Gas overrun detection and control interlocking device for gasometer

The utility model discloses a gas overrun detection and control interlocking device for a gasometer. The gas overrun detection and control interlocking device comprises a wirerope, a pulley, a direction board with gas storage scales, a pointer, a heavy lump and a proximity sensor. The gas overrun detection and control interlocking device for the gasometer can be used for accurately determining the highest limit and the lowest limit of gas storage in the gasometer, the highest limit and the lowest limit can be used as a determination basis for mutually verifying with analog quantity parameters of a single gasometer lever meter in a gasometer monitoring system to together determine whether the gas storage in the gasometer overruns or not and control in an interlocking mode, the gasometer can be ensured to work with a safe capacity range, defects about economy and timeliness in the prior art that a plurality of monitoring system gasometer level meters are used for verifying and determining gas storage overrun or the pressure of gas storage in a gasometer is acquired for verifying and determining gas storage overrun can be overcome. The gas overrun detection and control interlocking device for the gasometer is simple in structure, reliable in usage, low in cost, convenient to maintain and durable.
