The requirement of condition often leads to slewing leakage, and equipment leakage not only influences the normal work of equipment, and also results in ring
The serious pollution in border, high-temperature medium, poisonous and harmful medium, which once leak, can jeopardize life safety.
Utility model content
The technical problems to be solved in the utility model is in order to overcome the defects of the prior art, now to provide a kind of for revolving
Turn the double-sealing device of equipment, the dual structure of packing seal and mechanical seal, sealing effect is good, and physical life is long, reliably
Property is good, avoids device drainage, avoids pollution of the leakage to natural environment.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of double-sealing device for slewing of the utility model, it is characterized in that, it is described to be used for slewing
Double-sealing device include drive shaft, locking nut, gland, stuffing box, filler, mounting base, upper seal support, upper stationary ring
Group, rotating ring group, lower stationary ring group, bottom sealing socket and O-ring seal, the stuffing box is set to the upper surface of described mounting base, described
Drive shaft is arranged in the center of the stuffing box and mounting base, and the filler is set in the stuffing box, the gland
Be set to the top of the stuffing box, the stuffing box is connected with the gland by the locking nut, it is described on
Seal receptacle and bottom sealing socket are set to below the mounting base, and the upper seal support and the bottom sealing socket are connected by bolt
It connects, the upper stationary ring group and lower stationary ring group are set to the inside of the upper seal support and bottom sealing socket, and the rotating ring group is set to
The centre of the upper stationary ring group and lower stationary ring group, the lower end of the drive shaft are connected with the rotating ring group.
Preferably, the upper seal support is provided with first circulation mouth.
Preferably, the bottom sealing socket is provided with second circulation mouth.
Preferably, the rotating ring group is internally provided with spring.
Preferably, the gland and stuffing box are set as the conical surface.
The positive effect of the utility model is:
The utility model uses the dual structure of packing seal and mechanical seal, and sealing effect is good, and physical life is long, reliably
Property is good, avoids device drainage, avoids pollution of the leakage to natural environment.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the preferred embodiment of the utility model.
Fig. 2 is the sealing gland structural schematic diagram of the preferred embodiment of the utility model.
Fig. 3 is the stuffing box structural schematic diagram of the preferred embodiment of the utility model.
Specific embodiment
The utility model is further illustrated below by the mode of embodiment, but is not therefore limited in the utility model
Among the embodiment described range.
Referring to Figure 1, Fig. 2 and Fig. 3, a kind of double-sealing device for slewing of the utility model, including driving
Axis 1, locking nut 2, gland 3, stuffing box 4, filler 5, mounting base 6, upper seal support 7, upper stationary ring group 8, rotating ring group 9, under
Stationary ring group 10, bottom sealing socket 11 and O-ring seal 12, stuffing box 4 are mounted on the upper surface of mounting base 6, and drive shaft 1 passes through stuffing box
4 and mounting base 6 center, filler 5 is placed on the inside of stuffing box 4, and gland 3 covers the top in stuffing box 4, stuffing box 4
