For the structure of Weifang with recoil plate and seat adjustment ring double spring safety valve, is the use of seat adjustment ring to be adjusted. 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 valve, it ends in the adjustment ring groove between two teeth, both to prevent rotation of the adjustment ring, not on the adjusting ring radial pressure. To be safe valve manufacturers in the ring before the toggle adjustment should be made appropriate to reduce the inlet pressure relief valve (generally less than 90% of the opening pressure), in order to prevent a sudden turn when adjusting the valve, causing the accident. The adjustment ring is used to change the flow of the medium in the valve flap folding rear side reflection angle, thereby changing the size of the fluid forces, in order to adjust the pressure back seat. Increase the adjustment ring, the turning angle decreases, the fluid force decreases, so that the back seat pressure increased. Conversely Weifang A38Y-16C safety valve, when the adjustment ring on the lower back seat pressure is reduced. Of course, while the adjustment ring in the back seat pressure change also affects the discharge pressure, which increases the adjusting ring so that the discharge pressure has increased, reducing pressure on the adjusting ring so that emissions decreased, but the degree of impact is not back Pressure on as obvious.
