Description
Technical field
The utility model relates to pipeline compensator technical field, especially a kind of abrasionproof expansion joint being provided with flexible dustproof structure.
Background technology
Existing expansion joint for pipeline is also known as pipeline compensator, and expansion joint for pipeline has ball-type expansion joint and bellows expansion joint usually.Expansion joint can do axial direct displacement of the lines and radial angle displacement, the displacement produced when equipment such as energy effective compensation and absorption boiler etc. runs.The bellows expansion joint that existing coal-burning power plant installs is generally for pulverized coal channel design, and the environment for use of pulverized coal channel expansion joint is comparatively severe, and solid particle and dust a lot, and need larger flexible compensation amount.
Existing bellows expansion joint generally comprises bellows and is located at the left and right adapter at bellows two ends, and the inside of bellows is provided with guide shell, and the inwall of guide shell one end and left adapter is welded and fixed, and the other end is near right adapter and form gap with its inner surface.Such bellows expansion joint in use, having dust enters between bellows and guide shell from gap, because expansion joint in use constantly can produce expanding-contracting action, solid dust can produce abrasive action to expansion joint, during such use one section, after date expansion joint is just easily worn and leakage phenomenon occurs, thus must change expansion joint, causes the service life of compensator short, safeguard and change workload greatly, cost is high.
Utility model content
The purpose of this utility model is to provide a kind of abrasionproof expansion joint being provided with flexible dustproof structure; gap between guide shell and adapter inner surface is provided with dustproof construction; solid particle and dust can be stoped to enter in gap, thus available protecting expansion joint, extend its service life.
The purpose of this utility model is achieved by the following technical solution:
Be provided with the abrasionproof expansion joint of flexible dustproof structure, comprise bellows and be located at the left adapter at bellows two ends and right adapter respectively, the inside of bellows is provided with guide shell, one end of guide shell and the inwall of left adapter are welded and fixed, the other end is near right adapter and form gap from a distance with its inner surface, and described guide shell is provided with dustproof construction near between the end of right adapter and right adapter inner surface.
As optimal technical scheme of the present utility model, described dustproof construction comprises the dust ring be made up of flexible material, or the Air Filter be made up of elastic metallic material.
As optimal technical scheme of the present utility model, described dustproof construction to be connected with guide shell or right adapter by support and to fix.
As optimal technical scheme of the present utility model, described support is set to herringbone structure, and the outer surface of support and guide shell is welded and fixed.
As optimal technical scheme of the present utility model, the outer surface of described left adapter and right adapter is welded with otic placode respectively, is connected between two otic placodes by screw rod with nut.
As optimal technical scheme of the present utility model, the end of described left adapter and right adapter is respectively equipped with flange, and flange has connecting hole.
The beneficial effects of the utility model are: relative to prior art; the utility model arranges dustproof construction in the gap between expansion joint guide shell and adapter inner surface; solid particle and dust can be stoped to enter in described gap; thus avoid the harmful grinding in the expansion joint course of work; available protecting expansion joint, extends its service life.
