      針型閥是一種可以調整的閥門,用途較廣,比如火焰切割用的割距,調整火焰溫度的旋鈕就是針型閥。我們大家在安裝針型閥的時候,大家知道怎樣安裝針型閥?
 
      針型閥安裝位置、高度、進出口方向須符合設計要求,注意介質流動的方向應與閥體所標箭頭方向一致,連接應牢固緊密。針型閥安裝前須進行外觀檢查,閥門的銘牌應符合現行國家標準《通用閥門標志》GB 12220的規定。對于工作壓力大于1.0 MPa 及在主干管上起到切斷作用的閥門,安裝前應進行強度和嚴密性能試驗,合格后方準使用。強度試驗時,試驗壓力為公稱壓力的1.5倍,持續時間不少于5min,閥門殼體、填料應無滲漏為合格。
針型閥
     針型閥是儀表測量管路系統中重要組成部分,主要有截止閥和球閥,其功用是作開啟或切斷管道通路用。我們大家在安裝我們這些針型閥的時候,我們都可以按照上面的安裝方法去安裝使用我們這種針型閥。
