Liquid storage tank on described upper shell comprises 1 major trough and minute is located at 2 secondary grooves of major trough both sides, wherein major trough with liquid entering hole over against being communicated with; Corresponding on described lower shell body 3 liquid storage tanks are set, wherein the liquid storage tank of both sides with liquid return hole over against being communicated with.
Described upper shell and lower shell body are provided with 4 seal grooves, and outermost 2 seal grooves are in the outside of liquid return hole, thereby the fine seal action that plays prevents that liquid from flowing out from the two ends of axle sleeve.
Described seal ring comprises two single ring architectures and clamp, and described single ring architecture is surrounded by the splicing of multistage carbocyclic ring lobe, the voussoir splicing that the stitching portion of adjacent two sections of carbocyclic ring lobes is coupling, and end gap is left in stitching portion; The external diameter of described monocycle also overlaps spring; Two single ring architectures are respectively equipped with draw-in groove, and described clamp is located in draw-in groove and two single ring architectures are connected and fixed side by side.
The two ends of described carbocyclic ring lobe are arc-shaped joint.
End gap on described two single ring architectures is for shifting to install.
Also comprise base, described lower shell body is fixedly mounted on base.
Beneficial effect: with respect to prior art, the utlity model has simple in structure, space hold is little, be convenient to the advantages such as dismounting, realizes medium from meront to a rotating body conversion process.For major diameter axle or axle is not quick detachable and pressure is larger occasion, be specially adapted to the occasion of center driving Tube Mill tail water spray.
In the utility model, seal ring is by whole carbocyclic ring is cut into multistage in addition, and the joint of every section of carbocyclic ring lobe is arc-shaped joint, and between two sections of carbocyclic ring lobes, closely, and joint is not fragile in transportation process in contact.Install simple, cost-saving, seal ring is installed rear every two sections of joints and is left certain end gap, make carbocyclic ring after wearing and tearing, adjacent each section of carbocyclic ring do not interfere with each other and axle or axle sleeve are pressed close in radially inside slippage, keep rational matching gap between carbocyclic ring and axle or axle sleeve, the twice monocycle joint end gap of last twin nuclei, not on same straight line, makes sealing effect better.When seal failure, only need to change seal ring, it is convenient to change.

Embodiment
Below in conjunction with accompanying drawing and with specific embodiment, further illustrate the utility model.Should understand these embodiments and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figures 1 to 3, a kind of major diameter swivel joint, comprises rotating shaft, axle sleeve, upper shell, lower shell body and seal ring, and described axle sleeve is provided with the passage that is communicated with cylinder and end face, and the outside that is fixed on rotating shaft rotates with rotating shaft; Described lower shell body is located at axle sleeve bottom, what described upper shell was corresponding is located at axle sleeve top and is connected with lower shell body, described upper shell be provided with axle sleeve on the liquid entering hole of passage cylinder open communication, corresponding liquid storage tank and the seal groove of being also provided with on the surface of contact of described upper shell and lower shell body and axle sleeve, described seal groove is provided with seal ring, and described lower shell body is also provided with the liquid return hole being communicated with liquid storage tank.Liquid flows into the major trough in housing from the liquid entering hole of housing, then flows out by the passage in groove.The pressure of liquid is not less than 0.2MPa, thereby can guarantee to have enough liquid to flow into back flash through seal ring, forms infiltration sealing.Wherein, the liquid storage tank on upper shell comprises 1 major trough and minute is located at 2 secondary grooves of major trough both sides, wherein major trough with liquid entering hole over against being communicated with; Corresponding on described lower shell body 3 liquid storage tanks are set, wherein the liquid storage tank of both sides with liquid return hole over against being communicated with
Wherein, seal groove is She Si road at least, and it is first sealing configuration that twice are located between major trough and liquid return trough, and it is second sealing configuration that another twice are located between liquid return trough and the external world.Housing and base are fixed, and axle sleeve is followed axle and rotated together, and the gap of housing and axle sleeve is sealed by two graphite-seal rings.Housing, axle sleeve and two graphite-seal ring form sealing configuration, and medium is entered by import, then is flowed out by the side exit of axle sleeve.
The utility model lower shell body is provided with liquid return trough, and when first sealing configuration has leakage, the medium of leakage flows in liquid return trough, then is flowed out or be connected in medium container by liquid return hole.Second sealing configuration (being outermost two sealing configurations) has guaranteed that liquid can not leak along both sides.Liquid enters into major trough 3 from import 2 and then by the outlet 6 of axle sleeve, is flowed out.A small amount of liquid flow in liquid return trough 11 through seal ring, through liquid return hole 10, flows out.Second seal ring 7 can prevent that the water in liquid return trough from flowing out along axle sleeve 1 both sides.
Sealing configuration of the present utility model has adopted a kind of two graphite-seal rings of self-compensation type.First, seal ring adopts spells loop type, and each spells ring two ends has joint and other spelling ring to be connected.Outside is provided with groove, and spring is close to axle sleeve by groove by spelling ring.So just can realize the installation of major diameter turning surface.Every circle seal ring has at least on a piece and has draw-in groove.One section of insertion draw-in groove of clamp, the other end inserts housing fixes seal ring.Gap is left in the joint of every two pieces in addition.After graphite annulus and axle sleeve friction generation wearing and tearing, seal ring continues to be close to axle sleeve and can not produce gap with axle sleeve owing to spelling the mutual jack-up of ring under the effect of spring.Twice specification is identical but packing ring combination that interstitial site staggers is used.To be sealed long-time use after inefficacy, only need take housing apart, changes seal ring.Arranging of seal ring can multilayer, many covers are used to reach better sealing effect.The spelling number of rings amount of seal ring can be 4 sections, also can be 3 sections or more.Draw-in groove also can be as requested at a place or many places arrange.
