The utility model discloses an inner skleeve, outer sleeve, set up the seal assembly between the radial clearance of outer sleeve and inner skleeve, the utility model discloses a be equipped with protective assembly between inner skleeve free end and the outer sleeve, form airtight cavity between protective assembly and the inner skleeve, thereby avoid the inner skleeve free end to produce corrosion phenomenon through the intussuseption in airtight cavity to be filled with inert gas. The utility model discloses simple structure is fit for using widely.
Description
Technical Field
The utility model relates to a compensator field, concretely relates to anticorrosive type one-way sleeve compensator.
Background
The traditional sleeve compensator has the remarkable characteristics of simple structure, strong bearing capacity, large axial compensation capacity and the like, is called a tubular expansion joint, is a compensation device of a hot fluid pipeline, is mainly used for absorbing and compensating axial thermal expansion displacement generated after a linear pipeline is arranged in an auxiliary mode, is a compensator directly installed in any pipeline for conveying non-corrosive unidirectional or multidirectional fluid, is widely used in conveying pipelines of industries such as urban heating, metallurgy, mines, power generation, petrochemical industry, building and the like, and mainly comprises a sleeve (core pipe), a shell, a sealing material and the like.
At present, one end of a sleeve is fixed and the other end of the sleeve is free when the sleeve compensator is used, and the free end generates sliding friction when generating axial displacement, so that the surface is easy to generate serious corrosion after being exposed in the air after being damaged.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an anticorrosive type one-way sleeve compensator.
The technical scheme of the utility model is that: the utility model provides an one-way sleeve compensator of anticorrosive type, including the inner skleeve, the one end of inner skleeve is the free end, the other end outside is equipped with the outer sleeve, be provided with seal assembly between the radial clearance of outer sleeve and inner skleeve, seal assembly passes through bolt fixed connection with the outer sleeve, the other end of outer sleeve is through end union coupling to flange, make the inner skleeve realize the slip compensation in seal assembly, be equipped with protection component between inner skleeve free end and the outer sleeve, protection component includes retractable protection casing and gasbag, the retractable protection casing passes through the pipeline and the gasbag intercommunication, the one end of retractable protection casing is fixed at the inner skleeve free end, the other end is fixed in the outer sleeve and is connected one end with seal assembly, retractable protection casing.
According to a further technical scheme, the sealing assembly comprises a packing gland and sealing packing, and the sealing packing is filled in a radial gap between the outer sleeve and the inner sleeve through the packing gland fixed on the outer sleeve.
In a further technical scheme, the inert gas is nitrogen.
According to a further technical scheme, the sealing filler comprises a flexible graphite packing, fluorine rubber and silicone oil.
The utility model has the advantages that:
the utility model discloses to the serious problem of corrosion phenomenon that one-way sleeve free end leads to because the slip damage among the prior art, through being equipped with protective assembly between inner sleeve free end and the outer sleeve, form airtight cavity between protective assembly and the inner skleeve, thereby airtight cavity intussuseption is filled with inert gas and avoids the inner skleeve free end to produce corrosion phenomenon, has prolonged one-way sleeve's life effectively.

Detailed Description
The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.
As shown in fig. 1, the utility model relates to an one-way sleeve compensator of anticorrosive type, including inner skleeve 1, the one end of inner skleeve 1 is the free end, and the other end outside is equipped with outer sleeve 3, is provided with seal assembly 2 between the radial clearance of outer sleeve 3 and inner skleeve 1, and the other end of outer sleeve 4 is connected to flange 5 through end joint pipe 4. The sealing assembly 2 comprises a packing gland 21 and a sealing packing 22, and the sealing packing 22 comprises a flexible graphite packing, fluorine rubber and silicone oil. The packing gland 21 is fixedly connected with the outer sleeve 4 through bolts, the sealing packing 22 is filled between the radial gaps of the outer sleeve 3 and the inner sleeve 1 through the packing gland 21, so that the inner sleeve 1 realizes sliding compensation in the sealing assembly 2,
be equipped with protection component 6 between 1 free end of inner skleeve and the outer sleeve 3, protection component 6 includes retractable protection casing 61 and gasbag 62, retractable protection casing 61 passes through the pipeline and communicates with gasbag 62, the one end of retractable protection casing 61 is fixed at 1 free end of inner skleeve, the other end is fixed in the outer sleeve 3 and is connected one end with seal assembly 2, form airtight cavity between retractable protection casing 61 and inner skleeve 1, the gasbag 62, airtight cavity intussuseption is filled with inert gas, like nitrogen gas etc.. The piston rod protective cover is made of high-temperature-resistant and corrosion-resistant materials, can stretch out and draw back along with the sliding of the free end, and redundant gas in the piston rod protective cover enters the air bag 62 to be stored. The free end of the inner sleeve 1 is ensured to be always protected by inert gas, and the surface of the free end of the inner sleeve 1 is prevented from being exposed to air and corroded due to abrasion caused by sliding.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
