Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a sealing performance adjustable carbon dioxide high pressure stop valve, includes valve body 1, valve gap 2, ends hole 5, valve clack 6, valve rod 7 and runner 8, and water inlet 3 and delivery port 4 have been seted up respectively to the both ends of valve body 1, still include:

the upper bottom plate 9 is positioned on the lower end surface of the valve rod 7;

the lower bottom plate 10 is positioned on the upper end surface of the valve clack 6;

and the damping mechanism is positioned between the upper bottom plate 9 and the lower bottom plate 10.
