Check valve, английский

- Возвратный клапан
- Обратный клапан
- One that allows liquid to flow in one direction but not in the other.
- Generally a ball-type valve device placed in core barrels, soil samplers, or drill rods to control the directional flow of liquids. when used on a core barrel, the check blocks the downward flow of the circulation liquid through the inner tube. when used on a rod string, it blocks the upward flow of the circulation liquid through the rods.
- Any device that permits a liquid or gas to pass in one direction but automatically closes when the flow is stopped or reversed.
