The invention relates to high-efficiency plumbing repair and maintenance tools, equipment for water supply systems of residential and other buildings.

Water leaks at shut-off sites taps and valves water pipes in water supply systems represent an acute problem such as, in particular, consequences, such as:

- have a place (in the country) colossal mismanagement of water loss, causing great economic user, especially in regions with water scarcity;

- caused inconvenience, mental suffering, additional expenses to the tenants of high-rise buildings in cases where, for example, in one of the apartments it is necessary to replace the sealing gasket shut-off valves taps, and installed inside the apartment valves do not provide full coverage of water supply by water (especially hot water), thus, it is necessary to seek the assistance of the security services and resort to blocking of water flow around the house the riser-water, which entails the blocking of water flow to all other tenants living on other floors, and such events are almost emergency (unexpected) for many residents it stopped washing or other planned works; then (after the resumption of water supply) for Dov is the super long period of time goes dirty (rusty) water (such situations occur, in particular, deterioration, contamination in the form, scale buildup, rust airframe assemblies of valves in the long-term operation, as well as defects of their production).

The solution to this problem is devoted to the present invention, the essence of which is revealed from the further description of the drawings, which depict the following:

In the process of operating taps is the primary wear the most vulnerable parts, elements and components that are most vulnerable to the effects of corrosion, physical and mechanical loads.

In case 1 water tap most wearing seat is an annular flange 2, herpes vodovypuske hole 3, side surfaces in contact with the sealing gasket 4 shut-off valve valve 5, for the reason that this place feels complex load, namely, the effect of corrosion due to constant contact with moisture and the atmosphere; the erosion - corrosion of streams of dirty water after accidents, repairs, when the flow of water with rust from the pipes are Soboh the abrasive medium (slurry), the effects of water hammer and cavitation, plus frequent mechanical abrasive action with the sealing strip 4 when the opening-closing Vodopyanova holes 3 deposited on its surfaces with abrasive particles; and the valve 5 of the most intense wear-prone sealing strip 4 (Fig 1).

It should be emphasized that the wear of individual elements, parts and components is not uniform and dispersed in the most vulnerable areas due to the heterogeneity of alloys, having in its structure defects such as slag inclusions, oxide destroyed, the gas shell and the surfaces of microeconom, microconvex, due to manufacturing techniques (casting, stamping, machining cutting and so on).

Preventing leakage of water due to deterioration of the sealing strip 4 is eliminated by replacing the latter with a new one and no problems (either economic or operational) does not cause, as the cost of the strips is minimal, and the replacement process is simple and short.

Maximum problems occur when the flow of water occurs due to wear of the annular flange 2, when the end surface in contact with the sealing gasket 4, the formation of defects in the form of bumps, cracks, grooves 6, in which the issue is ensured and water flows through the water outlet channel, the negative relief of defective prints on the surfaces of the sealing strip are shifted relative to the positive relief of defects on the surfaces of the annular flange at each subsequent opening-closing, and therefore it is necessary very often to replace the sealing gasket and make great efforts to arm 8 to ensure that you growing force pressing the sealing strip to the end of the annular flange, which leads to rapid wear of strength thread locking mechanism and the arm, resulting, ultimately, comes this degree of wear to prevent flow of water it is not possible by any means, even by installing a new valve 5 (Fig 1).

Many famous invention aimed at solving the above problems by improving the taps and their separate units, but their service life (durability) limited physico-chemical properties of the alloys (bronze, brass), from which they are made, technology and operating conditions; including such well-known inventions, note the following.

In more detail the nature of the inventions disclosed from the further description of the drawings figure 1-9.

The initial process steps of the method of removing water leak in the shut-site water tap are: removing the valve 5 from boarding threaded socket 9 of the housing 1 water faucet and replace the sealing strip 4 in the shut-off valve (replacement inserts are required, since the former operation is embossed prints worn surfaces of the end of the annular flange and for future use unsuitable) (1, 2).

Then make a removal of the defective layers of metal thickness S from the end face 10 of the ring flange 2 (figure 2), using two versions of the device for removing water leak in the shut-site water faucet, namely: the first option specified in the device represented by the drawings, figure 3, 4, 7, and the second option specified device presents drawings figure 5, 6.

