Probe tube upper end is set as bend pipe can prevent upper layer in liquid sleeve pipe when carrying out extraction liquid using draw-out device
In space.
It is further preferred that diaphragm is arranged with baffle contacts face in the probe tube, liquid sleeve pipe is further prevented
It is interior.
It is further preferred that the sample injector further includes holder, the holder by upper bracket, bottom bracket and by upper bracket,
The montant of bottom bracket connection is constituted, and from sample-adding bottom of bottle portion will be loaded bottle holder, casing is clamped the upper bracket bottom bracket,
Link into an integrated entity to which bottle and draw-out device will be loaded using holder, when be loaded hold high-temp liquid in bottle when convenient for hand-held progress
Sampling.
The beneficial effects of the utility model are：The utility model is right using protrusion by the way that protrusion is arranged on internal surface of sleeve pipe
Elastic tape sliding distance is limited to achieve the purpose that carry out quantitative sampling, simple in structure, easy-to-use, can be accurate
Control sampling amount；Further setting holder links into an integrated entity bottle is loaded with draw-out device, convenient for holding high-temperature liquid in sample-adding bottle
Sampling is held when body.
