HH法蘭直裝差壓液位計_三閥組開關實用特點 在上個世紀80年代就依托原艾默生的羅斯蒙特3051智能金屬電容傳感器技術,獨立自主的集成電路生產(chǎn),提供給眾多化工生產(chǎn),水處理,熱工控制,航空海運,水電核能等各種行業(yè),壓力變送器,差壓變送器,在線式液位計,熱電偶,熱電阻.溫度變送器,水平儀,等高品質(zhì)的優(yōu)秀熱控儀表,
| The three valve group is to connect or cut off the positive and negative pressure chambers of the differential pressure transmitter with the pressure pipe, or to cut off or conduct the positive and negative pressure chambers. In order to equalize the pressure, the positive and negative pressure chambers are protected from too much pressure. The three valve group consists of valve body, two stop valves and one balance valve. In fact, the three valve group is widely used as a common valve. The opening sequence of the three valve group is: opening the positive pressure valve, closing the balance valve and opening the negative pressure valve. The sequence of shutdown is as follows: close negative pressure valve, open balance valve and close positive pressure valve |
HH法蘭直裝差壓液位計_三閥組開關實用打開的順序步驟
上一篇我們就安裝儀表接頭的方法 做了詳細介紹和說明。 本篇文章我們簡單的對 HH法蘭直裝差壓液位計_三閥組開關實用打開的順序步驟 進行描述，作為專業(yè)的截止閥,HH法蘭直裝差壓液位計_三閥組開關實用,儀表接頭生產(chǎn)廠家，讓你了解更多HH法蘭直裝差壓液位計_三閥組開關實用打開的順序步驟，
HH法蘭直裝差壓液位計_三閥組開關實用是將差壓變送器的正負壓室與導壓管導通或切斷，或?qū)⒄搲菏仪袛嗷驅(qū)?。為了均壓，保護正負壓室不受太大的壓力。HH法蘭直裝差壓液位計_三閥組開關實用由閥體、二個截止閥及一個平衡閥組成。 HH法蘭直裝差壓液位計_三閥組開關實用其實應用非常廣泛，是閥門的一種常用閥門。
HH法蘭直裝差壓液位計_三閥組開關實用打開的順序為：打開正壓閥、關閉平衡閥、打開負壓閥。停運的順序為：關閉負壓閥、打開平衡閥、關閉正壓閥。
| 差壓變送器使用中應注意以下三點： （1）差壓變送器在使用前必須對其測量范圍、零點、漂移量、精度、靜壓誤差等進行復核； （2）差壓變送器安裝后，開車之前還需檢查一次各種變送器的工作壓力、工作溫度、測量范圍、漂移量等?？词欠窈蛯嶋H情況相符，若有不符之處，則必須查明原因并糾正后才能開車。 （3）開啟和停用時，應避免差壓變送器承受單向受壓，對每臺差壓變送器應附帶一套三組閥件，通常把三組閥安裝在差壓變送器的上方，其中閥1和閥3分別為高壓和低壓切斷閥，閥2為平衡閥，平衡閥2在開表和停表時，用以保護差壓變送器和便于調(diào)零位。在開啟差壓變送器時，應先打開平衡閥2，然后再打開閥1和閥3，當閥1和閥3全部打開后，再關閉閥2。在停用差壓變送器時，也應先打開平衡閥2，然后再關閉閥1和閥3。按以上順序開啟和停用差壓變送器，可以避免差壓變送器承受單向靜壓而過載。對于有冷凝膠或隔離液的差壓變送器，也可以避免冷凝膠或隔離液被沖跑。

When the flow or differential pressure sensor instrument is connected to the process pipeline, the "three valve group" shall be used to: 1. When the medium is added into the pipeline from the initial state (empty), the pressure on both sides of the sensor will change suddenly. If the pressure difference is too large, the sensor of the transmitter may be damaged. To avoid this problem, close the valves a and B on both sides of the sensor and open the bypass valve C; 2. After the medium fills the pipe and approaches to stability and balance, open one of a or B to apply pressure evenly on both sides of the sensor; 3. Close valve C and open another valve in a or B, and the sensor starts to work normally; 4. The closing sequence is the reverse of the above. In addition, The 3-valve manifold has other functions, such as cleaning the pipeline after running for a period of time, and the sensor part is not affected (the pipeline is bypassed). |
