Abstract
A flow control device 1! for insertion into a conduit to control the flow rate of fluid flow therethrough. The device 1! includes two opposed dished baffle plates 2! and 3! defining a chamber 4! therebetween. Each baffle plate has a generally centrally located orifice 6! and 7! respectively. The device 1! is adapted for positioning substantially transverse to the longitudinal extent of the conduit by means of, for example, flanges 10 and 11! or a pre-connected threaded sleeve 15!, such that fluid flow along the conduit is diverted through the orifices 6! and 7!. Additional spaced baffle plates 5! may be added on the downstream side to fine tune the flow rate.
Claims7
A flow control device for controlling the flow rate of a fluid flowing through a conduit from an upstream side of said device to a downstream side of said device, said device comprising two opposed dished baffle plates defining a chamber therebetween, each said dished baffle plate having a generally centrally located hole therein, wherein on said downstream side said device further comprises at least one additional dished baffle plate having a generally centrally located hole, said additional dished baffle plate being positioned in a nested configuration with said baffle plate of said downstream side of said device, said baffle plate of said downstream side of said device and said additional baffle plate having a space between said holes of said baffle plate of said downstream side of said device and said additional baffle plate, respectively, whereby positioning said device substantially transverse to the longitudinal extent of said conduit and diverting said fluid through said holes controls the flow rate of said fluid.
