Electric adjustment of dynamic balance the advantages of pneumatic valve

in air conditioning and heating systems, cold ( Hot) Media distribution to each user by closed pipeline system. For a well-designed piping systems, each user in the end of the pneumatic control valve ( Electric pneumatic valve, pneumatic control valve, etc. ) The opening of the designs for the % should all can obtain water, and at the end of each user control of pneumatic valve opening change when can get the required flow and does not interfere with each other. The water system is a hydraulic balance system, otherwise it is unbalanced hydraulic system, hydraulic imbalance is also called the hydraulic imbalance.

hydraulic disorder generally divided into two kinds of static imbalance and dynamic disorder.

the so-called static disorder is also known as steady-state misadjustment. The system, each user under design condition, actual traffic does not accord with the design discharge. This kind of hydraulic imbalance is fundamental, if not solved, always there. For constant flow system, the disorder phenomenon available static balance action valve pneumatic valve or electric two ventilation to solve.

dynamic disorder is also known as stability disorder. The system, the change of chilled water when some users ( Closed or adjust) , will cause the resistance distribution of system changes, resulting in the flow of other users with the change. The hydraulic imbalance is random and dynamic change. The change of the local traffic to other users is small, the influence of the degree of the hydraulic imbalance is small, hydraulic stability is good. On the other hand, the degree of hydraulic misadjustment is big, hydraulic stability is poor. The disorder phenomenon of static balance action valve pneumatic valve or electric two ventilation is unable to solve, can only be solved with dynamic balance of electric pneumatic valve adjustment.
