In water supply systems, valves are used to control and regulate the flow of water in pipes. Properly installed valves not only ensure the normal operation of the water supply system, but also facilitate maintenance and repairs. The following will introduce the installation locations and common types of water supply pipeline valves.
1. Installation location
1. Main pipe entrance: The main pipe entrance is an important control node of the water supply system, and a main valve is usually installed. The main valve is used to close or open the entire water supply system for maintenance, inspection, or water outage in emergency situations.
2. Branch pipe entrance: The branch pipe entrance is the secondary control node of the water supply system, and a branch valve is usually installed. Branch valves are used to control the water flow of each branch pipe to facilitate the regulation and control of water supply in different areas.
3. Floor water inlet pipe: In multi-story buildings, each floor usually has a water inlet pipe. On the water inlet pipe of each floor, a floor valve needs to be installed to control the water supply to that floor.
4. Pipes inside the room: Pipes inside the room are usually equipped with some small valves to control the flow of water in the room. For example, bathrooms, kitchens, toilets and other rooms will have corresponding valves to facilitate the control of water supply in specific areas.
2. Introduction to valve types
1. Globe valve: Globe valve is one of the most common types of valves. It is mainly used to completely open or close the flow of water in a pipe. The stop valve has a simple structure and is easy to use, and is widely used in various water supply systems.
2. Throttle valve: Throttle valve is used to regulate the flow of water in the pipeline. It controls the water flow by changing the opening of the valve. Throttle valves are mostly used in situations where precise control of water flow is required, such as laboratories and medical equipment.
3. Positioning valve: A positioning valve is a valve that can be positioned at a specific position. It can be turned on or off at specific locations on the pipe to facilitate control of the water supply to a certain area.
4. Automatic valve: An automatic valve is a valve that can automatically open or close based on the water pressure or water level in the pipeline. It is often used in automated control systems to automatically adjust water supply based on demand.
5. Electric valve: An electric valve is a valve driven by an electric motor. It can be controlled by remote control or automation system to realize remote adjustment and control of water supply pipelines.
The above is an introduction to the installation locations and common types of water supply pipeline valves. Different installation positions and types of valves play different roles in the water supply system, ensuring the normal operation and flexible control of the water supply system.
