Description
Изобретение относитс к испытагельной технике, в частности к контролю герметичности изделий.The invention relates to a testing technique, in particular to the control of the tightness of products.
Известен способ контрол герме- . тичности изделий, заключающийс в том, что помещают изделие в герметичную оболочку, заполн ют изделие газом до заданного давлени , выдерживают изделие заданное врем и о герметичности издели суд т по изменению давлени в оболочке П .A known method of control herme-. products, consisting in placing the product in an airtight casing, filling the product with gas to a predetermined pressure, maintaining the product for a specified time and judging the tightness of the product is judged by the pressure change in the casing II.
Недостатком известного способа вл етс низкое качество контрол бумажных фильтрэлементов, так как ВЕЗдержка заданное врем издели под давлением приводит к изменению давлени в оболочке за счет проникновени газа через боковую поверхность фильтра.A disadvantage of the known method is the low quality of control of paper filter elements, since BEHORSE holding a predetermined time of the product under pressure leads to a change in pressure in the casing due to the penetration of gas through the side surface of the filter.
Цель изобретени - повышение качества при контроле изделий в виде бумажных фильтрэлементов.The purpose of the invention is to improve the quality in the control of products in the form of paper filter elements.
Указанна цель достигаетс тем, что согласно способу контрол герметичности изделий, помещают изделие в герметичную оболочку и о герметичности изделий суд т по изменению давлени в оболочке, при контроле изделий в виде бумажных фильтрэлемевтов , последний продувают струей сжатого воздуха, а о герметичности его суд т по падению давлени в оболочке в результате эжекции воздуха. This goal is achieved by the fact that, according to the method of monitoring the tightness of products, the product is placed in an airtight enclosure and the integrity of products is judged by the pressure change in the envelope, while controlling products in the form of paper filter filter elements, the latter is flushed with compressed air, and its integrity is judged by pressure drop in the shell as a result of the ejection of air.
На чертеже представлена схема устройства дл реализации предлагаемого способа.The drawing shows a diagram of the device for implementing the proposed method.
Устройство содержит патрубок 1, герметично прижатый к крышке 2 фильтрэлемента , и герметичную оболочку 3. The device contains a pipe 1, hermetically pressed to the cover 2 of the filter element, and a sealed casing 3.
10 Контроль издели в основном св зан с негерметичностью клеевого соединени боковушек с корпусом фильтрэлемента и дефектностью шторок 4.10 The control of the product is mainly due to the leak-tightness of the adhesive bonding of the sides to the filter element body and the defectiveness of the shutters 4.
Способ осуществл етс следующим The method is as follows.
15 образом.15 way.
Через патрубок 1 осуществл ют продувку фильтра сжатым воздухом. Фильтрэлемент помещают в герметичную оболочку 3. При негерметичности изде20 ли в воздушной полости, образованной изделием и оболочкой 3, за счет эжекции воздуха возникает падение давлени , которое фиксируетс манометром («е показан). По показани м Through the pipe 1, the filter is purged with compressed air. The filter element is placed in an airtight casing 3. When leakage is produced, an air pressure drop occurs in the air cavity formed by the product and casing 3, due to the ejection of air, which is fixed by a pressure gauge (e shown). By readings
25 манометра суд т о качестве издели .25 gauges judge product quality.
При отсутствии дефектов издели поток сжатого воздуха не вызывает падени давлени в воздушной полости.In the absence of product defects, the stream of compressed air does not cause a drop in pressure in the air cavity.
Способ обеспечивает высокое каче30 ство контрол и отличаетс надежноетью при невысокой стойкости иэгЬтовлеми оборудовани дл его реализации .The method provides high quality control and is reliable with low durability and the equipment necessary for its implementation.
