Description
Technical field
The present invention relates to seal nipple component.
Background technology
Gas insulated transformer substation (GIS) is made using excellent sulfur hexafluoride (SF6) gas of insulating properties and arc extinction performance
For insulation and arc-extinguishing medium, and all component of high voltage electrical apparatus are sealed in the metal cylinder of ground connection, with traditional open power transformation
Stand compared to have the advantages that the time between overhauls(TBO) is long, maintenance workload is small, installation is rapid, operating cost is low, without electromagnetic interference.Current
Transformer station is mostly gas insulated transformer substation, but as gas insulated transformer substation largely puts into operation, because seal nipple component produces
And the reasons such as mounting process is not in place, cause the gas leak phenomenon of equipment air chamber increasingly severe, therefore must in regular maintenance
Equipment air chamber that must be serious to gas leakage carries out tonifying Qi, needs to rush to repair the equipment air chamber of low pressure alarming sometimes, i.e., anxious on the market
Need a kind of seal nipple component of good seal performance.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of seal nipple component of good seal performance.
The technical solution of the present invention is to provide a kind of seal nipple component with following structure, including provided with the
The left joint of one sealing surface and the right connector provided with secondary sealing area, described primary sealing area are provided with boss, and described second
Sealing surface is provided with the mounting groove to match with boss, it is characterised in that：Described primary sealing area is provided with annular groove, and described
Two sealing surfaces are provided with the annular flange to match with annular groove, and described mounting groove opening side wall is provided with neck, described card
The first sealing ring is provided with groove, the first described sealing ring cross sectional shape is trapezoidal, and the first sealing ring is located at trapezoidal waist edge
Side wall be oppositely arranged with plateau sidewall, in described annular groove and be located remotely from the side of boss and be provided with extruding annular flange
So that neck deforms and the first sealing ring is pressed to the annular projection of boss.
Preferably, described neck cross sectional shape is "U" shaped, convenient installation, good seal performance.The first described sealing
Ring cross-section is shaped as water-drop-shaped, and the described first less side of sealing loop-shaped is contacted in neck, both is combined more
Closely.Described annular groove is provided with the second sealing ring coordinated with annular flange in the side of round platform, makes annular groove
It is even closer with coordinating at annular flange.
Preferably, the side that described annular flange and neck are integral close to the side of annular flange and pass through welding
Formula is fixed on right connector, you can to select different materials right connector to be made jointly, is made the morphotropism at deformation more preferable, is improved
Sealing property.
Preferably, described right connector outer side seal is combined with the nut being threaded on left joint, makes left and right joint
Connection is more preferable, and the pressure between the left and right joint of energy, ensures that sealing property is stronger.
Preferably, the seal for having cross sectional shape to be " N " font is contradicted between described round platform and mounting groove, described is close
Sealing one end part is contacted between round platform side wall and installation groove sidewall, is supported between described seal bending part and round platform end face
The 3rd sealing ring is touched, the 4th sealing ring is contradicted between described seal bending part and mounting groove bottom land, passes through the close of " N " font
Sealing not only considerably increases the sealing property of round platform and mounting groove, and because " N " font can determine degree deformation, increase sealing
Effect, sealing ring substantially increase sealing effectiveness.
After above structure, seal nipple component of the invention, compared with prior art, there is advantages below：Pass through
Round platform and mounting groove progress are substantially sealed off, by being arranged on the annular groove of primary sealing area and being arranged on the ring of secondary sealing area
Shape flange forms second sealing, and the first described sealing ring forms three seals with round platform sidewall extrusion, passing through neck
The raised extruding annular flange of inner annular, is not only tightly combined annular groove and annular flange, and makes neck deformation allow neck to squeeze
The first sealing ring is pressed, considerably increases the sealing effectiveness between the first sealing ring and round platform side wall, and does not influence round platform and is put into peace
In tankage.
