Abstract
The utility model discloses a high-pressure packing sealing device for a compressor. The high-pressure packing sealing device comprises a throttling ring, a main sealing ring, a flow choking ring and two nitrogen sealing rings which are arranged in turn from inner to outer, wherein a spring is arranged on an annular edge of the flow choking ring; the flow choking ring is connected with the main sealing ring through a cylindrical pin which is arranged outside the flow choking ring; nitrogen sealing ring springs are arranged on annular edges of the nitrogen sealing rings; sealing ring slots are arranged inside annular parts of the nitrogen sealing rings; and the two nitrogen sealing rings are connected through a nitrogen sealing ring cylindrical pin. The high-pressure packing sealing device for the compressor has the beneficial effects that: the sealing effect of the sealing rings adopted by the high-pressure packing sealing device is excellent; the mounting is simple; the maintenance is convenient; the processing process is reduced; the manufacturing cost is lowered; the temperature of a piston rod is reduced; the service life of the piston rod is prolonged; the strength of the flow choking ring is increased; and the cold flow is avoided, so that the piston rod is prevented from being damaged by pulling.
Description
Technical field
The utility model relates to a kind of compressor high pressure stuffing seal.
Background technique
At present, the filler of compressor is the Sealing that wraps on the piston rod, and filler is made up of many groups ring, is included in the stuffing box, and functions such as lubricated, cleaning, cooling, sealing, temperature and pressure are provided during operation.Its effect is to stop the interior gas of cylinder between piston rod and Sealing, to leak.Cardinal principle is that gas gets in the annular groove of stuffing box from axial clearance and radial clearance, by gas pressure packing ring is fitted tightly respectively with piston rod surface and annular groove end face and realizes sealing.
Mostly the structure of the high pressure filler conventional design of using at present is a block ring, a tangential ring and a radial ring.Because the restriction of the annular groove degree of depth, the thinner thickness of tangential ring and radial ring, the high pressure air muscle power that it bears is easy to make its distortion and produces more frictional heat with piston rod rigid contact of pulsing; The temperature of piston rod is raise, thereby reduced working life, the sealability of filler also weakens simultaneously; Simultaneously, the lubricant oil because Reciprocting piston compressor will be annotated in filler when operation, tangential ring, radial ring often find that when opening and inspecting greasy dirt is more; Tangential ring, radial ring are clung, after tangential ring, the radial ring combination, axially do not have the gap basically; Cause seal ring to float, leaking appears in packing seal, produces and loses efficacy.
When surveying the rod seal of single Reciprocting piston compressor specific to axle, because it belongs to the single-acting type, pressure reduction is very little again simultaneously, adopts traditional packing seal mode to be difficult to realize the sealing to piston rod.Therefore, in the use of this type of device, exist because the piston rod packing sealing problem causes problems such as the piston rod temperature is too high, packing seal leakage always.
The model utility content
The purpose of the utility model provides a kind of compressor high pressure stuffing seal, to solve above technical barrier.
The described a kind of compressor high pressure stuffing seal of the utility model; Comprise restrictor ring, main seal ring, block ring and two nitrogen-sealed rings of setting gradually from the inside to the outside; Said block ring ring edge is provided with spring, and block ring is connected through the straight pin that is located at the block ring outside with main seal ring; Said nitrogen-sealed ring ring edge is provided with nitrogen-sealed ring spring, and annular inboard is provided with the seal ring otch, and two nitrogen-sealed rings are connected through nitrogen-sealed ring straight pin.
Utilize the encapsulating method of above-mentioned compressor high pressure stuffing seal, it may further comprise the steps:
1) the cleaning restrictor ring is surperficial, and restrictor ring is mounted to the high cylinder pressure side;
2) cleaning block ring and main seal ring surface meets main seal ring to installation on the pressure side, and in the main seal ring outside block ring is installed, and main seal ring is connected with block ring through straight pin, and axial clearance is matched with compressor arrangement;
3) cleaning nitrogen-sealed ring surface will be installed on the block ring outside through two nitrogen-sealed rings that nitrogen-sealed ring straight pin connects, and make the seal ring otch on two nitrogen-sealed rings be 90 ° of angular misalignments.
The beneficial effect of the utility model is: the employed seal ring seal effect of the utility model is splendid, installs simply, and is easy to maintenance, and manufacturing procedure reduces the manufacture cost reduction; The temperature of piston rod reduces, and has prolonged the working life of piston rod, and since the increase of block ring intensity avoided cold flow, thereby made piston rod phenomenon can not occur pulling.

Embodiment
Shown in Fig. 1-2; A kind of compressor high pressure stuffing seal shown in the utility model embodiment; It is characterized in that: comprise restrictor ring, main seal ring 4, block ring 1 and two nitrogen-sealed rings 6 of setting gradually from the inside to the outside; Said block ring 1 ring edge is provided with spring 2, and block ring 1 is connected through the straight pin 3 that is located at block ring 1 outside with main seal ring 4; Said nitrogen-sealed ring 6 ring edges are provided with nitrogen-sealed ring spring 7, and annular inboard is provided with 9, two nitrogen-sealed rings 6 of seal ring otch and is connected through nitrogen-sealed ring straight pin 8.
Utilize the encapsulating method of the compressor high pressure stuffing seal shown in the utility model embodiment, it may further comprise the steps:
1) the cleaning restrictor ring is surperficial, and restrictor ring is mounted to the high cylinder pressure side;
2) cleaning block ring 1 and main seal ring 4 surfaces meet main seal ring 4 to installation on the pressure side, and in main seal ring 4 outsides block ring 1 are installed, and main seal ring 4 is connected with block ring 1 through straight pin 3, and axial clearance is matched with compressor arrangement;
3) cleaning nitrogen-sealed ring 6 surfaces will be installed on block ring 1 outside through two nitrogen-sealed rings 6 that nitrogen-sealed ring straight pin 8 connects, and make two seal ring otch 9 on the nitrogen-sealed ring 6 be 90 ° of angular misalignments.
The utility model is used through novel structural type and material different after using through reality, greatly reduces fittings cost.Simultaneously owing to having guaranteed to have significantly reduced maintenance frequency by long-term operation, for enterprise has saved a large amount of maintenance expensess.
