Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated; the present embodiment is premised on technical solutions of the utility model; give detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As described in Figure, the utility model is a kind of SF
6gas valve device, comprises valve body 1, self-closed joint 2, SF
6density monitor 3, sealing gasket 8 and attachment cap 9, valve body 1 upper surface is by attachment cap 9 and SF
6density monitor 3 is connected, and valve body 1 lower surface and a side are provided with a self-closed joint 2, two self-closed joints 2 and SF
6density monitor 3 is connected by pipeline in valve body 1, a spool is provided with in valve body 1, spool is provided with sealing gasket 8 relative to one end of the self-closed joint of valve body 1 side, sealing gasket 8 selects PTFE teflon, decay resistance is strong, and valve body another side is provided with control gear, and the utility model is connected with high-tension switch gear body and adopts self-enclosed structure, be in high-tension apparatus body from two self-closed joints 2 to connect, the SF when the utility model connects high-tension apparatus body
6gas is connected automatically, when the micro-water measured in high-tension switch gear and tonifying Qi, also adopts self-enclosed structure, makes the SF in high-tension switch gear
6gas, not to outward leakage, can avoid the security of operation of pollution to air and high-tension switch gear, described control gear comprises limit stoper 4, stainless steel metal bellows 5, valve rod 6 and handle 7, handle 7 is connected with spool by valve rod 6, and can valve core movement be driven and sealing gasket 8 is coordinated with the self-closed joint inner seal of valve body 1 side, the stainless steel metal bellows 5 that can make valve core reset is provided with between described spool and valve body, stainless steel metal bellows 5 adopts corrugated stainless steel tubing to carry out sealing structure, full laser technique welding, sealability improves greatly, the utility model equipment is arranged on high-tension switch gear, under normal working, handle 7 is positioned at the position of "ON", corrugated stainless steel tubing 5 is in non-confined state, self-closed joint 2, SF
6density monitor 3 and another self-closed joint 2, three connects, and from any one self-closed joint 2, can carry out the micro-water in side and tonifying Qi to high-tension switch gear.After having operated, this self-closed joint 2 closes automatically, effectively avoids high-tension switch gear SF
6leakage Gas.When handle 7 is positioned at the position of "Off", self-closed joint 2 and the high-voltage switch gear bulk gas of valve body 1 side are isolated, and make self-closed joint 2 and the SF of valve body 1 lower surface
6density monitor 3 is communicated with, and carries out SF in preparation
6during the verification of density monitor 3, first handle 7 is to the direction turn being denoted as "Off", handle 7 is with ovable valve stem 6 to rotate together, valve rod 6 screws out from the screw thread of spool, due to the position-limiting action of limit stoper 4, valve rod 6 just promotes spool and moves forward and compress corrugated stainless steel tubing 5 simultaneously, until Sealing contacts with the sealing surface on valve body and compresses, thus blocks the intrinsic SF of high-voltage switch gear completely
6gas channel, thus SF
6density monitor 3 is just kept apart with Switch main body, then just can directly by self-closed joint 2 couples of SF of valve body 1 lower surface
6density monitor 3 verifies.After verification, handle 7 is to the direction turn being denoted as "ON", contrary with front, the SF of high-voltage switch gear body
6gas channel is opened, SF
6density monitor 3 is in normal working again.
