JLL-BJ41W保温截止阀
JLL-BJ41W保温截止阀
产品概述 Product Description
BJ41W保温截止阀主要应用于化工、石油、制药、冶金等行业的系统管路中，主要作用是输送在常温状态下会凝固、易结晶的介质。夹套保温截止阀两法兰之间焊装有金属夹套，在截止阀的侧面和底部设置了夹套接口，用于注入蒸汽或其它保温、保冷介质，确保阀内介质能够正常工作。夹套保温截止阀的连接法兰相较于普通截止阀要大一至两个规格。
工作原理 Working principle
BJ41W保温截止阀是原有的截止阀两端法兰之间焊装一个金属夹套，侧面两边装有夹套的连接口，用于蒸汽或导热油的进出。从而起到对截止阀内部介质的保温效果，确保粘稠介质流通正常。直通保温截止阀主要应用于化工、石油、沥青、制药、冶金等行业的系统管路中，主要作用是输送在常温状态下会凝固、易结晶的介质。
