Abstract
The utility model relates to a swivel joint with a new pattern seal structure which is used for the transformation from a connecting equipment rotation pipeline to a conveyance fluid, and is composed of a hollow shaft, a rolling bearing component, an O-shaped seal ring, an oil seal and a shell. The swivel joint adopts a radial flexible seal structure which is composed of the O-shaped seal ring and the oil seal. That the O-shaped seal ring (3) and the oil seal (4) are arranged between the hollow shaft (1) and the shell (5) ensures that the swivel joint has excellent sealing and is not easy to leak. So the service life can be improved seven times. The rolling bearing component (2) is installed between the hollow shaft (1) and the shell (5) to make the rotation flexible and reliable. So the abrasion is small. The volume reduces one third of the original volume, and the weight is light.
Description
The utility model relates to and is used for the fixedly pipeline conversion of connection device swivelling pipe road direction, a kind of swivel joint with novel sealing structure of conveyance fluid.
Swivel joint is to be used for the fixedly engineering goods of pipeline conversion of connection device swivelling pipe road direction.Swivel joint one end is connected with rotation pipeline on the equipment, and an end joins with the pipeline of fixing accommodating fluid, has fluid to flow through in the pipeline.Compensatory, the sealability of swivel joint, verticity are directly connected to its working life.
Present known swivel joint is made up of housing, hollow shaft, graphite cylinder ring, sphere ring, spring.Sphere on the hollow shaft matches with the sphere ring, seals.After the wearing and tearing of sphere ring, spring promotes hollow shaft vertically near the sphere ring, the gap that compensate for wear causes.Graphite cylinder ring bearing hollow shaft rotates.The shortcoming of this kind structure is: spring is installed in the swivel joint enclosure interior, and spring is subjected to friction and hot fluid heating back distortion, and compensation ability descends, and causes leakage; The graphite cylinder ring is a sliding bearing, and is easy to wear, and the impurity in the fluid of wearing and tearing back enters the graphite cylinder ring, rotates dumb; After the wearing and tearing of graphite cylinder ring, the impurity in the fluid very easily enters the ball face sealing end face, damages seal face, causes swivel joint to scrap because of leakage.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of have novel sealing structure, good seal performance, long service life are provided; The swivel joint that volume is little.
The purpose of this utility model is achieved in that
The utility model adopts O-ring seals and the combined novel radial compliance sealing configuration of oil sealing, and the principle of this kind sealing configuration is to utilize the elasticity of Sealing self to compensate, and has guaranteed the swivel joint good seal, is difficult for revealing; Use rolling bearing and replace sliding bearing graphite cylinder ring, the rotation flexibility and reliability, it is little to wear and tear; Do not have spheric structure on the hollow shaft, volume is little, and the housing volume is also dwindled, and swivel joint is in light weight.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is the sectional drawing according to the swivel joint that the utility model proposes.
Describe the details and the working condition of the concrete structure that proposes according to the utility model swivel joint in detail below in conjunction with accompanying drawing.
1. hollow shafts among the figure, 2. rolling bearing assembly, 3.O shape seal ring, 4. oil sealing, 5. housing.
The utility model is equipped with O-ring seals (3) and oil sealing (4) between hollow shaft (1) and housing (5), the combined radial compliance sealing of this kind O-ring seals (3) and oil sealing (4) utilizes the elasticity of Sealing self to compensate, guaranteed the swivel joint good seal, easy to leak can not improve 6 times working life; Between hollow shaft (1) and housing (5) rolling bearing assembly (2) is housed, makes swivel joint pivoting friction coefficient little, it is little to wear and tear, and rotates flexibility and reliability; The utility model hollow shaft outer surface does not have sphere, and volume can be littler by 1/3rd with the flow swivel joint than existing.
Claims (2)
1. one kind has novel sealing structure and is used for the fixedly pipeline conversion of connection device swivelling pipe road direction, and the swivel joint of conveyance fluid is made up of hollow shaft, rolling bearing assembly, O-ring seals, oil sealing, housing.It is characterized in that having O-ring seals and the combined radial compliance sealing of oil sealing; Rolling bearing assembly is installed.
2. have the novel sealing structure swivel joint and it is characterized in that being equipped with the thrust ball bearing assembly according to right 1 is described.
