Description
Technical Field
The utility model belongs to the technical field of tubular product, concretely relates to crossover sub is moulded with anti shearing force protecting pipe that subsides to gas pipeline steel.
Background
At gas pipeline construction field, change the junction in order to make steel to mould and can more firm connect, often adopt the retaining member to lock the processing to the junction, present processing mode generally with the plastic pipe capping to the steel pipe on, set up or do not set up the horse muzzle tooth on the position of cup jointing of steel pipe, then sheathe the retaining member in the position of cup jointing, the inside horse muzzle tooth that is provided with of retaining member to prevent the interface slippage. However, in the above arrangement, when the soil layer at the steel-plastic conversion interface of the pipeline is unevenly settled, especially when one side of the plastic pipe sinks violently, the plastic pipe at the port of the steel pipe becomes thinner due to the sleeving, so that the pipeline interface is easily misplaced and cracked to cause damage at the position, and in order to solve the problem, researchers adopt a mode of prolonging the length of the locking piece to prevent the pipeline interface from being damaged; however, the problem that a large gap is formed between a part of plastic pipe pipelines and the locking piece due to the change of the pipe diameter of the plastic pipe at the conversion joint cannot be solved well by simply prolonging the length of the locking piece, and the problem that the pipeline interface is damaged when the soil layer is unevenly settled cannot be solved; if the change of pipe diameter is considered, when the locking piece with the extension pipe diameter size difference is used for locking, because the pipe diameter is different, when the actual installation, the installation difficulty is increased, and the difficulty is brought to the site operation.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: the utility model provides a crossover sub is moulded with anti shearing force protecting pipe that subsides to gas pipeline steel, the torn defect at the pipeline kneck that has solved the pipeline that prior art exists because of the inhomogeneous settlement of soil causes, simple to operate, anti shear capacity is strong.
In order to solve the technical problem, the technical scheme of the utility model is that:
a settlement shearing force resistant protective sleeve for a gas pipeline steel-plastic adapter comprises a protective sleeve whole body, wherein the protective sleeve whole body is formed by connecting wide pipe sections and narrow pipe sections with different pipe diameters in an arc shape; the protective sleeve is integrally split into two equal semicircular pipes along the central line of the pipeline, a plurality of buckling devices are symmetrically arranged on the outer sides of the arc ends of the two semicircular pipes, each buckling device comprises a concave buckling seat and a convex buckling head, the outer sides of the two arc ends of one semicircular pipe are respectively provided with the concave buckling seats, and the outer sides of the two arc ends of the other semicircular pipe corresponding to the concave buckling seats are respectively provided with the convex buckling heads; the inner side of the arc-shaped end port provided with the concave buckle seat is provided with a convex head which protrudes outwards, and the inner side of the corresponding arc-shaped end provided with the convex buckle head is provided with a concave groove which protrudes inwards. The convex head and the concave groove can be correspondingly clamped.
Preferably, the port of the integral wide pipe section of the protective sleeve is bent inwards to form a folded port. The plastic pipe is protected. Like this, the locking piece at conversion kneck is just can be moulded to the parcel completely to wide pipeline section, and on the shearing force that produces when making subside conducted the locking piece, it met all right to have reduced conversion joint department atress to mould.
Furthermore, the length of the wide pipe section is matched with the length of the plastic pipe at the steel-plastic conversion interface (equal or the port of the wide pipe section is bent inwards to generate a folding opening to wrap the corresponding plastic pipe); the length of the narrow pipe section is 20-100 millimeters. The narrow pipe section can effectively protect a section of plastic pipe extending out from the steel-plastic conversion interface, and the compression of the shearing force generated by soil settlement on the plastic pipe at the steel-plastic conversion interface is reduced.
Preferably, 4 buckling devices are arranged and evenly arranged on the whole protective sleeve.
Preferably, the number of the buckling devices is 4, two of the buckling devices are respectively arranged at ports at two ends of the whole sheath pipe, and the other two buckling devices are arranged at two sides of the arc-shaped connection part of the wide pipe section and the narrow pipe section.
Preferably, the wall thickness of the whole protective sleeve is 3-8 mm.
Since the technical scheme is used, the beneficial effects of the utility model are that:
the utility model discloses a protective sleeve is whole except that through the locking piece of wide pipeline section parcel steel-plastic conversion kneck, still through the narrow pipeline section parcel one section plastic tubing outside being located steel-plastic conversion kneck, just so can effectually prevent because the shearing force that this plastic tubing near soil sinks and brings oppresses the plastic tubing, makes the plastic tubing sink, thereby makes steel-plastic conversion kneck produce to tear and lead to defects such as gas leakage; in addition, the whole protective sleeve is arranged into two semicircular pipes which are clamped together through the clamping device, so that the problem that the steel-plastic adapter is difficult to install due to different pipe diameters at the steel-plastic adapter during field installation is solved.
In a word, the utility model discloses simple to operate, anti-shear capacity is strong, can the tearing defect of pipeline kneck that causes because of the inhomogeneous settlement of soil that effectual solution prior art exists.
