Abstract
A large-diameter sealing device for jointing mental ripple pipe machine is provided. A stationary ring is provided between a flange base and a shaft. A sealing loop is provided inside the clearance between the stationary ring and the flange base. A dynamic ring is arranged between a dynamic annulus base and the shaft. The dynamic ring is near the stationary ring and a ripple pipe is positioned between a spring base and the dynamic annulus base. On the spring base is provided with an adjusting bolt and a sealing ring. The ripple pipe is welded as round ring by alloy plate and compressed into arc-shaped wave blade and completed its casting via jointing. The maximum ripple of this device can reach Phi 1300mm with better sealing performance.
Description
Technical field
The utility model relates to a kind of major diameter welded metal-bellows mechanical seal device, belongs to the technical field of mechanical seal device.
Background technique
Welded metal-bellows mechanical seal is widely used in the every field of industry.It has floatability and well reaches the reliable sealing characteristics, it is pressed into the cross section with high strength alloy sheet material is the arc wave plate, be welded into bellows again, but owing to be subjected to the restriction of sheet material width, can only make the bellows of φ 300mm at present, when main equipment requires diameter at φ 300-φ 1300mm, be difficult to make with regard to the restriction that is subjected to technology, therefore do not satisfy needs and demand improvement urgently.
Summary of the invention
The purpose of this utility model is that a kind of major diameter welded metal-bellows mechanical seal device will be provided, it adopts special technology that heavy alloyed sheet material is pressed into wave plate, be welded into bellows again, its unsteady performance is good, sealability is reliable, and overall dimensions can be made into Φ 1300mm, is fit to the needs of main equipment.
Between the shell of major diameter welded metal-bellows mechanical seal device and the flange seat O RunddichtringO is arranged, shell 2 right-hand members of axle 1 match with flange seat 3, O type seal ring 4 is housed therebetween, between flange seat 3 and the axle 1 stationary ring 5 is housed, in the space between stationary ring 5 and the flange seat 3 seal ring 6 is housed, rotating ring 7 is contained between rotating seat 8 and the axle 1, and rotating ring 7 is adjacent with stationary ring 5, between spring seat 9 and the rotating seat 8 bellows 10 is housed, spring seat 9 is equipped with adjusts bolt 11 and seal ring 12.
Bellows is made with special process, and sheet metal welding is circular, is welded into bellows again after being pressed into the arc wave plate, and its internal diameter maximum can be φ 1300mm.
