The key role of butterfly valves in water treatment systems: ensuring stable water quality and water level

In the complex and delicate field of water treatment, every link is crucial, especially the stable control of water quality and water level, which is directly related to the operating efficiency and water quality of the entire system. As an important part of the water treatment system, butterfly valves play an irreplaceable role in key parts such as sedimentation tanks, filtration units, and clear water tanks with their unique structure and superior performance.

1. Basic characteristics and working principle of butterfly valves
Butterfly valves are a type of valve with compact structure, light weight, and easy operation. They are mainly composed of valve body, valve disc (butterfly plate), valve shaft and drive device. Its working principle is to control the flow and cutoff of the medium by rotating the valve disc, and the rotation angle is generally 0° to 90°. The butterfly valve not only has excellent fluid control capabilities, but also can be opened and closed quickly in a small space, which is very suitable for occasions that require frequent operation. In addition, the butterfly valve is made of a variety of materials, including metal, rubber lining, etc., which can adapt to different media and temperature conditions and meet the special requirements of water treatment systems for corrosion resistance and wear resistance.

2. Application of butterfly valve in sedimentation tank
The sedimentation tank is an important link in the water treatment system to remove suspended matter. The application of butterfly valve here is mainly reflected in two aspects: first, by accurately adjusting the water inlet flow rate and controlling the water flow rate, the suspended matter can be fully settled and the sedimentation efficiency can be improved; second, by adjusting the opening of the water outlet, the water pressure inside and outside the sedimentation tank is balanced to prevent the sediment from being re-suspended due to the excessively fast water flow, so as to ensure that the outlet water is clear and transparent and meets the water quality standards. The rapid response and precise control characteristics of the butterfly valve optimize the sedimentation process and greatly improve the efficiency and quality of water treatment.

3. The role of butterfly valve in the filter unit
The filter unit is a key step to further remove tiny particles and impurities in the water. The application of butterfly valve here is mainly reflected in the precise regulation of flow. By adjusting the opening of the butterfly valve, the water flow rate entering the filter can be accurately controlled to avoid excessive flow rate from scouring the filter material and affecting the filtering effect. At the same time, the butterfly valve can also be quickly closed when needed to realize the backwashing operation of the filter, clear the blockage, restore the filtering capacity, and ensure the continuous and efficient operation of the filter unit.

4. Water level control of butterfly valve in clear water tank
As the final storage link of the water treatment system, the stability of the water level in the clear water tank is directly related to the continuity and stability of the subsequent water supply or discharge. The butterfly valve can automatically adjust the opening of the butterfly valve in the outlet pipe according to the preset upper and lower limits of the water level through the integrated water level control system to achieve precise control of the water level. When the water level rises above the upper limit, the butterfly valve automatically opens to increase the water output and prevent overflow; when the water level drops to the lower limit, the butterfly valve automatically closes to reduce the water output and maintain the water level stable. This process does not require manual intervention, which greatly improves the automation level and operation efficiency of the system.

The butterfly valve plays an indispensable role in the water treatment system with its unique structural advantages, precise flow control capabilities and high level of automation. It not only optimizes the sedimentation effect and ensures that the water quality meets the standards, but also maintains the stability of the water level by automatically adjusting the water output, providing a solid guarantee for the continuity and reliability of the water treatment system. With the advancement of technology and the deepening of application, butterfly valves will show broader application prospects in the field of water treatment in the future, and promote the development of water treatment technology in a more efficient and intelligent direction.
