                                        管線全焊接球閥的測試方法

                                        2016-09-30 0

                                        為確保閥門自身的安全性能與密封性能,在安裝管線全焊接球閥(直埋式全焊接球閥)之前必須進行相關的壓力試驗。今天就來為大家簡單講解對應的閥門嚴密試驗及強度試驗的方法:

                                        1、焊接球閥的嚴密試驗:

                                        嚴密試驗采用氮氣作介質;將球閥關閉.從袖管上試壓閥門向球閥內注入氮氣.壓力升至球閥公稱壓力的1.1倍,中腔放壓閥接軟管通人盛水容器進行檢測.插入深度為1cm;5min內無氣泡產生為合格。

                                        2、閥門強度試驗:

                                        強度試驗采用水作介質;在閥門兩側袖管上焊接高壓—咄帽.將閥門開至45℃位置后,通過袖管上的試壓閥門向球閥內注入水.升壓至球閥公稱壓力的1.5倍,保壓15min;無泄漏為合格。

                                        以上就是關于管線全焊接球閥的測試方法,深圳億威仕專業生產管線全焊接球閥的測試、檢測設備,如閥門強度試驗機、閥門密封性能試驗機等閥門性能測試設備,歡迎來電咨詢。電話:0755-8889 8859.
