Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the specific embodiment of the present invention.
A kind of nesting type provided by the invention four mouthfuls of distributing T-pipe mechanisms, as shown in Figure 1, this mechanism comprises gland nut 3 and connecting body 4 to entirety.Upper spigot 4b wherein in connecting body 4 and sidepiece spigot 4f are connected the first inner flexible tube 2 and the second inner flexible tube 5 respectively, and the upper socket 4a in connecting body 4 and lower socket 4k are connected the first outer flexible tube 1 and the second outer flexible tube 6 respectively.
Described gland nut, it is characterized in that annulus hollow allows the first outer flexible tube 1 to pass, its lower end jointing arranges conical internal thread and mates with the outside thread 4d of connecting body 4.
As a kind of preferred version, connecting body 4, upper socket 4a, upper spigot 4b, outside thread 4d, sidepiece spigot 4f, sidepiece return ring 4g, middle through hole 4i, lower socket 4k process casting by whole block material, then at upper spigot 4b, sidepiece spigot 4f with anticreep snap ring assembles respectively in lower socket 4k place and return ring forms.
The first thinner inner flexible tube 2 is fixed respectively by upper spigot 4b and sidepiece spigot 4f, by upper anticreep snap ring 4c and the spacing anticreep of sidepiece anticreep snap ring 4h, and improves sealing further.Fluid in first inner flexible tube 2 is migrated flowing in inner via hole 4e.Wherein, the position of inner via hole 4e is in the centre of spigot 4b cylinder, is an aperture run through, as the flow channel of inner flexible tube.
The snap ring 4n comprising circular metal material of upper anticreep snap ring 4c, sidepiece anticreep snap ring 4h and lower return ring, snap ring internal diameter is adaptive with the external diameter of the flexible pipe (2/5/6) blocked, snap ring 4n circumferentially arranges flexible clamp piece 4p(metal fastener), lateral compression flexible clamp piece 4p when flexible pipe (2/5/6) inserts along this direction, and embedding is wherein jammed.Namely flexible pipe (2/5/6) can move freely when inserting in anticreep snap ring, and being jammed when extracting anticreep snap ring cannot be movable, thus passes through the spacing anti-drop function of functional realiey flexible pipe in joint of anticreep snap ring.And return ring heads into the Metallic card of anticreep snap ring by adaptive annulus, and remove the side direction fixation of this flexible clamp piece 4p to the first inner flexible tube, thus realize the taking-up of flexible pipe in joint by the limit function of return ring releasing anticreep snap ring.Described upper anticreep snap ring 4c, sidepiece anticreep snap ring 4h and lower anticreep snap ring 4j, and the sidepiece return ring 4g of correspondence, lower return ring 4m Characteristic and function are the same, only size is variant.
As shown in Fig. 4-1 ~ 4-4, further illustrate the working principle of anticreep snap ring and return ring, Fig. 4-1 is plan view from the bottom to top, and anticreep snap ring (4c/4h/4j) and return ring (4m/4g) are standard circular.Intercept longitudinal section details to amplify as shown in the Fig. 4-2.Flexible pipe (5/6) passes return ring (4m/4g) along spacing direction and inserts extruding anticreep snap ring (4h/4j), as shown in Fig. 4-3, the uniform flexible clamp piece of anticreep snap ring (4c/4h/4j) needs to recover distortion thus the snap-in force with inwardly extruding, if when flexible pipe is extracted out, due to the effect of frictional force, flexible clamp piece can be driven to extrude to center, cause frictional force to increase, thus block flexible pipe and realize spacing resistance to plucking function.As shown in Fig. 4-4, when needing to extract flexible pipe, return ring (4m/4g) up extrudes and backs down the flexible clamp piece of anticreep snap ring and the contact of flexible pipe (5/6) wall, and remove spacing, flexible pipe is extracted downwards smoothly.
The first thicker outer flexible tube 1 and the second outer flexible tube 6 are fixed respectively by upper socket 4a and lower socket 4k, and upper socket 4a screws with the outside thread 4d of connecting body 4 the spacing anticreep mating and realize flexible pipe by gland nut 3, and improves sealing further.Lower socket 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.Wherein the fluid migration path of outer flexible tube and inner flexible tube is independent of each other.Wherein the position of middle through hole 4i is on the annulus between the first outer flexible tube 1 external diameter and the distribution of the first inner flexible tube 2 internal diameter, and in this circle ring area, uniform multilayer limber is used as the flow channel of outer flexible tube.
It is inner that the first thinner inner flexible tube 2 is nested in the second thicker outer flexible tube 1, and namely the external diameter of the first inner flexible tube 2 is less than the internal diameter of the second outer flexible tube 1.And the second inner flexible tube 5 and the independent distribution of the second outer flexible tube 6.Wherein the first inner flexible tube 2 is consistent with diameter with the second inner flexible tube 5 model, and the first outer flexible tube 1 is consistent with diameter with the second outer flexible tube 6 model.This flexible pipe can commercially have been bought, and is the direct connecting object that nesting type two two leads to connection mechanism.
Its working principle is: the upper spigot 4b of nesting type four mouthfuls of distributing T-pipe body mechanisms connects the first inner flexible tube 2, and spacing by upper anticreep snap ring 4c anticreep; Secondly, upper socket 4a connects the first outer flexible tube 1, and realizes the spacing anticreep of flexible pipe by gland nut 3.Sidepiece spigot 4f connects the second inner flexible tube 5, and spacing by sidepiece anticreep snap ring 4h anticreep; Lower socket 4k connects the second outer flexible tube 6, and spacing by lower anticreep snap ring 4j anticreep.After four flexible pipe links, the fluid 1 of the first outer flexible tube is by upper socket 4a, and in connecting body 4, through hole 4i flows, and flow to the second outer flexible tube 6 from lower socket 4k place.The fluid of the first inner flexible tube 2, by upper spigot 4b, flows at the inner via hole 4e of connecting body 4, flows out to the second inner flexible tube 5 from sidepiece spigot 4f place.Thus achieved by the logical distributary mechanism of this nesting type four mouthful two independence of two circuits is controlled, and the pipe-in-pipe nesting type structure of one end is split into the stand-alone configuration side by side of the other end.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
