(旁通阀疏水器)进口带旁通疏水阀 主要性能 Main performance

带旁通吊桶式疏水阀采用内置旁通阀设计，操作时打开旁通阀即可形成旁通回路。特殊设计的关闭系统，阀芯、支架与“超级杠杆”相配合，阀芯在支架内是自由浮动的，避免了关闭时产生的刚性碰撞  RETZ bucket with bypass is designed with a built-in bypass valve for the steam trap, and a bypass circuit can be formed by opening the bypass valve during operation. Specially designed closing system, the valve core and the support are matched with the "super lever", and the valve core is free floating in the support, avoiding rigid collision during closing

特点∶ Performance characteristics

内置自动排空气机构，使通汽初期的低温凝结水和空气迅速排放，缩短了启动时间 The built-in automatic air exhaust mechanism makes the low-temperature condensed water and air in the initial stage of steam flow discharge quickly, shortening the start-up time

内装过滤网，不受杂物影响，可实现无故障工作 RETZ Built in filter screen, not affected by sundries, can achieve trouble free operation

具有双重排放功能,适应水平安装，避免歪斜  Double discharge function, suitable for horizontal installation and avoiding skew

热机使用时勿打开旁路阀，会洩漏蒸汽  Do not open the bypass valve when the heat engine is in use, as steam may leak

不可使用于过热蒸汽 It shall not be used for superheated steam

零件采用不锈钢及硬化阀座材料，耐磨抗蝕 The parts are made of stainless steel and hardened valve seat materials, which are wear-resistant and corrosion-resistant
