The present invention is of use throughout type of plumbing installations for both gas and water made in homes or establishments.

State of the art

+ The Spanish patent ES 2 025 896 ( David Moliner Vergara ): " Security system against domestic flooding or similar ". claim:

1. Flood safety system domestic or similar, characterized in that it is constituted with some  moisture detecting elements intended to be placed on the ground or bottom of places where they may exist leaks or water leaks, said detectors going related to an electronic circuit, as activation control means thereof, which circuit is in turn constituted in the middle of control and governance of a possible system optical-acoustic signaling and / or a system automatic cutting of the passage of water through the attached pipes, so that before an improper presence of water in the place the detectors bring the system into operation, causing the activation of the signaling means and the cutting of the conductions

This is a security system afterwards , once the breakdown and subsequent flooding have already occurred. It is not, therefore, a preventive system like the one advocated by the presented invention.

+ The Spanish Utility Model U 200502739 ( Manuel Sarmiento Perera ): " Domestic digital control system for electricity, water and gas supply meters ". In his second claim he cites:

2. Domestic digital control system for electricity, water and gas supply meters, according to the 1st claim and characterized by having a computer personnel connected to the automaton and intercommunicated by means of a data transmission system to data processing centers from the offices of the supplying companies that allows you receive orders for cutting operations and supply replenishment thanks to the presence of mechanisms based on electro-valves or power switches connected to the automaton and the supply connections.

In this case it is a control system by the supplying companies that the unpaid supply cut. It is therefore not comparable to potential of the present invention.

+ The Spanish Utility Model 1 063 176 ( Miguel Ángel Villanueva Cortijo ): "Home automation plant ". It consists of a two-way telephone communicator that allows the subsequent detection of a gas failure in the home:

3. Central, according to any of the claims 1 and 2, characterized in that the transmitter bidirectional telephone (11) comprises at least one connection (24) to a gas detection sensor (25) and its corresponding solenoid valve (26) to detect a leakage of domestic gas.

The aforementioned Model allows to control telephone leaks and other problems, but always at posteriori, not affecting the essence of the present invention.

We conclude, then, that the existence of a system that automatically allows cutting of the water and gas circuits of a building, home or premises to avoid breakdowns during their absence.

Detailed description of the invention

Automatic water supply shut-off valve and gas for leak prevention during periods of absence and / or no use of housing, premises, ship or hotel room, or establishments

This system aims to prevent leaks in water and / or gas supply or in any installation of plumbing done in homes or establishments, contributing This way you avoid unwanted situations.

The infrastructure in question will support the system of cutting the passage of water or gas in homes or establishments (industries, premises, hotels) and can be installed in hot and cold water facilities in room bathrooms, hotel kitchens, industrial warehouses, public toilets, In short, in all those places where you can use cold, hot water and gas. This infrastructure will be composed of an automatic cut-off key directly connected to motion sensors and timers which will preferably be placed in the rooms where the water and gas installations reside, for example bathrooms and kitchens, or in the access to the housing, premises or rooms. Said sensors will detect the movement, for example, at the entrance of the home and will proceed to send a signal by means of a relay or relays and programmer that will cause the opening of the water and gas stopcocks of the house or room. This installation, can be applied simply to the desirable stay by the client without having to affect the general key of the house. Such is also the case of hotel establishments, where the unoccupied rooms can be cut without affecting the installation of the rest of the
building.

The operating system would be as follows:  By combining one or more motion sensors, relays and a timer, we proceed to perform the installation of the components whose work process will be the next:

-

To the Enter the tenant at home or premises, your move will be detected by the sensor, which will send an order to the relay that proceed to open the gas and water stopcocks of the house. Once inside the tenant / s will enjoy the supply of water and gas until the timer stops detecting movement in the address Thus proceeding to cut the supply in this space of time in which no movement is detected, said space Time will be programmable by the customer.

-

This It may be applicable in the following example: we enter the housing the sensor detects the movement proceeding to open the stopcock Then we put the washing machine to wash, we program the  timer with the time the washing machine needs to finish the washing process. Once we do this we leave home and the cut will occur after the scheduled time after The sensor does not detect movement.

The smart key is a solenoid valve that It will open and close automatically depending on the orders received and sent by the components 2-2i-3, 4, 5.8.

The solenoid valve will close, for example, at 2.5 hours after there is no movement in the house, which is understood that the owner is not in the housing and there is no need for water pressure in the installation; the solenoid valve would be at rest until it detect movement in the house, after the last movement detected by the detector could take a certain time to the solenoid valve is closed leaving a minimum time for that can remain working since there are devices that need water consumption for a certain time and then closes of automatically

Embodiments of the invention

In a first preferred embodiment of the invention, represented in scheme 1 we have the key intelligent that is formed by a thermal 2-pole (1) to the 10A electrical panel input, a motion detector (2) that will be located at the entrance of the house or stay, above from the door, as long as it reaches all entrances to premises damp, bathrooms, kitchens, toilets, etc. to get the most out of it performance and do not leave dead zones. The relay (3) picks up a signal sent by the motion detector and sends it to the programmer (4)  in the form of an electrical impulse, which uses this signal to make operate proportional timers and through this timer (programmer) (4) we operate an electro valve (5), which will leave us the plumbing installation with or without service, the installation of the electro is advisable valve in the water inlet pipe to the dwelling or room in order to cancel the maximum possibility of breakage or leakage in the  housing or common areas (areas to protect from floods). At electrical panel there are some LEDs of information that will indicate us in every moment the state of the solenoid valve, Led (6) (red) closed solenoid valve, led (7) open solenoid valve (green).

In a second preferred embodiment of the invention, represented in scheme 2, we have the option of be able to install the smart key so wireless, ideal for renovations or existing installations, in addition if you have the same benefits as the one in scheme 1 you will be incorporates a wireless motion detector (2i) and a receiver (8).

In a third preferred embodiment of the invention, represented in scheme 3, extends all the operation of the smart key in scheme 1 (designed to water), incorporating the option of making the water smart key and gas with which we will close the water and gas keys, after a period of time determined by the client; This weather usually fixed once the installation. The solenoid valves are they will close after the set time, after the last movement detected by the detector (2).

With this smart key we will be able to close the passage of gas, in case we are not at home (there is no movement in the dwelling or stay), through a solenoid valve in the gas tube, we would only have gas if the room thermostat demands heat (the boiler turns on) then the room thermostat (12) gives a signal to the relay (11) and the boiler is switched on via contact (13) of the relay and simultaneously the contact (15) of the relay (11) gives order to the solenoid valve (10).

How interior gas installations give countertop service, once motion is detected in the housing or stay would activate the solenoid valves simultaneously of water and gas, being able to program the timer with different closing time with respect to the water programmer since when the order room thermostat will turn on the gas boiler and solenoid valve regardless of whether movement in the dwelling or stay for as long as stay the room thermostat demanded heating, the boiler will remain on, we will know the position of the solenoid valve of gas through the yellow Led (13).
