The main function of a check valve is to protect mechanical equipment in a piping system by preventing the reversal of flow by the fluid. Check Valves (also called Non-Return Valves) are unidirectional. Flow is only allowed to pass in one direction, and this property has many uses in flow systems. An example would be to place a non-return valve on the discharge side of a pump/compressor, where backflow could damage the internals of the equipment and cause an unnecessary shutdown of the system.
The table below shows the application of different check valve components available in the FluidFlow database:
The table below shows the required data input and the output for the check valve components. Note that the results table varies depending upon the fluid phase state and the visible properties selected by the user.
Valves A valve is a device that regulates, directs, and controls the flow of fluids by opening, closing, or partially obstructing various passageways. Manually (or remotely) operated valves are typically used in on/off duties. Sometimes a valve can ...
Relief Devices FluidFlow allows you to model two types of relief devices, relief valves, and bursting discs. Users have the option of defining the size of the valve or disc or alternatively, allowing the software to automatically size the components ...
Boundaries Hydraulic models operate with single or multiple origins and destination points. These "points" are called boundaries within the concept of FluidFlow. Boundaries are therefore the points where the model starts and terminates. Correct ...
Boosters Booster is a general term for any fluid machine that adds energy to a fluid and is commonly called an energy-absorbing device. Boosters are mechanical devices that transport fluid from source to destination by increasing fluid pressure. ...
Size Change Size change components bring about a sudden change in velocity at the component. This can be caused by a change in the size of inlet and outlet pipes or by a sudden constriction. In FluidFlow, the thin sharp-edged orifice, thick orifice, ...
