The principle of work of vortex precession flowmeter:
When fluid is by after the vortex generator that is made up of spiral vane, fluid is forced to acutely rotate around shedder axle, forms vortex.When fluid enters diffuser, the effect that bumpy flow is refluxed, starts to make secondary rotating, forms the eddy current precession phenomenon of gyroscope type.This precession frequency is directly proportional to uninterrupted, is not subject to the impact of physical property of fluid and density.Detecting element records fluid secondary rotating precession frequency, is just aware of flow.And the good linearity can be obtained in wider flow range.Flowmeter formula is:
K＝f/q
In formula: K---flow instrument coefficient
F---vortex frequency
Q---volumetric flow rate
The instrument coefficient of flowmeter has nothing to do with the temperature of fluid, pressure, component and physical property (density, viscosity) in the reynolds number range of certain structural parameters and regulation.
Flange is the blue flange of call again.Flange is interconnective part between pipe and pipe, for the connection between pipe end; Also the flange that the equipment that is used in is imported and exported is had, for the connection between two equipment, as reductor flange.Flange joint or bump joint, refer to and be interconnected releasable connection as one group of combined sealing structure by flange, pad and bolt three.Pipe flange means the flange of pipe arrangement in plumbing installation, is used in import and export flange equipment meaning equipment.Perforation on flange, bolt makes two flanges be close to.Liner containment is used between flange.Flange divides be threaded (screwed connection) flange, welding flange and clip flange.Flange is all use in pairs, and low pressure pipeline can use an acting flange, and four kilograms with the use welding flange of upward pressure.Add sealing gasket between two panels ring flange, then use bolted.The flange thickness of different pressures is different, and the bolt that they use is also different.Water pump and valve, when being connected with pipeline, the local of these equipment facilities, also makes corresponding flange shape, also referred to as Flange joint.Every union piece using bolt connection simultaneously to close at two planar perimeter, be generally all called " flange ", as the connection of ventilating duct, this class part can be called " flange type part ".But this connection is the local of an equipment, as the connection of flange and water pump, just bad water pump " flange type part ".More small-sized as valve etc., can cry " flange type part ".
