[0031] like Figure 3-Figure 7 As shown, based on the above embodiment, in order to enable the eccentric hemispherical valve to achieve efficient sealing and durable functions, this embodiment provides the following design:

[0032] The eccentric hemispherical body 4 comprises a top column 41, an upper support plate 42, a sealing disc 43, a lower support plate 44, a bottom column 45, a sealing sleeve 46 and an assembly ring 47. The top column 41 is rotatably connected to the assembly cover 31. An upper support plate 42 is provided on the top of the top column 41. A sealing disc 43 is provided on the end of the upper support plate 42 away from the top column 41. A lower support plate 44 is provided on the top of the sealing disc 43.

The assembly ring 47 is threadedly connected to the sealing disc 43. The sealing sleeve 46 is engaged with the sealing disc 43. A sealing arc surface is formed on the edge of the sealing sleeve 46. Through the threaded connection between the assembly ring 47 and the sealing disc 43, the worn and aged sealing sleeve 46 can be conveniently replaced after the eccentric hemispherical body 4 is used for a long time.

[0033] In this embodiment, the sealing assembly 2 includes an assembly cylinder 21, a sealing cylinder 22 and a sealing annular plate 23. The assembly cylinder 21 is arranged inside one end of the valve body 1, and the assembly cylinder 21 is connected with the valve body 1 by snapping. A sealing cylinder 22 is provided in the middle of the inner side of the assembly cylinder 21, and a sealing annular plate 23 is provided at one end of the sealing cylinder 22 facing the inside of the valve body 1. An inclined sealing surface is provided at one end of the sealing annular plate 23 away from the sealing cylinder 22, and the inclined sealing surface fits and slides with the sealing arc surface; by fitting and sliding with the inclined sealing surface and the sealing arc surface, the eccentric hemispherical body 4 can fit tightly with the sealing assembly 2 when it is closed, thereby ensuring the sealing effect of the eccentric hemispherical body 4;

[0034] In this embodiment, the sealing cylinder 22 is threadedly connected to the assembly cylinder 21, the sealing annular plate 23 fits and slides with the assembly cylinder 21, and an adjustment seat 24 is provided on the inner side of the sealing cylinder 22, and a snap-fit ​​groove is provided in the middle of the adjustment seat 24; through the threaded connection between the sealing cylinder 22 and the assembly cylinder 21, after the sealing annular plate 23 is worn out after long-term use, the sealing cylinder 22 is rotated to change the distance between the sealing annular plate 23 and the eccentric hemispherical body 4, so that the fit tightness between the inclined sealing surface and the sealing arc surface can be adjusted, so that the problem of reduced sealing effect caused by aging of the sealing annular plate 23 and the sealing sleeve 46 can be solved to a certain extent, which is convenient for improving the service life of the eccentric hemispherical valve; the setting of the adjustment seat 24 allows the staff to engage with the snap-fit ​​groove in the middle of the adjustment seat 24 through a device such as a cross bar, so as to facilitate adjusting the position of the sealing cylinder 22;

By engaging the assembly columns 25 with the valve body 1, the position of the assembly cylinder 21 can be limited when the sealing cylinder 22 rotates.

[0036] The working principle and use process of this utility model:

[0037] When using:

[0038] First, the two ends of the eccentric hemispherical valve need to be connected to the pipeline. When the medium needs to flow, the actuator 5 controls the eccentric hemispherical body 4 to rotate, so that the eccentric hemispherical body 4 is separated from the sealing component 2. At this time, the medium in the pipeline will pass through the middle of the sealing component 2. When it is necessary to block the flow of the medium, the actuator 5 controls the eccentric hemispherical body 4 to contact and seal with the sealing component 2. At this time, the eccentric hemispherical body 4 can block the flowing medium;

[0039] During production and assembly:

[0040] When the eccentric hemispherical body 4 is produced and assembled, the eccentric hemispherical body 4 can be combined with the assembly cover 31 and the actuator 5 in the assembly component 3 in advance, and then the eccentric hemispherical body 4 is inserted into the valve body 1 through the assembly opening. When the eccentric hemispherical body 4 completely enters the valve body 1, the staff aligns and contacts the assembly cover 31 with the assembly top ring 11, and then rotates the sealing sleeve 32. The sealing sleeve 32 will be threadedly connected with the assembly top ring 11. At this time, the assembly disk will correct the position of the eccentric hemispherical body 4 so that the top of the eccentric hemispherical body 4 is assembled and engaged with the bottom inside the valve body 1. In this way, the production and assembly of the eccentric hemispherical valve is more convenient.
