Abstract
The utility model relates to the technical field of natural gas transportation, and discloses a special-shaped sleeve which comprises two opening ends, wherein the two opening ends are communicated, the communication position is a transition section, the outer diameters of the two opening ends are the same, the pore diameters of the two opening ends are different, and a filtering section is in stepped transition or arc transition. The pipe wall thickness of the special-shaped sleeve is 15mm to 30 mm. The length of the special-shaped sleeve is 300mm to 500 mm. The utility model meets the requirement of connecting the two ends of the pipeline with the same caliber and different outer diameters.
Description
Technical Field
The utility model relates to the technical field of natural gas transportation, in particular to a special-shaped sleeve.
Background
Most are cast iron material pipeline among the current underground piping, and this material pipeline has advantages such as easy operation, long service life, however, cast iron pipeline shortcoming is also comparatively obvious, has higher requirement promptly to the pipe base settlement, otherwise easily leads to pipeline fracture and kneck gas leakage and even produces the phenomenon that the interface drops, and this has great hidden danger to underground line safety in utilization. In the future, with the planning trend of the existing gas underground pipelines, cast iron pipes are gradually replaced by steel pipes and PE pipes to become main components of underground pipe networks, so that the condition that the original underground cast iron pipes are spliced with the steel pipes or the steel pipes are spliced with the PE pipes is bound to be generated in a large quantity, and the condition that the supply of the cast iron pipes is gradually reduced due to the shrinkage of the use amount of the existing cast iron pipes or even partial pipes are not produced any more. The situations result in that more steel replacement parts are needed in future construction, and in the future calandria construction and emergency repair work, more steel-cast connection, steel-plastic connection and cast connection situations are encountered.
When cast iron pipe and steel pipe are in splicing construction, because of the particularity of original material caliber, material, construction process limitation, corrosion resistance of the steel pipe and the like, the links of steel and cast two different material pipeline construction splicing are increased, wherein the main reason is that pipe fittings such as a sleeve, a flat bearing pipe (flat insertion pipe) and a steel flange plate are required to be connected in a conversion mode, because the number of parts required to be used is large, the number of connectors is large, the hidden danger risk in the future use process is increased, the excavated road surface is large, and the construction time is long.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems and provides a special-shaped sleeve which meets the requirement of connecting pipelines with the same opening diameter and different outer diameters at two ends.
The technical scheme adopted by the utility model is as follows:
the utility model provides a dysmorphism sleeve, characterized by includes two open ends, and two open ends intercommunication, the intercommunication position are the changeover portion, and the external diameter of two open ends is the same and the aperture is different, and the filter segment is ladder transition or pitch arc transition.
Further, the thickness of the pipe wall of the special-shaped sleeve is 15mm to 30 mm.
Further, the length of dysmorphism sleeve is 300mm to 500 mm.
The utility model has the beneficial effects that:
(1) the inner diameter sizes of bell mouths at two ends of the sleeve are respectively the size of a steel pipe with the same caliber and different outer diameters and the size of a cast iron pipe;
(2) the pipe fittings such as conversion pipe fittings, splicing interfaces, insertion pipes and the like required by the connection of pipelines made of different materials are reduced;
(3) the construction efficiency is accelerated, the potential safety hazard in use is reduced, and the excavation area is reduced.
Drawings
FIG. 1 is a schematic structural view of the present invention;
figure 2 is a schematic view of the installation of the present invention.
Detailed Description
The following describes in detail embodiments of the profile sleeve of the present invention with reference to the accompanying drawings.
Referring to the attached drawing 1, the special-shaped sleeve 1 comprises two opening ends 2, the two opening ends 2 are communicated, the communication position is a transition section 3, the outer diameters of the two opening ends 2 are the same, the pore diameters are different, and the filtering section 3 is in step transition or arc transition. The pipe wall thickness of the special-shaped sleeve 1 is 15mm to 30mm, and the length of the special-shaped sleeve 1 is 300mm to 500 mm.
Referring to fig. 2, during installation, the pipeline 4 made of different materials is only needed to be respectively matched with the two ends of the special-shaped sleeve 1, and the installation can be completed.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
