Description
Technical field
Mechanical seal category dynamic sealing, is widely used in the equipment such as various pumps, kettle, turbocompressor.
Background technology
Modern times sealing mainly has：Traditional packing seal, mechanical seal, pureed sealing, cartridge seal etc., wherein should
With being most widely mechanical seal, but mechanical seal also exposes many deficiencies in the application, and this sealing is mostly to rotate
Formula mechanical seal, spring is in sealing medium side, and performance is unstable and spring easily fails, although state type mechanical seal bullet
Spring mends Shang Huan also not in sealing medium side not in sealing medium side, generally, mends Shang Huan in sealing medium one
Side is more stable reliable.
The content of the invention
In view of the above circumstances, the invention provides one kind to mend Shang Huan in media side, and spring is not in sealing medium side
New rotating machanical seal.
The technical scheme is that：A set of rotating ring is housed, it is by rotating ring, rotating ring axle sleeve, rotating ring axle sleeve groove on axle sleeve
Mouth, notch baffle ring, sealing ring, notch bumping post and spring composition, rotating ring axle sleeve top is the rotating ring for being in side medium, rotating ring axle
Set middle and lower part is axially outwardly provided with four symmetrical long rabbets, and notch top is vertical four notch bumping posts, and notch bumping post is inserted into axle
Cover on jack, notch following is fixedly connected with notch baffle ring, and spring, the crown of spring one are housed between notch bumping post and notch baffle ring
Other end is withstood on notch baffle ring on notch bumping post, and two seal ring of moving ring, annular seal space are housed between rotating ring axle sleeve and axle sleeve
There is platform in the corresponding housing of middle rotating ring axle sleeve notch top, to position stationary ring, be located on platform equipped with stationary ring and stationary ring sealing ring, stationary ring
For rotating ring towards the side of notch baffle ring, notch, notch bumping post, spring, notch baffle ring on rotating ring axle sleeve are in non-side medium, groove
Mouth baffle ring drives rotating ring to compress stationary ring under the action of the spring, and to realize sealing, housing head end is equipped with gland.
Brief description of the drawings
Fig. 1 is structure sectional view of the present invention.
Fig. 2 is the A-A of structure sectional view of the present invention to sectional view.

There are four notch bumping posts 10, notch bumping post 10 is inserted on the jack of axle sleeve 1, and the following of notch 9 is fixedly connected with notch gear
Ring 11, is equipped with spring 12 between notch bumping post 10 and notch baffle ring 11, the crown of spring 12 1 is another on notch bumping post 10
One crown is equipped with two seal ring of moving ring 4,7 on notch baffle ring 11 between rotating ring axle sleeve 8 and axle sleeve 1, in annular seal space
There is platform in the top corresponding housing 2 of rotating ring axle sleeve notch 9, stationary ring 5 and stationary ring sealing ring 6 are housed, stationary ring 5 is positioned at dynamic on platform
Towards the side of notch baffle ring 11, notch 9, notch bumping post 10, spring 12, notch baffle ring 11 on rotating ring axle sleeve 8 are in ring 3
Non- side medium, notch baffle ring 11 drive rotating ring 3 to compress stationary ring 5 in the presence of spring 12, to realize sealing, housing 2
Head end is equipped with gland 13.
