Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, 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, belongs to the scope of the utility model protection.
Refer in Fig. 1-2, the utility model embodiment, a kind of plunger-type resorption glue dispensing valve, including cylinder head 1, cylinder
The inside of lid 1 is provided with cylinder seal circle 11 and spring 12, and cylinder seal circle 11 is played cylinder head 1 and the sealing of the interface of cylinder 2
The effect got up so that cylinder 2 does not have gas leakage operationally, the bottom of cylinder head 1 is connected with gas by screw thread
Cylinder 2, by then passing through the mode of screw thread flexible connection, facilitates the installation and removal of cylinder head 1 on the cylinder 2；It is provided with cylinder 2
Piston 3, the bottom of cylinder 2 is nested with valve body 21, and piston packing 31, piston packing 31 are provided with the side wall of piston 3
Play a part of sealing piston 3, when piston 3 is moved up and down, the inwall connection of sealing piston 3 and cylinder 2 so that gas will not
Discharge, cylinder head 1 is connected on piston 3 by spring 12, and piston 3 is moved up and down by spring 12；The bottom of piston 3 connects
Piston rod 32 is connected to, the top of piston rod 32 is buckled in the bottom of piston 3, and piston rod 32 follows moving up and down and moving for piston 3
It is dynamic, it is nested with the first sealing ring 4, the sealing ring 6 of valve cone 5 and second on piston rod 32, the first sealing ring 4 and the second sealing ring 6
Diameter is identical, and valve cone 5 is located between the first sealing ring 4 and the second sealing ring 6, and the first sealing ring 4 and the second sealing ring 6 are set respectively
In the both sides up and down of valve cone 5 so that piston rod 32 drives valve cone 5 to move, and the first sealing ring 4 and the second sealing ring 6 are close by valve cone 5
