MX2009012497A - Cold and hot water distribution valve. - Google Patents

Abstract

The present invention refers to a valve for distributing hot and cold water, which may be used in a distribution system where the cold water flowing upon opening the shower will be distributed to the toilet tank or any other deposit. The system comprises a valve that prevents the hot and cold water from flowing and leads said water to a control valve, which has the ability to lead the water to a toilet water tank.

Description

HOT AND COLD WATER DISTRIBUTION VALVE Field of the invention The present invention pertains to the valve area, and more particularly to a valve for distributing cold and hot water.

Background, A user regularly opens a hot water tap and lets the cold water flow, before the hot water comes out. This causes several liters of water to be wasted, just because it is not at the desired temperature for the bath. Therefore it is necessary to develop systems that allow the saving of cold water. . .; | Typical valves for distributing hot and cold water comprise a first inlet coupled to a cold water tank and a second inlet to a hot water tank to receive the hot and cold water from its respective tank. The valves include a mechanism to control the flow and / or mixing of cold and hot water. When the first inlet is incorrectly coupled to the hot water tank, and when the second inlet is incorrectly coupled to the cold water tank, hot water and cold water can be supplied wrongly.

In this sense, patent US 5011074 presents a thermostatic mixing valve. This valve includes a body that has a fluid inlet hot, a fluid mixing chamber and a fluid outlet in communication with the mixing chamber. A thermostat is inside the mixing chamber. In piston responsible for the flow of cold water through slots and a disk responsible for controlling the flow of hot water through a cylindrical tube containing grooves and an opening in the base of the cylinder It contains a spring that acts up against the movement down the thermostat.

US patent 1243999 presents a thermostatic hot water mixer. Cold water and steam are connected to an inlet valve. The thermostat comprises a metal diaphragm located in a cover filled with liquid. The steam is controlled to release hot water. A bar is connected to the diaphragm. An increase in temperature causes an expansion of liquid fluid within the diaphragm container and compresses it. This acts on the bar and closes the steam valve against the compression spring. The supply of cold water is constant and the steam supply varies to maintain the desired temperature.

Patent US 2211058 presents a device for mixing hot and cold water. A device moves to restrict a group of ports without affecting another group. This device is moved by a piston. To control the piston, the piston has opposite holes with slide valve montana in the holes. The valve moves in and out of the holes to restrict the flow of liquid from one side of the piston to the other in the mixing chamber. A metal strip controls the valve. The water temperature flexes the strip causing it to open and close the valves and move the piston to equalize the pressure on opposite sides of the piston when the temperature is correct. The cold or hot temperature causes the piston to move in one direction to equalize the temperature.

US Pat. No. 4286749 discloses a fluid mixing valve for mixing hot and cold water. Pressure means control the ratio of high and low temperature fluid flow. The cold water flow rate is varied according to the flow rate of the hot water. The changes in the pressure of the cold water cause a change in the flow velocity of the hot water. The pressure ratio of both fluids is maintained by a predetermined value. A movable member is responsible for opening and closing the doors according to the recorded temperature.

Due to this problem with the distribution valves, there continues to be a need for valves that solve this problem. Therefore, the present invention provides a new valve that allows hot and cold water to be distributed in such a way. that the cold water that would be eliminated when opening a shower, will now be directed to a deposit where it can be used for a purpose other than bathing.

Brief description of the figures Figure 1 is a perspective view of the water and cold distribution system, where (1) in the cold water inlet from a tank, (2) is a water heater, (3) is the water pipe, hot water, (4) is a bathroom shower, (5) is the valve for hot and cold water, and (6) is the water tank of the toilet.

Figure 2 is a side aerial view of the hot and cold water distribution valve, where the arrows indicate the cold and hot water inlets, respectively.

Figure 3 is a perspective view of the components of the hot and cold water distribution valve, where (7) are rubber gaskets, (8) is the valve shaft, (9) are two convex circular gums, (10) is a metal bar, (11) is the adjusting screw of the shaft.

Detailed description of the invention The present invention is relative is a hot and cold water distributing system containing a distributor valve. The function of the valve is that when the tap is open the hot and cold water remain in contact and by empathy the two temperatures tend to equalize; The temperature decreases when the water flows again and it goes cold through the shower. The valve contains a device consisting of two rubber or circular plastic convex (9) which are each connected to one end of a metal bar (10) This metal bar passes through a hole through the lower end of a key shaft (8). Turning the upper end of the tree will cause the two convex pieces to rotate; this rotation allows the gums to block the entry of hot and cold water. From this, the mixed water is directed to a control key (not shown), which directs the water to the toilet tank.

The system of distribution of hot and cold water is composed of, among other things, a hot and cold water pipe system based on pipes, a hot water source (a gas or electric heater, or based on solar cells), a source of cold water (a cistern, or tank), a water tank located on a toilet, this deposit can be an additional one already installed on a toilet, and a thermostatic control system.
