Description

Изобретение относитс  к технологии наполнени  ртутью гермоампул термометров.This invention relates to a mercury filling technology for thermometer thermometers.

Процесс заключаетс  в разрежении ъ термоампуле воздуха путем удалени  носледнего (обезгаживание или вакуумирование) н в заполнении ртутью освобожденной от воздуха термоампулы. По существующей технологии термоамнулы наполн ютс  с разделением процессов обезгаживани  и автоклавировани  с применением ручного труда, при этом наполнение ртутью термоампул крупногабаритных термометров целиком выполн етс  вручную.The process consists in vacuuming the thermo-ampoule of air by removing the naslein (degassing or evacuating) n in filling the thermo-ampule released from air with mercury. According to the existing technology, thermoamnules are filled with separation of the processes of degassing and autoclaving using manual labor, while the mercury filling of the thermovials of large-size thermometers is performed manually.

Это ведет к малой производительности и контактированию рабочих с открытой ртутью.This leads to low productivity and contacting workers with open mercury.

Предлагаемый способ объедин ет процесс обезгаживани  и автоклавировани  в одной металлической камере с выведением ручек уиравлени  на общий щит и применением новой вакуумной и вакуумо-измерительной аппаратуры.The proposed method combines the process of degassing and autoclaving in the same metal chamber with the removal of levers on the common shield and the use of new vacuum and vacuum measuring equipment.

Такой способ устран ет непосредственный контакт рабочего со ртутью и повыщает производительность труда.Such a method eliminates the direct contact of the worker with mercury and increases labor productivity.

Термоампулы (см. чертеж), устапавливае.мые в специа.чьные корзины , прогреваютс  в электропечи 7 дл  удалени  адсорбированной стеклом влаги и вместе с корзинами постунают в камеру наполнени  2, герметично закрываемую.Thermo-ampoules (see drawing), installed in special baskets, are heated in electric furnace 7 to remove moisture adsorbed by glass and, together with baskets, are put into filling chamber 2, hermetically sealed.

Вентиль 3, соедин ющий камеру с вакуумной системой, открыт только при прохождении процесса обезгаживани  и закрываетс , полностью отсоедин   вакуумную систему от камеры, при процессе автоклавироваки . Масл ный вакуул1ный насос 4 через вентиль 5 создает предварительное разрежение в камере (форвакуум пор дка мм рт. ст.), необходимое дл  начала работы пароструйного ртутного агрегата 6 (примен етс  агрегат ВА-2-1), который, довод  остаточное давление в камере до мм рт. ст., производит удаление воздуха из резервуара и капилл ра термозаготовки.The valve 3 connecting the chamber to the vacuum system is open only during the degassing process and closes, completely disconnecting the vacuum system from the chamber during the autoclaving process. The oil vacuum pump 4, through valve 5, creates a preliminary vacuum in the chamber (forvacuum about 10 mm Hg), which is necessary for the start of operation of the steam-jet mercury unit 6 (the unit BA-2-1 is used), which the residual pressure in the chamber to mm Hg. Art., produces the removal of air from the reservoir and the capillary of heat preparation.

Создаваемый в системе вакуум контролируетс  магнитным вакуу.мметром 7 марки ВМБ-1.The vacuum created in the system is controlled by a magnetic vacuum gauge 7 of the mark VMB-1.

Ртуть дл  наполнени  термоампул очищаетс  дистилл цией (под вакуумом, создаваемым насосом 8) в электронагреваемом дистилл тоThe mercury for filling the thermovials is purified by distillation (under the vacuum created by the pump 8) in an electrically heated distillate
