摘要： A shut-off valve has a housing, a wedge displaceable in the housing by a spindle, a housing opening, a cover arranged to close the housing opening and provided with a pipe, a locking screw inserted in the pipe for guiding, sealing and abutting of the spindle, and a supporting ring arranged between an outer end face of the cover pipe and an aligned collar of the screw and provided with two opposite supporting legs which abut with their lower supporting surfaces from above against a housing edge region which is adjacent to the cover pipe, so that during tightening of the locking screw which clamps the spindle collar and outwardly seals the spindle, simultaneously the cover is fixedly clamped with the housing.
