Shut-off Valve for Integration into a Gas Meter |
| 摘要 |
A shut-off valve for integration into an intelligent gas meter for residential or industrial gas supply, has an inlet, an outlet and a valve seat having a lip seal. A shut-off body is longitudinally displaceable with respect to the valve by a motor driven transmission, using a nut-threaded-spindle drive, to engage with or disengage from, the seal to open or close the valve. The transmission of the valve remains largely unbiased in the closed state while maintaining the gas-tightness of the valve. |
