[0029] Two parallel water supply branches are additionally arranged on the original water supply valve group, one is the float ball valve water supply branch 2, and the other is the standby water supply branch 3; the float ball valve water supply branch 2 is connected with the water supply main pipeline 4 through the second double ball valve 13, so that the opening and closing of the new water supply branch can be controlled, and it is ensured that the water tank can still continuously obtain water when the electric valve water supply branch fails; in the same way, the standby water supply branch 3 is also connected with the water supply main pipeline 4 through the third double ball valve 16, and a 90-degree elbow connecting pipe is arranged at the end; the purpose of the branch pipe is to use manpower to connect the hose when the two water supply pipelines fail simultaneously, and to supply water to the water tank of the washing tower;

[0030] The pipe fitting of the branch pipe where the float ball valve 5 is arranged can be made of UPVC material and is connected with the water tank through flanges; the float ball valve 5 is connected with the straight pipe in the water tank through a direct head, and the valve can automatically adjust the opening and closing state according to the water level in the water tank, so that the water level in the water tank can always be maintained within a reasonable range;

[0031] The working principle of the float ball valve 5 is as follows: when the water surface of the water tank falls, the float in the valve sinks, the pilot hole of the valve body is opened under the action of water pressure, the sealing surface of the control valve is opened, and water flows out from the control valve; when the water surface rises, the float in the valve rises, and when the float rises to a certain position, the lever drives the piston pad to stop water inflow; the second double ball valve 13 of the branch pipe where the float ball valve 5 is arranged should be kept in a closed state and is opened when the electric valve fails;

[0032] Material advantages: the water supply pipeline and the float ball valve 5 can be made of UPVC / PP material, do not release harmful substances, have delicate and smooth appearance, are wear-resistant and resistant to strong acid and strong alkali corrosion, thereby reducing the frequency of replacement and maintenance, reducing operation cost and natural loss of materials;

[0033] Automatic water level adjustment: the float ball valve 5 can automatically adjust the opening and closing state according to the water level in the water tank, so that the water level in the water tank can always be maintained within a reasonable range;

[0034] Improve water supply efficiency: by opening the second double ball valve 13 of the branch pipe where the float ball valve 5 is arranged, the float ball valve 5 can quickly respond to water level changes and timely supplement the required water volume, avoid stopping water supply due to electric valve failure, and improve water supply efficiency;

[0035] Save energy: since the float ball valve 5 can accurately control the water level, energy waste caused by excessive water supply or insufficient water supply is avoided, which is helpful to realize energy saving and emission reduction;

[0036] Reduce cost: the automatic adjusting function of the float ball valve 5 not only improves the stability of the water replenishing system, but also saves the labor cost of manual water replenishing, and further reduces the overall operation cost;

[0037] Easy to install and dismount: the float ball valve 5 has simple and clear structure design and low cost; both of the float ball valves can be connected by loose joint, and can be easily dismounted, so that the maintenance is convenient, and the maintenance difficulty and cost of the system are greatly reduced;

[0038] The float ball valve 5 adopts the upper water inlet design, the float and the water outlet are both at the bottom end of the float ball valve, and the structure is simple and clear; the material can be UPVC / PP, which is resistant to strong acid and strong alkali corrosion, anti-aging and reduces the loss; before installation, the height of the inlet of the water replenishing valve group needs to be set in advance, so that the bottom end of the float ball valve is slightly lower than the high liquid level line of the water tank, so as to automatically stop water replenishing when the water level approaches the high liquid level; then, the external thread water inlet of the float ball valve 5 is precisely aligned and screwed with the water inlet pipe of the water tank, and if necessary, the raw material belt can be wound around the threaded connection; in order to further optimize the water quality, if necessary, a small filter screen can be added in the pipeline between the water inlet of the water tank and the float ball valve, so that the water flow is simply filtered.

[0039] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of the technical features.
