Description
Technical field
The present invention relates to a kind of seal nipple.
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, due to seal nipple production and
The reasons such as mounting process is not in place, cause the gas leak phenomenon of equipment air chamber increasingly severe, therefore must be right in regular maintenance
The serious equipment air chamber of gas leakage carries out tonifying Qi, needs to rush to repair the equipment air chamber of low pressure alarming sometimes, i.e., is badly in need of one on the market
The seal nipple of kind 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 of good seal performance.
The technical solution of the present invention is to provide a kind of seal nipple with following structure, including close provided with first
The left joint of front cover and the right connector provided with secondary sealing area, described primary sealing area is provided with the boss of cylinder, described
Secondary sealing area is provided with the mounting groove to match with boss, and described primary sealing area is provided with annular groove, the described second sealing
Face is provided with the annular flange to match with annular groove, and described mounting groove opening side wall is provided with neck, set in described neck
There is the first sealing ring, being contradicted between described annular flange and the first sealing ring has connection ring, in described annular groove and position
Extruding annular flange is provided with the side away from boss so that connection ring extrudes the annular projection of the first sealing ring.
Preferably, described neck cross sectional shape is " V " font and the side wall away from annular flange is in mounting groove
Wall, strengthen away from the sealing effectiveness at annular flange, and coordinate with connection ring, further improve sealing effectiveness, described first
Sealing ring cross sectional shape is water-drop-shaped, and the described first less side of sealing loop-shaped is contacted in neck, combines both
It is even closer.
Preferably, described annular groove is provided with the second sealing ring coordinated with annular flange in the side of round platform,
Make cooperation at annular groove and annular flange even closer.
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 of the invention, compared with prior art, there is advantages below：Pass through boss
It is substantially sealed off with mounting groove progress, by being arranged on the annular groove of primary sealing area and being arranged on the convex annular of secondary sealing area
Edge forms second sealing, and the first described sealing ring extrudes to form three seals with plateau sidewall, is passing through neck inner ring
The raised extruding annular flange of shape, is not only tightly combined annular groove and annular flange, and connection ring is extruded the first sealing ring,
The sealing effectiveness between the first sealing ring and plateau sidewall is considerably increased, and does not influence boss and is put into mounting groove.
