Abstract
The invention discloses a double-end face mechanical seal, which includes a medium end seal and an atmosphere end seal, also includes a rotating shaft surrounded by the two seals and a flange plate disposed on the lower end of a main body; a static ring on the medium end is floatingly installed in the flange plate, sealing surfaces through which the static ring on the medium end is fitted into a movable ring on the medium end are parallel and attached. The seal disclosed by the invention achieves the advantages of good sealing property, no cooling jacket or bearing, no redundant additive to pollute the material, small size, convenient carrying, no need to be equipped with a frame in actual use and convenient operation.
Description
Technical field
The present invention relates to a kind of sealing device, be specifically related to a kind of double mechanical seal.
Background technology
At present, glassed steel reaction vessels is by the glass containing high silicon dioxide in the prior art, serves as a contrast
The inner surface of steel vessel, through high temperature sintering, adherence becomes composite wood on metal surface securely
Material products, it has stability and the two-fold advantage of metal strength of glass, is a kind of excellent resistance to
Etching apparatus, existing vesselseals is all with cooling jacket and bearing, in cooling jacket
Cold water to be passed through reach cooling effect, and bearing have to oil addition, the most organic
Meeting is to the material contamination in reactor, and this mechanical seal volume and weight are the biggest, side
Just carrying, in addition, existing mechanical seal needs additionally mounted frame time actually used, so
After reductor and motor are installed in frame, operation more bothers.
Summary of the invention
The invention aims to the deficiency overcoming prior art to exist, it is provided that a kind of Double End
Mechanical seal, it does not has cooling jacket and bearing, will not add unnecessary Substances Pollution material, and
The little convenient carrying of volume, need not time actually used additionally dispose frame, convenient operation.
For reaching above-mentioned purpose, technical scheme is as follows:
A kind of double mechanical seal, its main body is sealed to seal with atmosphere end by media end and forms, and
Including being sealed, by above-mentioned two, the rotating shaft surrounded and being located at the ring flange of main body lower end, it is characterised in that
Described media end seals and includes being located at rotating shaft lower end and the floating media end stationary ring being loaded in described ring flange
And it is located at the media end rotating ring above this stationary ring；Described atmosphere end seal include atmosphere end stationary ring and
Atmosphere end rotating ring, the middle part that described atmosphere end stationary ring and atmosphere end rotating ring are located at described rotating shaft is peripheral,
And stationary ring is placed in the top of rotating ring, the lower end of rotating ring connects a spring.
Preferably, described media end rotating ring, media end stationary ring, atmosphere end rotating ring and atmosphere end are quiet
O all it is arranged with outside ring.
Preferably, described double mechanical seal side is provided with leak from top to bottom, cooling water goes out
Mouth and sealingfluid inlet, opposite side is provided with oil filling mouth, seal fluid outlet from top to bottom with cold
But water inlet.
The invention discloses a kind of double mechanical seal, media end seal and atmosphere end sealing group
Become, and include being sealed, by above-mentioned two, the rotating shaft surrounded and being located at the ring flange of main body lower end, medium
End stationary ring is floating to be loaded in ring flange, enables stationary ring to fit to the sealing surface of rotating ring is parallel to each other, tool
There is good sealing, and there is no cooling jacket and bearing, unnecessary Substances Pollution material will not be added
Material, the little convenient carrying of volume, need not time actually used additionally dispose frame, convenient operation.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, embodiment will be retouched below
In stating, the required accompanying drawing used is briefly described.

Side of the present invention is provided with leak F, coolant outlet D and sealingfluid inlet A from top to bottom,
Opposite side is provided with oil filling mouth E, seal fluid outlet B and cooling water inlet C from top to bottom.
The invention discloses a kind of double mechanical seal, media end seal and atmosphere end sealing group
Become, and include being sealed, by above-mentioned two, the rotating shaft surrounded and being located at the ring flange of main body lower end, medium
End stationary ring is floating to be loaded in ring flange, enables stationary ring to fit to the sealing surface of rotating ring is parallel to each other, tool
There is good sealing, and there is no cooling jacket and bearing, unnecessary Substances Pollution material will not be added
Material, the little convenient carrying of volume, need not time actually used additionally dispose frame, convenient operation.
It is more than the description to a kind of double mechanical seal embodiment proposed by the invention, to this
The multiple amendment of a little embodiments will be apparent from for those skilled in the art, this
