Description
Изобретение относитс к испытани м на герметичность полых изделий, опрессованных повиненным давлением контрольного газа. This invention relates to leaktightness tests of hollow articles that have been pressed with a guided pressure of a test gas.
Наиболее близким к изобретению вл етс устройство дл испытани полых изделий на герметичность, содерж&цее камеру дл размещени издели , св занный с ней регистратор утечки, источник давлени контрольного газа в изделии и узел герметизации с уплотнительными элементами дл издели и камеры, при этом узел герметизации выполнен в виде устанавливаемого На изделии до подачи в него давлени заглушающего приспособлени 1.Closest to the invention is a device for testing hollow articles for tightness, contains & a chamber for placing the product, a leakage recorder associated with it, a source of control gas pressure in the product and a sealing assembly with sealing elements for the product and the chamber, while the sealing assembly made as installed on the product prior to supplying pressure from the damping device 1.
Недостатком устройства вл етс невысока надежность испытаний, обуслокпенна по влением дополнительных дефектов в издели х, особенно в тонкостенных , возникающих в результате усилий прижима на уплотнительные элементы при его герметизации, а износом уплотнительных элементов , воэинкаюсф м при создании усилий прижима выше необходимых дл ,заданного испытательного давлени . Цель изобретени - повышение надежности испытаний.The drawback of the device is the low reliability of the tests, due to the appearance of additional defects in the products, especially thin-walled ones, resulting from the clamping forces on the sealing elements when it is sealed, and the wear of the sealing elements, when creating the clamping forces higher than necessary for the test pressure. The purpose of the invention is to increase the reliability of the tests.
Цель достигаетс тем, что устройство дл испытани полых изделий на герметичность, содержащее кайзеру дл размещени издели , св занный с ней регистратор утечки, источник давлени контрольного газа в изделии и узел герметизации с уплотнительными элементами дл издели и камеры, снабжено регул тором давлени , выход The goal is achieved by the fact that a device for testing hollow articles for leak tightness, containing a Kaiser for placing a product, a leakage recorder associated with it, a source of control gas pressure in the product and a sealing assembly with sealing elements for the product and the chamber, is equipped with a pressure regulator
10 которого св зан с источником давлени , узел герметизации выполнен в виде пневмоцилиндра со св занными штоком двум поршн ми, один из которых служит дл прижима уплотнитель15 ных элементов, а вход регул тора давлени св зан с бесштоковой полостью пневмоцилиндра.10 of which is connected with a pressure source, the sealing unit is designed in the form of a pneumatic cylinder with two pistons connected by a rod, one of which serves to clamp the sealing elements, and the input of the pressure regulator is connected with the rodless cavity of the pneumatic cylinder.
На 1ертеже представлена схема устройства дл испытани полых из20 делий на герметичность.The layout of the device for testing hollow materials for tightness is presented on the sheet.
Устройство содержит камеру 1 дл размещени издели 2, источник 3 давлени контрольного газа, св занный с выходом регул тора 4 давлени , The device comprises a chamber 1 for accommodating the product 2, a source 3 of a pressure of the control gas associated with the output of the pressure regulator 4,
25 вход которого св зан с бесштоковой полостью 5 пневмоцилиндра б с поршн ми 7 и 8 и штоком 9.25 whose inlet is connected to the rodless cavity 5 of the pneumatic cylinder b with pistons 7 and 8 and the rod 9.
Герметизаци камеры 1 осуществл етс уплотнительными элементами 10, The sealing of chamber 1 is carried out by sealing elements 10,
