Description

II

Известлы способы контрол  герметичности , за1ключающиес  в том, что провер емое изделие заполн ют индикаторной жидкостью под ивбыточным давлением и фикси1руют места ее течей одиим из известных приемов, например визуально илп с помощью регистрирующей арпаратуфы.The methods of leakage control are known, which consist in filling the inspected product with indicator liquid under overpressure and fixing the places of its leaks by one of the known methods, for example, visually or through a recording apparatus.

Однако вы вление сквозных микронеплотиостей таким способом «енадежйо, так как в жидкости имеетс  раст1воревный газ.However, the detection of through micro-densities in this way is not reliable, as there is a common gas in the liquid.

Предлагаемый способ .контрол  герметичности отличаетс  от известных тем, что перед заполнением издели  индикаторной жидкостью его (вакуумируют, а индикаторную жидкость предва1рительно обеэгаживают.The proposed method of leakage control differs from the known ones in that before filling the product with indicator liquid (evacuate it, and the indicator liquid preliminarily evacuates.

По предлагаемому способу из индикаторной жидкости удал ют расгворенный в ней газ, а внутреннюю полость провер емогоAccording to the proposed method, the gas generated in it is removed from the indicator liquid, and the internal cavity of the test

издели  вакуумируют, после чего индикаторную жидкость под избыточным давлением полают в изделие и определ ют места течей одним из И31вестнь х приемов, например IBHзуально .the products are evacuated, after which the indicator liquid under pressure is poured into the product and the leak points are determined by one of the I31 well-known techniques, for example, IBH is normal.

Предмет изобретени Subject invention

Способ контрол  герметичности, заключающийс  в том, что п роввр емое изделие заполн ют индикаторной жид1костью под избыточным давлением и фиксируют места ее течей , отличающийс  тем, что, с целью повышени  надежности вы  влени  м-икронеплотностей , перед заполнением издели  индикаторной жидкостью его вакуумИруют, а индикаторную л идкость предварительно обезгаживают .The method of monitoring tightness, which consists in filling the product with indicator liquid under excess pressure and fixing its leak points, characterized in that, in order to increase the reliability of m-ircoremability, before filling the product with test liquid, vacuum indicator liquid is pre-degassed.
