Description

В таком выполнении затвор обеспечивает свободный доступ к силовым механизмам, исключает вли ние условий вакуума на работоспособность затвора (особенно трущихс  пар), улучшает смазку. Силовой механизм, будучи вне вакуумной полости, не  вл етс  дополнительным источником газовыделени . Относительно малый ход домкратов позвол ет повысить продолжительность работы сильфонов и провести широкую унификацию узлов домкрата, поворотного механизма,электропривода и др.In such an embodiment, the valve provides free access to the power mechanisms, eliminates the influence of vacuum conditions on the performance of the valve (especially rubbing steam), and improves lubrication. The force mechanism, being outside the vacuum cavity, is not an additional source of gas evolution. The relatively slow speed of the jacks makes it possible to increase the duration of the bellows operation and to carry out a wide unification of the jack units, the turning mechanism, the electric drive, etc.

Форм у л а изо б р е т е л и  Formula isoboble

Шиберный затвор, в корпусе которого установлен запорный орган, снабженный домкратами и св занный с приводом через силовой и поворотный механизмы, размеш,енные вне вакуумной полости, отличающийс  тем, что, с целью повышени  надежности, силовой механизм выполнен в виде составной втулки, снабженной секторными клинь ми и установленной на штуцере корпуса.The slider gate, in the case of which a shut-off organ is installed, equipped with jacks and connected to the drive through power and turning mechanisms, placed outside the vacuum cavity, characterized in that, in order to increase reliability, the power mechanism is designed as a composite sleeve equipped with sector wedge mi and mounted on the housing case.
