Description

Цель изобретени  заключаетс  в создании технологического процесса, позвол ющего применить дл  ва; уумной обработки газонаполненных электровакуумных приборов, имеющих малые рабочие давлени  газа (пор дка дес тых долей мм рт. ст.), высокопроизводительные автоматы откачки вакуумных ламп.The purpose of the invention is to create a process that can be applied to you; intelligent processing of gas-filled electrovacuum devices with low operating gas pressures (on the order of tenths of a millimeter of mercury), high-performance automatic machines for pumping out vacuum tubes.

Сущность изобретени  состоит в том, что наполнение приборов газом производитс  после отпайки их путем вскрыти  стекл нной ампулы, предварительно наполненной определенной Порцией инертного газа.The essence of the invention is that the devices are filled with gas after they have been desoldered by opening the glass ampoule, which is pre-filled with a certain portion of inert gas.

Ам ула изготавливаетс  из стекла на автомате дл  изготовлени  миниатюрных колб.Amula is made of glass on a miniature flask machine.

На откачном посту или автомате с дозирующим устройством ампулы откачиваютс  и прогреваютс  до температуры 200-250° в течение 2-3 минут. После остывани  ампулы наполн ютс  газом до определенного давлени , рассчитываемого из соотношени At the pumping post or automatic dispenser with a dosing device, the ampoules are pumped out and heated to a temperature of 200-250 ° for 2-3 minutes. After cooling, the ampoules are filled with gas to a certain pressure, calculated from the ratio

где:Where:

PV P,V,,PV P, V ,,

Р - рабочее давление в приборе;Р - working pressure in the device;

V - объем прибора;V is the volume of the device;

Я - давление газа в ампуле;I is the gas pressure in the ampoule;

V - объем ампулы, и опаиваютс .V is the volume of the ampoule, and is soldered.

с газом помещаетс  в никелевый цилиндр и с помощью держател  закрепл етс  на ар.матуре прибора. Смонтированный прибор завариваетс  и подвергаетс  вакуумной обработке. The gas is placed in a nickel cylinder and fixed to the armature of the instrument with the help of a holder. The mounted device is sealed and vacuum processed.

Вакуумна  обработка производитс  на автомате откачки вакуумных ламп. После отпайки прибора распыл етс  газопоглотитель. Затем токами высокой частоты никелевый цилиндр с ампулой разогреваетс  до температуры 1050-1100°. При этом стекло ампулы разм гчаетс , давление в ампуле резко повышаетс  и газ вырываетс  из ампулы. Момент вскрыти  ампулы четко виден по свечению газа.Vacuum processing is performed on a vacuum tube pumping machine. After the instrument has been tipped off, the getter is sprayed. Then, by high-frequency currents, the nickel cylinder with an ampoule is heated to a temperature of 1050-1100 °. At the same time, the glass of the ampoule is softened, the pressure in the ampoule rises sharply and the gas is pulled out of the ampoule. The moment to open the ampoule is clearly visible by the glow of the gas.

Точность наполнени  приборов газом вышеописанным способом составл ет 5-7% от номинала.The accuracy of filling the devices with gas as described above is 5-7% of the nominal value.

Предмет и з о б. р е т е н и  Subject and s about b. rete n i

Способ наполнени  газом электровакуумных приборов, имеющих малое рабочее давление (дес тые доли мм рт. ст.), отличающийс  тем, что, с целью автоматизации вакуумной обработки приборов, газ выпускают в откачанный и орпа нный прибор из предварительно вмонтированной в него стекл нной ампулы , содержащей определенное количество газа.The method of filling gas with vacuum devices having a small working pressure (tenths of a mm of mercury), characterized in that, in order to automate the vacuum processing of the devices, the gas is released into a pumped out device from a glass ampoule pre-installed in it containing a certain amount of gas.
