迴流閥
  • backflow : 倒流
  • valve : n 1 【機械工程】閥，活門，舌門；汽門。2 【解剖學；動物學】瓣，瓣膜；（貝）殼瓣；【植物；植物學】...
  1. Air braking systems ; shuttle valve with backflow

    氣壓制動系統.迴流循環閥
  2. For use with backflow preventers, isolation valve for gauges, isolation valves for small equipment lines

    用於防迴流閥，用於儀表的隔離閥，用於小型設備管道的隔離閥。
  3. A check valve may be required ahead of the backflow preventer

    此時在防迴流閥前面可能需要安裝一個止回閥。
  4. The shutoff valve with the test cock is to be mounted on the inlet side of the backflow preventer

    帶測試旋塞的關閉閥應該安裝在防迴流閥的進口側。
  5. Therefore, if both check valves foul, and simultaneous negative supply and positive backpressure develops, the relief valve uses the air - in / water - out principle to stop potential backflow

    因此，如果兩個止回閥都受到污染，並且同時出現負供應壓力和正反壓力，則這種安全閥就利用氣進/水出原理來阻止潛在的迴流。
  6. Dual check valve type backflow preventers

    雙重止回閥型防迴流裝置
  7. To avoid this discharge, install a spring - loaded, rubber seated check valve ahead of the backflow assembly

    為了避免這種排放，要在防迴流閥總成前面安裝一個彈簧驅動、橡膠閥座的止回閥。
  8. Non - return ( stop - check ) valves provide the same function as a globe valve with the addition of providing piston - lift - check valve protection in the event of backflow

    逆止閥（截止止回閥）具有與截止閥相同的功能，還有活塞提升式止回閥的功能，防止出現意外的迴流。
  9. If relief valve discharge due to a failure of the backflow preventer second check valve is a concern, a second flood protection - shutdown valve should be located immediately downstream of the backflow prevention assembly

    如果認為防迴流閥的第二止回閥的故障導致安全閥排放現象應該得到處理，則應該在防迴流閥總成下游立即安置第二堵漏-關閉閥。
  10. The system should be flushed before the backflow valve is installed

    在安裝迴流閥之前系統應該進行沖刷。
  11. If the system is not flushed until after the backflow valve is installed, remove both check modules from the valve and open the inlet shutoff to allow water to flow for a sufficient time to flush debris from the water line

    如果在安裝迴流閥之前系統還為沖洗，則從閥門上拆卸兩個止回閥模塊，開啟進口關閉閥，讓水流過足夠長的時間來沖洗水管內的堆積物。
  12. Double check valve backflow - prevention assembly

    雙止回閥防迴流組件
  13. Note : for australia and new zealand, line strainers should be installed between the upstream shutoff valve and the inlet of the backflow preventer

    注意：適用於澳大利亞和紐西蘭：管路過濾器應該安裝在上游關閉閥和防迴流閥進口之間。
  14. To avoid this discharge, install a spring - loaded check valve ahead of the backflow assembly to " lock - in " the downstream pressure

    如果放置在坑內，則應該採取措施使得排放總是在地面上，或對于坑內排放，要確保在安全閥下方配置一個適當的氣隙。
  15. The national fire protection agency ( nfpa ) guidelines require a confirming flow test to be conducted whenever a " main line " valve such as the shutoff valves or a backflow assembly have been operated

    美國國家防火協會（ nfpa ）指導原則要求對于主管線上運行的閥門，如關閉閥或防迴流閥總成，必須進行流量測試。
  16. Fire protection system installations : the national fire protection agency ( nfpa ) guidelines require a confirming flow test be conducted whenever a " main line " valve such as the shutoff valves or a backflow assembly have been operated

    消防系統安裝：美國國家消防局（ nfpa ）指導原則要求只要是「主管線」上已經運行的閥門，如關閉閥或防迴流閥總成，都需要進行流量確認檢測。
  17. Fire protection system installations : the national fire protection agency ( nfpa ) guidelines require a confirming flow test be conducted by a certified tester whenever a " main line " valve is installed, such as a shut - off valve or a backflow preventer

    消防系統安裝：美國全國消防局（ nfpa ）指導方針要求在安裝「主管道」閥門時要由有資格證書的檢驗員對關閉閥或防迴流閥進行流量檢測。
