Further, said sealing lip cross section is V-shaped, and in said sealing lip, is provided for lip-type sealing ring is provided the annular spring of pretightening force.Change the sealing of many lips road formula into through sealing configuration, effectively reduced the wearing and tearing of flexible seal device, and to increase annular spring be the dynamic compensation that lip-type sealing ring provides wear extent, operating life is prolonged greatly original O type circle.
Preferably, between said lip-type sealing ring and the said interior ring axle sleeve is set, and said axle sleeve is through Wear-resistant Treatment, so that the wear-resisting property of axle sleeve strengthens.Through between interior ring and lip-type sealing ring, increasing axle sleeve, and Wear-resistant Treatment is carried out on the surface of axle sleeve, increased the wear resistance of axle sleeve, further protected interior ring.
Preferably; Said flexible seal device has quadruplet; And said intake pipe assembly and said return pipe assembly respectively seal through the said flexible seal device of two covers; Said intake pipe assembly and said return pipe assembly all are supported and fixed on the said interior ring through rotary bearing and bearing support, and said intake pipe assembly is connected as a whole with said return pipe assembly through bolt.
Preferably, said lip-type sealing ring has three sealing lips.
Preferably, said axle sleeve is through Wear-resistant Treatment, and said Wear-resistant Treatment is to inject titanium nitride in surface spraying of said axle sleeve or ion.
Preferably, said lip-type sealing ring adopts teflon to make.Because (F4 PTFE) has a series of good usabilities to teflon: high temperature resistant-long-term serviceability temperature 200～260 degree, low temperature resistant-still soft when-100 spend; Corrosion-resistant-ability chloroazotic acid and all organic solvents; The aging life-span of the best in weatherability-plastics; High friction factor (0.04) with minimum in the plastics; Viscosity-have minimum surface tension and do not adhere to any material in the solid material not; Nonhazardous-have physiology inertia; Excellent electrical properties is desirable C class F insulating material F, and one deck that newspaper is thick just can stop the high pressure of 1500V; Also more smooth than ice.
The beneficial effect of the utility model is: change the formula sealing of many lips road into through the sealing configuration with original O type circle; Can, play flexible seal device dual or multi-sealed effect when working; The leakage of effectively anti-sealing hinge; Increasing annular spring simultaneously is the dynamic compensation that lip-type sealing ring provides wear extent, and operating life is prolonged greatly, the working life of also having improved whole water hinge simultaneously; Through between interior ring and lip-type sealing ring, increasing axle sleeve; And the surface of axle sleeve carried out Wear-resistant Treatment; Increased the wear resistance of axle sleeve; Further protected interior ring, the contrast existing technology, that this water hinge has is simple in structure, the sealing reliable, the friction pair difficulty of processing is little, cost is low, have compensation rate between the friction pair, working condition requirement is low and the advantage of long working life.
