3. Operating Principle
1)The opening and closing mechanism of the main valve in this pressure differential principle check valve.
When the valve supplies water downstream, the outlet gate valve opens, allowing water from the middle chamber to flow through the outlet. This decreases the pressure P2. Consequently, the left-side pressure P1 of the elbow piston surpasses the spring pressure on the right (PZh), prompting the piston to move rightward, thereby opening the main valve with its quick-opening valve disc. The inlet valve then overcomes the spring's additional resistance, enabling the medium to flow from the outer valve disc to the middle chamber, supplying downstream water. As flow increases, P2 continues to decrease, driving the piston further right until the main valve is fully open.
When downstream water supply is not needed, closing the outlet water supply valve causes middle chamber pressure to rise, moving the piston leftward until fully closed.
2) The operation of the pressure differential principle check valve's drain valve.
In line with national standards, when P1-P2 reaches 14 KPa, the drain valve automatically opens. As the pressure differential further drops, the valve continues draining until fully open, emptying the middle chamber and creating an air gap between the inlet and middle chambers.
Post drainage, as P2 decreases and P1-P2 falls below 14 KPa, the drain valve automatically closes, effectively blocking any backflow of medium.
If P1 continues to fall under these conditions, the drain valve remains open until it achieves full drainage, transforming the middle chamber into air-filled space, thus preventing any backflow under all circumstances.
