Abstract

本发明公开了一种利用波纹管密封的球阀，包括阀体、阀座、球体、阀杆，在阀体的法兰端固装阀座套，阀座套底部设置与阀座底面接触的底部延伸板，阀座与阀座套之间呈凹槽形式，波纹管设置在凹槽中，波纹管的一端与阀座焊接，波纹管的另一端与阀座套焊接。使用方法：通过密封垫调整波纹管的弹力；球体转动时，阀座受压推动波纹管，减小密封面的摩擦力。

Description

利用波纹管密封的球阀
技术领域
本发明涉及一种利用波纹管密封的球阀。
背景技术
球阀的开关过程中，球体始终与阀座紧贴，接触表面存在确保密封的密封力；特别是高压阀门密封力大，摩擦剧烈，不仅驱动力矩大、成本高、能耗高，而且密封面使用寿命短。
发明内容
本发明的目的在于提供一种结构合理，开关过程摩擦小、使用寿命长的利用波纹管密封的球阀。
本发明的技术解决方案是：
一种利用波纹管密封的球阀，包括阀体、阀座、球体、阀杆，其特征是：在阀体的法兰端固装阀座套，阀座套底部设置与阀座底面接触的底部延伸板，阀座与阀座套之间呈凹槽形式，波纹管设置在凹槽中，波纹管的一端与阀座焊接，波纹管的另一端与阀座套焊接。
阀座套通过螺钉和密封垫与阀体固定。
波纹管与阀座、阀座套的上端焊接。
使用方法：通过密封垫调整波纹管的弹力；球体转动时，阀座受压推动波纹管，减小密封面的摩擦力。
本发明结构合理，开关过程摩擦小、使用寿命长。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1是本发明一个实施例的结构示意图。
具体实施方式
一种利用波纹管密封的球阀，包括阀体1、阀座2、球体3、阀杆4，在阀体的法兰端固装阀座套5，阀座套底部设置与阀座底面接触的底部延伸板6，阀座与阀座套之间呈凹槽7形式，波纹管8设置在凹槽中，波纹管的一端与阀座焊接，波纹管的另一端与阀座套焊接。
阀座套通过螺钉9和密封垫10与阀体固定。波纹管与阀座、阀座套的上端焊接。
使用方法：通过密封垫调整波纹管的弹力；球体转动时，阀座受压推动波纹管，减小密封面的摩擦力。
