加热炉天然气紧急切断阀是风开还是风关? 常减底紧急切断阀? 减压侧线紧急切断阀?

紧急情况下要切断的话就是风开阀,失风就关。

紧急切断的话,在事故状态下,或者停净化风的情况下,应该关闭,属于风开阀,主要根据设备和工艺安全考虑

全是风开?加热炉肯定是的,塔底也是的?

1、风开 2、风开 3、风开
Reply #62017-01-22
既然是紧急切断,那就是气开
Reply #72017-01-23
应该都是风开阀,期设置的根本原则就是紧急状态下,阀门处于的位置来保证整个工艺系统的安全。

都是切断阀,必然是风开阀,故障关

加热炉燃料气应该是风开的,停风事故状态下是关闭的,防止加热炉超温;常底应该是风关的,事故状态下常开,防止减压炉进料中断造成炉管干烧,;减底是风开的,防止事故状态下减压塔液位抽空造成事故;侧线也应该是风关的,事故状态下正常循环取热,防止塔内飞温。

你上面那些回复都没看过吗?

你是没见过sis系统吗?
Reply #122018-08-15
那请教下,你说的具体是哪个切断阀?还是所有都是风关阀?
Reply #132018-08-16
不是具体哪个,是独立的安全系统,一般情况阀门常开不影响工艺操作,事故状态人员一键操作切断关键部位
Reply #142018-08-16
按你的原话,正常工况下常开,事故状态下关闭,选用风关阀门?这样安全吗?
