Abstract

The technical result of the invention is an increase in the range of water shut-off and purification hardware for pipelines. The tap with a filter comprises a housing having a ball valve, a collared inlet duct and a collared outlet duct situated on the same axis on opposite sides of the housing, a filtration chamber disposed radially relative to the axis of the inlet and outlet ducts, a stopper, and a filter element in the form of a sleeve. The gap inside the housing between the inlet and outlet ducts is closed off by a dividing partition. The filtration chamber has an annular centring element with an inlet opening at the centre thereof, said centring element abutting one of the end portions of the filter element and passing along the dividing partition and part of the housing in the region of the inlet duct. The stopper is secured in the filtration chamber and is provided with an annular centring element which abuts the other end portion of the filter element. The centring elements and the filter element are situated on the same axis, which intersects the axis of the inlet and outlet ducts at a right angle. The ball valve is provided with a guide opening and is mounted in the housing between the dividing partition and the inlet duct in such a way that it can be rotated manually through a right angle.

Description

Filter tap

Technical field

The invention relates to the construction, and in particular to a crane with a filter used as shut-off and water treatment fittings installed in a pipeline of a cold or hot water supply network, a gas network, including a compressed air network for industrial purposes, into a pipeline performing any other technological function and transporting liquid or gas.

State of the art

Known crane with a filter containing a housing having inlet and outlet couplings located on the same axis on opposite sides, the first of which is made with an internal thread, and the second with an external thread located on an end sleeve fixed to the thread in the housing for a tightened seal installed in the ball valve housing, having for control a rod extending from the housing with a handle at the end (CN 2425696 Y, IPC B01D 25/22, 2001).

The ball valve is made with a direct through hole and, when rotated at a right angle, provides a channel overlap in the housing from the inlet coupling to the outlet coupling.

A sleeve nut is installed on the external thread of the output coupling pipe on the end sleeve, pressing an additional sleeve with an outer flange to its end, mating with the internal flange of the union nut, as well as with an external thread designed to connect the pipeline.

The additional sleeve, in turn, presses the filter element, made in the form of a glass with an outer flange along the edge, to which it interacts with the additional sleeve, towards the end of the end sleeve. The glass of the filter element is made with a cylindrical surface having a smaller diameter than the inner diameter of the additional sleeve, so that between its lateral outer surface and the inner surface an additional sleeve forms a gap, which allows the flowing fluid to pass both through the bottom of the glass of the filter element and through its side cylindrical walls.

In this known solution for cleaning the filter element, it is necessary to disassemble the pipeline, that is, twist the union nut, disconnect the additional sleeve associated with the pipeline and remove the filter element, inside which the sediment collects.

The filter element is installed in a direct uniform flow, which leads to a direct uniform pressure on the sediment particles accumulated in the filter element and exceeding the set parameters of the filter element in size, which can be pressed through it (slip), without providing the required level of filtration.

Known crane with a filter containing a housing having located on the same axis from opposite sides of the input and output coupling pipes with thread sections each for connecting to the pipeline, as well as a filter chamber located radially relative to the axis of the input and output coupling pipes, ball valve with rod and handle , the plug of the filter chamber and the filter element in the form of a sleeve (Vesta Trading Technical Catalog, 2009, p. 244).

The clearance of the housing cavity between the inlet and outlet coupling pipes is closed by a dividing bridge, and the ball valve is made with a direct through hole and is installed in the housing between the dividing bridge and the input coupling pipe with the possibility of rotation by a rod extending beyond the housing, on the outer end of which the handle is mounted, on right angle with overlapping in one of the channel positions from the input coupling pipe in the direction of the dividing jumper.

The filter chamber has an annular centering element coupled to one of the end parts of the filter element, passing through the jumper and part of the housing in the area of the ball valve, the medium through which flows when it is open into the filter element.

The plug is fixed in the filter chamber and is made with an annular centering element, which is mated to the second end part of the filter element. The annular centering elements of the filter chamber and plugs, as well as the filter element, are located on one axis intersecting the axis of inlet and outlet coupling pipes at an acute angle, the apex of which is oriented in the direction of the inlet coupling pipe.

The inner side walls of the filter chamber are located at a distance from the outer surface of the filter element to form an annular cavity located around the filter element that communicates with the cavity of the outlet coupling pipe, and a part of the side surface of the filter element is directly located in the cavity of the output coupling pipe.

