企業用的冷水機組閥門的安裝流程分析

2022-11-08

    在工業冷水機組的制冷系統中,閥門的主要作用是控制制冷劑的流量和流向。在日常使用中,閥門也需要經常使用。當工業冷水機需要關閉或開啟時,需要使用閥門。由于其日常使用頻率較高,應更加注意其安裝,以保證其正常使用,而不影響工業冷水機的穩定性。帶大家了解一下工業冷水機組制冷系統中閥門的安裝步驟和注意事項。

1. 閥門應安裝在便于拆卸和維護的地方,安裝各種閥門時必須注意制冷劑流向。不允許反向安裝。

2. 工業冷水機組安裝法蘭閥門時,法蘭和閥門的法蘭必須用高壓石棉板墊緊。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,槽較深時,厚石棉板應使用,以避免它們之間的凹凸接縫容易有縫隙,密封不嚴密。裝配法蘭閥時,所有螺栓受力必須均勻,否則,凹凸界面容易偏斜。

3.在安裝截止閥時,工作流體應從閥門底部流向頂部。安裝在水平管道上時,閥桿應垂直向上或有一定角度傾斜,閥桿不得向下。如果閥門位置難以接近或較高,可將閥桿水平安裝,方便操作。

4. 安裝工業冷水機組止回閥時,確保閥芯能自動打開。對于升降式止回閥,應保證閥芯中心線垂直于水平面。對于旋啟式止回閥,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口,必須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。
