信息标签:DA42Y-16P不锈钢低温安全阀,供应,机械及行业设备,阀门
适用于工作温度≤300℃的石油气、空气、水等介质的设备或管路上。型适用于工作温度≤200℃有腐蚀性介质的设备或管路上,作为超压保护装置。连接法兰标准按jb/t……94/系列。
二、结构简述:
1、弹簧微启式安全阀具有结构简单、密封性能好、开启压力准确、排放能力大、回座压差小、调整方便等特点。
2、喷嘴型阀座:阀座为位伐尔喷嘴型阀座,蒸汽流经阀座出口处时达到音速,排放系数大,阀座密封面 堆 焊钴铬钨硬质合金,耐磨抗冲蚀,寿命长。
三、安装说明:
1、安全阀必须垂直安装,并**直接安装在容器或管道的接头上。接头内径应不小于安全阀的进口通径。
2、安全阀的出口必须装设适当的膨胀节,以防止排放管的热膨胀给安全阀带来不应有的热应力。排放管内径应比阀门出口直径大,长度尽可能短,避免拐弯。排
