Abstract
Изобретение может быть использовано дл контрол герметичности замкнутых изделий . Цель изобретени - повышение точности путем учета негерметичности испытательной оснастки. Изделие помещают в замкнутую емкость, заполн ют ее контрольным газом и создают перепад давлений на стенкгх издели . После выдержки в течение заданного времени одновременно с определением скорости изменени давлени контрольного газа в емкости определ ют величину утечки контрольного газа из емкости в вакуумную камеру, а негерметичность издели рассчитывают как сумму измеренных потоков газа из издели в емкость и из емкости в вакуумную камеру. 1 ил.The invention can be used to control the tightness of closed products. The purpose of the invention is to improve accuracy by taking into account the leakage of test equipment. The product is placed in a closed container, filled with its control gas and creates a pressure differential on the wall of the product. After holding for a predetermined time simultaneously with determining the rate of change of pressure of the control gas in the tank, the amount of leakage of the test gas from the tank into the vacuum chamber is determined, and the product leakage is calculated as the sum of the measured gas flows from the product into the tank and from the tank into the vacuum chamber. 1 il.
Description
H3o6peTet ие относитс к испытательной технике и может быть использовано дл контрол герметичности замкнутых изделийH3o6peTet does not belong to the test technique and can be used to monitor the tightness of closed products.
Цель изобретени - повышение точности путем учета негерметичности испытательной оснасткиThe purpose of the invention is to improve the accuracy by taking into account the leakage test equipment
На чертеже схематично изображено устройство дл реализации способа контрол герметичности.The drawing schematically shows a device for implementing a method for monitoring tightness.
Устройство содержит вакуумную камеру 1 с мановакууметром 2, вакуумный насос 3 и течеискатель 4, соединенные с камерой 1 через вентили 5 и 6, и замкнутую емкость 7 с датчиком 8 давлени дл размещени контролируемого издели 9. Датчик 8 давлени соединен с выходным прибором 10.The device comprises a vacuum chamber 1 with a pressure sensor 2, a vacuum pump 3 and a leak detector 4 connected to chamber 1 through valves 5 and 6, and a closed container 7 with a pressure sensor 8 for accommodating the test article 9. The pressure sensor 8 is connected to an output device 10.
Способ осуществл етс следующим образом .The method is carried out as follows.
Заполненное газом изделие 9 помещают в замкнутую емкость 7, вакуумируют ее и заполн ют контрольным газом под давлением , создава на стенках издели 9 допустимый дл него перепад давлени , например равный максимальному перепад/ давлени The gas-filled product 9 is placed in a closed container 7, it is evacuated and filled with a test gas under pressure, creating a pressure differential for the product 9, for example, equal to the maximum pressure differential.
при его эксплуатации Емкость 7 с изделием 9 помещают в вакуумную камеру 1 и вакуумируют ее. Измер ют давление в емкости 7 датчиком 8 давлени . После выдержки в течение заданного времени одновременно измер ют течеискателем 4 величину потока контрольного газа из емкости 7 в вакуумную камеру 1, а датчиком 8 давлени измер ют давление в емкости 7. Суммарную негерметичность издели 9 определ ют как сумму потоков из издели 9 в емкость 7 и из емкости 7 в вакуумную камеру 1.during its operation, the container 7 with the product 9 is placed in a vacuum chamber 1 and vacuum it. The pressure in the tank 7 is measured by the pressure sensor 8. After holding for a predetermined time, the flow of the test gas from the tank 7 to the vacuum chamber 1 is measured simultaneously by the leak detector 4, and the pressure in the tank 7 is measured by the pressure sensor 8. The total leakage of the product 9 is determined as the sum of the flows from the product 9 to the tank 7 and from tank 7 to vacuum chamber 1.
Изобретение позвол ет повысить точность контрол суммарной негерметично- сти изделий.The invention makes it possible to increase the accuracy of controlling the total leakage of products.
