Description

Изобретение относитс  к области фильт ровани , а именно к патронным фильтрам, устанавливаемым преимущественно на всасывающей стороне насоса, и может быть применено в новых дл  обработки текучих сред под давлением в различных област х техники Известен фильтр, содержащий концентрически расположенньхе фильтровальные элемен ты с общей крыщкой и отверстием на противоположном конце дл  отвода фильтрата J Недостатком известного фильтра  вл етс  то, что над крышкой фильтра накапливаетс  газ, который ухудшает фильтрацию, а также способствует развитию навигации в насосе. С целью повыщени  эффективности фильтровани  фильтр снабжен газоотводной трубкой с отверстием на одном конце. Один конец трубки прикреплен к крышке, а другой выполнен коническим и свободно размещен в отверстии дл  отвода фильтрата. Целесообразно газоотводную трубку выпо нить изогнутой. На чертеже показана конструкци  фильт ра, общий вид. Фильтр состоит из внешнего фильтрующего элемента 1, установленного между крыи1ками 2 и 3, и внутреннего фильтрующего элемента 4, установленного конивнтринаскл внещнему фильтрующему элементу на крышке 2. С другой стороны внутренний фильтрующий элемент имеет крышку 5, на которой установлен перепускной клапан 6. Концентрически внутреннему фильп руюшему элементу 4 установлен сетчатый фильтрующий элемент 7, Между внешним 1 и внутренним 4 фильтрующими элементами образовано кольцевое пространство 8, ограниченное в верхней части крышкой 2, а в нижней соединенное с оч верстием 9 дл  отвода фильтрата. В кольцевом пространстве 8 установлена газоотводна  трубка 10, котора  одним концом закреплена с уплотнением в. крышке 2, а другим , свободным концом 11, выведена в середину отверсти  9 дл  отвода фильтрата. Изогнута  газоотводна  трубка около крышки 2 выполнена с отверстием 12 дл  забора газа, а свободный ее конец 11с отверстием 13 выполнен коническим.The invention relates to the field of filtration, namely to cartridge filters, installed mainly on the suction side of the pump, and can be used in new for treating fluids under pressure in various fields of technology. A filter is known which contains concentrically arranged filter elements with a common lid and a hole at the opposite end to remove the filtrate J A disadvantage of the known filter is that gas accumulates above the filter cover, which impairs filtration and also contributes to em development of navigation in the pump. In order to increase the filtration efficiency, the filter is provided with a venting tube with a hole at one end. One end of the tube is attached to the lid, and the other is tapered and freely placed in the hole for draining the filtrate. It is advisable to vent the tube bent out. The drawing shows the construction of the filter, a general view. The filter consists of an external filter element 1 installed between the rails 2 and 3, and an internal filter element 4 installed at the external filter element on the lid 2. On the other hand, the internal filter element has a lid 5 on which the overflow valve 6 is mounted. The main element 4 is equipped with a mesh filter element 7. Between the outer 1 and inner 4 filter elements, an annular space 8 is formed, bounded by a cover 2 in the upper part, and It is connected to Pc version 9 for removal of the filtrate. In the annular space 8 there is a vent pipe 10, which is fixed at one end with a seal c. the cover 2, and the other, the free end 11, displayed in the middle of the hole 9 for removal of the filtrate. The bent flue gas pipe near the lid 2 is made with a gas inlet 12, and its free end 11c is conical with aperture 13.
