Gas pipeline self-closing valve with remote transmission function

The invention relates to the technical field of self-closing valves, and provides a gas pipeline self-closing valve with a remote transmission function, comprising a valve body used for communicating with a pipeline; the self-closing mechanism is arranged in the valve body, and the self-closing mechanism is used for opening or closing a pipeline passage; the first end of the first pull rod is in transmission connection with the self-closing mechanism through a leather film, the second end of the first pull rod is a free end, the first pull rod moves in the direction perpendicular to the pipeline along with the change of the gas conveying pressure of the pipeline, and the first pull rod comprises an insulation area and a conductive area; and the detection device is in contact connection with the first pull rod. According to the technical scheme, the technical problem that in the prior art, whether the self-closing valve is in the opening state or the closing state cannot be remotely known is solved. 本发明涉及自闭阀技术
