Fig. 1 is the overall structure schematic diagram of a kind of pipeline multichannel of the present invention elasticity crossing cabin part.
Fig. 2 is the plan view of Fig. 1.
In figure: the little path tube of 1-, 2-inner tube, the spacing platen of 3-, 4-socket head screw, 5-sleeve pipe, 6-elastomer, 7-weld seam, 8-welding seat, 9-bulkhead, 10-gasket seal, 11-inner tube limited ring.
Embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.
As shown in attached Fig. 1 and 2, comprise little path tube 1, inner tube 2, spacing platen 3, socket head screw 4, sleeve pipe 5, elastomer 6, welding seat 8, gasket seal 10 and inner tube limited ring 11;
The number of described little path tube 1 is four, and two ends are with threaded joint;
The cylindrical cavity structure that described inner tube 2 is sealing;
The inner chamber of described sleeve pipe 5 is toroidal cavity, and the aperture at sleeve pipe 5 two ends is greater than the external diameter of inner tube 2, and sleeve pipe radially extends annular protrusion structure on 5 inner peripheral surface, can further strengthen the sulfurating strength of elastomer 6 and inner tube 2;
The internal diameter of described spacing platen 3 is greater than the external diameter of inner tube 2 but is less than the aperture at sleeve pipe 5 two ends;
Described elastomer 6 is epoxide resin material;
On one side surface of described welding seat 8, be processed with protruding structure;
Its integrated connection closes: the two ends of little path tube 1 are radially passed respectively the both ends of the surface up and down of inner tube 2 and welded together with it, inner tube 2 is positioned on the circumferential surface of sleeve pipe 5 inside and is fixedly connected with vertically inner tube limited ring 11, inner tube 2, inner tube limited ring 11 and sleeve pipe 5 coaxially sulfide by elastomer 6, and spacing platen 3 is fixedly connected with two end faces of sleeve pipe 5 by socket head screw 4; Welding seat 8 is welded on the outer peripheral surface of sleeve pipe 5, and there has been the weld seam 7 of connection function welding part; Inipple connected system pipeline, the protruding structure of welding seat 8 is connected with after the groove fit on bulkhead 9, between protruding structure and groove, by gasket seal 10, is sealed.
Further, together with the spacing platen 4 at inner tube 2, inner tube limited ring 11 and sleeve pipe 5 two ends, form the limit function of crossing cabin part, radially spacingly by inner tube limited ring 11 and spacing platen 4, realized, axial limiting is realized by spacing platen 4 and inner tube 2; The vibration isolation ability of crossing cabin part is realized by elastomer 6, and inner tube limited ring 11 is also conducive to improve the sulfurating strength of elastomer 6 and inner and outer pipes simultaneously, improves sealability.Because the internal diameter of sleeve pipe 5 and spacing platen 3 is greater than the external diameter of inner tube 2, inner tube 2 is arranged on sleeve pipe 5 inside as floated, so crossing cabin part possesses displacement compensation capability.
During the work of crossing cabin part, the pressure that acts on whole crossing cabin part has flowing pressure and separation pressure in pipe, and in pipe, flowing pressure is born by little path tube 1, and little path tube 1 adopts inipple to be connected with system piping; Separation pressure is mainly born by elastomer 6 and the sulfurating strength of inner tube 2 and sleeve pipe, sleeve pipe 5 is connected by welding seat 8 with bulkhead 9, with gasket seal 10, seal, under the effect of the spacing power of separation pressure and crossing cabin part inner and outer pipes, elastomer 6 deformed dilation that is squeezed, selfsealings intensity further improves.
