The whole jacketed vortex flowing meter is suitable for petrochemical engineering enterprises which are prone to condensation and crystallization, can avoid maintenance, can reduce errors, can reduce trade dispute, and is safe in use.
Description
Technical field
The present invention relates to vortex-shedding meter field.
Background technology
There is many fluids for easily undergoing phase transition in use, the such as gaseous state in sour gas in the field such as chemical industry and petrochemical industry
The fluids such as sulfur, the carbamide in urea liquid, caprolactam, it is in fluid delivery process, as temperature constantly declines, last middle
The composition that easily undergoes phase transition occurs condensing or crystallizes, and is changed into liquid from gaseous state, or is changed into solid-state from liquid, in addition directly from
Gaseous state is changed into solid-state, condenses in effusion meter and connects liquid surface, and destruction vortex-shedding meter portion in contact with the electrolyte topology profile causes flux of vortex street
Meter cannot produce normal Karman vortex street, cause measurement failure.
Tradition is jacket structured：Only outer layer chuck, only heating stream tube outer surface.Due to stainless steel conduct heat compared with
Difference, passes to the shortage of heat of vortex shedder by chuck, and along with vortex shedder is in flow velocity highest zone, fluid is to which
Strong thermolysis is produced, brings runner pipe internal surface temperature higher, generation temperature is relatively low, may be produced under extreme case high
Up to 300 degree of the temperature difference.Even if inner-walls of duct is not adhered to, vortex shedder surface cannot still avoid the occurrence of condensation or crystallize,
Again result in and cannot produce Karman vortex street, ultimately result in measurement failure.
The content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided one kind is in addition to pipe sandwich, also straight to generating body inside
Connect into steam, and flow distribution valve is installed in outer end, the aperture of flow divider valve, distribution are adjusted according to on-site actual situations
Flow through the flow proportional of the heating medium of chuck and generating body so that inwall and generating body temperature equalization, all parts connect liquid temperature
Degree all far exceeds medium adiabatic condensation temperature or crystallization temperature, prevents the full jacket type vortex-shedding meter for condensing/crystallizing.
To realize the object of the invention, there is provided technical scheme below：A kind of full jacket type vortex-shedding meter, including fluid hose
The sensor housing on the sensor on rear side of vortex shedder, vortex shedder, fluid line side wall in road, fluid line,
It is connected the gauge outfit of polished rod and polished rod connection with sensor housing, it is characterised in that outside fluid line, be arranged with chuck, chuck and stream
Gap between body pipeline outer wall constitutes heating passage, and dividing plate is provided between chuck and fluid line, will heating channel partition into upper
Lower two chambers, vortex shedder center offer through hole, and through hole connects upper and lower two chambers, and the side of upper chamber is provided with steaming
Vapour air inlet pipe, opposite side arrange vapor communication pipe connection lower chambers the same side, and lower chambers are provided with steaming with steam inlet duct homonymy
Vapour escape pipe, is provided with flow divider valve on vapor communication pipe.
Preferably, fin is provided with polished rod.
Preferably, dividing plate is arranged at fluid line center, by upper and lower two chambers decile.
Beneficial effect of the present invention：Easily there is the enterprise of lime set, crystallization suitable for petrochemical industry etc., it is to avoid safeguard, reduce missing
Difference, reduces trade dispute, using safety.Compared with common jacket, the unification of liquid spot temperature is connect, prevents lime set completely.

Specific embodiment
Embodiment 1：A kind of full jacket type vortex-shedding meter, including the vortex shedder in fluid line 1, fluid line 1
2nd, on rear side of vortex shedder 2 sensor housing 4 on sensor 3,1 side wall of fluid line, and the connection polished rod of sensor housing 4
5th, and the connection of polished rod 5 gauge outfit 6, be arranged with chuck 7 outside fluid line 1, the gap between 1 outer wall of chuck 7 and fluid line is constituted
Heating passage, is provided with dividing plate 8 between chuck 7 and fluid line 1, dividing plate 8 is arranged at 1 center of fluid line, will heating passage point
It is divided into the chamber of upper and lower two deciles（9、10）, 2 center of vortex shedder offers through hole 2.1, and through hole 2.1 connects upper and lower two
Chamber（9、10）, the side of upper chamber 9 is provided with steam inlet duct 11,12 connection lower chambers 10 of opposite side setting vapor communication pipe
The same side, lower chambers 10 are provided with steam outleting pipe 13 with 11 homonymy of steam inlet duct, are provided with flow on vapor communication pipe 12
Distributing valve 15.Fin 14 is provided with polished rod 5.
In order to user installation is convenient, the present invention can be according to on-site steam source direction, and unrestricted choice steam connects at the scene
Point, it is to avoid the caused complicated adapter because steam source direction and entry position are differed.
