Abstract

The utility model discloses a mechanical sealing device for high pressure glass lining kettles. The motion ring and static ring at the end of the air and the motion ring and static ring at the end of the medium are positioned vertically. The motion ring and static ring at the end of the medium is beneath the motion ring and static ring at the end of the air. The motion ring at the end of the air and the motion ring at the end of the medium are connected to the upside and downside of the transmission base respectively, wherein a first and a second buffing spring are arranged respectively on the upside and downside. The vertical arrangement of the motion ring and static ring at the end of the air and the end of the medium can relieve the pressure in the kettle, and the vertical arrangement of the first and the second buffing spring can countervail partial pressure from each other, which can reduce the pressure on the shaft sleeve. Therefore, the embodiment can prevent the shaft sleeve and the shafts from loosening.

Description

High-pressure Glass Lining Kettle Uses Mechanical Seal Device

Technical field

The utility model relates to a kind of mechanical seal device, especially a kind of High-pressure Glass Lining Kettle Uses Mechanical Seal Device.

Background technique

At present, in High-pressure Glass Lining Kettle Uses Mechanical Seal Device, being radially (level) between dynamic and static ring of atmosphere end and the dynamic and static ring of media end is provided with, be difficult to dissolve the pressure in the next still like this, axle sleeve will be subjected to the pressure of three aspects, one is that pressure medium, two is that sealing liquid pressure, three is spring force, makes axle sleeve that one bigger upwards lifting force be arranged, and so long-term use rear axle housing and between centers are easy to get loose.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of High-pressure Glass Lining Kettle Uses Mechanical Seal Device, can effectively keep axle sleeve and between centers to be not easy to get loose after the long-term use of this High-pressure Glass Lining Kettle Uses Mechanical Seal Device.

The utility model for the technological scheme that solves its technical problem and adopt is: a kind of High-pressure Glass Lining Kettle Uses Mechanical Seal Device, comprise the atmosphere end rotating ring, the atmosphere end stationary ring, the media end rotating ring, the media end stationary ring, and be fixed on the retainer of axle sleeve, atmosphere end is moving, stationary ring and media end are moving, be vertical setting between the stationary ring, media end is moving, it is moving that stationary ring is in atmosphere end, under the stationary ring, the atmosphere end rotating ring, the media end rotating ring respectively spline be connected in retainer on, below, the atmosphere end rotating ring, the media end rotating ring respectively with retainer on, below between be provided with first, two damping springs.

The beneficial effects of the utility model are: be vertical setting between dynamic and static ring of atmosphere end and the dynamic and static ring of media end, can finely dissolve the pressure in the next still, medium and media end rotating ring surface of contact reduce, the media end rotating ring can significantly reduce suffered pressure medium like this, thereby reduce the axle sleeve pressure, first and second damping spring is the partial pressure of can cancelling out each other so vertically is set again, can further reduce the axle sleeve pressure, therefore after long-term the use, this example still can effectively keep axle sleeve and between centers to be not easy to get loose.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a schematic representation of the present utility model.

Embodiment

Embodiment: referring to Fig. 1, a kind of High-pressure Glass Lining Kettle Uses Mechanical Seal Device, comprise atmosphere end rotating ring 11, atmosphere end stationary ring 12, media end rotating ring 21, media end stationary ring 22, and be fixed on the retainer 4 of axle sleeve 3, atmosphere end is moving, stationary ring and media end are moving, be vertical setting between the stationary ring, media end is moving, it is moving that stationary ring is in atmosphere end, under the stationary ring, the atmosphere end rotating ring, the media end rotating ring respectively spline be connected in retainer on, below, the atmosphere end rotating ring, the media end rotating ring respectively with retainer on, below between be provided with first, two

damping springs

51,52, can further reduce the suffered pressure of axle sleeve.

Be vertical setting between dynamic and static ring of atmosphere end and the dynamic and static ring of media end, can finely dissolve the pressure in the next still, medium and media end rotating ring surface of contact reduce, the media end rotating ring can significantly reduce suffered pressure medium like this, thereby reduce the axle sleeve pressure, first and second damping spring is the partial pressure of can cancelling out each other so vertically is set again, can further reduce the axle sleeve pressure, and sealing liquid greatly reduces the axle sleeve upward pressure in this example again.Therefore can effectively keep axle sleeve and between centers to be not easy to get loose after long-term the use.

Again in this example, still mouth flange contacts the inboard with the axle motive sealing and is coated with polytetrafluoroethylene gasket 6, packing ring extends coating to the flange above and below simultaneously, described gasket thickness is more than or equal to five millimeters, the good anti-corrosive properties of polytetrafluoroethylene gasket tool, so still mouth flange and between centers can keep good sealing property for a long time.

Claims

1. High-pressure Glass Lining Kettle Uses Mechanical Seal Device, comprise atmosphere end rotating ring, atmosphere end stationary ring, media end rotating ring, media end stationary ring and be fixed on the retainer of axle sleeve, it is characterized in that: be vertical setting between dynamic and static ring of atmosphere end and the dynamic and static ring of media end, the dynamic and static ring of media end be in the dynamic and static ring of atmosphere end under, atmosphere end rotating ring, media end rotating ring spline respectively are connected in the above and below of retainer, and atmosphere end rotating ring, media end rotating ring are respectively and be provided with first and second damping spring between the above and below of retainer.
