Description
Technical field
The utility model is related to instrumentation field, especially a kind of novel V cone flow meters.
Background technology
V cone flow meters also known as V cone shaped flow meters, English name are V-cone flowmeter, and V cone flow meters are 20 generation
Record the eighties start research and development a kind of differential pressure flowmeter, it succeed in developing be differential pressure type flow measurement qualitative leap.V coning tower trays
Gauge operation principle is when the fluid full of pipeline, and when flowing through the flow-through orifice in pipeline, flow velocity will be in the throttling of flow-through orifice
Place forms local contraction, and to make flow velocity accelerate, static pressure reduces, and pressure drop is then just produced before and after standard orifice plate or is cried
The flow of pressure difference, media flow is bigger, and the pressure difference generated before and after flow-through orifice is also just bigger, thus can by measure pressure difference come
Measure the size of fluid flow.V cone flow meters be applied to the high region of temperature range in use, still can also normal use, work as the winter
Ji Yingyong is in the cold place in day in use, into fluid in V cone flow meters（Such as blast furnace gas and coke-stove gas）In it is remaining
Moisture bottom in V cone flow meters easily causes icing phenomenon, in this way, freezing seriously has occupied V cone flow meter circulation areas, leads
The read untrue of V cone flow meters is caused, is located at V cone flow meter enclosure interiors moreover, because freezing, if to remove, open V cones
The shell of flowmeter is extremely inconvenient, workload is very big, and shuts down removing and freeze and can be affected to the conveying of fluid；Work as part
Fluid media (medium), such as blast furnace gas and coke-stove gas but will come since blast furnace gas and coke-stove gas are inflammable and explosive to cleaning tape
It influences and there are security risks.
Invention content
For the use drawback for overcoming existing V-type cone flow meter to be brought because structure limits, the utility model is provided bores in V
Crust is increased outside the shell of flowmeter bodies, and air inlet pipe, exhaust pipe, this body running of V cone flow meters are provided on shell

The valve of only valve, the installation of third pipeline lower part uses shutoff valve.
The utility model advantageous effect is：The utility model measures application method and common V cone flow meters application method one
It causes, when import of the fluid through V cone flow meter ontologies enters enclosure interior, and after being flowed out from outlet, V cone flow meter ontologies are to fluid
It is measured.Meanwhile the valve of the heated gas feed of heat source air of hot-air occurrence of equipment output, into V-type coning tower tray amount
It between the shell and shell of counting ontology, and is discharged from the valve of heat gas outlet, hot-air is in V cone flow meters ontology and outside
It constantly recycles, the fluid in V cone flow meter body casing bodies is heated, while remaining on V cone flow meter ontologies in fluid in shell 2
Water in shell is not because temperature height will produce icing phenomenon.In actual use, when hot-air occurrence of equipment is boiler, V coning tower trays
Residual liquid can effectively be flowed out from second pipe lower part hydrophobic valve between the shell and shell of gauge ontology, and hot-air occurs
When equipment is electrical heating blower mechanism or production area fever working equipment, user can open second by certain interval of time
Residual liquid between the shell and shell of V-type cone flow meter ontology and dust are discharged pipeline lower part shutoff valve；User
Separated in time opens third pipeline lower part valve and can arrange the moisture of fluid remnants in the shell of V-type cone flow meter ontology
Go out.The utility model can effectively prevent the enclosure interior of V cone flow meter ontologies because freezing, and to V cone flow meters, this bulk measurement is brought
It influences, based on above-mentioned, so the application prospect that the utility model has had.
