Technical Field
The utility model relates to a bury ground gas pipeline with safe auxiliary assembly specifically indicates a bury ground gas pipeline with high-efficient plugging device.
Background
The buried gas pipeline is used for gas transportation, and is the only way for transporting a large amount of natural gas on land. With the extension of the service life of the buried gas pipeline, the buried gas pipeline is likely to generate small-point leakage due to the aging of the buried gas pipeline and the influence of external factors. At present, two leakage stopping devices and two leakage stopping modes are summarized aiming at the buried gas pipe, one is to perform leakage stopping on a leakage point of a gas pipeline through a soft sealing pressing block matched with the size of the leakage point, and the other one is to push the soft sealing pressing block to press the leakage point through a driving mechanism such as a compression screw and the like until the leakage point is completely stopped up by the soft sealing pressing block. And the other method is that the leakage stopping rubber layer is driven to forcibly seal the leakage point by an adjustable locking mode or other pressure gradual pressing mechanisms, so that the leakage stopping is formed. However, the two buried gas pipe leakage stopping modes/devices have a big disadvantage that whether the leakage stopping is completely in place is difficult to judge, the judgment can be carried out only by an external air pressure detection system, and the judgment efficiency and the judgment precision are uncertain. And once the leaking stoppage fails, no second leakage-proof measure exists, so that great hidden danger exists. Consequently, whether the judgement that designs a section can be effectively accurate fast is the leaking stoppage target in place, and can also effectively carry out the leak protection after the leaking stoppage became invalid, and can in time send the high-efficient plugging device for burying ground gas pipeline of leaking stoppage inefficacy signal is the utility model discloses a research purpose.
