Specific implementation mode
The specific embodiment of the utility model is described in further details below in conjunction with attached drawing, it is noted that
Embodiment is only further elaborated on the utility model, is not construed as the restriction to the utility model.
The liquid automatic sampling pipe of the utility model, including tube body 1 and sampling mouth 2, interior be equipped with of tube body 1 connect with sampling mouth 2
Logical probe tube 3 is additionally provided with thief rod 4 in tube body 1, and the inner end of thief rod 4 is equipped with sampling plug 5, and sampling plug 5 can be in thief rod
Inner wall under 4 drive along tube body 1 moves, and the outer wall of sampling plug 5 is connect with the inner wall sealing of tube body 1, and this sealed connection can
It is realized in the form of by being arranged sealing ring on sampling plug 4.
The cavity that probe tube 3 penetrates can be accommodated by being equipped in thief rod 4, the outer wall of probe tube 3 and the inner wall of the cavity it
Between there is the first gap 6, there is the second gap 7, sampling plug 5 to be leaned on tube body 1 between the upper end of probe tube 3 and the bottom of the cavity
Between the inner wall of one end of nearly sampling mouth 2 there is third space 8, the first gap 6, the second gap 7 and third space 8 to form negative pressure
Imbibition channel, this negative-pressure liquid suction channel are also to be connected to sampling mouth 2, when sampling mouth 2 is extend into sampling liquid, are reduced
