This device overcomes the disadvantages of the above two devices. As shown in the figure, when the foot switch water device 1 pulls the valve stem 2 down, the rubber film 3 is turned on with cold and hot water, and the cold and hot water valves can be used to adjust the water temperature. When people leave the foot switch, the diaphragm valve closes with cold and hot water, so that the turbulence of the water will not be caused by the unequal cold and hot water pressure. Although the valve is repeatedly opened and closed, the original adjusted water temperature remains unchanged, allowing the shower to adjust the water temperature and save water and energy with the switch.
Second, economic benefits and features:
1. Compared with cold and hot water double-pipe showers, the device can save more than 30% of water and save energy, and the average annual water-saving per device is 150-300T, saving about 105-3T, and the investment recovery period is less than one year.
2. Compared with the hot water shower, this device has good performance, simple operation and management, and investment.
3, large pedals, small force switch, comfortable to use.
4. The upper and lower valve bodies are isolated by the rubber membrane and the lower valve body is free from water leakage. The cold and hot water valves only function as fine adjustments and are not easily damaged.
5, simple structure, long service life, easy maintenance.
