description	FIELD: mining art; cementing of casing in well. SUBSTANCE: valve has body 1 inside which bush with seat for shut-off member 5 is mounted for limited motion. Stem 6 of shut-off member is passed through partition 7. Fitted on stem between shut-off member 5, partition 7 and washer 8 on tail-piece of stem are springs 9 and 10. Thrust spring 12 is fitted in slot 11 of bush. In lowering the casing string, valve is open at all times and in case of emergency, shut-off member 5 closes the inner chamber of casing string. In cementing the casing, bush is locked by thrust spring 12 and valve operates as standard check valve. EFFECT: shut-off of string space in an emergency. 1 dwg Изобретение относится к горному делу и предназначено для цементирования обсадных колонн в скважине. Цель - перекрытия трубного пространства при возникновении аварийной ситуации. Клапан содержит корпус 1, внутри которого с возможностью ограниченного перемещения установлена втулка с седлом под запорный орган 5. Шток 6 запорного органа пропущен через перегородку 7. Между запорным органом 5, перегородкой 7 и шайбой 8 на хвостовике штока продеты пружины 9 и 10. В паз 11 втулки посажена пружина 12. При спуске колонны клапан постоянно открыт, а при возникновении аварийной ситуации запорный орган 5 перекрывает внутреннюю полость обсадной колонны. При цементаже колонны втулка фиксируется упорной пружиной 12 и устройство работает как обычный обратный клапан.
