Abstract
The compensator of resistance to negative-pressure corrugated disclosed in the utility model, comprise ripple compensation pipe, the center section part tube wall of ripple compensation pipe is the tube wall of the continuous fluctuating that ridge and depressed part form, the two ends of described ripple compensation pipe are provided with adpting flange, the outer wall of described ripple compensation pipe is closely attached with rubber layer, the outer wall depression portion being positioned at described ripple compensation pipe is socketed with outer annular-stiffer, the inner wall depression place being positioned at described ripple compensation pipe is socketed with inside support ring, and the diameter of described inside support ring is greater than the diameter of outer annular-stiffer.The utility model adopts inside support ring and outer annular-stiffer to strengthen the anti-just or/and the ability of negative pressure of self, ensure the compensate function of bringing into normal play in pipe-line system, the material of each parts of the present utility model all has good wear resistance and corrosion resistance, can be used in more extensive and special pipe-line system.
Description
Technical field
The utility model relates to heating pipeline compensator technical field, is specifically related to a kind of compensator of resistance to negative-pressure corrugated.
Background technique
The compensator kind that pipeline junction under prior art adopts has the compensator of U-shaped curved formula, slip-type expansion joint, FlexbleJoint, wherein U-shaped curved formula compensator crushing is large, there is sealing problem in slip-type expansion joint, concrete easily occur running, emit, the problem such as leakage, in heat distribution pipeline, the gas, liquid, solid body of conveying has stronger corrosivity usually, gas, liquid, solid body can produce with its inwall when flowing through compensator and rub, and this will ask compensator except having good anti-corrosion capability also will have wear-resisting performance.Particularly, heat distribution pipeline by the impact of temperature, can expand with heat and contract with cold and pipeline can be made to produce malleation or/and negative pressure, and because the mechanism at compensator place is soft, the malleation produced in conveyance conduit or negative pressure can make compensator be out of shape and lose normal compensate function.
Summary of the invention
For the deficiencies in the prior art, this practicality provides a kind of ripple compensator of corrosion-resistant, wear-resistant, resistance to negative pressure.
To achieve these goals, the utility model solves the concrete technological scheme that its technical problem adopts: the compensator of resistance to negative-pressure corrugated, comprise ripple compensation pipe, the center section part tube wall of ripple compensation pipe is the tube wall of the continuous fluctuating that ridge and depressed part form, the two ends of described ripple compensation pipe are provided with adpting flange, the outer wall of described ripple compensation pipe is closely attached with rubber layer, the outer wall depression portion being positioned at described ripple compensation pipe is socketed with outer annular-stiffer, the inner wall depression place being positioned at described ripple compensation pipe is socketed with inside support ring, the diameter of described inside support ring is greater than the diameter of outer annular-stiffer.
The compensator of resistance to negative-pressure corrugated that the utility model provides further, the ring wall of its inside support ring is coated with corrosion resistant, wearing layer.
The compensator of resistance to negative-pressure corrugated that the utility model provides further, its corrosion resistant, wearing layer are fine and close polytetrafluorethylecoatings coatings.
The compensator of resistance to negative-pressure corrugated that the utility model provides further, its outer annular-stiffer is stainless steel.
The compensator of resistance to negative-pressure corrugated that the utility model provides further, the two ends oral area of its ripple compensation pipe is provided with flange, the fastening annular end face being attached at adpting flange of described flange.
The compensator of resistance to negative-pressure corrugated that the utility model provides further, its adpting flange is the stainless steel of metal.
The beneficial effects of the utility model: the utility model adopts inside support ring and outer annular-stiffer to strengthen the anti-just or/and the ability of negative pressure of self, ensure the compensate function of bringing into normal play in pipe-line system, the material of each parts of the present utility model all has good wear resistance and corrosion resistance, can be used in more extensive and special pipe-line system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place structure enlarged diagram of Fig. 1.
