Abstract
The utility model discloses a seal ring for a vacuum pressurizing impregnation tank, which has good sealing effect. The seal ring comprises a seal ring body, wherein an inflation concave surface is formed at the lower end of the seal ring body, and a semi-circular bulge and an upwardly-tilted flange are formed on the two sides of the upper end of the seal ring body respectively. The utility model has the advantages that a sealing surface of a closure flange is pressed on the semi-circular bulge during vacuuming to form an O-shaped ring, thereby achieving small contact surface, good sealing effect and high vacuum degree; and as the semi-circular bulge on the outer side is in contact with the sealing surface of the closure flange during pressurization, the upwardly-tilted flange is also adhered to the sealing surface of the closure flange due to the internal pressure on the inner side of the seal ring, thereby achieving double sealing effects to maintain the pressure inside the tank and avoid leakage.
Description
Technical field
The utility model relates to a kind of vacuum pressed impregnating autoclave, relates in particular to a kind of seal ring that is used on the vacuum pressed impregnating autoclave.
Background technique
The vacuum pressed impregnating autoclave mainly is used in transformer, electrical machine insulation dipping lacquer place, makes fully impregnated insulating paint of transformer, motor surface, increases the service life.The structure of vacuum pressed impregnating autoclave mainly comprises: have the cover flange of profile of tooth, the clip that blocks cover flange, cylindrical shell and be arranged on the interior seal ring of clip bottom seal groove.The existing overall structure that is used in the seal ring on the vacuum pressed impregnating autoclave is a rectangular, be provided with an inflation concave surface in the bottom of seal ring, when the vacuum pressed impregnating autoclave is vacuumized, because (diameter is big more for the distortion of the sealing surface of cover flange, the distortion of sealing surface is big more), cause the sealing surface of cover flange not fit equably with the clip sealing surface, seal ring and cover flange surface of contact are big, cause the seal ring pressurized inhomogeneous, the part is free air infiltration to come, thereby does not reach the degree of vacuum that needs; When the vacuum pressed impregnating autoclave was pressurizeed, the part had air to overflow, and does not keep the pressure of setting, and does not so just reach the requirement of degree of vacuum and pressurization degree, and insulated paint can not be flooded effectively, makes transformer, motor not reach desirable dipping effect equally.
The model utility content
Technical problem to be solved in the utility model is: the seal ring on the vacuum pressed impregnating autoclave of being used in that a kind of good sealing effect is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: be used in the seal ring on the vacuum pressed impregnating autoclave, comprise: the seal ring body, be provided with the inflation concave surface in the lower end of seal ring body, the rib that on the both sides, upper end of described seal ring body, is respectively arranged with semicircle projection and is upturned.
The utility model has the advantages that: said structure be used in seal ring on the vacuum pressed impregnating autoclave, when vacuumizing, the sealing surface of cover flange is pressed on the semicircle projection, becomes " O " type circle, surface of contact is few, good sealing effect, degree of vacuum height; During pressurization, the semicircle projection that is arranged on the outside contacts with the sealing surface of cover flange, and is inboard because be subjected to interior pressure, the rib that is upturned also can be fitted with the sealing surface of cover flange, will form two seals like this, keep jar interior pressure constant, leakage phenomenon can not take place.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is used in the structural representation of the seal ring on the vacuum pressed impregnating autoclave for the utility model.
Fig. 2 is equipped with the structural representation that the utility model is used in the vacuum pressed impregnating autoclave of the seal ring on the vacuum pressed impregnating autoclave.
Fig. 3 is the structure for amplifying schematic representation of A part among Fig. 2.
Among the figure: 1, seal ring body, 2, the inflation concave surface, 3, semicircle projection, 4, rib, 5, clip, 6, seal groove, 7, tank body, 8, end socket, 9, cover flange.
Embodiment
As shown in Figure 1, be used in the seal ring on the vacuum pressed impregnating autoclave, comprise: seal ring body 1 is provided with inflation concave surface 2, the rib 4 that is respectively arranged with semicircle projection 3 and is upturned on the both sides, upper end of described seal ring body 1 in the lower end of seal ring body 1.
As Fig. 2, shown in Figure 3, the seal ring of said structure is contained in the seal groove that cooperatively interacts with it 6 on the clip 5 during use, clip 5 links together tank body 7 and end socket 8, in clip 5, be provided with cover flange 9, the rib 4 that is arranged on the semicircle projection 3 of seal ring upper end and is upturned offsets with the sealing surface of cover flange 9 respectively, when the vacuum pressed impregnating autoclave is vacuumized, the sealing surface of cover flange 9 is pressed on the semicircle projection 3, become " O " type circle, surface of contact is few, good sealing effect, the degree of vacuum height; When the vacuum pressed impregnating autoclave is pressurizeed, the semicircle projection 3 that is arranged on the outside contacts with the sealing surface of cover flange 9, inboard because be subjected to interior pressure, the rib 4 that is upturned also can be fitted with the sealing surface of cover flange 9, will form two seals like this, keep jar interior pressure constant, leakage phenomenon can not take place.
