CN2314215Y - Corrugated compensator with sealing device - Google Patents

Abstract

The utility model relates to a corrugated compensator with a sealing device, which comprises an outer cover, a corrugated pipe arranged in the outer cover, an inner flow guide sleeve of a corrugated pipe, an end flange and an end pipe, wherein a sliding sleeve sheathed at the periphery of the end pipe is fixed at the end of the outer cover. Ring-shaped sealing bodies are respectively clamped on the end pipe and the sliding sleeve through fastening clamps. The utility model has the advantages of simple structure and easy operation. Corrosive media in the atmosphere and soil can be effectively isolated, and the anti-corrosive capacity and the service life can be obviously improved.

Description

The FlexbleJoint that has seal arrangement

The utility model relates to the compensation device that a kind of pipe-line system or pipe network are used, particularly a kind of FlexbleJoint that has seal arrangement.

At present, every place that pipeline is arranged, in pipe-line systems such as metallurgy, petrochemical industry, thermoelectricity, heating, water supply, gas installation or pipe network, compensator has become its indispensable compensating element.Traditional compensator has " Jiong " shape tension force joint, stuffing box expansion joint.The former compensation ability is little, and volume is big, has increased the installation occupation space; The latter mainly relies on the stuffing box packing sealing, and its sealability is relatively poor, easily leaks, and should not work under the higher temperature operating mode.These two kinds of compensating element poor flexibility require highly to installation precision, if bad to neutrality when installing, then can produce very big Installation Stress, cause pipeline break or leakage.At above-mentioned shortcoming, now begun to adopt bellows device formation FlexbleJoint by way of compensation, this advanced person's pipeline compensator has overcome many defectives that prior art exists, and has tangible advantage.Therefore, FlexbleJoint has obtained wide popularization and application.Existing FlexbleJoint can be processed into various structural types according to the applying working condition difference.Owing to have the macro-corrosion medium in atmosphere, the soil, so for FlexbleJoint, no matter be at slurry blank pipe line, or direct buried pipeline, periphery is the contact corrosion medium all, especially the core parts bellows that adopts stainless steel material to make has in the medium of corrosive action stainless steel at the higher medium of chloride ion content or other, is vulnerable to corrosion most.Serious corrosion can make FlexbleJoint lose efficacy.Because of in a single day FlexbleJoint installs, all do not allow frequent replacing, so strengthen the anti-corrosion protection of FlexbleJoint is seemed even more important.

The purpose of this utility model provides a kind of FlexbleJoint that has seal arrangement, its simple in structure, easy operation, and effectively the aggressive medium in separating atmospheric, the soil significantly improves its antiseptic power and working life.

The purpose of this utility model is achieved in that this device comprises overcoat, assembles bellows in it and interior water conservancy diversion cover thereof, end flange, end pipe, the sliding sleeve that wherein is sleeved on end pipe periphery fixes on the overcoat end, and utilizes anchorage clip that annular sealing member is clamped in respectively on end pipe and the sliding sleeve.

Because the utility model is improved on the prior art constructions basis, so be easy to realize.This device adopts annular sealing member, be encapsulated in respectively on the sliding sleeve of end pipe, make the bellows that is assembled in the overcoat, aggressive medium by the annular sealing member and the compensator outside is isolated, thereby avoid the aggressive medium in atmosphere, the soil to enter in the overcoat by the gap between end pipe and the sliding sleeve, prevent the direct contact corrosion medium of bellows, significantly improve its antiseptic power and working life.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure schematic representation of the present utility model.

Describe concrete structure of the present utility model in detail according to Fig. 1.This device comprises parts such as overcoat 4, end pipe 1,10, end flange 2, bellows 3, overcoat 4, interior water conservancy diversion cover 5, black box, sliding sleeve 9.The bellows 3 that wherein is assembled in the overcoat 4 is fixed together with interior water conservancy diversion cover 5, end flange 2, outer tube 1,10.The sliding sleeve 9 that is sleeved on end pipe 10 peripheries is fixed on the overcoat end.Black box is made up of anchorage clip 6,8 and annular sealing member 7.Its annular sealing member 7 utilizes anchorage clip 6,8 to be clamped in respectively on end pipe 10 and the sliding sleeve 9, and bellows 3 is encapsulated in the overcoat 4, isolates with the aggressive medium in the compensator outside, reaches the purpose of protection bellows 3, thereby improves the working life of FlexbleJoint.The structural type of bellows 3 or select shapes such as U-shaped, Ω shape, S shape, V-arrangement according to designing requirement for use.Annular sealing member 7 can be selected corresponding anti-corrosion material for use according to operating modes such as the aggressive medium that is transferred, temperature, as teflon, rubber, leather etc.

Claims (1)

1, a kind of FlexbleJoint that has seal arrangement, comprise overcoat, assemble bellows in it and interior water conservancy diversion cover thereof, end flange, end pipe, it is characterized in that the sliding sleeve that is sleeved on end pipe periphery is fixed on the overcoat end, and utilize anchorage clip that annular sealing member is clamped in respectively on end pipe and the sliding sleeve.
