(54) УСТАНОВКА ДЛЯ ИСПЫТАНИЯ ИЗДЕЛИЙ НА ГЕРМЕТИЧНОСТЬ(54) INSTALLATION FOR TESTING PRODUCTS FOR TIGHTNESS
10 с подвижной частью 11, элемента 12 ее фиксации и двух идентичных вакуумных присосок 13 и 14 с герметизирующими .элементами 15 дл установки между ними испытуемого издели 8, одна из которых установлена на подвижной части 11 штатива 10, а друга - симметрично ей на основании 9 камеры 1, а внутренние полос;ти 16 присосок сообщены с вентил ми 3 и 4 вакуумировани .10 with a movable part 11, its fixation element 12 and two identical suction cups 13 and 14 with sealing elements 15 for placing test product 8 between them, one of which is mounted on the movable part 11 of the tripod 10 and the other symmetrically to it on the base 9 chambers 1, and internal strips; these 16 suction cups are connected to evacuation valves 3 and 4.
Установка работает следующим образом .The installation works as follows.
Испытуемое изделие 8 устанавливаетс на герметизирующий элемент 15 вакуумной присоски 14, закрепленной нт основании 9 камеры 1, а вакуумную присоску.13, закрепленную на подвижной части 11 штатива 10, принадлежащего устройству 7, опускают на изделие 8 таким образом, чтобы ее герметизирующий элемент 15 был установлен против герметизирующего элемента 15 присоски 14 и фиксируют ее положение элементом 12.The test article 8 is mounted on the sealing element 15 of the vacuum sucker 14, fixed on the base 9 of the chamber 1, and the vacuum sucker 13 fixed on the movable part 11 of the tripod 10 belonging to the device 7 is lowered onto the product 8 so that its sealing element 15 is installed against the sealing element 15 of the suction cup 14 and fix its position by the element 12.
Производ т герметизацию камеры 1 и откачку воздуха из нее через вентиль 2, соединенный с системой вакуумированв .The chamber 1 is sealed and air is pumped out of it through the valve 2 connected to the vacuum system.
При необходимости откачивают воздух из полостей 16 присосок 13 и 14, сообщенных через вентили 3 и 4 системой вакуумировани .If necessary, air is pumped out of the cavities 16 of the suction cups 13 and 14 communicated through the valves 3 and 4 by the vacuum system.
Затем заполн ют камеру 1 контрольным газом при помощи системы подачи контрольного газа через вентиль 5, воздава в keUviepe 1 испытательное давление более высокое, чем в испытуемом изделии 8 и выдерживают режим испытани заданное врем .Then the chamber 1 is filled with the test gas using the system for supplying the test gas through the valve 5, returning the test pressure to keUviepe 1 higher than in the test article 8 and withstand the test mode for a specified time.
Контроль величины давлени в камере 1 осуществл ют при помощи мановакууметра 6.The control of the pressure in chamber 1 is carried out with the aid of a manovacimeter 6.
Использование предлагаемой установки позвол ет значительно повыситьThe use of the proposed installation can significantly increase
производительность испытаний путем увеличени давлени контрольного газа в камере, а следовательно, и скорости проникновени его в испытуемое изделие через микродефекты замыкающего шва, за счет изолировани от воздействи внешнего избыточного давлени заведомо герметичных противоположных частей тонкостенной оболочки издели .test performance by increasing the pressure of the control gas in the chamber, and, consequently, the speed of its penetration into the product under test through microdefects of the closing seam, due to the isolation of the obviously hermetic opposite parts of the thin-walled shell of the product from external overpressure.
