A flapper-type gas valve automatically closable by accelerations characteristic of earthquakes. The arm is held up in the valve open position by a magnet attracting a soft ferromagnetic armature. The armature can be displaced to release the flapper to close the valve, either by seismic ...
Earthquake Valve Specialists protect your home with the installation of an automatic gas shut off device
The present invention discloses an automatic gas shut-off valve which has associated therewith a seismic sensor unit. The seismic sensor unit can be either an electric unit or mechanical unit or both. In operation, the seismic sensor is triggered by a seismic event to the dump/default or ...
[Effect] closes automatically as soon valve and setting seismic intensity more earthquake occurs, it is possible to Bosaegi a fire accident caused by the earthquake can be reliably and completely automatic shut off the gas to accurately. And in particular the valve body 11 in sliding misalignment...

And in particular the valve body 11 in sliding misalignment...
off vibration value or seismic intensity required for shut off operation to be adjustable by making it possible to replace a small ball which detects vibration or rolls when an automatic shut off valve is applied to detect a specific vibration and automatically shuts off fluids such as gas, etc...
A gas flow shut-off valve that senses seismic motion inducing oscillating ball movement in a concave dish of a lateral valve chamber. When the intensity of seismic shaking reaches a destructive level, the ball valve is dislodged from the dish into a valve seat, thus blocking the gas flow ...
