Preferred according to the present invention, side relative with annular protrusion on described seal ring is provided with the annular small embossment coaxial with described seal ring, the height of described annular small embossment is 1mm-10mm.Annular small embossment improves the frictional force between surface of contact between washer portion and surface of contact, can improve sealing and the stability of Flange joint.
Preferred according to the present invention, the number of described annular small embossment is 1-10.
Preferred according to the present invention, described two flange tube heads are provided with annular groove, in described annular groove, are provided with seal ring.
Preferred according to the present invention, the width 0.1-1.5mm larger than the width of described annular groove of described annular protrusion.Annular protrusion can utilize the elastic allowance of annular protrusion slightly larger than annular groove, improves its sealing effect after tightening.
According to the present invention preferably, described annular protrusion top is stupefied through chamfered.The advantage herein designed is, is easy to annular protrusion and inserts in annular groove.
Preferred according to the present invention, described seal ring is quality of rubber materials or silica gel material.Quality of rubber materials or silica gel material seal ring make seal ring when ensureing also have certain elasticity when having higher-strength, improve the stability and seal that connect.
Advantage of the present invention is :-
1, plastics flange of the present invention connects sealing system, the annular protrusion of described seal ring is inserted in annular groove, for fixed seal ring, no longer need manually to fix cushion rubber, just can ensure not easily sideslip dislocation in installation process, effective quickening construction progress, time saving and energy saving, improve construction safety;
2, plastics flange of the present invention connects sealing system, does not need to overlap production mould more, practical, applied widely, and structure is simple, cheap;
3, plastics flange of the present invention connects sealing system, the annular protrusion of described seal ring is inserted in annular groove, play the effect of fixed seal ring, the seal ring slippage that can effectively prevent from seal ring in use causing because working pressure is large, misplace or tear, substantially prolongs the working life of seal ring.
