Electromagnetic stainless steel regulating valve specific steps

According to the process, determine the diameter of the electromagnetic stainless steel regulating valve. The specific steps are:
1. First, the maximum flow Qmax and the minimum flow Qmin are calculated based on the equipment load of the production capacity.
2, according to the selected flow characteristics and system characteristics selected S value, and then according to the pressure distribution and pipeline losses, determine the minimum pressure difference △ Pmin and the maximum pressure difference △ Pmax.
3. Calculate the Kvs at the maximum flow rate according to the circulation capacity calculation formula.
4. According to the criteria of Kvs in the selected product type, select more than Kvs and approach the Kv value.
5, according to the selected Kv value and flow characteristics, verify the opening of the regulating valve, the required opening is between 10% and 90%. Regulator valve diameter selection step
6, calculate R, check the adjustable ratio.
7. After verification of each item, determine the valve diameter according to Kv value.
