Description
Technical field
The utility model relates to a kind of mancarried device of collection liquid in the chemical plant installations, particularly collection, the interim storage of the flammable and combustible liquids such as aluminum alkyls and alkylaluminoxane in production and use procedure.
Background technology
Aluminum alkyls, alkylaluminoxane are very responsive to air and moisture, and the operation that relates to this series products needs that all inert gas (N is arranged
2, Ar) protection.At present, off-line sample sample mode is to connect three-way pipe at sample tap, and a port is the inert gas shielding branch road, and port is with the related glass sampling jar that arm is arranged of withstand voltage emulsion tube.The method complex operation, connecting portion is many, increases risk of leakage, and danger is larger in the sampling process; Sample is difficult for storage, needs after the sampling to analyze immediately.And product or middle product periodic analysis detection in the production run is most important to the adjustment of quality control and technique.
Summary of the invention
The purpose of this utility model provides a kind of for liquid sampling, sample storage device, has portable, safe characteristics.
To achieve these goals, the utility model is taked following technical scheme: a kind of portable fluid sampling, sample storage device, it is characterized in that device mainly is comprised of sample storage device, four-way piece, valve, sealing dottle pin, described sample storage device 1 one ends link to each other with sample tap by pipeline, and valve 3 is set on the pipeline; Sample storage device 1 other end is connected with the axial passageway of four-way piece 2 by the road, and sealing dottle pin 4 is established in the junction; Four-way piece 2 axial passageway tops are provided with sampling cap 5 and sealing dottle pin 6 successively, are provided with the hole in the middle of the sampling cap 5; The external inert gas of the radial line of four-way piece 2.
Described sample storage device can according to the collected specimens amount, be prepared into the container of all size in advance; But the sealing dottle pin is the anti-corrosive rubber material with puncture, such as silicon rubber, fluororubber.
For the replacing that makes things convenient for device feature and carry, the further preferred embodiment of the utility model adopts metal material, and each connecting portion is threaded connection.
Use main points of the present utility model comprise:
1. the air-tight test of sample storage device: first the sample storage device is external on the inert gas pipeline, is filled with inert gas and checks impermeability.
2. the displacement of sample storage device and charging: the sample storage device is pumped into negative pressure, opens sample storage device valve, liquid material flows directly into the sample storage device, and to material remaining between the valve, valve-off is taken a sample and finished with the inert gas purge sample tap.
3. liquid sampling: the four-way piece radial line passes into inert gas, and the syringe needle of sampling probe is inserted the sample storage device through the axial pipeline of sampling shade four-way piece, extracts the quantitative liquid sample; The syringe needle rollback enters in the four-way piece radial line after the sampling, and a certain amount of inert gas of suction makes syringe needle form gas embolism again, syringe needle is extracted out fully finished sampling process.
The utility model compared with prior art has the following advantages:
1. apparatus structure is simple, sampling quick and safe and easy to carry;
2. the device good seal performance without revealing, is not wasted in the sampling process;
3. device liquid sample can be stored temporarily, guarantees the sample trackability, is convenient to selective examination, the check of sample, is specially adapted to the analyzing and testing link of flammable and combustible liquids in production and use procedure.
