Automatic switching-off type valve device and gas equipment

The invention provides an automatic switching-off type valve device and gas equipment, and belongs to automation fields. The automatic switching-off type valve device and gas equipment can be automatically switched off when violet vibration exists outside. The valve device comprises a fixing frame, a valve, a driving mechanism, a locking mechanism, an unlocking mechanism and a sensing mechanism. The fixing frame is connected with the ground and used for fixing parts. The valve comprises a valve plate and a valve body, the valve plate is arranged in the valve body, and the valve can be switchedon or off by pulling the valve plate by the driving mechanism. The locking mechanism is used for locking the driving mechanism, and the valve is kept in a switched-on state under the normal condition. The sensing mechanism is used for sensing the violet vibration and unlocking the driving mechanism through the unlocking mechanism. Thus, the automatic switching-off type valve device and gas equipment can be automatically
