What kinds of valves are there for industrial wastewater treatment

Industrial wastewater treatment is a key step in protecting the environment and achieving sustainable development. In this processing procedure, valves, as an important fluid control device, play an indispensable role. The following are some commonly used valves in industrial wastewater treatment and their functions.

First of all, the check valve is one of the common valves in industrial wastewater treatment. Its main function is to prevent wastewater from flowing back during the treatment process and ensure the smooth progress of the treatment process. The check valve achieves opening and closing by utilizing the kinetic energy of the fluid and its own gravity, without the need for external power. Therefore, it features a simple structure and convenient maintenance.

Secondly, control valves are also commonly used valve types in industrial wastewater treatment. The regulating valve achieves precise control of the wastewater flow by changing the gap between the valve core and the valve seat. During the wastewater treatment process, it is necessary to adjust the flow and pressure of the wastewater according to the demands of different treatment stages to ensure the best treatment effect.

In addition, gate valves and butterfly valves are also common valves in industrial wastewater treatment. Gate valves feature low fluid resistance, small opening and closing torque, and unrestricted medium flow direction. They are suitable for applications in wastewater treatment where large flow rates are required. Butterfly valves have the advantages of simple structure, small size, light weight and convenient operation, and are suitable for occasions that require rapid opening and closing in wastewater treatment.

Finally, safety valves are also an indispensable part of industrial wastewater treatment. The main function of a safety valve is to prevent pipelines or equipment from exploding or leaking due to overpressure. During the wastewater treatment process, due to changes in the internal pressure of the treatment equipment, overpressure may occur. At this time, the safety valve can automatically open to release the excess pressure and ensure the safe progress of the treatment process.
