Preferably, the cock body two cooperates with the air inlet pipe.
(3) beneficial effect
Due to using above-mentioned technical solution, the beneficial effects of the utility model are:
Cock body one and air inlet pipe cooperate, and remain in air inlet pipe without air, reduce in traditional acquisition method residual air to knot
The influence of fruit.
In use, opening motor, motor drives cord to wind on output shaft side wall, and piston is along sampling pipe inner body wall
Upward sliding, cock body one are detached from air inlet pipe, and air is entered in sampling tube body by air inlet pipe, the water of top land from outlet pipe into
Enter collector pipe, collector pipe and outlet pipe are to be symmetrical set, and collection efficiency are enhanced, by the volume phase of water in two collector pipes
The volume of air being collected into can be calculated by adding, simple to operate, and design is reasonable.
After air trapping, cooperated using cock body two and air inlet pipe, avoids the air being collected into from being discharged, improve detection
As a result accuracy.
