Description

DEVICE FOR PROTECTING WATER HOSES The technical field to which the invention relates.

The invention relates to devices for protecting water hoses, including a protective casing and means for attaching a protective casing, and can be used to trap and drain into the sewer water flowing from torn water hoses, for example, flexible hoses, and pressurized joints.

The level of technology.

If there are connections between water pipes and each other and with various plumbing objects, there is a risk of leakage. It is associated with the possibility of a breakthrough of the hose itself or leakage at the point of its attachment, for example, due to the displacement of the gasket. The consequences of the leak are very noticeable not only in production, but also in everyday life, for example, if, as a result, the apartment located below the floor was flooded.

To prevent this, protection options have been invented that are based on the possibility of removing water flowing from torn water hoses, for example, flexible hoses, and pressurized joints.

So it is known from the prior art a device for protecting water hoses, including a protective casing and means for attaching a protective casing, see the description of the patent for the invention of the Russian Federation Ns2511926, published in 2014.

This device is the closest in technical essence to the claimed invention and is taken as a prototype to the proposed invention.

The disadvantage of this device is the inability to use the device on already mounted connections of water hoses. Indeed, this device is produced immediately at the factory together with a protected hose, and therefore it cannot be used in existing plumbing connections.

Disclosure of the invention. Based on this original observation, the present invention mainly aims to propose a device for protecting water hoses, including a protective casing and means for attaching a protective casing, which allows at least to smooth at least one of the above disadvantages, namely, to expand the area the use of the device due to the possibility of using it on already mounted connections of water hoses, which is the technical task of the present invention.

To achieve this, the protective casing has a middle part made in the form of a corrugation, having the ability to change its length, and made with the possibility of placing inside it a protected water hose, while the protective casing has end parts made in the form of cylindrical sections that can be placed inside there are places for connecting the protected water hose, and the middle section has a nipple for draining water in case of leakage of the water hose or the place of its connection.

Thanks to this advantageous characteristic, it becomes possible to install this device on already mounted connections of water hoses. And in addition, it becomes possible to use this device in the process of installing flexible eyeliners.

To do this, you just need to disconnect the water hose, put the proposed device on it, attach the water hose back and seal the edges of the proposed device. The middle part of the protective casing is made in the form of a corrugation. This distinguishes it from a corrugated pipe, which can change the geometry, but does not change the length. The corrugation, on the other hand, has the ability to stretch and contract like an accordion. Thus, the protective casing allows access to the joints of the water hose. More installation of the device will be described in the chapter "implementation of the invention."

There is a possible embodiment of the invention in which the nipple has a valve. Thanks to this advantageous characteristic, it becomes possible to place the nipple anywhere, water will only leak out when a certain level of water is reached in the space between the protective casing and the water hose. The valve in the nipple is needed so that the water in the case of full filling of the inner space of the protective casing does not go in the opposite direction.

There is a possible embodiment of the invention in which the end parts of the protective casing have locking clamps. Thanks to this advantageous characteristic, it is possible to additionally fix the end parts of the protective casing during its installation.

There is another possible embodiment of the invention in which the end parts of the protective casing have sealing cuffs. Thanks to this advantageous characteristic, it becomes possible to install the device on different types of water hose connections.

There is also an embodiment of the invention in which the sealing collars are cylindrical or conical. Thanks to this advantageous characteristic, it becomes possible to expand the sealing capabilities of the water hose connections.

In addition, there is an advantageous embodiment of the invention in which the protective cover has a leak indicator. Thanks to this advantageous characteristic, it becomes possible to signal this when a leak occurs. Indeed, in the absence of such an opportunity, it becomes unclear whether there is a leak or not.

There is a possible embodiment of the invention in which the leak indicator is in the form of a spiral rubber tube. Thanks to this advantageous characteristic, it is possible to easily perform a leak indicator. When it is placed below the protective casing, in the direction of gravity, in case of leakage, water will fall into a spiral rubber tube, which will begin to unwind under the weight of the accumulated water and will change its shape.

There is an alternative embodiment of the invention in which the leak indicator is in the form of an electrical sensor. Thanks to this advantageous characteristic, it is possible to send an electrical signal to the security control panel, activate an audible or visual alarm, or automatically send a CMC message about an accident when the contacts of the electric sensor are closed by water, which appears in the event of a leak.

There is an advantageous embodiment of the invention in which the protective cover is made of polyvinyl chloride. Thanks to such a profitable The characteristic gives the possibility of a clear and proven manufacture of a protective cover.

There is an advantageous embodiment of the invention in which the end parts of the protective casing have an external thread and have additional union nuts. Due to this advantageous characteristic, additional mounting possibilities of the proposed device appear.

There is an advantageous embodiment of the invention in which the end parts of the protective casing have internal spring stops. Thanks to such a favorable characteristic, additional possibilities arise for mounting the proposed device on the housing of sanitary products.

According to figures 1-12, the device for protecting water hoses includes a protective casing 1 (shown by the dotted line in figure 1) and means 2 of fastening the protective casing (shown by the dotted line in figure 1). The protective casing has a middle part, made in the form of a corrugation 1 1, with the ability to change its length, and made with the possibility of placing inside it a protected water hose 3. The change in the length of the middle part can be in the range of 0.5-2 from the original, “free length ". The protective casing 1 has end parts 12 made in the form of cylindrical sections,

b having the possibility of placing inside them the connection points of the protected water hose 3, and the middle portion 11 has a nipple 13 for draining water in case of leakage of the water hose 3 or the place of its connection. The end sections can be with a smooth surface, as well as with an external thread.

