Abstract

The invention discloses an abrasion-resisting piston sealing ring for a natural gas compression cylinder. The sealing ring comprises two symmetrically-arranged check rings and a sealing ring body located between the two check rings. The sections of the check rings are in a vertically-placed arch bridge shape, and the section of the sealing ring body comprises a middle O-shaped segment, an upper rectangular segment and a lower rectangular segment and is right matched with that of the check rings. A middle steel wire framework is arranged in the middle O-shaped segment, an upper steel wire framework is arranged in the upper rectangular segment, a lower steel wire framework is arranged in the lower rectangular segment, the section of the middle steel wire framework is in an O shape, the section of the upper steel wire framework is rectangular, and the section of the lower steel wire framework is rectangular. Through the above manner, the sealing ring is simple and reasonable in structure, good in sealing performance, capable of bearing large pressure, and long in service life.

Description

The wear-resistant piston packing of natural gas compressing cylinder
Technical field
The present invention relates to natural gas compressing technical field, particularly relate to a kind of wear-resistant piston packing of natural gas compressing cylinder.
Background technology
Natural gas is one of safer combustion gas, and it does not contains carbon monoxide, lta yet, once leaks, can diffuse up immediately, is difficult to accumulation and forms damp, and safety is higher.
Natural gas compressing cylinder noise is little, efficiency is high, the most progressively replaces conventional compression equipment.Natural gas compressing cylinder to be applied to many sealing rings, and existing sealing ring tightness can not be good, and service life is short.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of wear-resistant piston packing of natural gas compressing cylinder, and simple and reasonable, good seal performance, it is possible to bear bigger pressure, service life is long.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of wear-resistant piston packing of natural gas compressing cylinder, including: two symmetrically arranged back-up rings and the sealing ring body between two back-up rings, the cross section of described back-up ring is in the arch bridge type vertically placed, the cross section of described sealing ring body includes middle O type section, upper rectangle section and lower rectangle section, just matches with back-up ring;
Described middle O type intrasegmental part is provided with process wire skeleton, described upper rectangle intrasegmental part is provided with steel-wire carcass, described lower rectangle intrasegmental part is provided with lower steel-wire carcass, the cross section of described process wire skeleton is O type, the cross section of described upper steel-wire carcass is rectangle, and the cross section of described lower steel-wire carcass is rectangle.
In a preferred embodiment of the present invention, described process wire skeleton uses rustless steel steel wire.
In a preferred embodiment of the present invention, described upper steel-wire carcass uses rustless steel steel wire.
In a preferred embodiment of the present invention, described lower steel-wire carcass uses rustless steel steel wire.
The invention has the beneficial effects as follows: the wear-resistant piston packing of natural gas compressing cylinder of the present invention, simple and reasonable, good seal performance, it is possible to bear bigger pressure, service life is long.
Accompanying drawing explanation
