The local of described valve core rod 502 is positioned at outside guide holder 503, to obtain larger stroke.
Be normally off between described lower valve base 510 and bottom spool 509.
Embodiment 1:
As in Fig. 2, a kind of microsample valve, be provided with valve core rod 502 in valve body 501, valve core rod 502 upper end is provided with the upper valve core 505 be sealed and matched with upper valve base 504, valve core rod 502 lower end is provided with the bottom spool 509 be sealed and matched with lower valve base 510, and valve core rod 502 is also provided with spring 506.Spring 506 in this example makes upper valve core 505 and upper valve base 504 be in normally off, the patient of the user such as postoperative xerostomia of row anesthesia, by the mode of sucking, then to overcome spring force descending for upper valve core 505, open between spool 505 and upper valve base 504, now can liquid make-up, but as continued to suck, then formed between bottom spool 509 and lower valve base 510 and be sealed and matched, again suck after needing stopping to suck rear valve core reset such as grade and could continue liquid make-up, thus achieve the liquid make-up of trace controllably, even and if microsample valve deviate from and also can not pollute sheet.Still be not suitable for again the patient of a large amount of moisturizing for moisturizing profit lip in this example, but the device in this example also may be used for the treatment of comfort type, such as supplement milk or a small amount of sugar liquid to baby, also may be used for the some diseases needing slow release treatment, such as, need the oral ulcer etc. of slow release treatment.
Embodiment 2:
As shown in Fig. 3, Fig. 4, a kind of microsample valve, be provided with valve core rod 502 in valve body 501, valve core rod 502 upper end is provided with the upper valve core 505 be sealed and matched with upper valve base 504, valve core rod 502 lower end is provided with the bottom spool 509 be sealed and matched with lower valve base 510, and valve core rod 502 is also provided with spring 506.Position near lower valve base 510 on valve body 501 is provided with flexible bags 511, valve body 501 in flexible bags 511 is provided with multiple chute 508, strut 4 is arranged in chute 508, strut 4 lower end is connected with chute 508 lower end or flexible bags 511, and the other end is by block 507 or be directly connected with valve core rod 502.
Be normally off between described lower valve base 510 and bottom spool 509.
In this example, by the structure of flexible bags 511 and strut 4, thus the microsample valve in this example can have more control mode.Such as, by backing down bottom spool 509, the sealing between lower valve base 510 and bottom spool 509 can be opened, being sealed and matched until valve core rod 502 drives upper valve core 505 and upper valve base 504 to be formed.Thus realize micro-liquid make-up.Or by the mode of sucking, flexible bags 511 is shunk, then makes strut 4 push valve core rod 502 up, thus open the sealing between lower valve base 510 and bottom spool 509, be sealed and matched until valve core rod 502 drives upper valve core 505 and upper valve base 504 to be formed.Thus the microsample valve in this example has more purposes, such as may be used for needing according to continuing change to flexible bags 511 and constantly alternatively applying the occasion that pressure carrys out liquid make-up, slow release treatment such as in motion, once the stopping or excessive of this external pressure, valve is cut off.
Be normally closed structure by lower valve base 510, normally closed structure thus, the pressure of spring make between lower valve base 510 and bottom spool 509 for being sealed and matched, can be used in the application of pressure-bearing, such as external be positioned at high-order, for storing the container of liquid.
In this example, additionally use the design that lower valve base 510 internal diameter is greater than upper valve base 504 internal diameter, the benefit of this design is to back down bottom spool 509 easily to be applied to some special occasions, and due to upper valve base 504 internal diameter less, control the flow of liquid, to realize trace circulation.Guide holder 503 can make the operation of valve core rod 502 more smooth-going.
