Abstract

The utility model relates to a sampling barrel, mainly aiming at solving the problems of difficult cleaning, frangibility, no qualified sampling and environment pollution in the prior sampling tools. The utility model is characterized in the upper and lower end of a glass tube (1) are respectively fixed with an upper and a lower pressing cup (2, 3) with a main pole (4) passing through and with a vent hole (12) and plurality of the oil holes (11); a seal (7) contacted with the inner wall of the lower pressing cup (3) is fixed on the main pole (4); the main pole (4) and the upper end of a guide rod (5) fixed with the upper pressing cup (2) are respectively fixed at the upper and lower opening end of a spring clamp (6). The utility model has the advantages of simple and practical operation, sampling standard, easy dismantle, non frangibility and easily washing and cleaning.

Description

Sampler barrel

Technical field:

The utility model relates to the used barreled liquid oils of liquid oils detection range materials instrument, especially sampler barrel.

Background technology:

The many formulas of liquid oils sampler are various in all trades and professions at present, barreled liquid oils sampler is also a lot, sampling was generally taken a sample with glass tube or glass stopple coupon from oil drum in the past, entered a glass tube part putting into oil drum bottom process oil drum upper part oil, when particularly getting bucket bottom oil, the sample of being got is not real bottom oil, do not reach the purpose of getting bucket bottom oil, and when shifting, on these two kinds of glass tubes, air is arranged all, can not reach sealing fully, oil sample is trickling always, also causes unnecessary waste in the time of contaminated environment; In addition, because glass tube is elongated, make its frangible and cleaning difficulty.

The utility model content:

Clean deficiency difficult, frangible, that sampling does not reach requirement and contaminated environment in order to overcome existing sampling instrument, the utility model provides a kind of sampler barrel, this sampler barrel have practicality simple to operate, sampling standard, convenient disassembly, non-friable, be convenient to the characteristics cleaning and clean.

The technical solution of the utility model is: this sampler barrel comprises glass tube, the glass tube upper and lower side respectively with passed by mobile jib and have the upper and lower pressure cap of air hole and some oilholes to fix respectively; Be fixed with the oil sealing that touches mutually with the lower pressing cap inwall on the mobile jib, the upper end that mobile jib reaches the guide rod of fixing with upper pressing cap is separately fixed at spring clamp two openends up and down.

Above-mentioned mobile jib bottom has nut; Oilhole on the lower pressing cap is 6; Glass tube and upper and lower pressure cap are by being threaded.

The utlity model has following beneficial effect: since take such scheme on mobile jib, be fixed with the oil sealing that touches mutually with the lower pressing cap inwall, with preceding elder generation dop spacing about the spring clamp is adjusted into 5-10mm, make oil sealing and lower pressing cap good seal, when getting barrel bottom sample, be unlikely to make the sample on barrel top also to enter in the sample bucket, and in the sample transfer process, do not flow out, environmental protection is not wasted again, and glass tube is threaded with upper and lower pressure cap, have practicality simple to operate, sampling standard, convenient disassembly, non-friable, be convenient to the characteristics cleaning and clean.

Description of drawings:

Fig. 1 is a structure cut-open view of the present utility model.

1-glass tube among the figure, 2-upper pressing cap, 3-lower pressing cap, 4-mobile jib, 5-guide rod, 6-spring clamp, 7-oil sealing, 8-0 type circle, 9-nut, 10-packing ring, 11-oilhole, 12-air hole, 13-nut, 14-accumulator.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By shown in Figure 1, this sampler barrel comprises glass tube 1, glass tube 1 upper and lower end is fixed upper and lower pressure cap (2,3), and upper and lower pressure cap (2,3) has 1

air hole

12 and 6 oilholes 11 respectively, can keep accumulator 14 interior atmospheric pressure to equate with external atmosphere pressure, oil sample enters thus and discharges when being convenient to take a sample, and glass tube 1 can directly estimate, see and look into convenience, non-friable for the transparent organic glass pipe; Upper and lower pressure cap (2,3) is built-in with sealing zero type circle 8, makes sealing better, and upper and lower pressure cap (2,3) and glass tube 1 can be by being threaded, and this connected mode convenient disassembly, is convenient to cleaning; Pass on the mobile jib 4 of upper and lower pressure cap (2,3) and be fixed with the oil sealing 7 that touches mutually with lower pressing cap 3 inwalls, set nut 13 and packing ring 10 are arranged on the oil sealing 7, oil sealing is sealed the oilhole on the lower pressing cap 3, when sampler barrel being put into the oil drum bottom, the top oil sample can not enter sampler barrel, reaches the requirement of sampling; Fix a guide rod 5 with nut on the upper pressing cap 2, the upper end that the bottom has the mobile jib 4 of stop nut 9 and a guide rod 5 is fixed on spring clamp two openends about in the of 6 with nut respectively.

During actual the use, earlier with spring clamp 6 about the dop spacing be adjusted into 5-10mm, make oil sealing 7 and lower pressing cap 3 good seals, adjustment mobile jib 4 lower end nuts 9 make it with lower pressing cap 3 distances from bottom be that 10-20mm gets final product; Sampler barrel is inserted the oil drum bottom, pushing down upper handle 15 holds lower handle 16 simultaneously and by guide rod 5 accumulator 14 is moved down, oilhole 11 on the lower pressing cap 3 is separated with oil sealing 7, oil just enters accumulator 14 from oilhole 11, air in the accumulator 14 is discharged from upper pressing cap 2 air holes 12 simultaneously, unclamp lower handle 16 and make oil sealing 7 seal oilhole 11 on the lower pressing cap 3 after accumulator 14 is full of oil sample, oil sample can not flow out; In like manner can produce oil sample.

This shows that this sampler barrel utilizes the principle of fluid connection device can be easily the oil in the oil drum bottom to be taken out and transfer in the sampling jar, and reached practicality simple to operate, sampling standard, convenient disassembly, non-friable, be convenient to the characteristics cleaning and clean.
