Description
Technical field
This utility model is related to a kind of gas compressor, particularly a kind of sealing device for gas compressor.
Background technology
At present, mainly include being made up of at least three stuffing boxes in the existing sealing device for gas compressor,
Black box is provided with stuffing box, although can carry out a certain degree of sealing, but, due to the restriction of structure, it is impossible to carry
The pretension of each element end face of high filler is than pressure so that sealing property is poor, and gas is easier to reveal.
Utility model content
The purpose of this utility model is just to provide a kind of sealing property that enables to preferably is used for the close of gas compressor
Seal apparatus.
The purpose of this utility model realizes that by such technical scheme a kind of sealing for gas compressor is filled
Put, including stuffing box A and stuffing box B, at least one stuffing box C is provided between described filler box A and stuffing box B, described
Stuffing box A, stuffing box B and stuffing box C are connected by the pull bar through center, in described filler box C arrange black box,
Pressure-reducing ring is provided with described filler box B, between the black box and stuffing box C, is provided with elastic component.
Wherein, the black box includes interior sealing ring, choke ring and the pressure pad being successively set in stuffing box C, described
Elastic component is located between the pressure pad and stuffing box C inwalls.
Wherein, the elastic component is axial thrust spring, and one end of the axial thrust spring withstood on pressure pad, the other end
Withstand on the inwall of stuffing box C.
Further, stuffing box D is provided between described filler box C and stuffing box B, is set in described filler box D successively
Sealing ring, choke ring and pressure pad is equipped with, between the pressure pad and stuffing box D inwalls, is provided with axial thrust spring.
As a result of above-mentioned technical proposal, this utility model has simple structure, with low cost, service-strong excellent
Point, improves the pretension of each element end face of filler than pressure using it, shortens self-tightening sealing process so that sealing property is more preferable,
Safer, substantially increase the bulk life time of filler.
Description of the drawings
Description of the drawings of the present utility model is as follows：
Fig. 1 is the first structural representation of the present utility model；
Fig. 2 is second structural representation of the present utility model；
Fig. 3 is this third structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in further detail, but this utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within this utility model
Claim scope required for protection.
Embodiment 1：As shown in figure 1, a kind of sealing device for gas compressor, including stuffing box A1 and stuffing box
B2, is provided with least one stuffing box C3 between described filler box A1 and stuffing box B2, described filler box A1, stuffing box B2 and
Stuffing box C3 is connected by the pull bar 4 through center, arranges black box, in described filler box B2 in described filler box C3
Pressure-reducing ring 5 is provided with, between the black box and stuffing box C3, is provided with elastic component.
Wherein, the black box includes interior sealing ring 6, choke ring 7 and the pressure pad 8 being successively set in stuffing box C3,
The elastic component is located between the pressure pad 8 and stuffing box C3 inwalls.
Wherein, the elastic component is axial thrust spring 9, and one end of the axial thrust spring 9 withstands on pressure pad 8, separately
One end is withstood on the inwall of stuffing box C3.
In this utility model, due to axial thrust spring 9 so that the thrust of axial thrust spring 9 is to close
In seal ring 6, sealing ring 6 is just close on the end face of stuffing box A1, improves the pretension of filler end face than pressure so that sealing property
More preferably.
Further, as described in Figure 2, stuffing box D10 is provided between described filler box C3 and stuffing box B2, fill out described
Sealing ring 6, choke ring 7 and pressure pad 8 is disposed with magazine D10, is arranged between the pressure pad 8 and stuffing box D10 inwalls
There is axial thrust spring 9.This is done to actually used needs, it is, of course, also possible to as shown in figure 3, increase as needed
More stuffing boxes and black box and axial thrust spring 9.
