Description
Technical field
The present invention relates to seal nipple assembly.
Background technology
Gas insulated transformer substation (GIS) is that sulfur hexafluoride (SF6) gas using insulating properties and arc extinction performance excellence is made
For insulating and arc-extinguishing medium, and all of component of high voltage electrical apparatus is sealed in the metal cylinder of ground connection, with traditional open power transformation
Station compare there is time between overhauls(TBO) length, maintenance workload is little, installation is rapid, operating cost is low, without advantages such as electromagnetic interference.Current
Transformer station is mostly gas insulated transformer substation, but along with gas insulated transformer substation puts into operation in a large number, owing to seal nipple assembly produces
And the reason such as mounting process is not in place, the gas leak phenomenon causing equipment air chamber is increasingly severe, therefore must in regular maintenance
The serious equipment air chamber that leaks gas must be carried out QI invigorating, sometimes need the equipment air chamber of low pressure alarming is rushed to repair, the most anxious
Need the seal nipple assembly of a kind of good seal performance.
Summary of the invention
The technical problem to be solved in the present invention is to provide the seal nipple assembly of a kind of good seal performance.
The technical solution of the present invention is to provide a kind of seal nipple assembly with following structure, including being provided with
The left joint of one sealing surface and the right connector being provided with secondary sealing area, described primary sealing area is provided with boss, described second
Sealing surface is provided with the mounting groove matched with boss, it is characterised in that: described primary sealing area is provided with annular groove, described
Two sealing surfaces are provided with the annular flange flange matched with annular groove, and described mounting groove opening part sidewall is provided with draw-in groove, described card
Being provided with the first sealing ring in groove, the first described sealing ring cross sectional shape is trapezoidal, and the first sealing ring is positioned at trapezoidal waist edge
Sidewall 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 flange
So that draw-in groove deforms and the first sealing ring presses to the annular projection of boss.
Preferably, described draw-in groove 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 side that the first described sealing ring shape is less contacts in draw-in groove, makes both combinations more
Closely.Described annular groove is provided with the second sealing ring coordinated with annular flange flange in the side of round platform, makes annular groove
Tightr with coordinating at annular flange flange.
Preferably, described annular flange flange and draw-in groove are an entirety and the side by welding near the side of annular flange flange
Formula is fixed on right connector, and different materials i.e. can be selected jointly to make right connector, makes the morphotropism at deformation more preferable, improves
Sealing property.
Preferably, described right connector outer side seal is combined with the nut being threaded on left joint, makes left and right joint
Connect more preferably, and the pressure between the left and right joint of energy, it is ensured that sealing property is higher.
Preferably, the sealing member having cross sectional shape to be " N " font of conflicting between described round platform and mounting groove, described is close
Sealing one end part contacts between round platform sidewall and mounting groove sidewall, supports between described sealing member bending part and round platform end face
Touch the 3rd sealing ring, the 4th sealing ring of conflicting between described sealing member bending part and mounting groove bottom land, close by " N " font
Sealing not only considerably increases the sealing property of round platform and mounting groove, and owing to degree deformation can be determined in " N " font, increases and seal
Effect, sealing ring substantially increases sealing effectiveness.
After using above structure, the seal nipple assembly of the present invention, compared with prior art, have the advantage that and pass through
Round platform and mounting groove carry out 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 and seals, and the first described sealing ring and round platform sidewall extrusion form three seals, are passing through draw-in groove
Inner annular projection extruding annular flange flange, not only makes annular groove and annular flange flange be tightly combined, and makes draw-in groove deformation allow draw-in groove squeeze
Press the first sealing ring, considerably increase the sealing effectiveness between the first sealing ring and round platform sidewall, and do not affect round platform and put into peace
In tankage.
