Inert gas shielding branch, a related glass sampling bottle for having branch pipe of the pressure-resistant emulsion tube of port.Alkyl aluminum, alkylaluminoxane
Very sensitive to air and moisture, the operation for being related to such product has been required to inert gas (N2, Ar) protection.This method behaviour
Make cumbersome, connecting portion is more, increases risk of leakage, and risk is larger in sampling process.Therefore, a kind of both corrosion resistants are designed and produced
The sampling instrument lose, be hardly damaged, is highly-safe, being convenient for carrying carries out periodic analysis for product in production process or intermediate product
Detection is crucial quality control and the adjustment of technique.
Utility model content
In view of the above-mentioned problems, the utility model provides the liquid sampling dress under the inert atmosphere protection of safe and convenient a kind of
It sets.
To achieve the above object, the technical solution adopted in the utility model is：A kind of liquid under inert atmosphere protection takes
Sampling device is made of sampler, four-way pipe, valve, sealing dottle pin, and sampler one end is connected by pipeline with sample tap, pipeline
Upper setting valve；The sampler other end is connect with four-way pipe axial passageway, and junction sets the first sealing dottle pin；Four-way pipe is axially logical
Road top setting sampling cap and the second sealing dottle pin, sampling cap centre are equipped with hole；The external inert atmosphere of the radial line of four-way pipe
Protective device, junction set third sealing dottle pin.The external inert atmosphere protection device of four-way pipe, facilitates and fills to the inside of four-way pipe
Inert gas improves safety when sampling；Sealing dottle pin facilitates the taking-up of liquid after sampling convenient for penetrating.
Graduation mark is provided on the lateral wall of sampler.Graduation mark, which facilitates, records taken liquid capacity when sampling, and passes through quarter
Spend the sampling of the different sampling specifications of progress of the line property of can choose.
Valve connects sampling head, and sampling head is in section cone, and upward, section is conical for the portlet of section cone
Portlet connecting valve.Sampling head in section cone, upper port diameter be less than lower port diameter, facilitate heterogeneity liquid into
Sample keeps sampling more accurate.
It samples cap and is located at the second sealing dottle pin top.
First sealing dottle pin, second sealing dottle pin and third sealing dottle pin use with can puncture anti-corrosive rubber material
Matter.
Operating procedure when fluid sampling device under inert atmosphere protection samples：
The air-tight test of sampler：First sampler is external on the pipeline of inert atmosphere protection device, is filled with inertia
Gas checking air-tightness.
The displacement and charging of sampler：Sampler to be pumped into negative pressure, opens valve, liquid material flows directly into sampler,
With inert gas purge sample tap to material remaining between valve, valve is closed, sampling terminates.
Liquid sampling：Four-way pipe radial line is passed through inert gas, by the sampled cap of the syringe needle of sampling probe along four-way pipe axis
It is inserted into sampler to pipeline, extracts quantitative liquid sample；Syringe needle, which retracts, after sampling enters in four-way pipe radial line, then is pumped into one
Quantitative inert gas makes syringe needle form gas embolism, syringe needle is fully drawn out and completes sampling process.
Compared with prior art, the utility model is had the advantages that：
Apparatus structure is simple, samples quick and safe and easy to carry；Device good seal performance, without leakage in sampling process,
It does not waste；Device liquid sample can be stored temporarily, guarantee sample trackability, selective examination, check convenient for sample, especially suitable in life
