INTERNALLY POWERED EARTHQUAKE TRIGGERED AND ELECTRICALLY CONTROLLABLE SHUTOFF VALVE An earthquake triggered and electronically controlled shutoff valve for allowing or preventing a flow of a fluid. The shutoff valve incorporates a weight positioned on a pedestal and disengaged from a surrounding moveable ...
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 pressure control for a shut-off valve, preferably an earthquake sensitive shut-off valve, and a control for closing the valve in response to regulated pressure failure in the pressure supply of gas or the like thereto, and including a meter means or the like upstream, the control sensing ...
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, ...
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...
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. ...
qualify the operability of (1) electrical equipment, their components, instruments, and controls, and (2) active mechanical equipment. In a few cases the test can be static, such as applying a static lateral force to a valve operator to check the strength of the valve-operator-to-body ...
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 FLOLOC is our industry’s most proven and reliable manufactured seismic control equipment. A FLOLOC is the only complete and integrated Seismic Control System with the necessary torque to close a valve in a broken pipeline.
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. ...
