Abstract
The utility model discloses a compressor stuffing that is used for an air-entraining station, which has the advantage of high-pressure sealing. The compressor stuffing comprises a stuffing sealing body that is composed of at least one stuffing box; a sealing ring that adapts to a sealing-ring surface of the sealing body is arranged inside the stuffing box; a throttle ring that adapts to the sealing-ring surface of the sealing body is arranged inside the stuffing box, which is close to one end of an air cylinder cavity, of the stuffing sealing body. For a throttle ring that adapts to the sealing-ring surface of the sealing body is arranged inside the stuffing box, which is close to one end of an air cylinder cavity, of the stuffing sealing body, the high pressure air inside the air cylinder can be changed to be a middle-pressure and low-pressure air in throttling and pressure reduction way when the high-pressure air passes through the throttle ring, so that when the air passes through the following sealing rings, the impact of the air on the sealing ring can be reduced, thereby improving the sealing effect of the sealing ring; the compressor stuffing is particularly applicable to be popularized for application on the high-pressure sealing.
Description
Technical field
The utility model relates to a kind of filler, especially relates to a kind of compressor packing that uses in gas station.
Background technique
At present, in double-acting cylinder, filler is the parts that are used for sealing cylinder seat and piston rod gap, and filler is arranged in the cylinder block, the principle of its sealing is to utilize the inner edge of filler and piston rod to match, and utilizes the combination of choked flow and two kinds of effects of throttling to seal.General three, the six flap seal rings that adopt of filler of the prior art are made Sealing, wherein the general structure that adopts oblique three lobes of the seal ring of three valve structures.The problem that adopts the sealing form to exist is: 1, its complex structure of the seal ring of six valve structures, and working life is low, easily produces and leaks, and its structure is as depicted in figs. 1 and 2; 2, owing to only adopt three, six flap seal rings to seal in the filler, cause the sealing effect when seals high pressure gas poor, so only can be used on the low pressure seal.
The model utility content
Technical problem to be solved in the utility model provides a kind of compressor packing that can be used for high pressure sealing.
The technological scheme that its technical problem that solves the utility model adopts is: compressor packing, comprise the packing seal body that constitutes by at least one stuffing box, in stuffing box, be provided with and the suitable seal ring of the sealing anchor ring of seal, be provided with and the suitable restrictor ring of the sealing anchor ring of seal near in the stuffing box of cylinder cavity one end at the packing seal body.
As the preferred version of technique scheme, described restrictor ring is twice, divides to be located in two stuffing boxes.
Further be that the twice restrictor ring is respectively and soaks copper graphite restrictor ring and this special envelope restrictor ring.
Further be between adjacent two stuffing boxes, to be provided with the O RunddichtringO.
Further be in stuffing box, to be provided with the block ring of being close to seal ring.
Further be that described seal ring is oblique three flap seal rings.
The beneficial effects of the utility model are: by the sealing anchor ring suitable restrictor ring of setting in the close stuffing box of cylinder cavity one end of packing seal body with seal.Can make pressurized gas in the cylinder by restrictor ring the time, become by the throttling step-down in, low-pressure gas, thereby when gas passes through follow-up seal ring, can reduce impact, improve the sealing effect of seal ring, be particluarly suitable for promoting the use of above the high pressure sealing seal ring.

Fig. 2 is the A-A direction sectional view of Fig. 1;
Fig. 3 is a structure diagram of the present utility model.
Fig. 4 is the structure diagram of oblique three flap seal rings.
Be labeled as among the figure: stuffing box 1, seal ring 2, packing seal body 3, soak copper graphite restrictor ring 4, this special envelope restrictor ring 5, O RunddichtringO 6, block ring 7, sealing anchor ring 8.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 2, compressor packing of the present utility model, comprise the packing seal body 3 that constitutes by at least one stuffing box 1, in stuffing box 1, be provided with and the suitable seal ring 2 of the sealing anchor ring 8 of seal 3, at packing seal body 3 near being provided with in the stuffing boxes 1 of cylinder cavity one end and the suitable restrictor ring of the sealing anchor ring 8 of seal 3.By near being provided with in the stuffing box 1 of cylinder cavity one end and the suitable restrictor ring of sealing anchor ring 8 of seal 3, make pressurized gas in the cylinder at restrictor ring place expenditure and pressure, in becoming after making pressurized gas by restrictor ring, low-pressure gas, thereby can avoid the impact of pressurized gas to follow-up seal ring 2, improve the sealing effect of seal ring 2, thereby be adapted at using above the high pressure sealing.
For reaching above-mentioned expenditure and pressure effect better, described restrictor ring is twice, divides to be located in two stuffing boxes 1.Like this, pressurized gas by behind the first road restrictor ring expenditure and pressure again through the second road restrictor ring expenditure and pressure, in can better pressurized gas being reduced to, low-pressure gas, improve the sealing effect of seal ring 2.Restrictor ring can be chosen material such as teflon, phenolic plastic, pottery, and as preferred embodiment, the twice restrictor ring is respectively and soaks copper graphite restrictor ring 4 and this special envelope restrictor ring 5.Soak copper graphite restrictor ring 4 and can improve heat resistance well, generally can reach 400～500 ℃, can on high pressure sealing, use well, this special envelope restrictor ring 5 then has less starting and kinetic friction force, even under low speed, also can guarantee easy motion, no creeping phenomenon, and premium properties such as wear-resistant, anti-extrusion, high temperature resistant are arranged.
For preventing that gas from leaking from producing between adjacent two stuffing boxes 1, is provided with O RunddichtringO 6 between adjacent two stuffing boxes 1.
For reaching sealing effect better, in stuffing box 1, be provided with the block ring 7 of being close to seal ring 2.Like this, through in after the restrictor ring throttling, low-pressure gas is more conducive to the sealing of follow-up seal ring 2 after through block ring 7 choked flows, through after the choked flow repeatedly, can make sealing effect reach best.
For adapting to the to-and-fro motion of compressor piston rod, in the above embodiment, described seal ring 2 is oblique three flap seal rings.In packing seal, the seal ring of oblique three lobes has good reciprocating dynamic seal characteristic, and structure as shown in Figure 4.
