Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, and more specifically, to a gas pipeline drainer and a safe dredging device for drain pipes. Background Technology

[0002] A gas drain is an auxiliary device that collects and drains condensate, water, and debris from gas pipelines to ensure unobstructed gas flow. When the gas pipeline is operating normally, the condensate, water, and debris are drained through the drain pipe.

[0003] Because gas contains impurities such as tar, naphthalene, and dust, long-term operation of gas pipelines can easily cause blockages in the drain pipes of the drainers. Gas condensate, water, and dirt cannot be discharged. Gas pipelines filled with water can block gas flow and prevent operation, directly affecting the production and operation of users. In severe cases, the increased weight of the gas pipeline due to water filling may cause it to collapse.

[0004] Traditional cleaning methods typically involve manual cleaning, high-pressure water jet washing, or pressurized drilling for unblocking. These methods pose high safety risks, including gas leaks, poisoning, fires, and explosions. Clearly, it is necessary to improve existing unblocking methods. Utility Model Content
