Description
Technical field
This utility model is related to vortex-shedding meter and makes field.
Background technology
In the various fields generally existing gaseous fluid such as metallurgy, cement, non-ferrous metal, Coal Chemical Industry contain a large amount of solid-states or
The phenomenon of viscous liquid impurity, in effusion meter operation, 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 is the cleaning that effusion meter is carried out by manual demolition.Conventional flowmeter structure stopping production and can only can enter after completing purging
Row removes cleaning, recovers the work of effusion meter, even generally believing that scheme-effusion meter the most perfect can used at present
Under state, not stopping carries out dismounting this new structure, it is also difficult to avoid producing leakage, particularly with corrosion and inflammable and explosive etc.
Hazardous fluids this classes, need to be used with caution, therefore unless experience overhaul, and the effusion meter of the dirty gas of otherwise substantial amounts of measurement is therefore
It is chronically at the state of shutting down.
Common blow device arranges unreasonable on the market, and purging effect is poor, and the electromagnetic valve for purging is susceptible to leakage.
The content of the invention
This utility model is directed to the deficiencies in the prior art, there is provided a kind of system structure is simple, greatly improves purging efficiency,
System stability, effectively prevents the automatic blowing control system of the vortex-shedding meter of the electromagnetic valve leakage for purging.
To realize this utility model purpose, there is provided technical scheme below：The automatic blowing control system of vortex-shedding meter,
It is characterized in that the control system is installed on the plug-in type vortex street probe with purging, the plug-in type vortex street probe with purging
Including fluid line, vortex shedder, sensor install the gauge outfit of housing, polished rod, polished rod end in front and back, and sensor one end is installed
On sensor housing, in sensor end of probe insertion fluid line, sensor is plugged in polished rod by signal linear list head
There is scavenging conduit, front vortex shedder center offers purging centre bore, if offering to four the week side of boss walls on purging center bore inner wall
A dry inclined purging aperture, scavenging conduit bottom connection purging centre bore, the control system include embedded Micro Energy Lose CPU,
Blowing medium transfer pipeline, the blowing medium transfer pipeline end connect scavenging conduit, blowing medium transfer pipeline from top to
Hand stop valve, high pressure check valve, electronic quick ball valve, embedded Micro Energy Lose cpu signal connection electricity have been sequentially arranged on end
Move quick ball valve.
Preferably, embedded Micro Energy Lose CPU accesses purge cycles control parameter module, purging duration control parameter module
And Purge methods control parameter module.
Using embedded Micro Energy Lose CPU, arrange parameter：How long purge cycles, purge once；Purge often, every time
The purging persistent period；Purge methods, are divided into pulsation purging and continuous purging.When purging is needed, CPU gives a controlled output,
Electronic quick ball valve is driven to open.Blowing medium（Steam, pressure sky, propylene gas etc. are allowed for the fluid for purging）, through manual
Stop valve enters high pressure check valve, is connected to purging probe through electrical ball valve.
Hand stop valve：For the system maintenance stage, in system maintenance, manually can isolate blowing medium by stop valve
And detected fluid medium.
High pressure check valve is acted on：Prevent blowing medium pressure less than Fluid pressure, last detected fluid passes through electrical ball valve
It is counter to pour into blowing medium, it is accidents caused.Under normal circumstances, blowing medium pressure have to be larger than fluid maximum pressure 20%, to ensure
Blowing medium only one-way flow, when there is purging pressure less than detected fluid pressure, due to the setting of high pressure check valve,
Block that detected fluid is counter to pour into blowing medium, there is provided extra protection.
This utility model beneficial effect：This utility model system structure is simple, greatly improves purging efficiency, system stability,
The electromagnetic valve leakage for purging, suitable for industrial application are prevented effectively.
Description of the drawings
Fig. 1 is this utility model system schematic.
Fig. 2 is the plug-in type vortex street probe schematic diagram with purging.
Specific embodiment
Embodiment 1：The automatic blowing control system of vortex-shedding meter, the control system are installed on the plug-in type whirlpool with purging
On the probe of street, the plug-in type vortex street probe with purging includes fluid line 1, in front and back vortex shedder（2、3）, sensor peace
Dress housing 4, polished rod 5, the gauge outfit 6 of 5 end of polished rod, 7 one end of sensor are installed on sensor housing 4, and 7 end of probe of sensor is inserted
Enter in fluid line 1, sensor 7 is inserted with scavenging conduit 8 in polished rod 5, in front vortex shedder 2 by signal linear list head 6
The heart offers purging centre bore 2.1, offers several inclined purging apertures to four the week side of boss walls on purging 2.1 inwall of centre bore
2.2,8 bottom of scavenging conduit connection purging centre bore 2.1, the control system include that embedded Micro Energy Lose CPU 9, blowing medium is defeated
Pipeline 10,10 end of blowing medium transfer pipeline is sent to connect scavenging conduit 8, 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 9 signals of Micro Energy Lose CPU connect
Connect electronic quick ball valve 13.Embedded Micro Energy Lose CPU 9 accesses purge cycles control 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 the timing of purge cycles is reached,
First by current real-time flow data, memorizer is stored in, and using this flow as flowmeter output signal, it is later on electronic fast
Fast ball valve, the unlatching of electronic quick ball valve have 2 kinds according to the Purge methods of setting：1st, keep normal within often in regulation purging
Open；2nd, pulsation opening and closing is carried out within the purging duration of regulation, be opened and closed ratio（And pulse duty factor）Time scale separately can set
Put, to adapt to different purging requirements.After purging duration terminates, electronic quick ball valve is closed, recovers real-time traffic signal
Detection and pick-up output.As blowing medium can direct interference flow signal.When blowing medium disturbs flow signal, make
Continued to output with the flow signal before purging, as effusion meter is not particularly suited for the detection of pulsating flow in itself, therefore can be recognized
For flow is gradual in itself, and according to the operating mode at scene, the rational purging duration of setting can still realize whole factory certainly
Flow monitoring precision needed for dynamicization control.
