Abstract
The utility model discloses an inserting structure combining a rotary joint and a transition ring. The inserting structure comprises a graphite ring, a spherical body and an anti-rotation pin, wherein the graphite ring is jointed with the spherical body; a sealing ring is arranged on an inward concave end surface of the spherical body; an anti-rotation pin groove is formed in the spherical body; and one end of the anti-rotation pin extends into the anti-rotation pin groove, and the other end of the anti-rotation pin is fixedly mounted on a rotor sealing ring. The inserting structure improves the processability and the assembly performance of the transition ring; the requirement on the processing precision of the surface of a metal sphere is not high, the graphite ring can adopt a segmented-splicing structure; the procurement cost and the procurement period of the graphite material are reduced and shortened, the maintenance is convenient, and the abrasion degree of a sealing part on the sphere is reduced.
Description
Technical field
The utility model relates to the mechanical sealing technology field, relates in particular to a kind of swivel joint transition ring combined type insert structure.
Background technique
Use of the swivel joint of mechanical seal structure has the sphere friction pair structure of more anti-vibration of degrees of freedom and swing more in the market.For adapting to the vibrations and the swing of field apparatus, it is sphere that transition ring adopts a side, and opposite side is the project organization on plane.When this structure can guarantee rotating shaft generation beat, transition ring can floating compensation, guaranteed the sealing effect of swivel joint.
Because transition ring is born axial pressure and tension force radially simultaneously when work.Therefore transition ring needs insert metal insert ring to increase the tensile strength of transition ring.
There are these some problems in this structure:
Because transition ring adopts wear-resisting and self-lubricating property preferably graphite material make that the tensile strength of transition ring is lower, must insert have the metal insert ring of enough tightening forces.
2. transition ring is participated in two friction pairs simultaneously, so insert ring both sides all need reserve enough working depths, with guarantor unit in the time swivel joint work well.This transition ring can only be scrapped when transition ring one lateral wearing is heavier.
3. two transition ring both sides friction pairs are difficult to realize the role-taking of its main seal action in the swivel joint operation process.Often find ball face sealing surface wear serious situation.
The model utility content
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of swivel joint transition ring combined type insert structure is provided.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of swivel joint transition ring combined type insert structure; Comprise graphite annulus, spherical surface body and stop pin; Described graphite annulus and spherical surface body fit, and the indent end face of said spherical surface body is provided with seal ring, and described spherical surface body is provided with the anti-rotation cotter way; One end of said stop pin extend in the anti-rotation cotter way, and the other end is fixedly mounted on the rotary piston sealing ring.
Described graphite annulus is the distinguish splicing construction.
Described graphite annulus is stitched together through graphite insert ring.
Be filled with teflon in the described seal ring.
The utility model has improved the processability and the assembling of transition ring; Metal sphere surface Machining precision need not be too high, and graphite annulus can adopt the distinguish splicing construction, reduced the purchase cost and the procurement cycle of graphite material; Be convenient to maintenance, reduce the degree of wear of ball face sealing parts.
Description of drawings
Fig. 1 is the existing technology schematic representation;
Fig. 2 is the utility model schematic representation.
Wherein: 1, graphite annulus 2, graphite insert ring 3, spherical surface body 4, anti-rotation cotter way 5, stop pin 6, seal ring 7, rotary piston sealing ring.
Embodiment
As shown in Figure 2; A kind of swivel joint transition ring combined type insert structure; It is characterized in that: comprise graphite annulus 1, spherical surface body 3 and stop pin 5; Described graphite annulus 1 fits with spherical surface body 3, and the indent end face of said spherical surface body 3 is provided with seal ring 6, is filled with teflon in the described seal ring 6; Described spherical surface body 3 is provided with anti-rotation cotter way 4, and an end of said stop pin 5 extend in the anti-rotation cotter way 4, and the other end is fixedly mounted on the rotary piston sealing ring 7; Said spherical surface body 3 fits with rotary piston sealing ring 7; Described graphite annulus 1 is the distinguish splicing construction, and described graphite annulus 1 is stitched together through graphite insert ring 2.
The plane sealing friction pair adopts self lubricity graphite material preferably, when mainly accomplishing the swivel joint running, seals in relative rotation between running shaft and housing, realizes the radial floating of transition ring simultaneously; The sphere friction pair material adopts plasticity teflon seal ring preferably, seal action when mainly realizing the swivel joint swing; 1 of graphite annulus bears pressure and does not bear tension force radially; Spherical surface body 3 increases rotation prevention structure assurance sphere friction pair and only bears the seal action of swivel joint, and does not participate in sealing in relative rotation between running shaft and housing.
