产品详情法兰式金属硬密封蝶阀本蝶阀采用的是三维偏心原理设计，是在原有的双偏心基础上增加了一个独特的偏心，不仅利用了原有的凸轮效应，而且完全*了90度旋转中阀板与密封圈之间的全部磨擦。
通过优化了蝶板密封面与阀座密封圈之间接触角的特性，阀门接触角大于锁定锥角范围。
从几何形状看，排除了蝶板卡死的可能性，从而确保阀门开关所需扭矩。
蝶板密封面可以镶不锈钢密封圈或在蝶板上                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              标签：  温州市金属硬密封蝶阀 温州市金属硬密封蝶阀厂家温州市金属硬密封蝶阀厂家供应法兰式金属硬密封蝶阀/温州法兰式金属硬密封蝶阀厂家报价
