品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……(大排量)进口双阀座蒸汽疏水阀适用于大型蒸汽设备，压力波动较大或容易产生大量凝结水的场合，如各种蒸汽管网、加热设备、烘干设备、伴热设备、石油化工蒸馏塔设备等retz (Large displacement) imported double seat steam trap valve is suitable for large steam equipment, occasions with large pressure fluctuations or prone to producing a large amount of condensate, such as various steam pipe networks, heating equipment, drying equipment, heat tracing equipment, petrochemical distillation tower equipment, etc

进口双阀座蒸汽疏水阀主要性能 Main performance

双阀座大排量蒸汽疏水阀在冷凝水轻或重的负荷下工作都十分有效率，它们的排水量持续且高效，***大的热传递。此类阀门是带自动温度控制排水装置的好选择  RETZ  Double seat large displacement steam traps work very efficiently under light or heavy load of condensed water. Their drainage capacity is continuous and efficient, ensuring maximum heat transfer. This type of valve is the best choice with automatic temperature control drainage device.

进口双阀座蒸汽疏水阀特点∶ Performance characteristics

平衡双阀座设计，与同类的疏水阀相比体积小排量大，在需要大排量排除凝结水的工况，更能充分显示其优越的性能  RETZ The 进口双阀座大排量蒸汽疏水阀3.jpgbalanced double valve seat design, compared with similar drain valves, is small in volume and large in displacement, and can fully display its superior performance under the condition that large displacement is required to discharge condensate

阀体内设防冲蚀挡板，耐水锤震动 Anti erosion baffle is set in the valve body to resist water hammer vibration

背压率大于90%，便于凝结水回收 The back pressure rate is greater than 90%, which is convenient for condensate recovery

内置自动排空气装置，启动迅速，无空气气堵，排除不可凝结气体性能好，可在线更换 Built in automatic air exhaust device, quick start, no air blockage, good performance of removing non condensable gas, and online replacement

排水阀座孔始终在凝结水水位以下，形成水封，工作时无新鲜蒸汽泄漏 The drain valve seat hole is always below the condensate water level, forming a water seal, and there is no fresh steam leakage during operation
