[detailed description of the invention]
The invention will be further described below in conjunction with the accompanying drawings, and the structure of this device and principle are for the people of this specialty
It is the most clearly.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit this
Invention.
Nuclear power evaporator common C-shaped ring overall schematic and schematic cross-section are as shown in Figure 1 and Figure 2.The sealing dress of the present invention
Put and be made up of sealed briquette 1, valve block assembly 2.Sealed briquette 1 and valve block assembly 2 are integrally connected by bonding mode.Sealed briquette
1 arranges O RunddichtringO 3 with valve block assembly 2 joint face, can prevent radiating water and reveal at connection surface, as shown in Figure 3, Figure 4.
As shown in Fig. 5～Fig. 7, sealed briquette 1 material is natural rubber, has good anti-nuclear radiation effect.Seal pressure
Block 1 end shape can fit tightly with C-shaped ring surface, and surrounding uses special seal glue to seal, it is ensured that whole sealing device
Play excellent sealing effect.The first drainage channel 15 is had, cutter turnover and C-shaped ring kernel when being used for punching inside sealed briquette
Radiation water is discharged.
