Introduction
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.

Construction

The drain valve consists of a ported body, sliding sleeve, and rotating nut, which controls the position of the sliding sleeve. The sleeve either covers or exposes the ports in the body of the valve.

The drain valve is installed between any two valves that may come out of the hole with pressure or fluid trapped between them. Pressure is relieved by installing the drain collar and drain nipples on the drain valve. Valves, lines, or sample bottles may be attached to the drain nipples depending on the desired disposition of the fluid in the string. After the drain collar assembly is attached, the ports in the tool are exposed by using a chain wrench or pipe wrench to rotate the drain nut, which moves the sliding sleeve.
When the ports in the sleeve are aligned with the ports in the body of the tool, the fluid may be drained.
It is also possible to trap a large volume fluid sample between two valves if a sample chamber of some kind (tubing, drill collar, etc.) is placed between the valves. In most cases, the drain valve would be run at the bottom of the sample chamber to facilitate transfer. This will not be a PVT sample.
