Embodiment
Further detailed description is done to the embodiment of the present invention below in conjunction with the accompanying drawings.
Four mouthfuls of distributing T-pipe mechanisms of a kind of nested type provided by the invention, it is overall as shown in figure 1, the mechanism includes compressing spiral shell
Mother 3 and connector 4.Upper nipple 4b and sidepiece nipple 4f wherein in connector 4 connects the first inner flexible tube 2 and second respectively
Inner flexible tube 5, upper coupling 4a and lower coupling 4k in connector 4 connect the first outer flexible tube 1 and the second outer flexible tube 6 respectively.
Described clamp nut, it is characterised in that annulus is hollow to allow the first outer flexible tube 1 to pass through, and its lower end interface is set
Conical internal thread matches with the external screw thread 4d of connector 4.
As a kind of preferred scheme, connector 4, upper coupling 4a, upper nipple 4b, external screw thread 4d, sidepiece nipple 4f,
Sidepiece return ring 4g, middle through hole 4i, lower coupling 4k are to be processed to cast by whole block material, then in upper nipple 4b, sidepiece
Anticreep snap ring is assembled at joint 4f and lower coupling 4k respectively and return ring forms.
The first thinner inner flexible tube 2 is fixed by upper nipple 4b and sidepiece nipple 4f respectively, passes through upper anticreep snap ring
4c and the spacing anticreeps of sidepiece anticreep snap ring 4h, and further improve sealing.Fluid in first inner flexible tube 2 is in inner via hole 4e
Migration flowing.Wherein, inner via hole 4e position is in the centre of upper nipple 4b cylinders, is an aperture run through, as interior
The flow channel of flexible pipe.
Upper anticreep snap ring 4c, sidepiece anticreep snap ring 4h and lower return ring the snap ring 4n for including circular metal material, card
Ring internal diameter and the flexible pipe blocked（2/5/6）External diameter adaptation, snap ring 4n circumferentially sets flexible clamp piece 4p（Metal fastener）, flexible pipe
（2/5/6）Lateral compression flexible clamp piece 4p when being inserted along the direction, and be embedded being jammed.That is flexible pipe（2/5/6）Inserting
It can be moved when entering in anticreep snap ring freely, being jammed when extracting anticreep snap ring can not be movable, so as to pass through the work(of anticreep snap ring
Spacing anti-drop function of the flexible pipe in joint can be realized.And return ring heads into the metal card of anticreep snap ring by the annulus of adaptation
Piece, and release flexible clamp piece 4p and effect is laterallyd secure to the first inner flexible tube, so as to release anticreep snap ring by return ring
Limit function realizes taking-up of the flexible pipe in joint.Described upper anticreep snap ring 4c, sidepiece anticreep snap ring 4h and lower anticreep snap ring
4j, and its corresponding sidepiece return ring 4g, lower return ring 4m features and function are same as above, and only size is variant.
The operation principle of anticreep snap ring and return ring is further illustrated as shown in Fig. 4-1 ~ 4-4, Fig. 4-1 is from the bottom to top
Top view, anticreep snap ring（4c/4h/4j）With return ring（4m/4g）For standard circular.Intercept longitudinal section details amplification such as Fig. 4-2
It is shown.Flexible pipe（5/6）Return ring is passed through along spacing direction（4m/4g）And insert extruding anticreep snap ring（4h/4j）, as Fig. 4-3 institute
Show, anticreep snap ring（4c/4h/4j）Uniform flexible clamp piece needs to recover deformation so as to have the snap-in force inwardly extruded, if soft
When pipe is extracted out, due to the effect of frictional force, flexible clamp piece can be driven to be extruded to center, cause frictional force to increase, it is soft so as to block
Pipe realizes spacing resistance to plucking function.As Suo Shi Fig. 4-4, it is necessary to when extracting flexible pipe, return ring（4m/4g）Up extrude and push up out anticreep
The flexible clamp piece and flexible pipe of snap ring（5/6）The contact of wall, releasing is spacing, and flexible pipe is smoothly downwardly drawn out.
The first thicker outer flexible tube 1 and the second outer flexible tube 6 are fixed by upper coupling 4a and lower coupling 4k respectively, upper outer
Joint 4a is screwed with the external screw thread 4d of connector 4 by clamp nut 3 and is matched the spacing anticreep for realizing flexible pipe, and is further improved
Sealing.Lower coupling 4k realizes the spacing anticreep of flexible pipe by lower anticreep snap ring 4j.
Fluid in first outer flexible tube 1 is freely migrated flowing in middle through hole 4i.The wherein fluid of outer flexible tube and inner flexible tube
Dust trajectory is independent of each other.Wherein middle through hole 4i position is in the external diameter of the first outer flexible tube 1 and the internal diameter of the first inner flexible tube 2 is distributed it
Between annulus on, uniform multilayer limber is used as the flow channel of outer flexible tube in the circle ring area.
The first thinner inner flexible tube 2 is nested in inside the second thicker outer flexible tube 1, i.e. the external diameter of the first inner flexible tube 2 is less than
The internal diameter of second outer flexible tube 1.And the second inner flexible tube 5 and the second outer flexible tube 6 are independently distributed.Wherein in the first inner flexible tube 2 and second
The model of flexible pipe 5 is consistent with diameter, and the first outer flexible tube 1 and the model of the second outer flexible tube 6 are consistent with diameter.The flexible pipe can be commercially
Buy, be nested type double two lead to connection mechanism be directly connected to object.
Its operation principle is：First inner flexible tube of upper nipple 4b connections 2 of four mouthfuls of distributing T-pipe body mechanisms of nested type, and lead to
It is spacing to cross anticreep snap ring 4c anticreeps；Secondly, the first outer flexible tube of upper coupling 4a connections 1, and flexible pipe is realized by clamp nut 3
Spacing anticreep.The second inner flexible tube of sidepiece nipple 4f connections 5, and it is spacing by sidepiece anticreep snap ring 4h anticreeps；Lower coupling
The second outer flexible tube of 4k connections 6, and it is spacing by lower anticreep snap ring 4j anticreeps.After four flexible pipe links, the first outer flexible tube
Fluid 1 flows in the middle through hole 4i of connector 4 by upper coupling 4a, the second outer flexible tube 6 is flow to from lower coupling 4k.The
The fluid of one inner flexible tube 2 is flowed in the inner via hole 4e of connector 4, flowed out to from sidepiece nipple 4f by upper nipple 4b
Second inner flexible tube 5.So as to realize the independent control to two circuits by the logical diversion mechanism of four mouthful two of the nested type, and by one
The tube-in-tube nesting type structure at end splits into the stand-alone configuration side by side of the other end.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
