Abstract
The utility model discloses a metal sealing ring with corner protection, which comprises a metal ring body. Rigid corner wrap with material strength high than that of metal is arranged at the corner portion of the metal ring body, the rigid corner wrap is embedded into the metal ring body and tightly attached to the metal ring body to form a whole metal sealing ring. Cellosilk distributed evenly in a net shape is arranged in the metal ring body. The metal sealing ring with the corner protection effectively protects a corner of the metal ring body, not only protects a corner position with weakest strength and avoids sealing invalidation due to the fact that the corner portion is damaged in the prior art, but also greatly improves integral pressure resistant capacity of the metal ring body, thereby improving reliability of safety and sealing performance of a device, being particularly suitable for high-pressure fluid dynamic and static sealing occasions of severe working conditions and capable of being widely applied to pipeline flange sealing, stuffing box sealing and the like which are involved in conveying process of various high-pressure fluids.
Description
Technical field
The utility model relates to the high-temperature, high pressure fluid field of sealing technology, relates in particular to a kind of flexible metal seal ring with corner protection.
Background technique
In the industrial processes, valve is widely used in the various pipe-line systems, and the sealing problem of high-temperature high pressure valve wherein; Cause people's attention and attention gradually; In a single day the external leaks accident takes place in its medium, except that causing bigger economic loss, also possibly seriously injure personal safety.The flexible metal seal ring is used in the sealing of High temperature valve generally; That the sectional shape of common metal seal ring has is square, trapezoidal, parallelogram, V-type, M type etc.; The material of metallic packing ring has in single flexible metal, metal and metal composite and the metal resin filling etc., in often only being applicable to, the sealing of low flow medium.When being used for high-temperature high pressure valve; Because the corner of metallic packing ring is the weakest position; In case receive the effect of high-pressure medium, will at first destroy, and progressively accumulation is expanded and is caused and further destroy; Cause the sealing reliability and the Security of high pressure valve not high, the metallic packing ring life-span is short.
The model utility content
Goal of the invention: in order to overcome the deficiency that exists in the existing technology, the utility model provides a kind of metallic packing ring with corner protection, makes metallic packing ring be adapted to the use in high temperature and high pressure environment.
Technological scheme: for solving the problems of the technologies described above, the technological scheme of the utility model sampling is:
A kind of metallic packing ring with corner protection; Comprise the metal ring body; Corner portion at the metal ring body is provided with the rigidity cornerite that the strength of materials is higher than metal; Said rigidity cornerite is pressed and is embedded in the metal ring body, and fits tightly formation metallic packing ring integral body with the metal ring body, in the metal ring body, is provided with to be netted equally distributed cellosilk.
Said rigidity cornerite is prefabricated profiled toroidal shell, can be metal material or non-metallic material.
Beneficial effect: the metallic packing ring that the utility model provides with corner protection; The corner that has effectively comprised the metal ring body; Not only protected the weakest angle position of intensity; Avoid causing from the corner destroying and the generation seal failure in the past, also improved the entire compression ability of metal ring body greatly, make the Security of equipment, the reliability of sealing be improved; Be specially adapted to the dynamic and static sealing occasion of the abominable high-pressure liquid of operating mode, can be widely used in piping flange sealing related in all kinds of high-pressure liquid course of conveying, packing box seal etc.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Be depicted as a kind of metallic packing ring like accompanying drawing 1 with corner protection; The sealing ring comprises metal ring body 1; Corner portion at metal ring body 1 is provided with the rigidity cornerite 2 that the strength of materials is higher than metal; Said rigidity cornerite 2 is pressed and is embedded in the metal ring body 1, and fits tightly formation metallic packing ring integral body with metal ring body 1, in metal ring body 1, is provided with to be netted equally distributed cellosilk.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
