Изобретение относитс к контроль но-измерительной технике, а именно к устройствам дл проверки на герметичность изделий, не имеющихсвободного внутреннего пространства, методом вакуумировани с применение течеискателей. The invention relates to the control of measuring equipment, namely, devices for testing the tightness of products that do not have a free internal space, by vacuuming with the use of leak detectors.
Известно устройство дл проверки изделий на герметичность, содержащее корпус и шток дл подачи изделий , снабженный полостью дл размещени изделий и св занный с приводо поступательного перемещени 1.A device for testing products for leak tightness is known, comprising a housing and a stem for supplying products, provided with a cavity for placing products and connected with a drive of translational movement 1.
Однако указанна камера не позвол ет вводить провер емое изделие в герметичном объеме в вакуумную камеру без нарушени ее герметичности , так как при движении штока с изделием в последней за счет неплотностей по диаметру штока происходит падение вакуума до величины, при котором течеискатель не фиксирует наличие пробного газа.However, this chamber does not allow the inspected product to be introduced in a hermetic volume into a vacuum chamber without breaking its tightness, since when the rod moves with the product in the latter, vacuum drops to a value at which the leak detector does not detect the presence of test gas due to leaks on the stem diameter. .
Целью изобретени вл етс повы шение надежности устройства дл проверки изделий на ге.Ехи етичность.The aim of the invention is to increase the reliability of the device for checking products on ge.
Это достигаетс тем, что устройство снабжаетс дополнительным штоком , установленным соосно штоку дл This is achieved by the fact that the device is supplied with an additional rod mounted coaxially with the rod for

На фиг.1 изображена камера, общий вид; на фиг.2 - узел I на фиг.1.Figure 1 shows the camera, a general view; figure 2 - node I in figure 1.
Вакуумна камера дл проверки изделий на герметичность имеет корпус 1, соединенный трубопроводом 2 с форвакуумным насосом 3, диффузионным насосом 4 и течеискателем 5 через The vacuum chamber for testing products for leak tightness has a housing 1 connected by a pipe 2 with a foreline pump 3, a diffusion pump 4 and a leak detector 5 through
0 вакуумные вентили 6-9. Внутри корпуса 1 размещены шток дл подачи изделий 10 и дополнитель ный шток 11, св занные с приводами поступательного перемещени 12 и 13. Шток при 0 vacuum valves 6-9. Inside the housing 1 there is a stem for supplying products 10 and an additional stem 11 connected with the translational displacement drives 12 and 13. The stem with
5 контактировании образуют герметичную полость 14, где размещаетс провер емое изделие 15. Герметичность полости 14 достигаетс торцовым уплотнением 16. В верхней полости штока 11 установлена пружина 17, 5, they form a sealed cavity 14, where the inspected product 15 is located. The tightness of the cavity 14 is reached by a mechanical seal 16. In the upper cavity of the rod 11 a spring 17 is installed,
0 при помощи которой шток 11 поджимаетс к штоку 10. Б местах ввода штоков в камеру установлены вакуумные уплотнени 18 и 19.0 by means of which the rod 11 presses against the rod 10. At the points where the rods are inserted into the chamber, vacuum seals 18 and 19 are installed.
