An excess flow valve (EFV) is a safety device designed to limit the flow of natural gas to a very small amount if there is a sudden break in your service line. An EFV meeting the performance standards prescribed under 49 CFR Part 192.381 will be installed on all new domestic and commercial service lines where the load is less than 1,000 CFH(每小时立方英尺天然气). Where the load is greater than 1,000年cfh, a curb valve or other service line valve will be fitted.
An EFV is like an 电al circuit breaker that trips when 电al current exceeds a set limit. The EFV will activate when gas flow increases sharply such as when a gas service line breaks. If your service line breaks between the location where the EFV has been installed and your gas meter, the EFV is designed to limit the flow of gas to a very small amount.
xf881兴发手机版公司. 会把它安装在与主电源的连接处吗. It would be installed at the same time your new or modified service line is installed.
是的. The EFV is not designed to close due to slow leaks in your service line, 街道上的煤气总管漏水或破裂, 或者你家管道漏水. The EFV will only shut off the flow of gas due to a break in your service line between the location the EFV was installed and your meter set.
所有xf881兴发手机版公司.’s customers have the option to have an EFV installed on their service line?
This mandatory requirement is for new residential and commercial customers who have service lines that serve a single residences, commerical property and residential and commercial customers who are scheduled for service line modifications, 消耗小于1,000年cfh. The EFV is available to any existing residential customer upon request and at cost. Service isolation valves will be fitted on commercial/industrial services with a load greater than 1,000年cfh.
If you are having a new or modified service (if appropriate) line installed, the installation cost is included in the service cost you will be quoted. Under normal circumstances there should be no required maintenance on an EFV.
No. Earthquake valves are designed to shut off if seismic activity above a certain level is detected. An EFV will only limit the flow of gas due to a sudden increase in gas flow, 例如当服务线路中断时.
Are there other options that provide protection against service line breaks?
是的. The most common cause of a service line break is third party damage, so "挖掘之前先打个电话" at least two business days prior to any excavation.
气体, 电, 水, telecommunications and sewer lines are just some of the utilities buried underground, 有时在很浅的深度. Before you move dirt for any reason – installing a sprinkler system, 建立一个棚, even planting a tree – you should call Kansas One Call by dialing 811. 当你打电话提前两个工作日挖掘, crews will locate and mark all underground utilities at no charge to you. 通过了解地下有什么, you can save yourself the 头疼 and expense of repairing any utility lines you could damage by digging into them.
一氧化碳, 通常被称为有限公司, 是有毒的, 没有气味的, 无色, 无味的, 和无刺激性气体. CO is formed by incomplete combustion, and when inhaled by people or pets, it can be fatal.
停放的车辆是一氧化碳中毒最常见的来源. Natural gas appliances account for a small percentage of all CO poisonings, particularly space heating equipment in where vents and chimneys are not properly installed or maintained. Other causes include misuse of appliances such as improper use of ranges and ovens for space heating.
接触到高浓度一氧化碳的人可能会出现头晕, 头疼, 恶心想吐, 嗜睡或其他类似流感的症状，但没有发烧. 如果你有这些症状, evacuate people and pets from the building immediately and call 911 or Midwest Energy, at 1-.
