Description
Technical field
The present invention relates to seal nipple controllers.
Background technique
Gas insulated transformer substation (GIS) is made using excellent sulfur hexafluoride (SF6) gas of insulation performance 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 many advantages, such as the time between overhauls(TBO) is long, maintenance workload is small, installation is rapid, operating cost is low, without electromagnetic interference.Current
Substation is mostly gas insulated transformer substation, but as gas insulated transformer substation largely puts into operation, since seal nipple controller is raw
The reasons such as production and mounting process are not in place, cause the gas leak phenomenon of equipment gas chamber increasingly severe, therefore in daily maintenance
Tonifying Qi must be carried out to the serious equipment gas chamber of gas leakage, need to repair the equipment gas chamber of low pressure alarming sometimes, i.e., on the market
It is badly in need of a kind of seal nipple controller of good seal performance.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of seal nipple controller of good seal performance.
The technical solution of the invention is as follows, provides a kind of seal nipple having following structure, including valve, branching block
And seal nipple, the seal nipple include that the left connector equipped with primary sealing area and the right side equipped with secondary sealing area connect
Head, the primary sealing area are equipped with rotary table, and the secondary sealing area is equipped with the mounting groove to match with rotary table, and feature exists
In：Between the rotary table and mounting groove contradict have cross sectional shape be " N " font sealing element, the sealing element bending part with
The first sealing ring is contradicted between rotary table end face, contradicts the second sealing ring between the sealing element bending part and mounting groove slot bottom,
The sealing element one end part contacts between rotary table side wall and installation groove sidewall, and Self-resetting bullet is equipped in the left connector
Block, the right connector are equipped with the unlatching block contradicted with Self-resetting bullet block.
Preferably, the primary sealing area is equipped with annular groove, and the secondary sealing area is equipped with and annular groove phase
The annular flange matched, the mounting groove opening side wall are equipped with card slot, and third sealing ring is equipped in the card slot, described
In annular groove and the side of rotary table is located remotely from equipped with extruding annular flange so that the ring of card slot deformable squeeze third sealing ring
Shape protrusion, carried out by rotary table and mounting groove it is substantially sealed off, by annular groove and setting that primary sealing area is arranged in the
The annular flange of two sealing surfaces forms second sealing, and first sealing ring and rotary table sidewall extrusion formation third road are close
Envelope is squeezing annular flange by card slot inner annular protrusion, is not only being tightly combined annular groove and annular flange, and make card slot
Deformation allows card slot to squeeze third sealing ring, considerably increases the sealing effect between the first sealing ring and rotary table side wall, and not shadow
Rotary table is rung to be put into mounting groove.
Preferably, the annular groove is equipped with the 4th sealing ring cooperated with annular flange in the side of rotary table,
Make to cooperate at annular groove and annular flange even closer.
Preferably, the annular flange and card slot are integral close to the side of annular flange and by the sides of welding
Formula is fixed on right connector, it can is selected different materials that right connector is made jointly, is kept the morphotropism at deformation more preferable, improves
Sealing performance.
Preferably, the right connector outer side seal is combined with the nut being threaded on left connector, makes left and right connector
Connection is more preferable, and the pressure between energy left and right connector, guarantees that sealing performance is stronger.
After using the above structure, seal nipple of the invention has the following advantages that compared with prior art：Pass through " N " word
The sealing element of shape not only considerably increases the sealing performance of rotary table and mounting groove, and since " N " font can determine degree deformation, increases
Add sealing effect, sealing ring substantially increases sealing effect, and when left and right connector separation, Self-resetting bullet block is separated with block is opened
And Self-resetting bullet block can be such that channel closes by elasticity from master reset, ensure that leakproofness.
