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, a kind of high sealing SF6 gas valve device, a sealed plunger 4 is provided with in the valve pocket 11 of valve body 1, and sealed plunger 4 is sealed in valve pocket 11 by O RunddichtringO I 5, the surface of described sealed plunger 4 is provided with ring groove, O RunddichtringO I 5 is positioned at this ring groove to realize once sealing, and O RunddichtringO I 5 adopts Ethylene Propylene Terpolymer material, substantially increases valve body 1 sealing, at sealed plunger 4, one end of valve pressure cap 7 is provided with square type groove 10, the other end is provided with sealing gasket 6, by the protruding 12 moment of rotation type grooves 10 of pressure cap, realizes sealed plunger 4 and drives sealing gasket 6 mobile in valve pocket 11, valve body 1 top of this valving is provided with the attachment cap 9 be connected with SF6 density monitor 3, the bottom of valve body 1 and a side are provided with self-closed joint 2, two self-closed joints 2 and SF6 density monitor 3 are connected by pipeline in valve body 1, the valve pressure cap 7 that screw thread is connected with valve body 1 is provided with in another side of valve body 1, and be provided with O RunddichtringO II 8 between valve body 1 and valve pressure cap 7 and seal, the side that described valve body 1 is connected with valve pressure cap 7 is provided with groove, O RunddichtringO II 8 is positioned at this groove, to realize secondary seal, O RunddichtringO II 8 adopts Ethylene Propylene Terpolymer material, valving sealability is strengthened greatly.The utility model is connected with high-tension switch gear body and adopts self-enclosed structure, when the utility model connects high-tension apparatus body, SF6 gas is connected automatically, when the micro-water measured in high-tension switch gear and tonifying Qi, also self-enclosed structure is adopted, because valve body 1 sealing improves greatly, so the SF6 gas in high-tension switch gear is not to outward leakage, the security of operation of pollution to air and high-tension switch gear can be avoided.
The utility model device is arranged on high-tension switch gear, under normal working, two self-closed joints 2 and SF6 density monitor 3 three connect, when overhauling check and correction SF6 density monitor 3, rotate lower valve pressure cap 7, drive sealed plunger 4 with the protruding 12 moment of rotation type grooves 10 of pressure cap simultaneously, O RunddichtringO I 5 and sealing gasket 6 rotate 180 ° simultaneously, sealing gasket 6 is made to contact with the sealing surface in valve pocket 11 and compress, thus the SF6 gas channel blocked completely in valve body 1, SF6 density monitor 3 is just kept apart with Switch main body thus, then can be verified by self-closed joint 2 pairs of SF6 density monitors 3.Described sealing gasket 6 selects teflon material, and decay resistance is strong.When having verified SF6 density monitor 3, drive sealed plunger 4, O RunddichtringO I 5 and sealing gasket 6 to turn 180 ° to convolution with the protruding 12 moment of rotation type grooves 10 of pressure cap simultaneously simultaneously, contrary with front, the SF6 gas channel of valve body 1 is opened, and device recovers normal working again.
A kind of high sealing SF6 gas valve device described in the utility model, good seal performance, long service life, avoids SF6 gas leakage and pollutes air, ensures the operation that high-voltage switch gear is safe and reliable.
