Description
Technical field
The utility model relates to compressor field, particularly relates to a kind of for Reciprocting piston compressor gland sealed pressure-reducing ring and filler assembly thereof.
Background technique
Filler assembly carries the important process preventing leakage of compressed gas, and under mainly relying on the effect of self-tightening power, packing ring holds piston rod tightly to form sealing.In filler assembly, arrange pressure-reducing ring, its effect is reduced pressure to pressurized gas in filler front end, to reduce the load of filler when sealing.Current pressure-reducing ring structure is simple, and suffered load is comparatively large, and effect of easing stress is undesirable, and appearance very easily lost efficacy.When compressor piston rod pushes the work forward, larger pressure reduction can be formed to pressure-reducing ring, substantially reduce the life-span of pressure-reducing ring.
Model utility content
The purpose of this utility model is just to provide one to solve the problems referred to above, for Reciprocting piston compressor gland sealed pressure-reducing ring and filler assembly thereof.
To achieve these goals, the technical solution adopted in the utility model is: a kind of for Reciprocting piston compressor gland sealed pressure-reducing ring, described pressure-reducing ring is that the sector unit of three deciles is spliced, and outer shroud circumferential surface offers annular spring groove, one of them end face of described pressure-reducing ring evenly offers vent slot and decompressing groove, described vent slot and decompressing groove are all through between the inner ring and outer shroud of pressure-reducing ring, and described decompressing groove is V-shaped groove;
As preferably, described vent slot is square groove;
As preferably, described decompressing groove is positioned at the stitching portion of sector unit;
As preferably, described vent slot is positioned at the middle part of sector unit;
A kind of Reciprocting piston compressor filler assembly, comprise the compressor packing throttling box of tubular, described compressor packing throttling box side is that piston is imported and exported, opposite side is pressurized gas import, pressure-reducing ring standing groove is provided with in described filler throttling box, pressure-reducing ring is positioned at standing groove, and one of them end face of described pressure-reducing ring evenly offers vent slot and decompressing groove, and the end face of described decompression endless belt vent slot and decompressing groove is towards the pressurized gas import side of housing;
As preferably, in described compressor packing throttling box, be provided with multiple pressure-reducing ring;
As preferably, described compressor packing throttling box is also provided with restrictor ring and multistage dense seal ring.
Compared with prior art, the utility model has the advantage of: the utility model structure is simple, in piston pushing course, pressurized gas are by the vent slot on pressure-reducing ring, be full of the external diameter of pressure-reducing ring, reduce the gas pressure difference be subject to of pressure-reducing ring, can auto-compensation after the structure of three lobes makes pressure-reducing ring wear and tear, improve service behaviour and the life-span of pressure-reducing ring.
