Abstract

The invention discloses a gas pipe network high-pressure magnetic repair device. The device comprises a magnetic portion, a lever portion and a diffusion drainage portion, wherein the magnetic portionis a driving force source of the whole repair device, the diffusion drainage portion can diffuse leaked natural gas to a safety area so as to avoid damage to repair persons due to large concentrationof natural gas, meanwhile, the pipeline plugging operation can be carried out, the action of the lever portion is to connect the magnetic portion and the diffusion drainage portion, so that the diffusion drainage portion is provided with strong magnet attraction force. The device has the beneficial effects that during gas leakage repair of a paramagnetic pipeline, the super-strong suction force of a magnet is used for resisting the impact force generated by the high-pressure air flow, so that leakage of a high-pressure pipe network is realized.

Description

technical field [0001] The invention belongs to the technical field of natural gas pipeline transportation, focuses on the technical field of emergency repair for pipeline leakage, and specifically relates to a high-pressure magnetic emergency repair device for a gas pipeline network. Background technique [0002] With the rapid growth of the laying length of my country's urban gas pipeline network, the requirements for the emergency repair technology of the urban gas pipeline network are also increasing year by year. The emergency repair technology is divided into two types, the stop static pressure plugging repair and the non-stop transmission under pressure plugging repair. Pipeline sealing under pressure is based on the sealing mechanism of sealing materials under dynamic conditions. As the proportion of gas in the air gradually increases and reaches the limit of explosion, an explosion will occur when an open flame or spark is encountered at this time, and the high-pres...
