摘要： A device for terminating the flow of fire-extinguishing fluid from an activated sprinkler head of the pendent and sidewall types. A cavity within the device receives the sprinkler head and a protuberance within said cavity engages the valve assembly and returns the shut-off valve to the fluid-emitting conduit. Biased apertures within the sidewalls engage the sprinkler head flange and provide a locking means. The device is constructed from thermoplastic resins which melt and allow the device to become reactivated when ambient temperatures reach critical levels.
摘要翻译：用于终止来自侧壁和侧壁类型的活化喷洒头的灭火流体流动的装置。装置内的空腔接收喷洒头，并且在所述空腔内的突起与阀组件接合并将截止阀返回到流体发射管道。侧壁内的偏置孔接合喷洒头凸缘并提供锁定装置。该设备由热塑性树脂构成，当环境温度达到临界水平时，该热塑性树脂会熔化并允许设备重新激活。

摘要： A device for terminating the flow of fluid from an overhead sprinkler equipped with a cut-off valve. The device provides a cut-off means for obturating fluid flow in sprinkler heads equipped with both a circular baffle and a baffle having a sidewall member for directing water into a limited area. When impressed onto the sprinkler head a recessed segment returns the cut-off valve to its original shut-down position and a biased locking means allows the user to secure the device against unintended discharge.
摘要翻译：一种用于从装有截止阀的头顶喷洒器终止流体流动的装置。该装置提供了一种截止装置，用于在配备有圆形挡板和挡板的喷洒头中堵塞流体流动，该挡板具有用于将水引导到有限区域中的侧壁构件。当喷洒在喷头上时，凹入部分将截止阀返回到其初始关闭位置，并且偏置的锁定装置允许使用者固定装置以防意外排出。

摘要： A thermally responsive device for terminating the discharge of fire-extinguishing fluid from an activated sprinkler head of the pendent and sidewall type. The device includes a recessed seat which, when impressed onto an activated sprinkler head, returns the shut-off valve to the water emitting conduit to obturate fluid flow. The device is secured by a frictional locking means which allows it to remain in place as a guard against inadvertent discharge.
