Automatic Back-Pressure Valve With Pneumatic Pressure Stabilization

The patent replaces the traditional manual mechanical spring adjustment system with an automatic pneumatic control system. Compressed air pressure acts on a diaphragm to automatically regulate the back-pressure valve opening, eliminating the need for manual spring adjustment and providing precise, stable pressure control without the fluctuations inherent in manual mechanical systems.

The patent introduces a pneumatic control mechanism where compressed air pressure is applied to a diaphragm. This pneumatic system automatically adjusts the valve opening based on pressure differential, providing precise and stable pressure control. The pneumatic actuation replaces the manual mechanical adjustment, achieving both high precision and automatic operation.

The patent implements a feedback mechanism where the system continuously monitors the pressure differential across the diaphragm. When system pressure exceeds the setpoint, the diaphragm automatically adjusts the valve opening to release excess pressure. When pressure drops below the setpoint, the spring closes the valve. This continuous feedback loop maintains stable pressure without manual intervention, eliminating the fluctuations caused by manual adjustment delays.

The back-pressure valve is designed to automatically regulate pressure without manual operation. The compressed air pressure on the diaphragm and the spring force work together to self-adjust the valve opening based on real-time pressure conditions. The system serves itself by automatically detecting pressure deviations and correcting them, eliminating the need for manual monitoring and adjustment that causes pressure fluctuations.
