The double-handle kitchen faucet's dual-valve independent control mechanism achieves precise coordinated optimization of water temperature and flow through the exquisite coordination of two independent valve core systems and linkage design. This mechanism physically separates the cold and hot water circuits, and each handle corresponds to the independent control of the cold water valve and the hot water valve, allowing the operator to adjust the opening and closing degree of the two valves to separately control the flow of cold water and hot water, thereby achieving precise control of the mixed water outlet temperature and total flow.
From the perspective of control logic, when the two valves operate independently, the flow changes of cold water and hot water show a linear correlation. When the water temperature needs to be adjusted, the mixing ratio of cold and hot water can be changed by fine-tuning the opening and closing degree of one of the valves, while the other valve can maintain a relatively stable flow output to avoid large fluctuations in the total flow due to the adjustment of a single valve. The separate adjustment method of the double handle kitchen faucet breaks the limitation of the mutual restraint of water temperature and flow in single-valve control, allowing the operator to flexibly control the water outlet intensity while pursuing a specific water temperature to meet the water demand in different cooking scenarios.
In practical applications, the mechanical structure design of the dual valve provides hardware support for this precise coordination. The valve core is the control core, and its precise ceramic sealing components or copper valve discs can achieve small angle adjustments to ensure a delicate transition of flow changes. When the two valves are adjusted at the same time, the proportional relationship between their opening and closing angles will be converted into a stable water temperature output through the pressure balance mechanism of the internal water flow channel. For example, when a small flow of warm water is required, the hot water valve can be opened to a smaller angle, and the cold water valve can be opened to a corresponding angle at the same time. The flow ratio of the two is mixed and buffered by the internal water channel to form a small flow of water with a constant temperature; when a large flow of flushing is required, the opening and closing of the two valves can be increased simultaneously to increase the total flow while keeping the water temperature unchanged.
In addition, the independent control mechanism of the dual valve can also achieve dynamic optimization through operational feedback. Since the adjustment force and angle changes of the two handles have a clear corresponding relationship, the operator can form muscle memory through the feel, and gradually master the optimal adjustment combination of water temperature and flow in repeated operations. This optimization process of human-computer interaction makes the dual valve control more and more in line with the user's operating habits in long-term use, further improving accuracy. At the same time, the double valve structure is more adaptable to water pressure changes. When the water inlet pressure fluctuates, the two valves can be adjusted through their respective valve core resistances for buffering, reducing the sudden flow changes caused by pressure changes in a single valve, thereby maintaining the relative stability of water temperature and flow.
The double valve independent control mechanism of the double handle kitchen faucet achieves precise coordination of water temperature and flow through physically separated water channel control, precise valve core adjustment, proportional balance of water flow mixing, and human-computer interaction operation optimization, providing a more flexible, stable and efficient control experience for kitchen water use.
