RETZ瑞茨『进口波纹管截止阀』详细介绍●RETZ截止阀系列●RETZ波纹管截止阀●产品数据
?进口波纹管截止阀描述--
1.波纹管密封截止阀其关键部件—金属波纹管，采用的是内藏式波纹管，免冲刷设计，另采用多层结构，通过液压成形可保证的寿命延长，免维修，降低运行成本。
2.下端与阀杆组件采用自动滚焊焊接，在流体介质和大气之间形成一个金属屏障，阀瓣与阀体密封面采用行星式自动变频研磨，组装完毕经过100%试压，确保阀杆零泄漏。作为辅助密封，在波纹管上面依然保留了填料函，填料一般为带缓蚀剂的编织石墨，更增加了可靠性、安全性以及耐高温性，提供一个无需维护的条件。
3.独特的流道设计，采用计算机模拟验证，减小气蚀，实行全通，比同样的流道能力增加10%一50%，流阻系数比同类阀门低，相同条件下流量大压差小，能源消耗降化，提供用户经济绿色的产品。
1. the key part of the bellows sealing cut-off valve, the metal bellows, is used in the inner Tibetan bellows, the design is free of scour, and the multi-layer structure is adopted. Through the hydroforming, the maximum life span, the maintenance free and the operation cost can be avoided.
2. the lower end and the stem components are automatically rolled and welded to form a metal barrier between the fluid medium and the atmosphere. The valve and the valve body seal face adopts the planetary automatic frequency conversion grinding, and the assembly is finished after 100% pressure testing to ensure the valve stem's zero leakage. As an auxiliary seal, the packing letter is still retained on the bellows. The packing is usually woven graphite with a corrosion inhibitor, which increases reliability, safety and high temperature resistance, and provides a condition without maintenance.
3. the unique flow path design, using computer simulation verification, reduce cavitation erosion, implement full pass, increase 10% to 50% than the same flow capacity, flow resistance coefficient lower than the same type valve, under the same condition, the flow of large pressure difference, energy consumption minimization, to provide a green product of the user.
?进口波纹管截止阀特点--
1.独特的流道设计
比同规格的流道能力增加10%一50%，流阻系数低。
2.堆焊、研磨加工的阀瓣
采用不锈钢材料和耐腐蚀合金钢。焊接材料是的Stellite(司太立)6#，增加耐腐蚀、耐冲刷，增加寿命，同时保护密封圈的使用。
3.道密封一一波纹管组件
采用内藏式设计，免冲刷，免维修，降低运行成本，使用寿命长。
4.第二道密封一一非金属填料
使用带缓蚀剂的编织填料，更增加了可靠性、安全性以及耐高温性提供一个无需维护的条件。
5.防转块
防止波纹管的横向扭转确保波纹管使用寿命的性。
6.填料压套
用于压紧填料使密封性能更完好，增加填料的使用寿命，免维护。
7.内限位装置
增加阀杆的上限位，保护阀门的使用安全，有效的保护波纹管的弹性变量，大大提高使用寿命。
8.铰链式连接
阀瓣和下阀杆采用的是铰链式连接，王要是为了密封区接触处的密封吻合度使密封性能更可靠保证关闭时无泄露
