Large-diameter check valve, also known as large-diameter silent check valve, adopts the contour design in line with hydraulics to obtain a better streamlined water path. The design of internal attachment to the fluid can ensure that Z small pressure loss silent check valve is installed at the water outlet of the pump, and can be quickly closed before the water flow reverses to avoid water hammer, water hammer sound and destructive impact, so as to achieve the purpose of silence, prevent backflow and protect the equipment.
Large-diameter check valves are widely used in large-scale water supply and drainage, fire protection, HVAC, industrial and other systems and pipelines, as well as urban construction, chemical, metallurgy, petroleum, food, beverage, environmental protection and other industries. Its main feature is that it is generally installed at the outlet of a large water pump, and can be closed quickly before the water flow reverses to avoid water hammer, water hammer sound and destructive impact, so as to achieve the purpose of silence, preventing media backflow and protecting equipment.
