3. Operating Principle
1)The dynamic operation of the main valve in the pressure differential principle check valve is a testament to engineering prowess..
As water flows downstream, the gate valve at the outlet springs open, allowing water from the middle chamber to cascade downstream. This causes a drop in pressure P2. Consequently, the left pressure P1 on the elbow piston overcomes the spring's resistance on the right (PZh), moving the piston rightward as illustrated, and engaging the main valve with its quick-opening valve disc. The inlet valve navigates the extra spring loss with finesse as the medium moves from the valve disc's sides to the middle chamber, supplying water downstream. As flow increases, P2 diminishes further, propelling the piston right until the main valve is entirely open.
When downstream water supply ceases, the outlet valve closes. This triggers a pressure rise in the middle chamber, causing the piston to shift leftward as depicted in circle 3, ensuring a secure closure.
2)The meticulous opening and closing of the check valve's drain valve adhere to stringent standards.
In alignment with national standards: When P1-P2 reaches 14 KPa, the drain valve instinctively opens, ensuring effective drainage. As the pressure difference dwindles, the drain valve remains active until it fully opens, clearing the middle chamber and establishing an air gap between the inlet and middle chambers.
Continued drainage from the valve reduces P2. Should P1-P2 fall below 14 KPa, the valve promptly seals, thwarting any potential backflow of the medium.
If under these conditions P1 keeps decreasing, the drain valve will persistently open until it fully evacuates water from the middle chamber, creating a void. This achieves an air gap between the inlet and middle chambers, preventing backflow under any operational circumstance.
