Description
Technical field
The utility model belongs to swivel joint, particularly a kind of friction plate dust protected swivel joint.
Background technique
Swivel joint on the cement slurry spraying machine of the industries such as Steel Refining stove gun, mine, building; cleaning dirtyly after usually can or using because of cement slurry seepage be bonded on inner main seal part after causing cement slurry to solidify; thereby cause that swivel joint crosses quick-wearing and abnormal leakage; cause the swivel joint lost of life; change frequent; impact is produced, waste physical resources and financial resources.
Model utility content
For above-mentioned the deficiencies in the prior art, provide a kind of friction plate dust protected swivel joint of simple in structure, wear-resistant, good seal performance.
The technical solution of the utility model is: a kind of friction plate dust protected swivel joint, comprise housing, axle, nut, back-up ring, friction plate assembly, the first seal ring, packing ring, elastic axis card, clutch shaft bearing, the second bearing, the second seal ring, rotation stopping screw, Leak hole, the 3rd seal ring, it is characterized in that: described friction plate assembly comprises the axle collar, orifice ring, described orifice ring is arranged in the grooved seal hole of housing, the described axle collar is arranged in the groove of axle outer end, in the groove of described axle, be provided with the second seal ring, back-up ring and the second seal ring are friction sealed, between described axle external diameter and housing internal diameter, be provided with clutch shaft bearing, the second bearing, between described clutch shaft bearing and the groove of axle, be provided with elastic axis card, between described axle groove and housing internal diameter, be provided with the first seal ring, described housing, axle is linked to be an entirety by nut, described nut is provided with rotation stopping screw, described housing is provided with Leak hole, Leak hole outer end is provided with the 3rd seal ring.
The utility model advantageous effect: this friction plate dust protected swivel joint; adopt orifice ring to be embedded in grooved seal hole, hole; the axle collar is embedded in the structure of axle grooved seal axle; utilizing the axle collar and the friction of orifice ring plane gapless mazy type to prevent dust can stop granule foreign to enter primary seal position completely; effectively protect primary seal, thereby this model utility good dustproof effect, surface friction drag is low; self-cleaning property is good, long service life.
