Description
Technical Field
The invention relates to water inlet control equipment of a water tank, in particular to a water inlet control device of an emergency water tank.
Background
At present, the water inlet of the water tank is generally controlled automatically by a purely mechanical float valve. The control principle is as follows: the switch of the valve is controlled by the floating ball, the floating ball changes along with the change of the liquid level of the water tank, and when the liquid level of the water tank drops, the valve is gradually opened; when the water tank liquid level reaches the highest liquid level of the floating ball, the valve is closed.
The water inlet mode of the control water tank is completely dependent on the floating ball, foreign matters often occur to block the floating ball, or the floating ball valve fails, and even if the liquid level of the water tank reaches the highest liquid level of the floating ball, the valve cannot be closed, so that a large amount of water overflows from the water tank to cause flooding of a pump house. Accidents of flooding of the pump house due to cracking of pipelines or water tanks in the pump house also often occur. Some pump rooms adopt a pump room water leakage sensor to detect water leakage, and once the pump room is water-filled, an inlet electric valve is closed to cut off water inflow. However, the fact is that the water leakage condition mostly occurs when the pump house fails, no power supply exists, the electric valve cannot be closed in time, only manual detection can be performed to close the inlet valve, water is often accumulated deeply at the moment, a large amount of water flooding of the whole pump house is caused, all equipment is scrapped, great economic loss is caused, and the condition frequently occurs from the pump house maintenance history of more than ten years.