The nipple 13 may have a valve, which is not shown in the figures.

The end parts 12 of the protective casing may have sealing lips, which may be cylindrical 21 or conical 22.

The end parts of the protective casing may have fixing clamps 23. The protective casing 1 may have a leak indicator 4, made either in the form of a spiral rubber tube (see figures 11 and 12) or in the form of an electric sensor. (Not shown in the figures.)

The protective casing 1 may be made of polyvinyl chloride.

The end parts 12 of the protective casing may have union nuts 24.

The protective cover 1 is designed to collect water flowing from a torn flexible eyeliner 3 or from "aged" connecting gaskets. The protective casing 1 is a corrugation, easily compressible and stretchable within 0.5 -2 times. The ability to contract and stretch is necessary in order to: a) maintain a simple technology for installing flexible eyeliners;

b) - to preserve the technologies for serial production of flexible eyeliners when equipping them with “shell-traps” directly in the manufacturing processes.

The end parts 12 of the protective casing overlap the joints of the flexible hoses 3 with pipes or pipes 31 and provide the outlet to the protective casing 1 of the water flowing due to the "aged" connecting gaskets. The end parts 12 of the protective casing can be made with a smooth outer surface (See figures 1, 2, 4, 5, 7) or with an external thread (See figures 3, 8, 9, 10).

The nipple 13 is designed to connect a tube that discharges water from the protective casing 1 to the leak retainer or directly to the sewer. It can also be used to insert sensors of electronic protection systems into the nipple body.

The implementation of the invention. A device for protecting water hoses is used as follows. (A non-limiting example of use is provided). According to figure 13:

Stage A1. Cover the water in the system, unscrew the connection of the flexible eyeliner 3.

Stage A2. A protective casing 1 is put on the flexible eyeliner 3, reducing the length of its middle part 11. The position with the reduced length of the protective casing is shown in figure 5.

Stage A3. Reconnect the flexible eyeliner 3.

Stage A4. Fix one of the end parts of the protective casing 12, according to the options described below.

Stage A5. Stretch the middle part 11 of the protective casing, increasing its length.

Stage A6. Fix another of the end parts of the protective casing, according to the options described below. Connect the nipple 13 to the sewer or other place to drain leaked water.

When the flexible eyeliner 3 breaks or the connection point leaks, water begins to accumulate in the cavity of the protective casing and is discharged through the nipple 13, which discharges the leaked water into the sewer or any other place for water drainage. (In a country house, this may simply be a conclusion to the street).

A general view with a partial sectional view of the installation of the device is shown in figure 4. The gaps indicated in this figure as 5 are mandatory for the correct operation of the device. These are the gaps between the flexible eyeliner and the middle part of the protective casing, as well as the gaps between the end part 12 and the junction of the flexible eyeliner 3. Then water is discharged in case of breakthrough of the gasket in the joint or other leakage of the junction of the flexible eyeliner 3.

In the presence of leak indicator 4, the latter visually or otherwise signals that a leak has occurred. If the indicator is made in the form of a case containing a rubber spiral, but the unwinding of the spiral serves as a visual indication - see Fig. 11. The arrows in figure 11 shows the direction of unwinding-twisting of the spiral. The dotted line indicates the presence of leaks. The above embodiments of the invention are exemplary and allow you to add new options or modify the described.

These options include the following:

- The mounting option of the proposed device on a flexible eyeliner with a short fitting is shown in figure 6, (cylindrical cuffs 21 and clamps 23 are put on pipes or pipes 31 before installing flexible hoses 3. Then, after connecting the flexible hoses 3, end parts 12 are pulled on the cuffs 21 The clamps 23 tightly tighten on the end parts 12 and press the end parts 12 and cuffs 21 to the pipes or pipes 31. Thus, the water outlet is blocked.

- The mounting option of the proposed device on a flexible eyeliner at its junction with the ball valve housing is shown in figure 7. Clamps 23, and if necessary, cylindrical cuffs 21 are put on the end parts 12 before installing the flexible hoses 3. Then, after connecting the flexible hoses 3, the cylindrical cuffs 21 and the end parts 12 are pulled onto the bodies of the ball valves 33. The clamps 23 are tightened tightly, thereby blocking the water outlet to the outside.

- The mounting option of the proposed device with a union nut 24 on a pipe or pipe 31 is shown in figure 8. Union nuts 24 and conical cuffs

22 are put on pipes or nozzles 31 before installing flexible hoses 3. After connecting flexible hoses 3, end parts 12 are pulled all the way and clamped on pipes or tubes 31 with conical cuffs 22 and union nuts 24.

- The mounting option of the proposed device with a spring stop on the body of the sanitary ware 34 is shown in figure 9. The elongated fittings 323 are screwed into the housing 34 of the sanitary ware. Then the end parts 12 are pulled on with pre-screwed sealing sleeves 325 with O-rings 326. Echoing clicks indicate that the spring stops 329 have slipped and rested against the splines of the fittings 321. The protective cover 1 fixed in this way against the elongated fittings 323 allows the sealing cover 1 to be screwed up bushings 325 tightly press the annular collars 326 to the housing 34 of the sanitary ware. - A mounting option of the proposed device with thrust washers 322 on the body of the sanitary ware 34 is shown in figure 10. Elongated fittings
