ブ。[Scope of Claim for Utility Model Registration] A pull-out type submerged unit with a check valve that hangs down on a seat provided at the bottom of a liquid pumping column and is composed of a motor unit and a pump unit that allow handling liquid to flow through the inside of the casing. In the pump, a liquid drain valve is provided at the top of the pump casing and is closed by resiliently biasing a valve body, and a pump lifting wire is secured to one end of the valve body, and when the wire is hoisted, the fluid drain valve is closed by resiliently biasing the valve body. A liquid drain valve in a barrel of a retractable pump with a check valve, characterized in that the liquid drained in the liquid pumping column is discharged by opening the liquid drain valve by movement of the valve body against resistance.
