Circulating Water Liquid-Controlled Slow-Closing Check Butterfly Valve

Hydraulic Check Valves (Water Circulation)

Circulating Water Liquid-Controlled Slow-Closing Check Butterfly Valve

(1) Scene Problems

1. Harm of Water Hammer Phenomenon: In circulating water systems, when the pump suddenly stops or the direction of water flow changes rapidly, a significant water hammer pressure can be generated. This can damage the piping system and valves, potentially causing serious consequences such as pipe rupture and valve deformation.

2. High Reliability Requirement for Check Function: Circulating water systems require valves to reliably prevent backflow of water to prevent the pump from reversing and protect the safety of the pump and other equipment.

3. Flow Regulation and System Balance Issues: Circulating water systems typically need to regulate water flow according to different operating conditions to achieve system balance and energy-efficient operation. Ordinary check valves cannot meet this requirement.

(2) Shanghai Rogers Butterfly Valve Technology and Features

1. Liquid-Controlled Slow-Closing Function: The valve is equipped with an advanced liquid control system. When the pump stops or there is abnormal water flow, the liquid control system can automatically control the closing speed of the valve plate to achieve slow closing, effectively cushioning water hammer pressure. The closing time of the valve plate can be precisely adjusted according to system requirements, generally within the range of 2 - 10 seconds.

2. Reliable Check Structure: A dual valve plate structure is used, with one main valve plate and one auxiliary valve plate. Under normal water flow conditions, the main valve plate is open and the auxiliary valve plate is closed. When water backflow occurs, the auxiliary valve plate quickly closes, followed by the main valve plate closing under the action of the liquid control system. This double safeguard prevents water backflow.

3. Flow Regulation Function: By adjusting the opening limit device of the valve stem, precise regulation of the circulating water flow can be achieved, meeting the flow requirements of the system under different loads and achieving system balance and energy savings.

(3) Solutions to Pain Points

1. The liquid-controlled slow-closing function effectively addresses the water hammer issue in circulating water systems, protecting the safety of pipes and equipment, and reducing maintenance costs and downtime caused by water hammer.

2. The dual valve plate check structure enhances the reliability of the check function, ensuring that pumps and other equipment are not damaged by backflowing water and safeguarding the normal operation of the system.

3. The flow regulation function allows the circulating water system to flexibly adjust the flow according to actual needs, improving the system's operating efficiency and energy-saving effects, and reducing operating costs.
