Description
Technical Field
The utility model particularly relates to a packing component of a natural gas booster compressor, and belongs to the technical field of compressor components.
Background
The compressor for natural gas supercharging operation can adopt a compressor with a V-shaped structure, and the compressor is a two-stage compression, double-acting, cylinder water-cooling, oil-free and piston type compressor; the arrangement of the cylinders is V-shaped, and the first-stage cylinder and the second-stage cylinder are arranged in a row respectively; in the installation parts, the connecting rod part, the crosshead part and the crosshead slide way part are respectively provided with two sets of the same parts; when the compressor runs, the rotary motion is changed into the reciprocating motion of the piston in the cylinder through the crankshaft, the connecting rod and the crosshead, when the piston moves, in order to avoid the gas in the cylinder from leaking from the piston rod, sealing packing needs to be arranged at the piston rod and the cylinder, and when the existing sealing packing is used, the trace natural gas leaking from the sealing ring easily causes interference to the surrounding environment.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a natural gas booster compressor packing assembly which can lead a small amount of natural gas leaked from a sealing ring to an outdoor safe place to be discharged, and is simple and safe to use.
The packing component of the natural gas booster compressor comprises a packing cylinder, wherein a sealing component is arranged on the inner side of the packing cylinder; a packing flange is pressed at the end part of the packing cylinder; the sealing assembly comprises a plurality of stuffing boxes with the same type, and the stuffing boxes are oppositely provided with piston through holes for the piston rods to pass through; a main sealing ring is arranged on the inner side of each stuffing box; a pressure reducing ring is arranged between the main sealing ring and the stuffing box; the stuffing adopts the combined action of a plurality of stuffing boxes, so that multi-section sealing is formed in the stuffing cylinder, each section is in an independent sealing state for the motion of the piston rod, the whole stuffing sealing effect is good, and the high sealing period is greatly prolonged; an exhaust channel is formed in the packing flange and the packing box close to the packing flange; the inner side of the exhaust channel is communicated with the piston through hole; a sewage draining outlet is arranged outside the exhaust channel; the sewage draining outlet is connected to an outdoor draining point through a hose; the packing component is provided with an air chamber and a front sealing ring, and a small amount of natural gas leaked from the sealing ring is discharged to a sewage discharge outlet through the air chamber, and is guided to an outdoor safe place to be discharged by a hose with the inner diameter of phi 8 when in use.
Further, the primary sealing ring is of a single-layer or multi-layer structure; the number of the pressure reducing rings is matched with the number of layers of the main sealing rings.
Further, the packing flange and the packing box close to the packing flange are assembled to form the air chamber and the front sealing ring.
Compared with the prior art, the natural gas booster compressor packing component can lead a trace amount of natural gas leaked from the sealing ring to an outdoor safe place to be discharged, is simple and safe to use, and has high sealing strength of the piston position.
