The industries such as work, water process, food and drink, pharmacy, the energy, metallurgy, paper pulp papermaking and construction material.
Complicated using raw material chemical property in chemical industry and its extraordinary production, there is corrosion to many metal materials, so to survey
Examination instrument selection causes difficulty, and existing flow is in respect of certain use limitation, and most of measuring instrumentss are due to being metal
Material, range is greatly affected.
State Intellectual Property Office disclosed a kind of Publication No. CN203385453U, patent name on 01 08th, 2014
For " anti-corrosion type balancing flow meter ".Anti-corrosion flange is installed at the two ends of anti-corrosion pipeline, and on the tube wall of anti-corrosion pipeline, interval installs two
Anti-corrosion pressure pipe, is located in anti-corrosion pipeline and installs anti-corrosion choke block, through anti-corrosion on anti-corrosion pressure pipe between two anti-corrosion pressure pipes
Anti-corrosion adaptor installed by sealing ring, anti-corrosion adaptor installs Corrosion-resistant Ball Valve through preserving and sealing circle, Corrosion-resistant Ball Valve is through preserving and sealing
Circle, anti-corrosion barrier film are arranged on the conduction hole of anti-corrosion contiguous block, and connecting pipe is installed in end count seal on the conduction hole of anti-corrosion contiguous block,
It is monolithically fabricated anti-corrosion type balancing flow meter.In that patent, the material of each part is required extremely strictly, some parts do not reach
Do not have existing in requirement for anticorrosion, or even market, producer to be looked for is particularly customized, increase cost.
Therefore in prior art, there is following technical problem：
1）Existing effusion meter measures Korrosionsmedium, is forced to use the metal material of resistant to corrosive media, due to using high
The expensive metal material of level, causes production cost higher, more because material is rare, causes material to be difficult to or manufacturing process
Special, the process-cycle very long it is impossible to meet customer need.
2）Existing effusion meter measurement Korrosionsmedium needs insulating liquid, because insulating liquid is high to installation requirement, so surveying
Accuracy of measurement is difficult to ensure that；Because insulating liquid has mobility, easily lead to insulating liquid feed line, pollution medium, and anti-corrosive properties
Medium enters rear portion, and corrosion resistant component can not cause danger.
Utility model content
This utility model aims to solve the problem that prior art problem, and proposes a kind of anti-corrosion critical speed flowmeters, adopts one
Body formed critical speed flowmeters structure, reduces the interference of differential pressure signal pipeline, thus realizing the steady of fluid measurement process route
Fixed, improve accuracy.The technical program, by being integrally formed setting, reduces gap and dead angle, had both improved the accuracy of effusion meter,
Contribute to anti-corrosion again.Meanwhile, the setting of anticorrosive coat, it is to avoid the corrosion to flow meter instrumentation for the medium, increases critical speed flowmeters
Stability and service life, realize the fluid measurement that this technology is applied to the operating mode of severe corrosive.
For realizing above-mentioned technical purpose, following technical scheme is proposed：
A kind of antiseptical critical speed flowmeters, gather measurement apparatus, described throttling arrangement including throttling arrangement data
Including valve body and be arranged on choke block on valve body, described data acquisition measuring device includes pipeline, adpting flange, pressure flange
With thermometer hole it is characterised in that：Fixed by sealing ring between described valve body, choke block；Described pipeline, adpting flange, take
Pressure flange and valve body molding；Described valve body, choke block, pipeline, adpting flange and pressure flange and medium contact surface set
There is anticorrosive coat；Described thermometer hole is arranged on pipeline, and thermometer hole is provided with anticorrosive coat with medium contact surface.
Further, described valve body is additionally provided with transmitter, transmitter lower end is connected with ball valve, and ball valve is become with valve body
Type, and ball valve is provided with anticorrosive coat with medium contact surface.
Further, described anticorrosive coat is electroplating anticorrosion layer, electrochemical anti-corrosive layer or noble gases.
Applicable media is light oil, natural gas, sulfur-containing gas, town gas, lighter hydrocarbons etc..
Medium temperature is -29 ~ 121 DEG C.
Measurement is precisely 1%.
The technical program adopt know-why be：Medium flow field produces throttling through choke block, under upstream pressure P1 is more than
About one times of pressure P2 of trip, that is, during the P1 of P2≤0.546, reaches critical gas flows.In critical gas flows, at flow velocity section minimum, medium
Flow velocity be equal to this at a temperature of medium the velocity of sound.Now, reduce throttling plate exit ambient pressure further, at all will not cause
The increase of gas yield, and increase upstream pressure, though the flow velocity at section minimum does not increase, density can be made to increase throughput and to increase
Plus.Illustrate that gas flow is unrelated with downstream pressure, be only dependent upon upstream pressure.Therefore, can be calculated using the pressure before choke block
Go out gas flow.
