Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
A kind of filling syringe needle for preventing water clock, including upper valve body 1, middle valve body 5, lower valve body 6, bonnet 2, needle tubing 8, pneumatic needle
First 7, concave end on the middle valve body 5, lower end protrusion, and the high spot of 5 lower end of middle valve body and the recess of upper end are all provided with
There are internal thread and sealing ring, the internal thread that the middle 5 upper end recess of valve body is equipped with and the external screw thread of the lower end of the upper valve body 1
Connection, the internal thread that the high spot of middle 5 lower end of valve body is equipped with respectively with the external screw thread of 8 upper end of needle tubing and the lower valve
6 upper end of body external screw thread connection, and between the high spot of 5 lower end of middle valve body and the lower valve body, middle 5 lower end of valve body
High spot and the needle tubing 8 between be equipped with sealing ring, connect upper valve body 1 and middle valve body 5 by the threaded upper ends of middle valve body 5
Lower end be threadedly coupled lower valve body 6, this structure of needle tubing 8 respectively, it can be achieved that three sections of present apparatus buttons tear formula open, solve replacements
The problem of material residual contamination occurred when kind or replacement batch or cross contamination, and the sealing that link position is equipped in the structure
