Description
Technical field
The present invention relates to a kind of seal nipple.
Background technology
Gas insulated transformer substation (GIS) is that sulfur hexafluoride (SF6) gas using insulating properties and arc extinction performance excellence is as insulation and arc-extinguishing medium, and all of component of high voltage electrical apparatus is sealed in the metal cylinder of ground connection, there is compared with traditional open transformer station 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, the reason such as produce and mounting process is not in place due to seal nipple, the gas leak phenomenon causing equipment air chamber is increasingly severe, therefore 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, be badly in need of the seal nipple of a kind of good seal performance the most on the market.
Summary of the invention
The technical problem to be solved in the present invention is to provide the seal nipple of a kind of good seal performance.
The technical solution of the present invention is, a kind of seal nipple with following structure is provided, including being provided with the left joint of primary sealing area and being provided with the right connector of secondary sealing area, described primary sealing area is provided with the boss of cylinder, described secondary sealing area is provided with the mounting groove matched with boss, described primary sealing area is provided with annular groove, described secondary sealing area is provided with the annular flange flange matched with annular groove, described mounting groove opening part sidewall is provided with draw-in groove, the first sealing ring it is provided with in described draw-in groove, conflict to have between described annular flange flange with the first sealing ring and be connected ring, in described annular groove and be located remotely from the side of boss and be provided with extruding annular flange flange so that connecting ring to extrude the annular projection of the first sealing ring.
Preferably, described draw-in groove cross sectional shape is " V " font and the sidewall away from annular flange flange is perpendicular to mounting groove inwall, strengthen away from the sealing effectiveness at annular flange flange, and coordinate with being connected ring, improve sealing effectiveness further, the first described sealing ring cross sectional shape is water-drop-shaped, and the side that the first described sealing ring shape is less contacts in draw-in groove, makes both combinations tightr.
Preferably, described annular groove is provided with the second sealing ring coordinated with annular flange flange in the side of round platform, makes cooperation at annular groove and annular flange flange tightr.
Preferably, described annular flange flange and draw-in groove are an entirety near the side of annular flange flange and are fixed on right connector by the way of welding, different materials i.e. can be selected jointly to make right connector, make the morphotropism at deformation more preferable, improve 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 that between described round platform and mounting groove, conflict has cross sectional shape to be " N " font, described sealing member one end part contacts between round platform sidewall and mounting groove sidewall, conflict the 3rd sealing ring between described sealing member bending part and round platform end face, conflict the 4th sealing ring between described sealing member bending part and mounting groove bottom land, the sealing property of round platform and mounting groove is not only considerably increased by the sealing member of " N " font, and owing to degree deformation can be determined in " N " font, increasing sealing effectiveness, sealing ring substantially increases sealing effectiveness.
After using above structure, the seal nipple of the present invention, compared with prior art, have the advantage that and carry out substantially sealed off by boss and mounting groove, by being arranged on the annular groove of primary sealing area and being arranged on the annular flange flange formation second sealing of secondary sealing area, the first described sealing ring forms three seals with plateau sidewall extruding, annular flange flange is being extruded by draw-in groove inner annular projection, annular groove and annular flange flange is not only made to be tightly combined, and make connection ring extrude the first sealing ring, considerably increase the sealing effectiveness between the first sealing ring and plateau sidewall, and do not affect boss and put into mounting groove.
