In the present application, the first pressure preset value is 0.12MPa, and the second pressure preset value is 0.3MPa, that is, when the inlet pressure of the switching device 400 is reduced from the initial pressure to less than 0.12MPa, the switching device 400 is in the state of turning on the first water dividing pipe 800, and when the inlet pressure of the switching device 400 is increased from the initial pressure to more than 0.3MPa, the switching device 400 is in the state of turning off the first water dividing pipe 800.

In the present application, the flow preset value is 200ml/min, the third pressure preset value is 0.15MPa, and the fourth pressure preset value is 0.11 MPa. When the water flow in the second water diversion pipe 900 is larger than 200ml/min, the dynamic sequence valve 500 is a common sequence valve and has a preferential distribution function; when the pressure difference between the two ends of the dynamic sequence valve 500 is less than 0.11MPa, the dynamic sequence valve 500 disconnects the second water diversion pipe 900, and the switching device 400 is connected with the first water diversion pipe 800 at the moment, and the water purifier 100 preferentially supplies water for the pipeline machine 200; if the pressure difference between both ends of the dynamic sequence valve 500 is greater than 0.15MPa, the dynamic sequence valve 500 turns on the second water distribution pipe 900, and the switching device 400 turns off the first water distribution pipe 800 at this time, the water purifier 100 supplies water to the faucet 600. When the water flow rate of the second water dividing pipe 900 is lower than 200ml/min, the dynamic sequence valve 500 has no priority distribution function, the dynamic sequence valve 500 is a simple connecting pipe, water directly passes through the dynamic sequence valve 500, and the pressure difference between two ends of the dynamic sequence valve 500 is zero. It is understood that, in other embodiments of the present application, the preset flow rate value may also be changed according to a change of an actual water consumption of the pipeline machine 200, for example, the preset flow rate value is 150ml/min, 180ml/min, 220ml/min or 250ml/min, and meanwhile, as the first preset pressure value and the second preset pressure value are changed, the third preset pressure value and the fourth preset pressure value may also be changed accordingly, for example, in the present application, the third preset pressure value may be any value from 0.12MPa to 0.3MPa, which is not limited herein.

According to the waterway structure, the dynamic pressure reducing valve 300 and the switching device 400 are respectively arranged in the first water dividing pipe 800 and the second water dividing pipe 900, when the pipeline machine 200 needs large-flow water supply, the water flow in the water inlet pipe 700 is more than 200ml/min, the inlet pressure of the switching device 400 is also lower than 0.12MPa, the switching device 400 is in an open state, and the system supplies water for the pipeline machine 200 normally; if the faucet 600 is also opened at this time, the pressure at the water outlet of the faucet 600 is zero, the initial flow rate is less than 200ml/min, the dynamic sequence valve 500 is a connecting pipe and provides water with the flow rate less than 200ml/min for the faucet 600, and the pressure of the switching device 400 is reduced, and the system continues to supply water for the pipeline machine 200 normally; when the pipeline machine 200 does not need to supply water, the pressure in the water path continues to rise, and when the pressure is greater than 0.15MPa, the dynamic sequence valve 500 is communicated with the second water distribution pipe 900, and the water faucet 600 supplies water normally; when the water tap 600 also does not require water supply, the pressure of the switching device 400 continues to increase by the water remaining in the water inlet pipe 700 until the switching device 400 disconnects the first water distribution pipe 800. This application can realize when tap 600 all need supply water with pipeline machine 200, preferentially for pipeline machine 200 supplies water to avoid pipeline machine lack of water, the temperature of cup to differ, user experience not good scheduling problem.

In a specific embodiment, referring to fig. 2, a dynamic pressure reducing valve 300 is disposed in the water inlet pipe 700, when the water flow of the water inlet pipe 700 is smaller than a preset flow value, the dynamic pressure reducing valve 300 can allow water to pass through directly, and the pressure difference between two ends of the dynamic pressure reducing valve 300 is zero; the dynamic pressure reducing valve 300 is capable of reducing the water pressure in the water inlet pipe 700 to be lower than a fifth pressure preset value when the water flow rate of the water inlet pipe 700 is greater than the flow preset value, and the fifth pressure preset value is greater than the first pressure preset value and less than the second pressure preset value. That is, when the water flow in the water inlet pipe 700 is greater than 200ml/min, the dynamic pressure reducing valve 300 is a common pressure reducing valve, has a pressure reducing effect, and can reduce the outlet pressure of the dynamic pressure reducing valve 300 to be lower than 0.12-0.3 MPa; when the water flow rate of the water inlet pipe 700 is less than 200ml/min, the dynamic pressure reducing valve 300 has no pressure reducing effect, the dynamic pressure reducing valve 300 is a simple connecting pipe, water directly passes through the dynamic pressure reducing valve 300, and the pressure difference between two ends of the dynamic pressure reducing valve 300 is zero.

In summary, after the dynamic pressure reducing valve 300 is installed in the water inlet pipe 700, when the pipeline machine 200 needs a large flow of water, the water flow rate in the water inlet pipe 700 is greater than 200ml/min, the dynamic pressure reducing valve 300 performs a pressure reducing function, the outlet pressure of the dynamic pressure reducing valve 300 is reduced to be lower than 0.12MPa to 0.3MPa, the inlet pressure of the switch device 400 is also lower than 0.12MPa to 0.3MPa, the switch device 400 is in an open state, and the water pipe normally supplies water to the pipeline machine 200; if the faucet 600 is also opened at this time, the pressure at the water outlet of the faucet 600 is zero, the initial flow rate is less than 200ml/min, the dynamic sequence valve 500 is a connecting pipe and provides water with the flow rate of less than 200ml/min for the faucet 600, the pressure of the switching device 400 is reduced, and the system continues to supply water for the pipeline machine 200 normally; when the pipeline machine 200 does not need to supply water, the pressure in the water path continues to rise, and when the pressure is greater than 0.15MPa, the dynamic sequence valve 500 is communicated with the second water distribution pipe 900, and the water faucet 600 supplies water normally; when the faucet 600 also does not require water supply, the remaining water in the water pipe causes the pressure of the switching device 400 to continuously increase until the switching device 400 disconnects the first water distribution pipe 800. The water supply method and the water supply device can realize that water is preferentially supplied to the pipeline machine 200 when the water faucet 600 and the pipeline machine 200 both need to supply water; meanwhile, when water supply is not needed, the water purifier 100 is closed through the switch device 400, frequent starting of the water purifier 100 is avoided, the service lives of the electromagnetic valve and the water pump in the water purifier 100 are not affected, and meanwhile, due to the fact that the pipeline machine 200 is connected with the water purifier 100 and cut off, the pipeline machine 200 can work more stably.
