Abstract
The utility model discloses a pipeline type fluid sampler for acquiring gaseous phase and liquid phase fluids. The pipeline type fluid sampler is mainly composed of a flange 1, a reducing adapter 2, a connecting pipe 3, an inlet valve 4, a sampling valve 6, a constant-volume sampling pipe 8 and an outlet valve 9. The flange of the sampler is directly connected with a material pipeline; during sampling, the valves at the two ends of the sampling pipe 8 are regulated to stop circulation of a medium in the sampling pipe, and an independent space is formed to facilitate sampling; a nitrogen purging connector 5 on the sampling valve 6 is connected to nitrogen, so that fluids can be prevented from condensing to block a discharge hole 7 of the sampling valve. As samples are directly obtained from the pipeline, performance parameters of the samples are more accurate.
Description
Technical field
The utility model relates to a kind of pipeline type fluid sampling thief for oil, chemical industry and the collection of circulation transportation art fluid sample.
Background technology
The memory phase of production and raw material and finished product in oil, chemical industry and circulation transportation art needs constantly to gather representative or sample singularity carries out assay.Sample has airtight and non-airtight dividing from collecting assay.Due to the characteristic of some samples, needing to reduce pressure simultaneously in gatherer process and mixing heat to collect effective sample composition.
In order to prevent that high pressure from damaging and collecting effective ingredient to the sample collector, this type of sampling request must carry out under airtight state, that is to say will reduce pressure simultaneously and keep certain high temperature.
At present direct mounted valve on pipeline for the sampling of this type of sample, direct sample.Although this mode has guaranteed the sample validity of high temperature, the potential safety hazard that its high pressure causes the sample collector.
In addition, most of sampling thiefs all are connected with processing medium import, outlet and the pipeline thereof of certain-length, and the pipeline of sampling on the one hand has a large amount of media needs displacement, and in the pipeline of sampling on the other hand, medium is at the outdoor easy condensation blocking pipeline that condenses.Simultaneously, in the pipeline outside, sampling easily causes sample condensation in valve to condense later, stops up Sampler valves due to valve.
The purpose of this utility model is exactly in order to address the above problem.
The utility model content
The utility model pipeline type fluid sampling thief is achieved through the following technical solutions:
Be used for gathering the pipeline type fluid sampling thief of gas phase, liquid phase fluid, it mainly is welded to connect by flange 1, reducing adapter 2, connecting pipe 3, admission valve 4, sampling valve 6, constant-volume sampling pipe 8, outlet valve 9 etc. the sample devices that forms.
Admission valve 4, sampling valve 6, outlet valve 9 are the metal needle valve.
Sampling valve 6 is with nitrogen blowing interface 5 and discharging opening 7.
Admission valve 4 lower ends, outlet valve 9 lower ends and constant-volume sampling pipe 8 two ends are welded to connect; Sampling valve 6 lower ends are welded on constant-volume sampling pipe 8 middle parts; After constant-volume sampling pipe 8 and admission valve 4 lower ends, outlet valve 9 lower ends, sampling valve 6 lower ends connect, with connecting pipe 3 welding, last connecting pipe 3 two ends and reducing take over 2 welding, reducing take over 2 and flange 1 integrally welded.
Sampling thief two end flanges 1 directly are connected with the material pipeline, regulate sampling pipe 8 two ends admission valves 4 and outlet valve 9 during sampling, circulate in sampling pipe to stop medium, form an independently space, are convenient to sampling.Nitrogen blowing interface 5 on sampling valve 6 connects nitrogen, the interior medium of sampling valve 6 can be purged totally, can prevent from that medium fluid from condensing to stop up sampling valve 6 discharging openings 7.
That the utility model pipeline type fluid sampling thief has is quick for installation, the position flexibly, sampling rapidly, advantage accurately, also can realize online sampling simultaneously.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model, and the each several part title is as follows:
Flange 1, reducing adapter 2, connecting pipe 3, admission valve 4, nitrogen blowing interface 5, sampling valve 6, thief hatch 7, constant-volume sampling pipe 8, outlet valve 9.
Concrete implementation
Be elaborated below in conjunction with 1 pair of the utility model of accompanying drawing.
Be arranged on diameter and be the pipeline type fluid sampling thief on the DN40 pipeline, its mainly by DN40 flange 1, DN50 * 40 reducings take over 2, DN50 connecting pipe 3, DN20 pin type admission valve 4, DN20 pin type sampling valve 6, DN25 constant-volume sampling pipe 8, DN20 pin type outlet valve 9 etc. are welded to connect the sample devices that forms.
DN20 pin type sampling valve 6 is with Φ 8 nitrogen blowing interfaces 5 and Φ 10 discharging openings 7.
Admission valve 4 lower ends, outlet valve 9 lower ends and constant-volume sampling pipe 8 two ends are welded to connect; Sampling valve 6 lower ends are welded on constant-volume sampling pipe 8 middle parts; After constant-volume sampling pipe 8 and admission valve 4 lower ends, outlet valve 9 lower ends, sampling valve 6 lower ends connect, with connecting pipe 3 welding, last connecting pipe 3 two ends and reducing take over 2 welding, reducing take over 2 and flange 1 integrally welded.
Sampling thief two ends DN40 flange 1 directly is connected by bolt with DN40 material pipeline, regulates pin type admission valve 4 and the outlet valve 9 at sampling pipe 8 two ends during sampling, circulates in sampling pipe to stop medium, forms an independently space, is convenient to sampling.Nitrogen blowing interface 5 on sampling valve 6 connects nitrogen pipelines, passes into nitrogen and the interior medium of sampling valve 6 can be purged totally, can prevent from that medium fluid from condensing to stop up sampling valve discharging opening 7.
