Basic introduction to Marine adjustable flow orifice plates:
Adjustable flow orifice can be used to replace the existing fixed
orifice plate. Its advantages are its tunability. It is mainly used
in cooling water system, which can be used with the closing valve
of cbm15-81 flange or cbm54-81. We recommend that the globe valves
should be installed on the front and rear lines of the orifice
plate.
The working principle of adjustable orifice plate of the ship:
Marine limited orifice plates can be used as flow measuring
elements to measure flow and can also be used as throttle
components to limit flow and reduce pressure. When the orifice
plate has a certain pressure difference, the fluid flows through
the orifice, and for a certain aperture, the flow through the
orifice increases with the pressure difference. But when the
pressure difference exceeds a certain value (referred to as the
critical pressure difference), the fluid through the orifice of
shrinkage cavity in the velocity to the speed of sound, at this
time, no matter how to increase pressure difference, as long as the
pressure upstream of the orifice plate keep a certain, flowing
through the orifice flow will be maintained at a certain value and
no longer increases. The limiting orifice plate is based on this
principle to limit fluid flow and reduce pressure.
