A kind of on-line sampler fast
Technical field
The utility model belongs to technical field of petrochemical industry, relates to a kind of sampler, particularly relates to a kind of on-line sampler fast.
Background technology
The analytical sampling of conventional petroleum chemical plant installations medium, need put in sampling bottle by required sample by thief hatch, and institute's sample thief is continuously not representative, and many media have the character such as poisonous, inflammable, high temperature, there is high risk.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provide a kind of easy to operate, safe and reliable, efficiency is high, can the quick on-line sampler of material and publicity actual conditions in reacting pipe or equipment.
The technical scheme taked for realizing above-mentioned utility model object is:
A kind of on-line sampler fast, it is characterized in that: comprise sample collection groove, sample collection storehouse, breakout box, sampling jar and air drive device, one end, sample collection storehouse is arranged on medium pipeline by flange, the other end is connected with air drive device, and bottom is the sample collection funnel of inverted trapezoidal; Described sample collection groove is connected with the slide plate being positioned at sample collection storehouse; Described sampling jar connects sample collection funnel by breakout box, arranges Vacuum ball valve between breakout box and sample collection funnel; Described air drive device is controlled by gearing operation valve, and gearing operation valve connects gas pressure regulating valve, stop valve, air intake cutting ferrule successively by pipeline, is provided with tensimeter between gearing operation valve and gas pressure regulating valve;
The length of described sample collection groove is 1/2 of medium pipeline diameter.
Quick on-line sampler structure of the present utility model is simple, easy to use, various medium under being applicable to fail to understand situation to the state of arts in pipeline in oil, chemical plant installations, in the harmfulness such as especially poisonous, inflammable, explosive, the No leakage sampling of low pressure gas, liquid medium.
Quick on-line sampler of the present utility model ensure that continuity and the representativeness of sampling process, and institute's sample thief represents the time of day of whole system; Sampling process seals, effectively prevent the medium such as poisonous, harmful, inflammable to the injury of operator, ensureing institute's sample thief by extraneous secondary pollution, avoiding the peril that inflammable, explosive medium may cause when sampling, handling safety is reliable, is applicable to various cryogenic liquid medium.

Embodiment
The quick on-line sampler of one of the present utility model, comprise sample collection groove 1, sample collection storehouse 4, breakout box 7, sampling jar 8 and air drive device 9, one end, sample collection storehouse 4 is arranged on medium pipeline by flange 3, the other end is connected with air drive device 9, and bottom is the sample collection funnel of inverted trapezoidal; Sample collection groove 1 is connected by lever 5 with the slide plate 2 being positioned at sample collection storehouse 4; Sampling jar 8 connects sample collection funnel by breakout box 7, arranges Vacuum ball valve 6 between breakout box 7 and sample collection funnel; Air drive device 9 is controlled by gearing operation valve 10, gearing operation valve 10 connects gas pressure regulating valve 12, stop valve 13, air intake cutting ferrule 14 successively by pipeline, be provided with the tensimeter 11 measuring pressure between gearing operation valve 9 and gas pressure regulating valve 12 pipeline, the length of sample collection groove 1 is 1/2 of medium pipeline diameter.
During sampling, air drive device 9 promotes sample collection groove 1 by lever 5 and enters in medium pipeline, random collecting dielectric sample, sample collection groove 1 is returned in sample collection storehouse 4 by lever 5 by sample collection well rear air drive device, sample collection groove 1 is overturn by lever 5, make dielectric sample enter breakout box 7 by the sample collection funnel bottom sample collection storehouse 4 by Vacuum ball valve 6, slowly flow in sampling jar 8, realize once complete sampling.The power control of air drive device 9 regulates air mass flow and flow velocity to realize by gearing operation valve 10, tensimeter 11, gas control valve 12, stop valve 13 etc.
