Metal compensator

Technical Field

The utility model relates to the technical field of compensators, in particular to a metal compensator.

Background

The compensator is also called as an expansion joint and an expansion joint, and consists of accessories such as a corrugated pipe, a support, a conduit and the like, and the metal compensator is used for compensating axial displacement and also can compensate transverse displacement or the combined displacement of the axial displacement and the transverse displacement, has the capacity of compensating angular displacement, and generally has the capacity of expansion and expansion. Due to thermal elongation or temperature stress causing deformation or failure of the pipe, it is necessary to provide a compensator on the pipe to compensate for the thermal elongation of the pipe and thereby reduce the stress on the pipe wall and the forces acting on the valve member or the support structure.

Now, the metal compensator that usually adopts sealing connection, for example, chinese utility model patent with publication number CN206817029U discloses "a turn-ups formula sealing connection metal compensator", it adopts double-deck turn-ups form and flange lug connection through the bellows to in the compensator, the welding bead between takeover and carbon steel and the stainless steel in the middle of having saved, improve the life of compensator, reduce the emergence of compensator leakage accident, there is the defect in this kind of mode through double-deck turn-ups form and flange lug connection, because in long-term use, the turn-ups rubs with the device that meets, lead to the turn-ups to take place to damage, easily take place the compensator effect and become invalid, thereby lead to pipeline deformation or destruction.

SUMMERY OF THE UTILITY MODEL

The utility model provides a metal compensator which can effectively protect a pipeline, prevent the pipeline from deforming or damaging in work and prolong the service life of the pipeline, in order to overcome the problems that the flange is directly connected with a flange in a double-layer flange mode, and the flange is damaged due to friction between the flange and a connected device in the long-term use process, so that the pipeline is deformed or damaged due to the failure of the compensator.

The utility model adopts the following technical scheme for solving the technical problems: the utility model provides a metal compensator, includes bellows and honeycomb duct, the honeycomb duct outside is equipped with the bellows, the outside of bellows is equipped with the lag, the both sides of honeycomb duct are equipped with the flange, the outside of flange is equipped with the otic placode, the flange of honeycomb duct both sides passes through the screw rod and connects.

Further, the lag cup joints the outside at the honeycomb duct.

Further, the screw rod is fixed at the lug plate through a bolt.

Furthermore, the two ends of the protecting sleeve are connected with the flow guide pipe in a sliding mode.

Furthermore, the two sides of the flow guide pipe are provided with external threads, and the flow guide pipe is connected with the flange through threads.

Furthermore, a plurality of threaded holes are formed in the flange, and the other end of the flange is connected with the connecting pipe through the threaded holes.

Furthermore, the flow guide pipe and the corrugated pipe are made of metal materials.

Furthermore, the inner surface and the outer surface of the flow guide pipe are coated with anti-corrosion substances.

Compared with the prior art, the metal compensator has the advantages that the guide pipe, the flange, the corrugated pipe, the protecting sleeve, the ear plate and the screw are arranged to be matched with each other, so that the purpose of protecting a guide pipeline is achieved, the corrugated pipe has the capability of expanding and contracting, the guide pipe is prevented from deforming or damaging in work, and the service life of the pipeline is prolonged; the protective sleeve is arranged on the outer side of the corrugated pipe, so that the corrugated pipe is protected from being influenced by the external environment, and the corrugated pipe is prevented from being damaged.