The transported medium enters through the inlet coupling pipe, passes the ball valve and, slightly changing its direction, enters the cavity of the filter element, passing through which it enters the cavity of the outlet coupling pipe. The filter element is installed in the direction slightly deviated from the axis of the inlet coupling pipe at an acute angle, which leads to insignificant turbolization of the flow in the cavity of the filter element, which leads to a high directional pressure on the sediment particles that accumulate in the filter element and exceed the specified parameters of the filter element in size . As a result of the action of pressure, the particles trapped in the filter element can be forced through (slip) through the filter element, which does not provide the necessary level of filtration. SUMMARY OF THE INVENTION

The technical result consists in expanding the arsenal of means of shutoff and water treatment valves of pipelines, providing high the degree of purification in accordance with the parameters specified by the filter element by reducing the likelihood of an overflow of filtered particles through the filter element.

This technical result is achieved by a crane with a filter, which contains a housing having inlet and outlet couplings located on the same axis from opposite sides with thread portions each for connecting to the pipeline, as well as a filter chamber located radially relative to the axis of the inlet and outlet couplings, ball valve , a plug of the filter chamber and a filter element in the form of a sleeve.

The clearance of the housing cavity between the inlet and outlet coupling pipes is blocked by a dividing jumper, and the filter chamber has an annular centering element paired with one of the end parts of the filter element passing through the dividing jumper and a part of the housing in the area of the inlet coupling pipe, in the center of which the inlet is located. The plug is fixed in the filter chamber and is made with an annular centering element, which is mated to the second end part of the filter element. In this case, the annular centering elements of the filter chamber and plugs, as well as the filter element are located on one axis intersecting with the axis of location of the input and output coupling pipes at right angles.

The ball valve is made with a guide hole and is installed in the housing between the dividing jumper and the input coupling sleeve with the ability to manually rotate at a right angle to overlap the cavity of the input coupling pipe in one extreme position and to communicate with the filter element cavity through the filter chamber inlet at the other extreme position.

The inner side walls of the filter chamber are located at a distance from the outer surface of the filter element to form an annular cavity located around the filter element that communicates with the cavity of the outlet coupling pipe the outlet channel, and the lateral surfaces of the outlet channel are located at an acute angle to the axis of the inlet and outlet coupling pipes, the apex of which is directed in the direction from the inlet coupling pipe to the output coupling pipe.

The guide hole of the ball valve can be made in the form of communicating radial diametrical and perpendicular to it.

Due to the optimization of the movement of the filtered medium in the filter tap, filtering elements can be used as follows:

- from a pipe segment from a mesh of polymer or mineral fibers with a cell size in the range of 70 - 800 microns;

- from a piece of pipe from a mesh or in the form of a shell welded from a rectangular blank of a mesh from stainless steel wire with a mesh size in the range of 70 - 800 microns;

- from a pipe segment or in the form of a shell welded from a rectangular billet, stainless steel with a thickness of 0.15 - 0.5 mm with holes whose diameters lie in the range of 70 - 1000 microns;

- from a blank of woven or non-woven fabric made of polymer or mineral fibers located between two tubular blanks of a mesh of polymer fibers with a filtering capacity in the range of 50 - 100 microns;

- in the form of a bobbin wound from a polymer or mineral thread with a filtering ability in the range of 15-60 microns. The implementation of the invention

The possibility of implementing a technical solution is confirmed by a specific example of a filter with a crane, a longitudinal section of which is presented in figure 1. Figure 2 shows a cross section of a crane with a filter by a plane passing along the axis of the filter element.

The crane with a filter contains a housing 1 having a coupling located on the same axis from opposite sides of the input 2 and output 3 nozzles with sections 4 of internal thread each for connection to the pipeline (not shown in the drawings), as well as a filter chamber 5 located radially relative to the axis of the inlet 2 and outlet 3 of the coupling nozzles, a ball valve 6 with a rod 7 (Fig. 2) that extends beyond housing 1, and a handle 8 for manually turning the ball valve 6, the plug 9 of the filter chamber 5, as well as the filter element 10 in the form of a sleeve.

The clearance of the cavity of the housing 1 between the input 2 and output 3 of the coupling nozzles is blocked by a dividing jumper 1 1 (figure 1). The filter chamber 5 has an annular centering element 13 interfaced with one end part 12 of the filter element 5 and extending along the dividing jumper 1 1 and part of the housing 1 in the area of the inlet coupling pipe 2, in the center of which the inlet 14 is located.

