Description

The online induction type vortex shedding flow meter of more remodeling
Technical field
The utility model relates to a kind of measurement mechanism of pipeline inner fluid flow, specifically a kind of online induction type vortex shedding flow meter of more remodeling.Can be used in the measuring channel all kinds of flow medias as the flow of steam, gas, liquid.
Background technology
We know, the seventies in last century first vortex shedding flow meter birth, cause a sensation world's flow industry, U.S. expert prophesy can replace the restriction device of having widely applied last a century in the near future.In decades, the various countries scientist, flow industry scientific and technical personnel, users have experienced unremitting effort in scientific research, production, application, the vortex shedding flow meter that principle such as thermistor, piezoelectric crystal, differential capacitor, ultrasound wave and device are made has appearred in succession, because its core component detects the vortex street sensor of flow signal, when faults such as its appearance damage and leakage, need arrhea and to change maintenance.But above-mentioned flowmeter can not be implemented in line does not mostly arrhea replacing maintenance sensor.
Arrhea maintenance and mean that production line will stop production, stopping production is that in the modern production avoids greatly, stops production one hour with regard to possible loss units up to a million as petrochemical plant, even more, and heating network not only influences production, also will influence the common people's normal life.Therefore users very expect function admirable, install and online removable flowmeter easily.At present the problem that exists of online removable vortex shedding flow meter has: the defective that (), structural design exist such as the patent No. be 01205954.4 and the patent No. be that 101979964A all adopts connected structure, its common ground is that the vibrating arm that will the probe of sensing element be housed is plugged on another similar metal vibrating arm or elastic body and support chamber grafting, and another common ground all is to adopt strip piezoelectric crystal sensing element.Their shortcoming is to manufacture complexity, processing and assembling difficulty are big, be difficult to produce in batches, particularly its contact point easily produces vibration noise, influences the transmission of swirling action power, and signal quality can not show a candle to the monomer sonde configuration, the anti-vibration performance is very poor, therefore signal to noise ratio (S/N ratio) is relatively poor, can't operate as normal when serious, more be difficult to measure low discharge.The quality of signal to noise ratio (S/N ratio) is the important indicator that directly influences the flowmeter performance quality.(2), the defective that exists of sensing element piezoelectric crystal electricity principle and structure above-mentioned be mostly be encapsulated in piezoelectric crystal in the probing shell or fastening sealing to be integral as the patent No. be 01261173.5,01205954.4, in case damage can't onlinely change.The patent No. is 01261173.5, it is the bottom surface that is close to the probe metal shell that its disc piezoelectric ceramics adopts an end electrode plate, namely connect together with the earth and draw signal wire by casing or briquetting, the other end battery lead plate is with the insulation of probe metal shell and draw another signal wire, the sort signal lead-in wire is subject to the influence that vagabond current disturbs owing to not unsettled with the earth.Above-mentioned piezoelectric crystal electricity principle is parallel way, signal a little less than, poor signal to noise, when mechanical vibration, can superpositing vibration on the flow signal signal, when vibration signal during greater than flow meter signal flow signal strange the change taken place, cause leaky wave or increase ripple, this just causes measuring result error very big, can't operate as normal when serious, and the blank pipe when no fluid is mobile is all the more so.Signal to noise ratio (S/N ratio) is to weigh the performance index that flowmeter is important.Because poor signal to noise, the flow too weak detection of hour signal do not come out, and can survey minimum flow, claim the lower limit flow yet, are the another important performance indexes of weighing a flowmeter.
