Compared with the prior art, beneficial effects of the present invention are as follows：
The present invention is by smooth cap head bonnet, piston-like piston core body, cylindrical seal body, round gasket and shelves
The overall decision design combination of ring, wherein the new composite air bleeding valve of manufacture, bonnet top are that smooth cap head can ensure that Filling gun
Head insertion is convenient；Groove and wedge-type seal area in the middle of bonnet may insure that air bleeding valve integral installation is sealed on shape
Property is good, is tightly combined；The round gasket and shelves ring of piston core body bottom are hollow cylindrical, it can be ensured that perfusion pipette tips are held
Air bleeding valve is easily passed through, is scrapped while two layers of composite seal device ensure that bottom is not easily damaged；The top of piston core body is band
Having around bundle of circles round estrade, round estrade around cylindrical seal body, band bundle of circles round estrade has small de-air hole, and small de-air hole is located at circle
Grid cloth is adhered to below band bundle of circles round estrade in stage body edge, piston core body, piston core body bottom is provided with round gasket, this
Planting design makes piston core body not vacillated now to the left, now to the right with bonnet, while when piston core body top stress, power can pass through piston core body
Round estrade and round gasket are transmitted to, the cylindrical seal body and round gasket that rubber is made can produce elasticity and allow power, reduction
Power extends whole service life, good airproof performance to the overall damage of piston core body.Good airproof performance of the present invention, it is safe and reliable, use
Long lifespan, suitable mass is promoted the use of.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of invention protection.
With reference to embodiment and embodiment, the present invention is further detailed explanation.
A kind of new composite air bleeding valve, it is characterized in that including bonnet 1, piston core body 2 and shelves ring 3, the bonnet 1 is generally
There is hollow accessory clamp area cylinder, inside, and the top of bonnet 1 is smooth cap head 101, and middle fluted 102 bottom is close for wedge shape
Area 103 is sealed, the top of piston core body 2 is to have cylindrical seal body 4, piston around band bundle of circles round estrade 201, round estrade 201
The bottom of core body 2 is provided with round gasket 5, and the shelves ring 3 is hollow cylindrical, and the top radius of circle of shelves ring 3 is more than bottom circle half
Footpath, the band bundle of circles round estrade 201 on the top of piston core body 2 is integrally through the inner hollow accessory clamp area of bonnet 1, and shelves ring 3 is pacified
Below the internal piston core body 2 of bonnet 1.
During hollow accessory clamp area monnolithic case inside the bonnet 1 is class truncated cone-shaped hole, hollow accessory clamp area
Heart line overlaps with the center line of band bundle of circles round estrade 201 above piston core body 2.
There is small de-air hole in the piston core body 2 around band bundle of circles round estrade 201, small de-air hole is located at the side of round estrade 201
Edge, when piston core body 2 is in 1 bottom position of bonnet, air is discharged from small de-air hole into bonnet bore, and bonnet bore is bonnet 1
Above internal hollow accessory clamp area and piston core body 2 with the gap between bundle of circles round estrade 201.
Adhere to the grid cloth that one layer of grid aperture is less than 100 mesh in the piston core body 2 below with bundle of circles round estrade 201.
The plastics that the bonnet 1 has rubber or shore hardness to be not more than 60 ° are made, shelves ring 3, cylindrical seal body 4 and close
Packing 5 has rubber to be made, and piston core body 2 has rubber or shore hardness to be made up of 54 °~57 ° of plastics.
Band bundle of circles round estrade 201 when actual use above piston core body 2 passes through the inner hollow accessory clamp area of bonnet 1,
So that piston core body 2 will not vacillate now to the left, now to the right；There is small de-air hole around band bundle of circles round estrade 201 in piston core body 2, when piston core body
2 be in 1 bottom position of bonnet when, air from small de-air hole enter bonnet bore discharge (piston core body and the hollow of bonnet interior are matched somebody with somebody
Part clamp has gap between area)；The motion upwards of piston core body 2 can be withstood when foaming agent is filled, until band circle in piston core body 2
Round estrade 201 is closed bonnet bore.Because the small de-air hole on piston core body 2 is located at the edge of round estrade 201, intermediate solid
Position can just block bonnet bore, so that bonnet 1 be blocked, foaming agent can not emerge；Band bundle of circles round estrade in piston core body 2
201 adhere to the grid cloth that one layer of grid aperture is less than 100 mesh below, can not can only be sent out by air by sticky foaming agent
Infusion can by the jack-up of piston core body 2 come because foaming agent although it is sticky under a certain pressure, can by screen cloth, so
The jack-up of piston core body 2 must be come, small de-air hole is blocked completely.
Above-described is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
