Abstract
The utility model discloses a small-scale high-pressure rotary joint, which comprises a fixed body; the fixed body is connected with a high-pressure oil pump; a rotary body is covered and arranged on the fixed body which is connected with a high-pressure oil tube. An oil channel inside the fixed body is communicated with an oil channel inside the rotary body through a radial hole; a rotary sealing ring is arranged on the connection position between the fixed body and the rotary body. The utility model has the advantages of rational structure and stronger pressure-enduring ability; the contact between the fixed body and the rotary body is not easy to be worn and torn. The utility model has longer life time.
Description
Technical field:
The utility model relates to a kind of swivel joint.
Background technique:
Existing chicksan, easy to wear a little less than the voltage endurance capability, working life is short.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the minitype high voltage swivel joint that voltage endurance capability is strong.
Technical solution of the present utility model is:
A kind of minitype high voltage swivel joint, it is characterized in that: comprise the fixed body that is connected with high pressure oil pump, the solid of rotation that suit is connected with high-pressure oil pipe on the fixed body, the fixed body internal oil channel communicates with a rotating body oil duct by radial hole, and fixed body and solid of rotation connection part are provided with rotating seal ring.
Fixation postures is in the position of solid of rotation both sides, and tapered, the axial buffer rubber ring that dress contacts with fixed body on the conical surface, the conical surface arranged outside prevents the axially movable block body of axial buffer rubber ring.
The block body of fixed body tail end and fixed body are separate form, and the arranged outside of this block body has the axially movable back-up ring of anti-backstop.
The utility model is rational in infrastructure, and voltage endurance capability is strong, and fixed body and solid of rotation contacting point are not easy to wear, long service life.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of minitype high voltage swivel joint, comprise the fixed body 1 that is connected with high pressure oil pump, the solid of rotation 4 that suit is connected with high-pressure oil pipe on the fixed body 1, fixed body 1 internal oil channel communicates with a rotating body oil duct by radial hole 9, fixed body 1 is provided with rotating seal ring 3,5 with solid of rotation 4 connection parts, fixed body 1 is positioned at the position of solid of rotation both sides, tapered, the axial buffer rubber ring 2,8 that dress contacts with fixed body on the conical surface, the conical surface arranged outside prevents the axially movable block body 7,10 of axial buffer rubber ring.The block body 7 and the fixed body 1 of fixed body tail end are separate form, and the arranged outside of this block body 7 has the axially movable back-up ring 6 of anti-backstop.Block body 10 is the one form with fixed body.
