Description
Technical field
The utility model relates to a kind of pipe network device, especially for the hermetically sealed sleeve expansion joint of the self-closing of directly buried installation pipe network, belongs to the pipe fitting technical field.
Background technique
Fast development along with urban construction, the city confined space is restricted day by day, directly buried installation pipe network mode has become the development trend that urban pipe network lays, and the directly buried installation pipe network more and more embodies its advantage, but the pipe network heat compensating unit is also had higher requirement thereupon.Traditional corrugated expansion joint is because its intrinsic structure and processing technology, the stress corrosion of being left over, intergranular corrosion, welding stress, shapes residual stress, displacement stress, thermal stress and Cl
-Problems such as corrosion can not satisfy the requirement of modern construction comprehensively.At present, the directly buried installation pipe network of city heat supply is for solving and adapting to the requirement that heating network has compensation directly buried installation technology, and sleeve expansion joint commonly used is as the pipe network compensating device.The Sealing of ordinary cartridge compensator adopts the graphite packing, the problem that this Sealing exists is: in the bigger heating network of temperature variation, the graphite packing produces sealability decline because of aging hardening easily, therefore needs periodic replacement, and its life time is one to two year usually.Change Sealing labor intensive material resources, bring bigger trouble for the maintenance use of pipe network.
The model utility content
Technical problem to be solved in the utility model is: a kind of hermetically sealed sleeve expansion joint of self-closing that the various forms pipe network lays requirement, maintenance-free that satisfies is provided.
The alleged problem of the utility model is solved by following technological scheme:
The hermetically sealed sleeve expansion joint of a kind of self-closing, it comprises compensation core body and symmetrically arranged end cap, seal ring, guiding core body, position, described compensation core body endoporus both sides respectively with a side cylindrical Spielpassung of left and right guiding core body, end cap is fixed on compensation core body end, its specialization is: be respectively equipped with the annular groove in L shaped cross section between described compensation core body and two end cap, described seal ring is a V-shaped seal ring, and its profile and annular groove are adaptive, seal ring is arranged in annular groove, and the seal ring lip inwardly is provided with.
The hermetically sealed sleeve expansion joint of above-mentioned self-closing, described each annular groove bottom uniform 2-4 pod apertures, pod apertures communicates with the matching gap of compensation core body, guiding core body.
The hermetically sealed sleeve expansion joint of above-mentioned self-closing, described seal ring thickness B is the 30-40 millimeter, pod apertures diameter 2-3 millimeter.
The hermetically sealed sleeve expansion joint of above-mentioned self-closing, described compensator also is provided with uniform guide blot and clamping bolt, described guiding core body is provided with positioning disk, and it is fastening with it that described clamping bolt passes the both sides end cap, and described guide blot passes positioning disk and is slidingly matched with positioning disk.
The utility model improves at the problem that directly buried installation pipe network ordinary cartridge compensator commonly used needs periodic maintenance to change Sealing.The used seal ring of this compensator adopts ethylene propylene diene rubber to make, and is to have the V-shaped seal ring of widening sealing strip, is provided with pod apertures for improving sealing effect at the lip place of seal ring.Above-mentioned improvement can make seal ring produce good self-closing seal action, and the pipe internal pressure is big more, and self-closing sealing effect is good more.Design of the present utility model can guarantee that sealing gasket is not overflowed when the motion of guiding core body, even after using rubber that to a certain degree aging taken place for a long time, the V-seal pad produces self-closing seal action makes it still can be close to the guiding core surface, guarantees excellent sealing performance.The utility model is suitable for the suitable urban heating network of straight-run, have good as Security, the life-span is long, easy for installation, can direct-burried, the characteristics of maintenance-free after the installation and operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is Figure 1A portion partial enlarged view.
Label is expressed as follows in the accompanying drawing: 1. core body leads; 2. positioning disk; 3. end cap; 4. clamping bolt; 5. compensation core body; 6. pod apertures; 7. seal ring; 8. annular groove; 9. guide blot.
Embodiment
Referring to Fig. 1, the utility model formation comprises compensation core body and symmetrically arranged end cap 3, seal ring 7, core body 1 leads.One side cylindrical of each core body that leads lays respectively at the endoporus both sides of compensation core body 5, compensation core body endoporus and guiding core body cylindrical Spielpassung.For the hermetically sealed sleeve expansion joint of the self-closing of different size, the axial displacement X between the two guiding core bodys is the 60-420 millimeter.Two end cap 3 symmetries are fixed on compensation core body end.Compensating the annular groove 8 that core body 5 and 3 of two end cap are respectively equipped with L shaped cross section, described seal ring 7 is a V-shaped seal ring, and its profile and annular groove are adaptive, and seal ring is arranged in annular groove, and the seal ring lip inwardly is provided with.Described compensator also is provided with uniform guide blot 9 and clamping bolt 4, and guide blot and clamping bolt arranged spaced in the illustrated embodiment, have adopted root guide blot, three clamping bolts.Described guiding core body is provided with positioning disk 2.It is fastening with it that described clamping bolt passes the both sides end cap, and guide blot passes positioning disk and is slidingly matched with positioning disk.The guiding core body can be realized compensator straight-line displacement and axial limiting under the effect of guide blot.
Referring to Fig. 1, Fig. 2, described each annular groove bottom uniform 2-4 pod apertures 6, pod apertures communicates with the matching gap of compensation core body, guiding core body, and the pressurized gas in the compensator can affact the lip place of seal ring 7 by pod apertures.Described seal ring thickness B is the 30-40 millimeter, pod apertures diameter 2-3 millimeter.
Seal ring of the present utility model is a critical component of realizing the hermetically sealed compensator of self-closing, also is technological core of the present utility model.The sealing circle selects for use ethylene propylene diene rubber as sealing material, has anti-weather, ozone resistance and the heat-resistant aging of excellent chemical stability, brilliance, also has good low-temperature resistance, electric edge etc.Seal ring is selected V-structure for use, and its lip limit inwardly is provided with, and under the manifold pressure effect, the lip limit is opened and played good self-closing seal action.Seal ring is installed in the annular groove in L shaped cross section, because the glade plane space of guiding core body cylindrical and compensator core body endoporus is minimum, can guarantee that sealing gasket is not overflowed.Even seal ring has to a certain degree aging after using the more than ten years, but in a complete seal space, under the manifold pressure effect, it still is close to the guiding core surface, realizes the hermetically sealed compensation of self-closing.In addition, the pod apertures of the utility model design can guarantee that the pressure in the pipeline is delivered to the seal ring place effectively.
