Abstract
The utility model discloses a leaking stopping device for a sulfur hexafluoride gas delivery pipeline. the device comprises a jacketing, wherein the jacketing is in a structure of two pieces, and the two pieces of the jacketing are fixedly connected through connecting bolts, the jacketing includes a pipeline ring wall and a flange ring wall, the diameter of the flange ring wall is larger than that of the pipeline ring wall, besides, a circular ring end wall is arranged between the flange ring wall and the pipeline ring wall, and a ring-shaped sealing gasket is arranged in a hollow cavity which is defined by the flange ring wall, the pipeline ring wall and the circular ring end wall. According to the leaking stopping device for the sulfur hexafluoride gas delivery pipeline, the leaking stopping for the sulfur hexafluoride gas can be achieved by the jacketing and the ring-shaped sealing gasket without shutting off the power, the construction cycle is short, the sealing effect is good, and the leaking stopping device can be used for a long time, besides, the pipeline wall serves as a supporting point of the jacketing, so that insulators in a connecting flange of the pipeline can not be extruded to enlarge leaking points.
Description
One. technical field: the utility model relates to a kind of leakage-baffling device, particularly relates to a kind of sulfur hexafluoride gas conveyance conduit leakage-baffling device.
Two. background technique: sulfur hexafluoride gas is widely used in high pressure, the electric equipment of ultrahigh pressure as the insulating medium of a new generation, and leaking will appear in long-play; Leakage will cause dust, moisture to get into; At present, the mode of changing parts is still adopted in leak stopping, wastes time and energy; And, cause great economic loss and potential safety hazard owing to can not in time handle by the influence of power system operating mode.
Three. the model utility content:
The utility model technical problem to be solved is: overcome the deficiency of existing technology, a kind of simple in structure, easy to use and sulfur hexafluoride gas conveyance conduit leakage-baffling device that plugging effect is good is provided.
The technological scheme of the utility model is: a kind of sulfur hexafluoride gas conveyance conduit leakage-baffling device, contain involucrum, and said involucrum is a two halves formula structure; Be fixedly connected through connecting bolt; Said involucrum contains pipeline ring wall and flange ring wall, and the diameter of said flange ring wall is greater than the diameter of said pipeline ring wall, and; Be provided with the annulus end wall between said flange ring wall and the pipeline ring wall, be provided with Gask-O-Seal in the cavity that said flange ring wall, pipeline ring wall and annulus end wall surround.
Said connecting bolt is four, and both sides are uniformly distributed with.
The beneficial effect of the utility model is:
1, the utility model need not have a power failure through involucrum and Gask-O-Seal and can carry out the sulfur hexafluoride gas leak stopping; Its short construction period, good sealing effect can use for a long time; Involucrum is the strong point with the tube wall in addition, can not enlarge leakage point to the extruding of pipeline adpting flange inner insulator.
2, the utility model involucrum adopts two halves formula structure, processing and dismounting easily, and high working efficiency, user cost is lower.
3, the utility model is simple in structure, easy to use and plugging effect is good, is easy to promote, and has good economic benefit.
Four. description of drawings:
Fig. 1 is the structural representation of sulfur hexafluoride gas conveyance conduit leakage-baffling device;
Fig. 2 is the left view of sulfur hexafluoride gas conveyance conduit leakage-baffling device shown in Figure 1.
Five. embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, 1-pipeline ring wall, 2-Gask-O-Seal, 3-flange ring wall, 4-connecting bolt, 5-annulus end wall.
Sulfur hexafluoride gas conveyance conduit leakage-baffling device contains involucrum; Involucrum is a two halves formula structure, is fixedly connected through connecting bolt 4, and involucrum contains pipeline ring wall 1 and flange ring wall 3; The diameter of flange ring wall 3 is greater than the diameter of pipeline ring wall 1; And, be provided with annulus end wall 5 between flange ring wall 3 and the pipeline ring wall 1, be provided with Gask-O-Seal 2 in the cavity that flange ring wall 3, pipeline ring wall 1 and annulus end wall 5 surround.Connecting bolt 4 is four, and both sides are uniformly distributed with.
During use, the involucrum clip is on the adpting flange of sulfur hexafluoride gas conveyance conduit, wherein; Pipeline ring wall 1 clip is on the tube wall of conveyance conduit; Flange ring wall 3, annulus end wall 5 and Gask-O-Seal 2 clips are realized integral sealing on the adpting flange of conveyance conduit, thereby good sealing effect.
