Изобретение относитс к испытательным стендам, содержащим барокамеры.This invention relates to test benches containing pressure chambers.
Известны слютровые окна барокамер с металлическими шторками, открываемыми кратковременно дл наблюдени за объекта: ми, размещенными в барокамере. При таких окнах не исключаетс конденсаци паров, имеющихс в барокамерах, на внутренней поверхности смотрового стекла, что затрудн ет наблюдени из-за недостаточной оптической прозрачности стекла.Sluter windows of pressure chambers with metal shutters that are opened briefly to monitor the object are located: mi located in the pressure chamber. With such windows, condensation of vapors present in the pressure chambers on the inner surface of the sight glass is not excluded, which makes it difficult to observe due to insufficient optical transparency of the glass.
Изобретение позвол ет устранить указанный недостаток благодар тому, что на внутренней поверхности смотрового стекла закреплен электрический нагреватель в виде оптически прозрачной и электрически провод щей пленки, например, из серебра, имеющей электрические токоподводы.The invention eliminates this drawback due to the fact that an electric heater in the form of an optically transparent and electrically conductive film, such as silver, having electrical current leads, is fixed on the inner surface of the sight glass.
Предложенное смотровое окно показано на чертеже.The proposed viewing window is shown in the drawing.
Смотровое окно состоит из плоскоиарал .лельного стекла / и крепежного фланца 2, герметично состыкованного с ответным фланцем 3 барокамеры 4. Снаружи стекло закрыто защитным стеклом 5. На внутреннюю поверхность стекла нанесена оптически прозрачна и электрически провод ща лленка 6, нмеюща электрические токоподводы 7. Пленка 6 может быть выполнена из серебра.The viewing window consists of flat aerial glass / and a mounting flange 2, hermetically sealed to the counter flange 3 of the pressure chamber 4. Outside the glass is covered with protective glass 5. Optically transparent and electrically conductive lens 6 is applied to the inner surface of the glass 7. Film 6 can be made of silver.
По токоподводам 7 подают электрическое напр жение дл нагрева пленки 6 до температуры , превыщающей температуру конденсации паров в барокамере 4. Например, в случае нал .ичи в паров цези .при давлении пор дка 10 мм рт. ст. пленку 6 нагревают до температуры выше 150° С. Благодар этому исключаетс конденсаци паров на внутренней поверхности.The current leads 7 are supplied with an electrical voltage to heat the film 6 to a temperature higher than the vapor condensation temperature in the pressure chamber 4. For example, in the case of cash in cesium vapor, at a pressure of about 10 mm Hg. Art. the film 6 is heated to a temperature above 150 ° C. Due to this, vapor condensation on the inner surface is avoided.
Предмет изобретени Subject invention
Смотровое окно преимущественно вакуумных камер, содержащее плоскопараллелькое стекло и 1креиежнь й фланец, отличающеес тем, что, с целью стабилизации оптической прозрачности стекла, его внутренн поверхность снабжена электрическим нагревателем в виде оптически прозрачной и электрически провод щей пленки, например пленки серебра, имеющей электрические токоподводы.A viewing window of predominantly vacuum chambers containing plane-parallel glass and 1 co-flange, characterized in that, in order to stabilize the optical transparency of the glass, its internal surface is provided with an electric heater in the form of an optically transparent and electrically conductive film, such as a silver film having electrical current leads.
