What is an earthquake?
Earthquake valve automatically closes the natural gas service to the house or business when the earthquake registers at a level or above level that could damage the device. These valves can prevent fires or explosions from gas leakage on the gauge and allow the service to be renewed faster as soon as the danger passes. In some regions that are susceptible to frequent seismic activities, the earthquake is obligatory before the issue of insurance companies. The earthquake valves are usually installed on a pipe that leads from the gas pipeline to the structure.
When the ground moves, movement can damage the main gas line or line connected to the gas equipment. If leaks occur, an electrical spark or an open flame can ignite natural gas, causing an explosion or fire. One study found more than half of all earthquake fires came from natural gas leakage.
The earthquake valve senses the ground movement that activates the shut -off device. One advantage of the valveThe earthquake includes ablites to prevent gas leakage in the free structure. Disadvantages include automatic gas flow disruption when there is no damage to the gas line and there is no leak. After being renewed, it can also invite shocks that could also challenge the earthquake valve to turn off the service to create the need to reset the valve repeatedly.
Excessive flow sensors also work to interrupt the gas service during the earthquake. They work by off the gas when the flow rises above a certain level. These devices are not effective for slow leaks that do not start the closure mechanism. Excessive flow sensors can be installed on the main line coming to the building or on each gas device.
Some people who live in areas susceptible to earthquakes install methane detectors as a preventive measure against gas leakage. Alarm on this device with assetsIt is when the methane gas penetrates through the air, allowing the population to turn off the gas and evacuate. However, someone must be available to hear the alarm and turn off the gas line when these alarms sound. Methane detectors can also cause alarm for other pairs in the air.
During the earthquake, gas appliances could be overthrown or moved and break the strict connection that gives fuel. In some cases, the walls collapse and land on gas lines or meters, causing damage that could cause fire. Mobile homes usually fall from connectors, if they are not properly secured and anchored, gas lines break into residence. Flexible hoses can prevent gas leakage during seismic activity.
gas company experts recommend anchoring all gas appliances, including hot water heaters. If heating sits on an elevated platform, it can move during the earthquake if the platform is unstable. Most gas meters are equipped withENA by manually shutting down the valves designed to interrupt the gas flow using a simple key.
