进口角式截止阀性能描述 Performance description

角式截止阀的波纹管加填料双重密封设计，具使得阀杆处的密封更有双重保险，安全可靠，密封面不残阀门采用锥面密封，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，密封性能更佳 RETZ The double sealing design of the corrugated pipe and packing of the angle stop valve makes the sealing at the valve stem more double safe, safe and reliable. The sealing surface does not leave any residue. The valve is sealed with a conical surface, leaving 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.

波纹管的结构 

阀芯结构 Valve core structure

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 

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 retz品牌 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
