Manufacturers Introduce the Multi-functional Water Pump Control Valve

   The Multi-functional Pump Control Valve is a valve that integrates various control functions, primarily used for flow control at the pump outlet and the elimination of water hammer. It consists of the main valve, regulating valve, and a connection system.

Utilizing a DC valve body design, the main valve control chamber features a dual-control structure with a diaphragm or piston type. This design enables the multi-functional pump control valve to gradually open the pump outlet.

Full-open, slow-close, and cutoff functionalities, all achievable with a single adjustment, enabling a variety of control tasks. The multi-functional pump control valve not only offers the flow control capabilities of a standard valve,‌

The integrated features include gate valves, check valves, and water hammer eliminators.

Working Principle

       Once the pump starts, the water pressure acts on the bottom of the main valve disc and the lower chamber of the control room. This pressure causes the main valve to open, and the water in the upper chamber of the control room is slowly drained to the outlet end through valve B, as the main valve gradually opens.

Adjusting the valve opening provides an appropriate main valve opening speed. After the pump stops operating, the water pressure at the inlet rapidly drops, and under the influence of its own weight and spring pressure, the valve closes most of its opening quickly, preventing

The remaining opening of the backflow is gradually closed under the combined action of the water pressure in the upper chamber of the control room and the water pressure in the lower chamber, with the closing speed slowed to form a buffer, preventing a sudden increase in pressure. Set the opening and adjustment of valves A and B.

Bico achieves the appropriate valve opening and closing speed.

‌The advantages of multi-functional pump control valves mainly include the following aspects:

 High safety and reliabilityThe multi-functional water pump control valve features three anti-water hammer measures: rapid closure, slow closure, and energy-absorbing cavity. It operates in a连锁 manner, preventing any erroneous actions, and effectively prevents accidents caused by the rise in water hammer pressure waves.

2. No Operation Control NeededThe pump features an automatic opening and closing function that utilizes the pressure difference before and after the valve during pump start-up and shutdown, without requiring external control operations.

  3. No Professional Tuning RequiredValve operation is unaffected by variations in liquid level difference, outlet pressure, and pump flow rate, offering a wide range of adaptability and requiring no professional adjustment.

   4. Significant Energy-Saving EffectThe streamlined, wide valve body design reduces resistance loss by over 50% compared to similar foreign products, effectively cutting down energy loss during throttling and achieving significant energy-saving results.

   5. Versatility:The multi-functional pump control valve integrates various functions, including start/stop control, pressure regulation, flow rate adjustment, and dry run protection, catering to the needs of different operating conditions.

Offer control and protection features for pumps.

 ‌7. Automation ControlUtilizing cutting-edge automation control technology, the system can achieve automatic startup and shutdown, automatic adjustment, and automatic protection functions, reducing the need for manual intervention and operation.

8. Stability and ReliabilityUtilizing high-quality materials and advanced manufacturing techniques, the pumps offer excellent durability and stability, ensuring stable operation and guaranteeing the reliability and stability of the system.

  9. Energy-saving and EfficientThrough intelligent control and optimization, it achieves energy-efficient and high-performance pump operation, adjusting the pump's working parameters based on actual needs, thus avoiding energy waste and unnecessary operation.

The application scope of the multi-functional pump control valve is extremely wide, encompassing the following aspects:

  2. Hot Water Heating SystemIn a hot water heating system, the multi-functional pump control valve can optimize system operation efficiency and reduce energy waste by regulating flow and pressure.

3. Fire Protection System:The use of multi-functional water pump control valves in fire systems ensures stable water pressure and rapid response to extinguishing needs during emergencies.

4. High-Rise Building Water Supply SystemIn high-rise buildings, the multi-functional pump control valve effectively prevents water hammer phenomena, safeguarding the pump and pipeline system, ensuring safe water supply.

5. Other Water Supply Systems:In addition to the aforementioned systems, multi-functional pump control valves are widely used in sectors such as municipal, steel, metallurgy, petroleum, chemical, food, and power stations.

Prevent medium backflow, water hammer, and water impact phenomena, enhancing the system's safety and reliability.

Multi-functional pump control valveInstallation Precautions

 Determine the installation location:Pump control valves should be installed close to the pump outlet to minimize water hammer and air hammer phenomena in the pipeline. They should be mounted at a height along the centerline of the pipe for ease of operation and maintenance.

   Adhere to the "Water Flowing" Principle:Valves should be adjusted in the opposite direction of the water flow.Avoid installation at bends, reducers, tees, etc., to ensure the valve operates normally.

 3. Choose the Proper Installation Method:Generally, it should be horizontally installed on the pipeline, with the inclination angle not exceeding 5 degrees.If vertical installation is required, a support bracket should be set below the valve to maintain stability.

   Ensure Installation EnvironmentThe installation should be in a well-ventilated, dry, non-corrosive gas-free environment, conducive to operation and maintenance.The ground elevation should be appropriately set for ease of maintenance and repair.

5. Power Supply:If the pump control valve requires power supply, check the power lines for proper functionality before installation.

   Ensure Proper Installation:Ensure secure and reliable installation by employing appropriate fixed methods, such as flange connections, threaded connections, or welding joints, etc.

Maintenance Tips for Multi-Function Pump Control Valves

 Routine InspectionsRegularly inspect the equipment for loose connections and any damage. Check for blockages and leaks in the pump body and pipes.

  2. Cleaning and Maintenance:Regularly clean the equipment's exterior shell, fans, and heat dissipation holes to ensure optimal cooling performance. Maintain the cleanliness of the control valves to prevent dust and debris from entering the interior of the equipment.

  3. Replacement of Wearable PartsRegularly replace wearing parts, such as seals and filters, to ensure the smooth operation of equipment.
