Abstract
The utility model provides a novel sleeve compensator suitable for a high-temperature hot water pipeline comprising a composite structural core pipe (3) and a sealing element (2). An outer surface of the composite core pipe contacts closely with an inner surface of the sealing element, the composite core pipe moves a displacement along the axial direction respect to an outer shell (1). The sealing element is formed by sintering from the polytetrafluoroethylene filled with the molybdenum disulfide and the glass fiber; the sealing element is compressed tightly inside the outer shell, and is the self-lubricating composite structure. Not only the core pipe adopts the composite structure, but also the sealing material adopts the multiple material complex, which solves the disadvantages of the prior art. The utility model also has the advantages of the low coefficient of friction, the good sealing effect and the low price.
Description
Technical field:
The utility model relates to the device technique field of extraction duct displacement, especially a kind of novel sleeve expansion joint that is applicable to the high-temperature-hot-water pipeline.
Background technique:
At present, the multiple pattern of sleeve expansion joint can satisfy the application under most of conditions.Sleeve expansion joint is made up of parts such as shell, core pipe, sealing material, pressure rings, and the outer surface of compensator work city core pipe slidably reciprocates along axial direction with respect to sealing material, thereby realizes the purpose of compensation piping displacement.Because sleeve expansion joint is when work, its core tube outer surface part is that a part and medium contact in addition in the exposed environment externally, owing to be difficult for protection, be easy to generate corrosion, the frictional force when not only making compensator work increases, also make simultaneously sealing reliability reduce, cause leakage.。
Summary of the invention:
For solving the core pipe corrosion of sleeve expansion joint that prior art exists through being prone to after using, cause that frictional force increases, the deficiency of aspects such as sealing reliability reduction, the utility model provides a kind of novel sleeve expansion joint that is applicable to the high-temperature-hot-water pipeline, not only the core pipe has adopted composite structure, and sealing material also adopted the compound body of different materials, efficiently solves the defective of prior art.
For achieving the above object, the utility model adopts following technological scheme:
Described a kind of novel sleeve expansion joint that is applicable to the high-temperature-hot-water pipeline, it mainly is made up of the core pipe and the sealing component of composite structure, the outer surface of composite core pipe closely contacts with the internal surface of sealing component, and the composite core pipe has certain moving displacement with respect to frame along axial direction; Sealing component is filled molybdenum disulfide, glass fibre after sintering forms by teflon, and sealing component is pressed in the inside of frame, and is the composite structure of selflubricating.
Owing to adopted technique scheme, the utlity model has following superiority:
Described a kind of novel sleeve expansion joint that is applicable to the high-temperature-hot-water pipeline, the core pipe of its compensator adopts composite structure, can guarantee core pipe range phase non-corrosive, and the condition of necessity is provided for the sealing reliability of compensator; Its sealing component adopts teflon to fill molybdenum disulfide, glass fibre after sintering forms.Glass fibre can reinforced TFE intensity, molybdenum disulfide has good lubricity.Teflon is a kind of sealing material commonly used.Teflon is the copolymer of tetrafluoroethylene monomer, it has the chemical stability of height, good thermostability, good antifriction quality, excellent characteristics such as self lubricity can strengthen its mechanical strength, wear-resisting property, greasy property behind interpolation glass fibre, the molybdenum disulfide, are suitable for very much the sealing material as sleeve expansion joint, sealing component has adopted the good compound body of self-lubricating property, can guarantee the leak free operation that compensator is long-term.Advantage such as this compensator has that friction factor is low, good sealing effect, price are low.
Description of drawings:
Fig. 1 is this novel sleeve expansion joint structural representation;
Shown in Fig. 1: the 1-frame; The 2-sealing component; 3-composite core pipe.
Embodiment:
As shown in Figure 1, described a kind of novel sleeve expansion joint that is applicable to the high-temperature-hot-water pipeline, it mainly is made up of the core pipe and the sealing component of composite structure, the body portion of composite core pipe (3) is a carbon steel, with the contacted part of sealing material be stainless steel, the outer surface of composite core pipe (3) closely contacts with the internal surface of sealing component (2), realizes sealing, composite core pipe (2) can move along axial direction with respect to frame (1), the displacement of compensation pipeline; Sealing component (2) is filled molybdenum disulfide, glass fibre after sintering forms by teflon, sealing component (2) is pressed in the inside of frame, sealing component (2) has adopted the good compound body of self-lubricating property, the two combination can guarantee the leak free operation that compensator is long-term, but and is the composite structure of selflubricating.
Claims (1)
1, a kind of novel sleeve expansion joint that is applicable to the high-temperature-hot-water pipeline, it is characterized in that: it mainly is made up of the core pipe (3) and the sealing component (2) of composite structure, the outer surface of composite core pipe (3) closely contacts with the internal surface of sealing component (2), and composite core pipe (3) has certain moving displacement with respect to frame (1) along axial direction; Sealing component (2) is filled molybdenum disulfide, glass fibre after sintering forms by teflon, and sealing component (2) is pressed in the inside of frame (1), and is the composite structure of selflubricating.
