Abstract
The utility model relates to a ripple compensator internally lined with reinforced stiffness flow guiding casing, which is applicable to the two-way flow of media, the ripple compensator is obtained by adding a carbon steel pipe 2 in the stainless steel flow guiding casing 1 of the original ripple compensator, wherein one ends of the carbon steel pipe 2 and the stainless steel flow guiding casing 1 are fixed with a connecting short pipe 3 at the end by welding, the other end is joined with another connecting short pipe 3 in sliding way. By adding the carbon steel pipe 2, the characteristics of the stainless steel flow guiding casing 1 with low resistance to the flow and non-deposition of the feculency are reserved, the stiffness of the stainless steel flow guiding casing 1 is increased, the stainless steel flow guiding casing 1 is not easy to be curled up in the two way flow, thus overcoming the problems that the media is easy to be curled up in the two way flow due to the small stiffness of the flow guiding casing, thereby causing the compensator to be plugged and causing the problem that the media in the pipe can not normally flow; and so the ripple compensator has a wider scope of application.
Description
One, technical field
The utility model relates to the FlexbleJoint that a kind of city heat supply pipeline is used, and is the FlexbleJoint that a kind of liner that adapts to the medium two-way flow strengthens rigidity water conservancy diversion sleeve pipe.
Two, background technique
FlexbleJoint mainly is to be used for absorbing the piping attachment that heat supply pipeline expands with heat and contract with cold, owing to be wave structure, when making media flow local resistance bigger, and the easy deposit dirt in ripple place, so liner water conservancy diversion sleeve pipe is set, in FlexbleJoint to reduce resistance and dirt deposition.But the water conservancy diversion sleeve structure of FlexbleJoint liner only allows medium to press definite direction one-way flow at present, if adopt two-way flow, very easily causes liner water conservancy diversion sleeve pipe to be rolled, and causes compensator to stop up, and makes that medium can not proper flow.And the thickness of increase water conservancy diversion sleeve pipe can cause the increase of stainless steel material use amount again, is unfavorable for saving cost.Under this background, the utility model provides a kind of novel liner to strengthen the FlexbleJoint of rigidity water conservancy diversion sleeve pipe, by in the stainless steel diversion sleeve pipe of former FlexbleJoint liner, adding carbon steel tubing, form the double-deck water conservancy diversion sleeve structure of " pipe-in-pipe ", both saved cost, can increase the rigidity of water conservancy diversion sleeve pipe again, make it can not only reduce fluid resistance and dirt deposition, and can adapt to the two-way flow of flowing medium, prevent that liner water conservancy diversion sleeve pipe from rolling, make the Applicable scope of FlexbleJoint of the present invention more extensive.
Three, summary of the invention
The FlexbleJoint that liner of the present invention strengthens rigidity water conservancy diversion sleeve pipe is to add carbon steel tubing 2 to obtain in the stainless steel diversion sleeve pipe 1 of FlexbleJoint liner, one end of carbon steel tubing 2 and stainless steel diversion sleeve pipe 1 is fixed by welding with the short tube 3 that is connected of this end, and the other end is connected short tube 3 slips and is connected with another.By adding carbon steel tubing 2, the characteristics that stainless steel diversion sleeve pipe 1 convection cell resistance is little and dirt does not deposit have not only been kept, also increased the rigidity of stainless steel diversion sleeve pipe 1, make when the medium two-way flow, stainless steel diversion sleeve pipe 1 can not form irregular folding (nest becomes the spitball shape) because of the reverse flow of water, be jammed in the compensator, thus shadow the proper flow of Xiangshui County.Solve stainless steel diversion sleeve pipe 1 and easily be folded because of rigidity is little and roll, stopped up the problem of current.
Four, description of drawings
Accompanying drawing 1 is that liner strengthens the sectional structure chart of the FlexbleJoint of rigidity water conservancy diversion sleeve pipe, and wherein 1 be the stainless steel diversion sleeve pipe, and 2 is the carbon steel tubing that increases newly, and 3 is FlexbleJoint and the short tube that is connected of heat supply pipeline, and 4 is the FlexbleJoint bellows.
Five, embodiment
The invention provides the FlexbleJoint that a kind of liner strengthens rigidity water conservancy diversion sleeve pipe, it is to add carbon steel tubing 2 to obtain in the stainless steel diversion sleeve pipe 1 of FlexbleJoint liner, one end of carbon steel tubing 2 and stainless steel diversion sleeve pipe 1 is fixed by welding with the short tube 3 that is connected of this end, the other end is connected short tube 3 slips and is connected with another, wherein the outer wall of carbon steel tubing 2 closely contacts with the inwall of stainless steel diversion sleeve pipe 1, perhaps there is the space that is not more than 0.3mm between the two, the material of stainless steel diversion sleeve pipe 1 is preferably stainless steel SUS316 or 316L, pipe thickness is preferably 2mm, the material of carbon steel tubing 2 is preferably the Q235B carbon steel, pipe thickness is preferably 6mm, the diameter that is connected short tube 3 and the heat supply pipeline equal diameters of FlexbleJoint and heat supply pipeline, be preferably 100mm-1200mm, the material of FlexbleJoint bellows 4 is preferably stainless steel SUS316 or SUS316L.Fixing by end welding, the other end is connected the Placement of sliding, can guarantee expanding with heat and contract with cold of compensator extraction duct, reduce fluid resistance and dirt deposition, rigidity is big by adding simultaneously, be difficult for rolled-up carbon steel tubing 2 during reverse fluid flow, can make its outside Stainless Steel Tube water conservancy diversion sleeve pipe 1 can not be rolled-up, adapts to two-way the flowing of medium, make that when the ripple free state being connected length deducts ripple pre-stretching length 〉=15mm, can prevent that dirt from entering in the ripple.
