Abstract
The utility model discloses a packing and sealing device for high pressure gas. The packing and sealing device for the high pressure gas comprises a sealing socket, a sealing sleeve, a packing and sealing ring, a sealing compression ring and a piston rod. The packing and sealing ring is composed of a flow choking ring, a radial ring and a tangential ring in an overlying mode in sequence, a restrictor ring or the packing and sealing ring composed of the flow chocking ring and the tangential ring in an overlying mode is arranged between the sealing compression ring and the piston rod which are located at the two ends of the packing and sealing device, two buffer grooves are arranged on the inner ring of the restrictor ring located on the end portion, the section of each buffer groove is semicircular, and three radial gas guide grooves penetrate through an outer ring and an inner ring of the radial ring are evenly distributed on one side face of the radial ring. The packing and sealing device for the high pressure gas has the advantages that due to the fact that the buffer grooves are additionally arranged on the restrictor ring, the pressure of the high pressure gas in a cylinder is reduced after the high pressure gas passes the buffer grooves, impact on the packing and sealing ring by the high pressure gas is reduced, the service life of the packing and sealing ring is prolonged, and frequency and times for examination and repair are reduced. In addition, due to the fact that the three gas guide grooves are additionally arranged on a pressed face of the back radial ring, sealing property is improved, and self-compression and compensation are achieved.
Description
Technical field
The utility model relates to the packing seal technical field that has radially or tangentially compress.
Background technique
Along with quick development of modern science and technology, reciprocal compressor is day by day towards the development of supermatic aspect, the contact between complexity and zero, the parts is tightr gradually to cause machinery, in case certain part breaks down, tend to cause the paralysis of whole equipment, and fault and long repair time are usually caused the generation of enormous economic loss and personnel casualty accidents frequently.
Because the particularity of this device, compressor is reciprocating type associating compressor, one end compression hydrogen, one end is recycle hydrogen, and operational condition is harsh, and new hydrogen end Hydrogen Vapor Pressure boosts to 12.5MPa from 3.0MPa, the hydrogen sulfide that contains high concentration in the recycle hydrogen, hydrogen is inflammable and explosive, and explosion limit is the wideest, and hydrogen sulfide very easily makes the people poison; And pressurized gas frequent impact packing seal ring, cause the packing seal ring lost of life, maintenance frequency height, the risk that exists hydrogen and hydrogen sulfide to reveal.
The model utility content
Technical problem to be solved in the utility model provides and a kind ofly can effectively reduce the reciprocating type associating compressor maintenance frequency, stops the pressurized gas stuffing seal of hydrogen and hydrogen sulfide disclosure risk.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of pressurized gas stuffing seal, comprise sealing seat, stuffing box gland, packing seal ring, seal joint and piston rod, described seal joint is located in the stuffing box gland, described piston rod passes the seal ring setting, the packing seal ring is set, described packing seal ring setting at least three groups between seal ring inboard and the piston; Described packing seal ring is formed by stacking by block ring, radial ring and tangential ring successively, the packing seal ring that restrictor ring is set between the seal joint at two ends and piston rod or is formed by stacking by block ring and tangential ring, on the described restrictor ring inner ring that is positioned at the end twice cross section being set is semicircular dashpot, is evenly equipped with the radially gas guide groove that three roads connect Internal and external cycle on described radial ring one side.
Described block ring adopts the phosphor bronze material.
Described piston rod outer surface is provided with ceramic coating.
The beneficial effect that adopts technique scheme to produce is: by increasing dashpot at restrictor ring, make the pressurized gas in the cylinder reduce pressure through behind the dashpot, reduced the impact of pressurized gas to the packing seal ring, increase the service life, reduce the maintenance frequency, increased by three road gas guide grooves by the one side at back radial ring pressurized, make gas that restrictor ring comes by gas guide groove to external diffusion, the gas of diffusion produces one and holds power tightly between the slit of seal ring and stuffing box, improving sealability realizes increasing the service life from compressing and compensating.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model discloses a kind of pressurized gas stuffing seal (referring to accompanying drawing 1), comprise sealing seat 1, stuffing box gland 2, packing seal ring 3, seal joint 4 and piston rod 5, described seal joint 4 is located in the stuffing box gland 2, described piston rod 5 passes the seal ring setting, packing seal ring 3 is set between seal ring inboard and the piston, and described packing seal ring 3 arranges at least three groups; Its key improvements is: described packing seal ring 3 is successively by block ring 6, radial ring 8 and tangential ring 7 are formed by stacking, by restrictor ring (referring to accompanying drawing 2), radial ring (referring to accompanying drawing 3) and tangential cooperating between ring and block ring and the compressor piston rod, sealing, stop gas from slot leakage between piston rod and the cylinder, restrictor ring 9 is set or by block ring 6 and the tangential ring 7 packing seal rings 3 that are formed by stacking between the seal joint 4 at two ends and piston rod 5, on described restrictor ring 9 inner rings that are positioned at the end twice cross section being set is semicircular dashpot 10, is evenly equipped with the radially gas guide groove 11 that three roads connect Internal and external cycle on described radial ring 8 one sides.
Described block ring 6 adopts the phosphor bronze material, gives full play to the corrosion resistance of phosphor bronze, and is wear-resistant, but self-aligning is insensitive to deflection, can be subjected to characteristics such as radial load, selflubricating Maintenance free simultaneously, prolongs the working life of seal arrangement.
Described piston rod 5 outer surfaces are provided with ceramic coating, reduce block ring to the wearing and tearing of piston rod, have prolonged the working life of filler.
The utility model is by increasing dashpot at restrictor ring, make the pressurized gas in the cylinder reduce pressure through behind the dashpot, reduced the impact of pressurized gas to the packing seal ring, increase the service life, reduce the maintenance frequency, increased by three road gas guide grooves by the one side at back radial ring pressurized, make gas that restrictor ring comes by gas guide groove to external diffusion, the gas of diffusion produces one and holds power tightly between the slit of seal ring and stuffing box, improving sealability realizes increasing the service life from compressing and compensating.
