Abstract

The invention provides a sleeve type compensator, and relates to the technical field of compensating devices of thermal fluid pipelines. A body pipe is coaxially connected to the outer wall of the rear half segment of a telescopic pipe of the compensator in a sleeved mode, a gland is tightly connected between the front end of the body pipe and the outer wall of the telescopic pipe in a sleeved mode, a plurality of sealing parts are tightly arranged on the rear side of the gland, a first check ring is tightly arranged on the rear sides of the sealing parts, a first supported flange is tightly connected to the outer wall of the front end of the gland in a sleeved mode, a second supported flange is tightly connected to the outer wall of the front end of the body pipe in a sleeved mode, the first supported flange and the second supported flange are fixedly connected through a plurality of sets of bolts, nuts and flat gaskets, a second check ring is welded to the outer wall of the rear end of the telescopic pipe, and a bushing ring is welded to the inner wall of the rear end of the body pipe. The sleeve type compensator has the advantages of being large in compensation amount, convenient to maintain, high in safety performance, long in service life, wide in using range, low in constructing cost of projects, wide in market prospect and extremely high in research and design value.

Description

Technical field: [0001] The invention relates to the technical field of compensation devices for thermal fluid pipelines, in particular to a novel sleeve-type compensator. Background technique:, [0002] Sleeve compensator, also known as tubular expansion joint, is a compensation device for thermal fluid pipelines. It is mainly used for axial thermal expansion and displacement absorption compensation after the auxiliary installation of straight pipelines. Or a compensator in a multi-directional fluid pipeline. Sleeve compensator is widely used in pipelines in urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries. It is suitable for hot water, steam, and oil media. The engineering pressure of the medium is ≤2.5Mpa, and the medium temperature is -40 ℃~600℃. [0003] The sliding surface of the sleeve compensator is specially treated, and it has good corrosion resistance in salt water, salt solution and other environments, which ...
