Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of adhesive-spill-preventing valve pocket, including needle 1 and valve body 2, needle 1 are lived
Dynamic connection valve body 2, the through hole that needle 1 can be blocked at the center of valve body 2, the inner side of valve body 2 are logical provided with first through hole 21 and second
Hole 22, first through hole 21 connect the second through hole 22, and the side of first through hole 21 offers jet, jet-sub insertion jet
It is interior, and sizing material is sprayed, the central axis of the central axis of first through hole 21 and the second through hole 22 forms 90 degree of angles, logical second
The inner side in hole 22 is provided with filling pipe 3, valve pocket 4 and hold-down ring 5, the lateral wall connection valve body 2 of filling pipe 3, the inner side of filling pipe 3
Wall is flexibly connected needle 1, the top connection valve pocket 4 and hold-down ring 5 of filling pipe 3, the base connection hold-down ring 5 of valve pocket 4, valve pocket 4
It is connected with hold-down ring 5 with valve body 2, the junction of hold-down ring 5 and valve body 2 is provided with sealing ring, can be protected after installing sealing ring
