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, such as gaseous state in sour gas in the field such as chemical industry and petrochemical industry
The fluids such as sulphur, the urea in urea liquid, caprolactam, it is last middle because temperature constantly declines in fluid delivery process
The composition that easily undergoes phase transition occurs condensing or crystallizes, and liquid is changed into from gaseous state, or is changed into solid-state from liquid, in addition directly from
Gaseous state is changed into solid-state, condenses in flowmeter 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 to fail.
Tradition is jacket structured：Only outer layer chuck, only heating stream tube outer surface.Due to stainless steel heat transfer compared with
Difference, the shortage of heat of vortex shedder is transmitted to by chuck, and along with vortex shedder is in flow velocity highest zone, fluid is to it
Strong thermolysis is produced, brings runner pipe internal surface temperature higher, generation temperature is relatively low, there may be height under extreme case
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 resulting in cannot produce Karman vortex street, ultimately result in measurement failure.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided one kind is also straight to generating body inside in addition to pipe sandwich
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 of the generation of condensation/crystallization.
To realize the object of the invention, there is provided following technical scheme：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,
The gauge outfit of polished rod and polished rod connection is connected with sensor housing, it is characterised in that chuck, chuck and stream are arranged with outside fluid line
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 offers 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 sets vapor communication pipe connection lower chambers the same side, and lower chambers are provided with steaming with steam inlet duct homonymy
Vapour escaping pipe, flow divider valve is provided with vapor communication pipe.
Preferably, being provided with fin on 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 occur the enterprise of lime set, crystallization suitable for petrochemical industry etc., it is to avoid safeguard, reduce and miss
Difference, reduces trade dispute, uses safety.Compared with common jacket, the unification of liquid spot temperature is connect, lime set is prevented 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 the sensor 3 of the rear side of vortex shedder 2, the side wall of fluid line 1 sensor housing 4 and the connection polished rod of sensor housing 4
5 and the gauge outfit 6 of the connection of polished rod 5, chuck 7 is arranged with outside fluid line 1, the gap between chuck 7 and the outer wall of fluid line 1 is constituted
Heating passage, is provided with dividing plate 8 between chuck 7 and fluid line 1, dividing plate 8 is arranged at the center of fluid line 1, by heating passage point
It is divided into the chamber of upper and lower two deciles（9、10）, the center of vortex shedder 2 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, the connection lower chambers 10 of opposite side setting vapor communication pipe 12
The same side, lower chambers 10 are provided with steam outleting pipe 13 with the homonymy of steam inlet duct 11, and flow is provided with 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 complicated adapter caused by differing because of steam source direction and entry position.
