Problems solved by technology
This kind of water supply system will waste a certain amount of water when adjusting the temperature at the beginning of use. At the same time, if the temperature of the hot water is too high, it is easy to partially vaporize when the water is discharged, making it difficult to mix the cold and hot water at the water distribution point, which affects the normal use of the shower.
Public bathrooms are equipped with a large number of showers. Adjacent showers interfere with each other during use, and the dynamic pressure of the water distribution network fluctuates greatly, which will cause the water temperature of the shower water to be unstable.
Due to the characteristics of the use of public bathrooms, the peak and low peak periods of water use alternately occur, which will also cause large fluctuations in the water pressure of the water distribution pipe network. The above problems directly affect the stability and water saving of the system's water supply, reducing its use safety and comfort

A public bathroom dual-pipe hot water constant temperature and pressure supply control system, including more than one shower, the inlet of the shower is connected to the outlet of the thermostatic mixing valve, the cold water and hot water inlets of the thermostatic mixing valve are respectively connected to the cold water pipe network The output connection of the control subsystem and the hot water pipe network control subsystem, the flow and pressure of cold water and hot water are controlled by PLC, and the mixing ratio of cold and hot water can be controlled according to the temperature value set by the shower, so that the water output of the shower The temperature is kept constant all the time, and the invention has the advantages of saving water and energy, convenient use, comfort, safety and the like.
Description
technical field [0001] The invention relates to a water supply control system, in particular to a public bathroom dual-pipe hot water supply control system with constant temperature and pressure. Background technique [0002] In the traditional two-pipe water supply system in public bathrooms, bathers need to manually open the hot and cold water valves of the shower, so that the flowing hot and cold water can be mixed in an appropriate proportion to adjust the water temperature. This kind of water supply system will waste a certain amount of water when adjusting the temperature in the initial stage of use. At the same time, if the temperature of the hot water is too high, it is easy to partially vaporize when the water is discharged, making it difficult to mix the cold and hot water at the water distribution point, which affects the normal use of the shower. Public bathrooms are equipped with a large number of showers. Adjacent showers interfere with each other during use, a...
