Abstract

The invention discloses a novel natural gas compression cylinder. The novel natural gas compression cylinder comprises an upper cylinder barrel, a lower cylinder barrel, a piston rod and a guide sleeve. The piston rod penetrates the guide sleeve. The two ends of the piston rod are correspondingly provided with an upper piston and a lower piston. An O-shaped sealing ring and a combined sealing ring are arranged between the upper piston and the upper cylinder barrel. An O-shaped sealing ring and a combined sealing ring are arranged between the lower piston and the lower cylinder barrel. Each combined sealing ring comprises two check rings and a sealing ring body. The section of each check ring is in the shape of a vertically-arranged arch bridge. The section of each sealing ring body comprises a middle O-shaped segment, an upper rectangular segment and a lower rectangular segment. A middle steel wire framework is arranged in each middle O-shaped segment. An upper steel wire framework is arranged in each upper rectangular segment. A lower steel wire framework is arranged in each lower rectangular segment. The section of each middle steel wire framework is in an O shape. By means of the manner, the novel natural gas compression cylinder is good in sealing performance, the two sealing rings are combined, the bearing pressure is large, and it is guaranteed that natural gas compression is conducted smoothly.

Description

technical field [0001] The invention relates to the technical field of natural gas compression, in particular to a novel natural gas compression cylinder. Background technique [0002] Natural gas is one of the safer gases. It does not contain carbon monoxide and is lighter than air. Once leaked, it will spread upward immediately, and it is not easy to accumulate to form explosive gas, which is relatively safe. [0003] The natural gas compression cylinder has low noise and high efficiency, and is currently gradually replacing traditional compression equipment. There is a piston on the natural gas compression cylinder, and a sealing ring is used between the piston and the cylinder wall. The existing sealing ring has poor sealing performance and needs to be improved. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a new type of natural gas compression cylinder, which has a simple and reasonable structure, good s...
