Types of valves commonly used in water supply systems

In water supply systems, valves play a key role in controlling and regulating the flow of fluids, and are vital to maintaining the stable operation and safety of the water supply system. According to different water demand and working environment, there are various types of valves on the market. So, in the water supply system, we can usually see what types of valves?

1. ball valves：

• Ball valves are highly regarded for their simple structure and reliable sealing performance. By rotating the holes in the ball, effective control of fluid flow is realized, especially for small and medium-sized pipelines as well as occasions where the flow of fluid needs to be cut off quickly. In water supply systems, ball valves are mostly used in indoor water supply pipelines to ensure that the water supply can be cut off quickly and stably.

2. butterfly valve：

• Butterfly valves are widely used in water supply systems because of their simple structure, light weight and easy operation. These valves regulate the flow of fluid by rotating the circular valve disc, which is especially suitable for pipelines with large flow rate or need to adjust the flow rate. In the field of urban water supply network and industrial water supply, butterfly valves are often used for flow control and pressure regulation.

3. gate valve：

• Gate valves have won wide popularity due to their simple construction and excellent durability. These valves regulate the flow of fluid by moving the gate up and down, and are particularly suitable for larger diameter pipelines and for those scenarios where complete opening or closing is required. In water supply systems, gate valves are usually deployed at the inlet and outlet of pumps as well as on the main pipeline, and their main function is to cut off or connect the water supply and drainage.

4. check valves：

• The main function of the check valve is to prevent the medium from flowing in the reverse direction, thus effectively protecting the pipeline and equipment from damage. In the water supply system, check valves to ensure one-way flow of water to prevent backflow or backwash phenomenon, to ensure stable operation of the system. These valves are usually installed in the outlet of the pump and the intersection of the pipeline, to play its role of security.

5. control valve：

• The main function of this valve is to regulate the flow rate and pressure in order to ensure that the fluid in the water supply system flows as smoothly as required. Regulating valves are particularly critical where precise control of water flow is required, such as in the adjustment of water supply pressure and water quality control systems. Regulating valves are widely used in many fields such as urban construction, industrial water supply and agricultural irrigation.

This paragraph provides a comprehensive overview of valves commonly used in water supply systems. Accurate selection and proper use of valves, not only can significantly improve the operational efficiency and stability of the water supply system, but also to ensure the rational use of water resources and water supply safety.
