Abstract
The utility model is a nuclear-grade metal graphite gasket which has the advantages of erosion resistance, irradiation resistance, large pressure bearing, wide temperature range, good temperature transient conditions and lower application cost. The utility model comprises an outer ring, an inner ring and a nuclear-grade graphite seal ring inlaid between the outer and the inner rings and is characterized in that the nuclear-grade graphite seal ring is a graphite ring.
Description
(1) technical field
The utility model relates to packing ring class technical field, is specially nuclear level metallic graphite carbon packing ring.
(2) background technique
The structure of existing nuclear level metallic graphite carbon packing ring is seen Fig. 1, it comprises outer shroud 1, interior ring 3 and is set in nuclear level carbon seal ring between outer shroud 1, the interior ring 3, and described seal ring is to be made of ring 4 in steel band outer shroud 5, the steel band and the graphite annulus 2 that is set between outer shroud, the interior ring.What this packing ring sealed in using is the carbon seal ring of nuclear level, and the thermal expansion coefficient of steel band 4,5 outside in the graphite and graphite 2 is inconsistent, and the pressure that can bear is little, and the instantaneous conditions of temperature is poor, influenced high sealing performance to a certain extent, the temperature range that can bear is narrow; The steel band in the outside has injury to follow-up flange connecting sheet in the graphite annulus, scratch easily, and flange plate price height, the frequent replacing causes user cost to improve, and the more change poles inconvenience of flange plate.
(3) summary of the invention
At the problems referred to above, the utility model provides another nuclear level metallic graphite carbon packing ring, its corrosion-resistant, anti-irradiation, and the pressure that can bear, temperature range are wide, and the temperature instantaneous conditions is good, and user cost is lower.
Its technological scheme is such: it comprises outer shroud, interior ring and be set in nuclear level carbon seal ring between outer shroud, the interior ring, it is characterized in that: the carbon seal ring of described nuclear level is a graphite annulus.
In the said structure of the present utility model, make seal ring with pure graphite annulus, graphite is corrosion-resistant, radioresistance is stronger, adopt single material graphite to make seal ring, has avoided the inconsistent and influence to strength, bearing temperature that produces of invar band and graphite thermal expansion coefficient in the prior art; And graphite has toughness, greasy property, can not produce injury to follow-up flange plate, and prolonged the working life of flange plate, and user cost reduces.
(4) description of drawings
The structural representation that Fig. 1 looks for existing nuclear level metallic graphite carbon packing ring master;
The structural representation that Fig. 2 looks for the utility model master.
(5) embodiment
See Fig. 2, the utility model comprises outer shroud 1, interior ring 3 and is set in nuclear level carbon seal ring 2 between outer shroud 1, the interior ring 3 that the carbon seal ring 2 of nuclear level is a graphite annulus.
Claims (1)
1. a nuclear level metallic graphite carbon packing ring, it comprises outer shroud, interior ring and is set in nuclear level carbon seal ring between outer shroud, the interior ring that it is characterized in that: grade carbon seal ring of described nuclear is a graphite annulus.
