Description
Technical field
The present invention relates to liquid conducting pipes, the specifically connection set of pipeline, more specifically a kind of for liquid conducting pipes can high voltage bearing articulating device.
Background technique
In actual production and life application, liquid conducting pipes need to carry out necessary rotation in pipeline connection place sometimes, and one of them pipeline is fixed, and another pipeline rotates.Owing to there being liquid to exist in pipeline, at this moment just seem extremely important in the formedness of the sealing of the connection place of these two pipelines, particularly liquid is in pipeline by high-voltage transmission in the situation that, and guaranteeing that joint is not leaked just needs sealing reliably.General method is to seal with rubber pad, after rotating, between rubber pad and pipeline, has relative movement, easily produces gap, and liquid leakage occurs, and secondly, the long-term mill of rubber pad and pipeline can cause rubber pad to damage after examining, and does not have seal action.
Summary of the invention
In order to overcome the defect of prior art, the present invention adopts the mode of multi-layer structure very cleverly, design a kind of for liquid conducting pipes can high voltage bearing articulating device, keep rubber pad and pipeline to combine closely all the time, realize rubber pad and pipeline and do not produce relative movement, and guarantee not occur leak of liquid.
Of the present invention for liquid conducting pipes can high voltage bearing articulating device, comprise sealing gasket, its innovation is: comprise overall fixed cover, two sealing gaskets, two sealing gasket supports, spring ball assemblying body, described overall fixed cover is provided for the axial mounting hole of mounting spring ball set zoarium at its ring-type position, two sealing gasket supports are placed in respectively overall fixed cover upper and lower end, its setting for coordinating the ball grooves of ball towards overall fixed cover, two sealing gaskets are placed in respectively the outer end of two sealing gasket supports.
Described sealing gasket is ring-type sheet, is convenient to touch with tube wall and the good knot of sealing gasket support.Sealing gasket is made with flexible nonmetal material, and these materials comprise plastics and rubber-plastics material or other material of various rubber, various softnesses.
Described ball is spherical, makes with metallic material.Ball requires evenly regular, and it is high that hardness is wanted, and intensity will be got well, wear-resisting, therefore can use wear-resistant metal material or abrasion resistance alloy.
The pipeline that articulating device of the present invention connects can movablely rotate, and the pipeline at two can relatively rotate.Here can consider two kinds of modes: a kind of is that articulating device can only relatively rotate with the pipeline of, and another kind is that the pipeline at articulating device and two can relatively rotate.For rear a kind of mode, a kind of embodiment of the present invention is: the axial mounting hole of overall fixed cover is through hole, a ball of the each arrangement in its spring two of spring ball assemblying body.
For good, spring is combined with ball firmly, the present invention also arranges a ball rack being connected with spring, its ball of spring ball assemblying body is placed on the ball rack being connected with spring.
Spring ball assemblying body is arranged in the axial mounting hole of overall fixed cover, and spring ball assemblying body plays a part to support sealing gasket support, and holds out against the sealing gasket that is positioned at sealing gasket support outer end, makes it to combine closely all the time with pipeline.For sealing gasket support stability of rotation on ball, the quantity of spring ball assemblying body can not be very little.The axial mounting hole that makes overall fixed cover in the present invention is 3 ~ 12, and 2 of the minimum number of spring ball assemblying body are no more than at most the number of axial mounting hole.
Scheme is preferably: the axial mounting hole of overall fixed cover is 6 ~ 8, and the quantity of spring ball assemblying body equals the number of axial mounting hole.
The ball grooves of the sealing gasket support in the present invention is made with metallic material.As a kind of embodiment of the present invention, the present invention is the support fixed groove around whole outer shroud in the arranged outside of the outer shroud of the ball grooves of sealing gasket support also, and has in the outer shroud inner side of overall fixed cover the fixing pin that snaps in support fixed groove.In this scheme, the quantity of fixing pin is 3 ~ 8, taking 4 as good.Fixing pin, through the outer shroud of overall fixed cover, snaps in support fixed groove, and overall fixed cover is realized and being connected with sealing gasket support.The groove width of fixed groove is a bit larger tham fixing pin diameter, therefore sealing gasket support has the up and down leeway of little Xu, under the elastic force effect of spring ball assemblying body, sealing gasket support is held out against to duct orientation.
Device of the present invention can be realized and being connected of pipeline as bonding or welding by various technology.After being connected with pipeline, pipeline and sealing gasket and sealing gasket support also become the entirety that can not relatively rotate, and this entirety can relatively rotate with overall fixed cover.
Of the present invention for liquid conducting pipes can high voltage bearing articulating device, be the movement on ball by sealing gasket support, drive upper and lower two-part to relatively rotate.After being connected in pipeline, the pipeline of articulating device one end, sealing gasket and sealing gasket support become as a whole, can rotate with respect to overall fixed cover.If a ball has all respectively been settled at its spring two of spring ball assemblying body, the pipeline of the other end of articulating device, sealing gasket and sealing gasket support also become as a whole so, can rotate with respect to overall fixed cover.Can also find out thus, the mode that adopts two all to settle the spring ball assemblying body of ball, rotation will be convenient, and such mode is being subject to limited space or is in particular cases more adapting to, in the time that the pipeline of one end is not allowed rotation, can rotate easily the pipeline of the other end.
The present invention ensures that by spring sealing gasket and pipeline combine closely all the time, in the time that upper and lower two pipelines relatively rotate, ball rolls, the ball grooves of sealing gasket support moves, replaced the fricting movement of sealing gasket and pipeline in prior art with rolling motion between ball and ball grooves, because ball and ball grooves are all to make with metallic material, intensity is high, hardness is good, wear-resisting, and rolling friction is more much smaller than sliding friction, so articulating device of the present invention is not easy to produce wearing and tearing, be not easy to produce gap, and sealing gasket just keeps combining closely with pipeline, do not rub, therefore sealing gasket can not wear and tear, sealing gasket is brought into play good seal action, guarantee not occur leak of liquid.Sealed member and rotatable parts are independently, act in accordance with the division of their functions and duties, and are innovations of the present invention, are also the defects that the present invention overcomes prior art, realize the technical support of goal of the invention.
Articulating device of the present invention, stability of rotation, good airproof performance, wearing and tearing are few, and the life-span is long, can be used for various liquid conducting pipes, be particularly suitable for the pipeline of high-pressure delivery liquid, and be subject to limited space or in particular cases need the occasion of pipeline energy flexible rotating.
