The invention relates to filtration and can be used for the purification of hydrocarbon liquids in reversing systems, such as oil, fuel, special fluids in all sectors of the national economy.

The purpose of the invention is to increase the reliability of the filter, to improve the quality of cleaning and to expand the field of application by ensuring the use of filter elements with a dehydrating layer.

FIG. 1 shows a filter common to: - | d; in fig. 2 shows section A-A in FIG. one.

The filter consists of a cover 1, a bottom 2, a flow switch that includes a housing 3, check valves 4 and 5, a piston 6, a lower collector 7, an upper collector 8 with mounting holes for mounting racks 9, filter elements 10 of small diameters and together with them used water separating elements 11 (with the direction of filtration from the inside to the outside), a perforated center post 12 mounted on the check valve body 4, on which a large diameter filter element (not shown) of the inlet pipe 13 is installed, the output patra Bka 14, connecting pipes 15 connecting the cavities of the lower collector and the upper, formed by an annular groove 16 in the housing 1 and the grill 17, bypass pipes 18 and 19 with shut-off valves 20-23. The body of the flow switch has a cylindrical bore in which the piston 6 is moved, in the central part connected to the cavities of the check valves 4 and 5 and the inlet 13 and the outlet 14.

The end bores of the cylinder are closed by covers 24 and 25, which have seats for connecting bypass lines 18 and 19.

Drainage grooves 26 are made on the grate 17 of the upper collector 8 under the water separating element 11, and in the area of the grooves in the collector 8 and the housing 3 there are vertical channels 27 for draining the water into the cavity of the bottom 2, on which is installed a stopper 28 for draining water and CLEANING contamination.

The unified filter works as follows.

Depending on the filter element chosen, the check valves 4 and 5 and the by-pass valves 20-23 are installed in the working position.

When fluid is supplied to one of the pipes 14 or 15 under pressure, the piston moves from one extreme position to the other (if necessary) by the force of pressure of the filtered fluid. The piston connects the inlet and outlet nozzles through the filter elements and check valves 4 and 5 and provides the direction of movement of the fluid corresponding to each type of filter element.

Filtration with water separation occurs as follows. The liquid from the pipe 14 through the check valve 5 enters the cavity of the lower manifold 7, then through the connecting pipes 15 into the cavity of the upper collector 8, from there along the racks 9 through filter elements 10 And; water separating elements 11 into the cavity of the lid 1, then through the check valve 4 into the nozzle 13. When passing through the water separating element 11, water separates on the water-repellent layer, which flows down the drainage layer, collects in the annular grooves 26 and in vertical

branch duct 27 flows into the cavity of the bottom 2, from where it is periodically drained through the drain plug 28.

The setting and mode of operation depending on the filter element used are described in the table.

The use of the invention allows the use of a filter design with various filter elements: TF-2M filters, FS-BO with water separation, FTB-60, FGN-60; increase the reliability of the filter in reversible piping systems by connecting the injection and consumption lines using one filter instead of two without a flow switch in these systems.
