Abstract
The utility model discloses a cylinder sealing packing device for compressor, comprising a packing box, and a choked flow ring, a sealing ring, and a regulating ring successively mounted in the packing box. The choked flow ring and the sealing ring are the rings composed of three same ring sections whose openings are mutually applied. The outer ring wall of each ring section is provided with a groove in which a spring is mounted. The opening of each ring section of the choked flow ring is positioned in the radial direction of the ring. The included angle between the sectional planes of the contiguous openings of each ring section of the sealing ring is 60 degrees. The utility model has good sealing effect, and eliminate the phenomenon of gas leakage of the original equipment, meeting the requirement of normal operation of the equipment.
Description
Technical field
The utility model relates to a kind of improvement of stuffing box packing device.
Background technique
The seal ring of the stuffing box packing device of the compresser cylinder of Xiao Shouing is that ring-type is only opened one straight mouthful in the market, is equipped with 2 in each stuffing box, and the copper block ring is a not opening of ring-type.There are a lot of problems in this structure, the one, the seal ring opened gap is excessive, spring can not be fixed, and can not hold tightly on piston rod, the copper block ring is opening not, and and the gap between the piston rod bigger, can not play good seal action.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good seal performance is provided, and can satisfy the compressor seal filler device that manufacturing mechanism runs well
The purpose of this utility model realizes by following proposal.
The utility model compresser cylinder stuffing box packing device, it comprises stuffing box, is contained in block ring, seal ring and regulating ring in the stuffing box successively, described block ring and seal ring are respectively by three identical annulus that the ring section is formed of fitting mutually between opening, on the external annulus of each ring section, have groove, in described groove, spring is housed; The opening of each ring section of described block ring is positioned at annulus radially, and the angle between each ring section adjacent apertures section of described seal ring is 60 °.
The utility model is because the block ring that adopts is three lobe one, adding spring on the external annulus fixes, seal ring is 60 ° of three lobe angles, opening does not stay the gap, adds spring on the external annulus and fixes, and regulating ring is an annular ring, three kinds of endless loops have been formed the sealing configuration of one, thereby sealing effect is good, has overcome the gas leak phenomenon that original equipment exists, and has satisfied the needs that equipment runs well.
