Desarrollo de un dispositivo regulador de flujo de agua hidromecánico para duchas eléctricas domiciliarias.

Abstract

The present research was carried out to develop a device for regulating the flow of hydro-mechanical water for electric showers; the water is the most used resource on the planet and also the worst use is given, being one of the most common forms of waste cleaning, to minimize gas and to be more efficient in its use and because in Ecuador, there is the attempt to eliminate the subsidy of the domestic gas that is used in the heating of water by heating, the idea arises of that intends to save water during the bath as in the future they will have greater demand in the market, the constituent parts of the flow regulator were established by the test and error method, in terms of the fixed parts (carcasses, regulating star and hub), the 3D printing technique was used with ABS (Acrylonitrile, Butadiene, Styrene), material that has water resistance, while the flexible part (O-ring) was made of silicone and nitrile. For the experimentation two operating systems were installed; first one where the water pass valve only controller the branch of the shower and a second one with the pass valve controlling the two branches both the shower and the toilet, parameters were set for valve opening degrees for both the shower as for the toilet, and strategically placed pressure and temperature gauges. Therefore, a functional water flow regulator is used with the use of silicone O-ring at a 24-degree water-outlet valve opening, resulting in a water saving of 33.7% at a flow rate of 2.05 l/min and a comfort temperature of 42°C, it is recommended to have a maximum opening of the toilet valve al 10 degrees, so that the temperature does not change during the shower.
