Unscrew the adjusting screw ring, people like a thin iron rod extending from the exposed screw tool, you can toggle adjustment ring on the teeth, so that the adjustment ring turning left. When the adjustment ring to the left for counterclockwise rotation, the position increased discharge pressure and reseating pressure will be reduced. Conversely, when the adjustment ring to the right for clockwise rotation, its lower position, the discharge pressure and reseating pressure will be higher. Each adjustment, adjustment: ring rotation rate should not be too large (typically several teeth can turn). After each adjustment screws should be fixed on the Weifang A38Y-16C safety valve, it ends in the adjustment ring groove between two teeth Shandong valve, both to prevent rotation of the adjustment ring Weifang double spring safety valve, not on the adjusting ring radial pressure. Safety valve for safety reasons, before toggle adjustment ring, valve inlet pressure should be appropriate to reduce the (generally less than 90% of the opening pressure), in order to prevent a sudden turn when adjusting the valve, causing the accident.