In the first embodiment of the specified device for removing defective layers of metal thickness S end 10 calcev the first flange 2 (figure 2) use a pre-made special cutting tool, representing a spindle 11, which consists of cutting head 12 for removal of the defective layers of metal, two coaxially jointed cylinders 13, 14 of different diameters (namely, the cylinder 13 of small diameter and cylinder 14 of large diameter and shank 15 for connection to the drive devices (3, 4, 7), and all elements (metal cutting head 12, the cylinders 13, 14 and the shank 15) spindle 11 coaxially between and coaxially boarding threaded socket 9 (that is, the cylindrical surface 16 of the landing threaded socket 9), internal palkopowerposts cylindrical part 17 and the annular rib 2 (2-4, 7).

The cylinder 13 is coaxially connected to the cutting head 12, a cylinder 14 is connected with the shank 15, the diameter d1cylinder 14 is larger than the diameter d2cylinder 13, the diameter d2cylinder 13 is greater than or equal to the diameter d3cutting head 12, and the diameter d3cutting head 12 is larger than the diameter d4the annular flange 2 surrounding vodovypuske hole 3 (Fig 3, 2).

Length l1cylinder 14 must be greater than or equal to the length l2; boarding threaded socket 9 of the housing 1 water tap; length l3cylinder 13 is defined, installed, selected on the basis of the length 14 of the cutting head 12 and sizes of existing, exploiter is controlled taps (figure 3, 2).

The cylinder 14 of large diameter d1precisely oriented relative to the cylindrical contact surface 16 landing threaded socket 9 of the housing 1 water tap so that the gaps between their contacting cylindrical surfaces (namely, between the cylindrical surface 18 of the cylinder 14 and the cylindrical surface 16 of the landing threaded socket 9) amount to a value not greater than 0.1 mm (Fig 3, 2).

The cylinder 13 of small diameter d2located on the inner palkopowerposts cylindrical part 17 (and therefore relative to the cylindrical surface 16 of the landing threaded socket 9) with a gap precluding contact between them (figure 2-4, 7).

In the drawings (Fig 3, 4, 7) as the cutting head 12 presents the option of using an abrasive tool in the form of a grinding round straight cylinder, but please keep in mind that as the cutting head can be used numerous other metal cutting tools such as end countersinks, milling.

As the cutting head 12 all applicable direct cylinders made of ceramic, cermet, brick, solid minerals cement.

The spindle 11 can have a different layout-structural design, in particular when all of its elements: cutting the head 12, the cylinders 13, 14 and the shaft 15 is made as a separate legkosbornyh and meghrashen parts, or modules, for example, using threaded connections (3, 4, 7).

In the drawings (Fig 3, 4, 7) as the example shows a variant of the spindle 11 when the cutting head 12 has a through axial hole through which it is connected with the cylinder 13 by means of screws 21, screwed into an end-to-end axial threaded hole 22 made in the metal parts of the spindle 11.

In the second variant of the device for removal of the defective layers of metal thickness S from the end face 10 of the ring flange 2 (figure 2) use a pre-made special cutting instrument representing the spindle 23, which consists of cutting head 24 for removal of the defective layers of metal, cylindrical Cup 25 for precise orientation of the spindle and fastening of the cutting head and shank 26 for connection to the drive devices (5, 6).

The outer cylindrical surface 27 of the glass 25 is accurately oriented relative to the contacting cylindrical surface 16 landing threaded socket housing 1 water faucet due to the fact that the gaps between these contacting surfaces 27 and 16 constitute a value not greater than 0.1 mm (figure 2, 5, 6).

The inner cavity of the Cup 25 (figure 5), is the th for fixing it cutting head 24, it is advisable to run in a straight circular cylinder or a truncated straight circular cone when their alignment with the outer cylindrical surface 27 (as example in the drawings, figure 5, 6), the inner cavity is made in the form of a straight circular cylinder, while the length L of the internal cavity set with the fixed length in her cutting head 24.

