Improvements in nozzles for injecting substances into liquids
摘要：
An injection nozzle (10) is installed in the wall (13) of a liquid containment vessel (14) and comprises an assembly of refractory component bodies (18, 19, 20); injection passages (22) for receiving longitudinally movable lances (11) are provided in the nozzle and before injection commences, the passages are closed by cup-shaped refractory shells (30) embedded in one of the component bodies (18) adjacent a discharge end of the nozzle. Each shell has its base (31) united through a frangible shell portion (34) with the sidewall (32) and when injection is to commence, an associated lance (11) is forcibly driven at the base (31) to detach it by fracture of the shell portion (34) and form an opening through which an injectant can exit into the liquid. A push-out bung (26) may be inc­orporated in the nozzle body (18) between the base of the shell (30) and the discharge end of the nozzle (10).
摘要（中）：

注射喷嘴（10）安装在液体容纳容器（14）的壁（13）中，并且包括耐火组分体（18,19,20）的组件; 在喷嘴中设置用于接收纵向移动的喷枪（11）的喷射通道（22），并且在喷射开始之前，通过嵌入在一个组件体（18）中的杯形耐火壳（30）封闭通道，邻近排放端 的喷嘴。 每个壳体的基部（31）通过具有侧壁（32）的易碎壳部分（34）联合，并且当注射开始时，相关联的喷枪（11）在基部（31）被强制驱动以通过断裂将其分离 的外壳部分（34），并形成一个开口，注射剂可以通过该开口离开液体。 可以在壳体（30）的基部和喷嘴（10）的排出端之间的喷嘴主体（18）中并入推出栓（26）。
