Description

The flexible connecting device of socket joint pipe

Technical field

The utility model relates to pipeline and connects, and is a kind of flexible connecting device of socket joint pipe.

Background technique

Pipeline transport be with pipeline as the means of transportation of a kind of long distance delivery liquids and gases goods and materials of means of transportation, have freight volume large, take up an area less, the pipeline transport construction period is short, expense is low, pipeline transport is safe and reliable, continuity is strong, pipeline transport consumes energy less, cost is low, profitable advantage.Pipe is the main member forming pipeline, pipe has steel pipe, cast iron tube, concrete reinforced pipe, nonmetallic pipe several by material, Placement has socket joint connection, Flange joint, welding, bonding several, socket joint to connect to be convenient and swift during pipe connects, Placement safely and efficiently, and Problems existing is: during installation, because caliber is large, size is long, and sealing intensity is large, so power required when installing is larger, the gap between bellmouth and socket can not be grasped, often easy dieback.Time to temperature height, expand with heat and contract with cold because material can produce, the steel pipe after dieback can produce to be heaved, and there is potential safety hazard.

Model utility content

Technical problem to be solved in the utility model is: the shortcoming overcoming prior art, there is provided a kind of structure simple, easy for installation, sealing intensity be good, be connected firmly, convenient disassembly, the flexible connecting device of the socket joint pipe in required gap when socket joint pipe is installed can be controlled

The scheme of the utility model technical solution problem is: a kind of flexible connecting device of socket joint pipe, it comprises pipe, first flange, second flange and bolt, one end of described pipe is provided with bellmouth, the other end is provided with socket, be socketed the first flange after the bellmouth of pipe and be connected, be socketed the second flange after the socket of pipe and be connected, first flange and the second flange arrange some through holes and mutual correspondence respectively, it is characterized in that: also comprise locking nut, anti-return nut and stop nut, described two tubes is placed in the bellmouth position relative with socket, the socket that the bellmouth of pipe is socketed in another root pipe is connected, one end of bolt is installed in the first flange through hole of bell of pipe place socket, bolt is connected by two locking nuts and the first flange being placed in the first flange both sides respectively, the other end of bolt is installed in the second flange through hole of another root tube socket place socket, bolt is by being placed in anti-return nut outside the second flange and the second flange is connected, bolt between the second flange and anti-return nut is socketed stop nut.

Described tube socket outer surface socket seal ring also sealing is connected.

The using method of the flexible connecting device of the utility model socket joint pipe is: calculate the size that socket enters bellmouth, first bolt is connected by two locking nuts and the first flange, when bellmouth, socket grafting, take bolt as guiding, insert in through hole corresponding to the second flange by bolt, bellmouth part is brought into cover and receive in socket and go, after the size that the size conforms entering bellmouth to socket calculates, stop grafting, first screw in stop nut, then screw in anti-return nut.

The beneficial effect of the flexible connecting device of the utility model socket joint pipe is: the flexible structure of its flange and stop nut can either control axial clearance when mounted, can ensure that again pipeline carries out axial displacement and do not produce leakage in certain scope, can also prevent from producing radial displacement between bellmouth and socket, when ambient temperature rising pipe heat rises, prevent from pipe dieback from producing to heave, again can when ambient temperature reduces pipe shrinkage, prevent pipe shrinkage from producing gap and leaking, there is structure simple, practical and convenient, with low cost, the advantage of Be very effective.

Accompanying drawing explanation

Fig. 1 is the structural representation of the flexible connecting device of the utility model socket joint pipe.

In figure: 1 first flange, 2 locking nuts, 3 bellmouths, 4 seal rings, 5 bolts, 6 insert, 7 second flanges.8 stop nuts, 9 anti-return nuts.

Embodiment
