三閥組的安裝、拆卸及使用方法

Three?Valves?mounting,?disassembly?and?method?of?application

安裝?Mounting

拆卸?Disassembly

1.?正常使用差壓表必須配三閥組或五閥組以保護差壓表正常工作。

2.?差壓表和三閥組用兩個索母緊固。索母和差壓表接頭密封面應加四氟墊片。

3.?裝有三閥組的差壓表在使用前必須把中間閥門打開，并把正壓閥門和負壓閥門打

開。（當?P+和?P-?任意的壓力**入時，中間閥門能起到平衡差壓表兩腔體內的壓

力的作用，以免打壞差壓表。）

4.?當P+、P-的壓力正常進入三閥組后，再關閉中間閥門使差壓表正常工作。如差

壓表表針有輕微離零屬正常，只需把表針調到零位即可（注意必須用肥皂水檢驗所

有密封口是否泄露，如有泄露必須緊固。）

5.?差壓表有后背板式安裝（如圖）和立管固定方法。（管卡子卡到管子上）。

1.?Use?differential?gauge?must?fit?out?three?valves?in?order?to?insure?it’s?normal

5.?The?differential?pressure?gauge?has?back?plate?mounting?(see?the?chart)?and

standpipe?fixed?(the?pipe?with?clamp).

1.?首先打開三閥組的中間閥門。并打開正壓和負壓閥門（正壓負壓閥門原始為打開）

2.?關閉總進氣的兩個閥門。（在設備的主管道上）

3.?拆下更換儀表（卸兩個索母）注意用扳子卡住差壓表的接頭，只拆三閥組上的上

索母。先松開一點放空壓力，再把卡到管子上的卡子螺母松掉，并把卡子拿下。

4.?再把三閥組上的兩個索母慢慢松開把差壓表取下。?（注意一定要兩個索母同時松）

5.?把新表裝上的方法同上面安裝方法**換上兩個新的四氟墊（確保不漏）

6.?把卡子卡好

7.?先開總開關（兩個），再關上差壓表三閥組中間的閥門（新接口用肥皂水試漏）。

8.?兩分鐘后把差壓表表針調到零位。（如沒有輕微離零不用調整）

注：在裝表或卸表時，必須保證中間閥門和P+、P-兩個閥門全部開啟，以確保儀表能正常使用。
