Abstract

An inner static electricity eliminating control valve for organic solvent delivery pipelines is disclosed. The inner static electricity eliminating control valve is to be installed on and connected to an organic solvent delivery pipeline, to eliminate the inner static electricity generated by the organic solvent inside the organic solvent delivery pipeline. The inner static electricity eliminating control valve includes a valve casing, a main valve chamber, a pneumatic valve, a subsidiary valve chamber, a check valve, a static electricity export mechanism and a solvent export portion, wherein, the pneumatic valve can periodically apply pressure toward the organic solvent inside the main valve chamber, so that the organic solvent inside the main valve chamber can be delivered periodically through the check valve to the subsidiary valve chamber, and during this process, the static electricity export mechanism will export and eliminate the static electricity existing in the organic solvent.
