Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing to the present invention into
Row detailed description, the description of this part be only it is exemplary and explanatory, should not have any limitation to protection scope of the present invention
Effect.
As shown in Figure 1-Figure 3, specific structure of the invention are as follows: a kind of adjustable type integrated mechanical sealing, it includes sealing
Body 1, mechanical seal cover 2, positioning checkpoint 3, fixing screws 4, stop screw 5, axle sleeve 7, holding screw 9, positioning ring 10, stationary ring
11, rotating ring 12, jacking screw 14;The axle sleeve 7 is arranged on axis 6, the stationary ring 11, the setting of rotating ring 12 by 7 lower end of axle sleeve,
In cavity composed by seal 1 and mechanical seal cover 2;The stationary ring 11 is fixed at mechanical seal cover 2 and axle sleeve 7
Between, the rotating ring 12 is arranged in 11 lower end of stationary ring;7 upper end of axle sleeve is provided with positioning ring 10, sets on the positioning ring 10
It is equipped with holding screw 9, stop screw 5 and fixing screws 4;The fixing screws 4 are for installing positioning checkpoint 3, the positioning card
Son 3 is for being fixed at mechanical seal cover 2 for positioning ring 10;It is provided on the positioning ring 10 mechanical close for adjusting
The jacking screw 14 of gap B between sealed cover 2 and positioning ring 10.
As shown in Figs. 1-2, retaining ring 8 is provided on the axle sleeve 7, the retaining ring 8 is for limiting positioning ring 10 in axle sleeve 7
Mobile distance.
As shown in Figs. 1-2, gasket 13 is provided between the mechanical seal cover 2 and seal 1.
In order to further facilitate adjustment, extends the service life, be provided with cushion hole, the shape of the cushion hole on the rotating ring 12
