弹簧微启式安全阀产品特点:
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。
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、很迅速地获得准确的整定压力。
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。
