The shut-off device and the trigger device are connected through the valve cock. The gas earthquake shut-off valve can quickly and accurately shut off gas when an earthquake happens, and is simple in structure and low in manufacturing cost.王翔宇...
A gas shut-off valve is provided for closing off a natural gas pipeline in the event of an earthquake or other seismic disturbance. The valve has an inlet and an outlet aperture communicating with a central chamber, and a valve seat provided between the inlet and the outlet apertures. An ...
An earthquake actuated automatic gas shutoff valve having a valve bottom portion with a generally horizontal floor having a ball seat and a valve seat surrounding a gas outlet passageway. A ball having an elastomeric outer surface is held in the ball seat and in the event of an earthquake, ...
Examine all utility lines. If you smell gas, air the facility by opening the windows and switching off the main gas valve. Also check any appliances for damage. Also examine sewage lines and plumbing to check that they are intact and working. Check all electrical wires, if any are shorting...
Shut off Utilities Leaking natural gas can cause a fire or explosion. If you have the reason to believe that an earthquake is coming, make sure you know how to turn off your gas supply. The main gas valve is always located outside, next to the meter box. The same goes for the main...
(or active function) applies to components that must change state during or after the earthquake. This is the case for all SC-I electrical equipment and instrumentation and controls. It is also the case for certain SC-I mechanical equipment such as pumps, compressors, fans, and valve ...
An electromechanical shut off valve 15 shuts off gas and liquid supplies. Multiple shut off valves in a piping system would allow for the isolation of broken sections, minimizing material loss and allowing limited operation immediately after the earthquake. ...
How does it work? When an earthquake strikes, FLO-LOC actuates valves to close immediately and intelligently, thus safeguarding the millions of gallons of water, chemicals, sewage, oil, or gas in storage and in pipelines. FLO-LOC can also activate pumps off and on, shut down power, activat...
For instance, in protecting a gas or oil line one must take into account the speed at which a valve can seal the pipe.ConclusionsIt is reasonable to consider that a low-cost seismic detection system can be designed using tried-and-true high-performance digital signal processing plus the...
A gas shut-off valve is provided for closing off a natural gas pipeline in the event of an earthquake or other seismic disturbance. The valve has an inlet and an outlet aperture communicating with a central chamber, and a valve seat provided between the inlet and the outlet apertures. An ...
