產品簡介：
按安全閥閥瓣開啟高度可分為微啟式安全閥和全啟式安全閥，全啟式安全閥開啟高度為≤0.25d0(zui小排放喉部口徑)。
微啟式安全閥按結構形式來分，要分為垂錘式、杠桿式、彈簧式和先導式(脈沖式)；按閥體構造來分，可分為封閉式和不封閉式兩種。封閉式安全閥即排除的介質不外泄，全部沿著出口排泄到地點，一般用在有毒和腐蝕性介質中。對于空氣和蒸汽用安全閥，多采用不封閉式安全閥。對于安全閥產品的選用，應按實際密封壓力來確定。對于彈簧式安全閥，在一種公稱壓力(PN)范圍內，具有幾種工作壓力級的彈簧，訂貨時除注明安全閥型號、名稱、介質和溫度外，尚應注明閥體密封壓力，否則按zui大密封壓力供貨。
微啟式與全啟式的區別
全啟式安全閥：當安全閥入口處的靜壓達到設定壓力時，閥瓣迅速上升至zui大高度，zui大限度的排出超壓的物料。一般用于可壓縮流體。閥瓣上升高度不小于喉頸的1/4。
微啟式安全閥：當安全閥入口處的靜壓達到設定壓力時，閥瓣位置隨著入口壓力的升高而成比例的升高，zui大限度的減少應排除物料。一般用于不可壓縮流體。閥瓣的zui大上升高度不小于喉頸的1/20~1/40。
