Abstract
The utility model discloses a sealing device characterized by corrosion resistance, high temperature resistance and high pressure resistance, and aims to solve the problem that the sealing performance is poor in the prior art. The sealing device at least includes a sealing column with a columnar sealing surface and a sealing cylinder with a cylindrical sealing surface, wherein the cylindrical sealing surface of the sealing cylinder and the columnar sealing surface of the sealing column are matched with each other; the sealing column is mounted behind the sealing cylinder, a sealing cavity is formed between the front end of the sealing column and the inside of the sealing cylinder, and at least one rubber sealing piece and a metal sealing piece are arranged on the sealing column, and are arranged at interval axially. Through the adoption of the sealing device having the structure, the cylindrical sealing surface tightly presses the outer sides of the metal sealing piece, the rubber sealing piece and a retainer ring with certain pressure; the columnar sealing surface tightly presses the inner sides of the metal sealing piece, the rubber sealing piece and a retainer ring with certain pressure; therefore, the cylinder and column sealing is realized under the conditions of corrosion medium, high temperature and high pressure.
Description
Technical field
The utility model relates to a kind of corrosion-resistant and high-temperature resistant high pressure seal, is applicable to the sealing of cylindrical shape sealing surface and cylindrical seal face, is specially adapted to the sealing of cylinder and cylinder under Korrosionsmediums such as hydrogen sulfide and the high-temperature and high-pressure conditions.
Background technique
Existing corrosion-resistant and high-temperature resistant high pressure seal is a kind of to be to adopt the metal seal sealing, and another kind is to adopt rubber seal, retaining ring sealing.The problem of first kind of structure existence is that high pressure sealing performance is unreliable.The problem of second kind of structure existence is rubber seal, the back-up ring that can not avoid in the aggressive medium corrosion seal arrangement.
The model utility content
For overcoming above-mentioned defective, the purpose of this utility model provides a kind of corrosion-resistant and high-temperature resistant high pressure seal simple in structure, easy to use.
For achieving the above object, the utility model corrosion-resistant and high-temperature resistant high pressure seal, at least comprise sealing column with cylindrical seal face and the sealing drum with cylindrical shape sealing surface, the cylindrical shape sealing surface of described sealing drum and the cylindrical seal face of sealing column are suitable; After described sealing column is installed in sealing drum, in sealing column front end and the inner airtight chamber that forms of sealing drum, be provided with a rubber seal and a metal seal at least on described sealing column, described rubber seal and metal seal axially spaced-apart are provided with.
Wherein, axially be provided with the twice groove at least, in described groove, be respectively equipped with rubber seal at described sealing column leading portion.
Wherein, also be provided with a Sealing shield ring in described groove, described Sealing shield ring is arranged on nearly sealing drum one side.
Wherein, the cylindrical shape sealing surface of described sealing drum is inside and outside two sections, and the diameter of outer cylindrical section shape sealing surface forms step greater than the diameter of inner segment cylindrical shape sealing surface between inside and outside two sections; Cylindrical section shape sealing surface is provided with annular boss outside the segment trailer correspondence before described sealing column; Described metal seal is arranged between annular boss and the step.
Adopt the seal arrangement of said structure, the cylindrical shape sealing surface compresses the outside of metal seal, rubber seal, back-up ring with certain pressure, the cylindrical seal face compresses the then interior of metal seal, rubber seal, back-up ring with certain pressure, realizes the sealing of cylinder and cylinder under aggressive medium, high-temperature and high-pressure conditions.The overall structure novelty, metal seal, rubber seal, back-up ring surface are not perishable, can use under high-temperature and high-pressure conditions, and be safe and reliable, long service life.
Description of drawings
Fig. 1 is the example structure schematic representation of the utility model corrosion-resistant and high-temperature resistant high pressure seal.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Diagram has been described an embodiment of the present utility model.
As shown in Figure 1, the utility model corrosion-resistant and high-temperature resistant high pressure seal, at least comprise sealing column 1 with cylindrical seal face and the sealing drum 2 with cylindrical shape sealing surface, the cylindrical shape sealing surface of described sealing drum and the cylindrical seal face of sealing column are suitable; After described sealing column is installed in sealing drum, in sealing column front end and the inner airtight chamber 8 that forms of sealing drum, on described sealing column, be provided with a rubber seal 6 and a metal seal 3 at least, described rubber seal and metal seal 3 axially spaced-apart settings.
As further improvement of the present utility model, axially be provided with the twice groove at least at described sealing column leading portion, in described groove, be respectively equipped with rubber seal 4,6.In order further to increase sealing effect, in described groove, also be provided with a Sealing shield ring 5,7, described Sealing shield ring is arranged on the front side of rubber seal, promptly near sealing drum one side.
Wherein, the cylindrical shape sealing surface of described sealing drum is inside and outside two sections, and the diameter of outer cylindrical section shape sealing surface forms step greater than the diameter of inner segment cylindrical shape sealing surface between inside and outside two sections; Cylindrical section shape sealing surface is provided with annular boss outside the segment trailer correspondence before described sealing column; Described metal seal 3 is arranged between annular boss and the step.
In summary, seal arrangement of the present utility model has carried out organic combination with metal seal and rubber seal, can realize the sealing of cylinder and cylinder under aggressive medium, high-temperature and high-pressure conditions.The overall structure novelty, metal seal, rubber seal, back-up ring surface are not perishable, can use under high-temperature and high-pressure conditions, and be safe and reliable, long service life.
Below only be the specific descriptions that given with reference to the accompanying drawings embodiment makes; but this embodiment does not limit the application's protection domain; for a person skilled in the art, the modification of being made on content basis disclosed in the utility model can not break away from spirit of the present utility model and category.
