There is the first sealing ring, in described annular groove and be located remotely from the side of boss and be provided with extruding annular flange flange so that draw-in groove deformation
Extrude the annular projection of the first sealing ring.
Preferably, the cross sectional shape of described draw-in groove is "U" shaped.
Preferably, the cross sectional shape of the first described sealing ring is water-drop-shaped, and the first described sealing ring shape is less
Side contacts in draw-in groove.
Preferably, described annular groove is provided with the second sealing ring coordinated with annular flange flange in the side of round platform.
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.
Preferably, described right connector outer side seal is combined with the nut being threaded on left joint.
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.
Preferably, the 3rd sealing ring of conflicting between described sealing member bending part and round platform end face, described sealing member folding
Conflict the 4th sealing ring between crook and mounting groove bottom land.
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 draw-in groove deformation allow draw-in groove extruding the
One sealing ring, considerably increases the sealing effectiveness between the first sealing ring and round platform sidewall, and does not affect round platform and put into mounting groove
In.

Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Referring to shown in Fig. 1, Fig. 2 and Fig. 3, the seal nipple of the present invention, including the left joint 1 being provided with primary sealing area 11
Be provided with the right connector 2 of secondary sealing area 21, described primary sealing area 11 is provided with the boss 12 of cylinder, and described second is close
Front cover 21 is provided with the mounting groove 22 matched with boss 12, and described primary sealing area 11 is provided with annular groove 3, and described second is close
Front cover 21 is provided with the annular flange flange 4 matched with annular groove 3, and described mounting groove 22 opening part sidewall is provided with draw-in groove 5, described
The first sealing ring 6 it is provided with, in described annular groove 3 and be located remotely from the side of boss 12 and be provided with extruding convex annular in draw-in groove 5
Edge 4, so that the annular projection 7 of draw-in groove 5 deformable squeeze the first sealing ring 6, carries out substantially sealed off by round platform and mounting groove 22, logical
Cross the annular groove 3 being arranged on primary sealing area 11 and form second sealing with the annular flange flange 4 being arranged on secondary sealing area 21,
The first described sealing ring 6 forms three seals with round platform sidewall extrusion, by the protruding 7 extruding annulars of draw-in groove 5 inner annular
Flange 4, not only makes annular groove 3 and annular flange flange 4 be tightly combined, and makes draw-in groove 5 deformation allow draw-in groove 5 extrude the first sealing ring 6,
Considerably increase the sealing effectiveness between the first sealing ring 6 and round platform sidewall, and do not affect round platform and put into mounting groove 22.
The cross sectional shape of described draw-in groove 5 is "U" shaped, and convenient installation, the cross sectional shape of the first described sealing ring 6 is
