Abstract

The invention relates to the technical field of flow control devices, and particularly relates to a stable flow accurate control device based on liquid level pressure difference, which comprises a liquid storage tank, wherein a water outlet is formed in the bottom of the liquid storage tank; a water supply system of the water storage tank, and a liquid level adjusting device of the water storage tank; the liquid level adjusting device of the water storage tank is used for adjusting the target height of the water stored in the liquid storage tank, and the water supply system is used for supplying water to the target height in the liquid storage tank; the water outlet is connected with a water outlet pipe, and the water outlet pipe is provided with a bent pipe section; the water supply system comprises a water pump, a control device and a floating ball switch, wherein the control device is in signal connection with the water pump and the floating ball switch; the control device is used for controlling the opening and closing of the water pump according to the signal of the floating ball switch, and the water level adjusting device of the water storage tank adjusts the target height of the water supply of the water supply system by adjusting the height of the floating ball switch. The stable flow accurate control device based on the liquid level pressure difference can solve the problems of easy blockage, high cost and large damage to the water pump in the prior art.

Description

technical field [0001] The invention relates to the technical field of flow control devices, in particular to a stable flow precision control device based on liquid level pressure difference. Background technique [0002] In chemical plants or sewage treatment plants, it is necessary to control the flow of liquid in some scenarios. Usually, electronic flowmeters are used to control the flow of liquid. Although ordinary electronic flowmeters can control the flow more accurately, they also There are many defects, such as: due to the complex internal structure of the electronic flowmeter, it is prone to clogging when transporting liquids with high density and impurities such as sewage or chemical water, and the relatively high cost of the electronic flowmeter, the flowmeter control The flow range is narrow. At the same time, during the water supply process of the water pump, due to the limitation of the flow by the electronic flowmeter, the water pump is in a high-pressure stat...
