The utility model provides a rotary seal connects has installation, maintenance simple, long service life, and the characteristics that sealing performance is reliable do not produce the external leakage of fluid medium when the fluid medium that comes to the rotary equipment with static pipe-line transportation, can be used to fields such as tobacco, metallurgy, chemical industry, oil, rubber, building materials, grain.
Description
Affiliated technical field
The utility model discloses a kind of SEALING FITTING of liquid delivery tube, particularly rotatable seal joint structure.
Background technique
Existing many mechanical seal device adopt spring as the elastic compensating element mostly at present, easily produce corrosion and plastic deformation, and the elastic force that is produced is skewness also, thereby can strengthen the wearing and tearing of stationary seal ring, reduces the working life of product.Seal ring adopts graphite material to process through impregnated phenolic resin mostly, and the seal ring porosity of making like this is big, and intensity, hardness are low, wear no resistance, and in use can influence the working life of complete machine.The existing mechanical sealed product, adopt rolling bearing supporting shaft and housing, rolling bearing in use necessary regularly filling lubricant oil or grease, increased maintenance, repair intensity, particularly in the high temperature use occasion, the easy sintering of lubricant grease that uses causes the stuck even damage of mechanical seal product.
Summary of the invention
For overcoming the deficiency that existing seal arrangement exists, the utility model proposes a kind of rotary seal joint, the utility model comprises housing, elasticity single file black box and hollow rotating shaft, housing is provided with boss, gland nut and tighten the end that nut is installed in housing successively, elastic packing assembly and hollow rotating shaft axially are installed in the other end of housing, the elastic packing assembly is fixed its mounting point by the boss of housing, the self-lubricating graphite bearing is installed in the outer ring of hollow rotating shaft, graphite-seal ring is equipped with at elastic packing assembly and hollow rotating shaft opposing end faces place, graphite-seal ring is installed in the spacer that has groove, and spacer is fixed by the thrust screw that is arranged in the groove.
Described elastic packing assembly adopts bellows as elastic element.
The utility model proposes the rotary seal joint and have installation, simple, the long service life of maintenance, repair, the sealability reliable characteristics, utilize flowing medium that rotary seal joint of the present utility model comes static line transportation when rotating equipment is carried, do not produce the external leakage of flowing medium, can be used for fields such as tobacco, metallurgy, chemical industry, oil, rubber, building materials, grain.

Accompanying drawing is the structural representation of the utility model rotary seal joint.
Among the figure, 1-jack panel, 2-tighten nut, 3-elastic packing assembly, 4-graphite-seal ring, 5-thrust screw, 6-spacer, 7-self-lubricating graphite bearing, 8-housing, 9-hollow rotating shaft
Embodiment
As shown in the figure, present embodiment comprise gland nut (1), tighten nut (2), elastic packing assembly (3), graphite-seal ring (4), thrust screw (5), spacer (6), self-lubricating graphite bearing (7), housing (8), hollow rotating shaft (9).Housing (8) is used self-lubricating graphite bearing (7) supporting of being installed above the hollow rotating shaft (9), makes can produce relative rotation between hollow rotating shaft (9) and the housing (8) and do not rotate interference.Adopt self-lubricating graphite bearing (7) to substitute traditional rolling bearing, need not annotate bearing oil or grease, thereby can avoid high temperature the time, because lubricant oil or grease are because the stuck and damage that high temperature sintering causes.Gland nut (1) and tighten nut (2) and use screw thread and be installed on the housing (8).
Graphite-seal ring (4) is contained in the spacer (6), and spacer has groove in (6), graphite-seal ring (4) can be produced move axially by the effect of thrust screw (5) between the two and does not produce radial displacement.The seal face of graphite-seal ring (4) and the seal face of hollow rotating shaft (9) fit tightly, the seal face of another seal face and elastic packing assembly (3) fits tightly, elastic packing assembly (3) adopts bellows as elastic element, the outer ring of graphite-seal ring (4) is bearing on the housing (8), and the tail end of bellows elastic packing assembly (3) is used housing (8) supporting.Graphite-seal ring (4) is used the axial elasticity power that ripple elastic packing assembly (3) is produced, allow two seal faces after producing the relative movement wearing and tearing, can use the automatic compensation that elastic force produces and keep combining closely with the seal face of hollow rotating shaft (9) and bellows elastic packing assembly (3) always, make working medium after pipeline enters hollow rotating shaft, externally not produce leakage.Bellows elastic packing assembly (3) both as Sealing also as elastic component, make that the structure of sealed product is more compact, sealability is more reliable.After graphite-seal ring (4) mainly adds multiple hard metal and nonmetallic material by graphite material, form through more than the 3000 high temperature powder metallurgy technology compactings of spending, hardness intensity height, self-lubricating property is good, is well positioned to meet the sealing usage requirement.
The technical order that present embodiment reaches is as follows
Ambient temperature :-20 ℃～40 ℃;
Sealing medium: steam, water, oil, and weak erosive medium;
Sealed medium pressure: 0～1.6MPa;
Sealing medium temperature :-20 ℃～320 ℃;
Sealing pair relative rotation speed :≤100r/min
Claims (2)
1, a kind of rotary seal joint, comprise housing (8), gland nut (1) and tighten the end that nut (2) is installed in housing (8) successively, it is characterized in that housing (8) is provided with boss, elastic packing assembly (3) and hollow rotating shaft (9) axially are installed in the other end of housing (8), elastic packing assembly (3) is fixed its mounting point by the boss of housing (8), self-lubricating graphite bearing (7) is installed in the outer ring of hollow rotating shaft (9), elastic packing assembly (3) is equipped with graphite-seal ring (4) with hollow rotating shaft (9) opposing end faces place, graphite-seal ring (4) is installed in the spacer (6) that has groove, and spacer (6) is fixing by the thrust screw (5) that is arranged in the groove.
2, rotary seal joint according to claim 1 is characterized in that elastic packing assembly (3) adopts bellows as elastic element.
