SF6 is multifunctional joint for measurement

The utility model discloses a SF6 is multifunctional joint for measurement, it can be dismantled and be connected messenger as an organic whole SF6 passageway intercommunication between them, the other end and SF6 holding vessel intercommunication including the connector and the adapter that all are equipped with the SF6 passageway, the one end and the adapter of connector, carry on little water when measuring with the adapter and the water appearance that declines be connected can, it can to pull down when carrying out the check -up of density relay that the adapter is connected the connector with corresponding equipment. Only needing when little water is measured to carry on with adapter and little water appearance be connected can, only need pull down when carrying out the check -up of density relay the adapter with connector and corresponding equipment be connected can, need not to pull down whole joint, has improved work efficiency, thereby has avoided the measuring stick in -process to exit repeatedly a
