Description
Technical field
The utility model relates to stirrer technical field, especially a kind of stirrer with single mechanical end face seal.
Background technique
For making solid, liquids and gases forced convection Homogeneous phase mixing, or need to strengthen heat exchanging process, stirrer is indispensable in chemical industry, building industry, medical treatment and food etc. are produced.Mechanical seal is very part and parcel in stirrer, and traditional mechanical seal structure is complicated, and install and keep in repair cumbersome, cost is higher.
The mechanical seal of current stirrer, adopt fluorine rubber plain cushion to the static seal bottom stationary ring, the resiliently deformable due to fluorine rubber plain cushion makes the pretightening force of bolt evenly uncontrollable, thus makes two split ring body end surface dislocation and affect sealing.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of stirrer with single mechanical end face seal improving sealing.
The utility model solves the technological scheme that its technical problem adopts: a kind of stirrer with single mechanical end face seal, there is low pressure single mechanical end face seal, described low pressure single mechanical end face seal comprises drive bolt, spring seat, seal ring of moving ring, rotating ring, stationary ring, stationary ring pressing plate and stationary seat, described stationary ring is two isometrical graphite stationary rings splitting ring type, the place of splitting of graphite stationary ring has resistant to elevated temperatures quick-sealing glue-line, described graphite stationary ring is circular cone structure, and there is columniform endoporus, the bottom of graphite stationary ring is provided with the O RunddichtringO as static seal, described stationary seat is provided with lubrication basin.
The stationary ring of mechanical seal adopts graphite material, and lubricity is better; The graphite stationary ring place of splitting has resistant to elevated temperatures quick-sealing glue-line, can keep flexible and elasticity for a long time, and in the time not requirement of joint, sealing surface can bear work loads at once; The O RunddichtringO be provided with bottom graphite stationary ring, makes the bottom of graphite stationary ring contact with the good stationary seat of rigidity completely, ensure that the parallelism of graphite stationary ring both ends of the surface, and the radial and axial uniform force of graphite stationary ring, improves sealing effect simultaneously.
Further, the hold-down ring that tapering peripheral with it is wanted to mate is provided with outside graphite stationary ring.Utilize the restraining force of hold-down ring, the face of splitting of graphite stationary ring can be made to seal.
Further, the material of described rotating ring is the cobalt alloy of heat resistant and wear resistant.
The beneficial effects of the utility model are: the static seal in the utility model bottom graphite stationary ring changes O RunddichtringO into, eliminate original fluorine rubber plain cushion, the resiliently deformable that effectively prevent due to flat gasket makes two divided ring planes dislocation and leaks, O RunddichtringO makes the bottom of graphite stationary ring contact with the good stationary seat of rigidity completely, ensure that the parallelism of graphite stationary ring both ends of the surface, the radial and axial uniform force of graphite stationary ring, improves the sealing effect of mechanical seal simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. drive bolt, 2. spring seat, 3. seal ring of moving ring, 4. rotating ring, 5. graphite stationary ring, 6. stationary ring pressing plate, 7. stationary seat, 8.O RunddichtringO, 9. lubricates basin.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of stirrer with single mechanical end face seal, there is low pressure single mechanical end face seal, low pressure single mechanical end face seal comprises drive bolt 1, spring seat 2, seal ring of moving ring 3, rotating ring 4, stationary ring, stationary ring pressing plate 6 and stationary seat 7, the material of rotating ring 4 is the cobalt alloy of heat resistant and wear resistant, stationary ring is two isometrical graphite stationary rings 5 splitting ring type, the place of splitting of graphite stationary ring 5 has resistant to elevated temperatures quick-sealing glue-line, graphite stationary ring 5 is circular cone structure, and there is columniform endoporus, the bottom of graphite stationary ring 5 is provided with the O RunddichtringO 8 as static seal, the hold-down ring that tapering peripheral with it is wanted to mate is provided with outside graphite stationary ring 5, stationary seat 7 is provided with lubrication basin 9.
Must Sealing be changed when mechanical seal damages, in the present embodiment, only Sealing need be taken out, reload new Sealing, do not need to dismantle miscellaneous part, 1 ~ 2 skilled labour just can reach quick-replaceable effect in 10 minutes, has saved cost of production and labor intensity.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
