The through-hole 33 that inner cavity is connected, the position of two through-holes 33 is corresponding, and the relative position by adjusting embolism 32 and valve body 31 is closed
The amount of liquid is drawn in system's control from pipette 4.
Further, 31 inner surface of valve body is equipped with internal screw thread, and 32 outer surface of embolism is equipped with and the internal screw thread in valve body 31
The external screw thread matched is realized by adjusting the degree of communication of the extent control valve body 31 in the screw-in valve body 31 of embolism 32 in-between
Draw the control of amount of liquid.
Further, a through-hole is provided on the embolism 32, embolism 32 and the cavity shape of valve body 31 are adapted, embolism
32 fill in valve body 31, when the through-hole of embolism 32 just towards the through-hole 33 of valve body 31 when, liquid can pass through valve body 31 and embolism
32, when embolism 32 rotate 90 ° of valve bodies 31 through-hole 33 blocked by embolism 32 when, liquid cannot by valve body 31 and embolism 32,
The control for drawing amount of liquid is realized by the degree of correspondence that rotation embolism 32 adjusts the through-hole on through-hole and valve body 31 on embolism 32
System.
Further, the compressing gasbag 1 is integrally formed with suction pipe 2, makes better tightness, is not easy gas leakage, is also more convenient.
Present invention work application method: it when starting to draw liquid, allows piston valve gear 3 to be in open state, makes suction pipe 2
Then connection up and down squeezes compressing gasbag 1, after excluding air, pipette 4 is satisfied with the suction of ear washing bulb by closure piston valve gear 3
On 2 lower section of pipe, starts slowly to open piston valve gear 3, increase under stress liquid, after reaching required dosage fastly, slowly
Closure piston valve gear 3 reaches required liquid level.
