本发明的最佳实施方式
[0023] 为了便于理解本发明， 下面结合附图对本发明的具体实施例及装配过程作详细 说明。
本发明的实施方式
[0024] 图 1至图 10是气体分流器相关附图。 气体分流器,包括容器 10、 多个球阀、 多个 密封件； 容器 10包括圆柱状的中段 11、 收拢状的前段 12、 收拢状的后段 13， 前 段 12和后段 13通过焊缝 16和焊缝 17连接为一体， 并形成具有空腔 19的容器； 前 段 12上有用于对外连接主管路的流体主通道 14、 后段 13上有泄放接口 15， 中段 1 1的圆柱壁上有 6个接头连接的圆孔 18; 球阀控制支路的通断， 每个球阀包括阀 体、 球状阀芯、 第一阀座组件、 第二阀座组件、 扣合件和阀杆组件， 阀体基本 呈管状， 内部依次安装有扣合件、 第一阀座组件、 球状阀芯、 第二阀座组件， 阀杆组件从阀体的引出孔与球状阀芯连接， 阀体内部具有环状平台， 扣合件被 第一阀座组件固定在阀座内， 同吋第一阀座组件、 第二阀座组件构成一对密封 副， 作用在球状阀芯上， 球状阀芯可以在阀杆组件的驱动下、 在密封副之间转 动， 实现阀门通断； 扣合件从阀体的第一端延伸出来， 阀体第一端端面呈平面
， 在该端面上有围绕扣合件的环形凹槽； 扣合件 30包括塑变部 33、 薄壁部 32、 外沿部 31、 突起部 322和中心孔， 薄壁部 32的外部直径与塑变部 33外部直径相同 ， 薄壁部 32塑变前中心孔直径大于阴螺纹部直径， 薄壁部 32的壁厚小于塑变部 3 3壁厚； 薄壁部 32外壁设置有拉丝纹 321以提高扣合件与容器内壁的摩擦力， 外 沿部 31的下缘 311设置有纹路以提高扣合件与接头的摩擦力， 塑变部的前端 333 呈收拢状， 扣合件 30的中心孔贯通塑变部 33、 薄壁部 32和外沿部 31 ; 扣合件 30 的塑变部 33和薄壁部 32依次穿过密封件 40和容器圆孔 18， 在轴向、 相向方向上 的外力作用下， 薄壁部 32塑变塌陷、 并向薄壁部径向向外鼓起， 形成突起部 322 ， 使扣合件外沿部 31的下缘 311抵顶在阀体内部的环状平台 24上、 突起部 322抵 顶在环绕圆孔 18的容器内壁上， 实现阀体与容器 10形成轴向夹紧， 扣合件 30塑 变吋压迫容器壁也发生塑变， 使容器 10外壁贴合在阀体第一端面 23上， 并将密 封件 40封闭在凹槽 26内。
图 7-图 10展示了一个气体分流器的阀门支路安装方式， 安装过程需要夹紧设备 —芯轴， 芯轴主体能穿过图 3所示球阀的流道， 并且具有一个流线型膨大部 51 ， 芯轴 50的主体能穿过整个阀门支路的流道， 但膨大部 51能穿过除扣合件阴螺 纹 332以外的区域。 安装吋， 首先将芯轴 50的主体自扣合件 30—端穿过整个球阀 的流道， 而后将膨大部 51、 扣合件 30穿过密封件 40、 孔 18， 用力 F1抵顶在飼门 6 0上， 同吋用 F2抽取芯轴 50， 力通过球阀 60传递到扣合件的上缘 312上， 与此同 吋膨胀部 51强行挤入扣合件的塑变部 33， 使得扣合件 30轴向压缩， 薄壁部 32幵 始向径向向外鼓起,形成突起部 322， 随着力 Fl、 F2逐渐加大， 突起部 322抵顶在 容器 10内壁， 并压迫容器贴合在接头 20的端面 23上， 随着力 Fl、 F2继续加大， 膨胀部 51将塑变部 33的阴螺纹 332损坏、 挤平滑， 最后膨胀部 51抽离处阀门支路 。 这种安装方式会对扣合件的阴螺纹造成永久破坏， 但不会对连接强度造成负 面影响； 将阴螺纹挤压平滑， 还能将塑变部 33的内径扩大， 提高流体的流通能 力。
图 6所示的是另外一种结构的扣合件， 这种扣合件 31 '与图 5所示的扣合件 30区别 在于塑变部 33'内部不含有螺纹， 而是多个环形槽 332'， 环形槽 332'相对阴螺纹 33 2具有塑变破坏力容易控制和调节， 再者， 环形槽塑变吋不容易局部脱落、 掉屑 ， 不污染气体分流器。
