进口双重密封波纹管截止阀

进口双重密封波纹管截止阀性能描述 Performance description

波纹管截止阀密封等级为ISO15848-A级，即“零泄漏”，产品内部采用多层波纹管结构，波纹管组件下端采用激光焊接设备焊在阀杆上，组件另一端的密封件置于阀体和阀盖之间，构成金属密封和填料密封的双重密封设计，甚至是多重密封，一改传统阀门动态密封，使波纹管阀门在阀腔内部达到静态密封。The RETZ corrugated pipe globe valve has a sealing grade of ISO15848-A, which is "zero leakage". The product adopts a multi-layer corrugated pipe structure internally. The lower end of the corrugated pipe component is welded to the valve stem using laser welding equipment, and the sealing element at the other end of the component is placed between the valve body and the valve cover, forming a dual sealing design of metal sealing and packing sealing, or even multiple sealing, replacing traditional valve dynamic sealing, Make the bellows valve achieve static sealing inside the valve chamber.

进口双重密封波纹管截止阀主要特点DESIGN FEATURES

波纹管截止阀阀杆波纹管加填料双重密封设计，具有双重保险，使得阀杆处的密封更安全可靠，并符合国际密封标准 The double sealing design of bellows and packing for the valve stem of bellows stop valve has double insurance, which makes the sealing at the valve stem safer and more reliable, and conforms to international sealing standards

阀芯采用锥面密封，密封面不残留杂质，在趋于关闭时，密封面具有自清洁作用。锥形密封面，可以使阀杆轴向力转化为密封力时具有放大作用，密封性能更好 RETZ The valve core is sealed with a conical surface, and the sealing surface is free of impurities. When it tends to close, the sealing surface has a self-cleaning effect. Conical sealing surface can enlarge the axial force of valve stem when it is converted into sealing force, and the sealing performance is better

阀芯结构

锥面密封∶密封面不残留杂质∶在趋于关闭时，密封面具有自清洁作用，实现线性密封 Conical sealing: no impurities remain on the sealing surface: when the sealing surface tends to close, the sealing surface has self-cleaning effect to achieve linear sealing

平衡双阀瓣密封∶小阀瓣缓解压力后带动大阀瓣轻松打开retz品牌 Balanced double disc sealing: small disc releases pressure and drives large disc to open easily

平面软密封∶开启和关闭时软密封表面可防止火花产生，适用于气体介质或耐腐蚀要求的工况 Flat soft seal: the soft seal surface can prevent sparks when opening and closing, and is suitable for working conditions with gas medium or corrosion resistance requirements
