[specific embodiment]
The invention will be further described below in conjunction with the accompanying drawings, and the structure and principle of this device are for the people of this profession
It is very clearly.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this
Invention.
The common C-shaped ring overall schematic of nuclear power evaporator and schematic cross-section are as shown in Figure 1 and Figure 2.The sealing dress of the present invention
It puts and is made 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-ring seal 3 with 2 joint face of valve block assembly, can prevent radiation water from being revealed at connection surface, as shown in Figure 3, Figure 4.
As shown in Fig. 5~Fig. 7,1 material of sealed briquette is natural rubber, has good anti-nuclear radiation effect.Sealing pressure
1 end shape of block can be fitted closely with C-shaped ring surface, and surrounding is sealed using special seal glue, ensures entire sealing device
Play excellent sealing effect.The first drainage channel 15 is provided with inside sealed briquette, cutter disengaging and C-shaped ring kernel during for punching
Radiate water discharge.
As shown in Fig. 8~Figure 10, valve block assembly is by uuper valve block 4, lower valve block 5, the first electrical ball valve 6, the second electrical ball valve
7th, multiple tracks O-ring seal 8, perforated channels 11 and input/output pipeline 13 form.Perforated channels are pressed with sealing in valve block assembly 2
The first drainage channel arrangement on the same axis, goes out for the disengaging of drill process drilling rod and radial contraction flow in block.Valve block assembly 1
Upper and lower valve block is connected combined integrated by bolt 9.Two valve block junctions are disposed with rubber gasket 10, and radial contraction flow is avoided to go out.Under
Radiation 12 and second drainage channel 14 of water collecting groove is disposed in valve block 5, radiation water collecting groove can avoid drill bit in punching from exiting
Process radiation water is flowed out from the perforated channels of rear portion.Radiation water collecting groove is connect with the second drainage channel, collected radiation water
Special retracting device can be drained to by the drainage channel.In drainage process is punched, electrical ball valve is remote controlled, passes through control
The keying sequence of two electrical ball valves is made, radiation water can be drained to special retracting device.
In drainage process, after drill bit exits the first electrical ball valve 6, the second electrical ball valve of remote control 6 makes its closure, so
Drill bit further exits electrical ball valve 7 afterwards, at this time can remote control electrical ball valve 7 make its closure, the punching of valve block assembly 2 at this time is logical
Road is in partition state.Controllable first electric-controlled ball valve 6 turns at this time, under this state perforated channels and radiation water collecting groove
It communicates, nuclear radiation water can be recycled to after perforated channels flow to radiation water collecting groove through the second drainage channel special inside C-shaped ring
In retracting device.
Compared with conventional hermetic measure, this sealing device be provided with it is multi-layer sealed, can according to C-shaped ring concrete shape design it is close
Seal platen shape, it is ensured that excellent sealing effect.This sealing device can realize remote control, and controllability is strong, avoid artificial
Scene participates in, and can prevent the radiation hazradial bundle that the leakage of nuclear radiation water generates in evaporator C-shaped ring.
