Abstract
The utility model discloses a closed sampler, which comprises a sampling tube connected with a material tube and a valve installed on the sampling tube. The closed sampler is characterized in that a box body is connected at the sampling tube of the back end of the valve, and the tail end of the sampling tube is positioned in the box body. A stocker inserted in the box body is arranged on the sidewall of the box body, the part of the stocker positioned outside the box body is tubular, and a rubber plug is arranged at the end part of the stocker. The needle of an injector runs through the rubber plug, the part of the stocker positioned in the box body is a container and is arranged below the tail end of the sampling tube, and an opening is arranged above the container. The lower part of thebox body is connected with a blowdown tube. As a further improvement of the utility model, the stocker in the box body is provided with a bottom hole. The utility model has the advantages of wide application range, good safety, little environmental pollution and low cost in sampling.
Description
Technical field
The utility model relates to a kind of sampler that is used for storage tank or pipeline, belongs to the chemical plant field.
Background technology
At present in the widely used sampler of chemical field, its structure as shown in Figure 1, comprise the stopple coupon 12 that links to each other with materail tube 11, be installed on needle valve 13 and valve 14 and sampling jar 15 on the stopple coupon 12, needle valve 13 and valve 14 controls open and close and the flow sizes; During sampling, at first open two valves 13 and 14,, regulate flows to suitably big or small with needle valve 13 afterwards, collect samples with sampling jar 15 with marine store flushing discharge remaining in the stopple coupon 12.
This open sampling mode only is applicable to the security medium of conventional nonhazardous, in the middle of Chemical Manufacture, poisonous, inflammable and explosive medium is very general, for this type of medium, particularly when medium highly volatile in air, very easily hydrolysis and medium itself or its hydrolysate have equipment under the situation of strong corrosion, and traditional open sampling method has just showed very big drawback.At first, at special media sampling, open sampling has very big potential safety hazard because medium directly is exposed in the air, the personnel that very easily cause poison and or noxious material accumulates in human body; When inflammable and explosive medium contacts with air, several times have been exceeded under the likelihood ratio sealing operating mode that takes place to burn and explode, especially under the bigger situation of the frequency ratio of sampling; If medium and air reaction generate solid matter, the stopple coupon outlet of so open sampling then can be caused danger because of often stopping up.Secondly, open sampling can cause environmental pollution, and when medium had very strong volatility in air, in the process of open sampling, medium had caused environmental pollution because of being exposed to volatilizations a large amount of in the air.Once more, for strong corrosive media, open sampling meeting causes serious harm to equipment, the instrument around the sampling spot.The gas that evaporates during sampling is attached to equipment, instrument surface, and then reacts with air and etching apparatus, instrument; Form acidic materials again or attached to the medium hydrolysis on the equipment, then more aggravated the corrosion of equipment.Also has the cost height of open sampling.For the accuracy of the sample that guarantees to get, want first Open valve to bleed off during sampling by original material in the sampling arm, when flowing out, fresh material could take a sample.Open sampling is owing to the direct ingress of air of material produces hydrolysis or other reaction, so the material of releasing is all wasted.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of closed sampler is provided, it have applied widely, security good, environmental pollution is little, sampling cost low advantage.
For achieving the above object, closed sampler of the present utility model, comprise the stopple coupon that links to each other with materail tube, be installed on the valve on the stopple coupon, it is characterized in that on the stopple coupon of valve rear end, connecting a box body, the end of stopple coupon is positioned at box body, on the sidewall of box body, be provided with the material stock device that embeds box body, the material stock device is positioned at the outer part of box body to be tubulose and to be provided with plug in its end, the syringe needle of one syringe passes plug, the part that the material stock device is positioned at box body is that the top is provided with uncovered container and is in the below of stopple coupon end, and the bottom of box body is connected with drainage conduit.
During use, drainage conduit is connected with recovery system; In sampling process, Open valve, fresh material flows on the material stock device, the material stock device is the back overflow completely, " old " material flushing that will remain in earlier in stopple coupon and the material stock device is discharged, enter recovery system, needn't not worry contaminated environment and waste and subsidiary safety problem takes place because of material contacts the external world; Treat that old material arranged, after virgin material flows out, push the syringe draw samples, finish sampling after, close imported valve, material stops to flow out, whole sampling process is hedged off from the outer world fully, realized sealing, accurately sampling, and material can not wasted, can recycling, have applied widely, security good, environmental pollution is little, the low advantage of sampling cost.
As further improvement of the utility model, the material stock device in box body is provided with bottom outlet; After finishing sampling, leftover materials are discharged by bottom outlet in the material stock device, can reduce the time of the old material flushing of sub-sampling down.
In sum, the utlity model has applied widely, security good, environmental pollution is little, sampling cost low advantage.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 2, this closed sampler, comprise the stopple coupon 1 that links to each other with materail tube 9, be installed on the valve 2 on the stopple coupon 1, on the stopple coupon 1 of valve 2 rear ends, connect a box body 3, the end of stopple coupon 1 is positioned at box body 3, on the sidewall of box body 3, be provided with the material stock device 4 that embeds box body 3, material stock device 4 is positioned at the outer parts of box body 3 to be tubulose and to be provided with plug 5 in its end by end cap, the syringe needle of one syringe 6 passes plug 5, the part that material stock device 4 is positioned at box body 3 is that the top is provided with uncovered container and is in the below of stopple coupon 1 end, material stock device 4 in box body 3 is provided with bottom outlet 7, and the bottom of box body 3 is connected with drainage conduit 8.
During use, drainage conduit 8 is connected with recovery system; In sampling process, Open valve 2, fresh material flows in the material stock device 4, the 4 full back overflows of material stock device, " old " material flushing that will remain in earlier in stopple coupon 1 and the material stock device 4 is discharged, enter recovery system, needn't not worry contaminated environment and waste and subsidiary safety problem takes place because of material contacts the external world; Treat that old material arranged, new materials flow
After going out, syringe 6 draw sampless, after finishing sampling, valve-off 2, material stop to flow out, leftover materials are discharged by bottom outlet 7 in the material stock device 4, whole sampling process is hedged off from the outer world fully, realized sealing, accurately sampling, and material can not wasted, can recycling, have applied widely, security good, environmental pollution is little, the low advantage of sampling cost.
