Gas relay

The utility model relates to the technical field of gas relays, and discloses a gas relay which comprises a connecting column, the top end of the connecting column is fixedly provided with a top cover, one side of the connecting column is provided with an opening cup, an adjusting rod and a dry reed node, the adjusting rod is located below the opening cup, the dry reed node is located below the adjusting rod, and the top cover is fixedly arranged on the top end of the connecting column. According to the utility model, the oil-immersed pressure sensor is arranged on the gas relay baffle plate, and the change of the impact force borne by the baffle plate is converted into the change of the rotation angle according to the positive correlation between the rotation angle of the baffle plate and the impact force borne by the baffle plate, so that the extraction of the rotation angle signal of the baffle plate is realized. The problems that when a traditional novel gas relay is used, due to the fact that certain ear
