Embodiment
Below in conjunction with embodiment, the utility model is described in further details:
The utility model relates to the interface valve that a kind of SF6 density monitor connects, belong to three break valves, as depicted in figs. 1 and 2, the utility model comprises the conventional shut-off valve assemblies such as valve body, spool 4, valve rod 2, handwheel 6, the utility model and conventional break valve difference spool 4 are arranged sealing ring (sealing ring is only arranged on the one side needing to seal), and spool 4 and valve rod 2 are one.Valve rod 2 is arranged in valve body, and handwheel 6 is arranged on valve rod 2 end.For the ease of installing and using and convenient verification, need not dismantle during verification, and SF6 gas passage can be cut off when ensureing verification, the utility model valve body is provided with density monitor interface 3, inflation/deflation and verification interface 5, SF6 gas piping interface 7 and mount pad 8, inflation/deflation and verification interface 5 center line and valve rod 2 center line point-blank, density monitor interface 3 center line and valve rod 2 central axis, SF6 gas piping interface 7 center line and valve rod 2 central axis, simultaneously also with density monitor interface 3 central axis, side relative with density monitor interface 3 on valve body arranges mount pad 8, the utility model arranges three working positions, according to the diverse location of valve rod 2 in valve body, three different working positions are respectively:
