-
For trouble - free longevity, it is also equipped with a ball check valve which is a third - check member, its main function being to prevent backpressure on each pump cycle from unnecessarily acting directly on the check members
為了保證長期無故障使用壽命，這種裝置還配置球型止回閥作為第三個止回閥元件，它的主要功能在於防止每個泵循環產生的反壓力不必要直接作用在止回閥元件上。 -
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。 -
With its exclusive patented relief valve design incorporating the " air - in / water - out " principle, it provides substantially improved relief valve discharge performance during the emergency conditions of combined backsiphonage and backpressure with both checks fouled
配置獨特專利技術安全閥結構，採用「氣進/水出」原理，當兩個止回閥被污染並且產生反虹吸和反壓力緊急狀況下，這種原理實實在在改善了安全閥的排泄性能。
