Zusammenfassung: | The utility model relates to a meter correction valve used for an SF6 gas assembling device. The meter correction valve comprises a valve body and a valve ball, a four-way type channel is formed inside the valve body, the valve ball is located in the intersection center of the four channels, every two of the first channel, the second channel and the third channel in the four channels are perpendicularly arranged, the second channel and the fourth channel are arranged along the same axis, the outer end of the first channel and the outer end of the second channel are connected with self-sealing gas charging connectors through sealing rings, the self-sealing gas charging connector of the first channel is provided with a connecting block used for installing a gas density relay, the self-sealing gas charging connector of the second channel is provided with a meter connector, a valve ball handle is arranged at the outer end of the third channel, and a connector communicated with an air chamber of a high voltage switch device is arranged in the fourth channel. The self-sealing gas charging connectors of the meter correction valve can guarantee that SF6 gas cannot be leaked to the exteriors of the channels; when external instruments are disassembled or the gas density relay is corrected, the SF6 gas in the high voltage switch device cannot be leaked. |
