Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the utility model. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1, the float valve rod sealing ring structure comprises a valve rod 1, a valve clack 2, an O-shaped sealing ring 3, a valve clack sealing ring 4, a valve clack sealing ring pressing sheet 5 and a valve seat 6, wherein the valve rod 1 sequentially penetrates through the valve clack 2, the O-shaped sealing ring 3, the valve clack sealing ring 4, the valve clack sealing ring pressing sheet 5 and the valve seat 6, the valve clack sealing ring 4 is sleeved on the valve rod 1 through the O-shaped sealing ring 3, the valve clack 2 is attached to the upper part of the valve clack sealing ring 4, the valve clack sealing ring pressing sheet 5 is attached to the lower part of the valve clack sealing ring 4, the edge part of the valve clack sealing ring 4 is attached to the valve seat 6, the valve seat 6 is hollow, the nut 7 is sleeved on the valve rod 1 in the valve seat 6 through threads, and an annular bulge a4.1 and an annular bulge B4.2 are arranged on the valve clack sealing ring 4, the annular protrusions A4.1 are located on the upper end face and the lower end face of the valve clack sealing ring 4, and the annular protrusions B4.2 are located at the joint of the valve clack sealing ring 4 and the O-shaped sealing ring 3.
