Description
Technical field
The utility model relates to the axle head mechanical seal that is used for running shaft, particularly a kind of integrated mechanical sealing that carries the resistance seal ring.
Background technique
Present axle head mechanical seal to running shaft, the mechanical seal that the mechanical seal that the seal face separation structure is arranged of public use, seal face are assembled into integrative-structure, there is the artificial inefficacy factor of installing in the wherein mechanical seal of seal face separation structure, and it is unreliable to seal; The seal face integrated mechanical sealing, eliminated artificial installation inefficacy factor, and material good seal to cleaning, but to mortar with when containing the sealing of granule materials, because of mortar with contain granule materials and easily enter between the dynamic and static seal face, can cause damage, so sealing effect is bad to seal face.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of integrated mechanical sealing that carries the resistance seal ring is provided, it is to be assembled on the basis of integrative-structure at seal face, increased the obstruction seals ring, when sealing mortar and containing granule materials, can be effectively with the outside most mortar of mechanical seal with contain particulate blocking, thereby it is minimum that particle is reduced to the damage of the seal face of mechanical seal inside, sealing effect is long-acting reliable.
Above-mentioned purpose of the present utility model is realized by following technological scheme: a kind of integrated mechanical sealing that carries the resistance seal ring, be provided with the end surface mechanical sealing that is assembled into integrative-structure, wherein the internal diameter of the rotary packing ring of axial end sealing fits tightly with the axle sleeve external diameter by pin and O type rubber ring, the internal diameter maintenance gap of the external diameter of rotary packing ring and rigid gland ring; The external diameter of the stationary seal ring of axial end sealing fits tightly by the internal diameter of pin and O type rubber ring and rigid gland ring, and the internal diameter of stationary seal ring and axle sleeve external diameter keep the gap; Moving, the stationary seal ring seal face contacts relatively, under the effect of elastic compensating element, fit tightly and slide relative arranged, rigid gland ring and driving sleeve are that the bolt by locking ring and positioning block is connected to form one, it is characterized in that being provided with the resistance seal ring between seal face and sealed material, and it is gapped with seal face, the local end face in the outside of resistance seal ring edge direction, by pressing plate and screw and have axial end stationary seal ring assembly, anti-rotation, locating slot, spring, the internal face of the rigid gland ring of O type rubber ring structure is fastenedly connected, the inner ring cutting edge of resistance seal ring is towards material, fits tightly and slide relative with the cylindrical of the rigidity axle sleeve of mechanical seal.
Advantage of the present utility model and effect:
The resistance seal ring is placed between seal face and the sealed material, and do not contact with seal face.Can effectively sealed material be intercepted with seal face and separate, the liquid of salable again cooling simultaneously and lubrication and seal end face, and do not enter in the sealed material.The local end face in the outside of the edge direction of resistance seal ring, be fastenedly connected by pressing plate and screw and the internal face that has a rigid gland ring of axial end stationary seal ring assembly, anti-rotation, locating slot, spring, O type rubber ring structure, the inner ring cutting edge of resistance seal ring is towards material, fit tightly and slide relative with the cylindrical of the rigidity axle sleeve of mechanical seal, to realize together effectively sealing.Wherein the internal diameter of the rotary packing ring of axial end sealing fits tightly by pin and O type rubber ring and axle sleeve external diameter, the internal diameter of the external diameter of rotary packing ring and rigid gland ring keeps the gap, the external diameter of the stationary seal ring of axial end sealing fits tightly by the internal diameter of pin and O type rubber ring and rigid gland ring, the internal diameter of stationary seal ring and axle sleeve external diameter keep the gap, moving, the stationary seal ring seal face contacts relatively, under the effect of elastic compensating element, fit tightly and slide relative, to realize together effectively sealing, the above effective sealing of twice like this, its suitable material, pressure range is wide, externally during the variation of environment factor, especially to thickness with when containing the sealing of granule materials, place the resistance seal ring in the integrated mechanical sealing, can realize externally intercepting mortar and contain particle, internally sealing, save the liquid of cooling and lubrication and seal end face, simultaneously because of the isolated of rigidity axle sleeve arranged, axle does not does not wear and tear, and improve, improve the working environment and the life-span of end face sealing ring, the above sealing of two pass simultaneously, also be raising to safety guarantee, the sealing reliability height.The obstruction seals ring material can be rubber, teflon, polyamine fat etc., and can add the elastic compensating element according to actual conditions.So promptly dwindled physical dimension, stopped the human failure factor again and improved the reliability of sealing.Its suitable material, pressure range are wide, externally during the variation of environment factor, especially to thickness with when containing the sealing of granule materials, place the resistance seal ring in the integrated mechanical sealing, can play the effect of effective sword sealing, and can between resistance seal ring and end face sealing ring, feed sealing fluid, improve the working environment and the life-span of seal ring, dynamic and static in addition seal ring seal end face contacts relatively, under the effect of elastic compensating element, fitting tightly and slide relative, to realize effective sealing, also is significantly improving safety guarantee simultaneously.
Description of drawings
Fig. 1 is the utility model general structure schematic representation.
Embodiment
Referring to Fig. 1, resistance seal ring 4 places between seal face 10,11 and the sealed material, and does not contact with seal face 10,11.Can effectively sealed material be intercepted with seal face and separate, the liquid of salable again cooling simultaneously and lubrication and seal end face, and do not enter in the sealed material.The local end face in the outside with resistance seal ring 4 edge directions, be fastenedly connected with the internal face that has the rigid gland ring 1 of axial end stationary seal ring 11, anti-rotation, locating slot, spring 13, O type rubber ring 12 structures by pressing plate 2 and screw 3, the inner ring cutting edge of resistance seal ring 4 is towards material, fit tightly and slide relative with the cylindrical of the rigidity axle sleeve 6 of mechanical seal, realization externally intercepts mortar and contains particle, internally seals, saves the liquid of cooling and lubrication and seal end face.Wherein the internal diameter of the rotary packing ring 10 of axial end sealing fits tightly with axle sleeve 6 external diameters by pin 9 and O type rubber ring 8, the internal diameter of the external diameter of rotary packing ring 10 and rigid gland ring 1 keeps the gap, the external diameter of the stationary seal ring 11 of axial end sealing fits tightly by the internal diameter of pin and O type rubber ring 12 and rigid gland ring 1, the internal diameter of stationary seal ring 11 and axle sleeve 6 external diameters keep the gap, moving, the stationary seal ring seal face contacts relatively, under the effect of elastic compensating element 13, fit tightly and slide relative, rigid gland ring 1 and driving sleeve 6 are that the bolt 16 by locking ring 14 and positioning block 15 is connected to form one, to realize the live end face seal.17 also is O type rubber ring.
