安全阀

If global air-failure and valve is kept as FC, steam to reboiler will fail close, reflux will fail open, hence likely that safety valve will not blow.

如果整体气源中断，而阀保持故障关，到再沸器的蒸汽将故障关闭，回流将故障打开，因此有可能安全阀不会打开泄放。

Safety valve along with its outlet piping and downstream piping of such valves as steam blow off valve,vent and drain valve,shall not be not insulated,unless otherwise specified.

如无规定，配有安全阀的外泄管道和蒸汽管道，下水管道 4。

In the light of the problems with imported offshore wellhead, such as being bulky and expensive and being inconvenient to mount and maintain, Model HKY65―21 offshore wellhead is developed. This wellhead consists of tubing head assembly, PHK plate gate valve, safety valve, stop valve, clamp, small four-way connection and choke, and it is small-sized, light-weighted, high-strength, corrosion- and abrasion-resistant, reliably sealed and convenient to mount and maintain. Application shows that the wellhead can satisfy the requirements of offshore production with good performance.

针对海上油田所用国外采油井口装置存在体积庞大笨重、价格昂贵以及与国产设施不配套和安装维护不便等问题，研制了HKY65―21型海上井口装置这种井口装置主要由油管头总成、PHK平板闸阀、井口安全阀、截止阀、卡箍总成、小四通和节流器组成，具有体积小、重量轻、强度高、防腐耐磨、密封可靠和安装维护方便等优点现场使用128套的实践表明，其各项技术性能指标均能满足海洋石油生产的要求，完全可以取代进口产品，经济效益可观

In this month's installment, we'll be discussing the pilot relief valve and compare its operation and application to the direct-acting valve.

在这个月的分期付款阀门，我们将讨论试验安全阀并比较其操作和应用的直接作用。

In the May 2004 and July 2004 "Shop Talk" articles, we mentioned the Safety Relief Valves direct-acting relief valve, the simplest relief valve used.

在2004年5月和2004年7月&店谈话&中，我们提到了直接作用减压阀，安全阀使用最简单的。
