Abstract
The invention discloses a fluoroplastic sealing ring. The fluoroplastic sealing ring comprises a sealing ring body. The sealing ring body is connected with an upper sealing end face and a lower sealing end face and comprises an outer annular ring main body and an inner hollow ring main body. The outer annular ring main body comprises a stainless steel outer circumference face and an inner circumference fluoroplastic face. The stainless steel outer circumference face achieves the wrapping effect on the inner circumference fluoroplastic face. By means of the fluoroplastic sealing ring, the sealing efficiency can be improved, corrosion of external impurities to a sealed workpiece can be effectively prevented, and meanwhile the fluoroplastic sealing ring has the good temperature resistance, the good pressure resistance and the good abrasion resistance.

It is the fluoroplastics of the new melt-processable of comparison, the fusing point of PFA is high, and density is 2.13 grams/cc to 2.16 grams/cube
Centimetre, PFA is heat-resisting, cold-resistant, chemical stability, mechanicalness, insulating properties, self lubricity, folding resistance, resistance to cracking are excellent.
A kind of optimal technical scheme, described inner periphery fluoroplastics face structure, internal diameter width 25 millimeters to 30 millimeters it
Between, external diameter width is between 35 millimeters to 50 millimeters.
Rustless steel outer circumference surface structure plays coating function to inner periphery fluoroplastics face structure, and inner periphery fluoroplastics face is tied
Structure is applied with a centripetal force.For the ease of applying external force, outside the rustless steel of described upper and lower two end faces of sealing ring body
Projection is provided with periphery structure, projection is easy to apply the external force to encapsulant, plays better seal effect.
Because the coefficient of expansion of fluoroplastics is the several times of stainless steel material, it is also provided with not on described exterior annular circle body
Rust steel fracture, is easy to expanding with heat and contract with cold for stainless steel material.
Circular O-ring is also provided with described inner periphery fluoroplastics face structure, O-ring is also adopted by fluoroplastics making, and
Filled with glass fibre or carbon fiber, 0 described type circle can also replace with rubber ring.
Sealing lip is provided with O-ring, sealing lip plays sealing function to sealed pipe fittings, and described sealing lip is using poly-
Tetrafluoroethene and polyparaphenylene phenol mixing material make, polyparaphenylene phenol, are ideal resistance in the industries such as metallurgy, chemical industry
Mill, encapsulant, high life, high temperature resistant, meanwhile, polyparaphenylene heat stability is good, and corrosion resistance, self-lubricating property is better than
Molybdenum bisuphide and graphite, the strand of PPL, due to very big rigidity and regularity makes it in not melting insoluble, and itself is processed into
Type is difficult, need to fill other materials and be blended to use.
Meanwhile, circular collar is provided with described rustless steel outer circumference surface structure, it is provided with described back-up ring
Buckle, plays the purpose of fastening rustless steel outer circumference surface structure.
A kind of optimal technical scheme, described back-up ring quantity is 2, and the buckle quantity arranged on back-up ring is also 2.
The invention has the beneficial effects as follows：A kind of fluoroplastics sealing ring of the present invention, it is possible to increase leakage efficiency, effectively tissue are outer
Corrosion of boundary's impurity to sealing workpiece, meanwhile, fluoroplastics sealing ring has good heatproof, pressure and anti-wear performance, compressive resistance
By force, long service life, efficiency high, while handling ease, is particularly suited for various strong corrosive environments.
