Изобретение относитс .к области фильтровани , а именно к фильтрам дл очистки жидкостей и газов от твердых механических затр Знений.The invention relates to the field of filtration, namely to filters for the purification of liquids and gases from solid mechanical effects.

По ocHOBiHOMy авт. св. № 502642 известен патронный фильтр, состо щий из коммуникационной головки, в котарой |размещен входной клапа-н с установленным «а нем си льфоном с onqp HbiM фланцем и вььходаной клапан. Коммуникационна головка соедин етс с корпусом (стаканом) фильтра, в котором размещен фильтрующий элемент ,1.By ocHOBiHOMy auth. St. No. 502642 a cartridge filter is known, consisting of a communication head, in which | an inlet valve is placed with an installed air filter with an onqp HbiM flange and an open valve. The communication head is connected to the filter housing (cup) in which the filter element 1 is placed.

Известный фильтр обладает следующими недостатками:The known filter has the following disadvantages:

недостаточной надежностью в .работе, обусловленлой возмож«остью разгерметизации входного клапа-на в месте уплотнени с буртиком фильтроэлемента при воздействии вибрационных и ударных нагрузок;insufficient reliability in operation, due to the possibility of the depressurization of the inlet valve at the sealing location with the filter element shoulder under the influence of vibration and shock loads;

повышенными гидравлическ ими потер ми, обусловленными попаданием потока, среды на гофр-крованиую поверхность сильфона;increased hydraulic losses due to the flow of the medium on the corrugation of the bellows;

снижением долговечности, обусловленной ИЗНОСОМ торцового уплотнени входного клапана и выходом из ст.ро сильфона. reduced durability due to the wear of the mechanical seal of the inlet valve and the outlet from the stro of the bellows.

Целью изобретени . вл етс повышение надежности и долговечности патронного фильтра , .снижение его гидравлических потерь.The purpose of the invention. is to increase the reliability and durability of the cartridge filter, reducing its hydraulic losses.

Это дocт игaeтo тем, что фильтр снабжен защитными гильзами, одна из которых установлена снаружи сильфона и жестко соединена с ОД1НИ1М из его торцО|В, а друга уста.новлена внутри сильфона и выполнена заодно с п той входного клалана, снабженного иаправл ющ .ими выступами.This is due to the fact that the filter is equipped with protective sleeves, one of which is installed outside the bellows and is rigidly connected to OD1NIIM from its front | B, and the other is installed inside the bellows and is made together with a fifth inlet clalan equipped with a guide. .

На фиг. 1 изображен натронный фильтр, общий вид; (На фиг. 2 - разрез А-А на фиг.1.FIG. 1 shows a soda filter, general view; (In Fig. 2 - section aa in Fig.1.

Патронный фильт.р состоит из коммуникационной головки, включающей .в себ корпус 1 с седлом 2, крышку 3, крестов.и-ну 4 с отверсти ми 5, ВХОД1НОЙ клапан 6, состо щий из наружной защитной тильзы 7, жестко соединенной с сильфоном 8, который другим кон.цом жестко соединен с п той 9, выполненной с напра1вл ющ .ими выступами 10, тор1цовым уплотнителем // « внутрен1ней цилиндрической защитной гЕльзой 12, выпускной клалан 13, расположенный в продольном отверстии п ты впускного клапана и подпружиненный пружиной 14.Cartridge filter.p consists of a communication head including body 1 with seat 2, cover 3, crosses and 4 with holes 5, INPUT valve 4, consisting of an external protective sleeve 7, rigidly connected to the bellows 8 The other end is rigidly connected with fifth 9, which is made with directional protrusions 10, with a top seal // “internal cylindrical protective sleeve 12, exhaust valve 13, located in the longitudinal opening of the inlet valve and spring-loaded spring 14.

Коммуникационна головка при помощи накидной гайки 15 соедин етс со стаканам 16, в .котором помещен фильтроэлемент 17, имеющий окна 18 дл прохода рабочей среды. В коммуникациоБной rOvioBKe установлены входной и ВЫХОД1Н.ОЙ шт1уцврьт 19 и 20.The communication head is connected to the glasses 16 by means of a cap nut 15, in which the filter element 17 is placed, which has windows 18 for the passage of the working medium. In the communication rOvioBKe, the input and output OUT of the unit 19 and 20 are installed.

Работает патрон.ный фильтр следующим образом.Powered cartridge filter as follows.

Claims

The contaminated working medium through the inlet fitting 19 enters the body /, washes the input valve 6 and through the annular gap between the saddle and the fifth: the inlet valve, divided by equalizing tabs into several parts, enters the internal cavity of the cup 16, then through the porous surface of the filter element 17, oqEiueHHaH from mechanical impurities, enters the internal CAVITY of the communication head and through the outlet fitting 20 -, into the system. When the surface of the filtering element becomes clogged, the pressure of the working medium in the INPUT cavity of the communication head increases, and the pressure differential between the input and output cavities of the communication head increases and reaches a predetermined value compresses the bellows, opens 1c: the inlet valve the element enters the system, which prevents the filter from being completely filled and (the possibility of a1va | p1ni. If the filtering element has to be replaced or regenerated, the captive turn is turned off JK 15 And removing the cup 16 with the filter element 17. | Vp.uaynoj valve 6 under the action of the expansion valve 8 is lowered down and sits conical surface on the edge of the saddle 2, sealing the inlet cavity of the filter from the environment. also moves downwards and sits with its conical surface on the edge of the opening of the inlet valve, sealing the outlet cavity from the environment. Thus, bree replacing the filter element prevents the medium from leaking out of the system. When the "new filter element" is installed, the inlet and exhaust valves, resting against its end, are set to their original position. The use of the invention will improve the reliability and durability of the filter, reduce hydraulic losses, as well as expand its area of application in terms of vibration and shock loads. Invention Cartridge filter according to the author. St. No. 502642, characterized in that, in order to increase Reliability, filter durability and reduce hydraulic losses, the filter is provided with protective sleeves, one of which is installed bellows and rigidly connected to one of its ends, and the other is installed inside the sleeve and is integral with one FIFTH inlet valve with guide lugs.
