Description
Предметом изобретени во1 етс устройство дл уплотнени вала, проход щего через стенку вакуумной камеры, посредством подводимых в зазор жидкости или газа под давлением. .The invention relates to a device for sealing a shaft passing through the wall of a vacuum chamber by means of a pressurized fluid or gas entering the gap. .
Описываемое устройство по сравнению с известными устройствами того же назначени обеспечивает более надежное уплотнеине, устран возможность попадани уплот )1 ющей среды внутрь какгеры.The described device, in comparison with the known devices of the same designation, provides a more reliable sealing, eliminating the possibility of the sealing medium getting inside as gages.
Дл этой цели в устройстве применено окружающее вал кольцеобразное , из которого направленна в сторону от вакуумной камеры стру жидкост ИЛИ газа перекрывает зазор валом и краем отверсти в стенке камеры.For this purpose, an annular shaft surrounding the shaft is applied in the device, from which the liquid OR gas jets away from the vacuum chamber closes the gap with the shaft and the edge of the hole in the chamber wall.
На чертеже изображена схема устройства.The drawing shows a diagram of the device.
Вращающийс на большой скорости вал / проходит через стенку 2 вакуумной камеры, образу зазор 3.The shaft rotating at high speed / passes through the wall 2 of the vacuum chamber, forming a gap 3.
Вокруг вала расположены кольдеобразиое сопло 4 и сопло 5.Around the shaft are colderbased nozzle 4 and nozzle 5.
Жидкость (или газ) подаетс под. давлением в полости 6 и 7, проходит сопла 4 и в виде струи, направленной в сторону от вакуумной камеры, входит в полость 6, плотно перекрыва при этом з зор 3.Liquid (or gas) is supplied under. pressure in the cavity 6 and 7, passes the nozzle 4 and in the form of a jet directed away from the vacuum chamber, enters the cavity 6, tightly blocking the gap 3.
Предмет изобретени Subject invention
Устройство дл уплотнени вала, проход щего -.ероз стенку вакуумной камеры, посредством подводимых в зазор жидкости или газа под давлением, о т л ;i ч а ю щ е е с тем, что, с целью предотвращени возможности попадй1И1Я уплотн ющих жидкости или газа внутрь камеры, применено окружающее вал кольцеобразное сопло, из которого направленна в сторону от вакуумной камеры стру л идкости или газа перекрывает зазор между валом и краем отверсти в стенке камеры.A device for sealing the shaft passing through the wall of the vacuum chamber by means of a liquid or gas fed into the gap under pressure, so that, in order to prevent the sealing liquid or gas from entering An annular nozzle surrounding the shaft is applied inside the chamber, from which a jet of liquid or gas is directed away from the vacuum chamber and closes the gap between the shaft and the edge of the hole in the chamber wall.
