Strainers are devices that are used to separate solid particles from liquid or gas. They are a type of control device that is commonly used in industrial processes, HVAC systems, and water treatment plants. Strainers work by trapping particles that are too large to pass through the openings in the strainer mesh or screen, while allowing the liquid or gas to flow through.
There are different types of strainers available, including Y-strainers, basket strainers, and duplex strainers. Y-strainers are named after their shape and are typically used in applications where space is limited. They are designed to remove small particles and debris from liquids or gases. Basket strainers, on the other hand, are larger and can handle higher flow rates. They are used in applications where larger particles need to be removed from the liquid or gas. Duplex strainers are used in applications where continuous operation is required, as they can be cleaned while the other strainer is in use.
Strainers are an important part of many industrial processes and are used to protect equipment such as pumps, compressors, and valves from damage caused by particles in the fluid or gas. They are also used in HVAC systems to prevent particles from entering the ductwork and causing damage to the system or reducing air quality. In water treatment plants, strainers are used to remove larger particles and debris before the water enters the treatment process.
