不锈钢安全阀
产品简介
详细信息
不锈钢安全阀是一种安全保护用阀,按安全阀阀瓣开启高度可分为微启式安全阀和全启式安全阀,微启式安全阀的开启行程高度为:≤0.05d0(zui小排放喉部口径);全启式安全阀开启高度为≤0.25d0(zui小排放喉部口径)。
不锈钢安全阀按结构形式来分,要分为垂锤式、杠杆式、弹簧式和先导式(脉冲式);按阀体构造来分,可分为封闭式和不封闭式两种。封闭式安全阀即排除的介质不外泄,全部沿着出口排泄到地点,一般用在有毒和腐蚀性介质中。对于空气和蒸汽用安全阀,多采用不封闭式安全阀。对于安全阀产品的选用,应按实际密封压力来确定。对于弹簧式安全阀,在一种公称压力(PN)范围内,具有几种工作压力级的弹簧,订货时除注明安全阀型号、名称、介质和温度外,尚应注明阀体密封压力,否则按zui大密封压力供货。
