valve member has two valve holes disposed to face each other. The seal plate assembly has a driving frame connected to the driving shaft, and a plurality of roller assemblies are disposed around the driving frame. The seal plate assembly has two seal plates respectively disposed between the valve body and two surfaces of the driving frame. Each of the seal plates has a plurality of driving grooves corresponding to the roller assemblies. The driving shaft drives the seal plate assembly in order to seal the valve holes with a sealing force formed between the roller assemblies and the driving grooves as the roller assemblies and the driving grooves are used. |
