Description
совместно с кольцом 3 образуют жесткую монолитную систему. Выступающие над наружной поверхностью кольца 3 равные по диаметру цилиндрические -поверхности 19 и 20 цилиндра и крышки соответственно вл ютс жесткими направл ющими капсулы 5. .Торец 21 крышки и днище 22 цилиндра выполн ют роль разгрузочного поршн , воспринима давление рабочей среды напорното трубопровода и разгружа тем самым передний и задний обтекатели капсулы от статического давлени рабочей среды. Выравнивание давлений по обе стороны обтекателей происходит через имеющиес в них сквозные отверсти . Продольные пазы а, выполненные на цилиндрической части капсулы дл прохода ребер 4 корпуса, во всех положени х капсулы снаружи перекрыты полками 23 и 24 ребер благодар тому, что длина последних превышает полный ход капсулы.together with the ring 3 form a rigid monolithic system. The overhangs of the outer surface of the ring 3 are cylindrical cylindrical surfaces 19 and 20 and the cover, respectively, are rigid guides of the capsule 5. The end 21 of the cover and the bottom 22 of the cylinder act as a discharge piston, taking the pressure of the working medium to the pressure pipe and unloading the most front and rear capsule fairings from the static pressure of the working medium. The equalization of pressures on both sides of the fairings occurs through the through holes in them. The longitudinal grooves a, which are made on the cylindrical part of the capsule for the passage of the ribs 4 of the housing, in all positions of the capsule are outside covered with shelves 23 and 24 of the ribs due to the fact that the length of the latter exceeds the full travel of the capsule.
Регулирование расхода воды через ковшовую туроину осуществл етс перемещением капсулы.Controlling the flow of water through the bucket turboen is carried out by moving the capsule.
На закрытие капсула перемещаетс подачей рабочей жидкости под давлением через канал б в левую полость В гидропришада. Перемещение капсулы на открытие осуществл етс подачей рабочей жидкости под давлением через канал в в правую полость Г гидропривода .At the closure, the capsule is moved by supplying the working fluid under pressure through the channel b to the left cavity of the hydraulic device. Moving the capsule to the opening is carried out by supplying the working fluid under pressure through a channel into the right cavity G of the hydraulic drive.

Сопло ковшовой гидротурбины, содержащее размещенную в корпусе с наружным и внутренним кольцами капсулу, снабженную сервомотором, включающим цилиндр и крышку , и разгрузочный поршень отличающеес A bucket hydroturbine nozzle containing a capsule placed in a housing with outer and inner rings, equipped with a servomotor including a cylinder and a cap, and a discharge piston characterized by
5 тем, что, с целью улучшени геометрии нроточной части, иаправл ющ-а капсулу noBeipxность образована равными по диа.метру наружными поверхност м частей цилиндра сер0 вомотора, крышка которого служит разгрузочным поршнем, а внутреннее н наружное кольца корпуса соединены Т-образными ребрами с длиной полки последних, равной или большей длины полного хода капсулы.5 by the fact that, in order to improve the geometry of the flowing part, the guideway capsule is formed equal in diameter to the outer surfaces of the parts of the cylinder of the servo motor, the lid of which serves as a discharge piston, and the inner and outer rings of the housing are connected by T-shaped ribs the length of the shelf last, equal to or greater than the length of the full stroke of the capsule.
