Diverter Valve Operation: Understanding How It Works
What are the key aspects of diverter valve operation?
Diverter Valve Operation Explained
The diverter valve operation involves several key aspects:
- Adjusting the amount of liquid or gas entering through different inlets
- Equalizing inlet pressure
- Controlling inlet flows by moving the plug position
- Maintaining a constant fluid level in a vessel
- Combining two flow streams into one stream
Moving Valve Stem for Varied Flow Proportion
A) Moving the stem of the valve changes how much liquid or gas is entering through different inlets. Regardless of the valve plug's position, there is a continuous flow from the outlet.
Equalizing Inlet Pressure for Balanced Operation
B) The inlet pressure acts equally on both valve plugs, which reduces the force required to move the valve stem. If there is a difference in pressure between discharge lines, an imbalance will occur.
Controlling Inlet Flows with Plug Position
C) The plug of the valve controls the flow from different inlets. When the plug is fully down, the bottom inlet is shut off, and when it is fully raised, the side inlet flow is shut off. The plug can be adjusted to an intermediate position to proportion the two inlet flows based on operational needs.
Maintaining Fluid Level in Vessel
D) The valve can help maintain a constant level of fluid in a vessel. If the inlet flow is too high when the maximum level is reached, the excess input can be diverted to another vessel.
Combining Flow Streams
E) The valve has the capability to bring two different flow streams together into one stream, allowing for efficient operation and utilization of resources.
Understanding the operation of a diverter valve is essential for ensuring efficient and effective flow control in various industrial processes.
