用于阀体的检修阀和阀组件
摘要：
本发明提供一种用于阀体的检修阀，检修阀包括：基部，所述基部相对于所述阀体在打开取向和闭合取向之间可旋转；其中，所述打开取向允许流体通过检修阀流入阀体中，以及闭合取向阻止流体通过检修阀流入阀体中；以及从所述基部延伸的突出部，其中当所述基部处于所述打开取向时，所述突出部防止盖从所述阀体去除。本发明还提供一种阀组件，包括：阀体，所述阀体具有入口端口、出口端口和用于接收从一组可互换阀芯中选择的阀芯的开口；帽，所述帽配置成可释放地联接到所述阀体，其中当联接到所述阀体时所述帽覆盖所述阀体中的圆形开口；以及检修阀；其中当所述检修阀处于打开位置时从所述检修阀延伸的突出部防止从所述阀体中的所述开口去除所述帽。
摘要（英）：

The invention provides a service valve for a valve body. The service valve includes a base rotatable between an open orientation and a closed orientation relative to the valve body. When the base is in the open orientation, the service valve allows fluid flow into the valve body through the service valve. When the base is in the closed orientation, the service valve blocks the fluid flow into the valve body through the service valve. The service valve further includes a tab extending from the base. The tab prevents removal of a cover from the valve body when the base is in the open orientation. The invention further discloses a valve assembly including a universal valve body, a cap, and a service valve. The valve body may include an inlet port, an outlet port, and a circular opening for receiving a valve cartridge selected from a set of interchangeable cartridges. The cap may be configured to releasably couple to the valve body for covering the circular opening in the valve body. When the service valve is on an open position, the extending tab of the service valve prevents the cap from being removed from the opening of the valve body.
