Water tank water inlet system with double-protection function

The utility model relates to a water tank water inlet system with a double-protection function. The water tank water inlet system comprises a water tank, a liquid level meter, a main electric water inlet valve, a standby pipeline, a remote control floating ball valve arranged on the standby pipeline, an electromagnetic valve, a floating ball valve, a common pipeline and a second floating ball valve arranged on the common pipeline. According to the utility model, the common pipeline is matched with the standby pipeline, and the common pipeline of which the water inlet capacity is less than or equal to the pollution discharge capacity in the pump room is selected, so that the problems of water shortage and overflow possibly caused by the fault of the water inlet pipeline of the clean water tank can be solved simultaneously, and the water supply continuity and safety of the water pump room are effectively improved. 本实用新型涉及一种具双保护功能的水箱进水系统，包括：水箱，液位计，总电动进水阀门，备用管道，设置于备用管道的遥控浮球阀，电磁阀，浮球阀，常用管道，设置于常用管道的第二浮球阀。本实用新型通过常用管道
