Detailed ways

As shown in Figure 1, the utility model box-type stacked water supply equipment includes a water purification cycle controller 2, a stainless steel water tank 5, a water pump 9, a frequency conversion control cabinet 14, and a voltage stabilizing tank 13;

The input end of the water purification cycle controller 2 is connected to the municipal tap water pipe network 1, and the output end of the water purification cycle controller 2 is connected to the stainless steel water tank 5 through the water tank inlet pipe 16, and the water tank inlet pipe 16 is provided with a pressure transmitter 3; the stainless steel water tank 5 is provided with a remote control float control valve 4, and the remote control float control valve 4 is used to control the water level of the water tank to prevent overflow;

The water tank outlet pipe 7 of the stainless steel water tank 5 is respectively connected to the input end of no less than one water pump 9 through the water pump inlet pipe 8, and the output ends of all the water pumps 9 are respectively connected to the water pump outlet pipe 12, and the water pump outlet pipe 12 is connected to the user pipeline; the water pump outlet pipe 12 A pressure-stabilizing tank 13 is arranged on the top; a water outlet pressure sensor 11 is also arranged on the outlet pipe 12 of the water pump;

A steady flow compensator 6 is connected between the stainless steel water tank 5 and the water inlet pipe 8 of the water pump through a pipeline;

The water pump inlet pipe 8 and the water pump outlet pipe 12 are connected through a direct water supply bypass pipe 15, and a check valve 10 is arranged on the direct water supply bypass pipe 15;

The pressure transmitter 3, the water pump 9, and the water outlet pressure sensor 11 are respectively connected with the frequency conversion control cabinet 14 through wires to form a control system.

In practical application, a protection value is set for the municipal tap water pipe network 1. This protection value is the critical value that may generate negative pressure on the pipe network when the pressure of the municipal tap water pipe network 1 drops and the incoming water is less than the water demand. This value is monitored by pressure transmitter 3 .

When the pressure of the municipal tap water pipe network 1 is normal, the stainless steel water tank 5 is filled while the municipal tap water pipe network 1 is supplying water to users; The demand is superimposed on the pressure water supply, and the pressure is added according to the principle of how much the difference is, so as to save energy.

If the water supply pressure of the municipal tap water pipe network 1 can directly meet the needs of users, the water pump 9 stops running, and water is directly supplied through the direct water supply bypass pipe 15 .

When the control system receives the signal from the pressure transmitter 3 that the pressure of the municipal tap water pipe network 1 is lower than the protection value, the equipment uses the water stored in the stainless steel water tank 5 to compensate the water supply to the user, and at the same time, the steady flow compensator 6 is automatically opened , carry out steady flow compensation according to the system demand, make up as much as the difference, eliminate the generation of negative pressure, and ensure the continuous water supply to the user; after the compensation is completed, return to the normal water supply mode.

At night and in the case of low-flow users, the water pump 9 does not need to be started, and the pressure of the water supply at the user end is maintained by the surge tank 13 .

The water purification cycle controller 2 controls the equipment to supply the water stored in the stainless steel water tank 5 to the user regularly according to the set time, to ensure that the water in the stainless steel water tank 5 is updated at least once a day, to keep the water quality clean and hygienic, and to prevent the municipal water supply pressure from meeting the requirements. When needed, the water stored in the stainless steel water tank 5 deteriorates.

The above is only an embodiment of a box-type laminated water supply device that does not generate negative pressure involved in the present invention, and is not intended to limit the scope of protection of the present invention.
