Abstract
The utility model discloses a simple device for gas purity determination. The simple device comprises a small-size bottle body for holding a gas absorbing solution and a high-accuracy needle cylinder for extracting to-be-determined gas, wherein a silicon pad and a metal nut are arranged on the small-size bottle body; a bottle cap is composed of the silicon pad and the metal nut; the silicon pad is closely pressed on the opening of the small-size bottle body by the metal nut; a needle head is arranged at one end of the needle cylinder; an exhaust pipe is also arranged on the silicon pad; the capacity of the small-size bottle body is 25-250ml; the accurate scale of the high-accuracy needle cylinder is 1ml; and any one needle cylinder with the scale of 1-5ml is optional. By adopting the technical scheme, the device disclosed by the utility model has the following advantages that as each part of the device is small, the device is small in overall size so as to be convenient for carry; as the high-accuracy needle cylinder is adopted to measure the gas, the device is easy to operate; and simultaneously, as all the parts are easily bought on the market, the device is low in cost.
Description
Technical field
The utility model belongs to measurement mechanism, relates in particular to a kind of a kind of device of measurement gas purity.
Background technology
When current PVC industry is measured purity acetylene, utilize N, dinethylformamide absorbs the characteristic of acetylene, adopt Orsat apparatus to measure 100ml gas to be measured, with the water in the tubualted bottle gas is driven in the absorption tube, make gas and DMF effect, reduce to determine the purity of acetylene according to the volume after the effect.When measuring vinyl chloride purity, adopt same principle, absorb with terebinthina; When measuring oxygen content, absorb with pyrogallic acid potassium.Because the Orsat apparatus volume is larger, analysis time is relatively long, and generally is placed in the laboratory, is unfavorable for on-the-spot local operation and the simplification of doing the sample process.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency provides a kind of gas purity to measure easy device, and this device is easy to carry, easy to use and cost is low.
For achieving the above object, the utility model is by the following technical solutions:
A kind of gas purity is measured easy device, comprise the small size bottle of dress gas absorption solution and be used for extracting the syringe of the pinpoint accuracy of gas to be measured, silicagel pad and metal nut are housed on the small size bottle, metal nut and silicagel pad consist of bottle cap, metal nut is pressed on silicagel pad on the bottleneck of small size bottle, and the syringe end is provided with syringe needle.
Above-mentioned gas purity testing easy device also is provided with gas outlet on silicagel pad.
Above-mentioned gas purity testing easy device, small size bottle capacity is 25-250ml, and the exact scale of pinpoint accuracy syringe is 1ml, and selecting scale is arbitrary syringe among the 1-5ml.
Adopt technique scheme, the utility model has following advantage: because all parts of the present utility model is little, overall volume is less, be easy to carry, owing to adopt the pinpoint accuracy syringe to measure gas, easily operation, these parts all buy in market easily simultaneously, and cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view that the small size bottle of silicagel pad and metal nut is housed.
Embodiment
A kind of gas purity is as depicted in figs. 1 and 2 measured easy device, comprise the small size bottle 1 of dress gas absorption solution and be used for extracting the syringe 4 of the pinpoint accuracy of gas to be measured, silicagel pad 2 and metal nut 3 are housed on the small size bottle, metal nut 3 and silicagel pad 2 consist of bottle cap, metal nut 3 is pressed on silicagel pad 2 on the bottleneck of small size bottle 1, and syringe 4 ends are provided with syringe needle 6.
The utility model also is provided with gas outlet 5 on silicagel pad 2, gas outlet has the effect of balance external and internal pressure.
The utility model small size bottle capacity is 25-250ml, and the exact scale of pinpoint accuracy syringe is 1ml, and selecting scale is arbitrary syringe among the 1-5ml.
The course of work of the present utility model is as follows: during use, extract gaseous sample to be measured with the syringe with syringe needle, syringe needle is pricked in the small size bottle that gas absorption solution to be measured is housed by silicagel pad, be inverted simultaneously, make a little gas absorption liquid be drawn into syringe, utilize the volume change after absorbing to record gas purity.
The below is the test process of concrete gas: such as acetylene
The small size bottle is selected the 25ml bottle, and the DMF of the 20-23ml that packs in the bottle after the silicagel pad, is tightened metal nut on the pad, and inserted gas outlet in silicagel pad; Then with extracting the acetylene gas sample with the 1ml syringe of syringe needle, repeatedly replace 2～3 times after, accurately extract 1ml; Syringe needle is pricked into bottle by silicagel pad, be inverted bottle this moment, spur gently cylinder piston, make a little N, dinethylformamide enters syringe, then rock whole device, observe the volume that is not full of by solution, then purity acetylene is: (volume that 1-is not full of by solution) * 100%.
When the in-built terebinthina of this device small bottle body, can survey the purity of vinyl chloride.
When the in-built pyrogallic acid potassium of this device small bottle body, can survey the purity of oxygen level.
