Abstract
The utility model relates to a flexible connector for a metal pipeline, comprising ordinary locking nuts and a pipe body two parts, wherein, the skin layer of the pipe body is provided with interphase annular concave ditches and annular convex sections, the skin layer of the whole pipe body is integration, the nuts are sheathed on the pipe body, and the pipe body is made of stainless steel material or carbon steel material. Because the connector is a flexible pipe body, the connector can be conveniently processed into the connector with desired curvature radius, and the bore diameter of the connector can not be altered. When the pipeline is connected, the nuts of the connector are just screwed on the screw thread of the pipeline to lock tightly, and the operation is simple. The expansion displacement caused by temperature difference can be compensated, the service life of the pipeline can be extended, and the noise when fluid medium operates in the pipeline can be eliminated.
Description
The utility model relates to a kind of link that is used for flowing medium piping erection.
At present, more the corner of metallic conduit is adopted the right angle to turn the connection of reduction of fractions to a common denominator section or is adopted bend pipe to connect, and pipeline and link are all wanted mantle fiber or needed welded joint, operate numerous rope; Bend pipe must be made with special device, otherwise pipeline drift diameter will change promptly usually said " flat curved "; Pipeline after the connection is rigid state, medium by the time because temperature difference influence produces noise, damage pipeline sometimes and cause leakage.
The purpose of this utility model is to provide a kind of and is processed into required form easily, and easy to operate metallic conduit flexible connector during connecting tube.
Technical solution of the present utility model is: the metallic conduit flexible connector comprises nut 1 body 4.The top layer of body 4 is alternate annular concave ditch 5 and convex annular joint 6, and the whole top layer of body 4 is an one; Nut 1 is enclosed within on the body 4, and the end of body 4 is the boss 3 that is higher than convex annular joint 6, and packing ring 2 is nut 1 in and the boss 3 that reclines, and body 4 employing stainless steels or charcoal steel are made material.
According to technique scheme, because of link is annular ring shape flexible pipe body, can select the body of different length during installation for use, by hand or by simple tools, be processed into required radius of curvature, its latus rectum can not change.Then nut is screwed on the threaded pipeline and gets final product.Easy and simple to handle.This link can compensate the breathing displacement that the temperature difference causes, has prolonged pipeline working life, has eliminated the noise when flowing medium moves in pipeline.
Accompanying drawing 1 is a partial sectional view of the present utility model.
Accompanying drawing 2 is a quarter bend shape schematic representation of the present utility model.
Accompanying drawing 3 is a S bending shape schematic representation of the present utility model.
Accompanying drawing 4 is a U-shaped bending shape schematic representation of the present utility model.
In conjunction with the accompanying drawings, a kind of embodiment of the present utility model is described.The metallic conduit flexible connector comprises common nut 1, is the body 4 of material with the charcoal steel.The top layer of body 4 is alternate annular concave ditch 5 and convex annular joint 6, and the whole top layer of body 4 is an one; Earlier nut 1 is enclosed within on the body 4, the end points with body 4 is squeezed into boss 3 then, and boss 3 is higher than convex annular joint 6, and rubber washer 2 is in nut 1 and the boss 3 that reclines.Body 4 can be processed into different shapes such as quarter bend, S shape are curved, U-shaped is curved as required, during installation nut 1 is screwed in to lock on the screw thread of pipeline to get final product.
Claims (2)
