Abstract
The utility model provides a sealing structure, and aims to solve the problems of the conventional sealing structure that sealant is used during installation, and the surface of a sealing ring is easily bumped during transportation and conveying processes. The sealing structure provided by the utility model comprises two opposite sealing surfaces; a sealing groove is formed on one sealing surface; an O-shaped ring is arranged in the sealing groove which is a special U-shaped groove; the cross section of the section of the special U-shaped groove near the bottom of the special U-shaped groove is matched with O-shaped ring in shape; the open section of the special U-shaped groove is wider than the section near the bottom of the special U-shaped groove; a step is formed on an end surface opposite to the sealing groove; and because of the step, the sealing surface is lower than the other part on the end surface. The sealing structure with reliable sealing effect and convenient assembly is used in high-pressure sulfur hexafluoride gas insulated metal-enclosed switchgears, and can effectively prevent sulfur hexafluoride gas from leaking.
Description
Technical field
The utility model relates to a kind of sealing configuration, relates in particular to a kind of sealing configuration that the high pressure sulfur hexafluoride Cubicle Gas-Insulated Switchgear seals sulfur hexafluoride gas that is used for.
Background technique
The high pressure sulfur hexafluoride Cubicle Gas-Insulated Switchgear is called for short GIS, sealing configuration all is to adopt the structure of placing plane sealing ring or O type circle in the rectangular seal groove among the high pressure GIS at present, as shown in Figure 1, in the sealing structure, the degree of depth of sealed groove is less than the diameter of O type circle, so that O type circle can be expressed to by relative sealing surface, thereby performance seal action, the width of sealed groove is slightly larger than the diameter of O type circle, so that O type circle can place groove, and is out of shape to both sides when being extruded.This sealing configuration need use sealer that O type circle is bonded in the sealed groove with Drop-proof when mounted, and the sealing anchor ring easily damages in transportation, handling process, thereby causes that sulfur hexafluoride gas leaks.
The model utility content
The technical problems to be solved in the utility model is, at the shortcoming that exists in the above prior art, proposes a kind of simple in structure, sealing configuration of being beneficial to assembling.
For solving above technical problem, a kind of sealing configuration provided by the utility model, comprise two relative sealing surfaces, one of them sealing surface is provided with sealed groove, be provided with O type circle in the sealed groove, described sealed groove is special-shaped U-groove bevel, and the cross section that the close bottom land of special-shaped U-groove bevel is a section and the shape of O type circle are suitable, and the width of open section is greater than the width near the bottom land section.
With respect to prior art, the utility model has been obtained following beneficial effect: the cross section that the close bottom land of special-shaped U-groove bevel is a section and the shape of O type circle are suitable, can play the effect that clamps O type circle, thereby can be in order to avoid use sealer.
As improvement of the present utility model, be provided with step with the sealed groove opposing end faces, step makes sealing surface be lower than other position on this end face.Sealing surface is lower than other position on the end face, can avoid transportation, move and installation process in the sealing surface of damaging, leak thereby cause GIS that sulfur hexafluoride gas takes place.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the schematic representation of existing sealing configuration.
Fig. 2 is the schematic representation of the utility model sealing configuration.
Fig. 3 is the enlarged view of sealed groove in the utility model.
Fig. 4 is the enlarged view of sealing surface in the utility model.
Among the figure: 1 sealing surface, 1a step, 2 sealed grooves, 3O type circle, 4 bolts.
Embodiment
As shown in Figure 1, sealing configuration of the present utility model comprises two relative sealing surfaces, and one of them sealing surface is provided with sealed groove 2, is provided with O type circle 3 in the sealed groove 2, bolt 4 is pressed on O type circle 3 between sealed groove 2 and the sealing surface 1 after two sealing surfaces are connected.
As shown in Figure 2, sealed groove 2 is special-shaped U-groove bevel, and the cross section that the close bottom land of special-shaped U-groove bevel is a section and the shape of O type circle are suitable, so that clamping O type circle; The width of open section is greater than the width near the bottom land section, so that the space of O type circle 3 distortion to be provided.
As shown in Figure 3, be provided with step 1a with the sealed groove opposing end faces, step 1a makes sealing surface 1 be lower than other position on this end face, with avoid transportation, move and installation process in the sealing surface of damaging.
During use, charge into the sulfur hexafluoride gas of certain pressure in GIS, sealing surface 1, sealed groove 2 and O type circle 3 cooperate, and the pressure of bolt makes O type circle 3 produce plastic deformation, plays seal action.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all fall into the protection domain of the utility model requirement.
Claims (2)
1. sealing configuration, comprise two relative sealing surfaces, one of them sealing surface is provided with sealed groove, be provided with O type circle in the sealed groove, it is characterized in that, described sealed groove is special-shaped U-groove bevel, and the cross section that the close bottom land of special-shaped U-groove bevel is a section and the shape of O type circle are suitable, and the width of open section is greater than the width near the bottom land section.
2. a kind of sealing configuration according to claim 1 is characterized in that, is provided with step with the sealed groove opposing end faces, and step makes sealing surface be lower than other position on this end face.
