具体实施方式
下面将结合附图对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例1，如图1至图2所示：
一种高性能蝶阀，包括阀体1及其顶端的手柄12，阀体1内设有凹槽燕尾型阀座3，凹槽燕尾型阀座3内设有轴套，轴套内设有阀轴5，凹槽燕尾型阀座3上下端面分别设有支撑环，凹槽燕尾型阀座3设有阀板4，阀轴5连接轴销9，轴销9顶端设有齿盘11，齿盘11顶端连接手柄12。
本实施例的一种优选技术方案，轴套采用钢制且内孔喷涂PTFE，其包括三个部分，分别为轴套一2、轴套二6及轴套三8，轴套一2位于凹槽燕尾型阀座3内，轴套三8位于轴销9与阀轴5连接处。
本实施例的一种优选技术方案，齿盘11与手柄12连接。
本实施例的一种优选技术方案，手柄12顶点还设有手柄顶丝13。
本实施例的一种优选技术方案，阀轴5与轴销9连接处还设有O型圈。
在本实施例中，所用部件均为通用标准件或本领域技术人员知晓的部件、其结构和原理都为本技术人员均可通过技术手册得知或通过常规实验方法获知。
橡胶阀座采用凹槽燕尾型设计，凹槽使阀座固定阀体上，启闭时阀座不移动。燕尾式间隙设计在安装压紧时可向燕尾空隙处挤压，不挤压阀座与蝶板接触面，保持固定的过盈量，不会增大摩擦力，从而减小蝶板转动的扭矩。
橡胶阀座上下端面支撑环设计，有效的防止橡胶在温度变化情况下橡胶的收缩和膨胀，保证端面及轴孔的密封性能。
阀杆套采用钢制内孔喷PTFE，减小阀杆转动时的摩擦力和吸收轴向力，从而减小了阀门的扭矩。
阀体、阀板采用精加工，由传统的普通车床加工改为数控专业车床，提高了加工精度，阀板端面和密封面精加工后，增加了镜面抛光，提高了光洁度和润滑度，使阀板和阀座配合过盈量减小，降低了扭矩，提高了产品的使用寿命。
阀杆表面加工后，在原先的无心研磨的基础上增加了冷轧工艺，使阀杆表面光滑紧实，提高了光洁度，从而达到最小扭矩和最长的使用寿命。
采用无销防阀杆脱出结构，提高了产品的使用性能。
当需要安装时：阀门的阀板微开，阀板在阀体内，将阀门插入两侧法兰中间，不用再加法兰垫片。安装螺栓，暂不锁紧，打开阀板至全开位置，检查阀板开启关闭是否顺畅，无异常，将螺栓锁紧，再操作开关一次，确认能正常开关。
阀门需要时维修时：具有免维修的特点，使用中也不必润滑。所有的配件如阀杆、阀座、阀板等都能现场更换，如需更换配件时，将管路泄压关闭后拆下阀门。
本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征，第一特征在第二特征“之下”“下方”和“下面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度小于第一特征。
在本说明书的描述中，参考术语“一个实施例”“一些实施例”“示例”“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中，在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在不脱离本发明的原理和宗旨的情况下在本发明的范围内可以对上述实施例进行变化、修改、替换和变形。
