Abstract
The utility model relates to a moveable ring labyrinth sealing device, comprising moveable ring friction pair, a shaft sleeve, and a moveable ring bracing frame, an auxiliary sealing O-type ring is disposed between the moveable ring friction pair and the shaft sleeve, an additional O-type ring is also disposed between the moveable ring friction pair and the shaft sleeve, the moveable ring labyrinth sealing device in the utility model is advantageous in that since an additional O-type ring and an auxiliary sealing O-type ring are disposed between the moveable ring friction pair and the shaft sleeve, when the additional O-type ring is embedded, the additional O-type ring and the original auxiliary sealing O-type ring increase relative pressure between the moveable ring friction pair and the shaft sleeve, forming a labyrinth sealing and effectively isolating medium and flushing liquor.
Description
Technical field
The utility model relates to a kind of seal arrangement, especially relates to a kind of rotary ring labyrinth sealing device.
Background technique
The chemical machinery needle seal requires difference relatively to various distinct devices, and precision also requires more and more higher, requires mechanical seal to use to install from material-structure and more and more tends to fast and simple practicality.The existing material of what use is made of improves mechanical sealing performance, also can realize better economizing on the use of funds simultaneously, and being one has technical problem to be solved.
In addition, contain a large amount of chemical reaction impurity in the chemical industry mechanical seal rinsing liquid in order to overcome, effectively utilize existing rotating ring sealing, do not change itself structure, make sealing effect the best, avoid occurring leakage or gas leakage and enter in bearing housing or the atmosphere environment, harm Environmental security and people's life safety.
The model utility content
The utility model has designed a kind of rotary ring labyrinth sealing device, and it has solved under the macrostructure that does not change existing seal arrangement, changes the not good technical problem of rotating ring sealing effect.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of rotary ring labyrinth sealing device comprises rotating ring friction pair, axle sleeve and rotating ring supporting frame, is provided with an auxiliary seal O type circle between described rotating ring friction pair and axle sleeve, also is provided with an additional O-ring between described rotating ring friction pair and axle sleeve.
Further, described auxiliary seal O type circle and additional O-ring are in contact with one another; And one of them contacts described auxiliary seal O type circle and additional O-ring with described rotating ring friction pair, and another one contacts with described axle sleeve.
Further, described auxiliary seal O type circle contacts with described rotating ring friction pair, and described additional O-ring contacts with described axle sleeve.
Wherein, the material of above-mentioned auxiliary seal O type circle and additional O-ring is not limit, as long as can play the effect of encryption, in general, often adopts the teflon material.
This rotary ring labyrinth sealing device is compared with traditional rotating ring seal arrangement, has following beneficial effect:
(1) the utility model is owing to be provided with additional O-ring and auxiliary seal O type circle between described rotating ring friction pair and axle sleeve, when additional O-ring embeds the back and former auxiliary seal O type circle increases relative pressure between rotating ring friction pair and axle sleeve, form one labyrinth seal and also can effectively completely cut off medium and washing solution.
(2) the utility model has been owing to adopted additional O-ring, thereby should additional O type figure can substitute the tetrafluoro circle of the anti-impurity of original use, and this additional O-ring in the effect that plays excellent sealing simultaneously, also can play anti-impurity purpose.
Description of drawings
Fig. 1: the sectional view of the utility model rotary ring labyrinth sealing device.
Description of reference numerals: O type circle material is the bag tetrafluoro
1-rotating ring friction pair; 2-auxiliary seal O type circle; The 3-additional O-ring; The 4-axle sleeve; 5-rotating ring supporting frame.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further:
A kind of rotary ring labyrinth sealing device comprises rotating ring friction pair 1, axle sleeve 4 and rotating ring supporting frame 5, is provided with an auxiliary seal O type circle 2 between described rotating ring friction pair 1 and axle sleeve 4, also is provided with an additional O-ring 3 between described rotating ring friction pair 1 and axle sleeve 4.
Described auxiliary seal O type circle 2 and additional O type Fig. 3 are in contact with one another; And one of them contacts described auxiliary seal O type circle 2 and additional O-ring 3 with described rotating ring friction pair 1, and another one contacts with described axle sleeve 4.
Specifically, can be that described auxiliary seal O type circle 2 contacts with described rotating ring friction pair 1, described additional O-ring 3 contacts with described axle sleeve 4.The utility model is owing to be provided with additional O-ring 3 and auxiliary seal O type circle 2 between described rotating ring friction pair 1 and axle sleeve 4, when additional O-ring 3 embeds the back and former auxiliary seal O type circle 2 increases relative pressure between rotating ring friction pair 1 and axle sleeve 4, form one labyrinth seal and also can effectively completely cut off medium and washing solution.
In addition, this additional O-ring 3 can substitute the tetrafluoro circle of the anti-impurity of original use, and this additional O-ring 3 in the effect that plays excellent sealing simultaneously, also can play anti-impurity purpose.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
