    产品描述
产品结构特点:
(1)、阀座与阀体为可分离式,维修方便.经济 .
(2)、 伞形反冲盘能够有效提高升力,阀瓣在较小压力下就能够迅速开启,排放介质,从而达到保护设备的目的
(3)、 调节圈能够调节满意的启闭压差。
(4) 、 对反冲盘和导向套.阀杆和调整螺丝钉的材料进行合理的选择以及间隙的适当选取,保证阀瓣运动灵活。
(5)、 阀瓣.阀座密封面对焊硬质合金,表面精研后保证高密封和使用寿命。
(6) 、 波纹管安全阀中的波纹管能够消除背压波动对阀门性能的影响,还能保护弹簧和其他内件免受介质的腐蚀。
本阀门适用于工作温度≤200℃存在不稳定背压或有毒、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≤4MPa采用JB/T6……94系列1。>4MPa采用JB/T……94系列2标准。
