ABSTRACT
Within the composition of a hydraulic scheme, there are very often constructed waterconveying structures, either general or specific ones, which serve for conveyance of the water from one place to another. In order to enable their functioning, it is compulsory to use hydro-mechanical equipment, which serves for closing and opening of the openings of the water-conveying structures. In that way, in the case of hydraulic schemes with a dam, it is possible to realize a controlled discharge of water, as well as to regulate the level of the headwater, and also a controlled intake, conveying and utilization of water for certain objectives.
