Description
Technical field
The present invention relates to vortex-shedding meter and make field.
Background technology
Generally exist in gaseous fluid containing a large amount of solid-states in various fields such as metallurgy, cement, non-ferrous metal, Coal Chemical Industries or
The phenomenon of viscous liquid impurity, in effusion meter runs, what these impurity dirts were constantly attached to effusion meter connects liquid surface, gradually
Change effusion meter connects liquid profile so that measurement error constantly increases, and ultimately results in and cannot detect.To this current counter-measure
It it is the cleaning being carried out effusion meter by manual demolition.Conventional flowmeter structure can only enter after stopping production and completing purging
Row removes cleaning, recovers the work of effusion meter, even generally believing that the most perfect scheme effusion meter can use at present
Under state, continuous stream carries out dismounting this new structure, it is also difficult to avoids producing and reveals, particularly with corrosion and inflammable and explosive etc.
This class of hazardous fluids, need to use with caution, and therefore unless experience overhaul, the effusion meter of the dirty gas of the most substantial amounts of measurement is therefore
It is chronically at the state of shutting down.
Common blow device arranges unreasonable on the market, purges weak effect, and the electromagnetic valve for purging is susceptible to leakage.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of system structure is simple, is greatly improved purging efficiency, system
Stable, effectively prevent the automatic blowing control system of the vortex-shedding meter of the electromagnetic valve leakage of purging.
For realizing the object of the invention, it is provided that techniques below scheme: the automatic blowing control system of vortex-shedding meter, it is special
Levying and be that this control system is installed on the plug-in type vortex street probe of band purging, the plug-in type vortex street probe of described band purging includes
Fluid line, front and back vortex shedder, sensor install housing, polished rod, the gauge outfit of polished rod end, and sensor one end is installed on biography
On sensor housing, sensor end of probe is inserted in fluid line, and sensor connects gauge outfit by holding wire, is inserted with and blows in polished rod
Sweeping pipe, front vortex shedder center offers purging centre bore, and purging center bore inner wall offers several to surrounding sidewall
The purging aperture tilted, scavenging conduit bottom connects purging centre bore, and described control system includes embedded Micro Energy Lose CPU, purging
Medium transfer pipeline, described blowing medium transfer pipeline end connects scavenging conduit, and blowing medium transfer pipeline is from top to end
On be sequentially arranged hand stop valve, high pressure check valve, electronic quick ball valve, embedded Micro Energy Lose cpu signal connect electronic soon
Speed ball valve.
As preferably, embedded Micro Energy Lose CPU accesses purge cycles and controls parameter module, purging duration control parameter module
And Purge methods controls parameter module.
Use embedded Micro Energy Lose CPU, parameter is set: purge cycles, how long purge once；Purge often, every time
The purging persistent period；Purge methods, is divided into pulsation purging and purges continuously.When needs purge, CPU gives one to control output,
Electronic quick ball valve is driven to open.Blowing medium (steam, pressure sky, propylene gas etc. are allowed for the fluid purged), through manually
Stop valve enters high pressure check valve, is connected to purging probe through electrical ball valve.
Hand stop valve: for the system maintenance stage, when system maintenance, manually can isolate blowing medium by stop valve
And detected fluid medium.
High pressure check valve effect: preventing blowing medium pressure less than fluid pressure, last detected fluid passes through electrical ball valve
The anti-blowing medium that pours into, accidents caused.Under normal circumstances, blowing medium pressure have to be larger than fluid maximum pressure 20%, to ensure
Blowing medium one-way flow only, once purging pressure occur less than detected fluid pressure, due to the setting of high pressure check valve,
Block that detected fluid is counter pours into blowing medium, it is provided that extra protection.
The method have the benefit that present system simple in construction, be greatly improved purging efficiency, system stability, effectively prevent
The electromagnetic valve leakage of purging, suitable for industrial is applied.
Accompanying drawing explanation
Fig. 1 is present system schematic diagram.
Fig. 2 is the plug-in type vortex street probe schematic diagram of band purging.
Detailed description of the invention
Embodiment 1: the automatic blowing control system of vortex-shedding meter, this control system is installed on the plug-in type whirlpool of band purging
On the probe of street, the plug-in type vortex street probe of described band purging includes fluid line 1, front and back vortex shedder (2,3), sensor peace
Dress housing 4, polished rod 5, the gauge outfit 6 of polished rod 5 end, sensor 7 one end is installed on sensor housing 4, and sensor 7 end of probe is inserted
Entering in fluid line 1, sensor 7 connects gauge outfit 6 by holding wire, is inserted with scavenging conduit 8, in front vortex shedder 2 in polished rod 5
The heart offers purging centre bore 2.1, and purging centre bore 2.1 inwall offers several purging apertures tilted to surrounding sidewall
2.2, scavenging conduit 8 bottom connects purging centre bore 2.1, and described control system includes that embedded Micro Energy Lose CPU 9, blowing medium are defeated
Sending pipeline 10, described blowing medium transfer pipeline 10 end connects scavenging conduit 8, and blowing medium transfer pipeline 10 is from top to end
On be sequentially arranged hand stop valve 11, high pressure check valve 12, electronic quick ball valve 13, embedded Micro Energy Lose CPU 9 signal is even
Connect electronic quick ball valve 13.Embedded Micro Energy Lose CPU 9 accesses purge cycles and controls parameter module 14, purging duration control parameter
Module 15 and Purge methods control parameter module 16.
Embodiment 2: the automatic blowing control system control method of vortex-shedding meter, when arriving the timing of purge cycles,
First by current real-time flow data, be stored in memorizer, and using this flow as flowmeter output signal, later on electronic soon
Speed ball valve, the Purge methods according to setting of opening of electronic quick ball valve has 2 kinds: 1, often keep within often at regulation purging
Open；2, carrying out opening and closing of pulsing within the purging duration of regulation, opening and closing ratio (and pulse duty factor) time scale can set separately
Put, to adapt to different purging requirements.After purging duration terminates, close electronic quick ball valve, recover real-time traffic signal
Detection and pick-up output.Owing to blowing medium can direct interference flow signal.Blowing medium interference flow signal when, make
Continue to put out with the flow signal before purging, owing to effusion meter itself is not particularly suited for the detection of pulsating flow, therefore can recognize
For, flow itself is gradual, according to on-the-spot operating mode, sets and reasonably purges duration, still can realize whole factory certainly
Flow monitoring precision needed for dynamicization control.
