Abstract
The utility model relates to a multichannel fluid rotary joint which is provided with a plurality of overlapping multichannel rotatable joint and used for fluid medium pipelines of the single point mooring system of shipping. The multichannel fluid rotary joint is characterized by being provided with two or more fixed overlapping inner rings. Each of the inner rings is provided with an corresponding outer ring outside, and a rotational support is arranged between each inner ring and each corresponding outer ring. A sealing ring is arranged between each inner ring and each corresponding outer ring to guarantee the sealing performance, each inner ring comprises an inner ring groove and an inner ring fluid via hole, and each outer ring comprises an outer ring groove and an outer ring fluid via hole. Each inner ring connecting pipe is arranged inside each corresponding inner ring and communicates with the inner ring fluid via hole, each outer ring connecting pipe is arranged outside each corresponding outer ring and communicates with the outer ring fluid via hole.
Description
Technical field
The present invention relates to a kind of swivel joint, have the rotatable joint of a plurality of runners that overlap, be used for boats and ships single point mooring system fluid medium delivery pipe.
Background technique
Single point mooring is a kind of new ship mooring mode, this single point mooring is because the mooring that does not need to rely on harbour just can realize boats and ships and to the loading and unloading of boats and ships, the particularly loading and unloading of liquid medium, can be in the zone that does not have large pier, open area particularly, not only can realize ship loading and unloading to large ship, and can realize loading and unloading to a plurality of boats and ships simultaneously.But because the boats and ships of single point mooring are in the mooring zone, boats and ships are subject to current and Wind effect, will do the 360 degree rotation motions of weathercock effect, and this motion will cause damage to the pipeline of loading and unloading liquid medium.
In recent years, a kind of Single-channel Rolling joint occurred, be used at single point mooring's state to boats and ships supply fuel oil and water, and can load and unload liquid Loaded goods.But this Single-channel Rolling joint makes the supply of multiple fluid medium or loading and unloading utilize same pipeline, causes the mutual pollution of various flowing mediums; When using two or more Single-channel Rolling joint, be arranged in parallel owing to connect the pipeline of boats and ships and swivel joint, the weathercock effect 360 of doing of boats and ships is spent rotation motions, will make these pipelines mutually twine and damage.
Summary of the invention
The object of the present invention is to provide a kind of multi-channel fluid swivel joint, can overcome the defective of prior art, load simultaneously and/or unload the multiple fluid medium.
In the present invention, the multi-channel fluid swivel joint has two or more overlapping interior rings that is fixedly installed, and encircles the outside in each and has a corresponding outer shroud, and encircle the rotary support between the corresponding outer shroud in encircling and being somebody's turn to do in each.
In the present invention, ring has an inner groove and an interior circulation body through hole in each, and this outer shroud has an outer groove and an outer shroud fluid through-hole.
In the present invention, in each, encircle and be somebody's turn to do interior the ring between the corresponding outer shroud and have sealing.
In the present invention, in each ring and should in rotary support between the corresponding outer shroud of ring, can be arranged on the ball bearing between the ring and this outer shroud in this, also can be roller bearing.
In the present invention, in each ring and should in rotary support between the corresponding outer shroud of ring, can be arranged on the thrust bearing of ring and this outer shroud end face in this.
In the present invention, encircling the sealing between the corresponding outer shroud in encircling and being somebody's turn to do in each, can be seal ring, also can be back-shaped sealing.
When installment state, it is inboard that the ring connecting tube is installed in corresponding interior ring in each, and be connected with interior circulation body through hole, inner groove is corresponding with outer groove, form the annular fluid passage of swivel joint inside, the outer shroud connecting tube is installed in the corresponding outer shroud outside, and is connected with the outer shroud fluid through-hole.
When the state of use, a plurality of pipelines on the boats and ships are connected with a plurality of outer shroud connecting tubes respectively, each outer shroud connecting tube is by outer shroud fluid through-hole, annular fluid passage and interior circulation body through hole, be communicated with interior ring connecting tube, the pipeline that the connection of interior ring connecting tube links to each other with harbour or base, thus formation harbour or base are connected with the pipeline of boats and ships.Under this state, the rotation motion of boats and ships drives respectively corresponding outer shroud by a plurality of pipelines and rotates, and has guaranteed that pipeline does not twine mutually, thereby has guaranteed that harbour or base are connected with the pipeline of boats and ships.
Concrete and other features of the present invention will further specify by embodiment, and the following examples are used for the present invention is described, but the invention is not restricted to the following examples.
