The pressure regulating valve KC50P-97 used in the sealing oil system of steam turbine generators is a valve used to control the oil hydrogen differential pressure. It is usually used to maintain the oil hydrogen differential pressure within the set range, ensuring the normal operation of the sealing oil system.

The working principle of the differential pressure regulating valve KC50P-97 is based on differential pressure control. When the pressure difference between oil and gas in the system exceeds the set threshold, the differential pressure valve will open or close to regulate flow and maintain the differential pressure within the set range.

The use of differential pressure valve KC50P-97 requires attention to the following aspects:

• 1. Installation position: When installing the regulating valve, a suitable installation position should be selected according to the system requirements and design criteria. Ensure that the differential pressure valve can receive differential pressure signals from the system normally and accurately control flow.
• 2. Differential pressure range: Understand the differential pressure range requirements of the system and select an appropriate differential pressure valve. Ensure that the rated differential pressure range of the differential pressure valve matches the system requirements to ensure its normal operation.
• 3. Valve adjustment: Regularly check and adjust the valve opening of the differential pressure valve based on the actual operation of the system. Ensure that the differential pressure valve can accurately control flow to meet the requirements of the system.
• 4. Leakage detection: Regularly check the differential pressure valve for leaks. If leakage is found, it should be repaired or replaced in a timely manner to prevent system performance degradation or damage to other equipment.
• 5. System pressure: Understand the working pressure range of the system and ensure that the rated pressure of the differential pressure valve can meet the requirements of the system. Avoid exceeding the rated pressure of the differential pressure valve to prevent valve damage or malfunction.
