3. Operating Principle
1)The mechanism of opening and closing the main valve within the pressure differential principle check valve is ingeniously designed..
When supplying water downstream, the outlet gate valve opens, allowing water from the middle chamber to flow downstream while the pressure P2 drops. In this state, the left-side pressure P1 of the elbow piston surpasses the right-side spring pressure (PZh), prompting the piston to shift rightward as depicted in the diagram, simultaneously opening the main valve with a quick-opening valve disc. Consequently, the inlet valve must overcome the spring's additional resistance. The medium flows from the valve disc's outer edges to the middle chamber, facilitating downstream water supply. As flow increases, P2 continues to drop, causing the piston to move rightward until the main valve is fully open, ensuring optimal flow and function.
When downstream water supply halts, the outlet valve closes, causing pressure in the middle chamber to rise, nudging the piston leftward as illustrated in circle 3, until it achieves a secure closure.
2) The opening and closing dynamics of the pressure differential principle check valve's drain valve are meticulously governed.
In adherence to national standards, the drain valve should automatically commence drainage when P1-P2 measures 14 KPa. As the pressure differential P1-P2 steadily declines, the drain valve maintains its drainage function until it is fully opened, evacuating the middle chamber and establishing an air gap between the inlet chamber and the middle chamber.
Following the drainage activity, P2 decreases. When P1-P2 descends below 14 KPa, the drain valve automatically shuts, effectively thwarting any potential medium backflow, thereby maintaining system integrity.
Should P1 further decline under these conditions, the drain valve will persist in opening until it is completely open, effectively draining the middle chamber and converting it into an empty space. This action ensures the creation of an air gap between the inlet chamber and the middle chamber, preventing any backflow from the middle chamber to the inlet chamber under all operating conditions.
