Abstract
The utility model discloses a directional high temperature and high pressure movement sealing device, and relates to the technical field of movement sealing. The directional high temperature and high pressure movement sealing device comprises a supporting frame and a sealing body, wherein the supporting frame has a circular ring structure; the sealing body has a sealed annular structure formed by at least two circular arc-shaped sealing blocks; and the sealing body is positioned on the inner side of the supporting frame, and the end of a radial tightening mechanism arranged on the periphery of the supporting frame is in contact with the outer wall of the sealing body. The directional high temperature and high pressure movement sealing device has the advantages that because the sealing body has the sealed annular structure formed by at least two circular arc-shaped sealing blocks, a moving body is enclosed to a large extend in an all-around way, no gap and dead corner exist, and the sealing body achieves a sealing effect; and meanwhile, according to an abrasion direction, the sealing body can be tightened through the radial tightening mechanism, an abraded part can be directionally repaired, service life is prolonged, shut-down times of equipment are reduced, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of motion technical field of sealing technology.
Background technique
The world today is in the sealing of High Temperature High Pressure moving element, generally all be to wrap moving body or packing enwinds moving body with flexible sealing ring, then use gland compression seal ring or packing, perhaps press a sealing ring pad between moving element and meront, play the purpose of sealing.In use, moving body wearing and tearing Sealing often is not overall wear, but a part, in other words conj.or perhaps eccentric wear, fray just begin to leak, because gland is one, only has whole tight ability good seal, and the abrading section can't increase, because of seal ring and packing can't do very large, so use several times, just need change seal ring or packing in very short time, and need stop equipment and time cooling because of High Temperature High Pressure when changing, and this just causes very large waste, and manufacturing efficiency is low.
The model utility content
The technical problems to be solved in the utility model provides a kind of directed High Temperature High Pressure motion seal arrangement, by adopting directed compaction techniques means, according to the directed fastening piece that compresses correspondence direction of seal abrasion condition, play seal action, and high temperature resistant, high pressure resistant, improve equipment operation efficient.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of directed High Temperature High Pressure motion seal arrangement, comprise supporting frame and seal, support frame as described above is circular ring, described seal is at least two closed circular structures that circular-arc sealing block forms, described seal is positioned at the radially retention mechanism end that arranges on supporting frame inboard and the supporting frame circumference and contacts with the seal outer wall, and described circular-arc sealing block is Cuprum alloy.
The corresponding at least retention mechanism radially of described every circular-arc sealing block.
It is characterized in that: be provided with side plate around the support frame as described above.
Described radially retention mechanism is bolt, bolt and the supporting frame screw-thread fit that radially arranges.
Described radially retention mechanism is electric pushrod or oil hydraulic cylinder.
The beneficial effects of the utility model are as follows: because seal adopts at least two arc sealing blocks to form closed circular ring-type structure, and the comprehensive moving body that encases of maximum area, seal action is played at seamless dead angle; According to the wearing and tearing orientation, can pass through radially retention mechanism fit sealing body simultaneously, the directed abrading section that replenishes increases the service life, and reduces the equipment downtime number of times, enhances productivity.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is that the utility model uses view;
In the accompanying drawings: 1, moving body; 2, the first moving body supports; 3, fixed body; 4, lubrication system; 5, retention mechanism radially; 6, side plate; 7, seal; 8, the second moving body supports.
Embodiment
In sum, the utility model discloses a kind of directed High Temperature High Pressure motion seal arrangement (referring to accompanying drawing 1), comprise supporting frame and seal 7, support frame as described above is circular ring, described seal 7 is at least two closed circular structures that circular-arc sealing block forms, and described seal 7 is positioned at radially retention mechanism 5 ends that arrange on supporting frame inboard and the supporting frame circumference and contacts with seal 7 outer walls.The purpose of seal 7 subsection setups is to compensate according to its different parts abrasion condition, plays the effect that increases the service life, and also can prolong the repair cycle; Seal 7 is in normal using process; its inwall and moving body 1 fit tightly; but because discontinuity produces uneven wear to seal 7 in moving body 1 operation process; existing seal arrangement can only be whole fastening; to increase the frictional force of the less position of wearing and tearing and moving body 1 in the whole fastening process; and seal is short 7 working lifes; the seal 7 that uses under high temperature and high pressure environment needs frequent; the serious manufacturing efficiency that reduces; and local orientation's compensation technique means that the utility model adopts; circular-arc sealing block adopts Cuprum alloy; only need local fit sealing piece can realize compensation, need not integrated pressure tightening seal body 7, and need not in the fastening process to shut down; enhance productivity, prolong 7 working lifes of seal.
The corresponding at least retention mechanism 5 radially of described every circular-arc sealing block, every sealing block can correspondence arranges one or two or more radially retention mechanism, its purpose is radial compaction seal 7, makes its abrasion condition according to seal 7 carry out the part and compresses compensation.
Be provided with side plate 6 around the support frame as described above, supporting frame is the circular ring of sealing, its role is to seal 7 is put in the inner, and come press seal body 7 by the radially retention mechanism 5 that arranges on its circumference, play a supportive role, side plate 6 is set around it simultaneously is used for it is fixedly connected with fixed body 3, its structure can design relatively according to distinct device certainly.
Described radially retention mechanism 5 is the bolt that radially arranges, bolt and supporting frame screw-thread fit, and in concrete application process, the main needs gets final product inside press seal body 7 with the bolt of the fastening leakage point corresponding position of spanner, plays seal action.Described radially retention mechanism 5 is electric pushrod or oil hydraulic cylinder, if adopt electric pushrod or oil hydraulic cylinder, then needs to use solenoid valve and control circuit, and control circuit can design according to the quantity of electric pushrod or oil hydraulic cylinder.
More in addition, the axle that said moving body 1 is running shaft or axial motion in the utility model, the 2 and second motion support 8 is supported in the first motion that is provided for supporting movement body 1 on the fixed body 3, it can be sliding bearing that the 2 and second motion support 8 is supported in the first motion, at fixed body lubrication system 4 is set simultaneously and provides lubricant oil for the first motion support the 2 and second motion support 8, and the utility model is applicable to High Temperature High Pressure and corrosion-resistant environment.
