Abstract
The utility model relates to a high temperature rotary type pipeline compensator, which is developed and designed to overcome the shortcomings of the prior pipeline compensators. The high temperature rotary type pipeline compensator comprises a shaft I (1), a sleeve (2), a rotary sealing element (3), a shaft II (4), a spring (5), a gasket (6), a sealing element (7), and a cover plate (8). The rotary type pipeline compensator is characterized in that the shaft II (4) and the shaft I (1) are tightly attached through the rotary sealing element (3), the spring (5) is installed on the shaft (2), and the shaft II (4) and the shaft I (1) keep certain compacting force on the rotary sealing element (3) which is made from high-pure graphite under the push of the spring (5) all the time so as to automatically compensate the abrasion loss of the rotary sealing element in time. The gasket (6), the sealing element (7) and the cover plate (8) are used for limiting position to ensure the spring is pressed all the time; the arrangement of the sealing element (7) made from high-pure graphite enables rotation to be more flexible, and satisfies compensation of axial and peripheral dilatational deformation of the pipeline at the same time; and the adopted built-in spring arrangement can avoid reduction of service life due to chemical corrosion arising from the air, so as to reduce the use cost of manufacturers.
Description
Technical field:
The utility model relates to a kind of high-temperature pipe rotary compensator, is mainly used in the temperature compensation of the pipeline of industries such as electric power, metallurgy, oil, chemical industry.
Background technique:
In present piping design,, generally use pipeline compensator, to dissolve the security incident that causes because of the pipeline temperature distortion in order to satisfy the requirement of pipeline expanded by heating distortion.But this kind compensator only can satisfy the needs of pipeline axial distortion, and has ignored the circumferential distortion of pipeline, and use therein spring is exterior arrangement, and is as easy as rolling off a log because of aerochemistry corrosion inefficacy in advance, exists potential safety hazard to a great extent.
Summary of the invention:
The purpose of this utility model has provided a kind of high-temperature pipe rotary compensator, it promptly is at the existing defective of using now of pipeline compensator and development and Design, satisfy the axial and circumferential dilatancy compensation of pipeline simultaneously, the built-in spring configuration of being adopted can be avoided the chemical corrosion reduction of service life because of air, thereby has reduced the user cost of producer.
The technical program is: a kind of high-temperature pipe rotary compensator, it is made up of axle (I) 1, sleeve 2, rotating seal 3, axle (II) 4, spring 5, pad 6, Sealing 7, cover plate 8.It is characterized in that: axle (I) 1 is installed on the sleeve, sleeve 2 inner chamber polishings are processed, axle (I) 1 forms by welding with sleeve 2 and forever is connected, 1 of axle (II) 4 and spool (I) fit tightly with rotating seal 3, spring 5 is installed on the axle 2, under the promotion of spring 5, make axle (II) 4 and axle (I) 1 all the time the rotating seal of being made by high purity graphite 3 be kept certain impacting force, be rotated the compensation of the wear extent of Sealing in time, automatically.Between cover plate 8 and spring 5, be provided with pad 6 and Sealing 7, spacing with pad 6 Sealings 7 cover plates 8 to guarantee that spring compresses enduringly, existence owing to high purity graphite Sealing 7 simultaneously makes that rotation is more flexible, and sleeve 2 is connected with cover plate 8 usefulness bolts.
Description of drawings: Fig. 1 is the structural drawing of a kind of high-temperature pipe rotary compensator of the utility model.Wherein: axle (I) 1, sleeve 2, rotating seal 3, axle (II) 4, spring 5, pad 6, Sealing 7, cover plate 8
Embodiment:
With reference to accompanying drawing a kind of high-temperature pipe rotary compensator of the utility model is described further, it is made up of axle (I) 1, sleeve 2, rotating seal 3, axle (II) 4, spring 5, pad 6, Sealing 7, cover plate 8, it is characterized in that: described axle (I) 1 is installed on the sleeve 2, by welding together, axle (I) 1 and spool (II) 4 fit tightly by rotating seal, spring 5 is installed on the axle 2, sleeve 2 and cover plate 8 are connected by bolt, are provided with pad 6 and Sealing 7 between cover plate 8 and spring 5.
