Product Description
The main function of the one-way check valve RCV2.5 in the EH oil control system is to prevent oil backflow and ensure that oil can only flow in one direction. Specifically, this type of valve allows fluid to flow unidirectionally under forward pressure, while automatically closing under reverse pressure to prevent fluid backflow.
In the EH oil system of the steam turbine, the main functions of the check valve RCV2.5 include:
1. Prevent backflow: Ensure that EH oil does not backflow in the event of system failure or shutdown, avoiding damage to the system.
2. Quick response: The one-way check valve needs to respond quickly to meet the requirements of the emergency shutdown system for quickly cutting off oil flow.
3. High pressure resistance: The working environment pressure of the steam turbine is high, and the one-way check valve must be able to withstand the system working pressure.
