Hydraulic control valve of the correct selection and matters needing attention

by:Mech     2020-07-02

hydraulic control valve is a hydraulic control valves, it consists of a main valve and attached catheter, pilot valve, needle valve, ball valve and pressure gauge, etc.

use hydraulic control valve, the first thing to pay attention to the selection. Improper selection, will cause the resistance and water leakage phenomenon. When selecting hydraulic control valves, must according to the equipment of the steam consumption per hour times choose ratio 2 - Three times as the biggest condensation water, hydraulic control valve to select displacement. To ensure that the hydraulic control Industrial Valves to discharge the condensate as soon as possible, while driving rapidly raise the temperature of heating equipment. Hydraulic control valve to discharge energy is insufficient, will cause the condensate can not discharge in time, reduce the thermal efficiency of heating equipment.

when selecting hydraulic control valves, can't choose to nominal pressure hydraulic control Industrial Valves, because the nominal pressure hydraulic control valve body shell stress level can only be said, nominal pressure hydraulic control valve and the pressure difference is very big. So want to choose according to the working pressure difference of displacement of the hydraulic control valve. Working pressure difference is refers to the hydraulic control valve in front of the working pressure minus the hydraulic control Industrial Valves to export back pressure difference. Choose vapor barrier drainage hydraulic control valve requires accurate, high sensitivity, can improve the utilization rate of steam, steam leakage, has reliable performance, high back pressure ratio, long service life, convenient maintenance is preferred.
