Sleeve type drain valve is used to drain the volume fluid and release pressure when string testing finished. The ports in the sleeve of drain valve will be sealed with two sets of O rings before running in well, and the sliding sleeve and rotating nut are locked by two screws in order to keep the sliding sleeve tighten in course of downhole operation, attach drain collar after testing finished, rotate the rotating nut to make the sliding sleeve moves up until when the ports in the sleeve are aligned with the ports in the body of the tool, the fluid may be drained.
