Portion is provided with bulge loop, and valve rod lower end is positioned through the stairstepping via of valve plate by the bulge loop clamping, and valve rod lower end passes through valve
Cover and be connected with through hole after plate；The outer wall of valve plate is resisted against in the upper end of bonnet on seamed edge edge；The upper end of spring is sleeved on axle
Part of the set below the shaft shoulder, the lower end of spring is sleeved on the bulge loop at the middle part of valve rod.
Further, the outer wall of the flanged lip and the rectangular arrangement of bonnet outer wall, valve body lower end inwall and bonnet
On be provided with mutually corresponding to be used to be fitted together to the cell body of sealing ring, is embedded with O-ring seals in the cell body；On valve body lower end face
Groove type structure is provided with, between valve body lower end face and the flanged lip of bonnet, the sealing of O shapes is equiped with groove type structure
Circle.
Further, seamed edge edge is arranged to chamfering structure in the bonnet upper end.
Further, sealing rubber layer is arranged with outside the valve plate, seamed edge edge in the upper end of the sealing rubber layer and bonnet
It is tightly connected.
Further, the middle part of the upper surface of the valve plate is bulge-structure, and the bulge-structure is provided with a circle
Inner groovy.
Further, the globoidal structure of the lower surface of the valve plate generally evagination, it is easy to sealing to coordinate.
Its advantage is the present invention compared with prior art：The valve body structure of the present invention is simple, special by valve plate
Structure has reached the double effectses of feed liquor and only liquid, while under the guiding of valve rod and the cooperation of spring, makes the non-return of the present invention
Valve can instant return.Meanwhile the present invention is contacted between valve plate and bonnet using sealing rubber layer using more firm face, makes this
The valve seal effect of invention is more preferable.
