Abstract
The utility model discloses a corrugated pipe sealing device, comprising a shaft sleeve, a movable ring, a fixed ring arranged at one end of the movable ring, a corrugated pipe arranged at the other end of the movable ring, a spring base, a spring, a transmission sleeve mounted at the outer side of the movable ring, and a clamping ring and a stopping cushion which are mounted at the outer side of the corrugated pipe. One end of the spring is sleeved on the clamping ring and the other end of the spring is sleeved on the spring base and is clamped with the spring base. According to the corrugated pipe sealing device disclosed by the utility model, a torque is commonly transmitted by the spring and the corrugated pipe, so that a load of the corrugated pipe is reduced and the service life of the corrugated pipe is prolonged.
Description
Technical field
The utility model relates to a kind of mechanical seal device, relates in particular to a kind of bellow seal.
Background technique
Traditional mechanical seal device for rubber bellows mainly is made up of with the bellows that rotating ring and tightening seat connect respectively stationary ring, seal ring and two ends; Wherein, Bellows will be born the effect of sealing and transmitting torque, and the abominable operating conditions of complicated stressed and high temperature or low temperature makes bellows be easy to generate the creep of surrender; " mistake bullet " phenomenon that causes elastic force to descend makes seal failure.
Therefore, be necessary to provide a kind of bellow seal that solves the problems of the technologies described above.
The model utility content
The utility model technical problem to be solved is: a kind of bellows bellow seal in working life that improves is provided.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of bellow seal; It comprises: axle sleeve, rotating ring, the stationary ring that is arranged at rotating ring one end, the bellows that is arranged at the rotating ring the other end, spring seat, spring, the drive sleeve that is installed on the rotating ring outside, the snap ring that is installed on the bellows outside and retaining pad; One end of said spring is sheathed on the snap ring, the other end be sheathed on the spring seat and with spring seat fixing mutually.
As a kind of optimized technical scheme, pass through the Cock screw fixing between said spring seat and the axle sleeve.
As a kind of optimized technical scheme, said stationary ring is fixed on the pump housing through stop pin.
As a kind of optimized technical scheme, an end of said spring is provided with bending part, and said drive sleeve is provided with the draw-in groove that matches with bending part.
The beneficial effect of the utility model is: the end through spring is sheathed on the snap ring, the other end be sheathed on the spring seat and with spring seat fixing mutually, thereby make spring can with the common transmitting torque of bellows, alleviate the burden of bellows, the life-span of improving bellows.

Fig. 2 is the structural representation of spring.
Among Fig. 1 to Fig. 2: 1, axle sleeve, 10, stop pin, 100, bellow seal, 2, rotating ring, 3, stationary ring, 30, the stationary ring seal ring, 4, bellows, 5, spring seat, 6, spring, 60, bending part, 7, drive sleeve, 8, snap ring, 9, the retaining pad.
Embodiment
See also Fig. 1 and Fig. 2; A kind of bellow seal 100; It comprises: axle sleeve 1, rotating ring 2, the stationary ring 3 that is arranged at rotating ring 2 one ends, the bellows 4 that is arranged at rotating ring 2 the other ends, spring seat 5, spring 6, the drive sleeve 7 that is installed on rotating ring 2 outsides, the snap ring 8 that is installed on bellows 4 outsides and retaining pad 9; One end of said spring 6 is sheathed on the snap ring 8, the other end be sheathed on the spring seat 5 and with spring seat 5 fixing mutually, but so spring 6 transmitting torques.One end of said spring 6 is provided with bending part 60, and said drive sleeve 7 is provided with the draw-in groove (not shown) that matches with bending part 60.Pass through the Cock screw fixing between said spring seat 5 and the axle sleeve 1.Said stationary ring 3 is fixed on the pump housing through stop pin 10.Also be provided with stationary ring seal ring 30 between the said stationary ring 3 and the pump housing; Right flank that said rotating ring sealing surface is a rotating ring 2 and stationary ring sealing surface are that the left side of stationary ring 3 is close together under the elastic force effect of spring 6; Said bellows 4 can play the effect of buffering, sealing and transmitting torque, but said spring 6 transmitting torque also when end thrust is provided.
The utility model is sheathed on the snap ring 8 through an end of spring 6, the other end be sheathed on the spring seat 5 and with spring seat 5 fixing mutually, thereby make spring 6 can with bellows 4 common transmitting torques, alleviate the burden of bellows 4, the life-span of improving bellows 4.
