Product Overview
HLG SERIES self-control whole set throttling devices are widely applied in industries sectors
Such as metallurgy, power, chemical, pharmacy, food, military, scientific research, etc. They are used
To measure, control and adjust flow of the fluids (liquid, gas and vapors). The throttling devices are
With the advantages of simple structure, easy maintenance, reliable performance and high measuring
Accuracy.
Basic Principle
When the fluid filled in the pipe is flowing through the throttling device in the pipe, the flow will
Shrink partly at the throttling device, hence the flow velocity increases while the static pressure
Decreases to form the differential pressure at the back and forth of the throttling device. The bigger
The flow rate, the larger the differential pressure, so we can measure the flow according to differential
Pressure. This measuring method is based on Fluxion Continuity Equation (Mass Conservation Law)
And Bernoulli's Principle (Energy Conservation Law). The differential pressure is related to flow, as
Well as other factors. For example, when the forms of throttling devices or physical properties (density,
Viscosity) of the fluids in the pipe are different, the differential pressure generates at the same flow rate
Is different.
Classification according to the structure
1)Standard Orifice Plate: Also called Square Edge Concentric Orifice Plate, is a kind of circular
Concentric sheet with sharp square edges. The edges of the bores at the upstream should be sharp
Square angles. Three tapping modes can be provided: Corner tapping, flange tapping and D-D/2
Tapping. In order to measure in either of the two directions, we can use symmetrical orifice plate. The
Two edges of the orifice accord the features of upstream edges of the right-angle edge orifice plate, and
The total thickness of the orifice plate doesn't excess the thickness of the bores of throttling orifice.
2)Standard Nozzle
Two kinds of structure provided: ISA1932 Nozzle and Long Radius Nozzle.
A. ISA1932 nozzle: The nozzle with upstream face composed of the plane perpendicular to the axis,
The contracted section determined by two arc lines which the outline is circumference, the cylindrical
Throat and the groove. Only corner tapping for ISA 1932 Nozzle.
B. Long Radius Nozzle: The nozzle with upstream face composed of the plane perpendicular to the
Axis, the contracted section which the outline is 1/4 ellipse, the cylindrical throat and the groove or bevel.
