Referring to FIGS. 1 and 4 , a tank dual-level control device according to an embodiment of the present invention includes a tank 100 , an auxiliary float valve 200 , and a remote-controlled float valve 300 .

The top of the pool 100 is open, one side of the pool 100 is connected with a main water inlet pipe 110 , and the lower part of the pool 100 is connected with a water outlet pipe 120 .

The auxiliary float valve 200 is placed in the pool 100, and is connected with an auxiliary water inlet pipe 210. The flow rate of the auxiliary water inlet pipe 210 is smaller than the flow rate of the main water inlet pipe 110. Replenish water within 100.

The remote control float valve 300 includes a main valve 310 and a main float pilot valve 320. The main valve 310 is arranged on the main water inlet pipe 110. The main float pilot valve 320 is placed in the pool 100 and below the auxiliary float valve 200. The valve 320 is communicated with the main valve 310 through the floating ball conduit 321. The opening and closing of the main floating ball pilot valve 320 can control the opening and closing of the main valve 310.

After the water level is higher than the water storage protection level 410, the main float pilot valve 320 is closed, so that the main valve 310 is also closed, and the main valve 310 stops supplying water to the pool 100. The float valve 200 remains open, and the auxiliary water inlet pipe 210 replenishes water until the water level returns to the high water storage level 400, the auxiliary float valve 200 is closed, and the water in the pool 100 is stored for the next peak water consumption period.

The auxiliary float valve 200 and the remote control float valve 300 are used together, so that the pool 100 can automatically adjust the water storage capacity in the pool 100 during the peak water consumption period to meet the water demand of the user; after entering the normal and low period, the auxiliary float valve 200 continues to replenish water, The pool 100 is filled with water to realize the storage during low peak hours, so that the pool 100 realizes the adjustment and storage function of "cutting peaks and filling valleys". The main float pilot valve 320 is submerged in water most of the time and remains closed, and only opens when the water level drops to the water storage guarantee level 410, which reduces the running time of the remote control float valve 300 and avoids the frequent opening and closing of the main valve 310, thereby prolonging the main float valve.
