更換耐震壓力表的小妙招

地震壓力表運行三個月以進行一級維護:檢查三通旋塞和疏水閥接頭,以消除泄漏。檢查壓力表是否可以歸零。檢查并沖洗疏水閥,以確保流量平穩。防震壓力表每年進行一次二次維護:拆卸壓力表,將其送到計量部門進行驗證和密封。

拆卸并檢查疏水閥,螺紋應完好無損。拆卸并檢查三通旋塞,打磨密封面,以確保密封性和無泄漏,連接螺紋應完好無損。集水器,三通旋塞,去除鐵銹和油漆。

使用時更換耐震壓力表:如果發現壓力表在運行過程中未對準,則必須及時更換。 步驟如下:更換的壓力表必須是已通過計量部門校準的鉛封,在驗證期內有效的壓力表或帶有工廠合格證明的新儀表。

更換儀表之前,應將三通旋塞旋入沖洗壓力表的位置,以清潔疏水閥中的污垢。將三通旋塞旋至存水彎的位置。 用扳手卸下舊表,然后換上新表。將三通旋塞轉到正常工作位置,以使新表投入使用。
