Description

TECHNICAL REPORT

From the industrial invention entitled: device for collecting water leaks in built-in boilers

FIELD OF APPLICATION TO WHICH THE INVENTION REFERS: thermohydraulics

BACKGROUND OF THE TECHNIQUE:

at present there are no solutions to the problem, which means that water leaks for any cause from any part of the built-in boiler components, involves the absorption of the same water by the masonry surrounding the boiler casing . The presence of humidity due to the absorption of water tends to migrate both towards the inside and the outside of the masonry; this phenomenon produces on the one hand the impoverishment of the construction materials, with the alteration of their original properties, on the other hand it causes the plaster degradation due to the crystallization of the salts contained in the same constituents of the masonry. The deposit of saline crystals on the surface of the surrounding artifacts also gives rise to the phenomenon of efflorescences which appear as thickenings for the most part whitish in color. All this transforms into a superficial crust that leads to the obstruction of the empty capillaries in correspondence with the facades of the wall system, which leads as a consequence to the enlargement of the damp spots, triggering a degenerative process, which leads to detachment of the plaster.

This degenerative phenomenon can be avoided by installing the water collector device referred to in this patent at the base of the boiler door casing.

GOAL THAT INNOVATION INTENDS TO ACHIEVE:

very often water leaks occur inside a boiler due to:

- cracks in the expansion tank,

-cracks in the main exchanger,

- opening of the safety valve,

- loss of the automatic vent valve,

- connection between pipes and boiler, etc, etc,

with consequent infiltration of water leaks in the masonry.

the aim of the innovation is to avoid damage to the walls (surrounding the built-in boiler door), due to water infiltration caused by the various aforementioned reasons.

The device to be patented is placed at the base of the box in which the boiler is installed, and sealed with silicone to the same box.

The shape of the collector device depends on the model of boiler installed, but all the devices have:

- Hole for the passage of the return-heating pipe (see fig.1 page4 n.1) - Hole for the passage of the delivery-heating pipe (see fig.1 page4 n.2) - Hole for the passage of the sanitary water return (see fig.1 pag4 n.4) - Hole for the passage of the sanitary water delivery pipe. (see fig.1 page4 n.5) - Hole for the passage of the boiler-condensate feed pipe (see fig.1 page4 n.7) - Hole for gas inlet. (see fig.1 page4 n.8) - Hole for the passage of cables for remote panel control

o room thermostat (see fig.1 page4 n.9) - Hole for the passage of electrical power cables. (see fig. 1 page 4 n.10)

In addition, there will be three through holes on the device, to which they must be connected:

-in one, at the boiler side, the connection of the safety valve (see fig. 1 page 4 n.11),

- another (see fig.1 page 4 n. 6) is used to collect leaking water from any point of the boiler through channels dug on the base of the device (see fig.1 page 4 n.12).

- the third hole on one side connected the condensate drain pipe (see fig. 1 page 4 n. 3), on the other through a bushing (see fig. 1 page 4 n. 13), the pipe which drains the condensate directly into the water drain of the home system,

From the part below these holes (safety valve and water leakage) respectively (n.15) and (n.14) are welded some bushings to which two pipes are connected which through a special piece (Ti fitting at 45 °) (see fig. 2 pag. 4 n. 16) flow into a single pipe for the expulsion of the water outside the box, so that the user can notice the leak and call the plumber to repair the damage, (see fig. 2 page 4).

In the bushings under the device, the exhaust pipes with diameter Ï † 32 are connected respectively:

If polyethylene pipes are used, mechanically tighten fittings.

If using pvc pipes glued with mastic.

Looking inside the box after installation, you will see only the part facing the boiler, since the lower part of the device with the respective bushings and drain pipes in pvc or ptr (see fig. 2 pag. 4 n. 14-15 and 16) -they will be drowned inside the masonry, and when the pipes for the expulsion of the water are finished, the only thing that will be seen will be, (in the wall where the boiler is embedded under the door of the caisson) a drip hole, from which the water leak will come out (see fig. 2 page 4 n. 17).

Please note that the number of passage holes made in the water collection device that you intend to patent depend on the type of boiler installed by the user, so if you have a boiler that needs seven holes, it will be a binder device with seven holes. Possibly, if you use, a collector device with more holes than you need, for example six holes (condensing boiler), but the boiler is a traditional type that needs 5 holes, the relative hole more or closes with watertight cap or it can be used as an additional water drain.

The collector device is made of either plastic or resin. In the holes for the passage of the pipes, watertight gaskets are provided to prevent water from infiltrating these points. While always to avoid the passage of water through the electrical power supply wires or the wires for remote panel control, cable glands will be used in the relative passages.

For a better understanding of what you want to patent, the following is attached:

- plan, elevations and sections (see pages 5 and 6, fig. 3-4-5-6-7)

- 3D models (page 7)
