The water level of the fire water tank, how to replenish the water in the stainless steel fire water tank?

Feb 17, 2023

The water level of the fire water tank is designed at the beginning of the design of the water tank. For example, the water level of a water tank with a height of 2 meters is generally designed at about 1.6 meters. The distance from the top of the water tank is generally about 30-40CM, and there will be a small gap according to different needs.

Secondly, the water level of the fire water tank is generally higher than the water level of the water inlet, and the control of the water level is controlled by a liquid level gauge or a float valve to meet the effective water level standard. An overflow (full water level) is also designed on the fire water tank. The purpose of designing this hole is that when the water inlet level control fails, the water will naturally flow out from the overflow hole and be discharged into the drain. Avoid flooding around the fire water tank.


So how is the replenishment of the fire water tank completed?

The water replenishment of the fire water tank is also controlled by the liquid level control or the float ball, and the water replenishment work is completed automatically. For example, the liquid level control is completed by the liquid level sensor. When the water level is lower than the set water shortage level, the sensor transmits the water shortage information to the control system, and the control system sends an instruction to open the water inlet electric valve for automatic water replenishment. When the water level reaches the high water level Automatic stop.

The control of the float valve is much simpler, because the float changes according to the liquid level, and the water level is sensed by the float installed in the water tank. When the water level rises to the highest water level, the floating ball floats up, and the water inlet valve is closed by utilizing the buoyancy of the floating ball. Therefore, the water level of the fire water tank can always be kept at an effective high water level.

Both methods are systems for controlling the replenishment of fire water tanks, and the one that suits you should be used according to different needs. The advantage of the first type of liquid level sensor is that it can transmit the water level data to the fire control system or control room in real time; the installation and maintenance of the second type are relatively simple and low in cost. If you purchase the second solution, it is recommended to use a remote control float valve for control, which is the best way to stabilize performance since we have used it.
