Abstract
The invention discloses a transition ring for a rotary joint. The transition ring comprises a graphite ring and a spherical face body; the graphite ring and the spherical face body are fixedly jointed together; and a sealing ring is arranged on an inner concave end surface of the spherical face body. The transition ring for the rotary joint has the advantages that abrasion caused to the graphite ring by an embedded ring can be eliminated effectively during the operation process; smooth operation of the transition ring can be ensured; the processability and the assemblability of the transition ring are improved; and the requirements on the surface machining accuracy of a metal spherical face are not very high, and the graphite ring can adopt a segmented splicing structure, so that the procurement cost and the procurement period of graphite material can be reduced, and the maintenance is convenient.
Description
Technical field
The present invention relates to the mechanical sealing technology field, relate in particular to a kind of swivel joint transition ring.
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.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of swivel joint transition ring is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of swivel joint transition ring, comprise graphite annulus and spherical surface body, and described graphite annulus and spherical surface body fixedly fit together, and the indent end face of said spherical surface body is provided with seal ring.
Described graphite annulus is the distinguish splicing construction.
Described graphite annulus is stitched together through graphite insert ring.
Described graphite annulus and spherical surface body fixedly fit together through the insert ring.
Be filled with teflon in the described seal ring.
The present invention can effectively eliminate the wearing and tearing of insert ring to graphite annulus in the equipment operation process; Guarantee the smooth running of transition ring; 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; Reduce the purchase cost and the procurement cycle of graphite material, be convenient to maintenance.
Description of drawings
Fig. 1 is the existing technology schematic representation;
Fig. 2 is a schematic representation of the present invention.
Wherein: 1, graphite annulus 2, graphite insert ring 3, insert ring 4, spherical surface body 5, seal ring 6, rotary piston sealing ring.
Embodiment
As shown in Figure 2; A kind of swivel joint transition ring comprises graphite annulus 1 and spherical surface body 4, and described graphite annulus 1 fixedly fits together through insert ring 3 with spherical surface body 4; The indent end face of said spherical surface body 4 is provided with seal ring 5, is filled with teflon in the described seal ring 5; Said spherical surface body 4 fits with rotary piston sealing ring 6; 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.
