Abstract
The utility model provides an expansion joint of a pipeline. The expansion joint of the pipeline comprises a right flange, a sleeve pipe, an expansion pipe, a check ring, a stuffing box, a compression ring, a stud, a left flange, a compression ring flange, a nut and an expansion pipe flange, wherein the check ring is welded on the inner wall of the left end of the sleeve pipe, the expansion pipe is in clearance fit with the check ring and stretches into the sleeve pipe for 150-200 mm, the stuffing box is arranged on the left side of the check ring, the compression ring is arranged between the sleeve pipe and the expansion pipe in a movable fit mode and is located on the left side of the stuffing box, the left end face and the right end face of the sleeve pipe are respectively fixedly connected with the left flange and the right flange, the left end face of the expansion pipe is fixedly connected with the expansion pipe flange, the left end face of the compression ring is fixedly connected with the compression ring flange, the nut is arranged at the left end of the stud, and the right end of the stud penetrates through a bolt hole in the compression ring flange to be connected with a threaded hole in the left flange in a threaded mode. The expansion joint of the pipeline has the advantages of being tight in connection, not prone to leakage, and large in expansion degree.
Description
Technical field
The utility model relates to a kind of telescope jiont for pipe, refers more particularly to a kind of large-scale pipeline expansion joint, the metal conduit field of engineering technology.
Background technique
Due to the reason of expanding with heat and contract with cold, all to use flexible pipe joint in pipelayer's journey, present flexible pipe joint all is comprised of the structure that ring in rubber is stuck on the steel outer shroud, and this flexible pipe joint dilatability is little, is not suitable for using in the large large-scale field pipeline construction work of the temperature difference.
Summary of the invention
The purpose of this utility model is to provide a kind of telescope jiont for pipe, is used for addressing the above problem.
the technical solution of the utility model is: a kind of telescope jiont for pipe, comprise right flange, sleeve pipe, telescopic pipe, back-up ring, stuffing box, pressure ring, stud bolt, left flange, the pressure ring flange, nut and telescopic pipe flange, with welding manner, back-up ring is set on sleeve pipe left end inwall, telescopic pipe and back-up ring Spielpassung also put in 150-200mm in sleeve pipe, the back-up ring left side arranges stuffing box, pressure ring is arranged between sleeve pipe and telescopic pipe in mode movingly and is positioned at the stuffing box left side, sleeve pipe left and right both ends of the surface are affixed with left flange and right flange respectively, telescopic pipe left side and telescopic pipe flange are affixed, pressure ring left side and pressure ring flange are affixed, the stud bolt left end arranges nut, after passing the bolt hole on the pressure ring flange, threadably with left flange on tapped hole link.
The beneficial effects of the utility model are: connect closely, be difficult for leaking, dilatability is large.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
