Liquid chlorine sampling liquid chlorine sampling liquid chlorine sampling cylinder liquid chlorine sampling cylinder
Main technical indexes of liquid chlorine sampling cylinder:
1, working pressure: 2Mpa;
2, working temperature: -40~80;
3, material: stainless steel;
4, specifications: 300ml, 500ML, 1000ML, 2000ml, 2500ml, 4000ml, 5000ml.
The liquid chlorine sampling cylinder can be sampled on the large liquid chlorine cylinder or the liquid chlorine pipeline, and is also suitable for the collection of toxic chemical liquefied gas products
1, when sampling with a double tube bottle connected double valve, the valve in the bottle head corresponding to the long tube and the short tube on the logo should be ready.
2, flushing tube and liquid chlorine sampling steel cylinder: liquid chlorine sampling cylinder into the sampling port line, each connection shall be tight. Sufficient flushing of the material to be used by opening or closing the control valve and the discharge valve. Through open or close the control valve and the discharge valve and the valve fully into the washing liquid chlorine sampling cylinders, the cylinder of liquid chlorine sampling before processing, can be connected to the vacuum discharge valve on the appropriate vacuum pumping system, in order to facilitate smooth flushing.
3, after washing the single valve connected to the vacuum discharge by sampling the cylinder valve on the appropriate vacuum pumping system, through open or close the control valve and into the valve in full liquid sample, double valve type flushing after sampling cylinder by opening or closing the valve into the valve control, and the outlet valve in full liquid sample.
Sampling method of liquid chlorine sampling steel cylinder: use double inner tube with a bottle of liquid chlorine cylinder double valve head connected, according to the short tube length calculated, recoverable reserve volume of liquid chlorine cylinder volume 12%~15% of liquid sample.
Note:
1, sampling safety requirements, sampling personnel should be familiar with the potential dangers of various liquefied petroleum gas and safety technology. Sampling to prevent explosion, fire, suffocation, poisoning, corrosion, frostbite and other accidents.
2, sampling, sampling cylinders can not be filled, usually only installed to 80% of its volume, to prevent the low boiling point of the sample components and volatile impurities into the sample.
3, sampling area should be well ventilated, away from fire. The sample with the sample should be protected from high temperature, exposure to the sun, and stored in a cool place.
4, the sampling of liquefied gas cryogenic liquid hydrogen, helium, application of special sampler
