3. Operating Principle
1)The dynamic opening and closing mechanism of the main valve in this pressure differential principle check valve.
During operation, when water is needed downstream, the outlet gate valve opens. The water then flows effortlessly from the middle chamber to the downstream, lowering the pressure P2. Consequently, the left-side pressure P1 of the elbow piston surpasses the right-side spring pressure (PZh), prompting a smooth rightward movement of the piston and simultaneously opening the main valve with its quick-opening valve disc. The inlet valve effectively counters the spring's resistance, allowing medium flow from the outer sides of the valve disc into the middle chamber, supplying water downstream. As the flow rate intensifies, P2 decreases further, driving the piston to the right until the main valve reaches its full open position.
In contrast, when downstream water isn't required, the outlet water supply valve closes. This action raises the pressure in the middle chamber, moving the piston to the left, as depicted in circle 3, until it is completely closed.
2) The precise operation of the pressure differential principle check valve's drain valve.
Aligned with national standards: "When P1-P2 reaches 14 KPa, the drain valve intuitively opens for drainage. As the pressure difference P1-P2 continues to decline, the drain valve persistently opens, ensuring the middle chamber is devoid of water, thereby creating a necessary air gap between the inlet chamber and the middle chamber."
The resultant drainage causes P2 to decrease. When the pressure difference P1-P2 falls below 14 KPa, the drain valve automatically shuts, effectively safeguarding against medium backflow.
Should P1 continue its downward trend under these stipulated conditions, the drain valve remains open, facilitating the complete evacuation of the middle chamber, transforming it into a void space. This strategically produces an air gap between the inlet and middle chambers to prevent backflow under any operating scenario.