The plug 9 is fixed in the filter chamber 5 and is made with an annular centering element 15, which is associated with the second end part 16 of the filter element 10.

The annular centering elements 13, 15 of the filter chamber 5 and the plug 9 are each made in the form of a groove with a cylindrical surface facing the axis, in which the filter element 10 is installed with end parts 12, 16. The bottom recess 17 is made along the axis of the centering element 15 in the plug 9. Ring the centering elements 13, 15 of the filter chamber 5 and the plug 9, as well as the filter element 10 are located on the same axis, intersecting with the axis of location of the input 2 and output 3 of the coupling nozzles at right angles.

The ball valve 6 is made with a guide hole 18 and is installed in the housing 1 between the dividing jumper 1 1 and the input coupling pipe 2 with the possibility of manual rotation by a right angle for overlapping in one extreme position of the cavity 19 of the input coupling pipe 2 and for its communication with the filter cavity 20 element 10 through the inlet 14 of the filter chamber 5 in another extreme position. To realize this possibility, the guide hole 18 of the ball valve 6 is made in the form of communicating diametrical 21 and radial 22 channels perpendicular to it. In the first mentioned extreme position, the ball valve is oriented by the radial channel 22 towards the dividing bridge 10, and in the second extreme position is oriented towards the inlet 14, while the diametrical channel 21 is open towards the cavity 19 of the inlet coupling pipe 2, as shown in FIG. one.

The inner side walls 23 of the filter chamber 5 are located at a distance from the outer surface 24 of the filter element 10 to form an annular cavity 25 located around it, communicating with the cavity 26 (Fig. 1) of the outlet sleeve 3 of the outlet channel 27. The side surfaces 28 of the outlet channel 27 are located at an acute angle to the axis of the input 2 and output 3 of the coupling nozzles, the top of which is facing in the direction from the input coupling pipe 2 to the output coupling pipe 3.

The filter element 10 can be performed with a filtering ability selected from the range of 15 - 10,000 microns.

As noted above, filter elements 10 made as follows can be used (in the drawings, manufacturing options for the filter element 10 are not shown).

The filter element can be made of a pipe segment of a mesh of polymer or mineral fibers with a mesh size in the range of 70 - 800 microns. Nylon, polyethylene can be used as polymer fibers, and glass fiber as mineral fibers.

The filter element can be made of a piece of pipe made of mesh or in the form of a shell welded from a rectangular blank of mesh, stainless steel wire with a mesh size in the range of 70 - 800 microns.

The filter element can be made of a pipe segment or in the form of a shell welded from a rectangular billet, stainless steel with a thickness of 0.15 - 0.5 mm with holes whose diameters lie in the range of 70 - 1000 microns.

The filter element can be made of a blank from a woven or non-woven fabric made of polymer or mineral fibers (polyester fiber, nylon, fiberglass) located between two tubular blanks from a mesh of polymer fibers (nylon, polyethylene) with a filtering capacity in the range of 50 - 100 microns .

The filter element can be made in the form of a bobbin wound from a polymer or mineral thread (nylon, fiberglass) with a filtering ability in the range of 15-60 microns.

The filtered medium enters the cavity of the inlet coupling pipe 2 and further, turbulizing when the direction of movement changes in the guide hole 18, through the inlet 14 enters the cavity 20 of the filter element 10. Penetrating through the permeable body of the filter element 10, the filtered medium enters the annular cavity 25 and, flowing along the lateral surfaces 28 of the outlet channel 27, enters the cavity 26 of the output coupling pipe 3. A tap with a filter made in accordance with the present invention is installed horizontally isontally and the filtered precipitate is collected inside the bottom recess 17 of the plug 9. To clean the filter element 10, the plug 9 of the filter chamber 5 is removed and washed from the sediment. If necessary, the filter element 10 is also removed and washed or replaced with a new one. For cleaning, the valve is closed, that is, the ball valve 6 is rotated by the value of the right angle to the position when the radial channel 22 is oriented towards the dividing bridge 10.

The example embodiment of the invention is not exhaustive. Other embodiments of the invention are possible, corresponding to the scope of patent claims. All parts of a crane with a filter made in accordance with the present invention are manufactured using known technologies from materials traditionally used for such products.
