Description
Technical field
The invention belongs to technical field of nuclear power, and in particular to a kind of nuclear power station metallic graphite carbon sealing ring provision for disengagement.
Background technology
Metallic graphite carbon sealing ring is the conventional seal form of nuclear power station, is usually used in high pressure static seal environment, within
Outer ring metal is spacing, by graphite circle crimp, filling to sealing position, realizes sealing effectiveness.
Such as main faying face sealing of field gulf nuclear power plant reactor cooling medium pump is realized right using twice metallic graphite carbon sealing ring
The primary Ioops pressure seal of 15.6MPa.
, it is necessary to open sealing surface in turnover job, now sealing ring failure, it is not reproducible utilize, it is necessary to
Dismantle and change Xinmi City's seal.Due to long-term high-pressure extrusion, sealing ring and seal groove are combined relatively tightly, are difficult
Dismounting, and graphite circle cracky produces chip.Traditional dismounting mode chosen using sharp object, prize or with top
Silk ejects sealing ring, easily produces foreign matter, damage primary sealing area to cause the leakage of primary Ioops medium, Ren Yuanji
Tool injures equivalent risk, while also making dismounting man-hour long, there is influence originally nervous overhaul duration and increase
The problem of personnel's irradiation dose.
The content of the invention
It is an object of the invention to provide a kind of nuclear power station metallic graphite carbon sealing ring provision for disengagement, the provision for disengagement
It is simple and reliable for structure, being capable of dismounting quick to different size of sealing ring, complete, safety, solution engineering
In problem not easy to remove.
Realize the technical scheme of the object of the invention：A kind of nuclear power station metallic graphite carbon sealing ring provision for disengagement, the dress
Put including the door type frame on sealing cell body, the shadoof bolt being inserted in door type frame and be enclosed within shadoof spiral shell
Nut outside bolt, nut is located at the top of door type frame, is inserted at the top of shadoof bolt in door type frame top, carries
The bottom of bar bolt is located at the outer metal frame top of the sealing ring being arranged in the annular groove of sealing cell body.
The opening of described door type frame is towards sealing cell body, and door type frame is across the annular groove two in sealing cell body
Side.
Described door type frame is welded into a font by three blocks of steel plates.
The top steel plate of described door type frame is provided with a hole, and shadoof bolt is inserted in the hole.
Advantageous Effects of the invention：Metallic graphite carbon sealing ring provision for disengagement of the invention, simple structure,
Quick, complete, safe dismounting can be carried out to the metallic graphite carbon sealing ring of different-diameter size, effectively reduced
Working time and personal radiation dose, it is to avoid produce foreign matter and main faying face damage risk.
