What are the valves used for water supply and drainage pipes

Water supply and drainage pipelines are mainly used for water supply pipelines, and in order to make water supply pipelines better meet the needs of users, valves play a role that cannot be ignored. Next, we will introduce the main valves commonly used in water supply pipelines.

Butterfly valve: Butterfly valve is a kind of control valve with simple structure, and it is also a kind of valve commonly used in the water supply pipeline. It generally plays the role of cutting off and intercepting in the water supply pipeline. The advantages of butterfly valve are small size, light weight, so easy to install and operate; This valve also opens and closes very quickly with low flow resistance.

Gate valve: The gate valve is mainly used to cut off the flow of water in the water supply pipeline, suitable for use in the water supply pipeline that needs to be opened or closed frequently. The gate valve can realize the bidirectional flow of water in the feed pipe; In the fully open state, the erosion is less than the stop valve. Gate valves can be divided into parallel plate gate valve, wedge gate valve, gate valve and other types.

Globe valve: The valve is a one-way valve, compared with the gate valve, its structure and maintenance are simple. Because the opening or closing stroke of the stem of the globe valve is relatively short, the globe valve has a very reliable cut-off function; Its wear resistance and high temperature performance are more prominent; Globe valves are ideal for cutting off and regulating water flow in water supply lines.

Check valve: Check valve is also called check valve, check valve or back pressure valve. This valve is an automatic valve, usually relying on the flow of water in the feed line itself to generate force, so as to open and close automatically. In the feed line when the stop return valve is mainly used to prevent water backflow.
