Description

A kind of flow controller

Technical field

This utility model relates to fluid flow control field, is specifically related to a kind of flow controller.

Background technology

So-called flow refers to: by the material quantity in a certain cross section in the unit interval, i.e. instantaneous delivery is raw at modern industry During product, flow is one of important procedure parameter, is efficiency and the important indicator of economy of weighing device, is production exercise Work and the foundation controlled, because in most industry produces, conventional measurement and control flow determine proportioning and the consumption of material Amount, it is achieved Automation of Manufacturing Process and optimized control；Simultaneously in order to carry out business accounting, it is also necessary to know such as teams and groups' stream The medium total amount crossed.So, the measurement of flow is the vital task realizing industrial processes with control.

Flow-measuring method and instrument of a great variety, sorting technique is also a lot, up to now, can industrial flow Instrument kind reaches 60 kinds more than, and the so many reason of kind is that and is much to seek one so far to any fluid, Ren Heliang The flow instrument that journey, any flow regime and any use condition are all suitable for.This 60 various flow rate instrument, every kind of product has Its specific suitability, also has its limitation, divides by measuring principle and has mechanics principle, calorifics principle, Principles of Acoustics, electricity Principle, optical principle, atomic physics principle etc..According to classification method the most popular, widest at present, i.e. it is divided into: positive displacement stream Flux of vortex street in gauge, differential pressure flowmeter, suspended body flowmeter, turbine flowmeter, electromagnetic flowmeter, fluid oscillating effusion meter Meter, mass flowmenter and inserting-type flowmeter, probe type flow meter etc..

In the technical process that rare earth extraction separates, flow-control has been one of essential condition of Rare Earth Separation.If Flow-control is accurate not, just cannot normal separation rare earth element.Cause enterprise cannot obtain high-purity rare earth product.Its product Quality Down, production cost increases.To this end, we combine the production practical situation of company, research and development one can be suitably used for deep-etching Property liquid and can in there is aggressive atmosphere normal table work effusion meter just seem increasingly important.

All kinds of effusion meters that can provide in the market have been done substantial amounts of test by us, and result all can not reach us Technological requirement.Although some can use, but its operating cost and maintenance cost are the highest, and service life is the shortest.Only The fund input of flow meter and the economic loss caused due to Equipment just reach unit up to a million.In real work we By substantial amounts of it is demonstrated experimentally that " design of corrosive liquids flow control system " that enterprise researches and develops voluntarily is can to meet completely Production requirement, after using this cover system, the product quality of my company and yield all have raising by a relatively large margin.Thorough from this The problem solving puzzlement flow control system for many years.Enterprise is made to enter the normal production order.This flow-control system System has not yet to see data and the product of open report.

By working practice in the past few years, find that all kinds of effusion meters being currently in use have the disadvantages that (1) structure is multiple Miscellaneous, bulky；(2) major part instrument and meter is only intended to the single-phase liquid of cleaning；(3) noise and shake are produced during work on the spot Dynamic: (4) install, and debug more complicated and harsh to operating environment requirements；(5) major part instrument and meter is that metal material is made , the environment with corrosive liquids and aggressive atmosphere is not adapted to work, or service life is the shortest, the control to precision It is shaped with large effect；(6) procurement price is high, and investment is relatively big, and operation and maintenance cost is higher.
