Hole, liquid through-hole one end open is hollow with valve element top to be connected, and one end open is on the wall of valve element side；Valve element bottom sidewall has projection
Shoulder, there is a projection uuper valve chamber of corresponding valve body and lower valve chamber junction, projection abut with the shoulder of valve element it is spacing, it is convex
There is sealing ring at rising；
The lower surface of valve element bottom is connected with elastomeric element, and elastomeric element lower end is valve seat, and valve seat is arranged on drug discharging tube；
Ball is installed, ball is contacted with the inwall of valve body uuper valve chamber on the side wall at the top of described valve element；Under described ball
There is a thickened sealing ring side, and described thickened sealing ring is arranged on the side wall at the top of valve element, for sealed valve core top sidewall and
Space between the inwall of valve body uuper valve chamber.
It is preferably designed as, the lower end that there is annular groove, elastomeric element described valve seat upper surface is located in annular groove.
The present invention provide it is threadless exempt from pin dosing connector, during assembling, it is only necessary to by valve element and elastomeric element from going out
Pencil is inserted, and assembling is completed by upper valve base is then installed again.Ball, liquid through-hole, lower valve chamber of side wall at the top of valve element etc.
Structure, and the structure of elastomeric element connection valve element and valve seat, increased fluid passage, reduce and push away medicine resistance.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The specific embodiment of the present invention is described with reference to the drawings, as shown in figure 1, threadless exempt from pin dosing connector, bag
Include and uuper valve chamber and lower valve chamber are provided with valve body 2, valve body 2, the top of valve body 2 is dosing mouth, there is lid 1, the lower valve of valve body 2 outside dosing mouth
Chamber is connected with drug discharging tube 3, and the two ends of drug discharging tube 3 are medicine outlet；
Valve element 4 is provided with uuper valve chamber, the described top of valve element 4 extend into dosing mouth, and the top of valve element 4 is hollow, and there is medicine hollow lower section
Fluid through-hole 5, the one end open of liquid through-hole 5 is hollow with the top of valve element 4 to be connected, and one end open is on the side wall of valve element 4；The bottom of valve element 4
Side wall has the shoulder 6 of projection, and there are projection, the raised shoulder 6 with valve element 4 in the uuper valve chamber of corresponding valve body 2 and lower valve chamber junction
Abut spacing, high spot has sealing ring 10；
The lower surface of the bottom of valve element 4 is connected with elastomeric element 7, and the lower end of elastomeric element 7 is valve seat 8, and valve seat 8 is arranged on drug discharging tube 3
On；
Ball 11 is installed on the side wall at the described top of valve element 4, ball 11 is contacted with the inwall of the uuper valve chamber of valve body 2；Described
There is thickened sealing ring 12 lower section of ball 11, and described thickened sealing ring 12 is arranged on the side wall at the top of valve element 4, for sealing valve
