Abstract: A connector for joining a bowl guard to the housing of a fluid control component which is very simple to use and which permits the use of easily fabricated parts is disclosed. The fluid control component includes a housing with a depending flange to which a plastic or glass bowl is attached, the flange having a peripheral groove therein. The bowl guard has a peripheral lip with a groove that is alignable with the groove of the housing to form an annular recess when the lip of the bowl guard is placed over the flange of the housing in telescopic relationship. A flexible resilient elongated connector, such as a coil spring, having a cross-sectional area substantially corresponding to that of the annular recess is insertable through a notch in the lip into the annular recess and the protrusions of the coil spring are engageable with transverse ribs in the housing groove to hold the connector upon rotation of the bowl guard with respect to the housing. The groove of the bowl guard moves longitudinally therealong until the connector is enclosed within the annular recess after approximately one revolution of the bowl guard to prevent separation of the bowl guard from the housing due to shear forces.

Abstract translation: 公开了一种用于将碗保护件接合到流体控制部件的外壳的连接器，其使用非常简单并且允许使用容易制造的部件。 流体控制部件包括具有悬垂法兰的壳体，塑料或玻璃碗附接到该壳体上，凸缘在其中具有周向槽。 碗保护罩具有带槽的外周唇缘，该凹槽可与壳体的凹槽对准，以在碗形护罩的唇缘以伸缩关系置于壳体的凸缘上方形成环形凹槽。 具有基本上对应于环形凹部的横截面积的柔性弹性细长连接器，例如螺旋弹簧，可插入通过唇缘中的凹口进入环形凹部，并且螺旋弹簧的突出部可与横向肋条 在所述壳体凹槽中，以便在所述保护罩相对于所述壳体旋转时保持所述连接器。 碗形护罩的凹槽沿着其纵向移动，直到连接器在碗状物保护罩大约一转之后被封闭在环形凹槽内，以防止由于剪切力使碗形防护件与壳体分离。
