Abstract

The invention relates to the technical field of gas conveying, and discloses a gas stopping operation device and method for a gas pipeline, and the device comprises a first vertical pipe, a second vertical pipe, a transverse pipe, a first ball valve, a second ball valve, a third ball valve, a fourth ball valve, a first pressure gauge, a second pressure gauge and a main valve arranged on the gas pipeline; the lower end of the first vertical pipe is communicated with the gas pipeline on one side of the main valve through a first ball valve, and the lower end of the second vertical pipe is communicated with the gas pipeline on the other side of the main valve through a fourth ball valve; one end of the transverse pipe is communicated with the first vertical pipe through a second ball valve, and the other end of the transverse pipe is communicated with the second vertical pipe through a third ball valve; the first pressure gauge is used for measuring air pressure in the first vertical pipe, and the second pressure gauge is used for measuring air pressure in the second vertical pipe. According to the gas stopping operation device and method for the gas pipeline, the phenomena of noise and pollution caused by directly discharging the gas into the atmosphere are avoided.

Description

technical field [0001] The invention relates to the technical field of gas transportation, in particular to a gas shut-off operation device and method for gas pipelines. Background technique [0002] During the outage operations of gas pipelines such as rush repair, maintenance, and connection of new pipes, huge noise is often generated due to the need to discharge the residual gas in the outage pipeline network. Currently, the noise when discharging gas is usually above 45 decibels, causing noise Phenomena such as disturbing residents and user complaints greatly affect the normal life of residents near the operating site; and direct gas emission will pollute the environment, which is also an economic waste. Contents of the invention [0003] The technical problem to be solved by the present invention is: when the gas pipeline discharges the residual gas in the gas shut-off pipe network during the gas shut-off operation, it will generate noise and pollute the environment, ...
