Abstract

The invention relates to an integral system for a toilet tank comprising an hydraulic piston that uses the pressure in the domestic water piping system, multiplies said pressure and converts same up to 35 kg. The aforementioned piston is applied at the outlet of the tank through which water enters the toilet. Said piston never leaks and can be easily installed in any low toilet tank. The flush process is performed hydraulically using a standard lever and is supplied by a lower connection inside the tank which extends from the column in order to supply the float. The invention does not relate to the float but simply refers to same owing to the fact that it is a float with ceramic valves which does not leak during approximately 100 years of use. Ultimately, the column of the installed float may be used provided that a connection is added thereto to supply the hydraulic valve which is fitted with an overflow.

Description

INTEGRAL SYSTEM FOR TANK OF

TOILETS

BACKGROUND

Currently, a large majority of the toilets of houses, condominiums, hotels, etc., are traditional low tank toilets, the low tanks of these toilets, are equipped with the fittings that include a shutter for the discharge that closes by gravity to the fall on the tank outlet, thus preventing the flow of water to the toilet bowl; since the shutters must be able to float on the water when the toilet bowl is operated and are made of very light materials.

When closing, it is the simple weight of the mentioned shutters, which prevents water from escaping; this closure is further reinforced by the weight of the water that is in the low tank and that accumulates on the shutter as the tank fills; However, the height of this water tank will rarely reach more than 25 cm in height, so the force with which the water outlet closes to the cup is relatively small (varies according to the toilet model between 0.5 and 1.2 kilograms) and any imperfection in the seat or in the shutter causes constant leaks in the low tanks. Sometimes the deposits of algae or lama that are formed in the same shutter or its seat are sufficient to prevent closure, with the consequent leakage of water or leakage 24 hours a day.

The water that leaks from the low tank, falls into the bowl (or toilet) and from there, it passes to the drain, so this type of leakage goes unnoticed and therefore is not corrected, so a toilet can pass years throwing water without anyone noticing (Silent Fugue).

The other leaks due to the poor quality of the parts and their designs, cause serious waste that without operating the toilet, have been estimated at up to fifty percent of the water supply to the cities.

The most similar antecedent that uses the principle of taking advantage of the pressure of the hydraulic network of buildings, is the so-called fluxometer, or discharge valve, but this cannot be used in low tank toilets, since the characteristics of both the same toilet, as the hydraulic network are different from those that exist in the normal facilities of a house and such devices require special hydraulic installations and a load of at least 2 K / cm ² (20 meters high) .

These drawbacks are indicated in order to demonstrate the scope of the present invention, since it does not exist in the world market a toilet discharge valve, which uses the existing water pressure in the domestic hydraulic network of the building or house, to close the low tank with great force and discharge without water dispensing.

The objective of this new system is to reduce the possibility of leaks in the discharge valves of low tank toilets to zero.

This system is composed of a hydraulic piston that uses the pressure of the hydraulic network.

DESCRIPTION OF THE INVENTION

The present invention relates to the improvement in the valve for closing and unloading the low tank of the toilets, commonly known as "perfect pear" or "toad". The improvement is based on the fact that this new hydraulic valve applies a weight of ten or more kilos directly to the tank discharge and never leaks. Said hydraulic valve uses the energy existing in the hydraulic network to close and discharge, thus avoiding leaks, which in the traditional systems are constant; since they only receive the push of the weight of the content inside the low tank of the toilet to realize the closing.

FIG. 1 shows the valve for the toilet tank, in its upper and lower views. FIG. 2, is an elevation of the same valve.

FIG. 3, is a cut-out scheme of the operation in the open position.

FIG. 4, is a cut-out scheme of operation in closed position.

FIG. 5, shows the exploded view of the toilet valve

FIG. 6, is an isometric drawing of the toilet valve.

With reference to these figures, we describe the assembly of the parts; starting with the part (No. 19) that is the counter sput (No. 12) and that when pressed to the rubber bands (No. 15), seals up and down the porcelain, avoiding leaks from the low tank.

The whole system piece (No. 12), forms a single piece with the sput.

The piston (No. 7) that is provided with a rubber (No. 10), when penetrating the cavity of the base (12) seals with the force that comes from the arrow (No. 4) and that is applied in the piston, making a completely hermetic seal.

The arrow (No. 4) is assembled with its outer rope to the inner rope that is observed in the piston (No. 7) and that transmits the weight of the closure. The base cover (TB) or piston support, which with three columns (No. 17), are placed in the base (No. 12), supported and tightened with 3 nuts (No. 18).

The arrow (No. 4), in its upper part has the piston (No. 5) with the o'ring (No. 6) and penetrates the vessel, thereby forming chambers A and B, which alternate in their operation by opening or closing the system. On one side of the chamber vessel (A and B), the duct (No. 1) is incorporated, which when the vessel is assembled with the base (TB), channels the water and only restricted by the set that forms the prisoner (N ° 9), which allows the adjustment of the volume that must be directed to recover the water mirror after a discharge.

