3. Operating Principle
1)Witness the seamless opening and closing of the main valve within this pressure differential principle check valve..
When supplying water downstream, this sophisticated system activates as the outlet gate valve opens, allowing water from the middle chamber to flow effortlessly downstream. With the decrease in pressure P2, the left-side pressure P1 of the elbow piston triumphs over the spring's resistance (PZh), driving the piston rightward, and simultaneously triggering the quick-opening valve disc of the main valve. As the flow intensifies, P2 continues to drop, facilitating the piston's rightward motion until the main valve attains its fully open state.
Conversely, when downstream water supply halts, the outlet water supply valve closes, causing middle chamber pressure to rise, shifting the piston leftward until a complete closure is achieved.
2) Observe the precision in the opening and closing mechanism of the pressure differential principle check valve's drain valve.
Aligned with the national standard: When P1-P2 reaches 14 KPa, the drain valve instinctively opens, initiating drainage. If this pressure difference drops further, the valve remains open, emptying the middle chamber and establishing a vital air gap between the inlet and middle chambers.
As the drain valve facilitates drainage, a decrease in P2 follows. However, when P1-P2 falls below 14 KPa, the valve closes automatically, ensuring an impeccable prevention of backflow.
Should P1 persistently decline under these conditions, the drain valve will remain open until it achieves full openness, vacating the middle chamber and ensuring an air gap formation. This reliably prevents any potential backflow from the middle chamber to the inlet chamber under all operational scenarios.
