pullaway valves 拉断阀

当车辆连接LNG 加液枪却意外驶离加注站时，我们的紧急拉断阀具有自动切断液化天然气（LNG）的设计。此外，如果LNG加液软管与 LNG 加液枪被强制拉离加注站时，紧急拉断阀可防止加注站设备的损毁．紧急拉断阀是一种什么阀门？主要用在哪些方面？紧急拉断阀是一种用在油品、天燃气等易燃易爆物品上的一种快速拉断阀。 它主要工作原理是流体是装卸作业时，如果突然发生火灾、泄漏等事故时，在现场的工作人员能迅速拉断作业车，逃离现场。而流体又不造成泄漏。这样能减少很大损失。又保证了人身安全。 afety Breakaway Couplings The Safety breakaway couplings consists of two halves, each with a poppet that has a flat type-sealing surface similar to a dry disconnect coupling. The coupling remains constantly open under normal use. The two halves of the breakaway coupling only close when there is excessive force, such as in a truck or railcar drive away situation. When the couplings separate, this allows the poppets to close. Product loss is minimized because the two poppets close rapidly, minimizing exposure to personnel and the environment.
