the regulator is a device used for daily production and life. This equipment is mainly used to control the water pressure, water flow through the reasonable range of the valve. It is very common in our daily life of the valve, the effect is very good. The working principle of voltage regulator valve when pipe water supply from the entrance to the end, water flows through a needle into the main valve control room, acting on pilot Industrial Valves outlet pressure through the catheter. When the outlet pressure is higher than the guide valve set point, pilot valve closed, emissions control room to stop. At this point, the main valve control intraluminal pressure rise and close the main valve, outlet pressure rise no longer. When the outlet pressure drop to the guide set pressure pilot valve to open, the control room to the downstream. As a result of the pilot valve displacement is greater than the needle valve inlet, so the main valve pressure drop in the control room, and inlet pressure lead to the main valve to open. Under steady state, the control room with the same drainage and drainage, opening unchanged, outlet pressure constant. Can be set by adjusting the guide valve spring outlet pressure.
