The beneficial effects of the utility model are: adopt frequency conversion drive, decrease power consumption, and use wireless senser that wiring is significantly reduced, can regulate hot water supply water temperature by arranging electrically operated valve, the utility model can realize stable constant pressure water supply.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model constant pressure water supply device.
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing, make above-mentioned and other object of the present utility model, Characteristics and advantages will be more clear.Reference numeral identical in whole accompanying drawing indicates identical part.Deliberately do not draw accompanying drawing in proportion, focus on purport of the present utility model is shown.
As shown in Figure 1, constant pressure water supply device of the present utility model comprises the building 1 with cold water supplying pipe road 2 and hot water feeding pipe road 3, described cold water supplying pipe road 2 is connected with the delivery port of the first supply-water pump 4, described hot water feeding pipe road 3 is connected with the second supply-water pump 5, the delivery port of described first supply-water pump 4 is also connected with described second supply-water pump 5 by connecting pipe, described connecting pipe is provided with electrically operated valve 6, the water inlet of described first supply-water pump 4 connects cold water pipe, the water inlet of described second supply-water pump 5 connects hot-water line, the top in described cold water supplying pipe road 2 is provided with the first wireless pressure sensor 13, the top in described hot water feeding pipe road 3 is provided with the second wireless pressure sensor 14 and radio temperature sensor 15, described first supply-water pump 4 is electrically connected with PLC9 by the first frequency converter 7, described second supply-water pump 5 is electrically connected with described PLC9 by the second frequency converter 8, the output of described PLC9 is connected with described electrically operated valve 6, and described PLC9 is also connected with touch-screen 10, supervisory control comuter 12 and wireless communication unit 11 respectively.
The utility model by the first supply-water pump 4 and the second supply-water pump 5 for building 1 provides hot and cold water, pressure sensor is provided with respectively on the top in cold water supplying pipe road 2 and the top in hot water feeding pipe road 2, pressure due to pipeline top is minimum, therefore detect that pipeline top pressure reaches after setting requires and then can ensure that other position pressure of supply water of building can reach setting requirement, equally because hot water pipeline top water temperature is minimum, therefore the temperature pick up 15 by being arranged at top detects that temperature reaches after setting requires then can ensure that other position of building hot water temperature can reach setting requirement, wireless senser is adopted to reduce wiring, this is very favourable for high-rise or super high rise building, first wireless pressure sensor 13, second wireless pressure sensor 14, with the pressure and temperature value detected between radio temperature sensor 15 sends to PLC9 by wireless communication unit 11, the force value detected compares with setting value by PLC9, when detected value is lower than setting value, the rotating speed of the first supply-water pump 4 and the second supply-water pump 5 is then adjusted respectively by the first frequency converter 7 and the second frequency converter 8, thus keep pressure of supply water in cold water supplying pipe road 2 and hot water feeding pipe road 3 constant, hot water feeding pipe road water temperature can be regulated by the aperture adjusting electrically operated valve 8, detect hot water supply water temperature higher than during setting value then PLC9 drive electrically operated valve run to positive direction, open large valve opening, more cold water is made to enter hot water feeding pipe road thus reduce water temperature like this, otherwise when water temperature is lower than setting value, then PLC9 reduces the aperture of electrically operated valve 6.Can adjust the setup parameter of PLC9 by being arranged at on-the-spot touch-screen 10, supervisory control comuter 12 can real time remote display water supply condition.
Set forth a lot of detail in the above description so that fully understand the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be much different from alternate manner described here to implement, and therefore the utility model is not by the disclosed concrete restriction implemented above.Any those skilled in the art are not departing under technical solutions of the utility model ambit simultaneously, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Every content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model protection.
