The utility model proposes a kind of sampler 100.

Reference picture 1, Fig. 1 are the structural representation of the embodiment of the utility model sampler one.

In the utility model embodiment, the sampler 100, including be connected to material pot A sampling pipe 10 and set In the first ball valve 20 of the sampling pipe 10, the sampling pipe 10 is further opened with liquid taking port 13, first ball valve 20 Between liquid taking port 13 and material pot A, the sampler 100 also includes sealing the sealing 30 of the liquid taking port 13 and taken Sample syringe 40, the sampling injector 40 are sampled through the sealing 30, into the sampling pipe 10.

Technical solutions of the utility model set sampler 100, sampling dress in the side wall for containing the material pot A of electrolyte Putting 100 includes sampling pipe 10 and the first ball valve 20 located at the sampling pipe 10, and liquid taking port 13 is offered on sampling pipe 10, And the liquid taking port 13 is sealed by sealing 30, avoid air from entering.When being sampled, open the first ball valve 20, electrolyte by Material pot A enters in sampling pipe 10, and sampling injector 40 draws electricity through the sealing 30 into the sampling pipe 10 Liquid is solved, completes sampling, whole sampling process carries out in a sealed meter environment, avoids electrolyte and air contact and reacts, just Just it is quick.

For ease of sampling, the supervisor 11 of the sampling pipe 10 is convexly equipped with branch pipe 12, the branch pipe 12 and the supervisor 11 Connection, the one end of the branch pipe 12 away from the supervisor 11 form the liquid taking port 13.

The sealing 30 includes plug and cushion, and the plug offers through hole, and the cushion is contained in the through hole, The plug is contained in the branch pipe 12 and seals the liquid taking port 13.

The cushion is ethylene propylene diene rubber or fluorubber, can effectively prevent the corrosiveness of electrolyte.

The sampler 100 also includes the venting ball valve 50 located at the supervisor 11, and the branch pipe 12 is located at the row Between balloon valve 50 and first ball valve 20, the venting ball valve 50 is used to exclude the air in sampling pipe 10.
