Especially on the industrial fabric dyeing machine of dyeing and finishing, what load in the primary tank is high temperature, high pressure and the dye liquor that contains the complicated chemical composition.In dyeing course, be an important ring for dye liquor heats and lowers the temperature, rely on external steam or cooling water to import in the interior pipeline of container, the temperature of utilizing the inside and outside temperature difference of pipeline to regulate dye liquor.And described pipeline also to need be the stainless steel manufacturing, and requirement can allow that this pipeline splits out from container, so that maintenance.Because high-temperature steam and cooling water all use same pipeline, the gap between pipeline and container can constantly be expanded and shrink because of the long-time and strong temperature difference, and both weld its weld seam and also are difficult to being involved for a long time, finally can crackle occur and lowers service life of a machine.
Summary of the invention
For solving all difficult problems that above-mentioned situation causes, the purpose of this utility model provides a kind of for dismounting, simultaneously also can bear the pipeline that the huge temperature difference and pressure have seal arrangement again, it is a kind of pipeline that can penetrate liquid-container, and leakage protection device is arranged, and can overcome because of the long-time and strong temperature difference and constantly expand and shrink the infringement of causing for pipeline and container wall intersection weld seam.
The scheme that the utility model technical solution problem adopts is, a kind of removable thermal sleeve is provided, be used for passing container shell, it comprises that pipeline (1), outer tube (2), cylinder (7) and extrusion (6) composition cylinder (7) are fixed on the container shell, extrusion (6) and leakproof material (3) place pipeline (1), between outer wall and cylinder (7) inwall, outer tube (2) is enclosed within outside the pipeline (1) and with pipeline (1) and is connected with one heart, between outer tube (2) and the pipeline (1) cavity (5) is arranged, pipeline passes container shell through the space in the cylinder.
A kind of removable thermal sleeve that the utility model provides, be provided with cushion rubber (4) between described extrusion (6) and the outer tube (2), at least one cushion rubber (4A) is positioned on the outer wall of extrusion (6), at least one cushion rubber (4B) is positioned on the inwall of extrusion, cushion rubber (4A) sealed cylindrical (7) inwall, cushion rubber (4B) sealed outer pipe (2) outer wall.
A kind of removable thermal sleeve that the utility model provides, described cavity (5) below is provided with air hole (13).
A kind of removable thermal sleeve that the utility model provides, pipeline (1) is positioned at the outer end of container shell and is provided with outward flange (8) and snap ring (10), snap ring (10) is installed on the groove of pipeline (1) outer wall, the external diameter of snap ring (10) is greater than the internal diameter of outward flange (8), and outward flange (8) relative duct size (1) can be rotated with one heart.
A kind of removable thermal sleeve that the utility model provides, described outward flange (8) is connected by screw (9) with lower flange (12), is separated with pad (11) between lower flange (12) and the pipeline (1).
When a detachable pipeline passes the perforation of shell of tank, can leave the convenient mounting or dismounting in gap between the two, yet liquid can be from clearance leakage.The encapsulating method that the utility model uses is realized with the form of extruding.The method of sealing is; the leakproof material of the flexible ring of a kind of tool is packed into space between pipeline and the perforation; in order to clog this space; after being fixed in belonging positions; put into the extrusion similar with leakproof material inside and outside footpath again; the extrusion inside and outside wall all has the silica gel sealing ring to contact outer tube outer wall and cylinder inner wall respectively, for the protection against leakage of many one decks is provided beyond the leakproof material.
Because pipeline is detachable, so extrusion and leakproof material also should be removed.After installing and removing repeatedly, its material should keep certain elasticity.When the leakproof material was extruded for a long time and does not remove, its spring-back force just can reduce.Even in case peripheral part gets loose, the surface weathers distortion, and the leakproof material can not in time be filled up the space of causing, the situation that just has leakage takes place.Especially in the design of heat exchanger, the steam that is used for heating and the cold water of cooling are shared same pipeline.Therefore the fluid temperature variations by pipeline can differ greatly, and it is inevasible that pipeline is out of shape because of temperature variation, so that caliber expanded the back and shrink because fluid temperature (F.T.) in the pipeline sharply descends, and causes the space.Even leakproof material elasticity is good, clogged the slight seepage of still having an opportunity before again in the space.
The utility model is for addressing this problem, and the scheme of employing is for overlapping the last layer outer tube again in described pipeline periphery, to replace the compressive plane of bigger tube wall as the leakproof material that stretch.Outer tube has only end to end and links to each other with one heart with pipeline, and both are separated by cavity.This cavity has air hole, can see through air hole when the interior air of cavity is expanded because pipeline is heated and discharge the pressure in the balance space.Because pipeline and outer tube do not have main surface of contact, heat energy is difficult to conduct on the outer tube from pipeline; And the air in the space also indirectly the heat energy that gives out of extraction duct drain, can conduct to the heat energy of outer tube thereby significantly reduce through material or air medium, make outer tube not yielding, to exempt leak of liquid.
Can plug into outer part easily for making pipeline be positioned at the outer end of container shell, the utility model uses a kind of flange Connecting format of non-angular restriction.Weld together between pipeline and the flange, and the other end pipeline of being plugged into also connects with the flange of same size.Under the situation that wherein an end pipeline need turn round, its angle just is subjected to the screw number restriction on the flange.Under design of the present utility model, wherein the flange of an end not and the trunnion welding, so the pipeline of opposite side can relatively rotate arbitrarily and not be subjected to the fixing restriction of flange.
