冷水機組閥門安裝七大注意事項

2022-10-16

1. 閥門的安裝位置應便于拆卸和維修。安裝各種閥門時,要注意制冷劑流向,不能倒裝

2. 安裝工業冷水機組法蘭閥門時,法蘭和閥門法蘭必須填充高壓石棉片。高壓石棉板的厚度應根據閥門上法蘭槽的深度確定。當閥門較大且槽較深時,厚石棉板應使用,避免凹凸縫間的縫隙和密封松動。裝配法蘭閥時,所有螺栓受力必須均勻,否則凹凸界面容易偏轉。

3.安裝截止閥時,工作流體應從閥門底部流向頂部。安裝在水平管道上時,閥桿應垂直向上或以一定角度傾斜,閥桿不得向下。當閥門位置難以接近或更高時,可將閥桿水平安裝,便于操作

4. 在工業冷水機組上安裝止回閥時,閥芯應能自動開啟。對于升降式止回閥,閥芯中心線與水平面應相互垂直。旋啟式止回閥應保證閥芯板的轉動,閥芯板必須水平安裝。

5. 安全閥應直接安裝在設備出口處的截止閥上,閥體上的箭頭應與工作介質的流向一致。

6. 電磁閥必須水平安裝在設備出水口,安裝在圖紙規定的位置。如果電磁閥安裝在節流閥前面,兩者之間的距離應至少為300mm。
