结构简述

1、弹簧全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。
3、热弹性阀瓣:阀瓣设计为热弹性结构,利用其在介质压力下微小的变形,提高密封能力,克服安全阀在介质压力下临近整定压力时的前泄现象。阀瓣密封面采用先进的激光淬火技术,提高了硬度、耐磨性、抗冲抗性。
4、调节螺母:通过调整调节螺母,调整弹簧压缩量,使阀门能够很方便、很迅速地获得力。

5、背压调整套:调整阀瓣背压的辅助机构,通过背压调整套调整,可获得合适的回座压差。上调时,使阀门背压降低。下调时,使阀门背压提高。
