The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
As shown in Figure 1, a kind of vacuum extractor described in the utility model comprises bottle 10, be located at the bottle cap 12 on the bottle 10, being fixed at suction valve on the bottle cap 12 by attaching nut 6, also is bottle 10, and bottle cap 12 and suction valve consist of this utility model agent structure.
Described suction valve comprises valve body 2 and the valve gap 13 of being located at valve body 2 one ends, forms valve pocket 5 in the described valve body 2, and described valve body 2 other ends are provided with vacuum tube joint 3, and vacuum tube joint 3 stretches in the valve pocket 5.Be communicated with by siphunculus 11 between described valve pocket 5 and bottle 10 inner chambers, siphunculus 11 stretches into bottle 10 interior intracavity.Described valve gap 13 is provided with suction catheter joint 7, and suction catheter joint 7 is communicated with bottle 10 inner chambers by vertical tube 8.That is to say, vacuum tube joint 3 and suction catheter joint 7 all are communicated with valve pocket 5 and bottle 10 inner chambers.
Be provided with spool 18 in the described valve pocket 5, described spool 18 and vacuum tube joint 3 stretch into the corresponding setting of an end in the valve pocket 5, and in other words, described spool 18 can open and close vacuum tube joint 3.Described valve gap 13 is provided with through hole, be provided with valve rod 14 in the through hole, be arranged with rotation hand wheel 16 outside the described valve rod 14, rotation hand wheel 16 is threaded with valve gap 13, be provided with the first spring 17 between described valve rod 14 and the spool 18, be provided with the second spring 15 between described valve rod 14 and the rotation hand wheel 16.This utility model can be regulated the technical purpose that rotation hand wheel 16 reaches opening and closing vacuum tube joint 3 by rotation.
The end end that described siphunculus 11 stretches into bottle 10 interior intracavity is connected with ball float 9, and when bottle 10 inner chamber liquid levels were higher, ball float 9 floating sealing siphunculus 11 were in order to avoid body fluid seals in the valve pocket 5.
