Description
Technical field
The utility model relates to joint mechanism, particularly relates to a kind of high temp. rotary joint.
Background technique
In groove type solar field, heat collecting pipe sways in process and requires that the pipeline be connected with heat collecting pipe realizes rotating, and in slot type heat collecting pipe, conduction oil or temperature of molten salt are very high more than 400 DEG C, this requires that the swivel joint installed can bear high temperature, and certain pump pressure.High temp. rotary joint is in the prior art mainly reflected at a high speed, and under middle temperature environment, and the rotating mechanism required in groove type solar field is relatively slower, and shines upon synchronous, the structure therefore required has very large difference.In groove type solar place is built, occupation area of equipment is wide, and cost of investment is huge, and the cost of each component and mechanism reduces to have photo-thermal solar energy better to be promoted and development.Therefore, need a kind of structure simple, with low cost, practical swivel joint.
Model utility content
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of high temp. rotary joint, comprise left ell, right ell, steel ball, annulus, slip ring, spring, annulated column, it is characterized in that, described left ell is enclosed within right ell, described annulus is placed on the two ends of annulated column, described annulated column also comprises through hole and annular groove spring and to be placed in annulated column and to apply pretightening force to annulus, described steel ball is placed between two pipe interfaces, two ells rotate at axial direction, described slip ring is placed on right ell one end, and contact with annulus, in rotational action, there is sliding friction.
Further, described left ell is being provided with a slip ring near right angle, the interface of left ell and right ell is respectively provided with two semi-circular recesses, and with steel ball Spielpassung, it is stepped on the right-hand member pipe end of left ell is, stepped on right angle caliber is at right ell, with the right-hand member pipe end Spielpassung of left ell.
Further, described slip ring structure is ring plate, and one side is provided with annular groove, and one side is plane, and annular groove coordinates with annulus, is sliding friction in rotation.
Further, described annulated column is at the some through holes of radial equipartition, and annulated column end face is provided with annular groove, hole put into by spring, and the natural length of spring is longer than annulated column, when right ell puts into left ell inside, by slip ring extruding annulus until annulus contacts with annulated column.
The good effect that the utility model has is:
It is complicated that the utility model order solves existing swivel joint mechanism design, and high temperature resistant condition is poor, and need the problems such as often maintenance.Have structure simple, easy to loading and unloading, two right-angle type structure decreases unnecessary jointing.The fluid temperature circulated in swivel joint is more than 400 degrees Celsius, and structure is simple, and the impact that its high temperature produces is less, and its sealing configuration is sliding metallic friction sealing.

Embodiment
In order to make the utility model object, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is a kind of high temp. rotary joint structural representation of the present utility model.
A kind of high temp. rotary joint, comprise left ell 1, right ell 2, steel ball 3, annulus 4, slip ring 5, spring 6, annulated column 7, it is characterized in that, described left ell 1 is enclosed within right ell 2, described annulus 4 is placed on the two ends of annulated column 7, described annulated column 7 also comprises through hole 701 and annular groove 702, spring 6 to be placed in annulated column 7 and to apply pretightening force to annulus 4, described steel ball 3 is placed between two pipe interfaces, two ells rotate at axial direction, described slip ring 5 is placed on right ell 2 one end, and contacts with annulus 4, in rotational action, have sliding friction.
Wherein, left ell 1 is being provided with a slip ring 5 near right angle, left ell 1 with the interface of right ell 2 are respectively provided with two semi-circular recesses, and with steel ball 3 Spielpassung, it is stepped on the right-hand member pipe end of left ell 1 is, stepped on right angle caliber is at right ell 2, with the right-hand member pipe end Spielpassung of left ell 1.
Wherein, slip ring 5 structure is ring plate, and one side is provided with annular groove, and one side is plane, and annular groove coordinates with annulus 4, is sliding friction in rotation.
Wherein, annulated column 7 is at the some through holes of radial equipartition, and annulated column 7 end face is provided with annular groove 702, through hole 701 put into by spring 6, and the natural length of spring 6 is longer than annulated column 7, when right ell 2 puts into left ell 1 inside, extrude annulus 4 until annulus 4 contacts with annulated column 7 by slip ring 5.
During assembling, first an annulus 4 put into left ell 1 and contact with the annular groove on its slip ring 5, then, put into annulated column 7, annulated column 7 is placed with spring 6 in advance, again an annulus 4 is put into, contact with the spring 6 in annulated column 7, subsequently the one side of slip ring 5 with annular groove is put into, and contact with annulus 4, subsequently right ell 2 and steel ball 3 are put into left ell 1, mounting type is as the assembling mode of bearing.After installing, the horizontal pipe end extruding slip ring 5 of right ell 2, make annulus 4 and spring 6 stressed, level annulus 4 contacts with slip ring 5, and there is certain pressure, spring 6 forced compression, annulus 4 contacts with the annular groove on annulated column 7, surface of contact all has sliding friction, and have certain pressure make liquid be unlikely to reveal.
In assembly structure, the effect of part slip ring 5 and parts annulated column 7 is the rotary inertias in order to increase ell, and the pretightening force that spring 6 provides makes slip ring 5 and annulated column 7 keep geo-stationary, to reduce frictional loss amount.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
