摘要： A cementing tool for use in a well has a housing and a closing sleeve received thereabout. An operating sleeve is received in the housing and is interconnected with the closing sleeve so that movement in the operating sleeve will cause the closing sleeve to move. The closing sleeve is detachably connected to the housing and is movable from the first or open position to a second or closed position in which it covers cementing ports defined in the housing. The tool has a plurality of lock rings that are moved with the closing sleeve. A plurality of locking grooves are adapted to receive the lock rings such that the engagement of any of the lock rings with any of the locking grooves will prevent the closing sleeve from moving out of the closed position.
