                                        減壓閥性能壓力試驗方法的一般要求

                                        2015-10-16 0

                                        減壓閥性能壓力試驗方法的一般要求

                                        1、對試驗目的、試驗場所、試驗介質、測量方法、測試手段和設備,應盡量符合產品的實際工況,使之基本反映出產品的性能。在實驗前,應與有關方面協商達成協議。

                                        2、監督試驗人員應具備流量測量實際經驗,并在試驗進行過程中始終在場。

                                        3、試驗應按第七章規定作出試驗報告。經監督試驗人員簽字和有關單位蓋章方可生效。

                                        4、試驗進行中不應對閥門作任何調整,當試驗條件發生變化或偏離時,可以從新進行調整,但不得更換零件。

                                        5、試驗管道應與被測閥通道相同

                                        6、性能試驗系統示意圖如圖1所示
