EDRV dynamic balance electric control valve, dynamic balance electric two-way valve

EDRVDynamic balance electric control valveIt is a new generation product that differs from traditional electric control valves and integrates dynamic balancing and electric control.

EDRVDynamic balance electric adjustmentvalveworking principle:

EDRVDynamic balance electric control valveIn variable flow systems with large fluctuations in system load, when the system pressure changes, the pressure difference between the two ends of the dynamic balance electric control valve is dynamically balanced（P1-P3）It also changes accordingly:
⑴、When there is import pressureP1When rising, （P1-P2）Increase, at this point the electric valve core moves upward, causingP1、P2Reduced clearance, valve core pressureP2Reduce; When there is import pressureP1When decreasing, （P1-P2）Reduce, at this point the electric valve spool moves downward, causingP1、P2The opening degree increases, and the valve core pressure increasesP2rise. Therefore, no matter how the pressure of the system changes, through the regulating effect of the electric valve core,P2、P3The pressure difference between them remains constant. Therefore, this type of dynamic valve has strong anti-interference ability and dynamic balancing function;
⑵、When the linear electric actuator receives a control signal to extend the valve shaftA—BUp and down movement (or angular stroke electric actuator receiving control signal to extend valve shaft)RWhen rotating,P2、P3The opening between them also changes accordingly. Due to ignoring the system pressure difference（P1-P3）How to change,P2、P3The pressure difference between（P2-P3）Always unchanged, therefore corresponding to any opening position, the water flow rate conveyed is constant, and electricBalance valveThe actual flow characteristic curve and its ideal flow characteristic curve are *, without deviation. Therefore, this electric regulating valve has better regulating characteristics than traditional electric regulating valves.

EDRVDynamic balance electric control valveAdvantage

EDRV dynamic balance electric control valve, dynamic balance electric two-way valveHas excellent electric adjustment function：The electric adjustment function refers to the ability of a valve to automatically adjust its opening based on changes in the temperature control signal of the target area, thereby changing the water flow rate and ultimately ensuring that the actual temperature of the target area matches the set temperature.The flow characteristic curve of the electric regulating valve is used to evaluate the performance of the electric regulating function.

In air conditioning systems, the ideal flow characteristic curve of commonly used electric control valves is linear or proportional. However, for general electric control valves, in actual use, due to the small valve weight, the actual flow characteristic curve deviates from the ideal flow characteristic curve. As shown in the picture3The ideal flow characteristic curve of a certain electric regulating valve is a straight line (curve1）However, the actual flow characteristic curve after installation on the system pipeline is close to the fast opening type (curve2）The adjustment characteristics have deteriorated.Due to the valve body structure of *, the valve weight of the dynamic balance electric regulating valve is basically1Therefore, its actual flow characteristic curve and ideal flow characteristic curve * (as shown in the figure)4）There is no deviation, therefore it has excellent electric adjustment function.
