Abstract
The invention discloses a high-pressure high-speed rotary joint, which comprises a stator (1) and a rotor (2), wherein the two ends of the stator (1) are provided with end covers (3), and the inner sides of the end covers (3) are provided with O-shaped rings (5); the rotor (2) is connected with the stator (1) through a bearing (4); the stator (1) is radially provided with an operating oil hole (8) and an oil drain hole (9); an outer circumference of the rotor (2) is provided with a servo ring (7), and a Y-shaped sealing ring (6) is arranged between the servo ring (7) and the stator (1). The outer circumference of the rotor in the high-pressure high-speed rotary joint is provided with the servo ring, and the Y-shaped sealing ring is arranged between the servo ring and the stator, thus the cooperation of both and the self-adjustment of the Y-shaped sealing ring make the combination of the stator and the rotor tighter and more reasonable; when the operating pressure cannot meet the operation requirement, the rotary joint can be continuously operated only by replacing the servo ring, thus the maintenance and repair are convenient and the service life of parts is prolonged.
Description
Technical field
The invention belongs to the seal arrangement technical field, particularly a kind of high pressure high speed rotating joint.
Background technique
To be flowing medium (oil, steam, water, gas etc.) be input to connection sealed member the place apparatus from static pipeline with swivel joint, is the seal arrangement that solves run, drip, leak, energy saving, protection environment.The swivel joint housing of normally used high pressure (GYL type) series mainly adopts overall structure, in whole housing outer tube is installed, pipe in installing in the outer tube, and outer tube is supported by front and back bearings, on the interior pipe seal ring is housed.The swivel joint of this kind structure is when rotating operation, and latus rectum and pressure are subjected to restriction to a certain degree, and Sealing leakage easy to wear, so working life is very short, does not satisfy the needs of long-term use.
Summary of the invention
The high pressure high speed rotating joint that the invention provides a kind of long service life, good sealing effect, maintains easily and repair.
A kind of high pressure high speed rotating joint, comprise stator and rotor, the two ends of described stator are provided with end cap, the inboard of end cap is provided with O type ring, rotor is connected on the stator by bearing, described stator radially is provided with work oilhole and draining hole, and described rotor excircle is provided with servo loop, is provided with y-type seal ring between described servo loop and the stator.
Seal clearance a between described rotor and the servo loop

Be provided with the nano silicon carbide silicon layer with the servo loop contact position on the described rotor.
Described servo loop internal surface and rotor contact position are provided with nanometer graphite layer.
Because high pressure high speed rotating joint rotor excircle of the present invention is provided with servo loop, be provided with y-type seal ring between described servo loop and the stator, the self-control of both cooperations and y-type seal ring, make stator and combining of rotor more tight with rationally, the constant clearance between rotor and the servo loop and the parameter of swivel joint adapt, be easy to guarantee that cooperation between the two is in the optimum state, durable for a long time; The servo loop self-aligning that is provided with on the rotor excircle, under the situation that working pressure constantly changes, seal clearance still remains unchanged, and coaxality is become better and better with the pressure increase in the design pressure scope; Be provided with ' film bearing ' effect that the nanometer graphite layer that is provided with on nano silicon carbide silicon layer and the described servo loop internal surface with matching can be realized the anti-attrition selflubricating with the servo loop contact position on the described rotor, and both " locking " phenomenons can not appear, when working pressure can not satisfy job requirement, only needing to change servo loop just can work on, be convenient to safeguard and maintenance, prolong the working life of part, reduced cost.Description of drawings
Below in conjunction with accompanying drawing high pressure high speed rotating joint of the present invention is described further:
Fig. 1 is the structural representation of high pressure high speed rotating joint of the present invention;
Fig. 2 is the structural representation of high pressure high speed rotating joint rotor of the present invention and servo loop.
Embodiment
As shown in Figure 1, a kind of high pressure high speed rotating joint, comprise stator 1 and rotor 2, the two ends of described stator 1 are provided with end cap 3, the inboard of end cap 3 is provided with O type ring 5, and rotor 2 is connected on the stator 1 by bearing 4, and described stator 1 radially is provided with work oilhole 8 and draining hole 9, described rotor 2 excircles are provided with servo loop 7, are provided with y-type seal ring 6 between described servo loop 7 and the stator 1.
