Face is provided with the truncated cone-shaped mounting groove matched with round platform, and described primary sealing area is provided with annular groove, described secondary sealing area
Being provided with the annular flange flange matched with annular groove, described mounting groove opening part sidewall is provided with draw-in groove, is provided with in described draw-in groove
First sealing ring, in described annular groove and be located remotely from the side of round platform and be provided with some extruding annular flange flange so that mounting groove
The annular projection of sidewall slope extruding round platform sidewall.
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 of the present invention, compared with prior art, have the advantage that and pass through round platform
Carry out substantially sealed off with mounting groove, by being arranged on the annular groove of primary sealing area and being arranged on the convex annular of secondary sealing area
Edge forms second and seals, and the first described sealing ring and round platform sidewall extrusion form three seals, by draw-in groove internal ring
Shape projection extruding annular flange flange, not only makes annular groove and annular flange flange be tightly combined, and makes mounting groove sidewall slope extruding circle
Platform sidewall, considerably increases the sealing effectiveness between mounting groove sidewall and round platform sidewall, and does not affect round platform and put into mounting groove.