The inlet (No. 3) receives the water that is channeled into the chamber (B), the outlet (No. 2) releases the water pressure from the chamber (A) allowing depressurization, which achieves the sudden rise of the piston and therefore of the piston, which allows the discharge of water from the tank to the toilet.

In an enunciative way, but not limited to and based on the drawings described above, the hydraulic valve for low tank discharge of my invention, is made of a multiplicity of parts, which once assembled function as a unit and basically consists of two operations : 1. Pressurized with seal and 2. depressurized and discharge; Both hydraulically. PRESSURIZED WITH HERMETIC CLOSURE.

It is the filling of the chamber (A), which contains the piston (No. 5) that drives the piston (No. 7) down with the arrow (No. 4) when it is filled and pressurized by means of the tube or hose (No. 1), connected to the cold water network and which makes hydraulic pressure over an area between: 12.56 cm ² (for high pressure with a 4 cm diameter piston and 28.27 cm ² , when it is a piston which has an inner diameter of 6 cm) the original diameters of the inner vessel and the plunger can be varied depending on the requirement, in this case a diameter of four centimeters was designed for the first surface and for the second a diameter of six centimeters, with the which basically covers the need for virtually any pressure at which water is found for human use in municipal networks and in domestic networks.

When injecting through the tube or hose (No. 1), the hydraulic pressure for example: one kilo per square centimeter on the surface of the plunger, given that there is 12.56 cm ² in that area, the weight transmitted to the piston (No. 7), is 12.56 kg permanently which makes a tight seal of the piston against the rubber gasket (No. 10), which does not allow the tank to have any leakage, thanks to the weight mainly because the jagged characteristics of the rubber (10). DEPRESSURIZED AND DOWNLOAD.

The second operation, which is the discharge of the WC tank to the toilet, is carried out by opening for a moment the valcer valve (ceramic valve) (No. 8), by means of the operation of the lever (No. 13) (which returns automatically thanks to a spring), and suddenly depressurizes the pressure exerted on the upper part (chamber A) of the piston (No. 5) and this water spills into the tank through the tube (No. 19) and aided by the injection of water from the network, which automatically enters through the tube (No. 3), in the lower part of the piston (No. 5 or chamber B) and instantly drags the piston upwards (No. 7) , allowing a quick discharge of all the water from the tank to the toilet.

Thanks to the prisoner (N ° 9), which is adjustable and manually regulates the time in which the piston falls, it is possible in each case, for each toilet or wc to leave only the time strictly necessary for the water mirror to recover of the toilet; This results in additional savings as traditional systems commonly throw a lot of water down the small tube from the float valve to the overflow, while the tank is filling and they are not adjustable. Although the water inlet (No. 3) is greater in volume, when filling by the valve (No. 1) is initiated due to the difference in areas between one and the other, the pressure of the closing chamber (A ), which has a larger area, gradually defeats the opening chamber (B) and this pressure predominates until the next unloading operation. PISTON OPERATION

When starting the pressurized with hermetic seal that is the filling of the chamber "a" that contains the piston No. 5 that drives the piston No. 7 down with the arrow No. 4 when it is filled and pressurized by means of the tube or hose No. 1, connected to the cold water network and making hydraulic pressure. at that moment the piston No. 8 is fed with a volume of water regulated by time (previously established). The rear chamber of the piston No. 8 is filled, which drives an arrow No. 21 by means of its plunger, which, with a lever, starts the closing of the filling valve and is a function of time and volume of water, as stated before it is established once when the equipment is instilled and will repeat its function each time the discharge lever is operated.

DEPRESSURIZATION OF PISTON No. 8

When operating the pressurization chamber lever, the content of the piston No. 8 that pushed the plunger is opened and emptied and that when opening the discharge automatically operates a chek valve that contributes to depressurization and allows the pressurization of the anterior part which gradually closes the power to the tank according to what was previously programmed and only allows the output of six liters that supposedly turns out to be programmed. IN THAT INSTANT THE FOLLOWING HAPPENS:

1. The piston No. 8 that was pressurized on its back when the lever was operated. It empties suddenly, when the piston is pushed by the constant pressure of the anterior chamber.

2. The lever that comes out of piston No.8 towards the filling valve suddenly opens and starts filling the tank.

3. The pressurization of the previously regulated rear chamber is started to fill only the preset level and that replaces the float with this, admitting, in its rear part, the volume necessary to bring the arrow of the plunger to its final destination which is to close the filling valve.

4. When operating the discharge, and through a vein that comes from the pressurized area, the back of the piston No. 8 is filled, starting slowly and as programmed, the total closure of the water inlet.

NOTE: The system has been equipped with an overflow (N ° 16) that only serves so that in case of a rupture or some damage that floods the tank to the top, instead of overflowing into the bathroom, the water goes to the overflow mentioned .
