Abstract
A modified rotary joint comprises a casing, a rotary outer tube, an inner tube, an elbow, a bottom cover, an oil-free bearing, a spherical seal ring and a spring, wherein the rotary outer tube is positioned in the casing, one end of the rotary outer tube extends out of the casing, the inner tube is contained in the rotary outer tube, the elbow and the bottom cover are installed at two ends of the casing respectively, the oil-free bearing and the spherical seal ring are positioned in the casing, the oil-free bearing installed on the rotary outer tube is capable of leading the rotary outer tube to rotate, the spherical seal ring is abutted against the rotary outer tube, and one end of the spring is abutted against the casing while the other end is abutted against the oil-free bearing, so that the spherical seal ring is abutted against the surface of the rotary outer tube. The rotary joint has the advantages of simple structure, smaller size, better sealing performance and the like.
Description
Technical field
The utility model relates to a kind of rotating machinery, is specifically related to a kind of modified model swivel joint, belongs to mechanical spare part technical field.
Background technique
Swivel joint is used for the part that rotates is carried liquid medium.Existing swivel joint mainly comprises a moving joint and a quiet joint, is connected with interior pipe in described quiet joint and the moving joint, and quiet joint and moving joint are installed in respectively on the fixed pedestal of equipment and the rotating part that the relative fixed pedestal rotates.
Yet, because the moving joint and the coaxality between the quiet joint of above-mentioned swivel joint are relatively poor, cause the fitting surface serious wear between moving joint and the quiet joint, influence the sealability of swivel joint, thereby cause steam, oil or other dielectric leakages.
Therefore, for avoiding above-mentioned technical problem, the necessary rational more swivel joint of a kind of project organization that provides is to overcome described defective of the prior art.
The model utility content
The purpose of this utility model is to provide a kind of sealability modified model swivel joint preferably, addressing the above problem,
For achieving the above object, the technological scheme that the utility model is taked is: a kind of modified model swivel joint, it comprises: housing, the rotation outer tube body, interior pipe, elbow, bottom, oilless bearing and spherical seal ring, wherein, described rotation outer tube body is positioned at housing, and an end extends outside the housing, described in pipe be contained in the rotation outer tube body, described elbow and bottom are installed on the two ends of housing respectively, described oilless bearing and spherical seal ring are positioned at housing, and described oilless bearing is installed on the rotation outer tube body and makes the rotation of rotation outer tube physical efficiency, and described spherical seal ring is connected on the rotation outer tube body, described swivel joint further comprises a spring, described spring one end is resisted against on the housing, and the other end is resisted against on the oilless bearing, makes spherical seal ring be connected to rotation outer tube body surface.
Modified model swivel joint of the present utility model further is set to: described spring is a stage clip.
Modified model swivel joint of the present utility model further is set to: be provided with a sealing gasket between described bottom and the housing.
Modified model swivel joint of the present utility model also can be set to: described bottom by screw threaded on described housing.
Compared with prior art, the utlity model has following beneficial effect: when spherical seal ring or the wearing and tearing of rotation outer tube body, pressure by spring makes spherical seal ring closely contact with the rotation outer tube body, and can provide the rotation outer tube body lubricated, thereby alleviated friction and wear, prolonged the working life of product.
Description of drawings
Fig. 1 is the half sectional view of modified model swivel joint of the present utility model.
Embodiment
See also shown in Figure 1ly, the utility model is a kind of modified model swivel joint, and it is by housing 1, rotation outer tube body 2, and interior pipe 3, elbow 4, bottom 5, oilless bearing 6, spherical seal ring 7, members such as spring 8 and sealing gasket 9 are formed.Wherein, described rotation outer tube body 2 is positioned at housing 1, and an end extends outside the housing 1.Pipe 3 is contained in the rotation outer tube body 2 in described.Described elbow 4 and bottom 5 are installed on the two ends of housing 1 respectively.Described sealing gasket 9 is located between bottom 5 and the housing 1, prevents steam, oil or other dielectric leakages.Described bottom 5 is screwed together on the described housing 1 by bolt 10.Described oilless bearing 6 and spherical seal ring 7 lay respectively in the housing 1, and this oilless bearing 6 is installed on rotation outer tube body 2 can be rotated, and described spherical seal ring 7 is connected on the rotation outer tube body.Described spring 8 is specially a stage clip, and the one end is resisted against on the housing 1, and the other end is resisted against on the oilless bearing 6, further makes spherical seal ring 7 be connected to rotation outer tube body 2 surfaces.
The maximum improvement part of modified model swivel joint of the present utility model is: by spring 8 is set, thereby spherical seal ring 7 is closely contacted with rotation outer tube body 2, when spherical seal ring 7 wearing and tearing, pressure by spring 8 makes spherical seal ring 7 contact with rotation outer tube body 2, and can provide rotation outer tube body 2 lubricated, thereby alleviated friction and wear, prolonged the working life of product.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
