Inside being provided with the first wedge-type seal circle, described round platform sidewall is provided with the second draw-in groove, described relative to the position of the first draw-in groove
Being provided with the second wedge-type seal circle conflicted with the first wedge-type seal circle in two draw-in grooves, described annular groove is interior and is located remotely from circle
The side of platform is provided with extruding annular flange flange so that the first wedge-type seal circle extrudes the annular projection of the second wedge-type seal circle.
Preferably, described annular groove is provided with the first 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.
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 the first wedge-type seal circle squeeze
Press the second wedge-type seal circle, considerably increase sealing effectiveness, and do not affect round platform and put into mounting groove.
