产品简介：
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，全启式安全阀开启高度为≤0.25d0(zui小排放喉部口径)。
微启式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。
微启式与全启式的区别
全启式安全阀：当安全阀入口处的静压达到设定压力时，阀瓣迅速上升至zui大高度，zui大限度的排出超压的物料。一般用于可压缩流体。阀瓣上升高度不小于喉颈的1/4。
微启式安全阀：当安全阀入口处的静压达到设定压力时，阀瓣位置随着入口压力的升高而成比例的升高，zui大限度的减少应排除物料。一般用于不可压缩流体。阀瓣的zui大上升高度不小于喉颈的1/20~1/40。
