In: between described round platform and mounting groove conflict have cross sectional shape to be " N " font sealing member, described sealing member bending part with
Conflict between round platform end face the first sealing ring, the second sealing ring of conflicting between described sealing member bending part and mounting groove bottom land,
Described sealing member one end part contacts between round platform sidewall and mounting groove sidewall, is provided with Self-resetting bullet in described left joint
Block, described right connector is provided with the unlatching block conflicted with Self-resetting bullet block.
Preferably, described primary sealing area is provided with annular groove, and described secondary sealing area is provided with and annular groove phase
The annular flange flange joined, described mounting groove opening part sidewall is provided with draw-in groove, is provided with the 3rd sealing ring in described draw-in groove, described
In annular groove and be located remotely from the side of round platform and be provided with extruding annular flange flange so that the ring of draw-in groove deformable squeeze the 3rd sealing ring
Shape is protruding, carries out substantially sealed off by round platform and mounting groove, by being arranged on the annular groove of primary sealing area and being arranged on the
The annular flange flange of two sealing surfaces forms second and seals, and it is close that the first described sealing ring and round platform sidewall extrusion form the 3rd road
Envelope, is extruding annular flange flange by draw-in groove inner annular projection, is not only making annular groove and annular flange flange be tightly combined, and make draw-in groove
Deformation allows draw-in groove extrude the 3rd sealing ring, considerably increases the sealing effectiveness between the first sealing ring and round platform sidewall, and not shadow
Ring round platform and put into mounting groove.
Preferably, described annular groove is provided with the 4th sealing ring coordinated with annular flange flange in the side of round platform,
Make cooperation at annular groove and annular flange flange tightr.
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.
After using above structure, the seal nipple of the present invention, compared with prior art, have the advantage that by " N " word
The sealing member of shape 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
Adding sealing effectiveness, sealing ring substantially increases sealing effectiveness, and when left and right joint separates, Self-resetting bullet block separates with opening block
And Self-resetting bullet block can make pathway closure by elasticity from master reset, it is ensured that sealing.
