This utility model is further arranged to：Described stationary ring is silicon carbide material, and described rotating ring is Furan filled carbon Material.

By adopting technique scheme, carborundum stable chemical performance, heat conductivity is high, and anti-wear performance is good, thus During use, abrasion is little, and heat can distribute in time it is ensured that normal work；Furan filled carbon resistance to chemical attack, self-lubricating simultaneously Performance is good, can be friction sealed with carborundum stationary ring without lubricating oil, wear-resistant, long service life.

This utility model is further arranged to：Described rotating ring is provided with nitrile rubber sealing ring towards throw-out collar side.

By adopting technique scheme, nitrile rubber has good oil resistant and anti-wear performance, friction when rotating ring rotates Power is larger, can guarantee that sealing ring has sufficiently high service life using nitrile rubber, simultaneously nitrile rubber resistance to water and airtight Property is good, has good sealing effectiveness.

This utility model is further arranged to：The annulus that described stationary ring is provided with receiving rotating ring top towards rotating ring side is recessed Groove.

By adopting technique scheme, the rectilinear slot between rotating ring and stationary ring is replaced with fold-line-shaped, thus rotating ring Sealing area is bigger and stationary ring between, simultaneously the sealing surface of fold-line-shaped, and gas-liquid, by needing to turn to, by difficulty, seals Performance is more preferable.

This utility model is further arranged to：Described ring groove bottom opens up some radiatings with the conducting of stationary ring outer wall Hole.

By adopting technique scheme, the setting of louvre ensure that the heat energy of the generation that rubs between stationary ring and rotating ring Enough distribute in time, improve the heat dispersion between stationary ring and rotating ring, it is to avoid temperature raises impact structure.

This utility model is further arranged to：Described throw-out collar is provided with fixed column towards spring one end, and described fixed column is worn Cross spring center and conflict with spring.

By adopting technique scheme, the setting of fixed column improves the induced effect to throw-out collar for the spring, increases bullet Contact area between spring and throw-out collar structure, thus ensure that during startup, spring has enough active forces to throw-out collar, it is to avoid bullet Spring be distorted deformation it is ensured that mechanical sealing member structure firm.

In sum, this utility model has the advantages that：

1st, rotating ring is fixed on by retainer using collar, mechanical sealing member is divided into two sections, simplify the peace of mechanical sealing member Dress；

2nd, adopt multiple little springs, improve elastic force, so that less, the precision that mechanical sealing member size can be done Higher；

3rd, rotatory sealing by the way of ring groove and rotating ring are conflicted, improves sealing property, louvre can in time by Heat distributes.
