Abstract
A metal graphite O-shape ring comprises a metal ring, an upper graphite ring and a lower graphite ring. A circle of the upper surface of the metal ring is provided with an upper groove. The upper graphite ring is inlaid in the upper groove. A circle of the lower surface of the metal ring is provided with a lower groove, and the lower graphite ring is inlaid in the lower groove. The invention provides the metal graphite O-shape ring having advantages of reducing processing difficulty, simplifying processing technology and reducing cost.
Description
Technical field
The present invention relates to the sealing ring field, especially a kind of O type ring.
Background technology
The nuclear power station nuclear reactor pressure container is the closed container that is placed in nuclear reactor and bears huge operating pressure, is also referred to as reactor vessel, is the core in the pressurized-water reactor nuclear power plant, mainly is made up of top cover flange and container.Be in HTHP alternation state during the normal reactor operation, and the pressure vessel diameter is mostly more than 4 meters, owing to must seal fully between run duration top cover flange and the container, do not have any leakage, its sealing station is special.Domestic main employing metal O type ring seals at present, and this kind sealing ring is made up of spring, nickel-base alloy clad can and sealing silver layer three parts, and its difficulty of processing is big, complex process.Domestic reactor pressure vessel sealing ring mainly adopts import parts, costs an arm and a leg, and cost is high.
Summary of the invention
, complex process big for the difficulty of processing that overcomes existing sealing for pressure vessels ring, the deficiency that cost is high, the present invention provides a kind of metallic graphite carbon O type ring that reduces difficulty of processing, simplified processing process, reduces cost.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of metallic graphite carbon O type ring comprises becket, goes up graphite annulus and following graphite annulus, and upper surface one circle of said becket has groove, and the said graphite annulus of going up is embedded in said going up in the groove; Lower surface one circle of said becket has lower groove, and said graphite annulus down is embedded in the said lower groove.
Further, the said last exposed face of going up graphite annulus is circular-arc, and the following exposed face city of said graphite annulus down is circular-arc.
Beneficial effect of the present invention mainly shows: reduce difficulty of processing, simplified processing process, reduce cost.
Description of drawings
Fig. 1 is the structural representation of metallic graphite carbon O type ring.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1, a kind of metallic graphite carbon O type ring comprises becket 2, goes up graphite annulus 1 and following graphite annulus 3, and upper surface one circle of said becket 2 has groove, and the said graphite annulus 1 of going up is embedded in said going up in the groove; Lower surface one circle of said becket has lower groove, and said graphite annulus down inlays 3 in said lower groove.
Further, the said last exposed face of going up graphite annulus 1 is circular-arc, and the following exposed face city of said graphite annulus 3 down is circular-arc.
Present embodiment will be gone up the both sides up and down that graphite annulus 1 and following graphite annulus 3 are compressed on becket 2 respectively when installing, constitute metallic graphite carbon O type ring, by after with metallic graphite carbon O type ring be installed in can realize sealing on the flange face that will seal.
Adopt the soft graphite sealing ring to replace O type ring sealing surface, adopt becket to replace O type ring skeleton, the soft graphite sealing ring is embedded in the becket institute open channels; Soft graphite seal ring seal face adopts circular-arc, seals, and sealing ring and becket are connected as a single entity like this; When mounted; Equally metallic graphite carbon O type ring is placed on the flange face that will seal and get final product as placing O type ring, owing to the good performance of soft graphite, this kind hermetically-sealed construction compactness; Safe and reliable, and reduce expense greatly.
Claims (2)
1. metallic graphite carbon O type ring is characterized in that: said metallic graphite carbon O type ring comprises becket, goes up graphite annulus and following graphite annulus, and upper surface one circle of said becket has groove, said on graphite annulus be embedded in said in the groove; Lower surface one circle of said becket has lower groove, and said graphite annulus down is embedded in the said lower groove.
2. metallic graphite carbon O type ring as claimed in claim 1 is characterized in that: the said last exposed face of going up graphite annulus is circular-arc, and the following exposed face city of said graphite annulus down is circular-arc.
