Description

Technical Field

[0001] The utility model relates to the technical field of gas separation pipelines, in particular to a gas separation pipeline convenient for installation. Background Technique

[0002] A gas separation pipeline is a specially designed pipeline system for gas transportation during the gas separation process. This pipeline system can effectively cope with the unstable pressure generated during gas transportation, thus better cooperating with gas separation equipment to ensure the smooth progress of the gas separation process.

[0003] After retrieval, a gas separation pipeline with high pressure resistance and convenient installation, with the publication number CN217683775U, includes a first pipe body. A second pipe body is arranged on the opposite side of the first pipe body. First connection plates and second connection plates are arranged at the front and rear ends of the first pipe body and the second pipe body; the first connection plate is located on the opposite side of the second connection plate. Bolts are annularly distributed inside the first connection plate and the second connection plate. A positioning block is arranged on the outer surface of one end of the second connection plate. For this gas separation pipeline with high pressure resistance and convenient installation, the limiting groove arranged between the spacer ring and the reinforcing ring can fix the position of the airbag. When the pipeline air pressure is greater than the normal value, the airbag can be squeezed. Through the deformation of the airbag, it can fit more tightly at the pipeline connection to achieve the purpose of buffering, improve the high pressure resistance performance of the pipeline, and further enhance the sealing performance of the pipeline connection.

[0004] Based on the above patent, through the limiting groove arranged between the spacer ring and the reinforcing ring, the position of the airbag can be fixed. When the pipeline air pressure is greater than the normal value, the airbag can be squeezed. Through the deformation of the airbag, it can fit more tightly at the pipeline connection to achieve the purpose of buffering, improve the high pressure resistance performance of the pipeline, and further enhance the sealing performance of the pipeline connection. By arranging a sealing gasket inside the sealing groove, when the first pipe body and the second pipe body are connected, the positioning block slides inside the sealing groove and squeezes the sealing gasket. Cooperating with the limiting groove inside the limiting groove, it can provide double sealing protection for the pipeline, avoid gas leakage affected by high pressure, and thus increase the safety of gas separation. However, during the assembly of the separation pipe in the use of this patent, the installation efficiency is low. Low-efficiency installation usually requires more time and labor, resulting in an increase in labor costs and construction expenses. And when the installation process takes a long time, it will delay the startup of the entire system, affecting production plans and operation efficiency. Content of the Utility Model
