Abstract
The utility model mainly relates to a rotary sealing device for transmission of a three-station isolating switch of the high-voltage switch equipment. The rotary sealing device comprises a flange and a rotating shaft. Bearings are respectively arranged at two ends in a central hole of the flange, and the rotating shaft supports in the central hole through the bearings; a sealing ring device is arranged between the bearings at two ends in the central hole; one side of the rotating shaft, penetrating out the flange, is an input end, and is fixed by a lock nut; and the other side of the rotating shaft, penetrating out the flange, is an output end, and is fixed by a ring-shaped step. The whole rotary sealing device is an independent unit, and is compact and simple in structure, reliable in rotary sealing, low in cost, convenient to detach, small in volume and convenient to detect.
Description
Technical field
The utility model relates generally to a kind of rotary sealing appts that is used for the transmission of high voltage switchgear tri-station isolating switch.
Background technology
Along with China's electric power and the manufacturing develop rapidly of switchgear, Direct Action Type isolating switch and tri-station isolating switch are at switch cubicle, and especially C-GIS inflation extensive use cashier's office in a shop makes rotary seal obtain using in a big way.
Because C-GIS inflation cabinet adopts the low-pressure airtight container, not too harsh to the requirement of sealing, but required that reliability is high, cost is low and focus that installation and measuring conveniently becomes technology for this reason to solve.Inflate the split-type structurals that use more at present cashier's office in a shop, can't become one separately, complex structure, volume is big, and cost is high, can not detect in advance, inconvenience is installed, poor reliability.
Summary of the invention
The utility model provides a kind of rotary seal to the problem that prior art exists, and reliability is high, and cost is low, and is for convenience detach, simple in structure, and volume is little, rotary sealing appts easy to detect.
To achieve these goals, the utility model patent adopts following technical scheme: a kind of rotary sealing appts, comprise flange, and rotating shaft, two ends are provided with bearing in the centre bore of described flange, and described rotating shaft passes through bearings in said centre bore; In centre bore, be provided with gasket set between the bearing at two ends; The side that rotating shaft passes flange is an input, and fixes through lock nut; The opposite side that rotating shaft passes flange is an output, and fixes through the torus step.
Further, described gasket set comprises at least one backbone sealing ring, between backbone sealing ring and bearing, is provided with at least one cage ring.
Further, on the flange disk body of said flange, be provided with sealing ring near the bead place of flange.
Further, on described input, be provided with input interface; On described output, be provided with output interface.
The beneficial effect of the utility model: whole rotary sealing appts is a unit independently, and compact conformation is simple, and rotary seal is reliable, and cost is low, and is for convenience detach, simple in structure, and volume is little, and is easy to detect.
Description of drawings:
Fig. 1: be the sectional structure sketch map of the utility model;
Fig. 2: be the perspective view of the utility model;
Fig. 3: be the user mode structural representation of the utility model;
Embodiment:
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
Embodiment 1: like Fig. 1, a kind of rotary sealing appts shown in Figure 2 comprises flange 3, rotating shaft 4, and two ends are provided with bearing 5 in the centre bore of described flange 3, and described rotating shaft 4 is supported in the said centre bore through bearing 5; In centre bore, be provided with gasket set between the bearing 5 at two ends; The side that rotating shaft 4 passes flange 3 is an input, and fixing through lock nut 2; The opposite side that rotating shaft 4 passes flange 3 is an output, and fixing through torus step 6.Described gasket set comprises a pair of backbone sealing ring 9, between backbone sealing ring 9 and bearing 5, is provided with a pair of cage ring 8.On the flange disk body of said flange 3, be provided with sealing ring 10 near the bead place of flange.On described input, be provided with input interface 1; On described output, be provided with output interface 7.
The practical implementation process of the utility model; As shown in Figure 3; A bearing 5 of location respectively is equipped with at flange 3 endoporus two ends; The centre is equipped with 8,2 reinforced seals 9 of a cage ring and a cage ring 8 successively, and rotating shaft 4 is above each part in adpting flange 3 endoporus vertically, and the step on it 6 and its lock nut 2 that goes up assembling respectively with the axial displacement restriction of two bearings at two ends, 5 formation rotating shafts 4; Reinforced seal 9 has formed sealing completely with rotating shaft 4 like this, and rotating shaft 4 can rotate flexibly.Flange 3 is provided with installing hole, and sealing ring 10 is housed on it, realizes the installation sealing of the utility model.Rotating shaft 4 one ends are provided with input interface 1 and output interface 7, and input interface 1 can be connected with the output interface 12 of operating mechanism, and output interface 7 can be connected with the input interface 11 of link gear.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the utility model.
