blowout preventer

基本解釋

First, remote-controlled robot submarines have been deployed to try to seal off the oil well altogether by activating a massive device called a blowout preventer.
首先，他們已經(jīng)部署了遙控機器人駕駛的潛水艇潛入水下試圖通過激活防噴器來關(guān)閉油井。
As the first diagram shows, the main component would be a containment assembly that could fit on top of a damaged blowout preventer, such as the one from which the Macondo oil poured forth.
如第一張圖解所示，主要部件是能安裝在一個受損的防噴器頂端的一個封存裝置，例如馬貢多井的原油就是通過防噴器涌出。
If the rate is at the low end of the range and was lower still before a key pipe on top of the blowout preventer was cut to accommodate the top hat, about half as much oil has been spilled so far.
假如現(xiàn)在這個比率是最低的、并且放在防噴器上方的關(guān)鍵性管道適應(yīng)了高帽之前、仍然保持低比率，那時候泄漏的油約相當(dāng)于現(xiàn)在已經(jīng)漏掉量的一半。

The cap installed on the top of the well is basically a second blowout preventer.
