Specific functions of check valves

Check valve is a key equipment to prevent fluid backflow in pipeline system, which is crucial to ensure the safe and stable operation of the system. Its core role includes: effectively preventing the reverse flow of fluids, significantly reducing pipeline pressure loss, protecting equipment from damage caused by pressure fluctuations, and helping to save energy and reduce emissions. Reasonable application of check valves can enhance system efficiency, safety and economic and environmental benefits.

Types of valves commonly used in water supply systems

This article analyzes the water supply system five core valve types and applications: ball valves (reliable sealing, fast opening and closing, suitable for small and medium-sized pipeline cut-off); butterfly valves (lightweight and easy to operate, the main control of large flow regulation); gate valves (durable full diameter, used for the main pipeline opening and closing); check valves (to prevent the medium from backing up, to protect the safety of water pumps); regulating valves (accurate control of the flow control pressure, adapt to the precision of the water supply scenarios). Scientific selection can improve system efficiency and water supply safety.

What common types of drain valves include

This article takes a look at the common types of sewage valves and their application scenarios: gate valves (low flow resistance, suitable for large flows of solids-containing wastewater); butterfly valves (compact, lightweight and quick to operate, suitable for wastewater treatment); ball valves (excellent sealing, low flow resistance, suitable for viscous/crystallized media); check valves (to prevent backflow and safeguard pipeline safety); and regulating valves (to control the flow rate/pressure accurately for complex wastewater). Selection should be based on the combination of fluid characteristics (temperature/pressure/chemical composition/solid particles), piping size, and operation and maintenance, in order to enhance the efficiency of wastewater discharge and environmental safety.

Types of valves commonly used in building water supply system

This article introduces the six commonly used valves and their functions in the building water supply system: ball valves (easy to operate, open and close quickly for hot and cold water pipelines), butterfly valves (compact structure, suitable for large flow mains), globe valves (low fluid resistance, adjustable flow), check valves (to prevent backflow, to protect the pumps), regulating valves (to accurately control the flow rate) and pressure reducing valves (to reduce the pressure, to protect the safety of equipment). Engineers need to choose the right valve according to system requirements, operating characteristics and environmental factors to ensure efficient and stable operation of the system.

Types of check valves and their application areas in detail

Check valves are key components to prevent backflow of fluids and ensure stable operation of industrial and civil fluid systems. The main types include swing-open (single, double, multi-valve) and lift-open (vertical, horizontal), which are suitable for different pipe sizes and flow rate scenarios. Materials such as cast iron, cast steel and stainless steel offer a wide range of options to meet corrosion, pressure and temperature requirements.
