Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment
The embodiment of the present invention provides a kind of swivel joint, as depicted in figs. 1 and 2, the rotating ring 3 that this swivel joint comprises stationary ring 1 and is inserted in stationary ring 1, Sealing 7 is provided with between stationary ring 1 and rotating ring 3, rotating ring 3 is arcuate structure with the surface of contact of Sealing 7 or the surface of contact of Sealing 7 and stationary ring 1, and stationary ring 3 is spliced by stationary ring body 3a and end cap 3b vertically.Wherein, the external frame of stationary ring 1 can be cuboid can be also hollow cylindrical body, according to the outer contour shape of the PRODUCTION STATUS determination stationary ring 1 of reality.The anchor ring that rotating ring 3 can provide along stationary ring 1 rotates, and the rotation that end cap 3b and Sealing 7 are rotating ring 3 provides rotation space, makes rotating ring 3 can have larger the sphere of activities on anchor ring, further increases the eccentric angle α of swivel joint.Wherein, Sealing 7 can adopt PTFE+C25 material, when installing Sealing 7, the seal 7 being arranged in rotating ring 3 outer surface and together sending in stationary ring 1, the seal 7 can being stuck in the first groove 6, then being covered by end cap 3b.In addition, the stationary ring passage 2 be connected and the rotating ring passage 4 be connected with rotating ring 3 are respectively arranged with flange, and this flange can match with stationary ring 1 with the flange on petroleum pipeline, and realize being tightly connected.
Alternatively, the outer surface of the plug-in mounting end of rotating ring 3 is cambered surface, and the internal surface of Sealing 7 matches with described cambered surface, and Sealing 7 location and installation is on stationary ring 1.Wherein, outwardly the giving prominence to of plug-in mounting end of rotating ring 3.Certainly, in actual production with in using, also the internal surface of stationary ring 1 can be designed to cambered surface, accordingly, the outer surface of Sealing 7 matches with this cambered surface, and Sealing 7 location and installation is on rotating ring 3.
Particularly, the internal surface of stationary ring 1 is provided with the first groove 6 for installing Sealing 7, and Sealing 7 location and installation is in the first groove 6.The groove shapes of this first groove 6 matches with the external frame of Sealing 7, and Sealing 7 can be stuck in the first groove 6.
Particularly, the splicing surface of stationary ring body 3a and end cap 3b is positioned at the first groove 6 place.
Further, the plug-in mounting end of rotating ring 3 is provided with boss 10.Flow in the process of rotating ring 3 at medium by stationary ring 1, this medium can flow through on the end face of boss 10, and applies a pressure to the end face of this boss 10, and this pressure makes rotating ring 3 can be pressed on closely on Sealing 7.When the pressure of medium is larger, what extrude between this rotating ring 3 and Sealing 7 is tightr, and therefore, swivel joint provided by the invention can be applicable on the larger device of pressure medium.
In conjunction with above-mentioned mode of execution, in another kind of mode of execution of the present utility model, stationary ring 1 internal surface is provided with the liftout mechanism for outwards being ejected by rotating ring 3, and this liftout mechanism by rotating ring 3 closely by being pressed on Sealing 7, can guarantee the sealing of this swivel joint further.
Alternatively, liftout mechanism comprises the position that spring 8 and the second groove 11, second groove 11 are arranged on corresponding rotating ring 3 plug-in mounting end on stationary ring 1 internal surface, and spring 8 one end is arranged in the second groove 11, and the outer surface of spring 8 the other end and rotating ring 3 offsets.Wherein, this spring 8 can be cylindrical spring or disc spring, this spring 8 can extrude rotating ring 3, rotating ring 3 and Sealing 7 is made to keep contacting closely, in addition, when the medium in swivel joint is nonconducting medium, electrostatic may be produced in the process of media flow, and may cause because delivery line vibrates the situation producing electric discharge between rotating ring 3 and stationary ring 2 because there is gap, if this medium is inflammable explosive article, then probably can cause danger, stationary ring 1 can be communicated with rotating ring 3 by the spring 8 that the embodiment of the present invention provides, thus avoid and there is electrostatic and cause dangerous problem.
Alternatively, the axis elongation line of spring 8 is through the center of circle of cambered surface.Prevent spring 8 from producing on rotating ring 3 surface the surface that unnecessary friction scratches rotating ring 3.
Alternatively, liftout mechanism is at least one, and liftout mechanism is evenly arranged along the circumferencial direction of stationary ring 1.The elastic force that stationary ring 1 can be made to be subject to spring 8 is like this evenly arranged.
Alternatively, end cap 3b is fixedly connected with stationary ring body 3a by bolt 5.
Swivel joint provided by the invention, rotating ring is made sphere structure, enable rotating ring in the inner rotation of stationary ring, for long petroleum pipeline, then can ensure the larger petroleum pipeline degree of eccentricity, avoid the clamping stagnation of swivel joint or rotate not smooth problem, simultaneously, swivel joint provided by the invention is provided with boss on rotating ring, is attached to closely on Sealing by rotating ring, ensures good sealing effect by the active force of medium.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