Cutting head 24 is fixed inside the Cup 25 in its inner cavity does not contact with the inner palkopowerposts cylindrical portion 17 of the housing 1 of the valve so that its flat end surface 28 is oriented perpendicularly to the outer cylindrical surface 27 of the glass 25, and the outer cylindrical surface of the cutting head 24, the outer cylindrical surface 27 and the inner cylindrical or conical surface of the cavity of the Cup 25 coaxially boarding threaded socket 9 and the annular flange 2 of the valve body 1, and the outer diameter d5cutting head 24 is larger that the outer diameter d4the annular flange 2 surrounding vodovypuske hole 3 (2, 5, 6).

In the drawings (figure 5, 6) as the cutting head 24 presents the option of using an abrasive tool in the form of a grinding round straight cylinder, but please keep in mind that it is the number of cutting heads can be used numerous other metal cutting tools such as end countersinks, face milling cutters.

As the cutting head 24 applies a round straight cylinders of: ceramic, cermet, brick, solid minerals cement.

In the drawings (figures 1, 2, 4, 6-9) as the example shows one variant of the design of the housing 1 water faucet when the case 1 is made so that its inner cylindrical surface of planting threaded socket 9 and palkopowerposts parts (i.e. the surfaces 16 and 17) have the same magnitude (size) diameter, however, it must be borne in mind that there are design taps, in which the diameters of the cylindrical surfaces 16 landing threaded sockets 9 more diameters of the cylindrical surfaces 17 palkopowerposts parts, it is necessary to emphasize that thanks new essential features and data parameters of the described invention are suitable, applicable for all types of existing taps.

Remove the defective metal layer thickness S from the end face 10 of the ring flange 2 surrounding vodovypuske hole 3 (figure 2), enter the spindle 11 (3) into the case 1 water faucet to contact the end surface 19 of the cutting head 12 with an end face 10 of the ring flange 2 (figure 4) or similarly injected spindle 23 (figure 5) inside corpus to contact the end surface 28 of the cutting head 24 with an end face 10 of the ring flange 2 (Fig.6).

In order to reduce application materials further technological process is described only using the first variant of the device for removing water leak in the shut-site water valve (figure 4, 7).

The process of removing the defective metal layer thickness S messages produced by the spindle 11 rotation with simultaneous pressing of the cutting head 12 to the end face 10 of the annular flange 2, while periodically spindle 11 of the housing 1 water tap for production control and quality assessment visual inspection.

Remove defective metal layer thickness S from the end face 10 of the ring flange 2 can be done by preliminary draft of removing the metal layer, for example, using a coarse grit grinding heads and the subsequent thin, finishing, finishing a fine-grained emery grinding heads.

It should be borne in mind that the wall thickness of the annular flange 2 from the side end face 10 may be only 1-2 mm, and it is therefore necessary to exert minimal effort pressing the spindle 11 in the removal process is the removal of the defective layers of metal.

As drive devices attached to the shank 15 of the spindle 11, is suitable, for example, a drill with electrical and mechanical drives, tap wrenches, rotations, chucks (figs.4, 7 accession Pref is-breaking devices to the shank not shown).

After removal of the defective metal layer thickness S (7) the spindle 11 is removed from the housing 1 water tap, resulting in the annular flange 2, a new end surface 29 in contact with the sealing gasket shut-off valve, oriented perpendicular to the cylindrical surface 16 of the landing threaded socket 9 (Fig).

Then make the cleaning housing 1 water tap from small chips, for example, by rinsing with water, and again fix the valve 5 in the boarding threaded socket 9 renovated housing 1 water tap, press the sealing strip 4 to the end of the annular flange 2 and resume the flow of water through the pipeline, i.e. lead hydrant in normal operating condition, when this flow of water is eliminated thanks to a tight, reliable fit to each other, the contacting end surfaces of the sealing strip 4 and the annular flange 2 (Fig.9).

Here it must be emphasized that a tight, reliable fit to each other end of the contacting surfaces of the annular flange 2 and the sealing strip 4 with minimal effort pressure (after removal of the defective metal layer from an end face of the annular flange) is provided, is achieved automatically thanks characterized enter the constructional-technical parameters of the described inventions.
